23 Jul Simple small-caliber tissue engineering intravascular stent biomechanical property testing device
Abstract
The utility model discloses a simple small-caliber tissue engineering intravascular stent biomechanical property testing device. The testing device comprises a simple measuring channel assembly, a pressurizing assembly, a tissue engineering intravascular stent fixing assembly and an optical measuring assembly, the simple measuring channel assembly is composed of a pressurizing assembly, a plurality of small-caliber hollow pipes, a valve, a piston, a tissue engineering intravascular stent and a pressure gauge. The pressurizing assembly is composed of a spiral pressurizing piston cylinder with scales, an inner plug, a spring and a spiral pressurizing rod. The tissue engineering intravascular stent fixing assembly is composed of a movable stent, a fixed stent, a sliding block and a base witha movable track. The optical measurement assembly is composed of a scale, a high-speed camera and a computer. The bursting pressure of the tissue engineering intravascular stent can be measured by adjusting the simple measuring channel assembly; the compliance of the tissue engineering intravascular stent can be measured by adjusting the simple measuring channel assembly and cooperating with the optical measuring assembly.
