Abstract
A plasmapheresis system and a method for operating a plasmapheresis system are provided by which the reservoir for the concentrated red blood cells (RCC) has a first chamber for receiving anticoagulant used for priming the separator and purging the system of air prior to the initial draw cycle and a second chamber for receiving separated red blood cells. Because the entire volume of second chamber of the RCC reservoir may now receive separated red blood cells and no AC prime volume, a greater amount of whole blood may be processed in the first draw cycle, thus resulting in a greater total volume of Immunoglobulin G (IgG) being collected during the plasmapheresis procedure.
Claims6
A disposable fluid flow set for an apheresis system comprising:
- e) a separator;
- f) a first tubing segment connected to an outlet of the separator;
- g) a second tubing segment;
- and
- h) a reservoir comprising first and second internal chambers, each of said first and second chambers having a first port in fluid communication with the first tubing segment and a second port in fluid communication with the second tubing segment wherein the first internal chamber has an open upper end permitting fluid from the first internal chamber to spill over into the second internal chamber.
