    • By providing a pair of handle forming members and independently mounting the handle forming members to a desired product in a manner which enables the handle forming members to independently pivot while still cooperating to form a single gripping handle, a unique handle assembly is attained which is capable of being stowed in nested engagement with the product as an integral, co-extensive portion thereof. In the preferred embodiment, each handle forming member has a pair of arm portions mounted to the product with the arm portions being interleaved with each other to provide a compact stowed position, while being easily pivoted from the stowed position to an extended, handle forming position.
    • 通过提供一对手柄形成构件并且以能够使手柄形成构件独立地枢转同时仍然协作以形成单个抓握手柄的方式独立地将手柄形成构件安装到期望的产品,获得了独特的手柄组件,其能够 与产品嵌套接合,作为其完整的共同部分。 在优选实施例中,每个手柄形成构件具有安装到产品上的一对臂部分,其中臂部彼此交错以提供紧凑的收起位置,同时容易地从收起位置枢转到延伸的手柄形成位置 。

    • Methods and apparatus are set forth for preparing and delivering bone cement from a powdered polymer component and a liquid monomer component by simultaneously injecting the powdered and liquid components, stored in separate component chambers, into an evacuated mixing chamber under the effect of the vacuum; by uniformly mixing the components in the mixing chamber (to thoroughly wet the powder); and by delivering the cement formed by the polymerization process, as needed in an operative setting, utilizing a single ready to use device. The uniform mix is achieved by simultaneously subjecting the contents of the component chambers to the effects of the mixing chamber's vacuum via separate one way nozzles, interconnecting the component chambers to the mixing chamber, which cause the powder to be broadcast and liquid to be sprayed into the mixing chamber. The nozzles are designed and oriented in a predetermined manner (depending on the type and quantity of the constituent bone cement components being mixed), to cause the components to interact at a preselected distance within the mixing chamber, to assure uniform powder saturation and a thorough mix which yields a homogeneous reaction product.
    • 阐述了通过在真空下同时将存储在分离的组件室中的粉末和液体组分注入抽真空的混合室中来从粉末状聚合物组分和液体单体组分制备和输送骨水泥的方法和装置; 通过均匀地混合混合室中的组分(以彻底润湿粉末); 并且通过使用单个即用型装置,根据需要在操作设置中输送通过聚合过程形成的水泥。 均匀混合是通过使组分室的内容物经由单独的单向喷嘴同时对组分室的内容物进行混合,从而将组分室互连到混合室,从而使粉末被广播并且液体被喷射到 混合室。 喷嘴以预定的方式(取决于混合的组分骨水泥组分的类型和数量)被设计和取向,以使组分在混合室内以预选的距离相互作用,以确保均匀的粉末饱和度和彻底的 混合物产生均匀的反应产物。
