Abstract
An inflatable/deflatable compression device, such as, a sleeve or cuff for use in simulating blood circulation in the limbs. The compression device is designed for use with a source of cyclical fluid pressure to provide alternating inflation and deflation cycles of the device. The compression device has at least one inflatable/deflatable fluid chamber. A safety bleed hole fluidly couples the interior of the fluid chamber to the exterior so that fluid pressure will be released from the at least one fluid chamber in the event that the source of cyclical inflating and deflating fluid pressures does not cycle to its deflating mode.
