The artificial blood membrane rupture strength tester is a physical performance testing device specifically designed for artificial blood membranes. By applying controllable pressure or tensile load, it simulates the dynamic stress environment that blood vessels experience in the body until the membrane ruptures. Its core function is to determine the critical pressure value when the film ruptures, and record the pressure change curve during the rupture process, providing quantitative basis for evaluating the pressure resistance, sealing performance, and clinical safety of artificial blood.

1、 Principle

The principle of the tester is based on mechanical simulation and data acquisition technology, mainly divided into the following steps:

Pressure loading: Fill the vascular prosthesis sample with liquid or gas at a controllable rate of pressure change to simulate the dynamic pressure environment in blood circulation.

Data monitoring: Equipped with high-precision pressure sensors and flow meters, real-time monitoring of pressure changes, flow data, and sliding parameters.

Fracture determination: When the pressure increases to the point where the film ruptures, the sensor captures the pressure value at the moment of rupture and records it as the rupture strength; At the same time, the system generates pressure time curves to analyze the deformation behavior and rupture mechanism of the thin film.

Result output: Output a test report through an onboard printer or digital interface, including the average fracture strength, standard deviation, and opening area, providing a scientific basis for performance evaluation.
