20090036798 | ACUPUNCTURE POINT POSITION EVALUATING APPARATUS - A technology for determining an acupuncture point with the reliability with the use of a simple hardware configuration in an acupuncture point position evaluating apparatus is disclosed. According to the technology, a current generated in a current generating section is applied to measurement points of skin of a subject through current application electrodes. The applied current and a voltage generated in the skin by the current application are measured in a measuring section. In a frequency analyzing section, the measured current and the measured voltage are provided with frequency analysis, and skin impedance Z(jf) in the respective measurement points is calculated. In a characteristics amount generating section, based on the frequency response of the skin impedance Z(jf) in the measurement points, frequency response K(f)=XZ(f)/RZ(f) as a ratio between real part RZ(f) and imaginary part XZ(f) of the skin impedance Z(jf) are calculated. In a determining section, based on the difference of the frequency response K(f), an acupuncture point position is determined from among the respective measurement points. | 02-05-2009 |
