摘要:
随着医疗器械行业电磁兼容标准YY0505-2012的发布实施,其电磁兼容问题迫切需要解决.针对复杂医疗电子设备产生的辐射EMI噪声,本文建立两种辐射噪声理论模型,即芯片晶振时钟信号引起的辐射噪声模型以及PCB板软线路板(FPC)引起的辐射噪声模型,并提出相应噪声抑制方法. 实验结果表明,采用文中方法,某型医疗微波治疗仪、医疗尿量监测仪能够通过医疗器械行业电磁兼容标准YY0505-2012标准测试,噪声抑制效果可达10 dBμV/m以上,从而验证了文中方法的有效性.
Abstract:
With the implementation of the YY0505-2012 standard of electromagnetic compatibility for medical devices industry,the issue of electromagnetic compatibility needs to be solved urgently. In order to analyze radiation EMI noise produced by complex medical electronic equipment,two theoretical models are proposed,including clock signal of chip crystal,flexible Printed Circuit(FPC)board. Furthermore,noise reduction methods are designed on the basis of the above radiated noised. The experiment results show that a microwave laser and urine monitor can pass the YY0505-2012 standard for medical devices industry by employing the suggested approaches of paper and that its noise decreased over 10 dBμV/m,so the validity of the approaches is verified.
