摘要： A portable pump (10) for use with a gradient compression bandage (11) generally comprises a selectively actuable source of pressurized fluid (22) in communication with a plurality of outlets; a plurality of selectively actuable latching valves (17-20) interposed between the fluid source and each outlet; and a controller (21) for controlling electrical power supplieS to the fluid source and the latching valves, thereby selectively actuating the fluid source and the latching valves. Portability is achieved through battery power conservation means such as utilization of latching valves having an open state and a closed state and adapted to require electrical power only in transition between states and utilization of an electrical controller adapted to selectively switch power to the air compressor and the latching valves as required. The fluid source may also comprise a one-way check valve (23) for preventing back flow and leakage of the pressurized fluid through the air compressor. A pressure sensor (27) for obtaining a pressure measurement at each fluid outlet is also selectively powered by the controller. A power supply system (45) allows full battery operation of the portable pump. This system comprises a battery recharge circuit (46) adapted to automatically discontinue battery charging upon reaching of a three-hour time limit for charging, detection of a negative battery charge voltage curve or measurement of an excessive battery temperature.
