To clarify some questions relative to fixed position of tsun-guan-chi in pulse diagnosis of Chinese medicine, we adopted the mode of researching both classical literatures and modern studies, and integrated a practical measurement into the study for further analyze and searches. First, we made a through inquiry of the theory in why the physicians take the pulse mostly in tsun-kou area. Second, we investigated into the developing of the denomination of tsun-guan-chi、the fixed position of operating categories both in quality and quantity, and considered the hemodynamic principles, thus we objectively analyze all advantages and disadvantages of every methods from the view of clinical practice and academic study. According to the result, we suggested that the tsun-guan-chi quantitification should be the standardized measurement operating protocol in fixed position of pulse diagnosis in tsun-kou area. The result will be contributive to the development of standardization of education and study in clinical pulse diagnosis, and also could be the foundation of the following clinical measurement study and sphygmograph development in the future.
