Abstract: To minimize trauma after surgery, a clamp is employed to sealingly engage specially configured coupling rings mounted on the adhesive faceplate and the collection pouch, respectively. Each of the coupling rings includes a radially extending annular projection. The circular clamp is designed to surround the coupling rings and receive the projections within an annular recess. The projections and recess have oppositely oriented camming surfaces which cooperates to draw the coupling rings toward each other as the clamp is tightened. The clamp is locked by a toggle clasp connected by a living hinge, a pin and socket arrangement, a serrated clasp or a change purse type clasp. An adaptor can be employed so that the clamp can be used with a pouch with a conventionally configured coupling ring.

Abstract: For use with one piece and two piece ostomy devices, the adapter is situated on the adhesive-coated body side of the dressing which attaches to the skin surrounding the stoma to mount the collection pouch. The adapter includes a substantially rigid, annular member with a convex surface and an annular adhesive wafer. The wafer overlaps the edge of the member exposing a portion of the adhesive surface. The wafer and member are protected by a plastic shield. The wafer and member are applied to the body side of the dressing, with the convex surface of the member adjacent the wafer, as they are removed from the plastic shield. The exposed adhesive surface of the wafer directly contacts the adhesive of the body side of the dressing to form a secure bond. The result is a dressing with a convex shaped body side having a substantially uninterrupted layer of adhesive.

Abstract: A member in the form of an overfilm or molded housing affixed to the pouch wall has a plurality of isolated vent passages. A separate filter assembly is situated in each of the passages. Adhesive coated covers are situated to obstruct the flow through all but a selected one of the passages. After the filter in the unobstructed passage has lost its effectiveness, the cover is removed from another passage and placed over the passage containing the used filter to obstruct same. The filter in each passage is used, in turn, by appropriate movement of the cover, until all of the filters have been used.
