  • Patent number: 5224223
    Abstract: The invention includes in part of a disposable. inflatable receptacle formed from a thermoplastic material, which when inflated can withstand compressive pressures, for body wastes of persons who are unable to use conventional bathroom facilities because they are confined to a bed due to illness or injury. The receptacle is larger than the conventional metal receptacle to provide more stability for a patient because of his bed confinement. The receptacle also provides improved positioning for the patient on the receptacle by the presence on at least two opposing sides of a rim surrounding the seating area. The receptacle has an upstanding portion on the front part of the seat which acts as a urinary shield. In a second form, the receptacle has a wedge-shaped rearward extension to support the back of a patient who cannot sit upon the receptacle but must use it from the prone position. The remaining part of the invention is a super absorbent pad inserted into the interior of the receptacle.
