ABSTRACT:
The present invention relates generally to compression devices and, more particularly to a method using air flow to close the exhaust valve in each sleeve, allows air to fill the sleeve to a pretuned pressure, and finally deflating the sleeve by letting the air flow through the outlet valve. This creates a pressure gradient and a pneumatic cycle means that facilitates the massaging movement on the limb towards direction of the heart. The magnetic force in valves is uniquely adapted for controlling low-pressure compression. A magnetically adjustable valve is adapted for use in a compression device to control and regulate low to very low pressures and comprising of a movable magnetic part and a metal part, defining an air gap there between. A self-powered device causes the magnetic part and the metal part to move away from each other and control the air access and pressure in the valve body, while creating a gradient of decreasing pressure, the highest pressure being in the first air chamber to the lowest pressure in the last air chamber.
