Description

technical field [0001] The invention belongs to the technical field of electronic equipment, and in particular relates to a pulse signal extraction device for pulse diagnosis of traditional Chinese medicine. Background technique [0002] With the rapid development of today's society, people's life and work pace are very fast, which makes people's life more and more stressful, and the body is easy to enter sub-health or disease state. In terms of health preservation, traditional Chinese medicine has many effective methods for the body in a sub-healthy state. Traditional Chinese medicine has a long history and is unique in the world. Pulse diagnosis is an important link in the "four diagnostics" of traditional Chinese medicine: looking, smelling, asking, and feeling. It is one of the essences of Chinese medicine and a manifestation of the basic principle of TCM diagnosis. Traditional Chinese medicine believes that when qi and blood in the viscera of the human body become dis...
