Embodiment 1

[0024] Embodiment 1 A kind of non-invasive continuous blood pressure measurement method

[0025] Proceed as follows:

[0026] (1) Collect the synchronous signal of the subject's ECG and pulse wave;

[0027] (2) Smooth the synchronous signal of the subject's ECG and pulse wave, detect the peak point of the R wave of the ECG signal and the characteristic point of the pulse wave and mark the position, and calculate the conduction time of the pulse wave through the position difference between the two And the corresponding conduction ratio of the pulse wave;

[0028] (3) The conduction time and conduction ratio of the obtained pulse wave are brought into the personalized blood pressure parameter model, and the continuous systolic blood pressure of the subject is calculated.

[0029] Wherein, the personalized blood pressure parameter model is established by the following method:

[0030] (1) Measure the subject's blood pressure, collect the synchronous signal of the subject's ECG...

Abstract

The invention relates to a noninvasive continuous blood pressure measuring method, comprising the following steps: acquiring a synchronizing signal of electrocardio and pulse waves of a subject; performing smoothing processing on the synchronizing signal of electrocardio and pulse waves of the subject, detecting an electrocardio signal R wave peak value point and characteristic points of the pulse waves and marking positions, calculating to obtain conducting time of the pulse wave and conduction ratio of corresponding pulse wave; and bringing the conducting time and conduction ratio of the pulse wave into an individualized blood pressure parameter model, and calculating to obtain continuous systolic pressure of the subject. A new parameter, that is conduction ratio, is introduced in the existing noninvasive blood pressure model, and an individualized parameter model is established for each subject, so as to obtain more accurate blood pressure results. The method is simple in operation, high in accuracy, and provides important basis for clinic blood pressure monitoring, home monitoring, and early warning, and monitoring of hypotensive drugs.

Description

technical field [0001] The invention relates to a noninvasive continuous blood pressure measurement method, in particular to a continuous blood pressure measurement method based on pulse wave transit time and conduction ratio. Background technique [0002] Arterial pressure is an important physiological parameter reflecting the circulatory function of the human body, and it is also an important basis for clinical diagnosis of diseases, observation of treatment effects, and judgment of prognosis. Noninvasive continuous blood pressure measurement can monitor blood pressure changes in each cardiac cycle, so noninvasive continuous blood pressure measurement is of great significance in clinical blood pressure monitoring, home monitoring and early warning, and monitoring of antihypertensive drugs. [0003] In recent years, the non-invasive continuous blood pressure measurement method using pulse wave transit time (PWTT) or conduction velocity (PWV) to calculate blood pressure has ...
