Abstract

Processing chamber for use with apheresis devices are described herein. An example centrifugal processing chamber includes first and second lateral walls spaced at a distance from one another. Additionally, the example centrifugal processing chamber includes a channel at least partially defined by the first and second lateral walls. Further, the centrifugal processing chamber includes an inlet fluidly coupled to the channel to convey blood to the channel. Further still, the centrifugal processing chamber includes a first outlet fluidly coupled to the channel having a first opening adjacent the first lateral wall. The first outlet is to convey separated plasma from the channel. Additionally, the centrifugal processing chamber includes a second fluid outlet fluidly coupled to the channel having a second opening adjacent the second lateral wall. The second outlet is to convey separated red blood cells from the channel. Additionally, the processing chamber includes a barrier formed along the second lateral wall to intercept platelets. The first and second lateral walls are spaced such that the distance between the first and second lateral walls enables at least one therapeutic unit of single dose platelets to pool adjacent the barrier without spilling into the first outlet or the second outlet.
