    • The invention relates to a compression connection means for an auto-injector (A), wherein the compression connection means adapted to attach a front-end device of the auto-injector (A) to a back-end device of the auto-injector (A) comprises of an annular mounting sleeve that is axially displaceable parallel to a longitudinal axis (X) between a locked position (L) and an unlocked position, a mounting sleeve spring biasing the mounting sleeve towards a locked position (L), at least one latch arm connected to one of either the front-end device or the back-end device, wherein the latch arm is deflectable in a radial direction, wherein the mounting sleeve in the locked position (L) is arranged to prevent the radial deflection of the latch arm and wherein the mounting sleeve in the unlocked position allows for a radial deflection of the latch arm, so as to allow the latch arm to be deflected on assembly or disassembly of the front-end device to the back-end device and to latch to or unlatch from the other of the front-end device or the back-end device.
    • 本发明涉及一种用于自动注射器(A)的压缩连接装置,其中压缩连接装置适于将自动注射器(A)的前端装置附接到自动注射器的后端装置( A)包括环形安装套筒,所述环形安装套筒可平行于锁定位置(L)和解锁位置之间的纵向轴线(X)轴向移动,至少将安装套筒朝向锁定位置(L)偏置的安装套筒弹簧 一个闩锁臂连接到前端装置或后端装置中的一个,其中所述闩锁臂可沿径向方向偏转,其中所述锁定位置(L)中的所述安装套筒布置成防止所述锁定臂的径向偏转 所述锁定臂并且其中所述安装套筒处于所述解锁位置允许所述闩锁臂的径向偏转,以便允许所述闩锁臂在将所述前端装置组装或拆卸到所述后端装置时被偏转,并且 锁定或解锁 来自前端设备或后端设备中的另一个。

    • The invention refers to an auto-injector for administering a medicament (M), comprising of a chassis, a syringe with a hollow needle and a stopper; a drive spring capable of, upon activation: advancing the needle (3), injecting the medicament (M), and retracting the syringe with the needle after delivering the medicament (M); and; activating means arranged to lock and release the drive spring, wherein the drive spring is a compression spring arranged to be grounded at a distal end in the chassis for advancing the needle and for injecting the dose of medicament (M) via a plunger and wherein the drive spring is arranged to have its ground in the chassis switched to its proximal end for retracting the syringe. A refraction sleeve is axially movable arranged around the syringe, wherein the retraction sleeve is fixable in a maximum proximal position for providing ground at the distal end of the drive spring, wherein the retraction sleeve is arranged to take the syringe with it when released and translated in distal direction (D), wherein the compression spring is wrapped over the retraction sleeve with its distal end bearing against a thrust face on the retraction sleeve and with its proximal end bearing against a thrust collar arranged to be coupled to the plunger for joint axial translation for advancing the needle and for injecting the dose of medicament (M) and to decouple from the plunger for retraction.
    • 本发明涉及一种用于给药药物(M)的自动注射器,所述药物(M)包括底盘,具有中空针头的注射器和塞子; 驱动弹簧,其能够在激活后:递送所述针(3),注射所述药物(M),并且在递送所述药物(M)之后用所述针回缩所述注射器; 和; 激活装置,其布置成锁定和释放所述驱动弹簧,其中所述驱动弹簧是压缩弹簧,所述压缩弹簧布置成在所述底盘中的远端处接地,用于推进针头并且用于经由柱塞喷射剂量的药物(M),并且其中 驱动弹簧布置成使其底盘中的地面切换到其近端以缩回注射器。 折射套筒可围绕注射器轴向移动,其中缩回套筒可固定在最大近端位置,用于在驱动弹簧的远端处提供地面,其中缩回套筒布置成在释放和翻转时将注射器带入注射器 在远端方向(D)上,其中压缩弹簧被卷绕在缩回套筒上,其远端轴承抵靠在缩回套筒上的止推面上,并且其近端轴承抵靠布置成联接到柱塞的止推环,用于接合轴向 用于推进针头和用于注射剂量的药物(M)的平移并且与柱塞脱离以用于收缩。
