Abstract
A blood circulation apparatus includes a suction wand for receiving blood from a patient, a reservoir for collecting received blood, a flow path between the suction wand and the reservoir, and an anticoagulant pump and line for introducing anticoagulant into the flow path upstream of the reservoir. Sensors detect pressure in the flow path and in the anticoagulant line, and transmit corresponding pressure signals to a controller that regulates anticoagulant introduction as a function of the pressure signals.
