Abstract
A method and system for collecting leukoreduced red blood cells employing a spinning membrane separator including a housing having an upper end region and a lower end region in an operating position with a red blood cell outlet in the upper end region of the housing and a whole blood inlet in the lower end region of the housing. The method and system provide for flowing additive solution into the whole blood inlet of the housing to prime the separator; flowing whole blood into the whole blood inlet of the housing; separating red blood cells from the whole blood; flowing separated red blood cells out of the red blood cell outlet of the housing; combining the separated red blood cells with additive solution; passing the separated red blood cells and additive solution combination through a leukoreduction filter; and collecting the filtered red blood cells and additive solution.
