Definitions
- EMAR Electronic Medical Administration Records
- a nurse In many hospital environments, a nurse must walk to a central location (e.g., a pyxis machine) at which medication is handled to obtain medication for a particular patient. Often, to avoid giving the wrong medication to a patient, the nurse only carries one patient's medication at a time. This control, however, does not preclude the potential for the medication to be given to the wrong patient such as, for example, if the nurse is sidetracked and asks another nurse to administer the medication.

- the medical cart 500 includes a work platform 340 , a support mechanism 320 that supports and adjusts the height of the work platform 340 , and a base 310 .
- the work platform 340 can include a bi-directional laptop platform 370 , a bi-directional work surface 350 , an adjustable barcode scanner holder 380 , an adjustable clipboard 390 , one or more lockable compartments 530 , a plurality of top bins 342 , removable side bins 520 , cup holders 344 , and/or a keypad 238 . Because each of these items is provided on the work platform 340 , a user can ergonomically access each of these items as the work platform 340 is raised or lowered.
- the laptop platform 370 can be configured to support, for example, a laptop computer 900 (shown in FIGS. 6A and 7). Conventional structure can be provided on the laptop platform 370 to hold the laptop computer in place.
- the laptop platform 370 can have an arcuate front face 376 at a front portion. The arcuate front face 376 may be designed to correspond to the torso of a user for ergonomic reasons.
- the laptop platform 370 can be locked in a central position (FIG. 1) or adjusted ergonomically to a forward (FIG. 2A) or rearward (FIG. 2B) position.
- FIG. 1 a central position
- FIG. 2A forward
- FIG. 2B rearward
- a transfer structure 800 allows the laptop platform 370 to be moved between those positions.
- the transfer structure 800 can include stationary rails 372 mounted on body portions 802 of the work platform 340 and rails runners 373 mounted on the laptop platform 370 , as shown in FIGS. 2A and 2B.
- Notches 374 which include sloped surfaces 375 and cavities 377 , are formed along the rail runners 373 .
- the notches 374 are configured to engage posts 371 formed along the stationary rails 372 .
- the sloped surfaces 375 of the notches 374 are configured to engage the posts 371 .
- the posts 371 will ride up the sloped surfaces 375 and be deposited in cavities 377 in the notches 374 , thereby releasably immobilizing the laptop platform 370 with respect to the work platform 340 .
- one notch 374 may be provided on each of the rail runners 373 and corresponding posts 371 may be provided on the stationary rails 372 .
- the laptop platform 370 can be releaseably locked with respect to the work platform 340 .
- the posts 371 may be provided at rear portions of the stationary rails 372 and the notches 374 may be similarly provided at rear portions of the rail runners 373 .
- the laptop platform 370 will be releaseably locked with respect to the work platform 340 when in a central position shown in FIG. 1.
- each of the stationary rails 372 may include at least three posts 371 , one provided at each end of the stationary rails 372 and one provided in a central portion of the stationary rails 372 .
- each of the rail runners 373 may include three notches 374 , one provided at each end of the rails runners 373 and one provided in a central portion of the rail runners 373 .
- the surface 370 can be releasably immobilized with respect to the work platform 340 in a forward position (FIG. 2A), a rearward position (FIG. 2B), and a central position (FIG. 1). In the forward position (FIG.
- the rearmost notches 374 may be engaged with the forwardmost posts 371 .

- all three posts 371 on each stationary rail 372 may be engaged with the corresponding cavity 377 of the notches 374 of the rail runners 373 .
- the contact between the stationary rails 372 and the rail runners 373 can be frictionally enhanced such that the laptop platform 370 does not readily slide with respect to the work platform 340 . Rather, force (i.e., either pushing or pulling on the laptop platform 370 ) will be required to overcome the frictional engagement between the stationary rails 372 and the rail runners 373 . As a result, the laptop platform 370 can be relatively fixed with respect to the work platform 340 at any location between a forwardmost position (FIG. 2A) and a rearmost position (FIG. 2B).
- one or more notches 374 /posts 371 may be combined with the frictional engagement between the stationary rails 372 and the rail runners 373 .
- the laptop platform 370 When the laptop platform 370 is pushed forward or rearward, it can expose a secondary work area 379 provided below the laptop platform 370 .
- the secondary work area 379 can be particularly sturdy. For example, it can be sturdy enough to enable a user to crush pills on the secondary work area 379 .
- the secondary work area 379 may be provided with a rim 378 .
- the rim 378 may reduce the likelihood of medication rolling off the medical cart 500 such as, for example, when a nurse tries to crush pills on the secondary work area 379 .
- the bi-directional work surface 350 is shown in FIGS. 3A, 3B, 3 C, 4 A, and 4 B. As shown in FIGS. 3A and 3B, the bi-directional work surface 350 is positioned below the laptop platform 370 . The bi-directional work surface 350 is designed to move through a slot 343 in the side 341 of the work platform 340 in leftward and rightward directions to provide additional work space.
- the work surface 350 can have channels 355 , 357 on its underside that engage ribs 358 , 359 formed on a plate 361 provided on a body 329 of the work platform 340 .
- the channels 355 , 357 are sized to receive the ribs 358 , 359 of the plate 361 .
- the channels 355 , 357 are closed at one end. As a result, when the second bi-directional work surface 350 slides to the right (as shown in FIG. 4A), the channels 355 will slide along the ribs 358 , 359 .
- the channels 355 will slide past the ribs 359 on the left side of the plate 361 and will continue to slide along ribs 358 on the right side of the plate 361 .
- the second bi-directional work surface 350 will stop sliding, however, when the closed ends 363 of the channels 355 abut the inner ends of ribs 358 .
- the channels 357 will slide along the ribs 358 , 359 .
- the channels 357 will slide past the ribs 358 on the right side of the plate 361 and will continue to slide along ribs 359 on the left side of the plate 361 .
- the second bi-directional work surface 350 will stop sliding, however, when the closed ends 365 of the channels 357 abut the inner ends of the ribs 359 .
- the bi-directional work surface 350 slides to the right or to the left, it slides in an arcuate path as a result of the channels 355 , 357 and ribs 358 , 369 (and the work surface 350 ) being arcuate in shape.
- the second bi-directional work surface 350 is positioned closer to a user standing or sitting in front of the medical cart 500 when it is in an extended position.
- a releaseable locking mechanism 1000 (shown best in FIG. 3C) can be provided to hold the work surface 350 in a center position and to prevent it from sliding unintentionally.
- the second bi-directional work surface 350 may be provided with a projection 354 having sloped surfaces 347 and a nesting region 346 .
- the plate 361 may be provided with a moveable pin 356 which may be, for example, a ball spring plunger that is spring-biased in upward direction (i.e., toward the work surface 350 ).
- the moveable pin 356 will initially be pushed downward relative to the plate 361 by the sloped surface 347 of the projection 354 . Subsequently, the pin 356 will extend upwards into the nesting region 346 of the projection 354 and become frictionally engaged therein, thereby releasably locking the work surface 350 with respect to the work platform 340 .
- a force is applied to one of the exposed ends of the second bi-directional work surface 350 (to push the moveable pin 356 out of the nesting region 346 of the curved projection 354 ), thereby enabling the bi-directional work surface 350 to slide freely along the ribs 358 , 359 .
- the type of locking mechanism may be changed.
- additional movable pins 356 may be provided in the plate 361 so as to enable the second bi-directional work surface 350 to be releasably locked in a corresponding number of positions.
- the adjustable barcode scanner holder 380 includes a flexible neck 382 , a base 386 , and a holder portion 384 .
- the position of the holder portion 384 can be adjusted.
- the vertical distance between the holder portion 384 and the laptop platform 370 can be adjusted.
- the orientation of the holder portion 384 can be adjusted between, for example, a holding position in which a barcode scanner 385 is maintained in an upright holding position (FIG. 5B) and a hands-free scanning position in which the holder portion 384 is adapted to hold an inverted (i.e., facing downward) barcode scanner 385 .
- the holder portion 384 By holding the scanner 385 in the inverted position, the holder portion 384 enables a user to pass documents between the scanner 385 and the laptop platform 370 (FIG. 5C), without having to manually hold the scanner 385 (i.e., the scanner 385 may be operated in a hands-free manner). Moreover, the flexibility of the neck 382 enables the holder portion 384 to be adjusted to accommodate various barcode scanner sizes. In addition, the neck 382 is designed to rotate at the base 386 thereof so that a user can turn the barcode scanner holder 380 away from the laptop platform 370 , if desired.
- the barcode scanner 385 may be an integral part of the medical cart 500 or may be detachable therefrom. If the barcode scanner 385 is an integral component of the medical cart 500 , its power cord 387 may be inserted into a power cord passage 327 and connected to an electrical receptacle 904 , as later explained in detail with respect to FIGS. 11-13. By way of contrast, the barcode scanner 385 may receive the power necessary to operate it from a laptop computer 900 when it is plugged into a USB port of the laptop computer 900 .
- the adjustable clipboard 390 is also designed to hold items in a hands-free manner.
- the clipboard 390 includes a clip 392 for holding items, such as paper.
- the clipboard 390 also includes conventional rails 394 attached to an L-shaped metal bracket 393 which connects the clipboard 390 to the laptop platform 370 , as shown best in FIG. 6C.
- the clipboard 390 is designed to slide along the rails 394 to the left of the medical cart 500 .
- the clipboard 390 can be moved from a central position (FIG. 6B) to left of the laptop computer to allow the user to view the documents clipped to the clip 392 , as shown in FIGS. 6A and 6C.
- the clipboard 390 could be designed to move to the right.
- the plurality of compartments 530 face the user and move up and down with the work platform 340 (i.e., they remain in the same position relative to the laptop platform 370 ), which are ergonomically desirable features.
- the compartments 530 may be provided with labeling portions 570 , which allow labels to be displayed on the compartments 530 .
- the plurality of compartments 530 enable a user (e.g., a nurse) to separately maintain medication for particular patients or for a particular room. For example, if a nurse is responsible for eight patients in a hospital ward, the medical cart 500 may be provided with a corresponding number of compartments 530 and the medication for each patient may be kept in a separate drawer assigned to that patient.
- the nurse could load the medication for all eight patients into eight separate drawers at one time (e.g., at the start of a medication pass) and at one location (e.g., at a pyxis machine), thereby reducing the need to travel to obtain the medication during the nurse's shift.
- the compartments 530 have projections 531 which are configured to slide in grooves 533 formed on the interior walls of the medical cart 500 .
- the compartments 530 in FIG. 1 are shown as having a generally uniform height, this is not required. In some embodiments the compartments 530 may have different heights.
- dividers 535 which may be, for example, sheet metal.
- dividers 535 which may be, for example, sheet metal.
- a tall space 537 may be created.
- a tall compartment 530 E the height of which is substantially equal to height of the four short compartments 530 A-D when installed in the medical cart 500 , may be inserted into medication module 500 to substantially fill the space 537 .
- the tall compartment 530 E will readily slide into the medical cart 500 by means of the projections 531 which are configured to slide into the grooves 533 previously occupied by the projections 531 of the upper short compartment 530 A.
- different size compartments 530 can be accommodated based on the desired application.
- the compartments 530 may be lockable by means of a keyless entry system (the details of which are later described with respect to FIGS. 22 and 23). Thus, the potential for unauthorized access to the compartments 530 while the nurse is caring for a particular patient is small.
- the top bins 243 are provided to house items such as paperclips, pencils, etc.
- the cup holders 344 are provided to secure a number of medicine cups used to pass out medications.
- the removable side bins 520 can be provided to hold items, such as trash or medical equipment.
- the side bins 520 can be removably connected to the sides of the body 329 of the work platform 340 by conventional means, such as a hole and pin arrangement.
- the work platform 340 may be raised and lowered by means of the support mechanism 320 .
- This provides a sitting or standing user with easy access to the work surface 350 and its associated components (e.g., laptop platform 370 , work surface 350 , compartments 530 , etc.).
- the support mechanism 320 allows the user to adjust the position of the work platform 340 to a comfortable position, regardless of whether the user is sitting or standing.
- the support mechanism 320 comprises two telescoping portions 322 , 324 (shown more clearly in the embodiment shown in FIG. 16) and height adjustment mechanism 400 (shown in FIGS. 9A and 9B).
- the height adjustment mechanism 400 enables a standing user or a sitting user to ergonomically raise and lower the work platform 340 .
- the height adjustment mechanism 400 includes an outer casing 410 , a telescoping inner casing 420 , and a driver 430 .
- two or more drawer slides 422 are provided between the inner casing 420 and the outer casing 410 .
- two drawer slides 422 may be used (on opposite sides of the inner casing 420 ), it is preferable to use at least three drawer slides 422 , to prevent (or at least greatly inhibit) a binding action from being applied to the height adjustment mechanism 400 by means of a cantilevered force being applied thereto.
- the drawer slides 422 may be, for example, conventional drawer rails formed of stationary drawer rails 423 and corresponding rail runners 425 . If the drawer slides 422 are conventional drawer rails, one side of the drawer slides 422 (e.g., the rail runners 425 ) may be fixed to outer sides of the inner casing 420 and the corresponding side of the drawer slides 422 (e.g., the stationary drawer rails 423 ) may be fixed to inner sides the outer casing 420 . Further, the stationary drawer rails 423 may be provided with ball bearings to facilitate movement of the rail runner 425 . An upper end of one side of the inner casing 420 is provided with an engagement mechanism 426 . As shown, the engagement mechanism may be in the form of a window in the side of the casing 420 .
- the driver 430 includes a gas driven piston 432 which, in turn, includes a body portion 436 and a telescoping strut 434 .
- the driver 430 is controlled by an actuator 440 to which is connected by a connector 442 .
- a base 411 of the outer casing 410 is affixed to the base 310 of the medical cart 500 by a plurality of bolts through the base 411 .
- a bolt 413 passes through a hole 437 in a connection portion 439 of the body portion 436 of the piston 432 , thereby immobilizing both the outer casing 410 and the piston 432 .
- the inner casing 420 and the telescoping strut 434 are affixed to work platform 340 by an upper bolt 415 which passes through the inner casing 420 and through a hole 459 in a connection portion 460 of the telescoping strut 434 .
- the actuator 440 may be provided in a front portion of the medical cart 500 .
- a button 444 of the actuator 440 may be provided in the handle 360 of the medical cart 500 , as shown in FIG. 1.
- the button 444 is pushed as a user pushes down on work platform 340 thereby causing the gas driven piston 432 to expel air.
- the telescoping strut 434 is withdrawn vertically into the body portion 436 of the piston 432 .
- the work platform 340 which is affixed to the telescoping strut 434 also moves downward.
- the work platform 340 forces the connection portion 460 and the inner casing 420 to move downward. If the button 444 is released while the work platform 340 is being lowered, the work platform 340 will be releaseably locked at the height at which the button 444 is released. As a result, the work platform 340 can be releaseably locked at any position between a lowest position (at which the telescoping strut 434 is maximally provided in the body portion 436 of the piston 432 ) and a highest position (at which the inner casing 420 is driven upward to a maximum distance by the telescoping strut 434 of the piston 432 ).
- the medical cart can include a power cord passage 327 that enables a power cord 902 of a laptop computer 900 (or other device) on the laptop platform 370 to be electrically connected to an electrical receptacle 904 provided in the base 310 .
- the electrical receptacle 904 can be connected, for example to a wall outlet via a retractable cord 906 , as later described.
- the passage 327 includes an access hole 325 in the work platform 340 and extends through the telescoping portions 322 , 324 .
- the passage 327 terminates in a well 960 in the base 310 where the electrical connection can occur. This permits the point of connection to the electrical receptacle 904 to be enclosed.
- the well 960 in the base 310 houses the electrical receptacle 904 , a retractable cord 906 , and a hatch 908 that provides access to the well 960 so that power cords 387 , 902 can be plugged into the electrical receptacle 904 .
- the retractable cord 906 can be plugged into an external wall outlet to recharge the battery internal to the laptop computer 900 and/or a battery-powered solenoid 240 in the keyless entry system (later described in detail).
- the hatch 908 works in conjunction with a cover plate 910 to enclose the base 310 including the well 960 , thereby encapsulating the components provided in the base 310 and shielding them from the environment.
- the base 310 which is moveable by means of rolling members 120 (e.g., casters), is ergonomically shaped to provide stability.
- the base 310 is designed to provide stability by having the rolling members 120 at corners which are outside of the footprint of the work platform 340 .
- the rolling members 120 are spaced-apart to such a degree that two rolling members 123 of a medication module 100 can be located between two rolling members 121 of the base 310 , thereby enabling the medical cart 500 and the medication module 100 to nest together.
- a second locking mechanism 190 provided on an underside of the base 310 (shown in FIGS. 1 and 15), also as later described in detail.

Abstract
Description
- This application claims priority to U.S. Provisional Application No. 60/448,920 (filed Feb. 24, 2003), No. 60/484,658 (filed Jul. 7, 2003), and No. 60/518,649 (filed Nov. 12, 2003). This application also claims priority to U.S. Design patent application Nos. 29/196,712, 29/196,713, 29/196,714 (all filed Jan. 2, 2004) and to U.S. Design patent application Ser. Nos. ______, and ______ (filed concurrently herewith).
- The Institute of Medicine estimates that medical error is responsible for roughly 98,000 deaths annually, making it the seventh leading cause of death in the U.S. Accordingly, reducing the likelihood of error is an important issue not only for hospitals and doctors, but for society as a whole.
- To alleviate some of these concerns, some hospitals provide nurses with medical carts on which a networked laptop computer facilitates the use of Electronic Medical Administration Records (“EMAR”). EMAR is an electronic record of medications and services administered by a healthcare professional through patient and medication identification via bar coding. When admitted into a hospital, the patient receives a bar coded wrist band for identification purposes. Also, healthcare professionals within the pharmacy bar code all the medications to be administered to the patients. Documentation of medications given at the point-of-care has reduced the number of errors by ensuring that the right patient is receiving the proper medication at the correct time. The EMAR software alerts the nurse if there is a discrepancy anytime during the medication administration process.
- Unfortunately, however, these medical carts have proven unsatisfactory for a number of reasons. For example, the carts are not ergonomically designed. The average age of a nurse is 47 and roughly 83% of nurses report suffering chronic back pain. In addition, the existing EMAR carts suffer from a relative lack of work surface, lack of an area to dispose of refuse, bad placement of medication drawers, lack of storage space, and relative inability to be usefully raised and lowered to enable the nurse to work when either standing or sitting.
- In many hospital environments, a nurse must walk to a central location (e.g., a pyxis machine) at which medication is handled to obtain medication for a particular patient. Often, to avoid giving the wrong medication to a patient, the nurse only carries one patient's medication at a time. This control, however, does not preclude the potential for the medication to be given to the wrong patient such as, for example, if the nurse is sidetracked and asks another nurse to administer the medication.
- In addition to the above-mentioned concerns, when one takes into account the number of patients which a nurse must handle, the result is that the nurse must spend a considerable amount of time walking between the central location and each patient's bedside. This problem is exacerbated in some situations in which the central location is located a significant distance from one or more of the patients for which the nurse is responsible. Moreover, the cost associated with paying nurses to continuously travel to and from various medication locations may be relatively insignificant at the level of a particular nurse but is quite significant to the medical industry as a whole.
- What is needed, therefore, is an apparatus and a methodology by which medical error may be reduced and by which the amount of time a nurse spends obtaining and researching medication may be reduced, without compromising safety.
- An aspect of the present invention relates to a cart including a work platform having a work surface and at least one compartment, a base, and a height adjustment mechanism for adjusting the height of the work platform relative to the base. The compartment can be a drawer. The work platform can accommodate drawers of different sizes. Preferably the compartment is configured to be unlocked via a keyless entry system.

- Presently preferred embodiments of the invention are illustrated in the drawings. An effort has been made to use the same or like reference numbers throughout the drawings to refer to the same or like parts.
- A first embodiment of a
medical cart 500 is shown in FIGS. 1-15. With respect to FIG. 1, it can be seen that themedical cart 500 includes awork platform 340, asupport mechanism 320 that supports and adjusts the height of thework platform 340, and abase 310. - The
work platform 340 can include abi-directional laptop platform 370, abi-directional work surface 350, an adjustablebarcode scanner holder 380, anadjustable clipboard 390, one or morelockable compartments 530, a plurality oftop bins 342,removable side bins 520,cup holders 344, and/or akeypad 238. Because each of these items is provided on thework platform 340, a user can ergonomically access each of these items as thework platform 340 is raised or lowered. - The
laptop platform 370 can be configured to support, for example, a laptop computer 900 (shown in FIGS. 6A and 7). Conventional structure can be provided on thelaptop platform 370 to hold the laptop computer in place. Thelaptop platform 370 can have an arcuatefront face 376 at a front portion. The arcuatefront face 376 may be designed to correspond to the torso of a user for ergonomic reasons. - The
laptop platform 370 can be locked in a central position (FIG. 1) or adjusted ergonomically to a forward (FIG. 2A) or rearward (FIG. 2B) position. As an example of a use of the present invention, when a user lowers thework platform 340 to a low position and moves thelaptop platform 370 to a forward position, the user can sit and thework platform 340 functions as a desk. Atransfer structure 800 allows thelaptop platform 370 to be moved between those positions. Thetransfer structure 800 can includestationary rails 372 mounted onbody portions 802 of thework platform 340 andrails runners 373 mounted on thelaptop platform 370, as shown in FIGS. 2A and 2B. -
Notches 374, which include slopedsurfaces 375 andcavities 377, are formed along therail runners 373. Thenotches 374 are configured to engageposts 371 formed along the stationary rails 372. When thelaptop platform 370 is moved by thetransfer structure 800, thesloped surfaces 375 of thenotches 374 are configured to engage theposts 371. By continuing to push (or pull) thelaptop platform 370, theposts 371 will ride up the slopedsurfaces 375 and be deposited incavities 377 in thenotches 374, thereby releasably immobilizing thelaptop platform 370 with respect to thework platform 340. - In one embodiment, one
notch 374 may be provided on each of therail runners 373 andcorresponding posts 371 may be provided on the stationary rails 372. As a result, thelaptop platform 370 can be releaseably locked with respect to thework platform 340. For example, as shown in FIGS. 2A and 2B, theposts 371 may be provided at rear portions of thestationary rails 372 and thenotches 374 may be similarly provided at rear portions of therail runners 373. As a result, thelaptop platform 370 will be releaseably locked with respect to thework platform 340 when in a central position shown in FIG. 1. - In another embodiment, each of the
stationary rails 372 may include at least threeposts 371, one provided at each end of thestationary rails 372 and one provided in a central portion of the stationary rails 372. Correspondingly, each of therail runners 373 may include threenotches 374, one provided at each end of therails runners 373 and one provided in a central portion of therail runners 373. As a result, thesurface 370 can be releasably immobilized with respect to thework platform 340 in a forward position (FIG. 2A), a rearward position (FIG. 2B), and a central position (FIG. 1). In the forward position (FIG. 2A), therearmost notches 374 may be engaged with the forwardmost posts 371. Similarly, in the rearward position (FIG. 2B), thefowardmost notches 374 may be engaged with the rearmost posts 371. Finally, in the central position, all threeposts 371 on eachstationary rail 372 may be engaged with thecorresponding cavity 377 of thenotches 374 of therail runners 373. - In another embodiment, the contact between the
stationary rails 372 and therail runners 373 can be frictionally enhanced such that thelaptop platform 370 does not readily slide with respect to thework platform 340. Rather, force (i.e., either pushing or pulling on the laptop platform 370) will be required to overcome the frictional engagement between thestationary rails 372 and therail runners 373. As a result, thelaptop platform 370 can be relatively fixed with respect to thework platform 340 at any location between a forwardmost position (FIG. 2A) and a rearmost position (FIG. 2B). In addition, one ormore notches 374/posts 371 may be combined with the frictional engagement between thestationary rails 372 and therail runners 373. - When the
laptop platform 370 is pushed forward or rearward, it can expose asecondary work area 379 provided below thelaptop platform 370. Thesecondary work area 379 can be particularly sturdy. For example, it can be sturdy enough to enable a user to crush pills on thesecondary work area 379. In addition, thesecondary work area 379 may be provided with arim 378. Therim 378 may reduce the likelihood of medication rolling off themedical cart 500 such as, for example, when a nurse tries to crush pills on thesecondary work area 379. - The
bi-directional work surface 350 is shown in FIGS. 3A, 3B, 3C, 4A, and 4B. As shown in FIGS. 3A and 3B, thebi-directional work surface 350 is positioned below thelaptop platform 370. Thebi-directional work surface 350 is designed to move through aslot 343 in theside 341 of thework platform 340 in leftward and rightward directions to provide additional work space. - The
work surface 350 can havechannels ribs plate 361 provided on a body 329 of thework platform 340. Thechannels ribs plate 361. To prevent thebi-directional work surface 350 from sliding off theplate 361, thechannels bi-directional work surface 350 slides to the right (as shown in FIG. 4A), thechannels 355 will slide along theribs channels 355 will slide past theribs 359 on the left side of theplate 361 and will continue to slide alongribs 358 on the right side of theplate 361. The secondbi-directional work surface 350 will stop sliding, however, when the closed ends 363 of thechannels 355 abut the inner ends ofribs 358. - Similarly, when the second
bi-directional work surface 350 slides to the left (as shown in FIG. 4B), thechannels 357 will slide along theribs channels 357 will slide past theribs 358 on the right side of theplate 361 and will continue to slide alongribs 359 on the left side of theplate 361. The secondbi-directional work surface 350 will stop sliding, however, when the closed ends 365 of thechannels 357 abut the inner ends of theribs 359. - When the
bi-directional work surface 350 slides to the right or to the left, it slides in an arcuate path as a result of thechannels ribs 358, 369 (and the work surface 350) being arcuate in shape. As a result, the secondbi-directional work surface 350 is positioned closer to a user standing or sitting in front of themedical cart 500 when it is in an extended position. - A releaseable locking mechanism1000 (shown best in FIG. 3C) can be provided to hold the
work surface 350 in a center position and to prevent it from sliding unintentionally. For example, as shown in FIGS. 3B and 3C, the secondbi-directional work surface 350 may be provided with aprojection 354 having slopedsurfaces 347 and anesting region 346. Correspondingly, theplate 361 may be provided with amoveable pin 356 which may be, for example, a ball spring plunger that is spring-biased in upward direction (i.e., toward the work surface 350). As a result, when thebi-directional work surface 350 is pushed into the work platform 340 (from either the left or the right), themoveable pin 356 will initially be pushed downward relative to theplate 361 by the slopedsurface 347 of theprojection 354. Subsequently, thepin 356 will extend upwards into thenesting region 346 of theprojection 354 and become frictionally engaged therein, thereby releasably locking thework surface 350 with respect to thework platform 340. To move thework surface 350 out of the locked position, a force is applied to one of the exposed ends of the second bi-directional work surface 350 (to push themoveable pin 356 out of thenesting region 346 of the curved projection 354), thereby enabling thebi-directional work surface 350 to slide freely along theribs - Of course, the type of locking mechanism may be changed. Further, additional
movable pins 356 may be provided in theplate 361 so as to enable the secondbi-directional work surface 350 to be releasably locked in a corresponding number of positions. - As shown in FIGS. 5A-5C, the adjustable
barcode scanner holder 380 includes aflexible neck 382, abase 386, and aholder portion 384. As a result of theneck 382 being flexible, the position of theholder portion 384 can be adjusted. For example, the vertical distance between theholder portion 384 and thelaptop platform 370 can be adjusted. Specifically, the orientation of theholder portion 384 can be adjusted between, for example, a holding position in which abarcode scanner 385 is maintained in an upright holding position (FIG. 5B) and a hands-free scanning position in which theholder portion 384 is adapted to hold an inverted (i.e., facing downward)barcode scanner 385. By holding thescanner 385 in the inverted position, theholder portion 384 enables a user to pass documents between thescanner 385 and the laptop platform 370 (FIG. 5C), without having to manually hold the scanner 385 (i.e., thescanner 385 may be operated in a hands-free manner). Moreover, the flexibility of theneck 382 enables theholder portion 384 to be adjusted to accommodate various barcode scanner sizes. In addition, theneck 382 is designed to rotate at thebase 386 thereof so that a user can turn thebarcode scanner holder 380 away from thelaptop platform 370, if desired. - The
barcode scanner 385 may be an integral part of themedical cart 500 or may be detachable therefrom. If thebarcode scanner 385 is an integral component of themedical cart 500, itspower cord 387 may be inserted into apower cord passage 327 and connected to anelectrical receptacle 904, as later explained in detail with respect to FIGS. 11-13. By way of contrast, thebarcode scanner 385 may receive the power necessary to operate it from alaptop computer 900 when it is plugged into a USB port of thelaptop computer 900. - As shown in FIGS. 6A-6C, the
adjustable clipboard 390 is also designed to hold items in a hands-free manner. Theclipboard 390 includes aclip 392 for holding items, such as paper. Theclipboard 390 also includesconventional rails 394 attached to an L-shapedmetal bracket 393 which connects theclipboard 390 to thelaptop platform 370, as shown best in FIG. 6C. Theclipboard 390 is designed to slide along therails 394 to the left of themedical cart 500. As a result, if a user is working on a laptop computer provided on thelaptop platform 370, theclipboard 390 can be moved from a central position (FIG. 6B) to left of the laptop computer to allow the user to view the documents clipped to theclip 392, as shown in FIGS. 6A and 6C. Of course, in other embodiments, theclipboard 390 could be designed to move to the right. - The plurality of
compartments 530 face the user and move up and down with the work platform 340 (i.e., they remain in the same position relative to the laptop platform 370), which are ergonomically desirable features. Thecompartments 530 may be provided withlabeling portions 570, which allow labels to be displayed on thecompartments 530. The plurality ofcompartments 530 enable a user (e.g., a nurse) to separately maintain medication for particular patients or for a particular room. For example, if a nurse is responsible for eight patients in a hospital ward, themedical cart 500 may be provided with a corresponding number ofcompartments 530 and the medication for each patient may be kept in a separate drawer assigned to that patient. As a result, the nurse could load the medication for all eight patients into eight separate drawers at one time (e.g., at the start of a medication pass) and at one location (e.g., at a pyxis machine), thereby reducing the need to travel to obtain the medication during the nurse's shift. - As shown in FIGS. 7 and 8, the
compartments 530 haveprojections 531 which are configured to slide ingrooves 533 formed on the interior walls of themedical cart 500. Although thecompartments 530 in FIG. 1 are shown as having a generally uniform height, this is not required. In some embodiments thecompartments 530 may have different heights. - For example, as shown in FIG. 7, four
short compartments 530A-D can be removed, thereby exposing dividers 535 (which may be, for example, sheet metal). By removing the dividers 535 (e.g., by sliding them out of the medical cart 500), as shown in the left side of themedical cart 500 in FIG. 7, atall space 537 may be created. As a result, atall compartment 530E, the height of which is substantially equal to height of the fourshort compartments 530A-D when installed in themedical cart 500, may be inserted intomedication module 500 to substantially fill thespace 537. Moreover, thetall compartment 530E will readily slide into themedical cart 500 by means of theprojections 531 which are configured to slide into thegrooves 533 previously occupied by theprojections 531 of the uppershort compartment 530A. Thus,different size compartments 530 can be accommodated based on the desired application. - The
compartments 530 may be lockable by means of a keyless entry system (the details of which are later described with respect to FIGS. 22 and 23). Thus, the potential for unauthorized access to thecompartments 530 while the nurse is caring for a particular patient is small. - The top bins243 are provided to house items such as paperclips, pencils, etc. Similarly, the
cup holders 344 are provided to secure a number of medicine cups used to pass out medications. - The
removable side bins 520 can be provided to hold items, such as trash or medical equipment. Theside bins 520 can be removably connected to the sides of the body 329 of thework platform 340 by conventional means, such as a hole and pin arrangement. - The
work platform 340 may be raised and lowered by means of thesupport mechanism 320. This provides a sitting or standing user with easy access to thework surface 350 and its associated components (e.g.,laptop platform 370,work surface 350,compartments 530, etc.). Thesupport mechanism 320 allows the user to adjust the position of thework platform 340 to a comfortable position, regardless of whether the user is sitting or standing. Thesupport mechanism 320 comprises twotelescoping portions 322, 324 (shown more clearly in the embodiment shown in FIG. 16) and height adjustment mechanism 400 (shown in FIGS. 9A and 9B). Theheight adjustment mechanism 400 enables a standing user or a sitting user to ergonomically raise and lower thework platform 340. - The
height adjustment mechanism 400 includes anouter casing 410, a telescopinginner casing 420, and adriver 430. Preferably, two or more drawer slides 422 are provided between theinner casing 420 and theouter casing 410. Although two drawer slides 422 may be used (on opposite sides of the inner casing 420), it is preferable to use at least three drawer slides 422, to prevent (or at least greatly inhibit) a binding action from being applied to theheight adjustment mechanism 400 by means of a cantilevered force being applied thereto. - The drawer slides422 may be, for example, conventional drawer rails formed of stationary drawer rails 423 and corresponding rail runners 425. If the drawer slides 422 are conventional drawer rails, one side of the drawer slides 422 (e.g., the rail runners 425) may be fixed to outer sides of the
inner casing 420 and the corresponding side of the drawer slides 422 (e.g., the stationary drawer rails 423) may be fixed to inner sides theouter casing 420. Further, the stationary drawer rails 423 may be provided with ball bearings to facilitate movement of the rail runner 425. An upper end of one side of theinner casing 420 is provided with anengagement mechanism 426. As shown, the engagement mechanism may be in the form of a window in the side of thecasing 420. - The
driver 430 includes a gas drivenpiston 432 which, in turn, includes abody portion 436 and atelescoping strut 434. Thedriver 430 is controlled by anactuator 440 to which is connected by aconnector 442. - As shown in FIG. 10A, a
base 411 of theouter casing 410 is affixed to thebase 310 of themedical cart 500 by a plurality of bolts through thebase 411. Abolt 413 passes through ahole 437 in aconnection portion 439 of thebody portion 436 of thepiston 432, thereby immobilizing both theouter casing 410 and thepiston 432. In addition, as shown in FIG. 10B, theinner casing 420 and thetelescoping strut 434 are affixed to workplatform 340 by anupper bolt 415 which passes through theinner casing 420 and through ahole 459 in aconnection portion 460 of thetelescoping strut 434. As a result, when thework platform 340 is raised or lowered, thestrut 434 and theinner casing 420 are correspondingly raised or lowered. - As shown in FIG. 10B, the
actuator 440 may be provided in a front portion of themedical cart 500. Moreover, abutton 444 of theactuator 440 may be provided in thehandle 360 of themedical cart 500, as shown in FIG. 1. To lower thework platform 340, thebutton 444 is pushed as a user pushes down onwork platform 340 thereby causing the gas drivenpiston 432 to expel air. As a result, thetelescoping strut 434 is withdrawn vertically into thebody portion 436 of thepiston 432. As thetelescoping strut 434 moves downward into thebody portion 436, thework platform 340 which is affixed to thetelescoping strut 434 also moves downward. In turn, thework platform 340 forces theconnection portion 460 and theinner casing 420 to move downward. If thebutton 444 is released while thework platform 340 is being lowered, thework platform 340 will be releaseably locked at the height at which thebutton 444 is released. As a result, thework platform 340 can be releaseably locked at any position between a lowest position (at which thetelescoping strut 434 is maximally provided in thebody portion 436 of the piston 432) and a highest position (at which theinner casing 420 is driven upward to a maximum distance by thetelescoping strut 434 of the piston 432). - By way of contrast, to raise the
work platform 340, a user merely needs to pushbutton 444 and lift upward on thework platform 340. As thework platform 340 is light in weight, it will readily move upward. Moreover, in the process, the gas drivenpiston 432 will intake air, thereby enabling thework platform 340 to remain at the raised level, i.e., when theplatform 340 is raised gas will be sucked into thepiston 340 and will not be readily expellable until thebutton 444 is depressed. In other words, similar to the process of lowering thework platform 340, when thework platform 340 is raised it may be releaseably locked at any position between the lowest position and the height position by releasing thebutton 444. As a result, each component of the work platform 340 (including thebi-directional laptop platform 370 and the compartments 530) is ergonomically available to a user when sitting or standing. - In addition, as shown in FIGS. 12 and 13, the medical cart can include a
power cord passage 327 that enables apower cord 902 of a laptop computer 900 (or other device) on thelaptop platform 370 to be electrically connected to anelectrical receptacle 904 provided in thebase 310. Theelectrical receptacle 904 can be connected, for example to a wall outlet via aretractable cord 906, as later described. Preferably, thepassage 327 includes anaccess hole 325 in thework platform 340 and extends through thetelescoping portions passage 327 terminates in a well 960 in the base 310 where the electrical connection can occur. This permits the point of connection to theelectrical receptacle 904 to be enclosed. - As shown in FIG. 13, the well960 in the base 310 houses the
electrical receptacle 904, aretractable cord 906, and ahatch 908 that provides access to the well 960 so thatpower cords electrical receptacle 904. Theretractable cord 906 can be plugged into an external wall outlet to recharge the battery internal to thelaptop computer 900 and/or a battery-poweredsolenoid 240 in the keyless entry system (later described in detail). Thehatch 908 works in conjunction with acover plate 910 to enclose the base 310 including the well 960, thereby encapsulating the components provided in thebase 310 and shielding them from the environment. - The
base 310, which is moveable by means of rolling members 120 (e.g., casters), is ergonomically shaped to provide stability. Thebase 310 is designed to provide stability by having the rollingmembers 120 at corners which are outside of the footprint of thework platform 340. Moreover, the rollingmembers 120 are spaced-apart to such a degree that two rollingmembers 123 of amedication module 100 can be located between two rollingmembers 121 of thebase 310, thereby enabling themedical cart 500 and themedication module 100 to nest together. Further, when themedical cart 500 is nested with amedication module 100, it may be releaseably connected to themedication module 100 by means of asecond locking mechanism 190 provided on an underside of the base 310 (shown in FIGS. 1 and 15), also as later described in detail. - Another embodiment of a
medical cart 300 is shown in FIG. 16. In this embodiment, theremovable side bins 520 of theprevious cart 500 have been removed to facilitate joining themedical cart 300 with amedication module 100. Themedical cart 300, like themedical cart 500 shown in FIG. 1, also includes asecond locking mechanism 190 which may be used to connect themedical cart 300 to amedication module 100. In addition, thecart 300 containsfewer compartments 330 which may, like thecompartments 530 of themedical cart 500 shown in FIG. 1, be lockable by means of a keyless entry system or by a conventional key lock. - One embodiment of a
medication module 100, which may be referred to as a cart, is shown in FIGS. 17-23. As shown in FIG. 17, themedication module 100 includes a component body 111 having a plurality oflockable compartments 130 and which is supported by abase 110. The medication module also may include arefuse container 140, adepression work surface 150, a retractable power cord 144 (shown best in FIGS. 18 and 21B) which can be used to recharge abattery 241 of akeyless entry system 600 by means of a power cord 233 (as later described in detail), afront handle 160, and aside handle 162. The two handles 160, 162 are provided so that the medication module can be pushed by a user standing in front of thecompartments 130 or in front of thesidewall 112. - The component body111 includes two
side walls 112 and aback wall 114. Thewalls compartments 130 which, for example, may be in the form of drawers. Although thecompartments 130 are shown as having a generally uniform height, this is not required. Moreover, in some embodiments thecompartments 130 may have different heights. As a result, a plurality ofshort compartments 130 may be replaced by atall compartment 130 in the manner previously described with respect to the firstmedical cart 500 embodiment. - It is preferable to provide the user with the ability to lock the
compartments 130, of themedication module 100. To reduce the likelihood of losing a key, to reduce the likelihood of having a key getting stuck (or worse broken) in a lock, and to eliminate the need for a separate lock for eachcompartment 130, the compartments may be lockable by akeyless entry system 600, as hereafter described with respect to FIGS. 22 and 23. - The
keyless entry system 600 includes a solenoid 240 (powered by abattery 241 which is electrically connected, by means of thepower cord 233, to the retractable power cord 144), a printed circuit board (“PCB”) 245, apiston 222, a spring-biased hinge 210 (which has anactive side 211 and a stationary side 213), akeypad 238, and anactuating lever 224 which is connected to thepiston 222 at aconnection point 231 and which pivots around an axis of rotation defined by apin 230. - The
hinge 210 can be, for example, a hinge conventionally known as a piano hinge. In a locked orientation, theactive side 211 of thehinge 210 is provided in anengagement position 215 in which theactive side 211 is positioned to engage anotch 132 formed on a compartment 130 (i.e., eachcompartment 130 has a similar notch 132), if a user attempts to withdraw thecompartment 130. In other words, as a result of the engagement between theactive side 211 of thespring 210 and thenotches 132 of thecompartments 130, thecompartments 130 can not be readily withdrawn out of themedication module 100. - To unlock the
compartments 130, a user first enters a security code using buttons of the keypad 238 (to verify access to the medication module 100) and may, if required, then enter an unlock code on thekeypad 238. In response, thePCB 245 sends an unlock signal to thesolenoid 240. When the unlock signal is received by thePCB 245, thesolenoid 240 withdraws thepiston 222, thereby causing the end of actuatinglever 224 in contact with theactive side 211 of thespring 210 to swing outward on thepin 230. As a result, theactuating lever 224 causes theactive side 211 of thespring 210 to swing out of theengagement position 215 and into adisengagement position 217. In other words, theactive side 211 swings toward thestationary side 213 of thespring 210 so that the twosides sides spring 210 rest against each other, thenotches 132 of thecompartments 130 will no longer be inhibited by theactive side 211 of thespring 210. As a result, thecompartments 130 may be readily removed from themedication module 100. - The
compartments 130 can be relocked by pressing a “lock” button (not labeled) on thekeypad 238 or by entering a lock code on thekeypad 238; in either case, thePCB 245 will send a lock signal to thesolenoid 240 instructing it to outwardly push thepiston 222, thereby causing the end of theactuating lever 224 in contact with theactive side 211 of thespring 210 to swing inward on thepin 230. As a result, theactive side 211 of thespring 210 will swing back into theengagement position 215 by means of the spring-biased nature of thespring 210. In addition, and as a safety means, a timer may be provided in thekeypad 238,PCB 245, or in thesolenoid 240 which will, when a timer count is satisfied, automatically instruct thepiston 222 to be outwardly pushed, thereby causing theactive side 211 of thespring 210 to retract into theengagement position 215. - If a
compartment 130 is removed when either a lock signal is sent to thesolenoid 240 or when a timer count is satisfied (and theactive side 211 of thespring 210 is provided in the engagement position 215), thecompartment 130 may be inserted into the medication module without entering an unlock code. Specifically, thenotches 132 of thecompartments 130 have slopedfaces 133 thereon which, when thecompartment 130 is pushed into themedication module 100, will abut theactive side 211 of thespring 210. By continuing to push thecompartment 130, the slopedface 133 will cause theactive side 211 of thespring 210 to collapse into thedisengagement position 217, i.e., the spring-bias of thespring 210 will be overcome. After thesloped face 133 passes the active side of thespring 210, theactive side 211 will snap back into the engagement position 215 (by means of the spring-bias), thereby locking thecompartment 130 in themedication module 100. - An additional safety (and access) measure may be provided to address a situation in which the
keypad 238 fails or the battery poweredsolenoid 240 loses power. Specifically, thecompartments 130 may be unlocked manually by a hard (back-up)lock 220, as shown in FIGS. 17 and 23. By means of thehard lock 220, a key can be used to manually rotate theactuating lever 224, thereby pushing theactive side 211 of thespring 210 or enabling it to swing outward under the force of the spring bias. In other words, the key can be used to move theactive side 211 manually out of theengagement position 215 or to allow theactive side 211 to swing (under the spring-biased force) into theengagement position 215. - Although the
keyless entry system 600 has been described with respect to themedication module 100, thesame system 600 can be applied to thecompartments medical carts - As a result of the ability to lock the
compartments medication module 100 and/ormedical cart compartments keypad 238, a nurse does not have to worry about losing a key, except for the hard lock key which may be kept at a central location. - The
base 110, which is supported by a plurality of rolling members 120 (e.g., casters), is designed to provide stability to the frame 111, similar to thebase 310 of themedical cart base 110 is also designed such that the two of the rollingmembers 121 on one side of themodule 100 are spaced apart farther than the two rollingmembers 123 on the other side of themodule 100. As a result, when two medication modules 100 (or amedication module 100 and amedical cart 300, 500) are brought together, the closer spaced rollingmembers 123 of onemodule 100 can fit between the farther spaced rollingmembers 121 of the other module 100 (ormedical cart 300, 500), thereby enabling the modules 100 (ormodule 100 andmedical cart 300, 500) to nest closer together to form atrain 200. - As a result of the ability to nest the
bases 110 of a plurality ofconsecutive medication modules 100 in a train 200 (as later described in detail), thesidewalls adjacent modules 100 can be positioned in close proximity, thereby creating a small footprint for thetrain 200. Similarly, as a result of the ability to nest thebase 110 of amedication module 100 and thebase 310 of amedical carts medication module 100 can be in close proximity to thework platform 340 of themedical cart - To releaseably link the nested medication modules100 (or a
medication module 100 and nested amedical cart 300, 500), thebase 110 of themedication module 100 is provided with aconnection mechanism 171. Theconnection mechanism 171 includes anactuator 180, afirst locking mechanism 170, and asecond locking mechanism 190, as best shown in FIGS. 19 and 20. Theactuator 180, which may be in the form of a foot pedal, includes apivot rod 182. When thefoot pedal 180 is depressed, thepivot rod 182 is configured to rotate withinrings 192 from a resting position to an active position, thereby activating thefirst locking mechanism 170. - The
first locking mechanism 170 includesbeams 188,cover plates 186 having slopedsurfaces 194, and catches 184 which comprisecavities 187. When therod 182 of theactuator 180 rotates, it pulls thebeams 188 toward the center of thebase 110. In turn, thebeams 188 cause thecover plates 186 to rotate toward the center of thebase 110. As thecover plates 186 rotate, they expose thecavities 187 in thecatches 184. Correspondingly, when theactuator 180 is released, therod 182 rotates back to the resting position, thereby pushing thebeams 188 away from the center of thebase 110 and, in turn, rotating thecover plates 186 to enclose thecavities 187. - When the
cavities 187 are closed, they are designed to releaseably containposts 197 of asecond locking mechanism 190 of anothermedication module 100 or of amedical cart posts 197 may be provided separately on thebase medication module 100 andmedical carts crossbar 196. Regardless of the design of theposts 197, they enable amedication module 100 to be joined to anothermedication module 100 to form atrain 200, as shown in FIG. 20. - A
train 200 ofmedication modules 100A-100C can be formed by releaseably aligning theposts 197 of asecond locking mechanism 190 of onemedication module 100A with thecover plates 186 of afirst locking mechanism 170 of anadjacent medication module 100B. By pushing themodules posts 197 will slide along the slopedsurfaces 194 of thecover plates 186, thereby causing thecover plates 186 to rotate. As thecover plates 186 rotate, thecavities 187 will be exposed and theposts 197 will slide into them. After theposts 197 slide into thecavities 187, thecover plates 186 will retract, thereby locking theposts 197 in the cavities. Of course, to add athird medication module 100C, theposts 197 of thesecond medication module 100B would be similarly inserted into thecavities 187 of thethird medication module 100C. - As the
medical carts second locking mechanisms 190, the medication module can be releaseably joined with themedical carts medication module 100 can be releaseably joined with themedical cart 300 shown in FIG. 16. Of course, to release themedication module 100 from themedical carts first locking mechanism 170 formed under thebase 110 of themedication module 100 and thesecond locking mechanism 190 formed under thebase 310 of themedical cart - As shown in FIG. 24, a
train 200 ofmedication modules 100 can be loaded with medication at a central location (e.g., pharmacy) 700; the number ofmedication modules 100 may depend on the number ofmedical carts train 200 to asecond location 800 at which theindividual medication modules 100 can be separated from thetrain 200. In addition, themedication modules 100 may be joined (by means of thefirst connection mechanism 171 thereon) to amedical cart 300, 500 (by means of thesecond locking mechanism 190 thereon). One ormore nurses 750 can then drive the separated medication modules 100 (with or without amedical cart empty medication modules 100 can be separated from attachedmedical carts 300, 500 (if any) and rejoined to form atrain 200 ofmedication modules 100. Thetrain 200 ofmedication modules 100 may then be returned to thecentral location 700 for refilling so that the method of medication transport may be repeated. - Similar to the aforementioned method, a modification may be made.
