摘要:
 目的:通过对轴流式血泵电机进行温度场仿真分析,得到其对血液和组织的损伤情况,并探讨降低血液和组织温升的策略。 方法:利用ANSYS对电机进行瞬态温度场仿真,利用FLUENT建立血液动态温度场模型,对血液和组织的温度变化进行研究。 结果:根据电机运转稳定时的温度分布云图,可知定子绕组和定子铁芯的发热温度较高;通过分析下泵壳和上泵壳的温度场,得到血液和组织的温升情况;根据血液动态温度场模型,得到血液在流动过程中的温度变化规律。 结论:可以通过改变电流大小来降低血液和组织的温升,当电流值为0.9 A以下时,温升对血液和组织不造成损伤。此分析结果可为临床应用和血泵优化提供理论基础。
Abstract:
 Abstract: Objective To analyze the damages of increased temperatures around an axial flow blood pump motor to blood and tissue by simulating the temperature field of the motor and explore the countermeasures. Methods By simulating the transient temperature field of the motor using ANSYS and constructing a dynamic blood temperature model with FLUENT, we analyzed the temperature changes of the blood and tissue around the axial flow blood pump motor. Results The temperature distribution cloud map when the motor ran stably revealed relatively high temperatures on the stator winding and stator. The temperature rises of the blood and tissue were obtained by analyzing the temperature fields of the bottom and top shells of the motor. The pattern of blood temperature variation during motor-driven blood flow was derived from the dynamic blood temperature model. Conclusion The temperature rise of the blood and tissue around the axial flow blood pump motor can be reduced by adjusting the current, and the temperature rise does not cause detrimental effects on the blood and tissue when the current is maintained below 0.9 A. This finding provides a theoretical basis for clinical application and parameter optimization of axial flow blood pump.
