Noninvasive continuous arterial blood pressure measuring method and equipment

Abstract

The invention discloses a noninvasive continuous human body arterial blood pressure measuring method and equipment. The noninvasive continuous human body central arterial blood pressure measuring method comprises the steps as follows: calculating individualization parameters of a to-be-measured person artery blood vessel network model according to acquired pulse wave forms of radial arteries and brachial arteries; calculating radial artery blood pressure systolic pressure, diastolic pressure and blood pressure wave forms according to radial artery pulse wave speeds and artery blood vessel network parameters; calculating ascending aorta-radial artery transfer functions; further calculating central arterial blood pressure. The noninvasive continuous human body central arterial blood pressure measuring equipment consists of a signal processing and analyzing unit, a pulse wave and motion signal acquisition unit worn on the wrist as well as an electro-cardio and motion signal acquisition unit worn in front of the chest. According to the method and the equipment, electrocardiograms, the radial artery blood pressure, the central arterial blood pressure as well as motions and postures are monitored simultaneously, heart rate and electro-cardio morphological parameters are analyzed in various motion states, artery network model parameters and blood pressure parameters, particularly central arterial pressure wave form parameters, are analyzed, and the method and the equipment have great significance for prevention and control on cardiovascular diseases, particularly for prevention and control on high-risk diseases such as the hypertension, the coronary heart disease and the like.

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 (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 patent CN1477942A a...
