血液透析设备的体外循环通路结构原理与常见故障分析处理

The structure principle of extracorporeal circulation pathway and the analysis and treatment of common faults of hemodialysis equipment

通过分析血液透析(HD)设备体外循环通路的结构组成和工作原理,探讨常见故障的排查方法。HD设备是用于肾脏替代治疗的专用设备,设备运行质量对治疗效果和患者生命安全起着重要的作用,因此设备使用人员和维修人员应熟悉体外循环通路的组成,包括血液循环回路和透析循环水路的各部件功能和对透析治疗的影响。当设备出现故障时,可从使用操作规范与否、设备硬件故障、电路元件问题等角度进行逐一分析和排查,制定故障排查的有效路径,提高故障维修的效率。同时在设备日常维护过程中,应加强日常保养和专项维护工作,提升设备质量检测的规范性,不断提升设备临床服务水平。

By analyze the structural composition and working principle of the extracorporeal circulation pathway of hemodialysis(HD)equipment,the troubleshooting methods for common faults were explored.HD equipment is a special equipment for renal replacement therapy,and the operation quality of the equipment plays an important role in the therapeutic effect and life safety.Therefore,equipment users and maintenance personnel should be familiar with the composition of the extracorporeal circulation pathway,including the functions of each component of the blood circulation circuit and the dialysis circulation waterway,as well as their impact on dialysis treatment.When any failure occurs to equipment,analysis and troubleshooting can be carried out from the perspectives of improper use operation,equipment hardware failures,and circuit component problems,etc.to establish an effective path for troubleshooting and enhance the efficiency of failure maintenance.Meanwhile,in the course of daily maintenance,it is required to strengthen daily maintenance and special maintenance,improve the standardization of equipment quality inspection,and constantly improve the clinical service level of equipment.
