ABSTRACT:
A variable capacity reservoir assembly for use in a blood oxygenation system which includes a collapsible reservoir and an elongated unitary clamp. The reservoir is of fluid-impermeable flexible material and includes an expandable portion capable of holding a predetermined maximum volume of blood. The reservoir also includes one main blood inlet and one main blood outlet. The clamp is bifurcated and slidably engages the reservoir, preferably between the inlet and the outlet and grasps the expandable portion so as to control the expansion thereof and thereby control its blood holding capacity.
