Abstract
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.
