ABSTRACT:
A method and apparatus for sequentially inflating and deflating a compression device or the like to stimulate blood flow and prevent deep vein thrombosis. The apparatus includes an air compressor with a regulator valve providing fast inflation of such device to a pressure of approximately 60 mm Hg (1.2 psi) within 3 to 7 seconds. A pulse timer and a delay timer in the system are coupled together for actuating the compressor and a pressure relief valve to peak and maintain a pressure in the device for a measured period of time.
