Abstract:
1. A compression device for the limb of a mobile patient comprising: an inflatable sleeve adapted to surround the limb; a conduit attached to said sleeve for delivering fluid to said sleeve; and a portable, wearable controller attached to said conduit that generates and controls the flow of fluid in the device, wherein the sleeve consists of a leg cuff and a foot cuff, and the leg cuff consists of only three cells each consisting of a single compartment, a gaiter cell, adapted to wrap fully around the lower limb in the region closest to the ankle, a mid-calf cell, adapted to wrap fully around the lower limb above the region occupied by the gaiter cell and an upper cell adapted to wrap fully around the lower limb in the region between the mid-calf cell and the knee and wherein each cell is monitored by a sensor and the cells are pressurized to different pressures wherein the upper cell and mid-calf cell alternate in providing compression so that the mid-calf cell provides higher compression than the upper cell when blood is being expelled from the leg and the upper cell provides higher compression than the mid-calf cell to prevent backflow at rest.
