Abstract An injection device is presented that incorporates a dose setting mechanism, wherein the dose setting mechanism includes a fail-safe feature that activates during an interrupted dose delivery event. A dose selector having a protruding rib engages a protrusion on the snap element to prevent distal movement of the dose knob with removal of axial force in a proximal direction during dose delivery by a user. The dose setting mechanism may further include features to prevent reuse. 提出了一种结合剂量设置机构的注射装置，其中剂量设置机构包含在中断的剂量输送事件期间激活的失效保护特征。具有突出肋的剂量选择器接合卡扣元件上的突起，以防止剂量旋钮在用户在剂量输送期间在近侧方向上移除轴向力的情况下向远侧移动。该剂量设置机构可以进一步包括防止重复使用的特征。
