Abstract

Structure for and method of therapeutic treatment of a body portion to relieve swelling and pain and facilitate healing of injuries, wounds and incisions. The structure includes a shield adapted to be placed in intimate surface to surface contact with the body portion, a regulator for passing a fluid through the shield at a regulated temperature and/or flow rate, a control for controlling the flow and temperature of the fluid and a temperature sensor for modifying the temperature and flow of the fluid in response to monitored temperature which may be the temperature of the body portion. The shield is constructed of an inner and outer elastomric member, at least the inner member of which is in the mirror image form of the body portion to be treated, which inner and outer members are sealed together to form a pocket, fluid passing structure, which may be manifolded tubing in the form of the body portion within the pocket, and a gelatinuous substance within the pocket positioned between the fluid passing structure and the inner member. The inner and outer members may be directly molded on castings of the body portion and the tube structure may be adhered to the inner surface of the outer member. An air pocket and an air valve may be formed in the outer member. In use, the shield is positioned over a body portion to be treated in intimate surface to surface contact therewith, and fluid is passed through the tube from the regulator at a flow rate and having a temperature controlled by the controller modified by the monitored temperature to provide cryogenic therapy. Air under pressure may be placed in the air pocket to provide compression therapy.
