Research on Mathematical Distribution of Failure Time and Engineering Evaluation for Medical Electrical Equipment Based on Operation and Maintenance Data / 中国医疗器械杂志

This study mainly discusses the contents, methods and characteristics of the collection of operation and maintenance data, as well as the establishment and evaluation methods of the distribution model of the failure time of medical electrical equipment. The distribution models of failure time at three levels of medical electrical equipment are established by linear regression method and goodness of fit test:The first is the device level MTBF distribution model, the second is the failure rate distribution model of the failure mode of key components, the third is the calculation model of the influence coefficient of influence factor on the failure mode of key components. This study presents a method of establishing MTBF segment model and implements a calculation model of influence coefficient varying with time.

Research on the establishment and evaluation of the standardizing preventive maintenance template of medical equipment / 中国医学装备

Objective:In view of the different kind of equipment to develop proprietary standardization of medical equipment preventive maintenance template, and make a quantitative evaluation of effects.Methods: Set up the experimental group and control group, compare maintenance data and parameters of the quality control.Results: According to the standardization of the preventive maintenance of patient monitor template, maintenance data improved, quality indicators improved significantly.Conclusion: The establishment of the standardization of medical equipment preventive maintenance template, can improve the rate of running machines, security equipment in the best state operation, reduce the equipment failure risk, ensure the safety of the use of the equipment.
