Description

A wearable wireless pulse diagnosis instrument system based on pulse spectrum analysis

technical field

The utility model relates to health care equipment and modern traditional Chinese medicine pulse science, in particular to a wearable wireless pulse diagnosis instrument system based on pulse spectrum analysis. the

Background technique

The theory of modern Chinese medicine believes that the working process of the blood circulation system is a process of resonance, and different viscera have different vibration frequencies. From the viscera to the internal organs, the frequency of resonance gradually increases. There are 12 harmonics in total from the 12 meridians of the human body. Bladder Meridian, Large Intestine Meridian, Sanjiao Meridian, Small Intestine Meridian and Hand Shaoyin Heart Meridian. The pericardial meridian is defined as the 0th harmonic, which is the total composite wave, that is, the total output of the heart. When the heart beats, it actually outputs a pulse. In each heartbeat cycle, the real time for blood to be pumped from the ventricles to the aorta is about 0.1-0.2 seconds. Carefully analyze this pulse, it contains the frequency of each meridian, that is, the harmonics of each viscera, but the specific gravity is different and the higher the frequency, the smaller the energy, and the diagnosis is made according to the difference in energy. This is the basis for us to perform frequency spectrum analysis on the pulse, and it is also the theoretical basis for our design of this project. the

Spectrum Analysis (Spectrum Analysis) is a process of expanding the signal strength sent by the signal source in order of frequency, making it a function of frequency and examining the law of change. By analyzing the frequency spectrum of the collected pulse signal, we can get the required harmonics, and then the single-chip microcomputer analyzes and processes the harmonic signals. the

At present, many instruments for pulse diagnosis have appeared at home and abroad, but most of them are either bulky, expensive, complicated to operate, or have few indicators for testing. A low-cost, easy-to-operate, lightweight and convenient pulse diagnosis device with wireless transmission is often urgently needed by modern people who pursue health. the
