MEDICAL-THERAPEUTIC DEVICE

摘要

A device (1,2) for sustaining the operation of the blood vessels in a limb of the human body has different chambers (8,9,10) in contact with the limb and filled with a fluid, which is pulsatingly pressurized and decreased in pressure. The invention improves such known devices in order to avoid rapid backflow of venous blood towards the extremity of the limb during decrease of pressure in said chambers. This is obtained by applying only a small pressure drop in one or more proximal chambers (10 and possibly 9). The pulsations may be generated by a foot pump being a chamber (3) under the foot of the patient, or by external pressurizing and pulsating means. The device may be embodied as a boot (1) for a human leg or be mounted inside such a boot.
