目的探讨Trima单采机采集双份血小板的质量及采集参数的设置。方法采集符合体检标准的献血者血小板15例,对采集后的血小板进行血小板、白细胞进行计数。结果应用Trima单采机采集的血小板白细胞残留量为(0.82±0.16)×106个,血小板含量经参数不断调整后也达到5.0×1011个/袋,符 Objective To investigate the quality and parameters of double platelets collected by Trima single machine. Methods Fifteen blood platelets were collected according to the physical examination standards, and the platelets and white blood cells were collected after the collection. Results The residual amount of platelet leukocytes collected by Trima single machine was (0.82 ± 0.16) × 106, and the platelet content reached 5.0 × 1011 cells / bag after the parameters were adjusted
