具有血液相容性的高分子材料

Novel Polymer Material with Haemocompatibility

随着现代医学的发展,越来越多的人造器官从实验室研究进入临床应用,以取代功能衰竭或已坏死的人体器官。如人造血管,人造心脏和人造骨头。心脏起搏器、血管扩张器等装置也常通过心血管外科手术植入体内相应部位改善其生理功能。美容、整容手术中也常用一些人造材料作为填料以矫正某些部位的外形。在对危重病人的监护中,需及时获取体内尤其是血液中一些生物化学物质变化的信息,植入式传感器的应用为这种实时临床监测提供了一条途径。

Clinically,most of blood-contacting devices such as invasive sensors,dialysis membranes, vascular prostheses and stents often havt poor brood compatibility.The process of rhombus- formation in blood-contacting surfaces and the possible routes to prevent the coagulation in these surfaces was reviewed.A novel polymer material with haemocompatibility was used and the properties of anti-thrombus were discussed.
