Abstract (en)

[origin: EP1186346A1] A channel (10) following a concave curve relative to the rotational axis (2) of the enclosure (1) has a blood supply opening (7) and two openings (8,9) for the evacuation of the separated components. Rotation of the enclosure applies radial forces to the blood to be separated in order to sediment solid particles against the channel outer side wall. This side wall has several adjacent recesses following one another in the blood flow direction (F). The wall connecting the bottom of each recess at its upstream end has an angular length determined in relation to the enclosure rotational axis of the and the distance between this wall and the rotational axis decreases progressively from the recess bottom to its upstream end.
