Abstract
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.
