BLOOD PROCESSING SYSTEMS AND METHODS TO COLLECT MONONUCLEAR CELLS.

摘要

SYSTEMS AND METHODS FOR SEPARATING COMPLETE BLOOD MONONUCLEAR CELLS BY TURNING A SEPARATION COMPARTMENT (38) AROUND A ROTATION AXIS. THE COMPLETE BLOOD IS INTRODUCED FROM AN ENTRY REGION (74) IN A FIRST REGION (76) OF THE CHAMBER DURING ITS ROTATION TO SEPARATE THE COMPLETE BLOOD IN ITS PLASMATIC COMPONENT, ERYTHROCYTES AND INTERFACE BETWEEN ERYTHROCYTES AND PLASMATIC COMPONENT. THE INTERFACE CONTAINS MONONUCLEAR CELLS. DURING THE TRANSPORTATION OF THE COMPLETE BLOOD BY THE FIRST REGION, THE PLASMATIC COMPONENT IS COLLECTED IN THE FIRST REGION, WHILE THE ERYTHROCYTS ARE COLLECTED IN A SECOND REGION OF THE CHAMBER LOCATED AWAY FROM THE ENTRY REGION. BELOW, Erythrocytes are transferred to the second region (78) in a direction of reverse flow to the region of entry. BY TRANSFERRING THE Erythrocytes to the second region, the mononuclear cells are collected in the first region.
