摘要： A device for storage of a monomer liquid and a cement powder as starting components of a bone cement dough and for mixing the starting components, and for dispensing the mixed bone cement dough. The device includes a receptacle in which a monomer liquid container is arranged and a cartridge containing the cement powder. A feed plunger is arranged in the receptacle. A dispensing plunger is arranged between the monomer liquid container and the cement powder in the cartridge. The feed plunger can be punctured by a rod when motion of the feed plunger is blocked, whereby the dispensing plunger is propelled by propelling the rod further through the blocked and punctured feed plunger.
Also provided are an extrusion device for propelling a feed plunger and a dispensing plunger of a device for mixing of a bone cement dough, and a method for the production of a bone cement dough.

摘要： One aspect relates to a device for locally applying a medical fluid, including a flexibly deformable tube including a tube wall. The tube includes a plurality of openings in the tube wall, the plurality of openings connecting an inner line of the tube to the surroundings of the tube, and the tube being closed at a distal tube. A proximal tube end of the tube is liquid-permeably connectable to a container for the medical fluid such that the medical fluid from the container can be pushed through the proximal tube end of the tube into the inner line of the tube and can be pushed out through the plurality of openings into the surroundings of the tube. The device includes an outer sleeve for closing a subset of the plurality of openings, the outer sleeve being axially movably arranged around the tube, and being shorter than the tube such that the distal openings that are not part of the closed subset of the plurality of openings are exposed.

摘要： One aspect relates to a bone cement applicator having a cartridge with an interior, a cartridge head with a delivery opening, a mixing member which is movable in the interior with a mixing rod. A delivery plunger is arranged in the cartridge and is mounted in the interior and is pressable in the direction of the delivery opening. The delivery plunger rests with an outer cylindrical circumferential surface against an inner wall of the cartridge. A clamping element is arranged on the inner wall of the cartridge in the region of a back side of the interior. The clamping element projects out of the inner wall of the cartridge. The cylindrical circumferential surface of the delivery plunger is resiliently deformable by the clamping element in the direction of a central cylinder axis, such that the delivery plunger is clampable in place with the at least one clamping element on the back side of the cartridge.

摘要： A paste application device stores two starting components for mixing the starting components to form a paste and for application of the formed paste. The device comprises a two-component cartridge comprising two internal spaces, two feed plungers shiftable in the internal spaces and bordering the internal spaces on a first side of the two-component cartridge, and at least two dispensing openings by means of which the internal spaces are open on a second side of the two-component cartridge that is opposite from the first side. The device further comprises a hollow cylinder that is made of a plastic material and has one front face that is open and one front face that is partially closed, in which is situated an axially mobile plunger that has at least two pestles attached to it, wherein the at least two pestles are oriented in the direction of the open front face, wherein the open front face of the hollow cylinder is arranged to axially touch against the first side of the two-component cartridge, and a connector for a compressed gas cartridge extends through an opening in the pressure vessel wherein a flap valve can be used to regulate the volume flow of the starting components through the dispensing openings, and whereby the flap valve is operable by means of a rod assembly of the paste application device, whereby the rod assembly is supported with a clearance of at least 0.3 mm in at least one direction that is perpendicular to the main direction.
