摘要： A hollow fiber type blood oxygenator having an integrated and improved heat exchanger having a generally conical housing and core member between which a helically wrapped conduit is situated. The conduit has a plurality of parallel flutes. A housing and core member are formed with helical recessed regions which conform to the conical helix defined by the tubing or conduit. The tubing is formed with flattened opposing surfaces which mate with the corresponding recesses in the housing and core member. The mating on the flats on the tube or conduit to the corresponding flats in the recessed regions of the housing and core member allows a substantially tighter and more uniform fit which minimizes the dynamic blood priming volume.

摘要： A venous reservoir for use in cardiotomy bypasses comprising a flexible, variable capacity bag having a vertical seal positioned between the outlets and inlets along the lower seal line. The vertical seal line is positioned off-center such that the velocity of blood decreases as it passes the top of said seal line and towards the lower outlet to increase the removal of bubbles from the blood. All ports serving the reservoir are constructed without internal projections into the reservoir to decrease the possibility of thrombosis. The upper and lower edges of the reservoir are looped to receive horizontal rods slidably attached to a vertical support. Adjustment of the distance between the rods varies the volume possible within the reservoir.
摘要翻译：一种用于心切开路旁路的静脉储存器，包括一个柔性可变容量的袋子，该袋子具有位于出口之间的垂直密封件和沿着下部密封线的入口。垂直密封线位于离心位置，使得当血液通过所述密封线的顶部并朝向下部出口时血液的速度降低以增加从血液中除去气泡。用于储层的所有端口都没有内部突出物进入储层，以减少血栓形成的可能性。储存器的上边缘和下边缘环绕以接收可滑动地附接到垂直支撑件的水平杆。杆之间距离的调整可改变储存器内的体积。
