Problems solved by technology

However, the disadvantage of this method of collecting pulse waves is that it is necessary to repeatedly adjust the position of the sensor in order to find the position on the wrist where the pulse beats stronger
In actual operation, it often happens that it is difficult to find a suitable position due to the influence of the blood vessel position and the thickness of human tissue of the subject. In this way, it will inevitably cause interference to the measured signal, which is quite inconvenient to use, and the measurement results are often inconsistent. imprecise
Moreover, in the above-mentioned measurement method, tracing the pulse waveform and measuring blood pressure need to be carried out separately, which increases the complexity of the operation
Moreover, since the characteristics of the human body such as blood pressure change with time and the environment, separate measurement will easily cause additional measurement errors due to the passage of time and changes in the environment

Embodiment Construction

[0024] Various monitors and electronic sphygmomanometers on the market widely use the oscillometric method to measure blood pressure non-invasively. Oscillometric blood pressure measurements can be taken on the upper arm or wrist. When using the oscillometric method to measure blood pressure, inflate the cuff or wristband so that the air pressure exceeds the systolic blood pressure of the subject. When the air bag is gradually deflated, the vibration of the human artery wall causes the pressure of the cuff or wristband to oscillate. Pressure oscillations on the cuff or wristband are recorded. Fitting the amplitude of the shock wave sequence in the process of pressure drop can obtain the envelope curve of the shock amplitude changing with the cuff or wrist pressure, and the shape of the envelope line is an important basis for determining the diastolic and systolic blood pressure. The corresponding pressure at its maximum point is the mean intraarterial pressure. The systolic ...
