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 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: A convex insert system for an ostomy appliance includes a convex insert and a mounting member on the inner wall of an annular coupling. When the convex insert is mounted on the mounting member, the appliance has a convex curvature which when properly positioned helps the patient's stomal to protrude.

Abstract: In the first embodiment, the faceplate coupling ring is of conventional design and includes an axially extending rib with a radially outwardly extending rim and a radially inwardly extending deflectable sealing strip. The pouch coupling ring includes inner and outer spaced walls, forming a channel for receiving the rib. First and second protrusions extend inwardly from points on the interior surface of the walls proximate the ends thereof. The first protrusion cooperates with the rim and the second protrusion cooperates with the tip of the sealing strip, to securely retain the rib within the channel. The walls of the channel have reduced thickness and are easily deflectable as the rib is inserted into the channel, such that coupling of the rings is facilitated but decoupling requires the conventional amount of force due to the second protrusion.
