    • A dispensing device for dispensing metered dosages of a medicament from a container includes an indicator housing having an interior and an opening communicating with the interior. A first actuator is disposed within the interior and includes a resilient arm member defining a pawl portion. The first actuator is reciprocally moveable between an actuated position and an at-rest position. A spring is disposed in the indicator housing and biases the first actuator towards the at-rest position. A ratchet gear is rotatably disposed in the indicator housing, and is rotatable in response to the movement of the first actuator between the actuated and at-rest positions. An indicator is rotatably disposed in the indicator housing and is rotatable in response to the rotation of the ratchet gear. A second actuator is shaped to be received through the opening in the indicator housing. The second actuator and indicator housing are moveable relative to each other between first and second positions. The second actuator is inserted through the opening, contacts the first actuator and moves the first actuator to the actuated position when the second actuator and indicator housing are moved to the second position. The first actuator is biased to the at-rest position by the spring when the second actuator and the indicator housing are moved to the first position. A method of dispensing metered dosages of medicament is also provided.
    • 用于从容器分配药物的计量剂量的分配装置包括具有内部和与内部连通的开口的指示器壳体。 第一致动器设置在内部内并且包括限定棘爪部分的弹性臂构件。 第一致动器在致动位置和静止位置之间往复运动。 弹簧设置在指示器壳体中,并将​​第一致动器朝向静止位置偏压。 棘轮被可旋转地设置在指示器壳体中,并且可响应于第一致动器在致动位置和静止位置之间的运动而旋转。 指示器可旋转地设置在指示器壳体中并且可响应于棘轮的旋转而旋转。 第二致动器成形为通过指示器壳体中的开口被容纳。 第二致动器和指示器壳体可在第一和第二位置之间相对于彼此移动。 当第二致动器和指示器壳体移动到第二位置时,第二致动器穿过开口插入,接触第一致动器并将第一致动器移动到致动位置。 当第二致动器和指示器壳体移动到第一位置时,第一致动器被弹簧偏压到静止位置。 还提供了分配计量剂量的药物的方法。
