First Claim
Patent Images
1. A faceplate for a two-piece ostomy appliance, said faceplate comprising a coupling ring for mechanically and detachably coupling said faceplate to a collection pouch and an adhesive wafer supporting said coupling ring for adhesively joining said faceplate to the peristomal skin surfaces of a patient;
- said wafer being generally planar and including a layer of hydrocolloid-containing adhesive skin barrier material;
wherein the improvement comprises said wafer having a recess facing in the direction of said coupling ring and having at least one side surface generally normal to the plane of said wafer;
said wafer also having a base surface extending along a plane below that of a surface of said wafer adjoining said recess;
said coupling ring including a portion thereof received in said recess and secured to the said base surface of said recess beneath the plane of said adjoining surface.

Abstract
An ostomy faceplate for a two-piece appliance is disclosed in which the coupling ring is partially recessed into the wafer of the faceplate. The wafer includes a hydrocolloid-containing adhesive layer that is provided with a recess that receives a portion of the coupling ring, thereby resulting in a faceplate of distinctively low profile and enhanced conformability.
