Abstract

A nebulizer for a fluid, particularly for medical aerosol treatment is proposed. To allow easier operation and confer improved operational reliability a sealed container holding the fluid is already arranged in the nebulizer when it is supplied and the nebulizer is constructed so that the container is opened inside the nebulizer before or during the first use of the nebulizer. For this purpose, a transportation lock is provided for the sealed container which, in the delivery state, is in engagement with the sealed container in a manner preventing the sealed container from moving axially in the nebulizer.

First claim

What is claimed is:

1. Nebulizer for a fluid comprising:
a housing
a container containing multiple doses of the fluid, said container being sealed off in a delivery state and disposed in the housing,
a container opening device inside the housing which is adapted to open the container which is sealed off before or during a first use of the nebulizer, and
a transportation lock for the container which, in the delivery state, is in engagement with the sealed container in a manner preventing the container from moving axially in the nebulizer in the delivery state and preventing opening of the container by the container opening device in the delivery state,
wherein the transportation lock is releasable before or during a first use of the nebulizer,
wherein the transportation lock comprises gripper arms for securing the container in the delivery state, and
wherein the gripper arms are flexibly deflectable to open the transportation lock by axial movement of the container.

2. Nebulizer according to claim 1 , wherein the container is movable in a stroke action, during at least one of conveying of the fluid, pressure generation and nebulization after disengagement of said transportation lock.

3. Nebulizer according to claim 1 , wherein the gripper arms are distributed around the circumference of the container.

4. Nebulizer according to claim 1 , wherein an inner part is provided for deflecting the gripper arms by axial engagement.

5. Nebulizer according to claim 1 , wherein the gripper arms are secured in the delivery state against flexing or deflection.

6. Nebulizer according to claim 5 , wherein a securing element is provided which secures the transportation lock against opening, the securing element being axially moveable to open the transportation lock.

7. Nebulizer according to claim 1 , wherein the transportation lock is arranged completely inside the housing.

8. Nebulizer according to claim 1 , wherein the gripper arms of the transportation lock engage on a base of the container or a transition of the container to the base of the container.

9. Nebulizer according to claim 1 , wherein the transportation lock acts directly on the container.

10. Nebulizer according to claim 1 , wherein the container is moveable in a stroke action relative to the housing after disengagement of said transportation lock.

11. Nebulizer according to claim 1 , wherein the container is moveable in a stroke action inside the housing after disengagement of said transportation lock.

12. Nebulizer according to claim 1 , wherein the housing comprises a housing part and wherein the transportation lock is releasable by axially pushing the housing part onto the nebulizer.

13. Nebulizer according to claim 1 , wherein the housing comprises a housing part and wherein a removable securing member is provided for preventing, in the delivery state, axial pushing of the housing part so as to open the container.

14. Nebulizer according to claim 1 , wherein the transportation lock comprises arms for holding the container in the delivery state, the arms being circumferentially arranged around the container.

15. Nebulizer according to claim 1 , wherein the transportation lock circumferentially surrounds the container.

16. Nebulizer according to claim 1 , wherein the transportation lock is releasable by completely closing the housing.

17. Nebulizer according to claim 1 , wherein the transportation lock is released during opening the container.

18. Nebulizer according to claim 1 , wherein the transportation lock is released after opening the container.

19. Nebulizer according to claim 1 , wherein the housing is partially closed in the delivery state of the nebulizer.

20. Nebulizer according to claim 1 , wherein the container opening device comprises means for opening the container by piercing.
