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.
