Bone cement mixing system with inter-chamber valve

Abstract

The invention relates to a device for producing a bone cement, comprising a storage container for receiving a sealed vessel containing a monomer liquid, and a cartridge for mixing bone cement, wherein the cartridge comprises a first chamber for receiving monomer liquid from the storage container and a second chamber for receiving a bone cement powder, and wherein the cartridge further comprises a valve which fluidically connects the first chamber to the second chamber, wherein the device is designed and configured, in a first step, to release a monomer liquid from a sealed vessel within the storage container and to deliver it to the first chamber of the cartridge, in a second step, to keep the monomer liquid within the first chamber, wherein contact of the monomer liquid with the second chamber of the cartridge is avoided, and in a third step, to deliver the monomer liquid from the first chamber of the cartridge into the second chamber of the cartridge.
