Experimental evaluation of polypropylene plasma separator

Abstract

The membrane used in this study was a polypropylene (PP) hollow fiber membrane. The PP membrane was evaluated for this efficiency with various protein fractions. The filtration rates of albumin, α₁ and γ globulin fractions were>90%, and α₂ and β globulin fractions were>80%. Plasma flow rate was measured as a fanction of transmembrane pressure and blood flow rate, e. g. mean was 39ml/min when blood flow rate was fixed at 100ml/min and transmembrane pressure 50mmHg. Hemolysis did not occure when transmembrane pressure was below 60mmlg. It is, therefore, expected that the unit will prove useful in clinical applications.
