Abstract
The purpose of this study is to clarify the mechanism about behavior of artery by experimental approach. As the first step, two evaluation methods of the arterial deformation characteristics are introduced to analyze the mechanism. One of them is to identify the viscoelasticity from blood pressure and pulsatile deformation of tube. The other one is to evaluate the deformation characteristics from pressure and reaction force by pinching of the vessels. These methods are validated in artificial device which imitate the circulatory organ of human. As the result of the validation, the viscoelastic method can evaluate separately the elasticity and the viscosity of the tube at the same time. Further, it is suggested that the possibility which the pinching method can identify the elasticity of the tube effectively.
