Abstract:
An improved therapeutic device for applying cooling to a body joint to speed healing comprises a reservoir of chilled fluid connected to a container in heat conducting relation with the joint to be chilled by supply and return lines. Fluid is continually recirculated by convection, employing the thermosiphon principle, such that the fluid is recirculated by energy provided by the patient's body heat. Check valves may be provided in one or both of the supply and return lines, preventing reverse flow, and also so that motion of a patient's body joint within the container further motivates the recirculating flow.
