Abstract
One aspect is a method for producing a bone cement from monomer liquid and cement powder using a depressurization device. The method is performed using a device comprising a cartridge having a drive piston, and a central piston being permeable to gases and the monomer liquid and impermeable to the cement powder and being arranged between the drive piston and a cartridge head. The method comprising the steps of expelling residual gases into the surroundings of the device by means of the movement of the drive piston; displacing gases between the powder particles with the inflowing monomer liquid; and depressurizing a cavity of the cartridge, by partially removing the contained monomer liquid. The invention also relates to such a device for mixing a bone cement, with a depressurization device.
