Claims
- 1. A convex insert system for an ostomy coupling comprising:a first circular ostomy coupling having an opening, said coupling including an inner annular surface around said opening for fitting around a user's stoma, said inner annular surface having an inwardly radially projecting rib extending at least partly circumferentially therearound, said inner annular surface including an axially extending portion having a distal top surface; and a convex insert having a resiliently deformable body with a circumferential edge and outer convex surface, said body including a slot portion proximate to said circumferential edge, said convex insert being instable when deformed within said inner annular surface so said rib is captured said slot portion and said convex insert is secured within said inner annular surface entirely below said distal top surface, said convex surface axially projecting from said coupling for directly contacting the user's body.
- 2. The convex insert system of claim 1 wherein said convex insert firer includes at least one tab projecting from said body, said slot portion being between said tab and said circumferential edge.
- 3. The convex insert system of claim 1 wherein at least one tab includes a plurality of tabs spaced circumferentially and proximate to said circumferential edge.
- 4. The convex insert system of claim 1 wherein said convex insert has a central opening for fitting around said stoma.
- 5. The convex insert system of claim 1 wherein said convex insert is substantially undeformed when rib is captured in said slot portion.
- 6. The convex insert system of claim 1 further comprising a second coupling securable to said first coupling without contacting said convex insert.
- 7. The convex insert system at claim 1 wherein said first coupling is secured to one surface faceplate, one surface of said faceplate having an adhesive for securement to a patient's skin.
- 8. The convex insert system of claim 1 further comprising a planar faceplate having two opposite surfaces, said first coupling being mounted on one of said opposite surfaces, a medical adhesive being mounted on said other of said opposite surfaces for attachment to a patient's body, said first coupling having an annular channel adapted to capture an annular sealing strip therein, said second coupling having an annular sealing strip adapted to be captured in said channel.
- 9. The convex insert system of claim 8 wherein said convex insert system further includes a releasable locking ring mounted on said first coupling, said locking ring locking said first coupling to said second coupling in a first position, and releasing said first coupling from said second coupling in a second position.
