Abstract

Abstract Orthopedic supports are made from a flexible, resilient composite material which includes a base layer of a flexible, closed cell elastomeric material such as neoprene rubber in thin sheet form, with a multiplicity of relatively large air holes extending through the depth of the sheet and dispersed across the surface of the sheet. A skin-protecting first layer of a soft, flexible stretchable porous knitted fabric is adhered to a first face of the base layer. A protective second layer of a flexible, stretchable porous knitted fabric is adhered to the second face of the base layer. The composite material is porous to air and water passing through the depth of the composite layer. Orthopedic supports made from the material are sufficiently elastic to provide compression around a body part supported by the composite material in its stretched condition. The composite material is sufficiently porous to ventilate the supported body part during use such that elasticity and support is provided while heat discomfort and perspiration are prevented.
