Abstract

In this letter, electromagnetic interference (EMI) in medical electronic systems related to the use of ready-made connecting devices is investigated. It has been observed that under some conditions, an inadequate number of shielding pins and their distribution in connectors and plugs may cause unacceptable EMI, especially when it occurs in, e.g., a surgery room. In real-life situations, installers are often deciding on how to arrange the shielding connections, while not being trained in electromagnetic compatibility-aware design. To get more insight and reveal the influence of some parameters of the shielding wiring, a lab measurement setup has been derived from a real environment, showing the impact of using imperfectly shielded connectors with different number and distributions of shielding wires. Suggestions for reducing the EMI of systems are proposed and can be applied to support installation practices and/or debugging in practical situations and various user environments.

医疗电子系统中现成连接装置内部布线对电磁干扰的影响

在这封信中，研究了与使用现成连接设备相关的医疗电子系统中的电磁干扰(EMI)。据观察，在某些条件下，屏蔽引脚数量不足及其在连接器和插头中的分布可能导致不可接受的电磁干扰，特别是在手术室等场所发生时。在现实生活中，安装人员经常在没有接受过电磁兼容性感知设计培训的情况下，决定如何安排屏蔽连接。为了更深入地了解和揭示一些参数对屏蔽接线的影响，在真实环境中建立了一个实验室测量装置，显示了使用不同数量和分布的屏蔽线的不完全屏蔽连接器对屏蔽接线的影响。提出了减少系统电磁干扰的建议，这些建议可用于支持实际情况和各种用户环境中的安装实践和/或调试。
