SOFTSHELL RESERVOIR WITH INTEGRATED CARDIOTOMY RESERVOIR

摘要

A softshell blood reservoir (10) incorporates an integral flexible cardiotomy section (12) in which a filter/defoamer unit (25) is supported in a semirigid cage (20). The reservoir (10) also incorporates a storage section (16) and a mixing section (18). The three sections (12, 16, 18) can selectively communicate with each other. Cardiotomy blood is supplied to the cardiotomy section (12) and venous blood is supplied to the mixing section (18). The storage section (16) holds varying amounts of cardiotomy blood to maintain a constant mixed blood output from the mixing section (18). Only the filter/defoamer unit (25) and the mixing section (18) need be primed.
