Reformable convex adapter for ostomy appliance and method of use
First Claim
1. A convex adapter for use with an adhesive faceplate of an ostomy appliance, comprising an adapter ring formed entirely of soft shape-recoverable skin barrier material having a convex body surface, a generally planar opposing surface, and a centrally-located stoma-receiving opening therethrough;
- a removable release sheet covering said opposing surface; and
a 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, including an adapter ring formed entirely of soft, moisture-absorbent, hydrocolloid-containing adhesive material that retains its integrity on hydration and is shape-recoverable, and a thin stretchable cover film (preferably transparent or translucent) removably covering and extending over and beyond the ring'"'"'s convex bodyside surface. 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. With the release sheet so removed, a user may grasp adapter ring and its cover film and reform the ring so that its opening is sized and shaped to match a patient'"'"'s stoma, after which the reformed adapter ring is adhered to the adhesive faceplate of an ostomy appliance, the cover film is removed, and the combination faceplate/adapter is adhesively secured to a patient'"'"'s peristomal skin surfaces.

10. A method for providing an adhesive faceplate of an ostomy appliance with a convex adapter having an opening reformable to match the shape of a patient'"'"'s stoma, comprising the steps of providing an adapter ring composed of soft, shape-recoverable adhesive skin barrier material having a convex surface covered by a stretchable and removable cover film;
- said cover film being generally transparent and having an outer portion extending substantially beyond the periphery of said adapter ring;
gripping portions of said cover film and adapter ring and urging the same in different directions with sufficient force to alter the shape of said opening of said adapter ring so that it matches the outline of a patient'"'"'s stoma;
securing said adapter ring to the bodyside surface of an adhesive faceplate of an ostomy appliance while the opening of said ring is so altered in shape; and
then removing said cover film from said adapter ring and said faceplate. - View Dependent Claims (11, 12)
- said cover film being generally transparent and having an outer portion extending substantially beyond the periphery of said adapter ring;
