ABSTRACT:
A blood reservoir includes a blood tank, a blood accumulator connected in fluid communication with an outlet of the tank for receiving blood from the tank, and a pumping device for driving the accumulator to displace blood out of the accumulator. The accumulator typically in the form of a flexible bag is adapted to store blood in an amount proportional to the volume of blood in the tank when the volume of blood in the tank is reduced below a predetermined value. The pumping device is operated for intermittent blood delivery and can regulate the amount of blood displaced out of the accumulator.
