摘要
目的通过探寻电针治疗仪临床使用中存在的问题,为电针治疗仪国家标准的建立奠定基础。方法对临床文献中电针治疗仪型号、刺激波形及复合波形特征、刺激频率、电流强度、脉冲宽度的报道情况进行分析。采用RM6240C多道生理信号采集处理系统,对3种电针治疗仪的实际输出频率进行测定,观察电针治疗仪实际输出参数的精确性,总结电针治疗仪存在的问题。结果电针治疗仪使用参数报道情况显示,在统计的5项指标中波形（96.2%）被描述的概率最高,其次为电针治疗仪型号（88.8%）、频率（61.7%）、电流强度（11.2%）,被描述概率最低的为脉冲宽度（1.8%）。临床最常用的电针治疗仪为G6805系列,但其生产厂家众多,亚类混乱。波形被描述的概率较高,但对复合波形特征的描述较少。临床选用电针使用频率差异较大,从0.8~400 Hz均有描述,但描述欠精确,大多数文献以范围表示输出频率。3种电针治疗仪的输出挡位与电针治疗仪频率的实际输出不对应,且实际频率输出范围与说明书中标注的频率可调范围差异较大。结论电针治疗仪存在缺少参数实际输出值的显示装置、旋钮式调节控件调节参数不够精确、频率的实际输出值达不到说明书中的额定范围等问题。
Objective To lay foundation for the establishment of national standards of electroacupuncture devices by exploring the problems existing in their clinical application. Methods An analysis was made of the models, stimulus waveforms and complex waveform characteristics, stimulus frequencies, current intensities and pulse widths of electroacupuncture devices reported in clinical literature. The actual output frequencies of three kinds of electroacupuncture devices were measured using RM6240 C multi-channel physiological signal acquisition and processing system to observe the accuracy of their actual output parameters and summarize the problems existing in electroacupuncture devices. Results The reports on electroacupuncture device parameters showed that of the five indicators analyzed statistically, the frequency of described waveforms was the highest（96.2%）; the frequencies of described models（88.8%）, stimulus frequencies（61.7） and current intensities（11.2%） were next; the frequency of described pulse widths was the lowest（1.8%）. The electroacupuncture device most commonly used clinically was G6805 series, but the subtypes were confused because of many manufacturers. The waveform was described more frequently but complex waveform characteristics were less. The difference of frequencies of clinical application of electroacupuncture was larger. They were from 0.8-400 Hz but described less accurately. The output frequency was indicated by the range in most of the literature. The output adjusters of the three kinds of electroacupuncture devices did not correspond to their actual output frequencies. There was a larger difference between the actual range of output frequencies and the adjustable frequency range indicated in the instruction. Conclusions Electroacupuncture devices have the problems of lacking a display unit of actual output parameter values, the adjusting parameters of the knob adjustable controller being not precise enough and the actual values of output frequencies not reaching the rated range in the instruction.
