Abstract
A control system for controlling a quantity of blood in a blood reservoir (10) of a perfusion system supplied by a venous line (V), wherein a pump (20) circulates blood from the blood reservoir (10) through an outgoing line (A), comprises a venous flow sensor (22) to measure a venous blood flow rate, an outlet flow sensor (24) to measure an outgoing blood flow rate, and a controller to control the pump (20) to prevent the outgoing blood flow rate from exceeding the venous blood flow rate. Thereby, a decrease of blood in the blood reservoir (10) can be arrested.
