Abstract: A body surface compression device for generating cyclical or constant compressions for medical purposes. Compression is accomplished using pneumatic actuated artificial muscle in combination with a belt placed around a body part. Both artificial muscle shortening and pneumatic expansion are used for compression. A unique useful property of this system is the length-tension characteristic similar to natural muscle which reduces applied compressive force proportionally with the level of volume compression of the body part. This property as well as a uniformly applied compression over the body part allows compression to be accomplished in a way which resembles natural muscle activation and minimizes overall abnormal stress on the body part.

Also incorporated may be a logic circuit capable of utilizing multiple sensing modalities and optimizing the synchronization pattern between multiple phasic therapeutic modalities and myocardial residual mechanical function.

Abstract: A deep vein thrombosis prevention garment includes three (3) chambered polymer having an integral welded filling tube forming three (3) sequentially filled air chambers. The aft chambers receive air from an integrated fill tube attached to pump.

The different internal diameters of the integrated fill tube outlets for each air chamber provide different air flow rates, resulting in staged inflation of air chambers. A membrane panel allows air to escape the sequentially filled air chambers.
