Abstract

An inhaler, preferably for insertion into a nostril, in particular a horse's nostril, with an inhalation valve, which has a movable valve element, whereby the valve element is designed in an annular manner and has an outer edge and an inner edge, whereby the valve element is fastened at the outer edge, the inner edge forms the boundary of an indentation of the valve element, and the inhalation valve has a valve body seat that corresponds to the inner edge.

First claim

What is claimed is:

1. An inhaler for insertion into a nostril, comprising:
an inhalation valve which has a valve body seat, and an annular valve element which is deflectable off of the valve body seat only at an inner edge, and a stop for limiting maximum deflection of the inner edge of the valve element,
a discharge nozzle for producing an aerosol, and
a chamber configured for taking in of the aerosol from the nozzle,
wherein the chamber is arranged downstream from the discharge nozzle,
wherein the stop is formed by an edge of an intake opening of the chamber,
wherein the stop corresponds in shape and diameter to the inner edge of the valve element,
wherein the valve element rests snugly on the stop in an open position of the valve, and
wherein the valve element is secured on an outer edge remote from the discharge nozzle so that the outer edge remains fixed when the inner edge is deflected off of the valve body seat.

2. The inhaler according to claim 1 , wherein the stop is located on a side of the valve element that faces away from the valve body seat.

3. The inhaler according to claim 1 , wherein the stop is positioned to prevent overexpansion and damage of the valve element.

4. The inhaler according to claim 1 , wherein the valve element with the chamber forms a nozzle.

5. The inhaler according to claim 4 , wherein a flow cross-section decreases by means of the valve element in a direction of flow and then increases by the chamber in the direction of flow.

6. The inhaler according to claim 1 , wherein the intake opening of the chamber has a conically-narrowing section.

7. The inhaler according to claim 6 , wherein the conically-narrowing section is free-standing.

8. The inhaler according to claim 1 , wherein a dispensing direction of the discharge nozzle corresponds to a direction of air flow through the inhalation valve.

9. The inhaler according to claim 1 , wherein the inhalation valve is configured as a one-way or non-return valve.

10. The inhaler according to claim 9 , wherein the inhalation valve enables inflowing of ambient air from outside the inhaler through the inhalation valve and prevents exiting of air from the inhaler through the inhalation valve.

11. The inhaler according to claim 1 , wherein the valve element is at least one of prestressed against the valve body seat in a sealing manner, flexible, bendable, flat, thin, annular, disk-shaped conical at least in sections, and membrane-shaped.

12. The inhaler according to claim 1 , wherein the inhalation valve is configured to produce an air stream that forms a jacket around the aerosol.

13. An inhalation valve for an inhaler, comprising:
a movable annular valve element with an outer edge and an inner edge,
a valve body seat for the valve element,
a fastening means circumferentially fastening the valve element for securing an outer edge of the valve element in position on the valve body seat, and
a stop for limiting maximum deflection of the inner edge of the valve element, wherein the stop is formed by an edge of an intake opening of a chamber configured for taking in of an aerosol,
wherein the outer edge of the valve element is snugly fastened all the way around by the fastening means and the inner edge is unsecured so that the inhalation valve opens only on the inner edge of the valve element by being deformed away from the valve body seat, and
wherein the valve body seat has a sealing edge forming a through passage for guiding-through of a discharge nozzle.

14. The inhalation valve according to claim 13 , wherein the fastening means comprises a clamping ring for clamping the valve element to the fastening element.

15. The inhalation valve according to claim 13 , wherein the valve element is pretensioned against the valve body seat.

16. The inhalation valve according to claim 13 , wherein at least one of the valve element, the inner edge of the valve element, and the valve body seat are arranged with one another in such a way that focal points or geometric foci lie on a common axis.

17. The inhalation valve according to claim 13 , wherein a dispensing direction of the discharge nozzle corresponds to a direction of air flow through the inhalation valve.

18. The inhalation valve according to claim 13 , wherein the inhalation valve is configured as a one-way or non-return valve.

19. The inhalation valve according to claim 13 , wherein the valve element is at least one of prestressed against the valve body seat in a sealing manner, flexible, bendable, flat, thin, annular, disk-shaped conical at least in sections, and membrane-shaped.

20. The inhalation valve according to claim 13 , wherein the inhalation valve is configured to produce an air stream that forms a jacket around the aerosol.
