Aloka SSD-260型B超仪在国内中小医疗单位拥有量不少,其操纵板面的开关,属轻触式机械按键开关,使用一段时间后极易失灵,特别是使用频度高的开关,如冻结开关。一但失效,其更换件不但价格昂贵,且难以找到;有关杂志以往介绍的修理方法,也不适于该型开关。本人经过摸索。发现一种简捷修复方法,使用结果,灵敏如新。此法不用打开仪器盖,没有专门知识的人也能修理。
Aloka SSD-260 type B ultrasonic apparatus has a lot of possession in domestic small and medium-sized medical units. The switch on the control panel surface is a touch-type mechanical key switch. After a period of time, it is easy to malfunction, especially when the frequency of use is high. Such as freezing switch. Once it fails, the replacement parts are not only expensive, but also difficult to find; the repair methods previously described by the magazine are not suitable for this type of switch. I explored. A quick fix was found. The results were as sensitive as new. This method does not require opening the lid of the instrument, and people who do not have special knowledge can repair it.
