Integrated automatic blood collection and processing unit

Centrifuges for use in the continuous separation of blood into components comprising the following parts: a housing (1430); a disc structure (930) rotatably mounted within the housing, forming a separation channel (990) comprising an inner wall (1117) and an outer wall (1118); a first inlet port (1220) adapted to introduce whole blood into the separation channel; a first outlet port (1040) adapted for removing concentrated red blood cells (1010) of the separation channel; and a second outlet port (1090) adapted for removing plasma from the separation channel substantially defining said separation channel a circle having a central point and a circle; wherein said disk structure is adapted for mechanical connection to a motor for rotating the disk structure about a central axis (1200) so that the circle defined by the separation channel is perpendicular to the central axis and the point center is substantially aligned with the central axis; and wherein the separation channel has a first portion in which the outer wall is at its maximum distance from the center or close to the same axis, the first part comprising a shaped portion pocket (1060) arranged to cause increasing the depth of a layer of red blood cells in the first outlet port (1120) located in the first part of the separation channel.
