  • Patent number: 10166147
    Abstract: An absorbent article that includes an outer covering made of two liquid-permeable cover layers that are joined together to form a pocket, and an inner layer that is initially freely movable within the pocket. The inner layer includes a mixture of particles of a superabsorbent polymer and substances that are osmotically comparatively weaker than the particles. When the absorbent article is applied to a human or animal skin surface to cover a wound, the absorbent article exerts an osmotic pressure via which endogenous wound exudate is removed from the wound. Thus, the absorbent article assists, both in a surface region and in a tissue depth, a normal interstitial hydration of the tissue by directing the wound fluids in a direction of flow to the skin surface and into the absorbent article, and by keeping the wound fluids that flow to the skin surface in the absorbent article.

  • Patent number: 8096980
    Abstract: A flexible membrane is situated within a rigid or semi-rigid cap. The edge of the cap wall is adhesively fixed to the tissue surrounding the stoma. The interior of the cap is pressurized to press the membrane to seal the stoma against the discharge of solid and semi-solid waste. Gas escapes through a vent with a filter element. The cap can be pressurized by an external pump or an integral pump member situated on top of the cap. A relief valve prevents over pressurization. A collection pouch can be provided as part of a device. The device can be removably mounted on a standard two-piece faceplate.

  • Patent number: 8070737
    Abstract: A controlled evacuation ostomy appliance comprises a membrane that is urged into sealing engagement with a stoma, by the generation of radial tension in the membrane. A tensioning device applies tension, with respect to the stoma, at one or more positions that are (i) outboard of the periphery of the projecting portion of the stoma, and/or (ii) between the level of the peristomal skin and the level of the most projecting part of the stoma. Tension limiting means are disclosed. The membrane may be gas-permeable to allow flatus to be vented.

  • Patent number: 8007483
    Abstract: An ostomy bag with a filter assembly having a gas filter and a pre-filter for preventing or delaying solid/semisolid matter and liquid from reaching the gas filter. The pre-filter is at least substantially flat and comprises a number of constrictions, such as ribs extending along and between two inner surface parts of the channel. These constrictions/ribs form narrower and wider passages where the gas may more quickly pass a narrow passage and where the wider passages tend to receive and hold the liquid, solid matter and semisolid matter. At least a part of one of the surfaces may comprise an interactive agent adapted to interact with the fluid passing through the gas channel.

    Abstract: A high performance flatus gas filter assembly, and a body waste collection pouch with which it may be used, along with a method for making such an assembly, are disclosed. The assembly includes a filter pad having first and second layers of deodorizing filter media with an imperforate gas and odor barrier layer sandwiched therebetween for blocking the direct flow of gases between the opposing inner faces of the filter layers. An envelope of liquid and gas impermeable material defines a chamber for enclosing the pad. The envelope has walls with first and second openings communicating with central portions of the first and second filter layers, and defines a peripheral space about the pad to permit the outward flow of flatus gases from the peripheral edge surface of one of the filter layers inwardly into the peripheral edge surface of the other of the filter layers.
