GE-Lunar DPX-MD+骨密度仪故障维修3例
|
摘要
双能X线骨密度仪是检测人体骨密度、骨量以及z值等生理数据的大型医疗设备,本院的GE-Lunar DPX-MD+骨密度仪是在双能X线骨密度仪中广泛使用的常规装备。本文简单介绍了该型号骨密度仪的关键组成部分和基本原理,强调了设备使用、维护维修中应该注意的细节,重点介绍了该型骨密度仪球管故障、探测器故障、电机故障的现象,通过对规章现象的分析判断,排除干扰因素,确定故障部位并完成检修。
Dual-energy X-ray absorptiometry is a kind of large medical equipment which can be used to test human bone mineral density, bone mass, z value and other physiological data. GE-Lunar DPX-MD+ Bone Densitometer in our hospital is a widely used conventional equipment of dual-use X-ray absorptiometry. The key components and basic principles of this bone densitometer was briefly introduced. The details which should be paid attention to during the process of using and maintenance was emphasized. The faults phenomenon of tube failure, detector failure and motor failure were emphatically introduced. Through analysis of the rules and regulations, the interference factors were excluded, the fault locations were identified and the machine was maintained.
