초록

A combined venous and cardiotomy blood reservoir is provided that includes a rigid shell having a top, a bottom, and a continuous side wall. The top and bottom walls are connected to the continuous side walls so as to define a reservoir for venous and cardiotomy blood. A double column structure is provided within the blood reservoir, the first column for receiving and degassing venous blood, the second for receiving, filtering and defoaming cardiotomy blood. The venous blood filtering and defoaming components can include a top venous screen plate, a bott...
