Abstract
The automatically controlled pump includes a battery-powered motor with a housing, a pump in a housing with input and output ports. A switch turns ON and OFF the motor due to fluid pressure at the output, Sometimes, the pump housing is below the motor housing and below the battery housing. The input port is beneath the impeller and the output port. A version also includes a manual ON aid OFF switch actuated by an operator and a check valve limiting upstream flow of the pressurized fluid. The fluid pressure sensitive switch is mounted downstream of the check valve. An irrigation surgical kit includes the automatically controlled pump, a spike for a fluid source bag, fluid lines and an operator controlled valve unit disposed at or near the surgical site. The method monitors fluid pressure at or near the pump's output and turns ON and OFF the motor.
