Abstract: A plastic composition adapted for use in contact with the skin, especially in the form of a pad applied to the skin, is manufactured by reacting a mixture of acrylamide-beta methacryloxyethyltrimethylammonium methyl sulfate copolymer, up to about 10 parts of acrylamide-sodium acrylate copolymer per part of said acrylamide-beta methacryloxyethyltrimethylammonium methyl sulfate copolymer, said acrylamide-sodium acrylate copolymer containing up to about 4% of sodium acrylate, and ethylene glycol in an amount sufficient to form a semisolid gel, said proportions being by weight. Useful embodiments of the pad include a sealing pad for an ostomy appliance and a skin-covering pad incorporated in a bandage.

Abstract: A plastic composition prepared by the reaction of a non-ionic water soluble acrylic polyelectrolyte and a cationic water soluble acrylic polyelectrolyte with propylene glycol and incorporating or conducting the reaction in the presence of polyvinyl pyrrolidone with or without water. In one embodiment a plastic composition adapted for use in contact with the skin, especially in the form of a pad, seal or bandage is prepared by reacting a mixture of: (1) acrylamide-beta methacrylyloxyethyl trimethyl ammonium sulfate copolymer; (2) polyacrylamide; (3) propylene glycol; and (4) polyvinyl pyrrolidone. The plastic composition can contain glycerin in varying amounts to enhance the "feel" and flexibility of the final product. Water can be incorporated with the polyvinyl pyrrolidone to reduce the gel time and facilitate the molding process.

Abstract: A valve in the nature of a check-valve for use in the fluid lines of enema and stoma-irrigating units, and the like, for permitting flow of material therethrough in one direction but not in the reverse direction, and which may be quickly and easily dissassembled, cleaned and re-assembled.
