Since ancient times, Chinese medicine has been diagnosing and treating diseases based on the four diagnoses and the eight principles handed down from generation to generation. It is also based on the four diagnostic methods (look, smell, ask, and cut) to identify the symptoms of the eight syndromes (Yin, Yang, superficial, internal, cold, heat, deficiency, and actual) to make diagnosis and treatment. The “cut” of the four diagnoses is the key to diagnosis, including pulse cutting and body pressure examination, pulse cutting is to press the three parts of the hands inch, guan and shaku to match the five organs, according to the shape of the radial artery pulsation, to measure the pathology of the organs and internal organs is Yin, Yang, table, lane, cold, heat, deficiency, and real. Torso pressure points are used to identify which meridian and which part of the body the lesion is located. Certain acupuncture points can also reflect the pathology of the internal organs. In terms of pulse cutting, there are many subjective components, and it is unlikely that all internal organs and meridian pathologies can be detected from the pulse, nor is it possible to detect all internal diseases by pressure diagnosis of meridian points. For a long time, we all hope to have an objective instrument to show the whole body pathology. The author has been using the “20 Meridians Automatic Measuring Instrument” in clinical practice for more than 20 years as an objective reference for the identification of the internal organs and meridians of the whole body based on the measured data. Through repeated validation, it is believed that it can be used as an objective indicator for clinical diagnosis in Chinese medicine and acupuncture, and the analysis of the indicator can suggest the eight levels of identification of the internal organs and meridians, and can correctly locate the lesions of internal organs, meridians, spine and joints, which greatly improves the diagnosis and treatment effect. The original meridian electrometer was to determine the twelve meridians of the hands and feet plus the Eight Yu meridians (of the pancreas) and the Diaphragm meridian discovered by Dr. Yoshio Nagahama in Japan. After years of exploration, the authors discovered six new meridians (Fengmen, Da Loom, Du Yu, Qihai, Guan Yuan, and Middle Brawn meridians). Therefore, every finger and toe is covered with meridians, and the twenty meridians of the hands and feet correspond to the first vertebrae to the twenty vertebrae and the twenty dorsal yu, and the data measured by the forty well points on the left and right of the hands and feet can basically provide the normal or abnormal conditions of the internal organs and meridians of the whole body, and the dialectic and treatment of the presence of the meridian segments in combination with the eight syllables and the relationship between the meridians, the thoracic, lumbar and sacral vertebrae and the meridians can obtain ideal results. This measuring instrument consists of measuring part, automatic diagnosis part and control keyboard. The measuring part consists of a probe connected to the monitor through the measuring line; the diagnostic part consists of a single microcomputer system that receives the input data of the twenty meridians and converts the analog data into digital data through an analog/digital converter for storage after processing by the central processor; the automatic diagnostic book of the twenty meridians data can be printed through the operation function keys. The instrument combines the electric measurement data of the twenty meridians with the theory of identification in Chinese medicine, which can objectively and correctly indicate the diseased internal organs, meridian parts and the deficiency of yin and yang, the instrument is simple to use and has high diagnostic specificity, which is applicable to Chinese medicine and acupuncture diagnosis and treatment. The eight principles of identification (yin and yang, surface and interior, cold and heat, deficiency and reality) take yin and yang as the general principle. How to distinguish yin and yang to select acupuncture points for acupuncture treatment is an existential problem. In general, acupuncture books and clinical treatment of diseases of the internal organs always take points bilaterally. For example, in the case of gastrointestinal diseases, the main points are always taken bilaterally, such as Neiguan and Sanli; in the case of liver and gall bladder diseases, the main points are always taken bilaterally, such as Yanglingquan and Taichong. But each internal organ has yin and yang qi and blood, customarily for the lung, there is lung yin, lung qi, for the stomach, there is stomach yin, stomach qi, for the heart, there is heart yin, heart blood, heart yang, heart qi, for the liver, and liver yin, liver blood, liver qi, liver yang, for the kidney, and kidney yin, kidney yang, kidney qi, etc. If the stomach is deficient in yin, the stomach is also deficient in qi, the stomach is also supplementing the feet on both sides of the three li. Another example is that heart blood stagnation diarrhea bilateral Shen Men, and heart fire exuberance also diarrhea bilateral Shen Men, does this become yin and yang indistinguishable? How can this be resolved? The data measured over the years, combined with the symptoms, pulse, and tongue, show that most cases of Yin deficiency, Blood deficiency, and dryness of fluids have low Heart, Liver, and Kidney meridians, while cases of Yang deficiency, Qi deficiency, and Middle Qi subsidence have low Lung, Heart, Spleen, and Kidney right sides. In cases of phlegm, water-dampness and stagnation, the left side is high, and in cases of external evil, dryness and fire, hyperactivity and stagnation of qi, the right side is high. As for phlegm and fire, phlegm-heat, damp-heat, and qi stagnation and blood stasis, they are high on both sides. Therefore, the authors believe that acupuncture should be used for treating internal organs, with yin and yang deficiency and blood deficiency on the left side, and yang and qi deficiency on the right side. For Yin deficiency (including water, dampness, phlegm and stasis), diarrhea on the left side is appropriate. For Yang deficiency (including fire, heat, hyperactivity of Yang and stagnation of Qi), diarrhea on the right side is appropriate. Based on the measured data combined with the analysis of symptoms, a diagnosis is made, and acupuncture points are taken to supplement and treat the disease. Meridian disease: Mainly symptoms that occur when the twenty meridians travel through areas (including joints, ligaments, muscles, tendons, blood vessels, etc.) and related organs are diseased. If the data measured by the meridians are abnormal, those who are low are deficient and should be tonified; those who are high are real and should be diarrhea. I. Hand meridians 1.

Forehead pain is at the Zanzhu point. Meridian diseases are various diseases and pains including meridians, ligaments, tendons, and skin. The abnormality of their measurement data is an indication of deficiency and actuality of the meridians; deficiency means empty and insufficient, which is the weakness of the meridians themselves and needs to be tonified; actuality means excessive and surplus, which is the invasion of external evil into the meridians, causing blockage and obstruction and needs to be eased. After adjustment, the median is too low for deficiency and should be lightly stimulated to support the righteousness; too high for actuality and should be strongly stimulated to remove the evil. In a small number of patients, the lesions that fail to manifest at the beginning of the measurement can manifest after 1-2 treatments, and in a very small number of patients, they never manifest, so please identify the deficiency and reality as described above. It is believed that the key to the efficacy of acupuncture lies in the correct identification of the evidence (identification of the meridians, identification of the internal organs, identification of the eight principles). How can correct identification be achieved, the first step should be to combine the new meridians with the old meridians as the basis for identification. Because there are many diseases involving the new meridians, the old meridians alone do not seem to be comprehensive enough. Secondly, it is how to be able to correctly and objectively discriminate the eight meridians. At present, it seems that the electrical determination of the meridians can be used as an objective indicator for the differentiation of evidence, which can objectively show the disease meridians (organs, internal organs and meridians) and the deficiency (positive deficiency) and the actual (evil actual). Targeted use of acupuncture to support the positive and diarrhea the evil can quickly achieve adjustment and balance. Of course, the meridian electrometer should be continuously improved with modern science to make it more advanced, computerized and scientific. In this way, the effectiveness of acupuncture and moxibustion can be continuously improved to better serve the people of the world.
