Abstract: An ostomy coupling is described of the type comprising a locking member in the form of a resilient split ring, for fastening two ostomy coupling members together. One feature of the invention is that one of the coupling members comprises a tapered seal seat surface for cooperating with a deflectable seal wing carried by the other member. The tapered seal seat has a smoothly curved taper, to enable a relatively large seal area to be provided within a low coupling profile height. Another feature of one form of the invention is that the split ring has an inclined outer surface to form a smooth profile with the coupling member on which it is carried. Another feature of another form of the invention is that each limb of the split ring is bifurcated to receive a radially projecting guide of the coupling member, on which the split ring is mounted.

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.

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: An ostomy pouch clamp/closure and a method of production are described. The clamp comprises a blade member and a trough member hingedly coupled to the blade member and having a blade member receiving channel. At least one of the members comprises integrally molded first and second portions, being respectively a rigid portion of a first relatively hard plastics, and a soft or comfortable-feel portion of a second relatively deformable plastics. The clamp can be formed using two-shot molding. The channel also includes an elongate constriction for releasably retaining the blade member in the channel, providing a mechanical interlock along the entire length of the clamp. The clamp also includes a snap lock at its distal end.

Abstract: A balloon-like member is received in the bowel and inflated to seal the stoma. The member includes a thin, flexible wall defining an opening. A rigid or semi-rigid cap retains the member and closes the opening in the member wall. Skin comfortable adhesive adheres the edge of the cap to the tissue surrounding the stoma. A flexible dilation tube facilitates insertion of the member and cooperates with a pump to inflate the member. The cap is preferably removeably attached to a standard two-piece ostomy faceplate and is provided with a filter element to vent flatus.

Abstract: A pouch includes a front wall (22), a rear wall (24) having an entrance aperture (32), and a central partition (36). The partition divides the pouch into an entrance chamber (38) and a collection chamber (40) located one in front of the other. A pad (42) of superabsorbent material is located in the collection chamber (40) and extends above the lower level of the entrance aperture (32). In use, urine entering the pouch is directed downwardly and through a lower permeable region (36) of the partition, whereafter it is absorbed and gelled by the superabsorbent material pad. The urine is also wicked upwardly by the pad (42) so that the full height of the pouch can be used as a liquid-collection region.

Abstract: An ostomy pouch (10) is described having an automatic pressure relief valve (82) which opens and closes automatically in response to the differential gas pressure across the valve to vent flatus. In one form, the valve comprises a diaphragm which seals against a seat by the use of a tacky gel or oil. The diaphragm is pinched towards one side and flexes as a flap. In one preferred form, the valve (84) is used in combination with a deodorizing filter (82). The filter may be mounted co-axially with the valve, or it may be mounted separately and offset from the valve. A sub-envelope assembly (80) is described carrying the valve (84) and the filter (82) and defining a buffer volume between the valve and filter to compensate for the different flow characteristics of the valve and filter.

Abstract: An ostomy pouch (10) is defined by a front wall (12) and a rear wall (14) having a stoma aperture (18). One or more rupturable capsules (24) are carried on a carrier or intervening wall (44) welded to the front and rear walls at a common weld seam (16). When desired, a capsule (24) can be ruptured by squeezing, the pouch wall together at that position, to dispense the contents (for example, a deodorising agent, a disinfectant or a preservative). In one form, the carrier does not cover the stoma aperture. In another form, the contents are dispensed on the side facing the front wall (12), and the curtain (44) shields the stoma aperture (18), to prevent the agent spurting out or contacting the stoma. In another form, one or more rupturable capsules may be arranged on the front wall (12) or on the rear wall (14). A plurality of the capsules (24) may contain different agents if desired.

Abstract: A flush fit ostomy coupling (110) includes a bagside coupling member (114) with a front flange (116) from which an outer wall (22) depends rearwardly. A channel is formed between the outer wall and an inner wall (124) supported by the outer wall. The bodyside coupling member (112) carries sealing means in form of first and second substantially radially projecting sealing fins (152). The sealing fins are able to deflect to form a cylindrical band seal against one wall (122) of the channel. The opposite wall (124) of the channel forms an interlock with the bodyside coupling member. The radial sealing fin may be used with other types of ostomy coupling. Also, the flush fit design may employ other types of seal.
