A dressing especially for covering wounds or preventing or treating blisters, comprising a water vapor pervious carrier film uniformly covered with an adhesive layer, wherein there is centrally disposed on the adhesive layer a water vapor pervious polyurethane matrix which is beveled from an especially central point to the edge of the adhesive layer, although the periphery of the adhesive layer is at least partially not covered by the polyurethane matrix.

Dressing

In a surgical composition comprising a liquid monomeric and powdered polymeric acrylate or methacrylate, a catalyst and an accelerator, the composition upon mixing of the liquid and powdered constituents passing through a plastic state to a solid state, the improvement which comprises including in the composition about 1 to 15% by weight of dimethyl sulfoxide. The product exhibits reduced cytotoxicity.

Surgical material

A water-soluble, pressure-sensitive, self-adhesive composition comprising a limited class of copolymers and a specific plasticizer which is completely neutralized with potassium hydroxide. The composition comprises 30 to 80 parts of a copolymer of 70 to 88% by weight acrylic acid butyl ester and 12 to 30% by weight vinyl carboxylic acid. The ester may be substituted in an amount of 3 to 12% by weight by acrylic acid-2-ethylhexyl ester and/or 5 to 25% by weight by a mixture of vinyl acetate and fumaric acid dialkyl ester. The composition also includes 20 to 70 parts by weight of a water soluble plasticizer which is ethoxylated phenol (or alkylphenol), ethoxylated alkyl mono- or diamine, or an ethoxylated alkyl ammonium compound. The composition is particularly useful for the production of adhesive tapes and similar articles useful in the papermaking industry for maintaining paper webs in continuous form.
