Abstract: The disclosure belongs to the field of aerospace technology, and in particular relates to a method of urination and defecation in space. The method may include: forming a sealed space between a spacesuit below the waist and above the two thighs and the human skin before an astronaut urinates or defecates, and using, by the astronauts, the sealed space to urinate or defecate. The disclosure can confine the excrements in a small sealed space, and the operation thereof is simple, convenient and fast, and no excessive cost is required, and no pollution is caused in the spacesuit and the cabin, facilitating the astronauts' work in space.

Abstract: Ostomy irrigation sleeve having a tubular shape and a first end with a first opening for receiving ostomy discharge material and a second, opposite end with a second opening for discharge of the ostomy discharge material into a discharge unit, for example a toilet, after guidance through the sleeve. The irrigation sleeve is made of a flexible, water soluble material configured to be water soluble only after a certain time of exposure to liquid, wherein the certain time is at least 3 minutes.

Abstract: A portable waste collection device comprises a first container and an adjacent second container. The first container has an interior volume adapted to receive and contain waste. The second container has an interior volume adapted to contain a flushing solution. The second container has a discharge port adapted to permit flushing solution contained in the second container to be discharged from the second container into the first container. The second container comprises a pump for pumping a desired amount of the flushing solution from the second container into the first container.

Abstract: A bedpan providing ease of use, comfort, and cleanability. The bedpan includes a body member defining a reservoir shaped and dimensioned for receiving bodily waste. The body member includes a closed base section adapted for retaining bodily wasted deposited within the bedpan and an open support section. The support section includes a central opening providing access to the reservoir defined by the body member. The central opening is defined by first and second inwardly inclined walls extending from a first end of the body member toward a second end of the body member. The support section further includes a forward support surface adjacent the first end of the body member. The forward support surface has a forward end adjacent the base member and a rearward end adjacent the first and second inwardly inclined walls, wherein the forward support surface is generally horizontal and tapers downwardly as it extends toward the base section.

Abstract: A urinal device for use by female persons not having the use of their legs while seated in a chair or wheelchair. The urinal device has a pie-slice shaped shallow pan with a swollen, bulbous cross-section lip completely around the periphery thereof and a perforated splash plate. A handle is affixed to the pan opposite the narrow end of the pan so that the impaired person may insert the pan beneath her body without lifting her body or legs from the chair seat. The pan is continuously drained during use by means of a drainage hose connected to a urine receiving container.

Abstract: A conventional bedpan having sidewalls topped by an outwardly curved seat contains, in the forward end, a cabinet with a wall opening into the bedpan and containing a large extendible tube which may be withdrawn to function as a urinal for male patients.

Abstract: A portable bedpan operated by pump comprising a body including a water box, a remnant box, two filth boxes, and a vacuum pump, a pan engagable with the body, a pushing cylinder located in the body for pushing the bedpan and the front end of cylinder being detachably connected with the bedpan, a plurality of hoses contractibly connected between the first filth box and the bedpan, the first filth box sucking filth of the bedpan, the second filth box being interconnected with the first filth box so as to receive overflowing filth from the first filth box, a remnant box for accumulating remnant filth of the pan bottom, and plurality of valves installed at each connecting hose for regulating the fluid flow in connection with the pumping operation.

Abstract: A urinal having a semi-rigid housing is useable by either a male or a female to receive urine discharged by a person whether in a seated or in a supine position. A cappable opening to the collector includes a spout configured to receivingly support a penis when used by a male and the combination of the spout and opening is configured to develop a seal extending from the vaginal opening to a point above the urethra to prevent urine seepage when used by a female. Opposed sides of the collector are concave to mate with the curvature of the user's thighs and help maintain the urinal in place during use. A specially configured handle at the upper rear end of the housing aids in manipulating the urinal into and out of position of use and in minimizing the danger of inadvertent tipping.
