Anlysis and Research of Internal Impedance Modeling of Noise Source Based on Colorectal Endoscope
【摘要】 针对医用大肠内窥镜的电磁干扰问题,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,研究电磁干扰处理方法,提出了针对医用大肠内窥镜传导电磁干扰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医用大肠内窥镜的传导高频噪声,达到GB 9254标准要求.
【Abstract】 According to the medical prostate instrument electromagnetic interference problems,the paper analyzes common mode and differential mode noise mathematical model,studies the electromagnetic interference processing method,and proposes the solution of medical instrument prostate conducted electromagnetic interference noise. The experimental results show that the proposed method can effectively suppress the high frequency noise conduction medical prostate the instrument,thus reaching the requirements of GB 9254.
