Circumferential pressure: The inflatable bag applies circumferential pressure to the limb, which can effectively remove the blood accumulation behind the venous valve.
Gradient pressure: The inflatable bag is divided into multiple chambers from the distal end to the proximal end, and the pressure decreases stepwise to ensure the unidirectional flow of blood, avoid damage to the venous valve, and improve the blood flow rate.
Continuous pressure: The inflatable bag is continuously inflated from the foot to the thigh, and then deflated at the same time. It is a cycle of inflation and deflation, so that the blood flow rate is stabilized at a higher level, increasing the venous blood return flow and emptying the legs. venous blood.
