Abstract

A delivery device for and method of delivering a metered amount of substance, the delivery device comprising: a mouthpiece through which a user in use exhales; an outlet through which substance is in use delivered; a housing fluidly connected to the mouthpiece and the outlet, such that exhalation by the user through the mouthpiece creates an air flow through the housing and from the outlet; and a substance-dispensing unit which is disposed within the housing and operative to dispense a metered amount of substance into an entraining air flow as created through the housing.

Claims

1. A delivery device for delivering a metered amount of a substance, the delivery device comprising:

a mouthpiece unit including a mouthpiece through which a user can in use exhale;

an outlet unit through which the substance is in use delivered;

a substance-supply unit which is actuatable to deliver the substance; and

a body unit in which the substance-supply unit is movably disposed between a storage configuration and an operative configuration;

wherein the mouthpiece unit is coupled to the substance-supply unit, the substance-supply unit being movable between the storage and operative configurations by movement of the mouthpiece unit;

wherein the substance-supply unit slides in a substantially linear direction, longitudinally within the body unit from the storage configuration to the operative configuration when the substance-supply unit is moved into the operative configuration; and

wherein the mouthpiece is articulated to the substance-supply unit and movable relative to the body unit when the substance-supply unit is in the operative configuration.

2. The delivery device of claim 1, wherein the outlet unit is integrally formed with the body unit.

3. The delivery device of claim 1, wherein the body unit comprises a housing which includes a cavity in which the substance-supply unit is slideably disposed.

4. The delivery device of claim 1, wherein:

the mouthpiece unit is fluidly connected to the substance-supply unit; and

the substance-supply unit is actuatable in response to exhalation by the user through the mouthpiece.

5. The delivery device of claim 1, wherein the substance-supply unit is actuatable in response to movement of the mouthpiece.

6. The delivery device of claim 1, wherein the outlet unit is a nosepiece and the delivery device is a nasal delivery device for delivering the substance to a nasal airway of the user.

7. The delivery device of claim 1, wherein the substance is a particulate substance.

8. The delivery device of claim 1, wherein the substance is a powdered substance.

9. The delivery device of claim 1, wherein the substance is a liquid substance.
