20110272434 | Cartridge Closure and Cartridge Having Said Closure - A cartridge system for application of a material has at least one cartridge having at least one cartridge has cartridge walls and one cartridge head each having at least one opening in each cartridge head, and a bracket that is arranged on the cartridge head or cartridge heads. A valve is mounted in rotatable manner in the bracket, wherein the valve has at least one passage through the valve that is connected to an outlet opening, wherein the valve, in a closed position, closes at least one opening of at least one cartridge, in particular all openings of all cartridges, in a sealed manner. The at least one passage is connected to the opening or openings in an open position of the valve such that the cartridge content can be squeezed out of the at least one cartridge through the outlet opening, and further wherein the valve can be transitioned from a closed position to an open position through a rotation of the valve. | 11-10-2011 |
20110272436 | Cartridge System and Dispensing Tube For Said Cartridge System - A cartridge system mixes and applies a mixing ware, such as, for example, a medical cement. The cartridge system has two cartridges that are arranged parallel to each other, and a mixing space having an outlet opening, wherein the cartridges each comprise at least one opening in the cartridge walls that connects the cartridges to the mixing space. The cartridges each comprise a feed plunger for expelling starting components of the mixing ware out of the cartridges through the openings, wherein a closure that can be shifted in the mixing space is arranged in the mixing space in a manner such that it closes the openings of the cartridges in a starting position and in that the openings to the mixing space are opened, at least in part, in a final position of the shiftable closure, wherein the shiftable closure can be shifted from a starting position to a final position. A dispensing tube for the cartridge system has, opposite from a dispensing tube tip of the dispensing tube, an extension with a diameter is smaller than an internal diameter of the mixing space, and which is designed to shift the shiftable closure during the insertion of the dispensing tube into the cartridge system head of the cartridge system such that the openings of the cartridges are open, at least in part. | 11-10-2011 |
20110272437 | Dispensing Device for Pasty Materials - A dispensing device for cartridges having a connection for supplying a pressurised gas, a base body, in which at least one passage and/or channel extends through which the pressurised gas can be guided to a first cartridge connector for connecting a cartridge. The first cartridge connector has a first opening towards the passage and/or the front channel such that a cartridge content can be expelled from the cartridge through application of the pressurised gas to a cartridge when the cartridge is arranged in the cartridge connector, wherein a second cartridge connector having a larger cross-section and a second opening is arranged at a front edge of the first cartridge connector The second cartridge connector is suitable for connecting a larger cartridge, and wherein the second opening of the second cartridge connector is sufficiently large to allow a cartridge to be connected to the first cartridge connector proceeding through the second opening. | 11-10-2011 |
20110272438 | Dispensing Device for Cartridges - A dispensing device for cartridges having a trigger grip for operating a valve of the dispensing device, a connection for supplying a pressurised gas, a cartridge connector for connecting a cartridge, and a base body, in which at least one passage extends through such that pressurised gas can be guided to the cartridge connector. The cartridge connector comprises an opening towards the passage such that the content can be expelled from the cartridge upon application of the pressurised gas to the floor of a cartridge when the cartridge is arranged in the cartridge connector, and wherein the passage can be closed and opened through the operated valve. The valve has a valve body that is arranged in the base body in a rotatable manner, wherein a motion of the trigger grip leads to a rotation of the valve body in the base body. The passage is arranged in or on the valve body such that the passage is closed in a first position of the valve body and the passage in or on the valve body guides the pressurised gas to the cartridge connector in a second position of the valve body. | 11-10-2011 |
20110287064 | ANTIBIOTIC COATING - An implant is provided having an antibiotic coating that is inexpensive and easy to manufacture. The antibiotic coating adheres well and in stable manner to the surface of the implant, can be degraded by the body without forming toxic products, prevents the crystallization of the antibiotics in the coating, and ensures a high immediate locally-effective antibiotic concentration at the implant site. A coating solution useful for making the implant and a method for the manufacture of the implant are also described. | 11-24-2011 |
20120006874 | Vial Breaker - The invention relates to a device for vial opening comprising an external container, in which a closed vial having a vial body and a vial head is arranged, and comprising a hollow space in the region of the vial head, whereby the hollow space comprises at least one opening and a connection to the vial, whereby the vial head, at least regions thereof, is arranged in the connection of the hollow space to the vial, and the walls of the external container comprise at least one deformable region or are altogether made of a deformable material, whereby tilting of the vial with respect to the connection is made feasible, and the diameter of the connection is adapted to the dimensions of the vial head in such a manner that the vial head can be fractured or broken off the vial body when the vial is being tilted with respect to the connection. | 01-12-2012 |
20120009327 | Method and Device for Coating of a Medical Implant - The invention relates to a method for coating of a medical implant that can be used to apply a calcium salt to the surface of a medical implant easily and without expensive coating equipment and little expenditure of time. | 01-12-2012 |
