    • An apparatus (100) for extracorporeal blood cleaning includes a separation unit (110), at least two processing branches (120; 130) and a mixing unit (140). The separation unit (110) receives 5 incoming blood (B A) and divides off a first fraction (fC) from this blood. The first fraction (fC) contains predominantly blood cells. The separation unit (110) also divides off at least one second fraction (fP), which contains predominantly blood plasma. A first processing branch (120) processes the first fraction (fC) according to a first cleaning process, in which cell-bound substances are removed from the blood cells. As a result, a first cleaned fraction (fC c) containing washed blood cells is produced. A second processing branch (130) processes the second fraction (fP) according to a second cleaning process in which toxins bound on proteins within the plasma and/or toxins dissolved in 15 the plasma are removed, and a second cleaned fraction (fP c) is produced. The second cleaning process is different from the first cleaning process. Thereby each process can be tailored for the requirements of the respective fraction (fC, fP). The mixing unit 20 (140) receives the first and second cleaned fractions (fC c, fP c, combines these fractions (fC c, fP c, and outputs cleaned whole blood (BV).
    • 用于体外血液清洁的装置(100)包括分离单元(110),至少两个处理分支(120; 130)和混合单元(140)。 分离单元(110)接收5个进入的血液(B A)并从该血液中分离第一分数(fC)。 第一部分(fC)主要含有血细胞。 分离单元(110)还分离出主要含有血浆的至少一个第二级分(fP)。 第一处理分支(120)根据第一清洁处理处理第一馏分(fC),其中细胞结合物质从血细胞中移除。 结果,产生含洗涤血细胞的第一清洗级分(fC c)。 第二处理分支(130)根据第二清洗过程处理第二馏分(fP),其中除去等离子体中溶解的血浆中的蛋白质和/或溶解于血浆中的毒素的毒素和第二清洗部分(fP c) 生产。 第二次清洗过程与第一次清洗过程不同。 因此,可以针对各个部分(fC,fP)的要求来定制每个过程。 混合单元20(140)接收第一和第二清洗级分(fC c,fP c,将这些级分(fC c,fP c)组合并输出清洁的全血(BV)。
