摘要
现代医疗器械更偏向于高精确度、高敏感度和小型化,其所处的电磁环境越来越复杂.外界电磁干扰对医疗设备会产生影响,严重时甚至影响医生的诊断.本文结合心音心电检测仪,基于医疗器械测试标准对传导发射测试、辐射发射测试和静电放电这3个测试项目进行了研究,提出了壳体整改,增加滤波电路、磁环、电荷释放电路等整改方法.对其他类型相关医疗器械的电磁兼容问题分析和整改,有一定的参考借鉴作用.
Abstract
Modern medical devices are more inclined to high precision,high sensitivity,and miniaturization,resulting in more and more complex electromagnetic environments.External electromagnetic interference will also affect medical devices,and even affect doctors'diagnosis in severe cases.In this paper,combined with the heart sound electrocardiograph detector,the conduction emission test,radiation emission test and electrostatic discharge test are studied based on the medical device test standard.Some rectification methods are proposed,such as rectifying the shell,adding the filter circuit,adding the magnetic ring and adding the charge release circuit.It can be used as a reference for the analysis and rectification of other types of related medical devices.
