Centrifugal processing blood and blood components in blood bags of formula annular processing.

摘要

A centrifuge (34) for processing blood components in a ring bag (4; 22) ring, the centrifuge (34) comprising a rotor (1) having an outer peripheral space (3) adapted for use with a bag ( 4; 22) ring and a central space (2) adapted for use with a secondary bag (33) which is connected, through a tube (21; 32), the bag (4; 22) ring, wherein the rotor for compressing at least partially emptying the ring bag (4; 22) of the ring by the addition of a hydraulic fluid in a chamber (5) under the ring bag (4; 22) of the ring, and wherein rotor also includes a shaft and a lid (6) that are rotatable therewith, also having the rotor supports (9, 10, 11) for positioning the bag (4; 22) ring in the outer space relative to the supports, wherein at least one of the supports comprises a groove (12) guide which can fit the tube (21; 32) connecting the bag (4; 22) ring to the secondary bag (33).
