A vacuum cementing system has at least one cement powder cartridge and a container-opening system. The container-opening system has at least one container for at least one liquid and/or at least one powder, an opening device, and an outlet opening for applying a negative pressure. When a negative pressure is being applied, the opening device is mobile relative to at least a part of the at least one container. The vacuum cementing system has a means for connecting the cement powder cartridge to the at least one container and utilizes necessary vacuum for automatically opening the at least one container.

A cartridge for squeezing-out a cartridge content, like a cement, or a medical cement, having a cylindrical hollow space bordered by a cartridge wall, a feed plunger arranged in the hollow space to be mobile along the cylinder axis of the hollow space and abutting the cartridge wall, and at least one snap-in means for locking the feed plunger in place at the cartridge wall, to a locking device arranged on the feed plunger and comprises at least a snap-in means which is accessible from outside when the feed plunger is locked. The invention also provides a cartridge system with a cartridge for squeezing out content and a method for dispensing such cartridge content, preferably a cement, through the use of a cartridge of said type.

A cartridge system for application of a flowable material has at least one cartridge having cartridge walls, one cartridge head, and one feed plunger opposite the cartridge head for expelling a cartridge content. The cartridge has at least one opening in the cartridge head or the cartridge wall that can be closed through a valve, wherein a rotatable valve is mounted in rotatable manner in a bracket on the cartridge head or cartridge heads or a shiftable valve is mounted in shiftable manner in a bracket on the cartridge. The valve has at least one passage through the valve that is connected to an outlet opening, the valve, in a closed position, closes in a sealed manner at least one opening of at least one cartridge, in particular all openings of all cartridges, the passage or passages is/are connected to the opening or openings in an open position of the valve such that a cartridge content can be squeezed from the cartridge or cartridges through the outlet opening. The valve can be transitioned from a closed position into an open position through a rotation of the valve or through shifting the valve, wherein the motion of the valve leads to a compressed gas cartridge that is or can be arranged in the cartridge system being opened through the compressed gas cartridge moving with respect to an opening device of the cartridge system.

Device and method for degassing and dispensing bone cement that can be used to produce a bone cement that is largely free of air inclusions. The device contains a dispensing tube (1) that comprises at least one section (2,3) that is permeable to gas, but impermeable to bone cement. The bone cement is being moved along the gas-permeable section which causes the gas present in the bone cement to flow through the gas-permeable material.

A mixing device, for a mixable material, has at least one cartridge and a closure piece. The cartridge contains a first component of the mixable material and has a cartridge head in which at least one air opening is arranged, and the closure piece is arranged on the cartridge head in such a way that the at least one air opening in the cartridge head can be closed and opened by the closure piece. The closure piece is mounted so as to be rotatable or slideable relative to the cartridge head, and a connection extends through the cartridge head or a cartridge wall into the interior of the cartridge and connects the interior of the cartridge to a container for a second component of the mixable material.

A cartridge system for mixing and applying a mixable material has a discharge opening and at least two cartridges which have interiors delimited in some areas by a cartridge head. A device regulates streams from the cartridges, is arranged on the cartridge head and has an outflow opening and conveying mechanisms for conveying the starting components to the outflow opening. Each conveying mechanism has a connection to an interior of a cartridge, which has a cartridge opening, and is arranged rotatably in the device. Volumetric flows of the components are defined by the angular velocities of the conveying mechanisms, and the conveying mechanisms are coupled to each other in such a way that the ratio of the angular velocities relative to each other is fixed, such that a defined mixing ratio can be generated at the outflow opening.
