When a person is sick or in the early stage of illnesses, low resistance and other abnormal appearances can be found on the auricular points that have corresponding relationships with the diseased organs. Now most auricular point detection instruments have many disadvantages, such as single detection function and lacking of quantitative auricular point resistance measurement, statistic analysis and visual display of equal resistance range using pseudo-color image. Moreover, most current detection instruments can not carry out statistic analysis of auricular point resistance in the anatomic and neural subareas. We designed a new type of auricular point detection system. The new system implements three different functions for measuring the resistance quantitatively, calculating and analyzing the resistance values in the anatomic and neural subareas statistically. In addition, it can display the auricular points with equal resistance range using pseudo-color image. The new system provides quantitative and visualized results for clinical detection.
