Orthopedic system for immobilizing and supporting body parts

摘要

A unitized cast system for immobilizing and supporting a body part. The unitized casting system includes a first inner layer for padding and dissipating heat against the patient's skin. A second layer is formed from a thermoformable structural material such as perforated plastic. A protective third outer layer is provided to provide insulation for the second layer. These three layers are formed together to form a unitized cast system that is easily formed and applied to the patient.

1. A cast system for supporting a body part, said cast system comprising:
an inner layer for providing insulation and cushioning against the body part, said inner layer formed of flexible foam and having a first density; a middle layer malleable for a dwell time when heated to conform about a body part and that provides rigid support for the body part when said middle layer is at room temperature, said middle layer having a second density; an outer layer for providing insulation for said middle layer, said outer layer formed of flexible foam and having a third density; and said inner layer, said middle layer, and said outer layer are assembled together to form a unitized cast, with an edge of said middle layer recessed from corresponding edges of said inner layer and said outer layer, and with said edges of said inner layer and said outer layer sealed together encapsulating said middle layer, wherein said first and third densities being less than the second density of the middle layer increases the dwell time of said middle layer, and wherein the encapsulation of the middle layer by the inner layer and the outer layer increases the dwell time of the middle layer.
