Abstract

The present invention relates to an inhalation device used for inhalation of the medicament in dry powder form from capsules.

Claims

1. An inhalation device for inhalation of a medicament in dry powder form from capsules, the device comprising:

a bottom-casing (4),

a mid-plate (3) covering the bottom-casing (4),

a capsule chamber (11) integrated with the mid-plate to place the capsule,

a filter (7) to filter the medicament in dry powder form,

a filter connector (6) to hold the filter (7),

a mouthpiece (2) that closes over the mid-plate (3)and into which the filter connector (6) is inserted,

a mouthpiece cover (1) to cover the mouthpiece (2),

a hinge (10) providing a connection between the mouthpiece cover (1), the mouthpiece (2), the mid-plate (3) and the bottom-casing (4),

at least one needle (12b, 12c) to pierce the capsule in the capsule chamber (11),

a movable press button (9) to push the at least one needle (12b, 12c) into the capsule chamber (11),

a safety lock button (8) to prevent movement of the mouthpiece (2) and the mouthpiece cover (1) when the inhalation device is in sleep mode, and

locking latches (8a, 8b) situated on an upper side of the safety lock button (8) that interlock with holes of extensions (6c, 6d, 1b, 1c) belonging to the filter connector (6) and mouthpiece cover (1), wherein;

the safety lock button (8) is connected with both the filter connector (6) inserted into the mouthpiece (2) and the mouthpiece cover (1) and wherein

when the safety lock button (8) is in actuation position, the locking latches (8a, 8b) detach from the extensions (6c, 6d, 1b, 1c) and both the mouthpiece cover (1) and the mouthpiece (2) are released simultaneously.

2. The inhalation device according to the claim 1, wherein the connection among the safety lock button (8), the filter connector (6), and the mouthpiece cover (1) is enabled by interlocking of the extensions (6c, 6d, 1b, 16c) situated on the filter connector and the mouthpiece cover to the locking latches (8a, 8b) situated on the upper side of the safety lock button.

3. The inhalation device according to the claim 2, wherein the extensions (6c, 6d, 1b, 1c) of the filter connector (6) and the mouthpiece cover (1) are respectively situated under the mouthpiece (2) and the mouthpiece cover (1), wherein when the mouthpiece and the mouthpiece cover are closed, the extensions are inserted into the bottom-casing (4).

4. The inhalation device according to claim 1, wherein the locking latch (8a) is interlocked to the extension (1b) under the mouthpiece cover (1) while the locking latch (8b) is interlocked to the extension (6c) belonging to the filter connector when the safety lock button (8) is in sleep mode.

5. The inhalation device according to claim 1, wherein the device has nails (2d) that form on the exterior surface of the mouthpiece (2) as the filter connector (6) interlocks with the mouthpiece (2), and wherein the device comprises holes (1d, 1e) situated on the inner surface of the mouthpiece cover (2) into which the nails can insert.

6. The inhalation device according to claim 1, wherein the mouthpiece (2) comprises a hinge element (2a) situated on the side of the mouthpiece with a protruding structure that prevents the movement of the mouthpiece (2) more than 90°

.

7. The inhalation device according to claim 1, wherein the mouthpiece cover (1) and the mouthpiece (2) can be rotated together by 90°

.

8. The inhalation device according to claim 1, wherein the mouthpiece (2) can be rotated only by 90°

and the mouthpiece cover (1) can be rotated by 180°

.

9. The inhalation device according to claim 1, wherein the safety lock button (8) comprises a flexible part (8c) to move the safety lock button into the bottom-casing (4) when actuated and to revert back to its first position when released.

10. The inhalation device according to claim 1, wherein the press button (9) is configured to be actuated independently from the safety lock button (8).

11. The inhalation device according to claim 1, wherein the mouthpiece (2) comprises an air intake duct (5), one end of which reaches to an inlet of the mouthpiece (2) and the other end of which passes through the filter connector (6).

12. The inhalation device according to claim 1, wherein the medicament in dry powder form can be sieved through the filter (7) to enter into an air intake duct (5) without dispersing.

13. The inhalation device according to claim 1, wherein the capsule chamber (11) and the mid-plate (3) are adjacent to each other and the capsule chamber (11) is situated under the mid-plate (3).

14. The inhalation device according to claim 1, wherein said device comprises a capsule chamber (11) and guide rails (11a,11b) extending towards the side part of the capsule chamber (11) through which the at least one needle (12b, 12c) moves to pierce the capsule.

15. The inhalation device according to claim 1, wherein the at least one needle (12b, 12c) is held by a needle holder (12).
