Abstract

A delivery device, e.g. an inhaler, includes 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 including 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 first rotatable magazine and a second rotatable magazine, each magazine being provided with a plurality of metering members adapted to dispense a measured amount of material, the plurality of metering members being movably mounted within the respective magazines,

a first push rod adapted to move a metering member of the first rotatable magazine relative to the first rotatable magazine from a material retaining position to a material dispensing position,

a second push rod adapted to move a metering member of the second rotatable magazine relative to the second rotatable magazine from a material retaining position to a material dispensing position,

a material delivery passage, and

a material delivery orifice.

2. A delivery device as claimed in claim 1, wherein the first and second push rods are adapted to operate together.

3. A delivery device as claimed in claim 1, wherein the first and second push rods are adapted to operate independently.

4. A delivery device as claimed in claim 1, wherein the first and second push rods are adapted to operate sequentially.

5. A delivery device according to claim 1, wherein the material is a dry powder.

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

7. A delivery device according to claim 6, wherein the medicament delivery device is an inhaler.

8. A method of administering a medicament using an inhaler according to claim 7.

9. A method according to claim 8 characterised in that a combination of medicaments are administered.

10. A method of treatment of a patient suffering from a respiratory disorder comprising the administration of a therapeutically effective amount of a medicament using an inhaler according to claim 7.

11. A delivery device according to claim 6, wherein the first and second magazines contain the same medicament.

12. A delivery device according to claim 6, wherein the first and second magazines contain different medicaments.

13. A delivery device as claimed in claim 6, wherein the first and second magazines each contain a material that comprises a combination therapy.

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

15. A method of delivering a material which comprises using a delivery device according to claim 1.
