Objective To evaluate the performance of BBS926,a new blood cell processing instrument of Nigale Biomedical Co.,Ltd. Methods Blood samples treated by two processing methods were the control groups: one was remove glycerol from frozen-thrawed reb blood cells with ACP215( group 1),the other was red blood cell suspension treated by hand washing( group 2). The frozen-thrawed red blood cells and red blood cell suspension treated with BBS926 was the experimental group( group 3). The appearance,blood volume,residual white blood cell level,hemoglobin concentration,free hemoglobin concentration( FHb) in supernatant,in vitro hemolysis rate,residual glycerol level and bacterial contamination were measured according to the GB18469-2012edition Quality Requirements For Whole Blood And Blood Components. Results FHb concentration was( 0. 28 0. 07) g /L in group 1 and( 0. 40 ± 0. 16) g /L in group 3. The hemolysis rate in vitro in group 1 and group3 both met the national standard and the hemolysis rate in group 1( 0. 13 ± 0. 02) % was significantly lower than that goup3( 0.34 ±0.20) %. There was significant differences between group 2 and group 3 for the Hgb concentraion [( 56.78 ±7.75)g vs( 50. 64 ± 3. 82) g],FHb concentration [( 0. 32 ± 0. 18) g /L vs( 0. 62 ± 0. 42) g /L] and hemolysis rate[( 0. 08 ± 0.05) % vs( 0. 17 ± 0. 11) %]. However,,all the indicators above met the national standard. Conclusion BBS926 has advantages such as automation,depollution and high efficiency so it can be used to treat red blood cells for clinical transfusion.
