Patent ID: 7258676

Claim:
A self-powered compression device comprising: a foot pump, said pump connected to a pneumatic pressure control system, wherein atmospheric air is drawn into said system at each step, the pneumatic pressure control system comprising a plurality of inflatable sleeves, each of said sleeves connected to valve bodies, each of said valve bodies having a set of inlet magnetic check valves and outlet exhaust valves for connecting to the compressed air source and supplying compressed air to the inflatable sleeves, wherein the pressure in said inflatable sleeves is controlled by a magnetically operated check valve to provide suitable pressures for massaging and promoting health, the self-powered pressure device further comprising an inlet valve, wherein each step brings new atmospheric air into the device, inflating and deflating the sleeves in continuous cycles according to pre-tuned pressure in each of the sleeves and wherein the magnetically operated check valve includes: a valve body having an orifice at one end and a magnetic cylinder at the other end, wherein the magnetic cylinder is attached to the valve body by a screw member, the screw member is positioned adjacent to a magnetic ring, and a metallic ball having a diameter greater than the diameter of the valve body is placed between the orifice and the magnetic ring.
