    • The present invention is directed to an automatic injection device containing a pre-loaded charge of medicament for automatically self-administering the medicament upon actuation thereof. The automatic injection device includes a housing assembly having an interior chamber, an activation assembly and a needle assembly for dispensing a dissolved medicament to a user. A dry compartment for storing a predetermined dry charge of dry medicament is located within the interior chamber. A wet compartment for storing a predetermined amount of liquid injection solution is also located within the interior chamber. A separation assembly separates the dry compartment from the wet compartment. The separation assembly prevents transfer of the liquid injection solution from the wet compartment to the dry compartment prior to activation of the automatic injection device. One or more medicament support assemblies located within the dry compartment prevent the passage of undissolved medicament from the dry compartment.
    • 本发明涉及一种自动注射装置,其包含用于在致动药剂时自动给药的药物的预加载药物。 自动注射装置包括壳体组件,其具有内部腔室,激活组件和用于将溶解的药物分配给使用者的针组件。 用于存储预定的干药物的干燥室的干燥室位于内部室内。 用于存储预定量的液体注射溶液的湿室也位于内部室内。 分离组件将干燥室与湿室隔开。 分离组件防止在启动自动注射装置之前将液体注射溶液从湿室转移到干燥室。 位于干燥室内的一个或多个药物支持组件防止未溶解的药物从干燥室中通过。

    • An endoscopic instrument having an end effector assembly at a distal end, a flexible member connected to and extending from the end effector assembly and a handle assembly connected to the flexible member. The handle assembly includes a handle member, a nose member and a biasing element. The handle member has an inner bore. The hollow nose member has a shank configured for insertion into the inner bore. The biasing element is located within the inner bore and biases the flexible member relative to the handle member. The handle member may have a keyway or a projection configured for insertion into a keyway, and the nose member may have the other of the keyway or the projection. The flexible member has a retaining element affixed to its proximal end. The flexible member is inserted through the nose member with the retaining element located proximate the proximal end of the nose member and thereby retained between the handle member and the nose member. Relative axial movement between the handle member and the flexible member is minimized.
    • 一种内窥镜器械,其具有在远端的端部执行器组件,连接到端部执行器组件并且从端部执行器组件延伸的柔性构件以及连接到柔性构件的手柄组件。 手柄组件包括手柄构件,鼻构件和偏置元件。 手柄构件具有内孔。 中空的鼻部构件具有构造成用于插入到内孔中的柄。 偏置元件位于内孔内并相对于手柄构件偏置柔性构件。 手柄构件可以具有构造成用于插入键槽的键槽或突起,并且鼻构件可以具有键槽或突起中的另一个。 柔性构件具有固定到其近端的保持元件。 柔性构件通过鼻部构件插入,保持元件位于鼻部构件的近端附近,从而保持在把手构件和鼻部构件之间。 把手构件和柔性构件之间的相对轴向运动最小化。
