摘要
采用ASTM直接接触法和间接接触法对六种不同材料的溶血性能进行比较,结果显示用两种方法检测的聚乙烯、丁腈手套和橡胶#2的溶血等级判定结果是一致的,而乳胶手套、橡胶#1和Buna橡胶用两种方法检测的溶血等级判定结果不一致,且乳胶手套和Buna橡胶的溶血指数差异显著。我们分析了采用这两种方法检测,导致结果不一致的原因,为医疗器械或材料的溶血性能检测提出了一些建议,为新标准的发布和实施提供了数据支持。
In this study,the direct and indirect methods of ASTM were used to assay the hemolytic properties of 6 kinds of different materials. The results showed that the hemolytic grade using the two methods were basically consistent on the Polyethylene,Nitrile glove and Rubber #2. The hemolytic grade using the two methods were inconsistent on the Latex glove,Rubber #1 and Buna rubber.The hemolytic index of the two methods of the Latex glove and Rubber #1 were significant different. We analyze the causes of the inconsistent and offer some suggestions about the measurement of hemolytic properties of medical devices or materials and supply data support for the publication and execution of the new standards.
