Abstract

An apparatus is for use with a temperature controlled fluid circulating device which apparatus controls the temperature of an area of the body. The apparatus includes a fluid circulating blanket having connecting hoses for connection to the fluid circulating device. The fluid circulating blanket is installed within the interior of a support envelope surrounding the fluid circulating blanket. The fluid circulating blanket and surrounding support envelope respectively include parallel elongated portions with connecting portions therebetween to provide an overall U-shape with an elongated opening between the parallel elongated portions of each of the blanket and support envelope. The apparatus includes straps for securely positioning the support envelope, with the fluid circulating blanket therein, with the inside surface of the support envelope against the area of the body. The inside surface of the support envelope includes cloth material while the outside surface of the support envelope includes insulation material.
