Physiological Dynamic Blood Flow Simulation for Traumatic Aortic Rupture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current models for traumatic rupture of the aorta (TRA) research often ignore the impact of physiological dynamic blood flow, which is a critical factor in inducing TRA during vehicle collisions, due to the complexity of the cardio-aortic system.
Innovation Solution
A method and apparatus for simulating physiological dynamic blood flow by acquiring related parameters and constructing functions such as circulation dynamic loading, LV dynamic blood pressure, dynamic arterial blood flow volume, and cyclic opening/closing activation of the aortic valve, to create a physiological dynamic blood flow model that accurately simulates the cardio-aortic system's behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physiological dynamic blood flow is included in the model, then the accuracy of TRA research is improved, but the device complexity increases
Solution Approach 1:
The patent divides the complex cardio-aortic system into separate functional modules: a blood flow simulation module that models dynamic blood flow characteristics, a collision load module that applies external forces, and a trauma prediction module that integrates these elements. This segmentation allows each module to be developed and validated independently while maintaining overall system accuracy.
Solution Approach 2:
The patent introduces a blood flow simulation module as an intermediary component that bridges the gap between static anatomical models and dynamic trauma analysis. This intermediary module captures the physiological blood flow characteristics and transmits their effects to the trauma prediction system, enabling accurate TRA research without requiring the entire system to be overly complex.
2Measurement precision
If the cardio-aortic system is modeled with high fidelity, then the simulation accuracy is improved, but the ease of manufacture decreases
Solution Approach 1:
The patent creates a virtual digital model that copies the essential physiological characteristics of the cardio-aortic system without requiring physical construction of complex anatomical structures. The blood flow simulation module uses computational algorithms to replicate dynamic blood flow patterns, eliminating the need for manufacturing complex physical models while maintaining high simulation accuracy.
Solution Approach 2:
The patent employs parameter-based modeling where physiological characteristics are represented through adjustable parameters (flow rates, pressure gradients, vessel compliance) rather than fixed geometric structures. This allows the model to be constructed and modified through software parameter settings rather than complex manufacturing processes, significantly improving ease of implementation while maintaining accuracy.
