Abstract
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 encompasses a portion of the limb above the knee and the depending arms encompass the limb along the sides of the knee and a portion of the limb below the knee while exposing the patella. The chamber is intended to 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 contained in the inner compartment. An open call urethane foam material is contained in the outer compartment for insulating and 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 area and in the transverse portion to lessen venous constriction in the limb below the knee. An elastic strap con…
