秒级微动人体经穴阻抗计量检测仪的研制

A secs-level detector for human meridian impedance

为有效分析人体经穴生物阻抗的波动特性，进而实施经穴疾病关联诊断与中医干预，本小组研制了秒级微动人体经穴阻抗计量检测仪，该仪器最小测试间隔为0．01s，可以0．24s的周期循环跟踪人体24处经穴阻抗微动情况，具有高效无创、操作方便、实时性好等优点．实测数据表明，仪器重复性相对误差〈0．067％，仪器准确度测量的相对误差为0．22％～0．75％，目前同类仪器的相对误差水平为〈0．1％和1％，因此秒级微动人体经穴阻抗计量检测仪可以满足实用要求．

With the aim to analysis effectively the volatility of the human meridian impedance, as for the diagnosis of meridian diseases and the traditional Chinese medical intervention, a sees-level detector of human meridian impedance is developed. The minimum test interval of the detector is 0. 01 second and it can track and test meridian impedances at 24-points in a period of 0. 24 second. The developed detector is non-invasive and with high efficiency, it is also easy to use and good in a real time test. Experimental data shows that the relative error of repeatability of the detector is lower than 0. 067% and the relative error of accuracy lies between 0.22% and 0. 75%, while for the existing similar detectors in use, the corresponding values are respectively lower than 0. 1% and 1% ; hence the developed detector can meet the practical requirements very well.
