Systems and methods separate pump the blood cells through an in-line leukofilter to a blood cell storage container. The leukofilter has a filtration medium enclosed within a flexile housing. The systems and methods can employ a fixture to restrain expansion of the flexible filter housing during operation of the pump.

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.

A blood processing assembly comprises a frame rotatable about a rotational axis and a blood processing chamber carried by the frame for rotation about the rotational axis. An umbilicus has one end coupled to the blood processing chamber along the rotational axis and an opposite end held in a non-rotating position along the rotational axis. A mid region of the umbilicus extends, at least in part, outside the rotational axis. The frame carries at least one support channel, which is sized and configured to engage the mid region of the umbilicus. The support channel includes a side edge that is sized and configured to self-load the mid region of the umbilicus into the support channel in response to rotation of the frame in a designated direction.

Systems and methods separate blood cells from whole blood and pump the separated blood cells through an in-line leukofilter to a blood cell storage container. The leukofilter has a filtration medium enclosed within a flexile housing. The systems and methods employ a fixture to restrain expansion of the flexible filter housing during operation of the pump. The fixture has a bracket to enable its releasable attachment to the blood processing device employed to carry out the separation process.
