PUMP/OXYGENATOR WITH BLOOD RECIRCULATION

摘要

A system of processing blood during a surgical procedure includes a centrifugal blood pump (16) with an inlet (16A) and an outlet (20), a means for oxygenating the blood and a means for recirculating a portion of the oxygenated blood to the inlet (16A) of the blood pump (16). The volume of blood recirculated through the system can be controlled by a flow control means. Recirculation of a portion of the blood reduces the cost and size of the system.
