Abstract
Abstract Stomal devices having controlled release so that disposable stoma bags can be easily replaced without disturbing the peristomal covering attached to the skin. One such device comprises a peristomal covering including an adhesive member and backing member formed of polymeric material having a geometric pattern embossed therein. Another embodiment comprises attaching such embossed polymeric material directly to the adhesive face plate of a disposable stoma bag. Another embodiment comprises forming the stoma bag from the flexible embossed polymeric material which can serve as the backing member.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
53 words
A peristomal covering comprising an adhesive member attached to a polymeric backing member having an embossed geometric pattern wherein the exposed surface of said backing member has continuous raised uncoated ridges separating the geometric dimples said raised surface is adapted to be contacted by the adhesive face plate of a disposable stoma bag.
Claim 2
Dependent Claim
53 words
