The present invention is a vehicle having a mobile extremity pumping apparatus mounted thereon. The mobile extremity pumping apparatus comprises a control module, a driver module and one or more compression units. A two-layer bladder assembly is positioned between the inner layer and the outer shell comprising precompression and compression bladder layers. The precompression bladder layer extends longitudinally along the person's extremity with the individual bladders each wrapping around and arranged sequentially along the extremity. The precompression bladder layer is surrounded by a compression bladder layer mounted between the precompression bladder layer and the outer shell. A pump in the driver module compresses the media, which may be water, air, or similar media, and directs the compressed media to a manifold for distribution to each valve in the driver module. A control processor unit in the control module is connected to each valve in the driver module and further connected to each pressure sensor in the driver module to monitor the pressure in each bladder in the two-bladder layer assembly.

Mobile extremity pumping apparatus

A portable, hydraulic extremity pump apparatus for treatment of edema is disclosed. The apparatus consists of a flexible compression unit that wraps around an individual's extremity. The compression unity has a plurality of prefill bladders each containing a separate compression bladder. The bladders are connected to a hydraulic pump through valves. Pressure sensors are connected to prefill bladders. The valves, the pump and the pressure sensors are all connected to a programmable control processor to operate the valves and pump and to monitor the bladder pressures. The valves to the prefill bladders are closed at an appropriate pressurization and the pump is shut down to mold the compression unit around the extremity. The occurrence of edema may then be detected by the monitoring of the pressure in the prefill bladders. Upon detecting an increase in pressure, indicating edema, the control processor activates the pump and opens the valves connected to the compression bladders in a sequential manner to create a sequential pressurization and a wave of compression moving proximally on the extremity. The pressure sensors and control processor continue to monitor the pressures after each wave of compression.
