ABSTRACT:
The system includes a plasmapheresis instrument and a harness set applied to the instrument. The harness set has a single venepuncture needle and is configured, when applied to the instrument, to pump blood from a donor through a separator for collection of its constituent parts in a reservoir and a collection container, respectively. During an infusion cycle, which alternates with the collection cycle, the blood constituent from the reservoir and a replacement fluid are mixed externally of the reservoir and pumped to the donor.
