Study on the Quantitative System for Acupuncture Manipulations Based on Electromagnetic Induction

Abstract

In order to solve the problems of the complicated structure and the short life of quantitative systems for acupuncture manipulations, a new quantitative method based on electromagnetic induction was proposed in this paper. In this method, the exciting coil and the induction coil were sensing elements, and the time domain parameters of the induced voltage were quantitative indicators. It can perform the lifting-inserting deepness, the entwisting frequency and manipulation time accurately. The feasibility of this method was verified by simulation, and the quantitative system was designed. In this paper, the lifting-thrusting and entwisting manipulations were chosen to do controlled experiment between experts and novices. Statistical methods are used to analyze the voltage variance in time domain. The experimental results show that coefficients of dispersion of experts are lesser than those of novices and the time of voltage rise, voltage fall and total manipulation time are lower than those of novices. The research results show that this method can accurately quantize the acupuncture manipulations. It will provide a scientific and normative standard for the acupuncture manipulations.
