摘要： One aspect relates to a device for mixing two liquids including a tube having an open end, a main line connected to the tube in a liquid-permeable manner, a rubber-elastic body delimiting a line wall of the main line, at least one secondary line in the rubber-elastic body, wherein the at least one secondary line extends from at least one secondary opening up to the main line and opens via at least one mouth into the main line, a main connection for introducing a first liquid into the main line, at least one feed line for introducing a second liquid into the at least one secondary line, which is connected to the at least one secondary opening in a liquid-permeable manner. The at least one secondary line is closed in the rubber-elastic body without the action of a force and is hydraulically openable by a pressure being exerted on a second liquid fed to the at least one secondary line by an elastic deformation of the at least one rubber-elastic body. The open at least one secondary line closes without a pressure being exerted on the supplied second liquid by the restoring force of the elastically deformed rubber-elastic body.

摘要： One aspect relates to an engine including a working system, having a first piston-cylinder system, comprising a working piston and a working cylinder. The working piston divides the working cylinder into a first working cylinder portion and a second working cylinder portion, a valve system, having a first valve connection and a valve element. The valve system and the working system are connected in a gas conducting manner, the first valve connection can be connected to a negative pressure source, and the valve element is movably arranged in the valve system such that, in a first valve position, the valve element connects the first valve connection to the first working cylinder portion, and, in a second valve position, connects the first valve connection to the second working cylinder portion in a gas conducting manner. One aspect furthermore relates to a medical device having the engine and a method for treating a mammal.

摘要： A femoral hip joint spacer including a prosthesis body having a ball head with a sliding surface, a neck, a collar and a stem. A fastening area is arranged on the stem. The femoral hip joint spacer further has a first connector for feeding a medical irrigation liquid into the body, a second connector for draining the irrigation liquid from the body, and an irrigation liquid inlet opening. The first connector is connected in a liquid-conveying manner to the irrigation liquid inlet opening and an irrigation liquid outlet opening. The second connector is connected in a liquid-conveying manner to the irrigation liquid outlet opening, an irrigation liquid discharge opening and an irrigation liquid intake opening. The irrigation liquid discharge opening is connected inside the body to the irrigation liquid inlet opening and the irrigation liquid intake opening is connected inside the body to the irrigation liquid outlet opening.

摘要： One aspect relates to a device for the production of a bone cement dough from a monomer liquid and a cement powder comprising a cartridge with an internal space; a cartridge head with a dispensing opening; a conveying plunger that is supported in the internal space of the cartridge such that it is pushable in the direction of the dispensing opening; a dispensing plunger between the dispensing opening and the conveying plunger that is supported in the internal space of the cartridge such that it is pushable in the direction of the dispensing opening; a first hollow space, in which the cement powder is arranged; a second hollow space that is bordered by the dispensing plunger and the conveying plunger; a rear-side part of the internal space of the cartridge; and a conducting means that connects the second hollow space to the rear-side part of the internal space of the cartridge such as to bypass the conveying plunger and be permeable to the monomer liquid. The conducting means can be closed by the conveying plunger with respect to the second hollow space by shifting the conveying plunger in the direction of the dispensing plunger, and a feedthrough in the dispensing plunger that connects the first hollow space and the second hollow space such as to be permeable to the monomer liquid.

摘要： Bone cement applicators and methods for application of a bone cement dough, the applicators and methods comprise a tubular cartridge with an internal space, a dispensing plunger for expelling the starting components through an opening of the cartridge opposite from the dispensing plunger, wherein the dispensing plunger is mobile in longitudinal direction in the internal space of the cartridge. The applicators and methods further comprise a hose, an application opening, a three-way valve operable from outside and arranged or arrangeable in the hose or on a side of the hose facing the cartridge, and a collecting container arranged on the three-way valve. The three-way valve is designed and arranged or arrangeable in the applicator such that it, being in a first position, provides a fluid connection between the application opening and the opening of the cartridge and closes a feed-through to the collecting container and, being in a second position, provides a fluid connection between the application opening and the collecting container and closes a passage to the opening of the cartridge.

摘要： Storage and mixing systems for pasty two-component polymethyl methacrylate bone cements comprise a tubular cartridge having a cylindrical inner chamber, a cartridge head, which closes one end of the tubular cartridge at the front side, a partition that is disposed axially in the cylindrical inner chamber of the cartridge. The partition divides the cylindrical inner chamber of the cartridge bounded by the cartridge head into two cavities that are spatially separated from one another, wherein a first pasty cement component is present in the first cavity and a second pasty cement component is present in the separate second cavity. The systems further comprising two dispensing plungers axially displaceable in the two cavities of the cartridge, wherein the dispensing plungers close the two cavities on the back side of the cavities situated opposite the cartridge head, a bending device for deforming the partition, wherein the bending device is axially movable in the cartridge and is disposed, or is to be disposed, behind the dispensing plungers, as seen from the cartridge head, wherein the bending device has a deflection surface that is inclined with respect to the axis of the cartridge and pushes the partition laterally in the direction of the inside wall of the cartridge when the bending device is pushed into the cartridge.
