狭义的生物医用材料,是指长期与活体组织接触或植入活体内部,起某种生物功能的材料。而广义的生物医用材料还包括制造生物医药的原材料、医学诊断试剂、药物送达释放体系用材以及一次性使用的医用材料。生物医用材料及其制品已广泛应用于人体植入体。以现代科技手段生产的生物医用新材料及其制品在代替、修补、辅助修复人体组织器官上取得了显著的进展,医学上已广泛用于制造人工心脏、心脏瓣膜、人造血管、人工肾、人造皮肤、人工骨,以及药物释放体系等。已显示出较显著的社会和经济效益,成为一个新兴
In the narrow sense, biomedical materials refer to materials that have long been in contact with living tissue or implanted inside the living organism and that serve a certain biological function. The broad range of biomedical materials also include raw materials for the manufacture of biopharmaceuticals, medical diagnostic reagents, materials for delivery of drug delivery systems, and disposable medical materials. Biomedical materials and their products have been widely used in human implants. The new biomedical materials and products made with modern scientific and technological means have made remarkable progress in replacing, repairing, and repairing human tissues and organs, and have been widely used in medicine to manufacture artificial heart, heart valves, artificial blood vessels, artificial kidneys, and artificial Skin, artificial bones, and drug delivery systems. Has shown significant social and economic benefits, becoming a new one
