ABSTRACT:
A blood aspirator is composed of a suction circuit adapted to receive a flow of blood, a sensor associated with the suction circuit for generating a signal relating to the presence of bubbles in aspirated blood in the suction circuit, a variable speed pump coupled to the suction circuit and adapted to pump blood through the suction circuit, and a controller for controlling the speed of the pump. The controller causes the pump to adjust the blood flow through the suction circuit so that a predetermined, nonzero concentration of bubbles flows through the suction circuit.
