Blood reservoir with visible inlet tube

摘要

A blood reservoir adapted for use in an extracorporeal circulatory support circuit. The blood reservoir includes a visible inlet tube that extends vertically outside the housing of the reservoir to allow visual observation of venous blood flowing in the inlet tube. The inlet tube is releasably held generally adjacent the top of the housing to allow the reservoir to be converted between top and bottom mounted venous blood inlets with a single inlet, as well as permitting the inlet tube to be moved to a position extending downwardly from the reservoir to allow draining the reservoir through the inlet tube after surgery. A generally funnel-shaped inlet portion may be provided in the inlet adjacent the chamber to decelerate blood before it enters the chamber, and a diverter cone may be provided over a venous inlet portion to divert the incoming blood.
