Abstract:
1. A compression treatment system comprising: a first bladder supported about a limb; a second bladder supported about the limb, the bladders being in fluid communication with a fluid source and the bladders being inflated such that the first bladder is inflated for a first time period and the second bladder is inflated for a second time period, the second time period and additional time periods being initiated within the first time period; and a pneumatic control circuit located at a controller housed separately from the inflatable bladders, the pneumatic control circuit including the controller, a single pressure sensor, a single check valve, the fluid source and a plural of solenoid valves, the single pressure sensor located between the fluid source and solenoid valves and communicating with the first bladder and the second bladder, and the single check valve operably connected to the fluid source and located between the fluid source and solenoid valves, wherein the single check valve prevents leakage out of the first bladder, and the single pressure sensor measures bladder pressure in cooperation with the controller to calculate venous refill time at the first bladder.
