摘要:
电磁搏动式血泵是基于电磁感应原理制作而成的，长时间通电工作会引起血泵升温。如果血泵温度过高会使血泵损坏，甚至可能使泵内循环血液温度过高，对血液成分造成破坏甚至威胁生命，因此研究电磁搏动式血泵温度，对其进行温度场分析是必要的。通过使用有限元分析软件对血泵进行温度场分析，可以直观观察血泵工作温度。仿真结果表明，在设定电磁搏动式血泵工作1 h情况下，血泵温度最高处在驱动绕组处，最高温度为100.3 ℃，泵内与37.0 ℃循环血液接触面的温度变化不大,最高温度为37.5 ℃，因此电磁搏动式血泵不会对血液成分造成破坏，但是需要对驱动绕组进行降温处理以免破坏血泵,对循环血液造成影响。
Abstract:
Abstract: The electromagnetic pulsating blood pump is made based on the principle of electromagnetic induction, and the long-term power-on work will cause the blood pump to heat up. The high temperature of the blood pump will damage the blood pump, and raise the temperature of the blood circulating in the pump, causing damages to the blood components or even life-threatening. Therefore, it is necessary to pay close attention to the temperature of the electromagnetic pulsating blood pump and analyze its temperature field. By analyzing the temperature field of the blood pump using the finite element analysis software, the working temperature of the blood pump can be observed intuitively. The simulation results show that when the electromagnetic pulsatiling blood pump is set to work for 1 h, the highest temperature of the blood pump which is 100.3℃ is found at the drive winding, and the temperature of the contact surface between the pump and the circulating blood at 37℃ does not change much, which is 37.5 ℃ at the highest. Therefore, electromagnetic pulsatiling blood pump will not cause damage to the blood components, but the drive winding needs to be cooled to avoid damages to the blood pump and affecting the circulating blood.
