Description

Physiological signal measuring device

A measuring device, especially a physiological signal measuring device for measuring physiological signals.

Traditional Chinese medicine uses the four diagnostic methods of "seeing, smelling, inquiring, and cutting" as the method of diagnosing diseases. Among them, pulse consultation has been used for at least two thousand years since ancient times. It is useful for identifying diseases, judging conditions, and distinguishing pathogenesis. It is of great significance and is an indispensable step in TCM treatment. However, due to the extremely varied pulse conditions and extremely small signals, the famous Jin Dynasty doctor Wang Shuhe said: "It is easy to understand, but it is difficult to understand." Without years of training, it is difficult to correctly diagnose and treat. Due to the characteristics of pulse diagnosis, and the diagnosis is often limited by the physician's subjective and experience inheritance, Chinese medicine cannot be widely studied, used, or even researched and developed.
