B 型超声诊断仪(B 超)是一种结构复杂、价值较高的医用精密电子仪器。由于生产厂家不提供电路,检修工作比较困难。因此,探求在无电路图的情况下,其检修方法有实际意义。笔者经过长期摸索实践找到了一些方法,成功率较高。现将直观检查技巧介绍给大家,供参考应用。1.直观检查技巧直观检查就是运用视(观察)、触(手摸)、闻(耳听、鼻嗅)等手段直接诊断的方法。是最简单、最实用,行之有效的方法。
B-type ultrasound diagnostic apparatus (B-type) is a complex structure, high value of medical precision electronic equipment. As the manufacturer does not provide the circuit, maintenance work more difficult. Therefore, the search in the absence of the circuit case, the maintenance method is of practical significance. The author found some ways through long-term exploration practice, a higher success rate. Visual inspection techniques are now introduced to you for reference applications. 1. Intuitive examination techniques Intuitive examination is the use of visual (observation), touch (hand touch), smell (ear, nose smell) and other means of direct diagnosis. Is the easiest, most practical and effective way.
