摘要： A method and apparatus for mixing bone cement (96) which produces bone cement (96) essentially free of entrained air. The apparatus includes a cartridge (30) having two telescoping cylinders (44,46). The outer cylinder (44) receives a cap (32) thereon which hermetically seals the cartridge (30). The cap (32) includes an outlet port (62) in which a break-away agitator (34) is installed and a port (60) for connection of a vacuum pump (24). In use, a desired vacuum pressure is drawn on the cartridge (30) and the inner cylinder (46) is allowed to be drawn into the outer cylinder (44) while the vacuum is being drawn, whereupon the inner cylinder (46) automatically stops moving relative to the outer cylinder (44) when the desired vacuum pressure is reached. Mixing of the bone cement (96) is then performed under the partial vacuum thereby created. The agitator paddles (74) provide a scraping action against both inner cylinder walls of the telescoping cylinders (44,46) thereby improving mixing. After mixing, the agitator (34) is broken away, an appropriate nozzle (36) is attached to the cartridge (30) and the cartridge (30) is inserted into a cement gun. The leading portion of the bone cement (96) develops a convex profile when axially advanced through the cartridge (30) and the piston plug (48) includes a tapered protrusion (92) which generally corresponds to the profile of the bone cement (96). The cap (32) and paddles (74) are also shaped correspondingly to the convex profile developed by the bone cement (96), resulting in substantially all of the bone cement (96) being squeezed from the cartridge (30). An air escape passage (66) is also provided to vent air contained within an annular gap between the agitator shaft (70) and the cap (32) upon initial expulsion of bone cement (96), resulting in the bone cement (96) expelled from the cartridge (30) being essentially free from entrained air.
摘要翻译：一种用于混合骨水泥（96）的方法和设备，该骨水泥（96）产生基本上没有夹带空气的骨水泥（96）。该设备包括具有两个伸缩缸（44,46）的盒（30）。外筒（44）在其上接收密封盒（30）的盖（32）。盖（32）包括其中安装有脱离式搅拌器（34）的出口端口（62）和用于连接真空泵（24）的端口（60）。在使用中，在筒（30）上抽吸期望的真空压力，并且在抽真空时允许内筒（46）抽入外筒（44），随后内筒（46）自动停止当达到期望的真空压力时相对于外筒（44）移动。然后在由此产生的部分真空下进行骨水泥（96）的混合。搅拌桨（74）对伸缩缸（44,46）的内筒壁提供刮擦作用，从而改善混合。在混合之后，搅拌器（34）被打破，合适的喷嘴（36）被附接到筒（30），并且筒（30）被插入到水泥枪中。当轴向前进通过药筒（30）并且活塞塞（48）包括通常对应于骨水泥（96）的轮廓的锥形突起（92）时，骨水泥96的引导部分形成凸起轮廓，。帽（32）和桨（74）也与由骨水泥（96）产生的凸起轮廓相对应地成形，导致基本上全部骨水泥（96）从筒（30）挤出。还提供排气通道（66），用于在骨水泥（96）初始排出时排出容纳在搅动器轴（70）和盖（32）之间的环形间隙内的空气，导致骨水泥（96）排出从盒（30）中基本上没有夹带的空气。

摘要： An apparatus (5) for mixing bone cement in a vacuum includes a container (10) for mixing first (45) and second components of a bone cement in a vacuum, the container having a sealed body (40) defining an interior space and a selected quantity of the first component (45) disposed in the interior space. The container (10) is provided with an injection port (80) for admitting the second component into the interior space vacuum source (15). A mixing paddle (120) is disposed in the interior space and connected to a handle (125) therefor extending out of the container (10). A plurality of indirect pathways (105,115) extend between the interior space and the exhaust port (75) which permit gas to pass therethrough out of the interior space, but prevent the bone cement first (45) and second components from passing therethrough.

摘要： A disposable telescoping mixing cartridge for mixing and delivering a quantity of bone cement. The cartridge cap includes a break-away agitator which opens an outlet port for the flow of cement. Therefore, the single opening serves as both an outlet port for the cement and the opening through which the agitator is reciprocated.

摘要： An electronic mouse (100) controlled substantially by finger movement. The translation of the mouse (100) can be controlled by the index finger placed over a primary selection button (125). Means for facilitating translation of the mouse are provided for in the primary selection button (125). Means for facilitating translation include, but are not limited to, concave depressions, protrusions and surface texture with a high coefficient of friction.

摘要： A two-component bone cement mixing system comprises a cartridge mixer having an interior volume containing a first predetermined quantity of a solid bone cement component under vacuum pressure; an ampoule containing a second predetermined quantity of a liquid bone cement component; a fluid transfer element for fluidically connecting the cartridge mixer and the ampoule for transfer of the liquid bone cement component to the cartridge mixer; and a plug element, receivable within the ampoule, for automatically hermetically sealing the fluid transfer element against passage of a material therethrough upon completion of the transfer of the second predetermined quantity of the liquid bone cement component into the cartridge mixer. The two-component bone cement mixing system allows in vacuo mixing of liquid monomeric and solid polymeric bone cement components without air being incorporated into the mixture and insures the prevention of air passage into the cartridge mixer during and/or after monomer transfer.
