ABSTRACT:
A tubing or harness set is provided having first and second portions sequentially applicable to a microprocessor-controlled hemapheresis instrument for generating platelet concentrate. The first portion includes a reservoir having dual compartments and a separator. The instrument and the first portion of the harness set alternately collect whole blood from the donor and reinfuse packed cells into the donor while simultaneously continuously separating whole blood into packed cells and platelet-rich plasma. Upon collection of a predetermined quantity of platelet-rich plasma, the donor is disconnected form the phlebotomy needle of the harness, the first harness portion is removed from the instrument and the second harness portion is applied to the instrument. The second harness portion includes a separator for receiving platelet-rich plasma from the collection container of the first harness portion and separating such plasma into platelet concentrate and platelet-depleted plasma.
