RELATED APPLICATION
This is a continuation-in-part application of our co-pending
application for "Medicine Tray for Cabinet Drawer", Ser. No.
109,823, filed Jan. 26, 1971, now U.S. Pat. No. 3,708,709.
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 medicine to 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 nurse's 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-supporting so that it can be
removed from the drawer, but also provides the necessary retaining
means for the patient and needle trays.
Claims
We claim:
1. In combination, a mobile cabinet having a plurality of lockable
drawers; a removable plastic liner tray received in each of said
drawers and having integral perimetric side walls and a bottom
wall, said tray being elongated in a first direction and including
a plurality of parallel ribs in the bottom thereof, extending
across the width of said tray and spaced apart to receive a
plurality of patient trays in side-by-side relation; and a
plurality of individual patient trays having a generally
rectangular horizontal cross section with rounded corners and each
adapted to be received within said sections of said liner tray to
rest on the bottom thereof, each patient tray having a bottom,
three upright side walls and an inclined side wall extending
upwardly and outwardly from the bottom thereof and located adjacent
a narrow rib when said patient trays are placed side by side in
said sections of said liner tray to facilitate removal of said
patient trays by rotation about the lower edge of the side wall
opposing said inclined side wall without interfering with one of
said ribs or an adjacent patient tray, each patient tray further
including an upwardly and outwardly projecting flange forming a
finger grip at the upper edge of the inclined side wall thereof to
facilitate grasping of said tray when a plurality of said patient
trays are aligned within said sections of said plastic liner tray.
Description
Other features and advantages of the present invention will be
apparent to persons skilled in the art from the following detailed
description of a preferred embodiment accompanied by the attached
drawing wherein identical reference numerals will refer to like
parts in the various views.

section being taken at line 9--9 of FIGS. 4 and 11 and showing the
back half of the empty tray;

showing the patient identification card in the card holder and the
pill dosage dividers in place;
FIG. 11, a top plan view of the empty patient tray;

showing only patient trays in the liner tray; and
FIG. 14 is a cross sectional view taken transversely of the patient
trays showing the removal of the patient trays from a liner
tray.
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 upwardly-raised
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 21, 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 a 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, and 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 upwardly and outwardly inclined, as
illustrated; and it is provided at its top edge with a finger grip
33 which 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.
Referring now to FIG. 14, it can be seen that the finger grip or
handle is easily accessible by a person even though the trays are
in closely stacked relation so as to conserve space. Further, a
person does not obscure the reading of the patient cards held in
the holder 35 while removing one of the patient trays 25. It will
also be observed that the inclination of the oblique wall 32
facilitates removal of a patient tray by rotation about the
diagonally opposite lower edge, designated by reference numeral 50
in FIG. 14.
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.
Turning now to FIG. 13, there is shown a modification wherein the
liner is designated 23a, and it is provided only with the parallel
narrow ribs 27 so as to accommodate 24 separate patient trays 25,
identical to those already described. For certain operations, it is
desirable to use a liner such as this without having space for the
hypodermic needle trays, as previously disclosed.
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, and
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 patient's table or into the
patient's 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 germ-free 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.
