Blood pressure measurement methods in medical diagnosis include direct measurement and indirect measurement, and noninvasive indirect measurement is often used in clinical and home measurements; indirect measurement is classified into korotkoff sound method, oscillometric method, and the like. The Korotkoff sound method needs human hearing to measure the blood pressure, is easily influenced by external environment and human subjectivity, and the mercury sphygmomanometer on the market measures by utilizing the Korotkoff sound method; the oscillography is a commonly used blood pressure measuring method of an electronic sphygmomanometer and has the advantages of strong anti-interference performance, real-time monitoring realization and good repeatability. The oscillometric method is classified into inflation-based measurement and deflation-based measurement. The oscillography principle based on inflation measurement is as follows: in the process of inflating the cuff, the pressure sensed by the pressure sensor is continuously increased, and at the moment, a mixed wave of static pressure and pulse wave oscillation waves can be detected from data collected by the pressure sensor, wherein the pulse wave oscillation waves come from the vibration of a blood vessel wall; when the static pressure of the cuff is smaller than the diastolic pressure of a human body, the blood vessel wall of the artery is fully expanded in the period, the elastic range of the blood vessel wall is small at the moment, and therefore the amplitude range of the oscillation wave is also small; when the static pressure of the cuff is increased to the average pressure, the arterial wall is in a load-free state, and the oscillation wave reaches the maximum amplitude value; when the static pressure of the cuff is increased to be larger than the systolic pressure, the artery wall is compressed and the elastic oscillation wave appears due to the impact of the near-end pulse; and estimating a blood pressure value according to the relationship between the collected cuff static pressure and the separated pulse wave amplitude. The oscillometric rule based on the deflation measurement is to extract the pulse wave variation during the deflation of the cuff, as opposed to the procedure based on the inflation measurement.
