Apparatus for extracting a blood component contained in a system of bags

An apparatus for extracting at least one blood component contained in a primary bag of a system of bags, said system of bags further comprising at least one bag of solution containing an additive solution for said blood component and at least one collecting satellite bag configured to collect said blood component to which said additive solution has been added, said bags being connected to one another by tubes, said apparatus comprising:

• an extraction device configured to extract the blood component by compressing the primary bag, and
• a control device configured to transfer said extracted component or said extracted component and the additive solution, to the collecting satellite bag by the intermediary of tubes, further comprising:
• an agitation device configured to agitate the collecting satellite bag, and
• a drive system configured to control said extraction device, said control device and said agitation device, said system being designed to enable the uniform mixing of the extracted blood component and of the additive solution in said collecting satellite bag.
