摘要
目的:研究医疗设备快速故障诊断方法,在无图纸条件下的医疗设备故障诊断中准确快速地找到故障点。方法:采用系统状态检测法,利用在线测试仪和数字示波器或测试工装建立板级的系统状态库;结合既往信号流图法的设备故障维修成功案例。结果:基于系统状态检测的医疗设备快速故障诊断方法,既可提高故障诊断的准确性,又可提高在无图纸条件下的医疗设备故障诊断效率;成功排除了层流风机变频器、PM9000监护仪血氧板等设备故障。结论:基于系统状态检测的医疗设备快速故障诊断方法是对提高医疗设备维修效率的有效模式。
Objective:To explore a fast diagnosis method for fault of medical equipment so as to accurately and quicklyfast find fault point in the diagnosis for fault of medical equipment under the condition without any schematic diagram.Methods:The detection method of system state was adopted,and online tester and digital oscilloscope or the system situation database were applied in the method.Besides,the combination of successful cases database or classic signal flow diagram could increase both of accuracy and efficiency for fault diagnosis.Results:In the diagnosis without blueprint for fault of medical equipment,the detection that based on system state successfully eliminated the faults of frequency converter of laminar flow draught fan and blood oxygen board of PM9000monitor.Conclusion:The fast diagnosis method for fault of medical equipment that based on the detection of system state can provide helpful exploration for maintenance of medical equipment.
