Abstract

The inhalation therapy device according to the invention comprises a nebulizer chamber which accommodates an aerosol generator that emits aerosol into the nebulizer chamber. A valve that has a valve seat, a resilient valve member and a valve member positioning means is arranged at an opening of the nebulizer chamber. The valve member positioning means can be moved out of a first position and into a second position so as to position the valve member on the valve seat in such a manner that in the first position, the valve member, in a flow-free state, is positioned on the valve seat in a pre-tensioned manner and in a second position, is spaced apart from the valve seat.

Claims

1. An inhalation therapy device comprising:

a nebulizer chamber,

an aerosol generator arranged such as to emit a generated aerosol into said nebulizer chamber,

at least one opening in a wall of said nebulizer chamber, and

at least one valve arranged on said at least one opening in said wall of said nebulizer chamber,

wherein said valve comprises;

a valve seat,

a resilient valve member and

a valve member positioning means,

said valve member positioning means being movable, relative to said valve seat, out of a first position and into a second position

such that in the first position, said resilient valve member, in a flow-free state, is positioned on said valve seat by said valve member positioning means, so that said valve seat is provided on one side of said resilient valve member and said valve member positioning means is provided on an opposite side of said resilient valve member, and

so that, in the second position which is different from said first position and in which said valve is in an opened state for cleaning said valve and in which said resilient valve member remains securely fixed on said valve, said resilient valve member is spaced apart from said valve seat, wherein in said second position said resilient valve member remains securely connected at a fixing point while the valve seat, the resilient valve member, and the valve member positioning means are accessible for cleaning without concealed areas, and

wherein the valve member positioning means and the valve seat are attached to each other by a hinge and are configured to be moved apart relative to each other from said first position to said second position.

2. The inhalation therapy device according to claim 1, wherein the spacing apart is achieved by a fixing of the valve member.

3. The inhalation therapy device according to claim 1, wherein said valve member is attached in the vicinity of or to said valve member positioning means.

4. The inhalation therapy device according to claim 1, wherein said valve member is attached in the vicinity of or to said valve seat.

5. The inhalation therapy device according to claim 1, wherein said valve member is positioned with pre-tension on said valve seat.

6. The inhalation therapy device according to claim 5, wherein the pre-tension is produced by bending said valve member.

7. The inhalation therapy device according to claim 6, wherein said valve seat has a curved, rounded or sloping design so as to bend said valve member positioned on said valve seat to produce the pre-tension.

8. The inhalation therapy device according to claim 1, wherein a portion of said wall, in which said opening is disposed, is movable relative to said nebulizer chamber.

9. The inhalation therapy device according to claim 8, wherein the movable portion of said wall is designed as a lid of said nebulizer chamber.

10. The inhalation therapy device according to claim 9, wherein said lid is attached in a fold-down manner to a stationary part of said nebulizer chamber.

11. The inhalation therapy device according to claim 8, wherein said movable portion, in particular said lid, is attached in a fold-down manner by said hinge.

12. The inhalation therapy device according to claim 11, wherein said hinge is bi-stable.

13. The inhalation therapy device according to claim 8, wherein said valve seat is provided on said movable portion, in particular a lid, and said valve member positioning means is provided on a stationary part of said nebulizer chamber.

14. The inhalation therapy device according to claim 8, wherein said valve member positioning means is provided on said movable portion, in particular said lid, and said valve seat is provided on said stationary part of said nebulizer chamber.

15. The inhalation therapy device according to claim 1, wherein said movable portion, in particular on said lid, can be locked in a closed state by means of at least one snap connection.

16. The inhalation therapy device according to claim 1, wherein at least two of the valve seat, the valve member and the valve member positioning means are injection-moulded as a single part from different materials.

17. The inhalation therapy device according to claim 1, wherein the valve seat, the valve member and/or the valve member positioning means are produced in a two-component injection-moulding process.

18. The inhalation therapy device according to claim 1, wherein said valve member is essentially made of a softer material than said valve seat and/or said valve member positioning means.

19. The inhalation therapy device according to claim 1, wherein said valve member is essentially made of silicone rubber or thermoplastic elastomer.

20. The inhalation therapy device according to claim 1, wherein said valve seat comprises a circumferential sealing lip.

21. The inhalation therapy device according to claim 1, wherein said valve is an inhalation valve or an exhalation valve.

22. An inhalation therapy device comprising:

a nebulizer chamber,

an aerosol generator arranged such as to emit a generated aerosol into said nebulizer chamber,

at least one opening in a wall of said nebulizer chamber, and

at least one valve arranged on said at least one opening in said wall of said nebulizer chamber,

wherein said valve comprises;

a valve seat and

a resilient valve member,
