Abstract
A casting article and method for forming an orthopedic cast around an animal body part. The article comprises a unitary blank having first and second lateral free edges. The blank is dimensioned and the free edges are shaped to extend the length of the body part and to at least circumferentially envelop the body part. The blank includes a pliant, extensible layer of a foam member, an extensible fabric bonded to the foam member and a curable resin which, upon activation of the resin and closure of the lateral free edges of the blank around the body part, results in the orthopedic cast.
Claims35
An article suitable for forming an orthopedic cast around an animal body part comprising:
- a unitary blank having first and second lateral free edges, said blank being dimensioned in one direction sufficient to extend the length of said body part and dimensioned in a second direction sufficient to at least circumferentially envelop said body part, said blank comprising:
- (a) a pliant, extensible layer of an at least partially open-celled foam member,
- (b) an extensible fabric bonded to at least one major surface of said foam member, and
- (c) a curable resin impregnatably associated with said foam member of said blank whereby, upon activating said curable resin and stretchingly bringing laterally disposed portions of said blank together into sealing relationship around said body part, said orthopedic cast is provided.
An article suitable for forming an orthopedic cast around an animal body part comprising:
- a unitary blank having first and second lateral free edges, said blank being dimensioned in one direction sufficient to extend the length of said body part and dimensioned in a second direction sufficient to circumferentially extend around to envelop said body part and to provide an overlap region, said blank comprising:
- (a) a pliant, extensible layer of a foam member,
- (b) an extensible fabric bonded to at least one major surface of said foam member, and
- (c) a curable resin impregnatably associated with said blank whereby, upon activating said curable resin and stretchingly bringing laterally disposed portions of said blank together into sealing relationship around said body part, said orthopedic cast is provided, and
- wherein at least one of said first and second lateral free edges of said blank has a curvilinear shape defining projection means, said projection means being positioned and dimensioned to be formed around portions of said body part whereby said sealing relationship is substantially smooth and pucker free.
