【摘要】 血液润滑人工器官具有其它润滑剂不可比拟的优越性,但由于血液的特殊性,其润滑性能受到诸多因素的影响,对影响血液润滑性能的主要因素进行了分析探讨。指出血液的组分变化、剪切率、血细胞的聚集、变形、温度等因素的改变会引起血液粘度的变化,影响血液的流动性,进而影响到血液的润滑性能;摩擦界面的材料表面特性会影响到吸附膜的组成,从而影响到血液润滑状态。更多还原

【Abstract】 Comparing with other lubricant,blood has great competitive advantages used as the lubricant of artificial organs,however its special blood lubricating properties are effected by many factors.The main factors affecting blood properities were analyzed and discussed.It is discovered that the change of blood component,shear rate,erythrocytic deformability and aggregation and the temperature will cause the change of viscosity,which influences blood fluidity,moreover it affects the lubricating properties;the material’s surface properties of the friction interface can influence the component of the adsorption film and then affect the lubricating film while blood used as lubricant.更多还原
