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.

First claim

The invention claimed is:

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.
