The delivery device can include an interface unit, as a replaceable unit, having at least one nosepiece unit for fitting to a respective nostril of a subject, a nozzle from which substance is in use delivered, and at least one delivery unit having a substance supply unit for delivering substance to the nozzle of the at least one nosepiece unit. The delivery device can also include an actuation unit for actuating the at least one delivery unit of the interface unit.

First claim

I claim:

1. A nasal delivery device for delivering a substance to a nasal airway of a subject, comprising:
an interface unit configured to be attachable to an actuation unit, wherein the interface unit is attachable to the actuation unit in a first unaligned position and is movable to a second aligned position, wherein the interface unit is actuatable only in the aligned position;
the interface unit including a nosepiece unit, a mouthpiece and a delivery unit, the nosepiece unit configured for fitting to a respective nostril of the subject and the delivery unit including a substance supply unit actuatable to deliver the substance to the nosepiece unit.

2. The delivery device of claim 1 , wherein the substance is a powder.

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

4. The delivery device of claim 1 , wherein the interface unit is a single integral unit.

5. The delivery device of claim 1 , wherein the delivery unit is actuated in response to exhalation by the subject.

6. The delivery device of claim 5 , wherein the mouthpiece and the nosepiece unit of the interface unit are fluidly connected.

7. The delivery device of claim 1 , wherein the interface unit is one of a plurality of interface units each attached to a common support.

8. The delivery device of claim 7 , wherein the common support is a belt.

9. A nasal delivery device for delivering a substance to a nasal airway of a subject, comprising:
an interface unit configured to be attachable to an actuation unit, wherein the interface unit is attachable to the actuation unit in a first unaligned position and is slidably movable through the unaligned position to a second aligned position, wherein the interface unit is actuatable only in the aligned position;
the interface unit including a nosepiece unit and a delivery unit, the nosepiece unit configured for fitting to a respective nostril of the subject and the delivery unit including a substance supply unit actuatable to deliver the substance to the nosepiece unit.

10. The delivery device of claim 9 , wherein the substance is a powder.

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

12. The delivery device of claim 9 , wherein the interface unit is a single integral unit.

13. The delivery device of claim 9 , wherein the delivery unit is actuated in response to exhalation by the subject.

14. The delivery device of claim 9 , wherein the interface unit further comprises a mouthpiece.

15. The delivery device of claim 14 , wherein the mouthpiece and the nosepiece unit of the interface unit are fluidly connected.

16. The delivery device of claim 9 , wherein the interface unit is one of a plurality of interface units each attached to a common support.
