It is an innovative medical device aimed, by generating a wave of pressure and alternating it between the left and right legs, to prevent blood circulation disorders such as venous embolism and deep vein thrombosis. With programmed compressions phase and variable compression responsive to your own performance, as well insights and inspirations for how you can unleash its potential via reverse engineering of what happens naturally when we walk technological features include user interface and performance review, adjustable pressure levels and programmable compression cycles. Applications for the bilateral sequential compression device are varied. It is used in post-surgical rehabilitation, in laid-up patients, and for people who cannot take exercise. Compact, portable, this device can be cheaply and conveniently adapted for use in a variety of settings including the hospital, clinics or at home.
