Abstract
A device for use with metered dose inhalers includes a housing configured with a void to receive a metered dose inhaler, an actuator assembly which is configured to selectively apply force to the metered dose inhaler to cause the metered dose inhaler to release medicament, and a cocking mechanism for placing the actuator assembly in an armed configuration. The device is configured to actuate the metered dose inhaler as the user inhales, thereby ensuring improved medicament delivery. Additionally, the device is configured to prevent the metered dose inhaler from remaining in a vented position.
Claims8
A method for automatically actuating a metered dose inhaler comprising:
- a) selecting a housing having:
- a cover having a closed position and an open position
- an actuator having a first, resting orientation, a second, armed orientation and a third, actuating orientation, and
- a void configured for receiving a metered dose inhaler, and
- a metered dose inhaler having:
- an actuator body, and
- a medicament canister disposed in the actuator body,
- the metered dose inhaler being disposed in the void of the housing;
- and
- b) inhaling through the housing to cause the actuator to forcefully engage the medicament canister of the metered dose inhaler to dispense medicament from the medicament canister;
- and
- wherein the method further comprises moving the cover from the closed position to the open position to move the actuator from the first, resting orientation to the second, armed orientation.
A method for automatically actuating a metered dose inhaler having a medicament canister containing medicament and an actuator body designed for use with the medicament canister, the method comprising:
- a) selecting a housing having a void configured for receiving the metered dose inhaler, an actuator for actuating the metered dose inhaler responsive to inhalation by the user, an opening through which a user inhales and a cover for covering the opening;
- b) disposing the metered dose inhaler in the housing;
- c) opening the cover of the housing to arm the actuator in the housing;
- and
- d) inhaling to cause the actuator to forcefully engage the medicament canister of the metered dose inhaler to dispense medicament from the medicament canister.
