The invention relates to a centrifuge provided with a blood bag system having
an upper and lower outlet for separation of blood constituents, containing a rotor
which can be driven in a rotative manner about a hub, wherein at least one conventional
whole blood bag equipped with an upper outlet and with a lower outlet can be positioned
vertically in this blood bag, while the whole blood bag can be arranged on the
rotor in such a way that one outlet of the whole blood bag is bent in a radial
direction, and the opposite outlet of the whole blood bag is bent in the other
radial direction, so that the entire whole blood bag and the outlets thereof adopt
an approximately Z- or S-shaped form in its functional position. In this case it
is preferred that the upper outlet of the whole blood bag lie radially toward the
interior and the lower outlet of the whole blood bag lie radially toward the exterior
of the whole blood bag. The whole blood bag is held in an insert, and the insert
is in its turn held by an approximately sector-shaped cartridge, wherein a plurality
of such cartridges is uniformly distributed by being arranged around the circumference
of the rotor. One advantage of the centrifuge is that conventional blood bags can
be used and recovery of individual blood constituents (plasma, erythrocytes, buffycoat)
can be achieved with a significantly higher degree of efficiency and functionality,
and with a high degree of purity.
