2101272 9213506 PCTABS00014 A thermal compress cuff for treating an injured knee has a fluid impervious chamber of flexible material with an upper transverse portion and depending arms extending from the transverse portion. The transverse portion is adapted to encompass a portion of the limb above the knee and the depending arms are adapted to encompass the limb along the sides of the knee and a portion of the limb below the knee while exposing the patella of the knee. The chamber is adapted to receive and contain a thermal fluid for abutting contact with the encompassed portion of the limb. The chamber preferably is divided into inner and outer compartments with the thermal fluid received by and contained in the inner compartment for abutting contact with the encompassed portion of the limb. An open-cell urethane foam material is contained in the outer compartment for insulating the underlying inner compartment and for enhancing uniform conformance to the limb. The walls of the inner compartment in the distal area of the arms are restrained from movement away from each other so as to restrict expansion of the inner compartment in the arm distal areas and to cause a greater amount of thermal fluid to remain in the proximal arm area and in the transverse portion to lessen venous constriction in the limb below the knee. A hand-held pump is provided for pressurizing the outer compartment to force the inner compartment with the thermal fluid against the areas of the limb being treated. An elastic strap connects the arms around the limb below the knee to minimize venous constriction.
