Abstract

The present invention relates to the technical field of non-invasive blood pressure detection, in particular to a non-invasive blood pressure detection method based on photoelectric green light pulse and electrocardiogram, which includes a multi-mode bioelectric sensor and performs the following steps: by adopting a conventional method based on photoplethysmography PPG , extract the characteristic parameters in the PPG signal, establish the measurement model of human blood pressure, and get the calibration parameters closely related to the blood pressure value of the human body through blood pressure calibration and calibration, and then use these calibration parameters to carry out the measurement based on PPG waveform and ECG The blood pressure measurement of the pulse wave of the waveform; then by adopting the pulse wave velocity measurement method based on the PPG waveform and the ECG waveform, a multi-parameter blood pressure estimation model is established, and finally the data measured by the two are compared, analyzed and corrected; the present invention uses the PPG waveform and the ECG waveform Waveform mixed-mode detection can effectively improve the inspection accuracy; it has a high degree of hardware compatibility with multi-mode bioelectric sensors, and also creates good conditions for the portability and miniaturization of the product.

Description

technical field [0001] The invention relates to the technical field of non-invasive blood pressure detection, in particular to a non-invasive blood pressure detection device based on the combination of photoelectric green light pulse and electrocardiogram. Background technique [0002] With the development of science and technology, non-invasive blood pressure detection is becoming more and more accurate, and due to its non-invasiveness, convenience and practicality, its application in daily measurement is also becoming more and more extensive. However, traditional blood pressure measurement is bound by the inflatable cuff of the sphygmomanometer and cannot achieve long-term continuous blood pressure monitoring. In order to get rid of such problems, many scholars have carried out research on non-invasive and continuous blood pressure monitoring based on PPG. The current research on non-invasive blood pressure monitoring based on PPG can be divided into three types: the blood...
