The principle of sphygmomanometer:
The principle of measuring blood pressure by bracelet can be divided into three kinds, namely photoelectric method, ECG method and oscillometric method. At present, the popular blood pressure bracelet usually adopts photoelectric method, which is portable and easy to use compared with traditional mercury sphygmomanometer and electronic sphygmomanometer.
Generally, the bracelet collects the pulse wave waveform of the wrist through the photoelectric sensor, analyzes the characteristic parameters such as the rising slope of the pulse wave and the band time, obtains the specific calculation formula, and estimates the blood pressure value.
This estimate is not accurate, so it is recommended to use a professional sphygmomanometer to measure blood pressure. For several common blood pressure bracelets, it is impossible to prepare for the measurement of 100 with the current technology, so the measured value of the bracelet can be used as a reference, but you can't believe it all.
