Abstract

A nebulizer and a housing part removably connected thereto, each having one or more coding elements. At least one of the coding elements is configured to be mounted in different defined positions on the nebulizer or the housing part and is removably connected thereto so that in each position a different coding is obtained in which the one or more coding elements match one another.

Claims

1. A nebuliser (1) for a fluid (2), into which a container (3) holding the fluid (2) is inserted, the nebulizer comprising:

a pressure generator (5) for conveying and/or nebulising the fluid (2);

a first housing part (16, 17);

a second housing part (18) which is removable from the first housing part (16) for the insertion of the container (3); and

coding means formed by two or more separate parts, which are mountable on the nebulizer in different defined positions such that;

(i) in each position a different coding is obtained as between the two or more separate parts;

(ii) in only one of the different defined positions a match between the two or more separate parts is obtained in which the container (3) is configured to be inserted into the nebuliser (1) or used therewith; and

(iii) the only one of the different defined positions to achieve the match is adjustable, through relative movement of, and without replacement of, the two or more separate parts.

2. The nebuliser according to claim 1, wherein at least one of the two or more separate parts of the coding means is located on the first housing part (16, 17) and at least one other of the two or more separate parts of the coding means is located on the removable second housing part (18).

3. The nebuliser according to claim 2, wherein the at least one other of the two or more separate parts of the coding means associated with the removable second housing part (18) is configured in the manner of part of the wall of an imaginary hollow cylinder (H), the wall having at least one freely passable groove (260) extending in a direction of an axis of symmetry (S) of the imaginary hollow cylinder (H).

4. The nebuliser according to claim 3, wherein the at least one other of the two or more separate parts of the coding means associated with the removable second housing part (18) comprises a plurality of grooves (260,261), of which one groove (260) is freely passable and the other grooves (261) are rendered non-passable by transverse walls (262).

5. The nebuliser according to claim 2, wherein the container (3) is inseparable from the second housing part (18).

6. The nebuliser according to claim 1, wherein at least one of the two or more separate parts of the coding means is freely rotatable about an axis of the nebuliser (1), at least over a limited angular range, and by being pushed longitudinally along the axis of the nebuliser (1) is movable into a position in which the at least one of the two or more separate parts of the coding means is no longer rotatable.

7. The nebuliser according to claim 6, wherein the at least one of the two or more separate parts of the coding means associated with the nebuliser (1) is annular, or comprises a connecting or ring portion (302).

8. The nebuliser according to claim 7, wherein the at least one of the two or more separate parts of the coding means associated with the nebuliser (1) comprises at least one projection (301) projecting radially and/or outwardly.

9. The nebuliser according to claim 8, wherein the at least one projection (301) protrudes axially over the connecting or ring portion.

10. The nebuliser according to claim 7, wherein the connecting or ring portion (302) comprises engagement means, including inner teeth (303), for mounting or securing the at least one of the two or more separate parts of the coding means on the nebuliser (1).

11. The nebuliser according to claim 7, wherein the at least one of the two or more separate parts of the coding means associated with the nebuliser (1) is mounted or secured on the nebuliser (1) by snap-fit and/or form-fit, in particular engages with at least one tooth (303) into an engagement recess (304) or vice versa.

12. The nebuliser according to claim 7, wherein the at least one of the two or more separate parts of the coding means associated with the nebuliser (1) is mountable in different rotational positions on the nebuliser (1).

13. The nebuliser according to claim 7, wherein the nebuliser (1) comprises markings (33) indicating different rotational positions for facilitating setting the coding when mounting the at least one of the two or more separate parts of the coding means on the nebuliser (1).

14. The nebuliser according to claim 13, wherein a projection (301) or an indicator (304) of the at least one of the two or more separate parts of the coding means points to one of the markings (33) depending on the selected rotational position of the at least one of the two or more separate parts of the coding means.

15. The nebuliser according to claim 1, wherein the second housing part (18) comprises a non-circular and/or receiving portion (35) for a retaining element (19) of the nebuliser (1) and/or an engagement portion (36) so that the second housing part (18) is connectable to the nebuliser (1) only in a defined rotational position.

16. The nebuliser according to claim 15, wherein at least one other of the two or more separate parts of the coding means of the second housing part (18) is provided with at least one freely passable groove (270) located in different rotational positions depending on the coding of the nebuliser (1).

17. A nebuliser (1) for a fluid (2), into which a container (3) holding the fluid (2) is inserted, the nebulizer comprising:

a pressure generator (5) for conveying and/or nebulising the fluid (2);

a first housing part (16, 17);

a second housing part (18) which is removable from the first housing part (16) for the insertion of the container (3); and

coding means formed by two or more separate parts, which are mountable on the nebulizer in different defined positions such that;

(i) in each position a different coding is obtained as between the two or more separate parts;

(ii) in only one of the different defined positions a match between the two or more separate parts is obtained in which the container (3) is configured to be inserted into the nebuliser (1) or used therewith; and

(iii) the only one of the different defined positions to achieve the match is adjustable among the different defined positions in which the coding of the nebulizer (1) is set, wherein;

at least one of the two or more separate parts of the coding means is located on the first housing part (16, 17) and at least one other of the two or more separate parts of the coding means is located on the removable second housing part (18),

the at least one other of the two or more separate parts of the coding means associated with the removable second housing part (18) is configured in the manner of part of the wall of an imaginary hollow cylinder (H), the wall having at least one freely passable groove (260) extending in a direction of an axis of symmetry (S) of the imaginary hollow cylinder (H), and

the at least one other of the two or more separate parts of the coding means associated with the removable second housing part (18) comprises a plurality of grooves (260,261), of which one groove (260) is freely passable and the other grooves (261) are rendered non-passable by transverse walls (262).
