Description

technical field [0001] The present invention relates to the field of physiological dynamic blood flow simulation, and more specifically refers to a physiological dynamic blood flow simulation method, device, computer equipment and storage medium. Background technique [0002] Cardiovascular trauma and related conditions are currently one of the leading causes of human death worldwide. Especially in automobile collision accidents, traumatic aortic rupture (Traumatic Rupture of the Aorta, TRA) accounts for more than 20% of all accident deaths, and is the second leading cause of death of occupants after craniocerebral injury. Traumatic aortic rupture is an acute and critical injury. More than 85% of people with aortic injury will die at the scene of the accident, and more than 50% of survivors will die within 24 hours if they do not receive effective treatment. However, it is generally not easy to detect aortic injury during emergency rescue of accident injured persons. Even ...

AI Technical Summary

Problems solved by technology

Preliminary work has found that the sudden change in blood flow pressure under the combined action of occupant's chest impact load and aortic physiological dynamic blood flow has an important impact on aortic rupture in car crashes, but limited by the complexity and difficulty of research of the heart-aortic system, it has been Some models mostly ignore the influence of physiological and dynamic blood flow in the human aortic system
