Claim Text:
1. An adhesive composition for a skin-adhering medical device comprising a high molecular weight polymeric buffer composition which provides both pH buffering and fluid absorption, the composition comprising: about 55-75 wt. % high molecular weight PIB, about 2.5-18 wt. % liquid PIB, about 2-8 wt. % polymer fibers, about 8-15 wt. % cross linked high molecular weight polyacrylic acid, and about 4-10 wt. % cross-linked 75% neutralized high molecular polyacrylic acid, provided that if the fiber content is less than 3 wt. %, the amount of cross linked polyacrylic acid is at least about 9.5% and the amount of liquid PIB is at least about 5 wt. %.
