HOSPITAL PATIENT CARE UNIT
Abstract
A hospital patient care unit is provided which consists of a
folding toilet in a compact cabinet wherein the bowl of the toilet
is removable so that the unit can be used either as a bedpan or in
the normal manner. The unit is designed so that when it is closed,
the bowl is automatically flushed and washed out and an interlock
prevents opening the cabinet while the flushing operation is taking
place.

Claims
I claim:
1. A hospital care unit comprising in combination:
a. a cabinet,
b. a door on said cabinet, said door having a horizontal hinge at
the bottom thereof,
c. a stop mounted between said cabinet and said door whereby said
door can be opened outwardly and held in a horizontal position and
folded upwardly into said cabinet into a vertical position wherein
said door is flush with the front wall of said cabinet,
d. a toilet seat hinged on said door by a bracket extending
upwardly from said door whereby said toilet seat is spaced from
said door and can be swung to a horizontal position or to a
vertical position while said door is in the horizontal
position,
e. clamp means on said door, and
f. a bedpan unit removably held by said clamp means whereby said
bedpan can be used as a normal toilet or separated and used as a
toilet elsewhere.
2. The patient care unit of claim 1 wherein flushing means is
provided within said cabinet, said means being actuated by closing
the door of the toilet unit.
3. The hospital patient care unit of claim 2 wherein an interlock
is provided whereby said door is locked in the closed position
while the unit is being flushed.
Description
SUMMARY OF THE INVENTION
The present invention relates to a hospital care unit which
consists of a toilet which folds into a cabinet. The bowl portion
of the toilet can be removed and used separately as a bedpan. When
the bowl is in position the cabinet can be closed whereupon the
unit automatically flushes and washes out the bedpan. An automatic
interlock prevents opening the cabinet while the flushing operation
is taking place.
The unit is very compact and in a preferred embodiment of the
invention extends outwardly only one foot from the wall on which
the unit is mounted while the cabinet is in the closed
position.
It is relatively inexpensive and encourages patients to take care
of their own needs as early as possible and minimizes personnel
work load.
In coronary care rooms a patient is wired to wall mounted
instruments near his bed. As his condition improves he is
encouraged to become ambulatory and the proximity of the HPC unit
to his bed permits use of the unit as a toilet.
The unit lends itself to being combined with a lavatory so that all
of a room's plumbing needs can be taken care of in one compact
unit. Since the bowl or convenience receptacle is removable, it
lends itself to ready use for stool examination and provides a
simple means for measuring a patient's output in coronary care
rooms where the intake and output is important to diagnosis and
treatment. The convenience receptacle is preferably formed of
stainless steel and is easily sterilizable.
The cabinet itself has removable access panels so it is easy for
plumbing hookup and maintenance operation.
The unit is designed for use with a standard flush valve so that
special parts or fittings are unnecessary and maintenance parts are
readily available.
The patient care unit of the present invention has a number of
other advantages over structures proposed in the past and these
additional advantages will be brought out in the balance of the
specification.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a patient care unit embodying the
present invention showing it in the open position.
FIG. 2 is a side view of the unit shown in FIG. 1, partly in
section.
FIG. 3 is a front view on the line 3--3 of FIG. 2.
FIG. 4 is an enlarged sectional view on the line 4--4 of FIG. 3 of
the interlock which prevents opening the unit while the flushing
operation is taking place.
FIG. 5 is a piping diagram of the flushing unit.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings by reference characters, the unit of
the present invention is housed in a cabinet having a front panel
5, with access panels 6 and 8. The cabinet also includes side
panels 7 and 9 and a top work surface 11. The top surface 11 may be
provided with the usual lavatory fittings, including a washbowl,
all generally designated 13. At the front of the cabinet an opening
15 is provided and near the bottom of this opening a support member
17 is mounted by means of a hinge 19 with spring loaded hinge pin
20 to permit removal for thorough cleaning. Support unit 17 is
mounted in such a manner that when it is in a closed position it
will lie flush with the front panel 5 and thus forms a door.
Uprights 21 support a toilet seat 23 which is provided with the
usual hinge mounting 25. A bedpan or convenience receptacle 27,
preferably formed from two pieces of stainless steel, is provided
which rests on the support frame 17 and is held in position by pins
29 and the support arms 21. Receptacle 27 is not fastened down so
that it is readily removed for use in another location, yet is held
in the desired place by the means described. At the front of
support member 17 a hole 31 is provided which serves to lock the
support member in the upright or closed position while the flushing
action is taking place as is hereinafter described in detail.
Mounted within the cabinet is a standard flush valve 33 which is
connected by suitable piping 35 through stop valve 36 to a water
source, not shown. The flush valve includes the usual pushbutton 37
which is actuated by pressure from the toilet seat 23 when it is in
the upright position as is best seen in dot dash lines in FIG. 2. A
first pipe 39 leads from the flush valve through a vacuum breaker
40 to a central nozzle 41 and bottom nozzles 43 and 45 which squirt
against the convenience receptacle thoroughly flushing it and
washing the contents down the drain. To further assist in the
flushing operation, a nozzle 47 is provided in trap 49 so that any
solid matter is positively washed from the trap. The top of the
trap 49 is enlarged as at 51 for the reception of the material from
the convenience unit. Another line 53 leads from flush valve 33 to
interlock 55. Interlock 55 consists of a cylinder 57, having a
piston 59 mounted for reciprocation therein, the piston being
normally held in the up position by a spring 61. A pin 63 extends
downwardly from piston 59 and when water pressure is applied
through line 53, pin 63 is driven downwardly into the hole 31,
positively locking support member 17 in the closed position. This
prevents any splashing from the unit which might result in soiling
the clothes of a person who actuated the flushing operation. After
the flushing operation is complete, the pressure falls in line 53,
allowing pin 63 to move upardly, releasing the support member 17 so
the unit is now ready for a repetition of the operation.
It is believed apparent from the foregoing that I have provided a
hospital patient care unit which occupies little space, which is
simple in construction and which can be used as an ordinary toilet
or as a flushing unit for a bed pan.
