Abstract: Bone cement applicators and methods for application of a bone cement dough, the applicators and methods comprise a tubular cartridge with an internal space, a dispensing plunger for expelling the starting components through an opening of the cartridge opposite from the dispensing plunger, wherein the dispensing plunger is mobile in longitudinal direction in the internal space of the cartridge. The applicators and methods further comprise a hose, an application opening, a three-way valve operable from outside and arranged or arrangeable in the hose or on a side of the hose facing the cartridge, and a collecting container arranged on the three-way valve. The three-way valve is designed and arranged or arrangeable in the applicator such that it, being in a first position, provides a fluid connection between the application opening and the opening of the cartridge and closes a feed-through to the collecting container and, being in a second position, provides a fluid connection between the application opening and the collecting container and closes a passage to the opening of the cartridge.

Abstract: Storage and mixing systems and methods for pasty multicomponent polymethylmethacrylate bone cements, the systems and methods comprise a first tubular cartridge with a first cylindrical internal space containing a first starting component, a first dispensing plunger, a second tubular cartridge that is arranged within the first tubular cartridge. The external wall of the second cartridge touches against the internal wall of the first cartridge and is attached to the internal wall of the first cartridge, whereby the second cartridge contains a second starting component and has a second dispensing plunger arranged in it, whereby a pressing device with a clamping edge for compressing the second cartridge that can be propelled axially in the internal space of the first cartridge is arranged, as seen from the cartridge head, behind the first dispensing plunger and the second dispensing plunger. The pressing device can be propelled appropriately in the direction of the cartridge head such that the second cartridge is being progressively compressed axially during the motion of the pressing device such that, in the process, the first dispensing plunger and the second dispensing plunger are propelled in the direction of the cartridge head.
