摘　　要：目的:通过理论与实践相给合,探讨故障树分析(FTA)法应用于血液透析机水路系统的风险分析,从而为血液透析机的维护维修提供指导与参考。方法:在收集上海市3家三级甲等医院血液透析室2008年血液透析机维护维修数据的基础上,通过建立故障树、定性分析和定量分析,对血液透析机进行风险分析。结果:通过分析与计算,找出了造成血液透析机因故障而带来风险的主要原因为:除气泵故障和电磁阀故障。结论:应用FTA能为开展血液透析机的预防性维护和降低风险提供参考依据,增进医院临床工程师对血液透析机进行风险管理的意识,促进风险管理活动的展开。Objective： This paper applies fault tree analysis into risk analysis of hemodialysis machine waterway failure through the theory and practice to provide the guidance and reference for repairing and maintenance of hemodialysis machine. Methods： Based on the repair and maintenance of hemodialysis machine data of three top three hospitals in Shanghai in 2008, we established the fault tree and conducted qualitative and quantitative analysis for risk analysis of hemodialysis machine. Results： The main reason of hemodialysis machinefailure risks was pump failure and the solenoid valve failure. Conclusion： Application of FTA method can provide reference in preventive maintenance and reducing risk for hemodialysis machine, promoting the expansion of riskmanagement activities for clinical engineers.
