In order to reduce the blood damage of the oxygenator at work, the Taguchi method combined with finite element analysis was used to optimize the blood flow channel structure of the oxygenator with multi-objective optimization. The order of the degree of the influence of each parameter on blood damages was obtained and the optimal blood flow channel structure was determined. The results show that the most critical control factor affecting blood damages is the diversion component at the end of the blood inlet under this design condition. With the increase of the length of inlet and outlet pipes, the blood damage is reduced, but the processing difficulty is increased. The standard hemolysis index value of the oxygenator after optimization is reduced by 0.001284g/100L compared to before optimization. This research provides a reference to the optimal design of oxygenator and other medical devices.
