γ免疫计数器的构造原理及常见故障分析

Structure and function of γ-immunoassay counter and its troubleshooting

γ免疫计数器目前已经在各级医院得到广泛的使用,通过介绍该设备的基本原理及常见故障的排除方法,更有效地维护好和使用好该设备。以中佳光电公司GC-1200双探头仪器为例,从探测器、电子电路、机械传动系统、计算机等部分来阐述原理。在医疗设备维修中要了解、掌握机器的原理,不可盲目动手以免导致机器故障的扩大化。

The γ-immunoassay counter is now widely used in hospitals of different levels.In order to help improve the maintenance of this equipment,this paper discussed its structure and function,and gives some troubleshooting tips for it.Using the GC-1200 double-detector counter produced by Zhongjia Photoelectricals Co.as example,this paper discussed the principles of γ-immunoassay counters in terms of the detector,the electronic circuit,the mechanical transmission system,and the computer.Based on the discussion above,the principles for the counter were clarified,and troubleshooting tips for common problems in using the counter were presented.In the maintenance of medical equipment,one has to have a good understanding of the principles involved in order to repair the equipment in a timely fashion.Repair efforts unguided by such understanding may lead to the worsening of the problem.
