The invention relates to a device for storage of a monomer liquid (4) and acement powder (5) asstarting components of a bone cement dough (54) and for mixing of the bonecement dough (54)from the starting components, and for dispensing the mixed bone cement dough(54), the devicecomprising a tube-shaped container that forms, on its rear side, a receptacle(2) with a cylindricalinternal space, in which a monomer liquid container (3) is arranged, wherebythe monomer liquidcontainer (3) contains the monomer liquid (4), and the container forms, on itsfront side, a cartridge(1) with a cylindrical internal space that contains the cement powder (5),whereby a feed plunger(6) which is movable in a longitudinal direction of the receptacle (2) andwhich is accessible froma rear side of the receptacle (2) is arranged in the internal space of thereceptacle (2), whereby adispensing plunger (7) which is movable in longitudinal direction in theinternal space of thecartridge (1) is arranged between the monomer liquid container (3) and thecement powder (5) inthe internal space of the cartridge (1), whereby the internal space of thereceptacle (2) and theinternal space of the cartridge (1) are connected to each other through aconnection (14) that ispermeable to the monomer liquid (4) and gases, but is impermeable to thecement powder (5),and whereby the feed plunger (6) is puncturable, from the rear side, by a rod,when a motion ofthe feed plunger (6) in the direction of the front side of the container isblocked, whereby thedispensing plunger (7) is propellable by propelling the rod further throughthe blocked andpunctured feed plunger (6) in the direction of a front side of the cartridge(1).The invention also relates to an extrusion device for propelling a feedplunger (6) and a dispensingplunger (7) of a device for mixing of a bone cement dough as well as to amethod for the productionof a bone cement dough.
