ABSTRACT:
A ring made of stiff, smooth material passes through concentric openings on a pair of separable plate members to accommodate the stoma to allow discharge into a disposable container attached to one of the plates. Annular washers around the plate openings and the ring seal against leakage, permit the plates to be quickly and easily separated and permit the appliance to be easily disassembled, if necessary, for cleaning.
