Abstract: A system for alternately applying and relieving pressure of predetermined portions of a foot of a user. The system includes a plurality of inflatable chambers, located at predetermined locations, corresponding to the predetermined portions of the foot and a pump. The system also includes a center pneumatic valve, coupled with the pump and with the inflatable chambers, for receiving air from the pump and inflating at least one of the inflatable chambers. The system further includes a pneumatic valve assembly, coupled with the center pneumatic valve. The pneumatic valve assembly is coupled with at least a respective one of the inflatable chambers. The pneumatic valve assembly is moveable between two positions, and changes position when a predetermined pressure value is achieved in the corresponding inflatable chamber. When the pneumatic valve assembly changes position, the center pneumatic valve changes position, thereby inflating another inflatable chamber.

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.

Abstract: A self-powered compression device for use in promoting circulation, said device embodying a plurality of inflatable sleeves arranged sequentially for applying compression to a body or limb and which further comprises a pump, a piping system and a bandage or boot to enclose the device in its entirety. A method for using self-generated pressure in promoting circulation in conditions including but not limited to, lymphatic and traumatic edemas, venous disorders, limb ulcers, varicose veins, muscle fatigue, sports medicine, cellulite treatment, diabetic feet, feet massage for recreation or cosmetic enhancements.
