ABSTRACT:
A system is provided for promoting the circulation of blood through a patient's extremity. An outer retaining garment confines and constrains an inflatable air bag around the patient's extremity that is undergoing treatment. Compressed gas is supplied to and exhausted from the air bag to inflate and deflate the air bag in order to provide compression and decompression of the patient's extremity. Flow passages in the air bag extend from the gas inlet to selected distribution points within the air bag to provide uniform inflation of the air bag substantially simultaneously throughout its length. The rate of compression and decompression of the patient's extremity is controlled and phased to the patient's heart beat in order to promote the circulation of blood through the extremity.
