A control system for controlling a quantity or level of blood in a blood reservoir 10 of a perfusion system in which the blood reservoir 10 is supplied through a venous line (V) and a pump 20 is configured to circulate blood out of the blood reservoir 10 through an outgoing line (A). The control system comprising a venous flow sensor 22 configured to measure a venous flow rate of blood in the venous line (V). An outlet flow sensor 24 configured to measure an outgoing flow rate of blood in the outgoing line (A). A controller (not shown) configured to receive as inputs the venous flow rate and the outgoing flow rate, the controller comprising decision logic permitting it to issue a signal to control the pump 20 to prevent the outgoing flow rate from exceeding the venous flow rate so as to arrest a decrease of blood in the blood reservoir 10. |
