Abstract
A device for applying cryogenic compression for use in diminishing hemorrhage and edema in acute trauma of body extremities is formed by a sleeve having a plurality of adjacent non-communicating cryogenic chambers and a plurality of coextensive pressure chambers, there being a pressure chamber for each cryogenic chamber. There are fill openings for each cryogenic chamber and inlets for each pressure chamber. A pump is connected to all of the pressure chamber inlets to apply intermittent pressure to one or more of the pressure chambers to thereby apply intermittent cryogenic pressure to an area of a body extremity coextensive with one or more of the cryogenic chambers.
