ABSTRACT:
A pump for oscillating a fluid into and out from a body area. The pump forms a fluid chamber for holding the fluid, and comprises a piston for forcing fluid outward from the fluid chamber and into the body, and for drawing fluid inward from the body and into the fluid chamber. A motor is connected to the piston, and a control circuit is connected to the motor to control movement of the piston. The control circuit has a first state actuating the motor to force the fluid into the body, and a second state actuating the motor to draw the fluid from the body, and the control circuit may be adjusted to vary the rates at which fluid is forced into and drawn from the body.
