ABSTRACT:
A medical drainage and irrigation system employs a reversible peristaltic pump to perform both drainage and irrigation. A motor control system independently controls the duty cycle and flow rate during drainage and irrigation using an electronic control to transfer the pumping direction between drainage and irrigation. A loop comprising a flow control valve assembly and external tubes connected thereto may be removed as an assembly for cleaning or discard.
