Abstract
The invention is an innovative hybrid venous reservoir designed to receive and store blood during cardiopulmonary bypass (CPB), the hybrid venous reservoir consisting of an air purging chamber that limits air in the venous blood entering the air purging chamber from exiting the air purging chamber in combination with a compliant storage chamber with at least one pliable wall, the combination providing a large volume capacity while limiting the area of the blood-air interface to that of the air purging chamber.
