  • Patent number: 9132573
    Abstract: A device stores and mixes a liquid and a solid component, in particular, the device mixes and stores a monomer liquid and a powder for producing bone cement. The device contains two chambers of which the first chamber contains the solid component and is separated from a second chamber that contains the liquid component by means of a separation that can be opened. A mixing facility that can be driven by means of a pressure difference is arranged in the first chamber. In the present storage and mixing system, a vacuum that is available in the operating theatre is used to mix a monomer liquid and a bone cement powder in a vacuum and to operate a mixing facility simultaneously. Moreover, the vacuum can also be used to open a separation between monomer liquid and mixing space and to transfer the monomer liquid into the mixing space.

  • Patent number: 9072834
    Abstract: A device releases a fluid active substance, the device has at least one hollow space containing the fluid active substance, whereby the device contains water and a reducing agent, which are or can be made to be in communication such that a chemical reaction of the water and the reducing agent produces a gas and the gas effectively communicates with the fluid active substance such that the gas pressure thus generated presses the fluid active substance out of at least one opening of the hollow space out of the device. A medical implant incorporates the device, and a method releases a fluid active substance from a hollow space of the medical implant, in which a gas is produced through a chemical reaction of liquid water and a reducing agent, and the resulting gas pressure is used to expel the fluid active substance out of at least one opening of the hollow space.
