ABSTRACT:
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 bottom venous screen plate or stand and a perforated venous cage captured therebetween. The venous column is of generally D-shape and has a double screen structure including an inner microscreen and an outer microscreen received respectively on the inside and outside of the perforated venous cage. The cardiotomy blood filtering and defoaming components can include an inner, first defoaming element, a core support frame, a depth filter, an outer, second defoaming element, and a filter covering sock.
