More Information
Summary:A cardiotomy and venous blood reservoir (20) including a housing assembly (22), a downtube, and a bowl. The housing assembly forms a chamber. The downtube extends from an inlet port to a downstream end within the chamber. A diameter of the tube lumen increases to the downstream end. The bowl forms a floor surface shoulder (60), intermediate segment, and protrusion. The shoulder circumferentially surrounds, and is spatially above, the downstream end. The intermediate segment extends radially inwardly and downwardly from the shoulder to a bottom face. The protrusion extends radially inwardly and upwardly from the bottom face to a center that is aligned with the lumen and below the downstream end. The flared inner diameter of the lumen reduces fluid velocity as venous blood enters the reservoir. The bowl floor surface gently receives the incoming venous blood at the protrusion, and smoothly guides the blood flow.
