Abstract

An inhalation device for a powdery medium includes a housing having at least one medium reservoir and an outlet channel, in which a first end of the outlet channel opens out in the area of the medium reservoir and a second end is designed to lie flush on a respiration opening of a user, such that the medium stored in the medium reservoir can be inhaled by the user breathing in. A respiration assistance device is provided which can be connected releasably to the housing and from which an air stream assisting the inhalation can be delivered to the housing by a manual actuation.

Claims

1. Inhalation device for an in particular powdery medium (30), with a housing (10) having

at least one medium reservoir (24) and

an outlet channel (42),

in which a first end (42a) of the outlet channel (42) opens out in the area of the medium reservoir (24) and a second end (42b) is designed to lie flush on a respiration opening of a user, such that the medium (30) stored in the medium reservoir (24) can be inhaled by the user breathing in,

characterized by

a respiration assistance device (60) which can be connected releasably to the housing (10) and from which an air stream assisting the inhalation can be delivered to the housing (10) by means of a manual actuation.

2. Inhalation device according to claim 1, characterized in that the respiration assistance device (60) is designed for a manual actuation in a direction of actuation (4) which is parallel to a main direction of orientation (6) of the outlet channel (42).

3. Inhalation device according to claim 1, characterized in that the respiration assistance device (60) has a compression chamber (62) whose volume can be mechanically reduced directly by the manual actuation.

4. Inhalation device according to claim 3, characterized in that the respiration assistance device (60) has a bellows (62).

5. Inhalation device according to claim 1, characterized in that a finger support surface (44) is provided on a side of the housing (10) directed away from the respiration assistance device (60).

6. Inhalation device according to claim 1, characterized in that the respiration assistance device (60) and the housing (10) are designed in a contact area in such a way that a force applied by the manual actuation leads to portions (48, 64) arranged on the housing and on the respiration assistance device being pressed tightly onto each other in the contact area.

7. Inhalation device according to claim 1, characterized in that, in a contact area, the respiration assistance device (60) and the housing (10) have sealing and/or securing means (26, 64, 66) acting with a force fit and/or a form fit.

8. Inhalation device according to claim 7, characterized in that the securing means comprise a push-on cone (26) on the housing and a push-on portion (64, 66) on the respiration assistance device.

9. Inhalation device according to claim 1, characterized in that the housing (10) is designed in several parts, in particular in two parts, the at least one medium reservoir (24) being designed in a first housing part (20), and the outlet channel (42) being designed on a second housing part (40), and in that a circumferential contact area between the respiration assistance device (60) and the second housing part (40) is designed as a contact area that is airtight to the outside during operation.

10. Inhalation device according to claim 8, characterized in that releasable activation-blocking means (50) are provided on the housing (10) and, when the housing (10) is joined to the respiration assistance device (60), prevent the first housing part (20) and the second housing part (40) from moving relative to each other.

11. Inhalation device according to claim 1, characterized in that the housing is produced by injection molding and/or the bellows is produced by injection blow molding.
