Abstract
Abstract A combination splint-compression dressing for an injured joint comprises a regenerated, cellulosic sponge formed to a predetermined shape to totally encapsulate the injured joint. The cellulosic sponge is hydrophilic and sufficiently open celled and porous so as to be highly absorbent through capillary action. An outer layer of a nonwoven resin impregnated web of organic fibers is bonded to the cellulosic sponge so as to provide temperature insulation and impart dimensional stability to the sponge. The sponge totally envelops the injured area and is used both for first aid and rehabilitation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
A combination splint-compression dressing for an injured ankle or foot comprising a preformed two layer sheet, the inner layer being a regenerated, open celled, swellable, cellulose sponge of about one-half inch and the outer layer being a nonwoven resin impregnated web of organic fibers of about one-quarter inch thick bonded to said inner layer, said dressing being formed with a foot section to foldably cover the foot area, an ankle section joined to the foot section through a tapered connecting section and a foldable section to cover the ankle area and overlap the foot area, said dressing being bendable in the area of the connecting section so as to permit the ankle section to bend at substantially right angles to the foot section.
Claim 2
Dependent Claim
