摘要：
A cardiotomy and venous blood reservoir, including a housing assembly, a venous inlet port, a venous sub-assembly, a cardiotomy inlet port, and a cardiotomy sub-assembly. The housing forms a chamber. The venous sub-assembly includes a downtube and a bowl. A diameter of the downtube lumen increases to a downstream end. The bowl forms a floor surface for receiving flow from the lumen. The cardiotomy sub-assembly includes a dish and an inner post. The dish defines an aperture. The inner post extends from the dish and forms a guide surface received within the central aperture and forming an undulating curvature increasing to a diameter greater than the diameter of the central aperture. Cardiotomy liquid drops from the dish fall on to the undulating, closely positioned guide surface with minimal splashing.
