ABSTRACT:
The claimed invention refers to a centrifuge intended for processing blood and blood components and with its function based on the effective utilisation of ring type blood processing bags with associated secondary bags and other accessories. The most outstanding feature of the centrifuge, in accordance with the claimed invention, is that its rotor, at the same intended height of the ring bag (22) inner periphery, shows at least three supports (9–11) arranged along this periphery and intended to locate the ring bag's inner strengthened periphery edge on guide holes at the same time as the centrifuge and its rotor is equipped with a joint rotating inner lid (6) which includes a clamp function (7) that clamps ring bag (22) securely along and between supports (9–11). Furthermore, in the invention these supports (9–11) have, on the one hand, built-in valve functions for communication between the ring bag and the respective secondary bags can be actively controlled and, on the other hand, sterile welding functions for communication between ring bag (22) and the respective secondary bags when interruption and blocking is required.
