摘要： One embodiment relates to a device for the production of a bone cement dough from a monomer liquid and a cement powder comprising a cartridge with an internal space; a cartridge head with a dispensing opening; a conveying plunger that is arranged in the internal space of the cartridge and is supported in the internal space of the cartridge such that it is pushable in the direction of the dispensing opening; a dispensing plunger between the dispensing opening and the conveying plunger that is supported in the internal space of the cartridge such that it is pushable in the direction of the dispensing opening; a first hollow space, in which the cement powder is arranged; a second hollow space that is bordered by the dispensing plunger and the conveying plunger; a fluid opening that is arranged in the conveying plunger; a feedthrough that connects the first hollow space and the second hollow space to each other, and a closure means that is arranged on a rear side of the dispensing plunger. The closure means projects away from the dispensing plunger and is situated at a distance from the fluid opening. The fluid opening is closable with the closure means. The closure means is mobile in the closed fluid opening such that the fluid opening stays closed, while the conveying plunger is pushable further in the direction of the dispensing plunger.
