| 摘要 |
The invention relates to a device for the mixing of polymethylmethacrylate bone cement and for storing the starting components of the bone cement, in particular a monomer liquid and a cement powder as starting components of the bone cement, whereby the device comprises a cartridge (1) having an internal space (24) for mixing the bone cement, which is closed on one side by a mobile dispensing plunger (2); a monomer container (46) for a monomer liquid and/or a connector (20) for attachment of a monomer container (46) for a monomer liquid, such that the monomer container (46) can be opened appropriately in the device such that the monomer liquid flows from the monomer container (46) into the device; a connecting conduit (38) through which the monomer liquid can be guided into the internal space (24) of the cartridge (1); whereby a hollow cylinder (12) is connected to the connecting conduit (38) and the hollow cylinder (12) is arranged between the monomer container (46) or the connector for the monomer container (46) and the internal space (24) of the cartridge (1), whereby a pumping plunger (14) that can be shifted axially in the hollow cylinder (12) is arranged in the hollow cylinder (12), whereby the monomer liquid can flow from the opened monomer container (46) into the hollow cylinder (12) and the connecting conduit (38) appropriately connects the hollow cylinder (12) to the internal space (24) of the cartridge (1), such that the pumping plunger (14) can be used to push monomer liquid from the hollow cylinder (12) through the connecting conduit (38) into the internal space (24) of the cartridge (1) by actuating the pumping plunger (14). The invention also relates to a method for the mixing of polymethylmethacrylate bone cement. |
