    Abstract: A method of making a gas-permeable liquid-impermeable membrane includes the steps of perforating a film of linear low density polyethylene (or other suitable polyolefin) in such a way as to yield an array of holes each having an average diameter of approximately 350, microns and then solution coating the needled film with a porous polyurethane material having pores of a pore size of 1 to 10 microns.Such a film is advantageously embodied in an ileostomy bag, and is fixed to a bag wall thereof in a location to prevent faecal material contacting the bag filter, by a heat or RF welding operation by which the polyolefin is welded to the bag wall which carries the filter. In use, the polyurethane is exposed to the bag contents, and permits gases to pass but prevents any liquid reaching the filter.

    Abstract: An ostomy pouch (10) includes a front wall (12) provided with a comfort layer (16) and a vent (22). An apertured cover layer (24) is secured to the front wall (12) through the comfort layer (16) to define a chamber for a filter element (28) and to provide a smooth surface to which can be applied an adhesive sticker. The cover layer (24) includes a plurality of apertures (30), and the flow rate through the vent can be controlled by positioning the sticker to selectively block one or more of the apertures (30). An adhesive wafer (40) includes both circular and non-circular (race-track) cut out guidelines for enabling the aperture to be cut to any desired shape and size. The wafer (40) is secured to the pouch along a weld line having a shape corresponding to a combined circular and race-track silhouette.

    Abstract: A distinctive absorbent article includes a backsheet layer and an absorbent body superposed in adjacent, facing relation with the backsheet layer. An actuating member connects to the article in liquid communication with the absorbent body and is composed of a liquid-contractible material. The liquid-contractible material is capable of shrinking upon contact with an aqueous liquid while maintaining a substantially unitary configuration. An indicating mechanism is connected to the actuating member for designating a wetness condition of the absorbent body, and is translatable along a selected path in response to the shrinkage of the actuating member.

    Abstract: A resilient, substantially flat, non-adherent flexible wound dressing which remains flexible when dry, of hydrophobic material capable of retaining substantial quantities of fluid wound exudate. One or both major surfaces may be non-adherent woundcontacting surfaces which may include fenestrated film or interrupted exposed portions of flattened sheetlike fused fibers having a filmlike appearance, or both. The interior of hydrophobic fibers is arranged to retain fluid wound exudate by capillary action. If superimposed fenestrated film is used, it may be united to the hydrophobic fibers either at or inside the dressing edges, or both, preferably by melt sealing. Dressings may be prepared by pressing (with substantially no relative movement) the hydrophobic fibrous material, preferably a carded or air laid batt together with any fenestrated film between closely adjacent parallel uni-directionally moving surfaces of a foam and a stainless steel belt which is heated and then cooled. In the absence of a covering fenestrated film, the surface fibers of the batt, pressed against the heated belt, are softened, flattened, fused and subsequently congealed in contact with the polished belt, thereby forming sheetlike interrupted surface areas of filmlike appearance. When a fenestrated film is added to the dressing, it passes in contact with the stainless belt and may be melt sealed in passage to the fibrous batt with sheetlike interrupted areas of fused fibers being formed, or not formed depending upon the temperature the fibers reach, through the holes in the fenestrated film. A melt edge version of the dressing with soft edges may be made with a cooled perimeter clamp adjacent which a hot perimeter knife cuts and seals the dressing edge.
