Study Of Medical Device Failure Analysis And Maintenance Methods

The dissertation is concentrated on the systematic and comprehensive researches on troubleshooting analyses and maintaining means of medical instruments and equipment. These have been formulated, the necessity of the operation of sophisticated medical instruments and equipment under proper conditions and environments and the importance of sequencing of maintenance of medical instruments and equipment, and procedures and ways of maintenance of medical instruments and equipment So long as the instruments and equipment are operated under suitable conditions and environments, and maintained at regular intervals and according to strict maintaining regulations and rules given by manufactures, durable, stable and reliable operation of the instruments and equipment and successful development of tasks in all-level medical and hygiene units can be ensured, which will make good social and economic benefits.What's worrying us is the situation of the line of troubleshooting and maintaining of medical instruments and equipment, on the one hand, at present, more than 90% domestic market of high-end medical instruments and equipment has been occupied by several international manufacturers and sale companies, who are trying to make a monopoly of the after-sale service market of the instruments and equipment by means of power-on cypher and frequently changing the cyphers of maintaining programs and locking technical matericals and schematics. On the other hand, in our country, there are few professionals in the line in hospitals and other hygienic units at county-level and under the level. Although there are some professionals in the line in hospitals and other hygienic units at district-level and province-level, they have few opportunities for their advanced studying and training. It is difficult for them to keep up with the developing speed of medical instruments and equipment by the knowledge they previously studied, Thus it is urgent for government officers with regard to the line to pay highly attention to the situation, and to standardize the after-sale service market and to strengthen the professionals continuing education and training, and to increasingly chance their technical levels and to increase their responsibilities and working fervidities. These have also been stated systematically, different features, basic analysis methods and troubleshooting procedures for ultrasonic devices, chemistry analyzers, ECG and monitors and X-ray machine. In addition, the important uses of switching power supplies in medical equipment and the difference between switching power supplies and traditional ones, design methods and troubleshooting ways of switching power supplies have also been introduced. At last, the prospects and developing tendency in troubleshooting and maintaining of medical instruments and equipment have been discussed simply.
