    • An assembly for a drug delivery device is provided the assembly comprising a cartridge adapted and arranged to contain at least one dose of a drug, a bung being slidably arranged within the cartridge, a housing comprising a distal end and a proximal end, and a piston rod adapted and arranged for moving the bung in the distal direction with respect to the housing for dispensing a dose of the drug. The assembly further comprises a drive member and arranged for transferring movement to the piston rod for dispensing the dose, and an engagement member configured to mechanically cooperate with the piston rod and with the housing. The engagement member is moveable between a reset position, where the engagement member is allowed to rotate with respect to the housing, and an operating position, where the engagement member is rotationally locked with respect to the housing, wherein the assembly is configured such that the engagement member is rotated and simultaneously axially displaced during movement of the engagement member between the operating position and the reset position. The engagement member and the housing are threadedly engaged with one another, wherein at least one of the engagement member and the housing comprises a thread and the other one of the engagement member and the housing comprises an interaction. Furthermore, the use of an engagement member for a drug delivery device is described.
    • 提供了一种用于药物递送装置的组件,该组件包括适于并布置成容纳至少一剂药物的筒,可滑动地布置在药筒内的栓,包括远端和近端的壳体,以及活塞 杆适于并布置成相对于壳体在远端方向上移动栓,用于分配一定剂量的药物。 组件还包括驱动构件,其布置成用于将运动传递到活塞杆以分配剂量;以及接合构件,构造成与活塞杆和壳体机械配合。 接合构件可以在接合构件相对于壳体旋转的复位位置和操作位置之间移动,其中接合构件相对于壳体旋转地锁定,其中组件被构造成使得 接合构件在接合构件在操作位置和复位位置之间移动期间旋转并同时轴向移位。 接合构件和壳体彼此螺纹接合,其中接合构件和壳体中的至少一个包括螺纹,并且接合构件和壳体中的另一个包括相互作用。 此外,描述了使用用于药物递送装置的接合构件。

    • The invention provides a medical device having a valve mechanism which has an effective sealing, is simple and cost-saving to produce and at the same time provides an improved pressure control. Additionally, an improved biocompatibility can be provided. The medical device comprises a channel and at least one valve element. The channel comprises at least two openings, and the valve element comprises at least one sealing area. The valve element can be brought in a closed state, such that the sealing area of the valve element seals one of the openings of the channel and the valve element is at least in part flexible, such that the valve element can be brought into an open state by the pressure of a medium inside the channel and the medium can exit the channel between the valve element and the channel.
    • 本发明提供一种具有阀机构的医疗装置,其具有有效的密封,制造简单且成本节约,同时提供改进的压力控制。 另外,可以提供改善的生物相容性。 医疗装置包括通道和至少一个阀元件。 通道包括至少两个开口,并且阀元件包括至少一个密封区域。 阀元件可以处于关闭状态,使得密封通道的开口之一的阀元件的密封区域和阀元件至少部分地是柔性的,使得阀元件可以被打开 通过通道内的介质的压力,介质可以离开阀元件和通道之间的通道。
