Problems solved by technology

At present, the commonly used non-invasive blood pressure measurement methods include Korotkoff sound auscultation and oscillometric method. These two methods only use the arteries (such as brachial artery and ankle artery) that are easy to bind the inflatable cuff. For other arteries such as carotid artery and femoral artery Arteries are not suitable for this non-invasive blood pressure measurement method

Abstract

The invention discloses a blood pressure parameter estimation system and method based on waveform analysis technology. The module processes the input data, and the output module of the system outputs the diastolic blood pressure, systolic blood pressure, pulse pressure of the part to be measured and the pulse wave transit time from the brachial artery to the measurement part; the brachial artery pulse wave signal and the pulse wave of the part to be measured The signals are a group of pulse wave signals collected at synonymous moments. The invention aims at accurately estimating the pulse wave transit time, and at the same time realizing non-invasive measurement of blood pressure in different parts of the human body, especially the arterial blood pressure at the blood pressure part which is not easy to directly measure.

Description

technical field [0001] The invention relates to the technical field of biomedical engineering, in particular to a blood pressure parameter estimation system and method based on waveform analysis. Background technique [0002] Cardiovascular disease is the main cause of disability and premature death worldwide. According to statistics from the World Heart Federation, 1 out of 3 deaths worldwide is caused by cardiovascular disease. In my country, in recent years, with the continuous improvement of residents' living standards, continuous changes in dietary structure, and the deterioration of the natural environment, the prevalence, morbidity and mortality of cardiovascular diseases in the middle-aged and elderly people have been increasing year by year. Early detection of changes in heart and blood vessel function, and through strengthening lifestyle intervention and appropriate drug treatment can reduce the harm of cardiovascular disease to human life and health. [0003] Dec...
