Abstract

The invention discloses a central arterial blood pressure measurement device, including brachial arterial blood pressure measurement, electrocardiogram measurement, radial artery blood pressure measurement, data processing, pulse wave transit time evaluation, pulse wave reflection coefficient evaluation, central arterial pressure calculation and data display, etc. module; the pulse wave transit time evaluation module is used to obtain the pulse wave transit time; the pulse wave reflection coefficient evaluation module divides the pulse wave into incident waves and reflected waves, and calculates the sum of the reflected wave amplitude and the sum of the incident wave and reflected wave amplitudes. The ratio of pulse wave reflection coefficient is obtained; the central arterial pressure calculation module calibrates the radial artery blood pressure waveform; at the same time, the pulse wave transit time and pulse wave reflection coefficient are input into the mathematical model to calculate the transfer function, and then use the transfer function and the calibrated The radial artery blood pressure waveform was calculated to calculate the central arterial pressure waveform. The invention can significantly improve the measurement accuracy of the central arterial pressure and reduce the measurement error.

Description

technical field [0001] The invention relates to blood pressure detection, in particular to a device for realizing individualized non-invasive central aortic blood pressure measurement by using peripheral arteries, and belongs to the technical field of medical devices. Background technique [0002] Central arterial pressure refers to the blood pressure at the root of the ascending aorta. Its systolic pressure represents the afterload of the heart and is related to left ventricular hypertrophy. Its diastolic pressure is the perfusion pressure of the coronary arteries, which also affects the functions of important organs such as the brain, kidneys and lungs. Therefore, it is closely related to cardiovascular disease. In recent years, with the continuous improvement of non-invasive measurement technology of central arterial pressure, people have paid more attention to and deepened the research on central arterial pressure, and it has been gradually used in the clinical observati...
