【摘要】：现有的外磁驱动植入式轴流血泵,由于植入环境、受驱动力不均匀等因素会产生振动。本文通过对单个红细胞进行建模,仿真分析单个红细胞在边界振动流场中的变形与受力,并与红细胞在血泵中遭受机械损伤的机制相结合,研究边界振动流场对红细胞损伤的影响。研究结果表明,在边界振动流场中红细胞的形状变化情况、受力状况和周围速度场等因素均会导致红细胞损伤。通过对上述内容的研究,本文期待可为改善血泵的溶血现象提供理论依据。
[Abstract]:The existing external magnetic drive implantable axial bleeding pump will vibrate due to the non-uniform driving force and other factors. In this paper, the deformation and force of single red blood cell in the boundary vibration flow field are simulated and analyzed by modeling the single red blood cell. The effect of boundary vibration flow field on erythrocyte damage was studied by combining with the mechanism of erythrocyte mechanical injury in blood pump. The results show that the shape of red blood cell changes in the boundary vibration flow field. The stress condition and the surrounding velocity field will cause erythrocyte damage. Through the study of the above contents, we hope to provide a theoretical basis for improving the hemolysis phenomenon of the blood pump.
