ABSTRACT:
An extracorporeal blood circuit comprises a generally cylindrically shaped blood reservoir; a generally cylindrically shaped oxygenator arranged coaxially and adjacently below said reservoir; and a generally cylindrically shaped heat exchanger attached coaxially and adjacently below said oxygenator. The reservoir encloses an upper defoamer and multiple filter element adapted to receive cardiotomy blood within the interior of said upper element and to discharge treated blood to said reservoir; and a lower defoamer and filter element adapted to receive arterial blood within the interior of said lower element and to discharge treated blood to said reservoir; and has a lower blood outlet. The oxygenator has an inlet adapted to integrally receive blood directly from the outlet of said heat exchanger and an outlet adapted to return the oxygenated blood to the patient.
