机采血小板由于其产品纯度高、抗原少、治疗效果好等原因,临床使用量呈逐年上升趋势。机采血小板成本较高,且血源紧张,因此在机采血小板时应尽量避免发生血小板成品因质量问题而报废。冲红是指在使用血细胞分离机采集血小板过程中,有大量红细胞混入,是影响机采血小板采集失败的一个主要原因~(〔1〕)。按照中华人民共和国单采血小板质量要求,红细胞混入量≤8.0×109个/袋~(〔2〕)。为了减少冲红现象发生,避免血源和物料的浪费,
Due to the high purity of the product platelets, antigen-less, the treatment effect is good and other reasons, the clinical use of the platelets showed an upward trend year by year. Machine-drawn platelets higher cost, and blood tension, so the platelet should be taken to avoid the occurrence of platelet quality problems due to scrapped. Chong red refers to the use of hemocyte separator platelet collection process, a large number of mixed red blood cells, is the main reason for the failure of collecting platelet collecting ~ (〔1〕〕. According to the People’s Republic of China apheresis platelet quality requirements, the amount of mixed erythrocytes ≤ 8.0 × 109 个 / bag ~ (〔2〕). In order to reduce the red red phenomenon, to avoid the waste of blood and materials,
