Wymon BYQDWAJZZJMQF'QM MEDICINE TRAY FOR CABINET DRAWER BACKGROUND AND SUMMARY In a hospital or nursing home, many types of medicine must be dispensed to many patients at intervals during the day and there is a great demand upon a nurse's time and accuracy in presenting the proper patient each time and without touching the pills or other medicine. We have discovered that a plastic liner can be provided for the nurses cart cabinet drawer and so fashioned and contoured as to provide support for patient and needle trays and wherein integral ribs in the structure not only make the thin plastic liner self-sup porting so that it can be removed from the drawer, but also provides the necessary retaining means for the patient and needle trays.

Detailed Description By way of general description, we have provided for use with a cabinet drawer a removable plastic liner tray having integral side walls and a bottom wall with raised ribs reinforcing the bottom wall and providing patient tray compartments, together with individual patient trays which fit within the compartments and having side wall ribs for retaining patient identification cards. The liner tray is also provided at one end with a needle tray having saw-toothed or V-shaped receptacles for receiving hypodermic needles, etc. The liner drawer structure may be formed from any suitable plastic, and preferably in a vacuum-drawing apparatus in which the plastic is drawn within a mold to provide upwardlyraised ribs that not only make the thin plastic bottom sturdy but also serve to hold or locate the patient and needle trays, etc. within the liner tray. The plastic may be a resin plastic, such as polyethylene or polypropylene, or any other suitable type of plastic.
Referring specifically to the drawings, the cabinet cart 20 has several prescription dispensing drawers 2], each with a key lock 22.
Each drawer has a plastic drawer liner tray 23 which holds one plastic hypodermic needle tray 24 and several individual plastic patient trays 25.
The drawer liner tray 23 has distorted bottom 26 which is raised in several places to form patient tray ribs or separations 27, a wide separation or rib 28 between the last row of patient trays 25 and the hypodermic needle tray 24, the two stops 29 to prevent the hypodermic tray 24 from sliding across the end of the liner tray 23 while the cabinet cart 20 is in motion.
The hypodermic tray 24 has a saw-tooth shaped bottom 30 with a slight flat portion 31 between each rise for easy cleaning. This drastically raised bottom portion 30 holds each hypodermic needle firmly, and prevents it from rolling and coming into contact with the others, which would cause confusion, if not damage.
The plastic individual patient tray 25 is rectangular in shape, making the best usage of the space allotted to it.
The right wall 32 is on an angle so that the tray can be removed diagonally from under the finger grip 33 of the tray on the left of it. The finger grip 33 is a projection of the right wall, and rises obliquely as it projects above the sides of the surrounding trays for easy gripping and raising. The back wall 34 of the tray 25 has two oblique projections 35 for holding the individual patient identification card 36. The tray also has three sets of projections 37 which serve as supports for holding a tray divider 38 in place.
As can be seen in FIGS. 5 through 12, all corners are slightly rounded which not only makes the trays easier to manufacture but makes them easier to keep clean.
By way of illustration, the specific plastic tray and cart structure shown may be used for 48 patients with the day's pill prescriptions for the patients counted out and placed in the 48 plastic patient trays, and 24 hypodermic needles can be filled and placed in three hypodermic trays at one time, thus filling the three drawers shown in FIGS. 1 and 2. The cabinet cart is ready to be pushed down the corridor for the distribution of the contents. The stops or ribs 30 prevent movement of the needles as the cart is pushed down the corridor, while the raised segments and side wall of the liner tray prevent sideway movement of the needle tray, an such sideway movement of the patient trays is also prevented by the raised ribs.
The patient trays have an inclined wall on one side so that the tray can be drawn over other trays and over the ribs, and the side wall is further extended to provide an oblique finger grip for the separation of the patient trays. With the rounded or inclined side wall and the finger grip, the nurse can readily slide the pill or other medication from the tray onto the patients table or into the patients hand. The identification card holder on each tray enables both the nurse and the patient to make sure that there is no mistake in the dispensing of the medicine.
With the plastic liner structure, the medication prescriptions can be made up and the trays locked inside the cabinet until time for dispensing them, while also keeping the medication dust-free and in a germfree environment. The patient tray can be divided into separate compartments when it is desired by the use of the dividers and the retainer ribs on the sides of the tray, and the resilient plastic material prevents breaking or chipping if the tray should be accidentally dropped, etc. The light plastic liner tray can be readily removed for filling and for any other use, and the raised rib structure provided renders the relatively large tray self-supporting and useful as a carrier of the contents.
While in the foregoing specification we have set out specific structure in considerable detail for the purpose of illustrating embodiments of the invention, it will be understood that such details may be varied widely by those skilled in the art without departing from the spirit of our invention.
1. In combination, a removable plastic liner tray adapted to be received in a cabinet drawer and having integral parametric side walls and a bottom wall, said tray being elongated in a first direction and including a relatively wide separating ribs dividing said liner tray into a first compartment having a plurality of sections adapted to receive patient trays and a second compartment adapted to receive a hypodermic needle tray, said bottom further including first and second raised ribs extending transverse of said relatively wide first rib and placed to engage the bottom of a hypodermic tray and to prevent the same from sliding when a hypodermic tray is received in said second compartment, and a plurality of laterally spaced relatively thin second ribs extending transverse of the direction of elongation of said liner tray and spaced laterally apart to provide said plurality of sections for receiving patient trays; a plastic hypodermic needle tray having an integral serrated bottom providing a plurality of adjacent troughs for receiving hypodermic needles having a saw-tooth shape and cross section, adjacent converging surfaces of said troughs being generally planar and spaced apart at the line of convergence; and a plurality of individual patient trays having a generally rectangular horizontal cross section and each adapted to be received within said sections of said first compartment to rest on the bottom thereof, each patient tray having an inclined side wall extending upwardly and outwardly from the bottom thereof and located adjacent a narrow rib when said patient tray is placed in said first compartment to facilitate removal of said patient tray by rotation about the lower edge of the side wall opposing said inclined side wall without interfering with one of said second ribs or an adjacent patient tray, each patient tray further including an upwardly and outwardly projecting flange forming a handle at the upper edge of the inclined wall thereof to facilitate graspin of said tray when a plurality of said patient trays are a lgned withln said sections of said first compartment of said plastic liner tray.
2. The combination of claim 1 wherein each of said patient trays further comprises interior side wall ribs for retaining a patient identification card; and a plurality of pairs of spaced integral ribs for receiving removable dividers for forming compartments within each patient tray.
