Abstract
A device for storage of a monomer liquid and a cement powder as starting components of a bone cement dough and for mixing the starting components, and for dispensing the mixed bone cement dough. The device includes a receptacle in which a monomer liquid container is arranged and a cartridge containing the cement powder. A feed plunger is arranged in the receptacle. A dispensing plunger is arranged between the monomer liquid container and the cement powder in the cartridge. The feed plunger can be punctured by a rod when motion of the feed plunger is blocked, whereby the dispensing plunger is propelled by propelling the rod further through the blocked and punctured feed plunger.Also provided are an extrusion device for propelling a feed plunger and a dispensing plunger of a device for mixing of a bone cement dough, and a method for the production of a bone cement dough.
