A dual clutch includes a first clutch area with a housing arrangement connected to an abutment plate; a first pressure plate arrangement; and a force-exerting arrangement, which is supported against the housing arrangement and the pressure plate arrangement, and which can press the pressure plate arrangement toward the abutment plate. A second clutch area includes second pressure plate arrangement and a force-transmitting arrangement, which extends axially across the abutment plate and can exert force on the second pressure plate arrangement. The housing arrangement and the abutment plate are connected to each other by the production of a press fit, and a first force-transmitting element and a second force-transmitting element of the force-transmitting arrangement are also connected to each other by the production of a press fit.

A one-piece dispensing device for the contamination-free administration of medicaments (cytostatica) is particularly suitable for use in ambulant treatment. The invention provides a connector for connecting medicament (cytostatica) containers to instruments by which the medicaments are administered. The connector is designed to prevent, without a complex apparatus, contamination of the surroundings during connection of the container and until its disposal. The dispensing device has at least one coupling member to create a non-releasable connection with a medicaments container. The coupling member has an insertion pin and barbed surfaces to accommodate the medicaments container. The coupling member is non-releasably connected via a tube to a flexible container which is to be filled with gas. The flexible container is non-releasably connected to a further tube outlet and a mechanically actuated stop valve is incorporated in each of the connecting tubes.

A method for coating at least regions of a medical implant includes providing a medical implant having a surface to be coated, and immersing the surface of the medical implant into a liquid including at least one pharmaceutically active substance, whereby the liquid is transferred to the surface of the medical implant due to the immersing. The method also includes pulling the surface of the medical implant out of the liquid, whereby part of the liquid remains adhering to the surface of the medical implant.

摘要:
A discharge device discharges the content of a container by applying a compressed gas. The device has a housing, at least one compressed gas container, an operating device for setting a gas flow from the compressed gas container and an opening means for opening the compressed gas container. The opening means is movable in relation to the compressed gas container, and the device has a holder for securing the container on the device. The holder is in operative connection with the opening means in such a way that securing the container on the holder brings about a movement of the opening means in relation to the compressed gas container that opens the compressed gas container.
摘要:
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 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.

A device is provided with which it is possible to produce poly(methyl methacrylate) bone-cement paste, which is degassed to the greatest extent possible, while avoiding large-volume mixing containers and large cement volumes contained therein. The device includes a tubular hollow body (10) having a first opening (30) on the input side and a second opening (20) on the output side, at least one rotatably-mounted shaft (40) arranged in the axial direction in the tubular hollow body (10), thread turns (50) arranged axially along the outer side of the shaft (40), wherein the shaft (40) has at least one section with thread turns (50) whose pitch decreases in the direction of the second opening (20), at least one stirring blade (60) arranged on the shaft (40), and rigid mixing elements (70) arranged on the inner side of the tubular hollow body (10).
摘要:
A bone cement system (100) is provided having a mixing facility (10) for mixing and dispensing of bone cement, a reservoir container (112) for a monomer, and a conveyor (122). The mixing facility (10) has a mixing cylinder (20), which stores a bone cement powder. The monomer can be conveyed from the reservoir container (112) into the mixing cylinder (20) by the conveyor (122). A sieve element is (4) is arranged between the reservoir container (112) and the mixing facility (10), in order to prevent ingress of the bone cement powder from the mixing cylinder (20) into the conveyor (122). The mixing device (10) included a dispensing opening (23) for dispensing a bone cement mixed from the bone cement powder and the monomer. The dispensing opening (23) includes a shield (1) having at least one through-opening (2). The ratio of the area of the through-opening (2) to the area of the sieve element (4) is at least 1 to 3, and the distance between the shield (1) and the sieve element (4) is at least 1 mm.
摘要:
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.
