Abstract
A venous reservoir for use in cardiotomy bypasses comprising a flexible, variable capacity bag having a vertical seal positioned between the outlets and inlets along the lower seal line. The vertical seal line is positioned off-center such that the velocity of blood decreases as it passes the top of said seal line and towards the lower outlet to increase the removal of bubbles from the blood. All ports serving the reservoir are constructed without internal projections into the reservoir to decrease the possibility of thrombosis. The upper and lower edges of the reservoir are looped to receive horizontal rods slidably attached to a vertical support. Adjustment of the distance between the rods varies the volume possible within the reservoir.
