容积输液泵的故障分析与质控研究

目的通过对容积输液泵故障数据的分析,制定针对性的质控手段,从而降低故障发生率。方法通过医疗设备管理软件,调用我院2013~2017年近5年容积输液泵的维修记录进行统计,使用拉普拉斯变换公式,对统计数据进行可靠性分析,验证容积输液泵的故障趋势。结合容积输液泵发生故障时间分布和产生原因的特点,对容积输液泵进行多种针对性的质控干预手段,并观察干预后的影响。结果拉普拉斯趋势检验推断2018年容积输液泵的可靠性趋势变差。结论针对容积输液泵故障发生原因制定针对性的质控策略可有效降低容积输液泵的故障发生率,有效保障容积输液泵临床使用的安全性。该方法也可应用于其他医疗设备,为医疗机构设备管理部门更好的结合质控手段,保障医疗设备临床使用安全提供一定参考价值。

Fault Analysis and Quality Control Research of Volume Infusion Pump

Objective To reduce the incidence of fault of volumetric infusion pump by developing specific quality control measures based on the analysis of the fault data of volumetric infusion pump.Methods The maintenance records of volumetric infusion pumps in our hospital in the past five years from 2013 to 2017 were collected using the medical equipment management software,and the Laplace transform formula was used to analyze the reliability of the above statistical data and verify the failure trend of volumetric infusion pumps.According to the characteristics of the time distribution and causes of the failure of the volumetric infusion pump,a variety of targeted quality control interventions were conducted and its effect after intervention was observed.Results Laplace’s trend test inferred that the reliability trend of volumetric infusion pumps deteriorated in 2018.Through the development of targeted interventions,the total number of failures of volume infusion pumps decreased by 68%in 2018 compared with 2017,and the time distribution of failures was stable.Conclusion Specific quality control strategy can effectively reduce the failure rate of volumetric infusion pumps and ensure the safety of clinical use of volumetric infusion pumps.This method can also be applied to other medical equipment,providing a reference value for the equipment management department of medical institutions to better combine quality control means to ensure the safety of clinical use of medical equipment.
