摘要
心力衰竭是各种心脏病患者最主要的死亡原因。近年来,终末期心力衰竭的治疗日益成为临床心血管医师所面临的巨大挑战。由于药物治疗和常规外科手术的局限性,以及供体心脏的缺乏,促进了心脏机械辅助循环装置的快速发展。电机学、机械工程学、流体力学、材料学和医学等多学科的联合研发,探寻可长期植入式新型叶轮血泵已成为当今国内外的研究热点。轴流血泵具有结构简单、重量轻、流量大、效率高、易植入和取出等优点,同时无需安装人工瓣膜,减少了血栓形成的几率。与离心泵相比较,轴流血泵体积更小,血液破坏程度更轻。目前轴流血泵的研究已经成为心脏外科和生物医学工程领域关注的焦点。现对轴流血泵的工作原理、特点和当前轴流血泵研究中面临的一些关键技术问题进行综述。
Among all kinds of heart diseases,heart failure is the leading cause of death.In recent years,the treatment of terminal heart failure has increasingly become a great challenge to cardiovascular clinical physicians.The limitations of routine medical therapy and surgical interventions,and the shortage of donor hearts have led to the rapid development of mechanical circulation support devices.As the joint research and development of electric machine,mechanical engineering,fluid mechanics,materials science,medical science and some other related subjects,exploring a new type of long-term implantable blood pump has become a hot issue.Axial flow blood pump has the advantages of simple structure,light weight,high flow and efficiency,easy implantation and removal,and at the same time,it does not need to install artificial valves,which can greatly reduce the risk of thrombosis.Compared with the centrifugal pump,axial flow blood pump is smaller and causes much less damage to the blood.At present,axial flow blood pump research has become a focus in cardiac surgery and biomedical engineering field.This article is going to review the operation principles and characteristics of axial flow blood pump,and some key technical issues of current axial flow blood pump research.
