摘要
(DE102016106261) A device mixes bone cement and stores parent components of the bone cement.  The device has a cartridge comprising an interior, that is closed on one side by a movable delivery plunger, a receptacle comprising side walls for receiving a monomer liquid container that are closed at least in some regions.  The receptacle has at least one deformable closed side wall, a screen and/or a filter arranged below the receptacle so that the contents of the opened monomer liquid container flow through the screen and/or the filter.  The device further has a connecting line through which the monomer liquid is to be routed into the interior of the cartridge, a hollow cylinder which is connected to the connecting line and which is connected to the receptacle by way of a fluid connection so that the hollow cylinder is arranged in a fluid line between the receptacle and the interior of the cartridge.  A pump plunger is arranged in the hollow cylinder, which is axially displaceable in the hollow cylinder, and an opening device, which is movably mounted against the deformable side wall of the receptacle.  The opening device extends into the hollow cylinder, wherein, by pressing the pump plunger into the hollow cylinder, the opening device is to be pressed against the deformable side wall of the receptacle so that the deformable side wall deforms such that a monomer liquid container located in the receptacle is to be opened by the pressure of the opening device.
