Abstract

An inhaler, particularly for a horse, having a reservoir for dispensing a medicament preparation held under excess pressure, with a discharge nozzle for forming an aerosol of the medicament preparation and with a chamber for holding and temporarily storing the aerosol, which is located on the outlet side, a respiratory orifice adapter for a respiratory orifice, particularly a nostril, while according to a first aspect the reservoir is secured in position, at least in the axial direction, according to a second aspect the discharge nozzle has a direction of discharge which is inclined by more than 5° and less than 50° relative to a central axis of the reservoir or a direction of actuation for dispensing the aerosol, and according to a third aspect, the reservoir has a dispensing valve which is arranged at the top in the position of use of the inhaler.

First claim

What is claimed is:

1. An inhaler comprising: a reservoir with a liquid medicament preparation held under pressure, an inhaler housing in which the reservoir is located, a discharge nozzle for forming an aerosol of the medicament preparation that is connected to receive the medicament preparation from the reservoir, a chamber connected for receiving the aerosol from the discharge nozzle and for holding and temporarily storing the aerosol, the chamber comprising a respiratory adapter with a dispensing opening, said respiratory orifice adapter being at an outlet end of the chamber with the dispensing opening of the respiratory orifice adapter being laterally offset relative to the discharge nozzle and said chamber, and wherein the discharge nozzle has a direction of discharge which causes a central axis of the aerosol formed to be inclined by more than 5° and less than 50° relative to a central axis of the discharge nozzle.

2. Inhaler according to claim 1 , wherein the reservoir comprises an immersion tube which is fluidically connected to a valve of the reservoir.

3. Inhaler according to claim 1 , wherein the inhaler comprises a lever-like actuating element for triggering the aerosol formation, the activating element being mounted to the housing such that the activating element opens a valve of the reservoir for forming aerosol.

4. Inhaler according claim 1 , wherein the inhaler comprises an axially movable activating element, the medicament preparation being capable of being dispensed by the movement of the activating element.

5. Inhaler according to claim 1 , wherein the inhaler comprises a holder for an insert.

6. Inhaler according to claim 5 , wherein the insert comprises the reservoir.

7. Inhaler according to claim 5 , wherein the insert is axially insertable or inserted into the holder.

8. Inhaler according to claim 5 , wherein the holder comprises a retaining portion for at least axially retaining the reservoir.

9. Inhaler according to claims 5 , wherein the holder is formed by or in a handle or holding grip.

10. Inhaler according to claim 5 , wherein the holder comprises an orientation device for orienting insertion of the insert.

11. Inhaler according to claim 5 , wherein the holder comprises a release portion for releasing the dispensing of the medicament preparation by insertion of the insert.

12. Inhaler according to claim 11 , wherein the dispensing of the medicament preparation is releasable by total insertion of the insert in an intended orientation.

13. Inhaler according to claim 1 , wherein the inhaler comprises a replaceable counter.

14. Inhaler according to claim 13 , wherein the inhaler comprises a holder for an insert, and wherein the replaceable counter being adapted to be inserted in the holder.

15. Inhaler according to claim 1 , wherein the inhaler comprises a blocking device which is configured to at least one of: prevent accidental actuation, prevent actuation with the insert not fully inserted, and prevent any further dispensing of the medicament preparation or actuation after a predefined number of actuations has been reached or exceeded.

16. Inhaler according to claim 10 , wherein the direction of discharge of the discharge nozzle is fixed, predetermined or set by means of the orientation device.

17. Inhaler according to claim 1 , wherein the discharge nozzle comprises at least three discharge openings.

18. Inhaler according claim 17 , wherein the discharge openings have a cumulative outlet surface of more than 0.1 mm 2 .

19. Inhaler according claim 1 , wherein the reservoir is secured in position, at least in the axial direction.

20. Inhaler according claim 1 , wherein the reservoir comprises a valve which is arranged at the top in the position of use of the inhaler.
