Device for providing bone cement dough

A device for providing a bone cement dough from two starting components, comprising:

• a hollow cylindrical cartridge with an interior space, wherein
• a bone cement powder as a first starting component is stored in a proximal part of the interior space, and at least two pouches containing a monomer liquid as a second starting component are stored in a distal part of the interior space,
• wherein a dispensing plunger axially movable in the interior space is arranged between the bone cement powder and the at least two pouches, and a delivery plunger axially movable in the interior space is arranged on a side of the at least two pouches that is axially opposite the dispensing plunger,
• wherein the proximal part and the distal part of the interior space are fluidically connected to one another via a conduit means,
• wherein
• the dispensing plunger can be subdivided into four equal-sized quadrants on a distal side of the dispensing plunger facing toward the at least two pouches,
• wherein each of the four quadrants has at least one opening means so that, by advancing the delivery plunger in a direction of the dispensing plunger, the at least two pouches are to be opened by the opening means and the monomer liquid is to be delivered into the bone cement powder.
