Abstract
Abstract A medical dressing comprising an embossed, thin polymeric film coated on one side with a medical grade, pressure-sensitive adhesive. The embossed film has a low coefficient of friction, preferably less than about 0.6, on the outer adhesive free surface which makes the film particularly resistant to unintentional removal by rubbing forces. The film is intended primarily for use as a blister dressing, but may also be provided with an absorbent pad for use as a wound dressing.

Claim 2
Dependent Claim
67 words
A thin film, self-adhesive dressing for the prevention and treatment of skin friction blisters comprising an embossed elastomeric film coated on one surface with a pressure-sensitive adhesive, said film having a thickness of from about 0.5 to 10 mils, a moisture vapor transmission rate of more then about 100 g/M 2 /day, and a coefficient of friction on the adhesive free surface of less than about 1.0.
Claim 3
Dependent Claim
32 words
The dressing of claim 1 wherein said film is embossed to provide at least one surface with a contact area of less than about 50% of the overall area of said film.
Claim 4
Dependent Claim
20 words
The dressing of claim 2 wherein the surface opposite said at least one surface is coated with a pressure-sensitive adhesive.
Claim 5
Dependent Claim
14 words
