COLLAPSIBLE AND DISPOSABLE BEDPAN
Abstract
A bedpan is provided which is collapsible and may be disposable.
The two main components of the bedpan are a rigid seat which may be
sterilized, and a disposable waste receptacle. The waste receptacle
consists of an inflatable donut-shaped ring of flexible material,
and a membrane of the same material within the ring to retain the
waste. The disposable component is designed to facilitate
construction in either heat-sealed vinyl, or moulded rubber. The
bedpan may be conveniently positioned under the patient in its
collapsed state of approximately 1-inch height, inflated to usable
size, used, removed, emptied and washed, deflated and reused as
required. When no longer necessary, the flexible portion may be
detached and disposed of, and the rigid seat sterilized for reuse,
cooperating snap elements being provided to attach the seat to the
inflatable receptacle. The unit may be inflated by a hand- or
foot-operated pump, a compressed air supply, or a charged capsule,
either by a patient or by an attendant. An alternate construction
may consist of an integral seal and inflatable waste receptacle
using a throwaway liner in the receptacle.

Description
This invention relates to a collapsible bedpan which may be
disposable.
It is a principal object of the present invention to provide a
bedpan, which is collapsible and disposable, and such that it can
be inserted under the patient while in its collapsed form and
thereafter inflated to assume the usual height of a standard rigid
bedpan, wherein the collapsed height being about an inch in
thickness thereby provides more comfort for the patient and less
difficulty for the hospital attendant.
It is another object of this invention to provide a bedpan which is
in part disposable due to the inexpensive nature of the
construction.
It is another object of the present invention to provide a two-part
collapsible bedpan in which the parts can be separated and made
washable and at the same time reusable after having been washed and
sterilized, the rigid seat thereby being easily sterilized for
continuing hospital use.
It is another object of the invention to provide a collapsible
bedpan of generally donut shape, providing for a double wall
thickness in the bottom of a central opening and a rigid seat
attached to the top of the inflatable bottom with its opening in
alignment with the opening of the inflatable bottom part.
It is another object of the invention to provide a collapsible
bedpan which may have its own device for effecting the inflation of
the same at the will of the patient and by the mere puncturing of a
charged capsule for admitting the gas under pressure into the
inflatable bottom part of the bedpan to inflate the same.
It is still another object of the invention to provide a bedpan
which is flexible, has a cushionlike feeling, easy for mounting by
the patient, and in which the bedpan can be mounted without strain
from the patient and the patient lifted by effecting the inflation
of the bedpan.
Other objects of the invention are to provide a collapsible bedpan,
having the above objects in mind, which is of simple construction,
inexpensive to manufacture, has a minimum number of parts, easy to
assemble, easy to operate, easy to clean, sanitary, efficient and
effective in use.

Referring now particularly to FIGS. 1 to 5, 15 generally represents
a bedpan constructed according to the first form of the invention
which is comprised generally of an inflatable basin part 16 of more
or less donut shape, having a bottom 25 and a recess or central
space 18 for receiving fecal and urine discharges from a bedridden
patient and a rigid molded seat 19, having a central opening 21 to
be aligned with the space 18 of the basin and which is detachably
secured to the top of the inflatable basin 16 by snap-fastening
straps 22, each of which including a male snap element 23 adapted
to be attached to a corresponding female snap-fastening element 24
lying in the underside of the outer periphery of the molded seat
19.
The inflatable basin 16 is made from inflatable vinyl material
comprising a bottom part or piece 25, generally of ring shape and
serving as the bottom surface of the bedpan and on the top of which
there is secured by heat-sealing a differently shaped piece but
conforming generally to donut shape, this piece being indicated at
26, and having a bottom 27 that is spread flush with the bottom
piece 17 to provide a double thickness bottom for the space 18, and
which is heat-sealed about the periphery of the bottom portion 27,
and within the gas space 28 as at 29 to provide a gastight union
thereat and to maintain generally the donut-shaped gas space 28.
The bottom 27 of the upper part 26 may also be secured by
heat-sealing directly to the bottom part 17 to hold the parts in
the bottom of the space 18 in double thickness with one another.
After the heat-sealing has been effected at 29, the top vinyl
member 26 is welded to the bottom vinyl at the outer periphery of
the pieces 17 and 26 as indicated at 31.
There are four snap-fastener straps 22 secured to the inflatable
bottom basin 16, on opposite sides of the basin and
circumferentially spaced from one another there around for
immediately securing the seat 19 to the basin 16. After the bedpan
has been used, the seat 19 is detached from the basin part, the
basin part can be emptied of its contents, cleaned and washed and
made ready for reuse, or by replacing it with a new one.
The space 18 of the basin can be delivered compressed air or gas
through valve 32, as best seen in FIG. 1.
In use the bedpan can be placed under the patient having the shape
shown in FIG. 4, the height of the collapsed bedpan being probably
not more than 1 inch in thickness and which can be thereby placed
under the patient with less difficulty by the hospital staff and
with the patient being immobile or bedridden and thereby mounted on
the rigid top seat 19. Thereafter by applying a pump or some other
means for inflating the basin part 16, the bedpan can be restored
to its normal size and the patient lifted easily at the same time
to open up the collection contents space 18 and to provide thereby
a more or less normal-shaped bedpan, but at the same time providing
an air cushion feeling to the patient so that the patient can adapt
himself readily upon the bedpan and without need for centralizing
his weight thereupon as with a rigid-type solid metal bedpan now
generally in use in hospitals. Once the patient has used the bedpan
it can be removed as any other bedpan is removed from the patient
and in some instances it can be deflated, as when it can contain
nothing but urine, so that strain does not have to be placed upon
the back of the patient. The deflation is effected by opening the
one-way valve 32 and does not need to be total, but it may in some
instances even be collapsed to the same extent as the bedpan is
collapsed as shown in FIG. 4. Once the bedpan has been removed, the
straps 22 are pulled from the basin part to remove the rigid seat
19 and thereby permit the bottom part 16 to be emptied of its
contents and washed or sterilized either in its inflated shape or
collapsed shape.
Referring now particularly to FIGS. 6 to 12, there is shown a
second and modified form of the invention, in which 40 generally
represents the entire assembly comprising an inflatable bottom part
41, a rigid seat part 42 that is fixedly secured to the top of the
bottom part 41 and further including a gas cartridge puncturing
device assembly 44 connected by a rubber hose 43 with the
inflatable bottom part 41.
The bottom part 41 is constructed similarly to the bottom part 16
of the first mentioned form of the invention, but without a
peripheral heat-sealed flange connecting together two parts, but
being generally of donut shape and preferably made from a specially
prepared and shaped balloon member so as to provide upon completion
of the bottom part, one which is generally of donut shape. This
bottom part 41, being made of a closed member is finally shaped to
have a bottom portion 45, which serves as the bottom surface of the
bedpan and to the central area thereof there is dropped from the
top of the bottom part material and heat-sealed thereto an inner
floor 46 providing a central space 47 shaped from an upstanding
wall 48 upon the donut-shaped or gas-receiving space 49 being
inflated as best shown in FIG. 7. The shaping of this bottom part
41 to provide the space 47 is effected by adequate heat-sealing so
that the bottom part 41 will be caused to have its donut shape when
inflated.
The rigid seat 42 is heat-sealed or adhered on its bottom surface
with the top surface of the bottom part 41 as at 51 and has a
central opening 52, the periphery of which is flanged as shown at
53 to provide a top annular space for receiving the periphery of a
removable liner 54. This liner 54 is made of thin inexpensive
liquid-containing material and has a top flange 55 that contains
snap-fastening elements 56 that can cooperate with corresponding
snap-fastening elements 57 peripherally spaced along the flange 53
at the opening 52 at the seat part 42. Tabs 58 are provided on the
flange 55 of the liner adjacent to the male fastening elements 56
so that the liner can be easily pulled out of the seat opening 52
and off its flange 53.
The capsule-puncturing device 44 as best shown in FIG. 8, comprises
generally a bottom cup-shaped part 61, having a plug 62 in the
bottom thereof with an axial opening 63 with which hose 43
communicates and connected by its flange 64 to the bottom closed
end of the bottom part of 61. In the opening 63 there is fixed a
vertically extending puncturing pin 66 extending rigidly from a
perforated washer 67. The upper end of the central opening 63 is
sized as indicated at 68 to receive a reduced diameter and closure
69 of a charged capsule 71 and when pressure is applied downwardly
to this capsule the capsule will be punctured by the puncturing pin
66 so that its compressed gas will be discharged into the hose 43
that is connected by a valved inlet device 70 which is held by
flanges 73 and 74 in the wall of the bottom part 41 so that the
inflating gas is delivered to space 49.
The capsule 71 is inserted in the bottom part of 61 and inserted
thereto is a top part 76 that has an adjustable screw 77 inserted
into its upper end and to the bottom end of which is secured a seat
part conforming to the rounded end of the capsule to distribute
equal pressure thereover as the screw 77 is turned by a handle 76'
fixed by rivet 81 to the upper end of the screw 77. The capsule is
in this way punctured so that the compressed gas is readily
discharged from this device 44 into the annular chamber 49 of the
bottom part 41 to inflate the same from a deflated condition as
shown in FIG. 9 to an inflated condition as shown in FIGS. 6, 7 and
8.
The valve 70 is a one-way valve and is adapted so that it can be
turned to permit the discharge of the air from the donut-shaped
space 49 of the bottom part 41. FIGS. 10 and 11, the flanges 73 and
74 are shown to be a part of a fitting 72 that is clamped by the
flanges 73 and 74 to the wall of the inflatable bottom part 41.
This fitting 72 has a central opening 78 that is enlarged at its
outer ends and threaded to receive a nozzle fitting 79 that has a
central hole 80 for receiving the gas from the hose 43 that is
fixed thereover, and a spring ball valve 82, having a retaining
spring 83 and a retainer screw 84. The ball 82 with its spring 83
and screw 84 provided in an enlarged inserted opening as indicated
at 85, so that as pressure is applied to the ball 82 it will open
from its seat 86 to allow the gas to pass through a hole 87 in the
screw 84, the passage 78 and into the space 49.
The flanged fitting 72 has in the part of its axial opening 78
receiving the valved fitting 79, discharge grooves 88 with which a
transverse hole 89 can be aligned upon turning the valved fitting
79 by its knob 91 for alignment with these recesses 88. Thus when
it is desired to deflate the bottom part 41 and the space 49
therein, the knob 91 is turned to a position as shown in FIG. 11
for the gas to be exhausted from the opening 78 and the flanged
fitting 72. When it is desired to again inflate the bedpan, the
capsule-puncturing device is again loaded by removing the top 76
and placing another capsule 71 therein. Turning the screw 77 will
again discharge the capsule 71 and inflate the bedpan. Either
before inflating the bedpan or after, liner 54 can be inserted into
the space 47 and snap fasteners 56 in its periphery 55 joined with
the fastener openings in the flange 53 of the rigid seat part
42.
The deflated bedpan 40 can be inserted under the patient easily
since its height may not be more than 1 inch in dimension and the
patient can thereby be easily located on the same without strain to
the back, either by himself or by the hospital attendant. Once the
patient is upon the seat the capsule 71 can be punctured and
immediately the central space 47 is restored so that the liner
bottom can drop thereinto and thereby provide means for collecting
fecal matter or urine from the patient. Thereafter the bedpan can
be removed and with the liner taken therefrom it can be thrown away
with its content so that the bedpan can thereafter be used again
with little washing or cleaning. This same bedpan, of course, can
be used without the liner since the space 47 is provided, but will
be more difficult to clean than with the first form of the
invention wherein the seat is removable from the bottom part.
It will be understood that the inflation can be effected by a foot
pump, a hand pump, a compressed air source or a carbon-dioxide
cylinder as well as by the means that has been shown. When the
bottom part of the bedpan is inflated, the bedpan may have its
normal height of from 3 to 4 inches. The patient himself may,
through the capsule means shown in the second form of the
invention, handle the inflation of the bedpan by himself.
