摘要
本文设计一种由胶原和高分子聚合物组成的新型生物一人工复合血管。其研制过程是将包绕有聚酯网的硅胶棒埋入羊的皮下组织,再将形成的经聚酯网为支架的胶原管经醛化处理。作者通过肉眼和SEM观察提出了研制生物——人工复合血管的要点:聚酯网网孔要合适,其与硅胶棒的间隙要恰当,理化处理方法更要选择好。
This paper introduces a new designed biosynthetic vascular graft made by collagen and high Polymer. Polyester mesh-supported collagen tubes grown in the subcutaneous tissue of sheep around Silastic mandrils were tanned in glutaradehyde. Through the observation with the naked eyes and SEM the main points were pointed for the production of the new grafts. The size of polyester mesh, the space between polyester mesh and silicone rubber and the method of physical and chemical treatment for preparing the grafts should be proper.
