单采血小板是应用血细胞分离机在全封闭的条件下,自动将符合要求的献血者血液中的血小板分离并悬浮于一定量血浆内的单采成分血[1]。近年来随着输血医学的发展,单采血小板因其具有纯度高、白细胞污染低,输血传播疾病及不良反应发生率低,临床治疗效果明显等优点被广泛应用[2]。然而在使用血细胞分离机进行血小板采集过程中,可能会混入大量红细胞,出现冲红现象,既影响血小板的质量和血小板临床输注效果,又造成耗材的浪费。洛阳
The apheresis platelet is a apheresis blood which is separated and suspended in a certain amount of plasma by a blood cell separator under fully enclosed conditions and automatically meets the requirements of blood platelets in the blood of donors. In recent years, with the development of transfusion medicine, apheresis platelets are widely used due to their advantages of high purity, low leukocyte pollution, low transfusion-transmitted diseases and adverse reactions, and obvious clinical treatment effects [2]. However, in the process of platelet collection using a blood cell separator, a large amount of erythrocytes may be mixed and red flushing occurs, affecting not only the quality of platelets and the clinical effect of platelet transfusion, but also the waste of consumables.
