A method and device for continuous measurement of non-invasive arterial blood pressure

Abstract

The invention discloses a non-invasive human body arterial blood pressure continuous measurement method and equipment. The non-invasive method for continuous measurement of human central arterial blood pressure includes: the method of calculating the individualized parameters of the subject's arterial vascular network model from the collected radial and brachial artery pulse waveforms, and calculating the radial artery blood pressure from the radial artery pulse wave velocity and arterial vascular network parameters The method of systolic blood pressure, diastolic blood pressure and blood pressure waveform, the method of calculating the ascending aorta-radial artery transfer function, and then the method of calculating central blood pressure. The non-invasive human central arterial blood pressure continuous measurement device consists of a signal processing and analysis unit, a pulse wave and motion signal acquisition unit worn on the wrist, and an ECG and motion signal acquisition unit worn on the chest. The present invention simultaneously monitors ECG, radial artery blood pressure and central arterial blood pressure, as well as motion and posture, analyzes heart rate and ECG morphological parameters, arterial network model parameters and blood pressure parameters, especially the waveform of central arterial pressure under various exercise states It is of great significance for the prevention and control of cardiovascular diseases, especially the prevention and control of high-risk diseases such as hypertension and coronary heart disease.

Description

technical field [0001] The invention belongs to the technical field of medical detection, in particular to a non-invasive continuous blood pressure measurement and monitoring system. Background technique [0002] Continuous measurement of blood pressure is necessary for the prevention, diagnosis, treatment and control of hypertension. Hypertension is an important risk factor for cardiovascular disease. However, patients with hypertension often do not have obvious clinical manifestations until the occurrence of target organ damage (TargetOrganDamage, TOD) to attract attention. Therefore, it is of great significance to monitor and detect hypertension early and start treatment before TOD. The traditional 24-hour blood pressure monitors on the market now use the inflation method to measure and record blood pressure regularly using a program. Its disadvantages are low precision, interference with the measured person, and continuous measurement cannot be obtained. The Chinese ...

Problems solved by technology

Although the above method has been verified by a large number of clinical trials, there are the following problems: (1) The general transfer function method and the multi-point moving average method come from clinical experience and have no theoretical support

There must be a problem with the accuracy of the results of these two methods, and important information for diagnosis has been lost.
