Development of a new system for donor plasmapheresis by the membrane separator using a single needle

Abstract

In order to reduce donors' restriction and pain, a new plasma collection system requiring only one needle (DP-1S) was developed by us. With a cellulose-tri-acetate hollow fiber type plasma separator (PEX-25). our system was clinically evaluated and proved to be safe and effective every procedure was carried out without showing any complication of the donors or abnormal laboratory findings. The duration of the precedure was within 1 hour for collecting 500ml o f cell-free and hemolysis-free plasma.
