Abstract
The authors intend to develop rapid and convenient method for plasma extraction. This method is able to progress treatment speed and inspection accuracy in biochemical analysis. Plasma extraction was tried with small sized hollow-fiber plasma separator. Saline was added to membrane to avoid hemolysis. Pump and syringe were used to feed blood. Filtrate was evaluated by sieving coefficient for Total Protein and degree of hernolysis. Maximum filtrate flux was obtained from polyethylene membrane's plasma separator at a transmembrane pressure of 100 mmHg and a wall shear rate of 5000s-1.2 ml of plasma was obtained from 11ml of blood in 14 seconds with pump, and in 75 seconds with syringe. Hemolysis was not confirmed. Real sieving coefficient were calculated from volumes of added saline and obtained plasma.
