A method and a device for preparation of bone cement. The constituent components of bone cement are mixed under vacuum in a closed mixing chamber, which has a vacuum connection (4), a moveable wall section (2), a device arranged to maintain the moveable wall section (2) in its initial position during the mixing process, an extrusion opening located opposite to the moveable wall section (2) and a device (9) arranged to openably seal the extrusion opening. The extrusion is performed by the moveable wall section (2) being brought to move towards the extrusion opening, by applying a force against the moveable wall section (2) using an extrusion tool (12). The moveable wall section (2) is set free after mixing is finished and thereafter forced towards the extrusion opening for compression of bone cement while the extrusion opening is sealed by the sealing device (9). |
