电能质量对医疗设备影响的研究

目的研究电能质量下降对医疗设备的故障率和医疗设备安全运行产生的影响。方法2004年1月～2006年12月,对6类共100台分属医院各科室的临床使用率较高的A类设备进行历史性列队跟踪调查,详细记录每台设备每次故障的情况,参照同一时段内电能质量监测的结果进行比较、分析,鉴别、筛选出故障性质归属,取得相关数据。结果受电能质量影响而引发的356次故障中,电源部分的故障次数为159次,控制部分的故障次数为157次,信号通道的故障次数为20次。电力污染导致的电能质量下降,对医疗设备的电源部分和控制部分影响大。结论电力污染使电能质量下降,导致医疗设备故障率增加,对医疗设备的安全运行产生了严重的负面影响,医学工程技术部门对此应高度警惕。

Research on the Influence of Electrical Energy Quality on Medical Equipment

Objective To research the influence of electrical energy quality descend on error rate and safety traffic of medical equipment.Methods During Jan 2004 to Dec 2006,historicity track and research on a hundred Class 'A' equipment in 6 types,which are high usage rate of each section office in attached hospitals,note every error of equipment,consulting the results of monitoring electrical energy quality in same period of time,to compare and analysis,to identification and screen out error property,get relative data.Results In total 356 times errors which are influenced by electrical energy quality,the errors of electric power source are 159 times,the errors of control portion are 157 times,the errors of signal channel are 20 times.Electric pollution induce descend of electrical energy quality,especially to electric power source and control portion of medical equipment.Conclusions Electric pollution make descend of electrical energy quality,induce increase of medical equipment error rate,lead safety traffic of medical equipment to bad side,technology department of medical engineering should on their high guard.
