摘要
本研究针对现行医药行业标准YY/T 0196-2005《一次性使用心电电极》中交流阻抗检测方法的频率覆盖不足问题,通过定制的低频阻抗谱测试工装,选取6个厂家的一次性心电电极在(0.05~100)Hz频带下的交流阻抗特性进行实验研究。实验结果表明,容抗分量对阻抗模值的贡献随频率升高显著下降,且不同频率下的阻抗模值呈现频率依赖性变化。研究为心电电极性能评价提供了多频率、复阻抗维度的数据支撑,为后期的标准修订提供参考。
This study addresses the issue of inadequate frequency coverage in the AC impedance testing method specified in the current medical industry standard YY/T 0196-2005 Disposable ECG Electrodes.Using a customized low-frequency impedance spectrum testing fixture,experimental research was conducted on the AC impedance characteristics of disposable ECG electrodes from six manufacturers across a frequency band of(0.05~100)Hz.The results show that the contribution of the capacitive reactance component to the impedance magnitude decreases significantly with increasing frequency,and the impedance magnitude at different frequencies exhibits frequency-dependent changes.This study provides multi-frequency and complex impedance dimensional data support for the performance evaluation of ECG electrodes and offers a reference for future standard revision.
