摘要:

去白細(xì)胞采輸血器是用于過濾全血或紅細(xì)胞懸液中白細(xì)胞的醫(yī)療器械類產(chǎn)品,為保證其臨床應(yīng)用的安全性,本文對去白細(xì)胞采輸血器(型號(hào):NGL/RF-XZ-200)進(jìn)行血液相容性體外評價(jià)。選擇去白細(xì)胞采輸血器的3個(gè)主要部件:軟管、塑料血袋和去白細(xì)胞濾器濾膜為試驗(yàn)樣品,以進(jìn)口同類產(chǎn)品作為參照,按照GB/T 16886.4—2003和GB/T 14233.2—2005標(biāo)準(zhǔn)的要求和方法,進(jìn)行溶血、PTT以及體外自發(fā)性血小板聚集3個(gè)體外血液相容性指標(biāo)測試。結(jié)果顯示試驗(yàn)樣品溶血率小于5%,樣品凝血時(shí)間和血小板最大聚集率與參照樣品無顯著性差異(P>0.05)。該結(jié)果表明去白細(xì)胞采輸血器對血液成分和功能無明顯不良影響,具有良好的血液相容性。

The blood collection and transfusion equipment with leukocyte filtration is used in the filtration of whole blood or red blood cell suspension. In vitro evaluation of hemocompatibility was conducted to ensure its safety when the product is used in clinic. Three major components of the product, the flexible pipeline, plastic blood bag and filtration membrane, were chosen for the samples, and the same parts from same type import products for the reference material. According to the GB/T 16886.4—2003 and the GB/T 14233.2—2005, three parameters of hemolysis, PTT and the blood platelet aggregation assay were tested. The experimental results showed that the hemolysis rates of the samples were below 5 per cent. There were no significant differences in the partial thromboplastin time and the platelet maximum aggregation rate between the samples and the reference materials (P>0.05). These results indicated that the blood collection and transfusion equipment with leukocyte filtration emerged little harmful effects on the blood ingredients and functions, and it was of good hemocompatibility.
