Abstract
Abstract An orthopedic cast which is air permeable to permit ventilation to the surface of the skin, and which is non-wetting whereby the cast is quick to dry upon exposure to water. The cast includes a protective sleeve comprising a relatively open, air permeable, non-wetting fabric, and an overlying immobilizing structure which is also air permeable and non-wetting. The yarns of the sleeve fabric may be intimately admixed with a bacteriostatic agent to retard the growth of micro-organisms, and they may be texturized to provide extra body.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
100 words
An immobilizing orthopedic cast characterized by air permeability and non-wettability and thereby permitting air ventilation to the surface of the skin of a wearer and being quick to dry upon exposure to water, said cast comprising, an inner protective sleeve adapted to be positioned about a portion of the body of a wearer and comprising a relatively open, soft, resilient, air permeable fabric formed of interknit non-wetting, polymeric yarns, and an outer immobilizing structure surrounding said sleeve and comprising a plurality of superposed, rigid layers of a relatively open, air permeable non-wetting fabric adhered together and including interlaced glass yarns.
Claim 2
Dependent Claim
100 words
