Abstract
Abstract A surgical dressing in the form of a plastic, foraminated bandage which may be wound about a diseased, deformed or broken part to produce a helix thereabout, and thereafter rendered rigid or semirigid to produce a cast immobilizing the part. The bandage is constituted by a strip of thermoplastic material which is moldable, when heated, to permit the strip to be wound about the part, the strip being rendered semirigid or rigid when cooled to room temperature.

Claim 1
Independent Claim
147 words
A surgical bandage capable of being wound about a part to be immobilized to form a rigid cast, said bandage being constituted by a strip of thermoplastic material formed of an unvulcanized neoprene material which is rendered soft and pliable when heated to a temperature in the order of about 140* F., and which when thereafter exposed to room temperature is rendered rigid in a matter of minutes, said neoprene material incorporating red oxide of iron in a sufficient amount to impart a fleshlike hue thereto, said strip having a row of perforation extending longitudinally along the center thereof and an adhesive coating on the margins on either side of the row of perforations, whereby when the strip is wound about the part to be immobilized to form a helix whose convolutions are marginally overlapped and adhered to each other, the helix is ventilated by said perforations.
