摘要
针对医用大肠内窥镜的EMI(Electromagnetic interference,EMI)电磁干扰问题,分析插入损耗法噪声源内阻抗建模和电流探头法内阻抗建模,研究了EMI处理方法,提出了针对医用大肠内窥镜传导EMI噪声问题的解决方法。试验结果表明,所提方法可以有效抑制了医用大肠内窥镜的传导高频噪声,达到GB9254标准要求。
According to the medical prostate instrument(Electromagnetic EMI prostate interference,EMI)electromagneticinterference problems,analysis of common mode and differential mode noise noise mathematicalmodel,study the EMI processing method,proposes the solution of medical instrument prostate conductedEMI noise.The experimental results show that the proposed method can effectively suppress the high frequencynoise conduction medical prostate the instrument,reached the requirements of GB9254.
