聚氨酯在医疗器械领域的应用

Application of Polyurethane in the Field of Medical Apparatus and Instruments

传统的陶瓷、金属材料由于缺乏刚性、柔性,在被用于组织修补和体内植入后存在不同的不良反应,而塑料材料因为存在添加剂或其他溶剂残留,会对人体造成不同程度的损害。因此,兼具弹性与柔性、良好生物相容性且无毒的聚氨酯引起研究者的广泛关注。该研究首先介绍了聚氨酯的合成工艺,总结了其主要结构及性能特点,然后介绍了其在医疗器械领域的应用情况及研究进展。

For lack of rigidity and flexibility,traditional ceramics and metal materials have different side effects on tissue repair and in vivo implantation.However,some plastics have different degrees of damage to human body due to the existence of additives or other solvent residues.Therefore,polyurethane,which has the benefits of elasticity,flexibility,good biocompatibility and non-toxic,has attracted extensive attentions of researchers.This study first introduced the synthesis process of polyurethane,summarized its main structure and performance characteristics,and then introduced its application status and research progress in the field of medical apparatus and instruments.
