Abstract
Abstract An appliance and sealing system for application to patients who have had surgery for colostomy, ileostomy or the like, for sealing a pouch or bag to the patient''s skin around the stoma so the pouch is in position to receive discharge from the stoma. The sealing system is a mass or ring of water insoluble pressure sensitive gel-like material which adheres to both the pouch and the patient''s skin. The adhesive can contain some water soluble ingredients if desired. The pressure sensitive adhesive may be made by preparing a melt mix of mineral oil, an aromatic-aliphatic polymer such as a copolymer styrene and isobutylene and a vinyl polymer such as an ethylene-vinyl acetate copolymer. The melt mix is poured into suitable molds and permitted to gel to form the seal. Both the external surface and the internal mass of the seal have properties of pressure sensitive tack, elasticity, flexibility, compressibility and kneadability. The adhesive mass can be marketed in combination with the pouch or as an individual item in the form of a ring-shaped seal having release liner on both surfaces.
