Abstract
A method is disclosed for treating a wound or attaching a device or article to the skin using a film of pressure sensitive adhesive having dispersed therein a discontinuous gaseous phase contained within voids in the adhesive. The adhesive is formed from the polymerization of a hydrophilic premix and exhibits high moisture vapor transmission and fluid absorbency.
Claims23
A method of treating a wound comprising covering the wound with a dressing comprising a hydrophilic film of pressure sensitive adhesive, which film is continuous and liquid impermeable over its entire surface, said film having dispersed therein cellular voids containing a gaseous phase constituting at least 10 percent of the volume of said film, and a 0.76 mm thickness of said film having a moisture vapor transmission rate of at least about 400 g/m.sup.2 per 24 hours at 40.degree. C. and an 80 percent humidity differential.
A method of attaching a device or article to the skin comprising attaching said device or article to the skin with a pressure sensitive adhesive wherein said adhesive comprises a hydrophilic film which is continuous and liquid impermeable over its entire surface, said film having dispersed therein cellular voids containing a gaseous phase constituting at least 10 percent of the volume of said film, and a 0.76 mm thickness of said film having a moisture vapor transmission rate of at least about 400 g/m.sup.2 per 24 hours at 40.degree. C. and an 80 percent humidity differential.
