Convex insert for ostomy device
First Claim
1. An insert for a faceplate of a two piece ostomy device, the faceplate having a surface and comprising a coupling ring affixed to the surface of the faceplate and having axially extending rib means with substantially rigid sealing flange means partially defined by a substantially radially inwardly extending surface, said flange means having a given inner circumference, said insert comprising a substantially annular body, said body comprising a non-deformable convex portion and a deformable portion, said deformable portion having an outer edge with a circumference normally slightly larger than said flange means inner circumference, said outer edge of said deformable portion being adapted to be temporarily reduced in size as said insert passes through said coupling ring to a position where said body is situated between the coupling ring and the faceplate surface and thereafter to return toward its original size such that said outer edge lodges under said flange means surface.

Abstract
The insert is received within the coupling ring of the faceplate of a two piece ostomy device. The coupling ring has an axially extending rib and a rigid sealing flange defined in part by a radially inwardly extending surface. The insert includes a convex annular body with an arcuate relatively non-deformable portion and a deformable circumferential portion. The deformable portion has an outer edge with a circumference which is normally slightly larger than the inner circumference of the sealing flange. The circumference of the deformable portion is temporarily reduced as the insert passes through the ring. Once the insert is situated under the flange surface, the circumference returns to its normal dimension and the insert is securely seated.

- 11. In combination, a faceplate of a two piece ostomy device said faceplate having a surface comprising a coupling ring affixed to the surface of the faceplate and having axially extending rib means and rigid sealing flange means partially defined by a substantially radially inwardly extending surface, said flange means having a given inner circumference, and an insert comprising a substantially annular body, said body comprising a non-deformable convex portion and a deformable portion, said deformable portion having an outer edge with a circumference normally slightly larger than said flange means inner circumference, said circumference of said outer edge being adapted to be temporarily reduced to in size permit said insert to pass through said flange means of said coupling ring to a position where said body is between the coupling and the faceplate surface and thereafter return towards its original size such that said outer edge lodges under said flange means surface.
