目的应用失效模式与效应分析管理方法对刮宫吸引管清洗过程进行分析，完善清洗流程，提高刮宫吸引管的清洗质量。方法组建失效模式与效应分析(Failure mode and effect analysis，FMEA)项目团队，应用失效模式与效应分析管理方法对在清洗刮宫吸引管过程中影响清洗效果的各种因素进行评估、分析，找出原因，制定预防措施。结果应用失效模式与效应分析管理后 RPN 值有明显下降，RPN 值在管理前为1185，管理后为216，下降了81.8%。结论应用失效模式与效应分析改进刮宫吸引管清洗流程，能够有效提高清洗质量，保证刮宫手术患者的安全。“,”Objective To analyze the curettage attract tube cleaning process through management application failure mode and effect analysis method, to improve the cleaning process and the quality of curettage attract tube cleaning. Methods By organizing failure mode and effect analysis (FMEA) project team, failure mode and effect analysis of management method is applied to analyze the effect of various affect factors on cleaning the curettage attract tube and find out the reason to formulate prevention measures. Results After the failure mode and effect analysis is used and managed, the figure of RPN decreases obviously. Before the management, the figure of RPN is 1185; after the management, the figure of RPN is 216, decreased by 81.8%, which improves the cleaning quality. Conclusion Failure mode and effect analysis, as a risk management tool, can analyze and find out all kinds of factors that affect the cleaning quality during the process of cleaning of suction tube for curettage so as to effectively guarantee the cleaning quality.
