本文介绍了一种独特的磁悬浮轴流血泵从功能原型到适合动物试验的泵的小型化过程。通过COMSOL三维有限元分析和实验验证，对泵的混合磁悬浮轴承进行了小型化，减小了磁件之间的轴向间距，减少了泵机械部件中的多余材料。实验结果表明，泵的性能基本不变，较小的尺寸导致了小牛急性泵植入的成功。
This article introduces a unique miniaturization process of a magnetically levitated axial flow blood pump from a functional prototype to a pump suitable for animal trials. Through COMSOL three-dimensional finite element analysis and experimental verification, the hybrid magnetic bearings of the pump have been miniaturized, the axial spacing between magnetic components has been reduced, and excess material in mechanical components of the pump was reduced. Experimental results show that the pump performance was virtually unchanged and the smaller size resulted in the successful acute pump implantation in calves.
