ABSTRACT:
The invention relates to disposable device for the continuous centrifugal separation of a physiological fluid. The inventive device comprises: a fixed axial element; a centrifugation chamber which is mounted such that it can rotate around the axis of said element; an inlet channel for the blood to be centrifuged, the dispensing port of which is located close to the base of the chamber; and an outlet passage for a separated constituent, the inlet port of which is located close to the other end of the chamber in a concentrated area of one of the separated constituents having the lowest mass density in order for same to be removed continuously. The above-mentioned chamber takes the form of a long tube. The fixed axial element comprises a second outlet passage for a second of the separated constituents, the inlet port of which is located close to the end of the chamber opposite the above-mentioned base in a concentrated area of said second separated constituent having the highest mass density in order for same to be removed continuously.
