Abstract
A yoke shaped collapsible blood reservoir having first and second yoke legs joined by a yoke midsection. A filter element is positioned in the yoke midsection and across the blood flow path between an inlet at the base of the first yoke leg and a blood outlet at the base of the second yoke leg. An angular blood inlet and a gradual increase in cross-sectional area from the blood inlet to the yoke midsection decreases turbulence and assists in bubble separation.
