Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
A collapsible bedpan comprising an inflatable, disposable bottom part, generally of donut shape, having a central bottom closed opening, a rigid seat conforming generally to the shape of the bottom part and adapted to overlie the periphery of the same and having a central opening aligned with the central opening in the bottom part to receive fecal matter and urine from a patient seated upon the seat, said bedpan upon being collapsed being of the order of 1 inch in thickness and when inflated being from 3 to 4 inches in height the same as a standard metal bedpan, valved means connected to the inflatable bottom part through which gas under pressure can be passed to inflate the bottom part.
Claim 2
Dependent Claim
120 words
A collapsible bedpan comprising an inflatable, disposable bottom part, generally of donut shape, having a central bottom closed opening, a rigid seat conforming generally to the shape of the bottom part and adapted to overlie the periphery of the same and having a central opening aligned with the central opening in the bottom part to receive fecal matter and urine from a patient seated upon the seat, said bedpan upon being collapsed being of the order of 1 inch in thickness and when inflated being from 3 to 4 inches in height the same as a standard metal bedpan, valved means connected to the inflatable bottom part through which gas under pressure can be passed to inflate the bottom part.
Claim 3
Dependent Claim
23 words
A collapsible bedpan, as defined in claim 1, and said rigid seat being detachably secured to the upper surface of the bottom part.
Claim 4
Dependent Claim
73 words
A collapsible bedpan, as defined in claim 1, and said seat being fixedly attached to the top surface of the bottom part, said seat opening having fastening elements about the periphery thereof, and a liner adapted to fill the space within the bottom part and to be attached by cooperating fastening elements on the periphery thereof to the fastening elements of the seat, said liner thereby being detachably removable from the inflatable bedpan.
Claim 5
Dependent Claim
126 words
A collapsible bedpan, as defined in claim 1, and a capsule-puncturing device adapted to receive a charged capsule and having means for effecting the puncturing of capsule when located therein to discharge inflating gas, a hose extending from the puncturing device to the inflatable bottom part, and means connecting the hose to the inflating bottom part including a one-way valve fitting, a flange fitting connected to the wall of the bottom part and said valve fitting turnable in said flange fitting, said flange fitting having exhaust recesses cooperable with the one-way ball valve fitting to discharge the gas from the bottom part without removal of the ball valve fitting therefrom and adapted to be further turned to close off the exhaust passages of the flanged fitting.
Claim 6
Dependent Claim
68 words
A collapsible bedpan, as defined in claim 2, and said bottom part having snap fastener tabs peripherally spaced around the outer periphery thereof with fastener elements thereon, and said seat having cooperating fastening elements spaced about the underside of the outer periphery of said seat and adapted to cooperate with the fastener tabs of the bottom part, whereby to releaseably secure the rigid seat to the bottom part.
Claim 7
Dependent Claim
72 words
A collapsible bedpan, as defined in claim 3, and said seat having an inwardly extending flange about its opening, said liner having a peripheral flange with the snap fastener elements thereon, and cooperating snAp fastener elements provided upon the inwardly extending flange in the opening of the seat part, tabs extending from the periphery of the liner element to facilitate the removal of the liner from the opening of the seat part.
Claim 8
Dependent Claim
66 words
A collapsible bedpan, as defined in claim 1, and said inflatable bottom part comprising a bottom member providing the full bottom surface of the bedpan, a top member secured to the bottom member inwardly of the outer periphery thereof to provide the inflatable donut-shaped space thereover and having an outer peripheral flange and the outer flanges of the top and bottom member being sealed together thereabout.
Claim 9
Dependent Claim
78 words
A collapsible bedpan, as defined in claim 7, and snap fastener straps connected to the inflatable bottom part and extending upwardly over the flanged periphery of the bottom part and having snap fastener elements thereon, said seat part having snap fastener elements on the bottom and about the periphery thereof and receiving respectively the snap fastener elements of the straps connected to the bottom part whereby the seat part is made detachably connected to the inflatable bottom part.
Claim 10
Dependent Claim
64 words
A collapsible bedpan, as defined in claim 1, and said bottom part being formed of an inflatable member having a bottom portion and a top portion, and said top portion being drawn into the member and a bottom wall of the recess being spread over the bottom portion to provide a double thickness bottom space within the central space of the inflatable bottom part.
Claim 11
Dependent Claim
27 words
A collapsible bedpan, as defined in claim 1, said seat being reusable, and said inflatable bottom part being made of vinyllike material, may be reusable and disposable.
