SHEU2BF2 INVENTOR Josey/2 D. J/zaw PROGRAMMED DISPENSER This is a continuation of application Ser. No. 99,165 filed Dec. I7, 1970 now abandoned.
The present invention relates to a programmed dispenser and particularly to a time coded cabinet device for dispensing medication which is best suited for use in hospitals whose personnel dispense large quantities of different medication to many different patients at irregular time intervals during a day or throughout a series of days.
It is the primary object of the invention to provide a prescribed medicinal dispenser that is portable between a hospital pharmacy and the ward nursing station therefor and which will serve as a positive medication dispensing reminder of the administration time and the prescribed dosage of medication for each of a plurality of patients being cared for in that particular hospital ward.
Another object of the invention is to provide a portable medicine cabinet with sliding drawers containing pharmaceuticals which will positively control the dispensation of said medicinals to the proper patients by means which when periodically operated will indicate to the hospital attendant at the proper time the pharmaceuticals to be disbursed to particular patients.
A further object of the invention is to provide in a multidrawer cabinet a time coding means for each drawer in combination with a decoding case which cooperates with the cabinet to present at a particular time all the individual pharmaceutical containing drawers to be dispensed at that time.
With the foregoing and other objects in view, my invention consists in the construction, arrangement, and combination of elements as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:
FIG. 1 is a perspective view of the programmed dispensing device of this invention with its cooperating parts in non-dispensing positions, certain wall portions being broken away and shown in section.
FIG. 2 is a fragmental, rear elevational view of the cabinet part of the device with the coded drawers held therein.
FIG. 3 is an enlarged section taken laterally through the device with its parts in decoded dispensing positions.
FIG. 4 is a fragmental, elevational view of the selector board for the device shown in FIGS. 1-3 of the drawings.
FIG. 5 is a greatly enlarged section showing a detail of my device.
FIG. 6 is an enlarged section like FIG. 3 showing a modification of my dispensing device.
FIG. 7 is a greatly enlarged section showing a detail of the drawer structure for the device shown in FIG. 6.
Many pharmaceuticals are prescribed for each of a number of hospital patients in a ward for periodic dispensation in uniform amounts and this presents a distribution control problem to both the pharmacist and to the attendants at the ward s nursing station. In the embodiment of the invention shown in FIGS. 1-5 of the drawings, my programmed dispenser is represented as a conventional, rectangular cabinet 10 preferably small enough to be readily portable by hand and having a number of compartments 1] arranged in both horizontal and vertical rows within the cabinet. Each compartment is adapted to slidably receive a drawer 12 having the usual hand pull l3 and a front wall 14 carrying an index frame 15. The frame is adapted to removably hold an identification card displaying, for example, the name of a patient, his or her hospital room number, the identification of the drug contained in the drawer and other data relating to the administration of and the recipient of the particular pharmaceutical. As best shown in FIG. 2 the rear of the cabinet is open, except for a marginal flange 16, and interconnected vertical flanges 17 which form rear stops for the drawers 12 in the cabinet.
Each drawer has a lateral wall such as a back wall 18 having two lateral rows of holes 19 and 20 formed therethrough, the holes in each row being preferably equally spaced apart and preferably numbering twelve (12) holes to the row. lndicia are marked on the back of each drawer (FIG. 2) to identify one row 19 of holes as pertaining to the AM hours of the day while the other row 20 has indicia thereon identifying it with the PM hours of a day. It will also be noted that the horizontal row of AM holes 19 are closer to the top of the drawer back than are the PM row 20 of holes with respect to the bottom of the drawer, for the purpose to be described hereinafter.
With reference to FIG. 3 of the drawings, it should be noted that each drawer has a lateral divider 21 near the rear wall 18 to provide a clearance space 22 and a pharmaceutical containing space 23 for the drawer.
The cabinet 10 with all its drawers 12 in their closed positions shown in FIG. 1 is adapted to be entered into a decoding case 24, said case having internal dimensions adapted to snugly and slidably receive the external dimensions of the cabinet. A side wall 25 of the case 24 has a vertical slot 26 formed in its rear portion for the reception of a laterally slidable, selector board 27. As best shown in FIGS. 1 and 4 the board 27 has a number of pins 28 projecting at right angles from one major face thereof, said pins being arranged in horizontal and vertical rows corresponding to similar rows of drawers held in the cabinet with preferably one pin assigned to each drawer. The selector board 27 is adapted for controlled, intermittent lateral movement across the inside rear portion of the case by an indexing means shown in FIG. 5 as a spring detent 29 mounted in the comer of the case adjacent the bottom end of the slot 26. The spring detent alternately cooperates with a row of twelve (12) teeth 30 or 31 each formed in a longitudinal edge 32 and 33, respectively, of the board adjacent diagonally opposed corners therein. The teeth in each row are spaced apart in regular increments corresponding to the spaces between the holes in the rows 19 and 20 through the back walls of the drawers so that when the board is moved laterally one tooth, the pins 28 in the board will be advanced one hole in the rows in their respective drawers.
As best shown in FIG. 4 of the drawings, the edge 33 of the board 27 opposed to the teeth 30 is provided with 12 calibrations 34 corresponding to the AM hours of the day while the longitudinal edge 32 of the board opposed to the teeth 31 is provided with calibrations 35 corresponding to the PM hours of a day.
The board is adapted to be turned longitudinal edgefor-longitudinal edge for alternate entry into the slot 26 and to this end a pair of entrance slots 36 (FIG. 1) is provided for each horizontal row of pins 28 as each row will be entered at different levels when the board is turned edge-for-edge within the casing.
As best shown in FIG. 3 a particular drawer is time coded by means of a plug 37 removably mounted in a particular hole or holes in the AM and/or PM rows 19 or 20, respectively, of the drawer.
In operation an identification card is made out for each patient in a particular room of a ward served by a nursing station, including the pharmaceutical and the time or times of administering it. A pharmacist places the identification card in the index frame of each drawer and then places the prescribed number of a given pharmaceutical in the drawer and codes the particular drawer for the time or times of administering said pharmaceuticalby inserting plugs in the coding rows 19 and 20 of the drawer at the proper indicated places. A cabinet thus prepared with a plurality of drawers therein is taken to the nursing station and an attendant at the station will then operate .the selector board 27 at each hour of the day by referring the AM or PM calibrations with the edge of the slot 26, the detent means positively locating the board at the proper lateral space for the pins to enter corresponding holes in the drawers. The cabinet is then slid into the case 24 and if a particular pharmaceutical is to be administered to a particular patient at the coded time a pin 28 will contact a plug 37 and push the drawer forwardly to an open position on the cabinet thereby visibly indicating to the attendant that the drug in that opened drawer is to be administered to the named patient from that drawer. In the event a drug is not to be administered at that selected hour the pin will merely enter an unplugged hole in the drawer and the said drawer will remain unmoved and closed in the cabinet.
With reference to FIGS. 6 and 7 of the drawings, a modification of my device is illustrated wherein the selector device comprises a pin 38 insertable into one of the lateral rows of holes formed in the back walls of the drawers that are identical to the rows of holes 19 and 20 in the drawers of the preferred device. These pins when contacted by a pin 28 on the selector board 27 will push the drawer l2 forwardly to an opened position indicating that pharmaceuticals therein are to be dispensed at the particular hour at which the board is manually set. It will be noted that the pin 38 in the lowermost drawer 12 is longer than the pins shown in the two uppermost drawers which adapts it to move the drawer farther out of the cabinet to thereby indicate to the attendant that a different pharmaceutical dosage, or the like,'is to be administered from that drawer at that time. It will be noted that the drawers 12 shown in FIG. 6 have hinged covers 39 and that the drawer pulls 13 are formed on the forward ends of said covers. The preferred hinge forthe covers 39 is shown best in FIG. 7 wherein a cylindrical ball portion 40 formed on the cover is receivable in a socket 41 formed in the drawer back wall.
The AM position of the decoding board 27 is illustrated in full lines in FIG. 6 while the dotted lines shown the inverted PM positions of the decoding board and drawers from the same decoding position of the selector board in the case 24.
Although my programmed dispenser has been shown and described herein as it pertains to the administration of pharmaceuticals in hospitals it is contemplated that the dispenser could be used to program the performance of surgical operations with the proper instruments contained in the coded drawers or the dispenser could be useful in certain manufacturing processes requiring operational increments and the dispensation of large quantities of different items to different stations, or the like. In some instances the prescribed medication is kept in a locked separate cabinet and in such cases the front wall 14 of a programmed drawer 12 (FIG. 6) could be provided with a hook 42 to removably hold a key 43 that will unlock the separate cabinet 7 for access to the prescribed medication.
