A compact portable system designed for the noninvasive treatment and prevention of venous disorders and sequelae (lymphatic, arterial, trauma) by facilitating better vascular flow, as well as minimizing venous stasis during/after surgery and immobilization. It applies sequential pressure to a patient's arm or leg to promote venous blood flow and typically consists of an electrically-powered compression pump, control/timing mechanism, rechargeable batteries, and tubing that connect to an integral cuff or pneumatic stockings that inflate and deflate sequentially. It is normally available [non-prescription] over-the-counter (OTC) for home-use and/or for hospitalized/institutionalized patients.
