Continuous measurement method, device and system for blood pressure

Abstract

The invention provides a continuous measurement method, device and system for blood pressure. The method comprises the steps that a measurement signal of a pulse wave of the human body is acquired; acharacteristic value of the measurement signal is extracted, wherein the characteristic value comprises a waveform characteristic of a pules wave signal; the characteristic value is input to a pre-built continuous blood pressure model, and a continuous blood pressure signal of the human body is output, wherein the continuous blood pressure model is built through neural network training according to the pules wave signal of the human body. According to the continuous measurement method, the continuous blood pressure can be measured in a noninvasive mode, and the measurement mode is convenient and fast; meanwhile, through a neural network training mode based on the pulse wave, connected signals are easily obtained, characteristic parameters are easily processed, the method is insensitive tothe quality of the connected signals, errors are small, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of medical measurement, in particular to a continuous blood pressure measurement method, device and system. Background technique [0002] Blood pressure is one of the most important physiological parameters of the human body, which can reflect the functional status of the human cardiovascular system and is an important basis for clinical diagnosis and treatment observation. Changes in blood pressure are affected by a variety of factors, often accompanied by changes in menstrual cycles, mood swings, and external stimuli, resulting in large differences in the results of each measurement. The blood pressure results of intermittent measurement are increasingly unable to meet the needs of clinical monitoring and medical research, while the continuous measurement method can obtain the blood pressure of each heartbeat cycle. In clinical and medical research, especially for hypertension and cardiovascular and cerebr...

Problems solved by technology

The indirect measurement method obtains the blood pressure indirectly by detecting the pulsation of the arterial wall, the change of the blood vessel volume or the characteristics of the pulse wave. However, most of the existing indirect measurement methods are sensitive to the quality of the sampling signal, and the calculation method is immature and the calculation complexity is high. , resulting in lower measurement accuracy

[0004] In view of the low accuracy of the above-mentioned existing continuous blood pressure measurement methods, no effective solution has been proposed
