Sealing material for ostomy devices
First Claim
1. In an ostomy system for covering intestinal and similar stomas in a human body, comprising an ostomy device surrounding or covering said stoma and attached to the human body by sealing means, the improvement which comprises utilizing as a sealing means a shaped, gel-like composition comprising at least one physically cross-linked elastomer selected from the group consisting of styrene-olefin-styrene block copolymers and ethylene-propylene block copolymers, forming a continuous phase and at least one hydrocolloid dispersed therein, said hydrocolloid being selected from the group consisting of guar gum, pectin, sodium carboxymethyl cellulose, sodium polyacrylate, and mixtures thereof, said compositions also containing a hydrocarbon tackifier selected from the group consisting of polymers and copolymers of dicylopentadiene, alpha-pinene or beta-pinene, and wherein said gel-like composition has a low resistance to quick deformation and a rapid recovery to its original shape after deformation, whereby the seal between the ostomy device and epidermis of the human body as well as the seal between the stoma and the portion of epidermis exposable to discharge from the stoma are maintained intact, even under rapid body movement.

Abstract
The invention relates to a sealing material for use in connection with ostomy devices, particularly stoma pouches, to surround and protect a stoma in the human body. The improvement is that the material is a shaped, gel-like composition composed of a largely continuous phase consisting of a physically cross-linked elastomer or a mixture of such elastomers, and preferably, but optionally, one or more hydrocarbon tackifier resins and likewise optionally, but preferably, an oil extender; and distributed in the continuous phase one or more hydrocolloids. The gel-like composition has a low resistance to quick deformation and a rapid recovery to the original shape after deformation.
