ABSTRACT:
An apparatus for separating a blood component, e.g., fibrin monomer, from blood or plasma comprises a container (110) with a reaction chamber for receiving the plasma, where said reaction chamber is defined by an outer wall and comprises means for supplying said reaction chamber with an agent for converting the fibrinogen content of the plasma into a non-cross-linked fibrin polymer. The apparatus comprises furthermore a device for centrifuging the reaction chamber with the plasma and said agent to a degree sufficient for separating the non-cross-linked fibrin polymer from the plasma, for depositing said polymer on the outer wall of the reaction chamber, and for expelling the remaining plasma from the reaction chamber. The container (110) comprises means for supplying the reaction chamber with a solvent for dissolving said non-cross-linked fibrin polymer. The apparatus comprises furthermore a measuring device (130) for measuring the amount of the deposit of the non-cross-linked fibrin polymer on the outer wall of the container (110), as well as a control unit (131) for controlling the addition of solvent in response to said amount of polymer.
