ABSTRACT
Objective To evaluate the polyethersulfone(PES)hollow fiber membrane automatic plasma collector and its efficiency for separating plasma.Methods The plasma was collected by using the automated plasma collector with an innovating PES hollow fiber membrane plasma separator incorporated into a plasmapheresis device,using single needle.The concentration of total plasma protein was determined by Bio Rad method.Results 1)The sieving coefficients were over 95% during the plasma collection, and were stable.2)As the hematocrit (Hct) increased, the plasma collection rate decreased, but the plasma separation efficiency increased.At constant Hct of 0.45,the plasma filtration rate was 23.6ml/min,and the plasma separation efficiency was 52%.It took 20min to collect 200mL plasma.3)The maximum hemolysis rate after several circulation of collection was below 2.5%.Conclusion The plasma collection was satisfactorily performed, and the yield of plasma protein components was nearly the same as the plasma in whole blood.The PES membrane collector had a comparatively high efficiency of plasma separation.
