Metered dose inhaler applicator
A metered dose inhaler (“MDI”) applicator is disclosed that includes a carrier, a housing, an adjuster and a lever. The carrier defines an aperture configured to receive a boot of a MDI. The housing is configured to be assembled with the carrier and to move in a vertical direction within the MID applicator relative to the carrier. The adjuster is configured to move between a locked position and an unlocked position, wherein when the adjuster is in the locked position, the adjuster is configured to prevent the carrier and the housing from moving in one or more directions relative to one another. The lever is pivotally connected to the housing and is configured to transfer a force applied to the lever to a canister of the MDI and to actuate the MDI to dispense an aerosolized medicine.
1. A metered dose inhaler (“MDI”) applicator comprising:
a carrier defining an aperture opening in a first direction and configured to receive a boot of a MDI;
a housing moveably coupled to the carrier, wherein the housing and the carrier are moveable relative to one another in a second direction transverse to the first direction;
a lever pivotally connected to the housing; and
an adjuster moveably coupled to the housing, wherein the adjuster is moveable relative to the housing between a locked position and an unlocked position, wherein when the adjuster is in the locked position the adjuster is engaged with the carrier and restricts movement in at least one direction between the carrier and the housing.
2. The MDI applicator of claim 1 , wherein the adjuster defines at least one tooth and the carrier defines a complementary set of teeth, and wherein the at least one tooth engages at least a portion of the set of teeth of the carrier when the adjuster is in the locked position.
3. The MDI applicator of claim 1 wherein the housing and carrier are moveable relative to each other in a first direction, and wherein the adjuster is moveable relative to the housing in a second direction perpendicular to the first direction.
4. The MDI applicator of claim 1 wherein the adjuster is pivotally connected to the housing.
5. The MDI applicator of claim 1 wherein the adjuster is translatably connected to the housing.
6. The MDI applicator of claim 5 wherein the housing comprises a track and the adjuster comprises a guide member moveable within the track.
7. The MDI applicator of claim 1 wherein the carrier is translatably connected to the housing.
8. The MDI applicator of claim 1 wherein the lever comprises a downwardly extending protrusion.
9. The MDI applicator of claim 1 further comprising a canister disposed in the housing.
10. The MDI applicator of claim 9 wherein the canister contains a medicine.
11. The MDI applicator of claim 1 wherein the carrier and housing are telescopically connected.
12. The MDI applicator of claim 1 wherein the first and second directions are substantially orthogonal.
13. A metered dose inhaler (“MDI”) applicator comprising:
a carrier defining an aperture configured to receive a boot of a MDI;
a housing moveably coupled to the carrier, wherein the housing and the carrier are moveable in a vertical direction relative to one another;
a lever pivotally connected to the housing; and
an adjuster moveably coupled to the housing, wherein the adjuster is moveable relative to the housing between a locked position and an unlocked position, wherein when the adjuster is in the locked position, the carrier is moveable in one direction relative to the housing thereby allowing a height of the MDI applicator to decrease.
14. A metered dose inhaler (“MDI”) applicator comprising:
a carrier defining an aperture configured to receive a boot of a MDI;
a housing moveably coupled to the carrier, wherein the housing and the carrier are moveable in a vertical direction relative to one another;
an adjuster moveably coupled to the housing, wherein the adjuster is moveable relative to the housing between a locked position and an unlocked position, wherein when the adjuster is in the locked position the adjuster is engaged with the carrier and restricts movement in at least one direction between the carrier and the housing;
a lever pivotally connected to the housing; and
a canister holding a medicine disposed in the housing, wherein the lever is positionable against an end of the canister.
15. A metered dose inhaler (“MDI”) applicator comprising:
a carrier defining an aperture configured to receive a boot of a MDI;
a housing moveably coupled to the carrier, wherein the housing and the carrier are moveable in a vertical direction relative to one another, wherein the carrier is translatably connected to the housing, and wherein the housing comprises a track and the carrier comprises a guide member moveable within the track; and
a lever pivotally connected to the housing.
16. A metered dose inhaler (“MDI”) applicator comprising:
a carrier defining an aperture opening in a first direction and configured to receive a boot of a MDI;
a housing moveably coupled to the carrier, wherein the housing and the carrier are moveable relative to one another in a second direction transverse to the first direction; and
a lever pivotally connected to the housing, wherein the pivotal connection between the lever and the housing is slideable between spaced apart first and second positions.
17. A method of using a metered dose inhaler (“MDI”) applicator comprising:
inserting a portion of a MDI in a first direction through an aperture of a carrier and engaging the MDI with the carrier;
moving the carrier and MDI in a second direction relative to a housing to a desired position, wherein the second direction is transverse to the first direction;
locking the carrier to the housing such that the carrier and MDI may not be moved relative to the housing in a direction opposite the second direction; and
engaging an end of the MDI with a lever pivotally connected to the housing.
18. The method of claim 17 wherein the locking the carrier to the housing comprises moving an adjuster relative to the housing from a first position wherein the adjuster is not engaged with the carrier to a second position wherein the adjuster is engaged with the carrier.
19. The method of claim 18 wherein the adjuster defines at least one tooth and the carrier defines a complementary set of teeth, and wherein moving the adjuster relative to the housing to the second position comprises engaging at least a portion of the set of teeth of the carrier with at least one tooth of the adjuster.
20. The method of claim 18 wherein moving the adjuster relative to the housing comprises moving the adjuster relative to the housing in a third direction perpendicular to the second direction.
21. The method of claim 18 wherein the housing comprises a track and the adjuster comprises a guide member, and wherein moving the adjuster relative to the housing comprises translating the adjuster relative to the housing by moving the guide member within the track.
22. The method of claim 17 wherein the MDI comprises an actuator boot having a housing portion defining a cavity extending in the second direction and a mouthpiece portion extending in the first direction from the housing portion, and a container disposed in the cavity of the housing portion of the actuator boot, wherein the mouthpiece portion is inserted in the first direction through the aperture of the carrier, and wherein the container defines the end of the MDI.
23. The method of claim 22 further comprising pivoting the lever relative to the housing, and thereby moving the container relative to the boot in the second direction and dispensing a dose of medicament from the container.
24. The method of claim 17 further comprising moving the carrier and MDI in the second direction relative to the housing after locking the carrier to the housing and thereby decreasing a height of the MDI applicator.
