    • An injection device (110) is provided which includes a syringe (122) having a discharge nozzle (118). The syringe is movable between a retracted position in which the discharge nozzle is contained within the housing and an extended position in which the discharge nozzle extends from the housing. A trigger (114) is activatable to allow the contents of the syringe to be discharged through the discharge nozzle. There is also a releasable locking mechanism (116) which, when engaged, prevents the trigger from moving into an active position. The trigger includes a first portion (150) having a cut-out (152) which extends from a first end of the trigger in a direction substantially parallel to the first axis (101). The releasable locking mechanism includes a protrusion (154) along a second axis (181) for communicating with the first portion of the trigger when the releasable locking mechanism is engaged and for communicating with the cut-out when the releasable locking mechanism is disengaged. Such an injection device provides improved protection against accidental activation of the trigger.
    • 提供了一种注射装置(110),其包括具有排出喷嘴(118)的注射器(122)。 注射器可以在其中排出喷嘴容纳在壳体中的缩回位置和排出喷嘴从壳体延伸的延伸位置之间移动。 触发器(114)可激活以允许注射器的内容物通过排出喷嘴排出。 还有一个可释放的锁定机构(116),其在接合时防止触发器进入活动位置。 触发器包括具有从基本上平行于第一轴线(101)的方向从触发器的第一端延伸的切口(152)的第一部分(150)。 可释放的锁定机构包括沿着第二轴线(181)的突出部(154),用于当可释放的锁定机构接合时与触发器的第一部分相通,并且当可释放的锁定机构脱离时用于与切口连通。 这种注射装置提供改进的防止触发器的意外激活的保护。

    • An injection device comprises a housing adapted to receive a syringe having a discharge nozzle, the syringe being moveable in the housing on actuation of the injection device along a longitudinal axis from a retracted position in which the discharge nozzle is contained within the housing and an extended position in which the discharge nozzle of the syringe extends from the housing through an exit aperture. There is an actuator and a drive adapted to be acted upon by the actuator and in turn act upon the syringe to advance it from its retracted position to its extended position and discharge its contents through the discharge nozzle. A locking mechanism is moveable from an engaged position in a direction into the housing at the exit aperture into a disengaged position. The locking mechanism is adapted to prevent actuation of the device when it is in its engaged position and permit actuation of the device when it is in its disengaged position. The exit aperture is defined by a rim located on an edge of the housing and the locking mechanism comprises a contact surface which is adapted to extend over or around at least a part of the rim.
    • 注射装置包括适于接纳具有排出喷嘴的注射器的壳体,所述注射器可以沿着纵向轴线从所述排出喷嘴容纳在所述壳体内的缩回位置致动所述注射装置在所述壳体中移动,并且延伸 注射器的排出喷嘴从壳体通过出口孔延伸的位置。 存在致动器和驱动器,其适于由致动器作用并且继而作用在注射器上以将其从其缩回位置推进到其延伸位置,并且通过排出喷嘴排出其内容物。 锁定机构可以从接合位置沿一个方向移动到出口孔处的壳体中到脱离位置。 锁定机构适于在装置处于其接合位置时防止装置的致动,并允许装置处于其脱离位置时致动。 出口孔由位于壳体的边缘上的边缘限定,并且锁定机构包括接触表面,该接触表面适于在轮辋的至少一部分上方或周围延伸。
