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. In the second embodiment, the deflectable sealing strip on the faceplate coupling ring is replaced by a rigid flange which cooperates with the second protrusion to substantially increase the decoupling force.

Occlusive attaching means comprising a first relatively thick adhesive component to be secured to the skin around the stoma and a relatively thin flexible second adhesive component to be secured to the skin at a distance from the stoma. Both adhesive components include an occlusive adhesive layer formulated as a blend containing one or more water soluble or swellable hydrocolloids dispersed in polyisobutylene along with other optional ingredients. The attaching means can be utilized as part of a one or two-piece ostomy system.

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.

Clamping systems for two piece ostomy device

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.

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.

The bayonet coupling uses a body side flange and a bag side flange. The body side flange has L-shaped openings engaged to engage with pins on the body side flange. The body side flange includes an annular detent which includes an O-ring for sealing purposes.

Bayonet coupling for ostomy device

The container has an elongated port section formed of a flexible cylindrical wall. A first tube member is lodged within the wall at a location spaced from the end thereof. A second tube member is forceably inserted within the first tube member, engaging a section of the wall therebetween. The engaged wall section may include a double wall thickness. One of the tube members is composed of substantially non-elastic material and the other is composed of relatively elastic material. The elastic member will deform so as to tightly seal the wall section. A detent may be present on one of the tube members to cooperate with a detent receiving recess on the other to enhance the strength of the seal. Any conventional drain valve or tubing can be connected to the protruding end of the second tube member.
