Blood processing systems and methods that alternate flow of blood component and additive solution through an in-line leukofilter
First Claim
1. A blood processing system comprisinga source of blood cells,a blood cell storage container,a source of an additive solution for blood cells,a blood component collection flow channel communicating with the blood cell storage container and including an in-line filter to remove leukocytes from blood cells before entering the blood cell storage container,a pumping mechanism communicating with the blood component collection flow channel and operable in different modes, anda controller is programmed to operate the pumping mechanism in such different modes, including a first mode to convey blood cells from the blood cell source into the blood component collection flow channel and a second mode for conveying additive solution from the additive solution source directly into the blood component collection flow channel, the controller is programmed to alternate the pumping mechanism between the first and second modes.

Abstract
Blood processing systems and methods convey blood cells from a blood cell source into a blood component collection flow channel that includes a blood cell storage container and an in-line filter to remove leukocytes from blood cells before entering the blood cell storage container. The systems and methods also convey additive solution from an additive solution source into the blood component collection flow channel. The systems and methods alternate the conveyance of blood cells through the filter with the conveyance of additive solution through the filter.
