Abstract

The invention provides a central arterial blood pressure measurement method based on a human artery 3D blood vessel network model. A plurality of steps in the simulation process are programmed into parameterized instructions through the ANSYS secondary development language APDL. Outlet parameters of the corresponding blood vessel network model are given for measured different radial artery pressure waveform signals of the left and right hands, and the corresponding personalized simulation is calculated to obtain the central arterial pressure waveform. The plurality of steps include defining aUPF module, setting regional boundary conditions, setting a solver to perform calculation, performing blood vessel and blood grid division, loading a load, visually solving central arterial blood pressure waveform and blood vessel deformation parameters and the like, and analyzing results. According to the method, non-invasive operation is performed, and the data display is intuitive and accurate;and at the same time, the simulation change conditions of blood in blood vessels can be observed in real time, which provides a certain basis for the clinical diagnosis, treatment and scientific research of cardiovascular diseases.

Description

technical field [0001] The invention relates to the technical fields of physiology and clinical medicine, in particular to a method for measuring central arterial blood pressure based on a 3D vascular network model of human arteries. Background technique [0002] According to the statistics of Medical Daily in 2016, the number of hypertensive patients in the world has exceeded 1.1 billion, and as many as 3 million people die from cardiovascular diseases every year. Due to the close relationship between the treatment of cardiovascular diseases and hemodynamics, in recent years, the fluid-solid coupling of arteries and the discovery of the etiology from the perspective of mechanics have become research hotspots at home and abroad. For example, the WA-820 digital impedance blood flow detector is used to measure the hemodynamic indicators and analyze the dynamic changes of blood flow; the intracranial vascular tomography technology is used, combined with the 3D fluid dynamics mo...
