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 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.

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.
摘要:
A surgical suture material with an antimicrobial surface is described, the surface exhibiting a coating containing a) at least one fatty acid, b) octenidine dichloride and/or dequalinium chloride and c) optionally oligomeric lactic acid esters. In addition, a process for coating surgical suture material is described which is characterized by the fact that the thread material is wetted with a homogeneous methanolic solution of octenidine dichloride and/or dequalinium chloride and subsequently the methanol is evaporated, a coating forming on the thread surface.
摘要:
A method and system for modeling the aortic valve in 4D image data, such as 4D CT and echocardiography, is disclosed. An initial estimate of a physiological aortic valve model is determined for at least one reference frame of a 4D image sequence based on anatomic features in the reference frame. The initial estimate is refined to generate a final estimate in the reference frame. A dynamic model of the aortic valve is then generated by estimating the physiological aortic valve model for each remaining frame of the 4D image sequence based on the final estimate in the reference frame. The aortic valve can be quantitatively evaluated using the dynamic model.
摘要:
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 local system for the liberation of an active principle is described which consists of spherical bodies which are composed of polymethyl methacrylate or polymethyl methacrylate co-methyl acrylate and, if necessary, zirconium dioxide and/or barium sulphate and a pharmaceutical active principle, which contains at least one hemostyptically effective compound stable at least up to 120° C., preferably a calcium salt. The local system for the liberation of an active principle is provided as medical product or drug.
摘要:
A dyed polymethyl methacrylate bone cement is described which is characterized by at least the surface of the polymer particles of the powder component being coated partially or completely with a mixture of one or several dyes and a hydrophobic, low molecular or oligomeric organic coupling agent, such a quantity of coupling agent being present that the polymer particles can be visually recognized as not having swollen.
摘要:
The invention relates to hardly soluble antiphlogistic salts and antiphlogistic-antibiotic pharmaceutical preparations and their use. The hardly water soluble antiphlogistic antibiotics salts have as their cationic component one of the antibiotics gentamicin, clindamycin, neomycin, streptomycin, tetracycline, doxicyline, oxytetracycline and rolitetracycline and as their anionic component one of the antiphlogistics ibuprofen, naproxen, indomethacin, dexamethasone-21-phosphate, dexamethasone-21-sulfate, triamcinolone-21-phosphate and triamcinolone-21-sulfate. The antiphlogistic antibiotics salts are used in pharmaceutical preparations as controlled-release antibiotic/antibiotics drugs. The invention describes antiphlogistic-antibiotic pharmaceutical preparations for which mixtures in the solid state of aggregation are used, which are composed of an easily water soluble salt of gentamicin, clindamycin, neomycin, streptomycin, tetracycline, doxicycline, oxytetracycline and/or rolitetracycline and at least one easily water soluble salt of ibuprofen, naproxen, indomethacin, dexamethasone-21-phosphate, dexamethasone-21-sulfate, triamcinolone-21-phosphate and/or triamcinolone-21-sulfate and at least one inorganic and/or organic pharmaceutical adjuvant and which are used as permanent or temporary implants in the form of tablets and/or molded bodies.
