PROBLEM TO BE SOLVED: To reliably discriminate the position of acupuncture point with a simple hardware constitution.SOLUTION: An electric current generated from a current generating part 1 is impressed on measurement points #1-#n on the skin 30 of a subject through current impression electrodes 31, 32-3n. A measurement part 6 measures the energized current and a voltage generated on the skin by energizing. A frequency analyzing part 7 performs frequency analysis on the measured current and voltage, so as to calculate a skin impedance Z(jf) at each measurement point. A feature quantity generating part 8 calculates the frequency characteristic K(f)=XZ(f)/RZ(f) being the ratio of a real number part RZ(f) to imaginary number part XZ(f) in the skin impedance Z(jf), based on the frequency characteristic of the skin impedance Z(jf) at the measurement points #1-#n. A discriminating part 9 discriminates the position of acupuncture point from the respective measurement points, based on a difference in the frequency characteristic K(f).COPYRIGHT: (C)2007,JPO&INPIT【課題】 簡単なハードウエア構成で、信頼性のある経穴の判定を行う。【解決手段】 電流発生部1から発生させた電流を、被検体の皮膚30の測定点#1~#nへ電流印加電極31、32~3nを通じて印加し、通電した電流と、通電によって皮膚に生じた電圧を測定部6にて測定し、周波数解析部7にて測定された電流と電圧の周波数解析を行い、各測定点での皮膚インピーダンスZ(jf)を算出し、特徴量生成部8にて測定点#1~#nでの皮膚インピーダンスZ(jf)の周波数特性から、皮膚インピーダンスZ(jf)の実数部RZ(f)とXZ(f)虚数部の比の周波数特性K(f)=XZ(f)/RZ(f)を算出し、判定部9にてその周波数特性K(f)の違いに基づき各測定点のなかから経穴位置を判定する。【選択図】 図1
