Description
Technical Field
The invention relates to clinical detection equipment of traditional Chinese medicine, in particular to a handheld acupoint impedance detector.
Background
The biological impedance (electrical bio-impedance) technology is a non-invasive detection technology for extracting biomedical information related to physiological and pathological conditions of human body by using electrical characteristics and changes of biological tissues and organs, and is generally characterized in that a tiny measuring current or voltage is sent to a detection object by means of electrodes arranged on the body surface to detect corresponding electrical impedance and changes of the electrical impedance, and then related physiological and pathological information is obtained according to different application purposes. The technique has the characteristics of no wound, low cost, safety, no toxicity or harm, simple operation, rich information and the like, and is easy to be accepted by doctors and patients.
Acupoints, known as "Yu" points, refer to specific points on the skin surface of the human body, i.e., points on the skin surface, and are generally classified into four types, i.e., jing Xue Ji, azhi and Xue. Most acupoints are located on the meridian line. The traditional Chinese medicine can treat diseases by stimulating corresponding meridian points through acupuncture or massage, pressing and moxibustion. Acupoints are proper nouns in Chinese culture and traditional Chinese medicine, and are mostly nerve endings and places with more blood vessels.
It has been studied that the bioimpedance value of acupoints is lower than that of non-acupoints. When a human body is ill, the biological impedance value of the corresponding acupoint changes, so that the health condition of the human body can be mastered very simply, conveniently and intuitively by monitoring the change trend of the biological impedance value of the acupoint. However, no instrument is currently available that can measure the bio-impedance value of an acupoint.
The theory of traditional Chinese medicine is formed in the period of war between spring and autumn, and the application has been carried out for more than two thousand years. However, since western medicine entered china, people began to question traditional Chinese medicine in the mode of thinking of the western medical system, even putting traditional Chinese medicine into debate between existence and disuse. One of the root causes is that the diagnosis result and effectiveness of traditional Chinese medicine are largely dependent on subjective judgment of doctors. How to make the diagnostic index of traditional Chinese medicine more objective and have diagnostic reference value is a break-through for the development of modern traditional Chinese medicine.
