静脉瓣膜的生物力学特性初探

　　摘　要：本文通过不同部位静脉瓣膜的拉伸、滞后、压力松弛实验，表明静脉瓣膜的加载卸栽滞后现象和不同部位静脉瓣膜具有不同的抗张能力，作出对静脉瓣膜的生物力学性质的探索，为人造静脉瓣膜材料选择决定，提供参考指标。

　　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.
