随着现代科学技术的发展,推动了临床医学的医疗水平。目前许多医疗电气设备中都采用了先进的电子信息工程技术,但是这些设备的抗干扰性对于其正常使用有重要影响,且设备对外界造成的辐射也会影响周围设备的使用情况。因此医用B型超声诊断仪器(简称:B超)同其它医疗电气设备一样,其电磁兼容设计显得非常重要。医疗场所的电磁环境需要重视。文章主要针对医用B超仪器电磁兼容设计展开讨论。
With the development of modern science and technology, the medical level of clinical medicine has been promoted. At present, many medical electrical equipment adopts advanced electronic information engineering technology, but the anti-interference of these equipments has an important influence on their normal use, and the radiation caused by the equipment to the outside world will also affect the use of surrounding equipment. Therefore, medical B-type ultrasound diagnostic apparatus (referred to as: B-ultrasound) with other medical electrical equipment, its EMC design is very important. The electromagnetic environment of medical places needs attention. The article mainly discusses the electromagnetic compatibility design of medical B-ultrasonic instruments.
