Pneumatic compression devices and garments for the prevention of deep vein thrombosis

摘要

A pneumatic compression device for non-invasive external intermittent pneumatic compression system used as prophylaxis for reducing the incidence of Deep Vein Thrombosis (DVT). The system consists of a pneumatic compression pump, valves for control of air flow, a pressure sensor, and a controlling circuitry. The controlling circuitry receives input from the pressure sensor and switch ON/OFF one or more control valves based on the pressure sensor input to dynamically controlling the pressure of the regulated compressed air flow.
