Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
200 words
A sealing ring or pad specifically for the problems incident to sealing between a drainage pouch and the skin around the stoma opening in the abdomen of a patient in ostomy cases, comprising a permanently shaped open cell foam body having the properties of flexibility, elasticity, compressibility and non-solubility in water, said body having a stoma-receiving opening, a labyrinth of interconnecting cell cavities throughout the body providing relatively large surface areas in the body, said flexibility permitting the body to conform to the shape of the abdomen around the stoma area, said elasticity permitting said stoma opening in the body to be stretched and relaxed to create a snug fit against the stoma, and said compressibility permitting a tight seal effect between the body and the abdomen around the stoma area, a material having skin healing and protective properties incorporated in and filling said interconnecting cell cavities, said relatively large surface areas serving to effect adhesion of said material to the body and to substantially retain said material within the body, said structure providing more effective sealing action over a longer period of use in preventing passage of fecal stoma discharge through the sealing body and contacting the patient''s skin.
