Abstract:
1. A device for handling blood in extracorporeal blood circulation, comprising at least one oxygenator; at least one heat exchanger which together with said at least one oxygenator forms an oxygenator/heat exchanger structural unit having an inlet and an outlet, wherein said inlet and outlet into said oxygenator/heat exchanger unit has a blood flow cross-section of at least equal to 120 mm 2 minimizing shear stresses action on the blood; and a blood filter having an inlet provided on one side and coupled to said structural unit directly without connecting lines narrowing said blood flow cross-section and having a blood flow cross-section which is equal to said blood flow cross-section of said structural unit, wherein said blood flow cross-sections are at least equal to 120 mm 2 , said filter also having an outlet provided on an opposite side for delivery of the blood, wherein said oxygenator, said heat exchanger, and said blood filter are connected with one another directly without connecting lines narrowing said blood flow cross-section, wherein said heat exchanger is composed of heat exchanger fibers and is integrated with said oxygenator, so that said oxygenator and said heat exchanger together form one structural part and the heat exchanger fibers are integrated in said oxygenator.
