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.

Claims

1. Inhaler for insertion into a nostril, comprising:

an inhalation valve which has a movable valve element and a valve body seat for the valve element, and

a discharge nozzle for producing an aerosol,

wherein the valve body seat has a sealing edge which forms an opening accommodating the discharge nozzle, and

wherein an opening of the discharge nozzle is arranged downstream from the valve body seat.

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

3. Inhaler according to claim 1, wherein the inhalation valve is configured as one-way or non-return valve.

4. Inhaler according to claim 3, 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.

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

6. Inhaler according to claim 1, wherein the inhalation valve opens only on an inner edge of the valve element.

7. Inhaler according to claim 6, wherein the inhalation valve is configured to created to produce an air stream that forms a jacket around the aerosol.

8. Inhaler for insertion into a nostril, comprising:

an inhalation valve which has a movable annular valve element and a stop for the valve element,

a discharge nozzle for producing an aerosol, and

a chamber which is designed for uptake of the aerosol,

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, and

wherein the valve element rests snugly on the stop in an open position of the valve.

9. Inhaler according to claim 8, wherein the stop is located on a side of the valve element that faces away from the valve body seat.

10. Inhaler according to claim 8, wherein the stop prevents overexpansion and damage of the valve element.

11. Inhaler according to claim 8, wherein the valve element with the chamber forms a nozzle.

12. Inhaler according to claim 11, wherein a flow cross-section decreases by means of the valve element in the direction of flow and then increases by the chamber in the direction of flow.

13. Inhaler according to claim 8, wherein the intake opening of the chamber 6 has a conically-narrowing section

14. Inhaler according to claim 13, wherein the conically-narrowing section is free-standing.

16. Inhalation valve according to claim 14, wherein the valve body seat is connected via at least one arm to the fastening element.

17. Inhalation valve according to claim 14, further comprising a clamping ring for clamping the valve element to the fastening element.

18. Inhalation valve according to claim 14, wherein the valve element is pre-tensioned against the valve body seat.

19. Inhalation valve according to claim 14, 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.

15. 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, and

a fastening element for circumferential fastening of the valve element,

wherein the outer edge of the valve element is snugly fastened all the way around, the inhalation valve opens only on the inner edge of the valve element, the valve body seat has a sealing edge forming a through passage for guiding-through of a discharge nozzle, and the fastening element and the valve body seat are formed in one piece.
