the pneumatic lines are preferably routed within the compression sleeve portion 11 both to minimize exposure to potential damage and for patient comfort and convenience avoiding dangling lines and direct contact pressure points from lines routed on the inside surface of the compression sleeve the lines also may be alternatively routed such as on the outside or inside surfaces of the compression sleeve as long as they connect the bladders with the compressor to permit control of bladder inflation at the bottom of the pouch 1 is a coupling device 3 which securely connects the concealed and or contained pneumatic lines connected to each of the three inflatable chambers 2 4 5 to the compressor and controller unit preferably the coupling 3 is located within the pouch for its protection and to facilitate easy removal and insertion of the compressor and controller unit from to the pouch 1 the coupling device 3 is not limited to a bottom of the pouch location but may be located at any desired location including inside outside or near the pouch 1 or on the on the sleeve itself is a pouch is not present fig2 illustrates the compressor and controller unit 20 of this embodiment the compressor and controller unit 20 integrates a compressor section and a controller section into a common housing however these units may be housed in separate housings as long as the controller is coupled with the compressor section to control inflation and deflation of the compression bladders the compressor and controller unit 20 of this embodiment has two parts upper removable rechargeable battery housing 30 and lower compressor housing 40 other arrangements such as.
