Abstract

A delivery device, e.g. an inhaler, comprises a rotatable metering member adapted to dispense a measured amount of material, a material delivery passage and a material delivery orifice and at least one actuator member adapted to move the metering member from a material retaining position to a material dispensing position. In a magazine comprising a plurality of metering members, the actuator and metering members may operate in a radial direction. A plurality of rotatable magazines may be utilized in the delivery device. The delivery device may be used to deliver a single or a combination therapy.

Claims

1. A delivery device comprising a rotatable first magazine, a rotatable second magazine, and a drive member interposed between the first and second magazines, the first and second magazines each being provided with a plurality of metering members, and the inhaler being arranged such that the drive member indexes the first magazine through a first series of dispensing configurations in each of which a metering member of the first magazine is actuatable so as to dispense a measured amount of material, and the drive member subsequently indexes the second magazine through a second series of dispensing configurations in each of which a metering member of the second magazine is actuatable so as to dispense a measured amount of material, wherein the inhaler is arranged so that the drive member is engaged with the first magazine and disengaged from the second magazine whilst the first magazine is being indexed through the first series of dispensing configurations, and the drive member is engaged with the second magazine and disengaged from the first magazine whilst the second magazine is being indexed through the second series of dispensing configurations.

2. A delivery device as claimed in claim 1, wherein each metering member contains a measured amount of material, and is openable by displacement relative to the first magazine and/or second magazine.

3. A delivery device as claimed in claim 1, wherein the first and second magazines are substantially circular.

4. A delivery device as claimed in claim 1, wherein the device comprises a material delivery passage, a material delivery orifice, and at least one push rod adapted to move a metering member from a material retaining position to a material dispensing position.

5. A delivery device as claimed in claim 4, wherein the device is provided with two push rods.

6. A delivery device as claimed in claim 1, wherein the material comprises a dry powder.

7. A delivery device as claimed in claim 1, wherein the material comprises a medicament.

8. A delivery device as claimed in claim 7, wherein the device is an inhaler.

9. A delivery device as claimed in claim 7, wherein the first and second magazines contain materials that comprise the same medicament.

10. A delivery device as claimed in claim 7, wherein the first and second magazines contain materials that comprise different medicaments.

11. A delivery device as claimed in claim 10, wherein the medicaments comprise fluticasone and salmeterol.

12. A delivery device as claimed in claim 7, wherein the first and second magazines each contain a material that comprises a combination therapy.

13. A delivery device as claimed in claim 12, wherein the combination therapy comprises fluticasone and salmeterol.
