Specifically, an electrocardiosignal sensor 3 and a photoelectric sensing module 4 are used for synchronously acquiring an electrocardiosignal and a pulse wave signal; because the cardiac signal comes from the contraction of the ventricle, and the peak value of the Pulse wave signal is caused by the contraction of the artery, on the same Time axis, the peak value on the cardiac signal waveform diagram and the Pulse wave signal waveform diagram appears with the delay of the signal, namely, the Pulse Transit Time (PTT) can be defined as the Time when the Pulse wave propagates from one position to another position, which reflects the transmission Time when the blood arrives at the measurement part of the photoelectric sensing module after being sent out from the heart, and the variation of the blood pressure is in direct proportion to the variation of the Pulse wave Transit Time (PTT), namely, the blood pressure and the Pulse wave Transit Time (PTT) are in a linear relationship. Therefore, the pulse wave conduction time PTT is combined by the electrocardio signals and the pulse wave signals, and the systolic pressure SBP, the diastolic pressure DBP and the pulse wave of the human pulse are passedThe blood pressure information of the human body can be obtained through the linear relation of the PPT. Exemplarily, the linear relation between the systolic pressure SBP and the pulse wave transit time PPT is strong, the accuracy of linear fitting is high, and the linear fitting formula between the systolic pressure SBP and the pulse wave transit time PPT is as follows:
wherein, a1、a0The contraction pressure SBP can be calculated for a first-order term coefficient and a constant term coefficient which are linear formulas respectively. The diastolic pressure DBP can be obtained according to a linear fitting formula of the diastolic pressure DBP and the pulse wave transit time PPT as follows:
wherein, b1、b0、b-2Primary term coefficients, constant term coefficients and negative quadratic term coefficients of the linear formula are respectively; for the object to be measured, a1、a0And b1、b0、b-2The value of (d) is fixed over time and its data can be determined by curve fitting, i.e. the diastolic pressure DBP can be calculated. It can be understood that the systolic pressure SBP and the diastolic pressure DBP are respectively calculated by combining the electrocardiosignals and the pulse wave conduction time PTT measured and then substituting the electrocardiosignals and the pulse wave conduction time PTT into the formulas, so that the blood pressure information of the human body is calculated. The above processing procedure of calculating the blood pressure information of the human body by using the electrocardiosignals and the pulse wave signals is the prior art, and will not be described in detail herein.
Compare in the intelligent wrist-watch or the bracelet of traditional structure, current pulse wave sensor mainly sets up at intelligent wrist-watch or bracelet back for radial artery to human wrist department detects. Due to the complex structure of human skin and the many differences of the tissue structures of different parts, the selection of the measurement site is crucial and the following factors should be reduced: the blood flow is relatively rich due to relatively weak external interference; secondly, the exposed part of the human body is selected as much as possible, so that the detection is convenient; the detection is convenient, the design difficulty is reduced, and the influence caused by objective factors is reduced.
