Disposable device for the continuous centrifugal separation of a physiological fluid

A disposable device for the continuous centrifugal separation of a physiological liquid, particularly blood, comprising a fixed axial input and output element about the axis of which a plastic centrifuging chamber is mounted such that it can rotate, an inlet pipe for the blood that is to be spun in the centrifuge passing longitudinally through said axial inlet and outlet element, its delivery opening lying near the bottom of said centrifuging chamber, an outlet passage for at least one separated constituent, its inlet opening lying near the opposite end of said chamber to said bottom and in a region where at least one of the separated constituents that has the lowest specific mass becomes concentrated so that it can be drawn off continuously, this passage passing through a longitudinal portion of said fixed axial inlet and outlet element, a rotary seal between said fixed axial element and said centrifuging chamber, wherein this centrifuging chamber is of elongate tubular shape and its wall forms a flow and separation surface for the liquid that is to be separated, said fixed axial inlet and outlet element comprising a second outlet passage for at least a second of the separated constituents, its inlet opening lying near the opposite end of said chamber to said bottom and in a region of said flow where said second separated constituent that has the highest specific mass becomes concentrated so that it can be drawn off continuously.
