Reformable convex adapter for ostomy appliance
First Claim
1. A convex adapter for use with an adhesive faceplate of an ostomy appliance, comprising an adapter ring formed entirely of a soft shape-recoverable skin barrier material having a convex bodyside surface, a generally planar opposite surface, and a centrally-located stoma-receiving opening therethrough;
- a removable release sheet covering said opposite surface; and
a substantially non-stretchable and removable cover film covering said convex surface;
said barrier material consisting essentially of a continuous phase of an elastomeric adhesive and a discontinuous phase of moisture-absorbing and swellable hydrocolloid particles dispersed therein;
said removable cover film being sufficiently transparent for revealing said adapter ring therethrough and having a marginal portion extending outwardly beyond the periphery of said adapter ring.

Abstract
A convex adapter for ostomy appliances is disclosed, the adapter including an adapter ring formed entirely of a soft, tacky, moisture-absorbent and swellable, hydrocolloid-containing adhesive material, one that retains its integrity on hydration and is shape-recoverable when compressive forces are removed, and a thin substantially non-stretchable cover film extending over and beyond the convex bodyside surface of that ring. The film is removably attached to the ring and is preferably transparent (or translucent) so that at least the outline of the ring may be seen through it. A flexible but substantially non-stretchable release sheet is removably attached to the opposite pouchside surface of the ring and may be peeled away from the ring during an initial step in the use of the product.
