  A STUDY ON BIOMECHANICAL PROPERTIES OF THE VALVE OF VEINES

  ma Airong,Shen Jingen(Shanghai Second Medical University)

  Abstract:Experiments of the tension and hysteresis and relaxation of the valve of veins in various sections were used in this part of the study. Results indicated that valve of vein had property of the hysteresis and that valve of vein in various sections had variant tensional forces. This study explored biomechanical property of the valve of the valve of veins, The data and results can be served as the selection of the artificial material of the valve and provide scientific basis for further study.

  Keywords:Veinal valve, Biomechanics, Stress
