Abstract
A design and method of operation are disclosed for a fluid control conduit of a blood reservoir. The venous blood inflow conduit includes a fluid control nozzle and a base. When assembled together the nozzle and base form a trap feature which prevents reflux of air or other gas upwardly into the nozzle of the conduit. As a result, during use of the reservoir the conduit normally runs full of venous blood and turbulence of the blood is prevented. In addition, the conduit also functions to divert the downward flowing venous blood in the nozzle into the base at an optimum fluid velocity to overcome the buoyancy effect of air or gas bubbles within the blood.
