  • Patent number: 8303554
    Abstract: A body interface device for a urine aspiration system comprises a skin contact pad with gel adhesive for adhering to the skin, and a flexible cover attached to the pad. The pad includes at least one aperture for admitting urine through the pad into the body interface device. The flexible cover has a bulged form projecting away from the gasket. The flexible cover defines a urine receiving chamber facing towards the gasket, and recess facing away from the chamber for receiving at least a portion of a non-contact liquid sensor. The recess and chamber have a wall portion in common that separates the recess and the chamber. A liquid acquisition material in the chamber receives and transports urine for rapid sensing by the non-contact sensor. An aspiration unit is responsive to the non-contact liquid sensor to apply aspiration suction to the body interface device, upon detection of urine.

  • Patent number: 8142406
    Abstract: An ostomy coupling including a body-side coupling member, an appliance-side coupling member including plural fastener lugs, and a bracing member. The lugs flex independently of each other to provide plural independent latching fastenings. The bracing member is moved between a bracing position in which the bracing member locks the lugs by resisting flexing movement, and a non-bracing or dismounted position in which the lugs are free to flex. The ostomy coupling is used with an ostomy pouch or with a controlled evacuation device.

  • 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: 7947025
    Abstract: A drainable urine pouch includes a discharge portion that is foldable between a discharge position and a closed position. A security flap is sealed to both walls of the pouch by a through weld, to define a baffle near the discharge portion. The discharge portion includes a constriction, and a stepped profile with multiple step stages. The discharge portion has one or more bias members. A drainage adapter is releasably coupled to the discharge portion. The drainage adapter has a plug with a shoulder for abutting the constriction in the discharge portion, to locate the adapter correctly for obtaining a liquid-tight seal.

  • Patent number: 7857796
    Abstract: An ostomy appliance is described in the form of a controlled discharge device for controlling discharge from the stoma and/or an ostomy pouch for collecting discharged waste. The appliance may include one or more of: an elastomeric stoma seal for providing a seal around or directly against the stoma; a stoma occluder for occluding the stoma without passing internally into the stoma; a peristomal foam wall; a confinement seal for confining at least solid excreta to a confinement region adjacent to the stoma; a stowable collector bag; and interchangeable controlled discharge devices and ostomy pouches. The foam wall may provide a barrier to stool, but allow escape of flatus. The foam wall and/or the stoma occluder and/or the confinement seal may apply a force in a direction to increase the sealing force on the stoma seal.

  • Patent number: 7858836
    Abstract: An adhesive composition including an adhesive component and an enzyme inhibiting component for use in ostomy and wound care applications. The enzyme inhibitors are derived from tubers, such as potatoes. In ostomy, the adhesive composition helps to secure the collection bag or pouch to the skin. In wound care application, the adhesive composition secures the wound dressing to the skin. The adhesive composition also may be used to couple two or more ostomy or wound care components together.

  • Patent number: 7727188
    Abstract: The invention relates to a balloon catheter in which the balloon is mounted on the end of the catheter in a manner that creates a recess or pocket between the catheter wall and balloon wall. The recess or pocket opens toward the proximal end of the catheter. The rigid end of an introducer element or finger is received in the recess to attach it to the catheter. The distal end of the catheter, with the end of the introducer element in the recess, is inserted and positioned within the bowel by manipulating the introducer element or finger. After the catheter is properly positioned in the bowel, the introducer element or finger is withdrawn, detaching it from the catheter as the end of the introducer element slides out of the recess and then out of the bowel. The balloon is inflated prior to or after the withdrawal of the introducer element to anchor the end of the catheter in position within the bowel.

  • Patent number: 7722585
    Abstract: A drainable ostomy pouch has an outlet. Reinforcing members at the outlet are deformable by application of manual pressure at their ends to distend the outlet. The lateral edges of the reinforcing members may be offset, which encourages the reinforcing members to consistently bend away from each other. A peelable distributed mechanical engagement fastener secures the outlet in a folded condition. The fastener parts are hook-hook type plastic extrusions, and provide a snap-engagement. A security flap is foldable under the outlet when in its folded condition. The outlet is released in two stages.

  • Patent number: 7258661
    Abstract: An ostomy plug is described comprising first and second chambers having adjacent ends coupled to, and in fluid communication with, each other. The first chamber may be for insertion into a stoma. The second chamber may contain fluid for inflating the first chamber when the second chamber is squeezed or otherwise compressed. The plug may have a figure-of-eight configuration. The plug may be configured to permit venting of flatus while obstructing escape of other body waste from the stoma. The plug may incorporate an insertion aid for aiding insertion into a stoma. The plug may also incorporate a device for regulating the inflation pressure of the fluid to avoid undesirably high inflation pressures in the stoma.

  • Patent number: 7160275
    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.
