    • The present invention is generally directed to an injection device for setting and dispensing a number of user variable doses of a medicament and a method of assembling same. The injection device comprises a housing (10) having a longitudinal axis (I), a dose setting member (60; 80) rotatable relative to the housing (10) during dose setting, and a torsion spring (90) which is strained during dose setting and which is attached with its first end to the housing (10) and with its second end (91) to the dose setting member (60; 80). The dose setting member (60; 80) comprises a guide or groove(68) with side walls having the form of a ring segment for receiving the second end (91) of the spring (90) and a non-return feature (69a, 69c) for anchoring the second end (91) of the spring (90) within the guide or groove (68) and/or an end feature (69b, 69d) located within the guide or groove(68) such that it pushes the second end (91) of the spring into contact with a side wall of the guide or groove (68).
    • 本发明一般涉及用于设置和分配多个用户可变剂量的药物的注射装置及其组装方法。 注射装置包括具有纵向轴线(I)的壳体(10),在剂量设定期间相对于壳体(10)可旋转的剂量设定构件(60; 80)和在剂量期间应变的扭转弹簧(90) 并且其第一端附接到壳体(10)并且其第二端(91)附接到剂量设定构件(60; 80)。 剂量设定构件(60; 80)包括导向件(或凹槽)(68),侧壁具有用于容纳弹簧(90)的第二端(91)的环形段的形式,以及不返回特征(69a ,69c),用于将弹簧(90)的第二端(91)锚定在位于引导件或槽(68)内的引导件或凹槽(68)和/或端部特征(69b,69d)内,使得其推动 弹簧的第二端(91)与引导件或凹槽(68)的侧壁接触。

    • The present invention is generally directed to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The device comprises a housing (10) having a tubular portion (12) with an inner thread, a piston rod (30) having a threaded portion (31) and a distal end, and a bearing (140) having a distal face and a proximal face. The bearing (140) comprises a retaining stem (142) protruding from the proximal face. The piston rod (30) comprises a distal portion having an outer diameter which is smaller than the inner diameter of the inner thread of the tubular portion (12) and comprising at its distal end at least one retaining clip (33, 33′) engaging the retaining stem (142). The axial length of the tubular portion (12) is smaller than or equal to the axial distance between the proximal face of the bearing disc (141) and the distal end of the threaded portion (31) of the piston rod (30). During manufacturing of the device, the retaining clip (33, 33′) engages the retaining stem (142) prior to the inner thread of the tubular portion (12) engages with the threaded portion (31) of the piston rod (30).
    • 本发明是针对一种药物递送装置,用于选择和分配多个用户可变剂量的药物中的基因的反弹。 该装置包括具有与所述内螺纹的管状部分(12)和具有远端面和一螺纹部分(31)和一个远端,以及一个轴承(140)的壳体(10),活塞杆(30) 近端面。 所述轴承(140)包括一个保持杆(142)从近端面突出。 活塞杆(30)包括具有外径的远侧部分的所有比所述管状部分(12)的内螺纹的内径小,并在其远端包括至少一个保持夹(33,33“)接合 所述保持杆(142)。 筒状部(12)的轴向长度小于或等于所述支承盘(141)和所述活塞杆(30)的螺纹部分(31)的远端的近端面之间的轴向距离。 在制造过程中该装置的,所述保持夹(33,33“)接合所述保持杆(142)之前,所述管状部(12)与活塞杆(30)的螺纹部分(31)接合的内螺纹。
