Claims14
A therapeutic device, comprising:
- a sleeve for covering a portion of a patient's body and having a pair of opposed flexible liquid impervious walls defining a space to receive liquid, said sleeve having a sheet of substantially nonabsorbent open cell foam in the space between said walls;
- means for circulating a liquid through said space of the sleeve;
- and
- means for selectively heating and cooling the circulated liquid at a location remote from the sleeve comprising a container having opposed metallic walls defining a chamber, a plurality of thermoelectric devices arranged on the outer surfaces of both walls, each thermoelectric device having one side in contact with a chamber wall, heat sink means on each side of the container, each thermoelectric device having a side opposite said one side in contact with said heat sink, a D.C. power supply, and control means for selectively directing current through said thermoelectric devices in one direction, whereby liquid in said chamber is caused to be heated, and in a direction opposite said one direction, whereby liquid in said chamber is caused to be cooled.
