Abstract
A volume controlling support for a flexible venous reservoir that permits the reservoir to have a clear flow passage from its inlet to its outlet which is visible and accessible to the perfusionist. The portion of the reservoir through which the major part of the blood flow is occurring can be manipulated if necessary, particularly for the purpose of manipulating the reservoir to improve the clearance of air bubbles in the blood. Preferred embodiments also enhance the convenience for the perfusionist by permitting right-handed or left-handed operation, and by providing an approximate read-out of the volume of blood contained in the reservoir.
