DL-C-B型超短波治疗机故障分析与维修一例

摘要

Objective Ultrashort wave therapy apparatus has been widely used in clinical as an adjuvant therapy. It is necessary for medical equipment maintenance engineers to be familiar with the ultrashort wave therapy apparatus's working principle and maintenance of common faults to ensure it's normal operation. Methods According to the troubleshooting course of a special short circuit fault case of ultrashort wave therapy apparatus fault, we analyzed and narrowed the fault range via combining with fault phenomenon, working principle, circuit principle and the actual circuit. At last, the fault hidden trouble was detected by component test. Results After changing the performance of the components, the ultrashort wave therapy apparatus ran normally. Conclusion This method is feasible and the maintenance cost is low. This research can offer reference for the maintenance of ultrashort wave therapy apparatus, as well as provide maintenance direction for medical equipment maintenance engineers.%目的 超短波治疗机作为辅助治疗方法已被广泛应用于临床,为保障其正常工作,熟悉其工作原理和常见故障的维修对医疗设备维修工程师来说是有必要的.方法 本文通过分析检修DL-C-B型超短波治疗机一例特殊短路故障,结合故障现象、超短波的工作原理、电路原理和实际线路,通过分析缩小故障范围,逐个元器件测试发现故障隐患.结果 经过更换性能变差的元器件,超短波治疗机运行正常.结论 针对此类故障现象,该维修方法可行,且能维修成本低,为超短波治疗机维修提供借鉴经验.同时,为初学医疗设备维修工程师提供维修方向.
