AI Technical Summary
Existing cardiovascular implant fatigue wear tests cannot accurately simulate the complex biomechanical environment inside the human body in dynamic fatigue testing machines, resulting in low reliability of test results.
A cardiovascular implant fatigue and wear testing system is designed, including an environmental simulation module, a condition setting module, a cavity configuration module, a status monitoring module, and a result output module. By simulating patient group characteristics, biomechanical properties of biological tissue elements, and cardiac respiratory motion patterns, cyclic loads and fluid flow modes are set to monitor the operating status of the implant in real time and analyze fatigue life and wear degree.
It improves the reliability of fatigue wear test results for cardiovascular implants, ensures that test results are closer to actual conditions, assesses the durability and reliability of implants, reduces stress concentration and fatigue damage, and improves biocompatibility.
