摘要
Abstract
Objective To study and evaluate the viscoelasticity of adult pig trachea in order to provide the experiment method and evidence for research of the human trachea and artificial trachea. Methods 50 ~ 5 000 N servo control tension tester was used for stretching of membranous part and annulus cartilaginous part in pig trachea respectively, and their stress relaxation and creeping property were analyzed. The curve table was made according to the experimental data and correlated equation. Results The equations and curve tables based on the experimental data of stress relaxation and creeping property in membranous part and annulus cartilaginous part of pig trachea showed: when the strain was stable, stress decayed exponentially with increase of time; when the stress was stable, strain increased exponentially with increase of time. Conclusion Pig trachea is suitable for features of stress relaxation and creeping property, so it is a bioviscoelastic soft tissue material.关键词
