膜血浆除去法是用超滤膜从全血中分离血浆,这种方法遇到的问题是浓度极化,即在膜表面聚集细胞和溶质。在血浆去除法中,用电场与超滤相结合是一种解决这个问题的有效方法.本文作者用电场通过转移膜表面带负电荷的细胞和溶质来控制浓度极化。作者测定了施加电场前后血浆流量和蛋白浓 Membrane plasma removal is the separation of plasma from whole blood using an ultrafiltration membrane. The problem encountered with this method is concentration polarization, ie, the accumulation of cells and solutes on the membrane surface. In plasma removal, the combination of an electric field and ultrafiltration is an effective solution to this problem.The authors use an electric field to control the concentration polarization by transferring negatively charged cells and solutes on the surface of the membrane. The authors measured plasma flow and protein concentration before and after application of an electric field
