DVT prevention apparatus and monitoring method

摘要

An inflatable garment for applying compression to the limb of a patient has two inflatable chambers (1, 2) on respective limbs of a patient. Both the lower and upper chambers are directly connected sequentially to a common source of inflation. A non-return valve (9) prevents any deflation of the first chamber when beginning to inflate the second chamber. A differential pressure sensor (31, 32) connected between garments on the two limbs of a patient indicates by a display device 34 the polarity of the pressure reading which of the garments is being monitored.
