Abstract

An inhalation device includes: a chamber for intermediate storage of an aerosol, a first connection for a nebuliser that produces the aerosol, a second connection on a patient side for delivering the aerosol, and a third connection for breathable air, where the chamber is fluidically connected in a valve-free manner on an inlet side to the first connection when the nebuliser is attached, and the chamber is connected to the third connection in parallel on the inlet side via an inlet valve so that the breathable air from the third connection flows into the chamber.

First claim

I claim:

1. An inhalation device ( 32 ), comprising:
a chamber ( 38 ) for intermediate storage of an aerosol ( 14 ),
a first connection ( 33 ) for a nebuliser ( 1 ) that produces the aerosol ( 14 ),
a second connection ( 34 ) on a patient side for delivering the aerosol ( 14 ), and
a third connection ( 35 ) for breathable air,
wherein:
the chamber ( 38 ) is fluidically connected in a valve-free manner on an inlet side to the first connection ( 33 ) when the nebuliser ( 1 ) is attached,
the chamber ( 38 ) is connected to the third connection ( 35 ) in parallel on the inlet side via an inlet valve ( 40 ) so that the breathable air from the third connection( 35 ) flows into the chamber ( 38 ), and
the second connection ( 34 ) is connected to the third connection ( 35 ) via an outlet valve ( 45 ) parallel to the chamber ( 38 ), so that the breathable air flows from the second connection ( 34 ) past the chamber ( 38 ) through the outlet valve ( 45 ) to the third connection ( 35 ).

2. The inhalation device according to claim 1 , wherein the chamber ( 38 ) comprises on the outlet side a plurality of outlet openings ( 44 ) arranged at least substantially in an annular configuration.

3. The inhalation device according to claim 1 , wherein the chamber ( 38 ) is fluidically connected to the second connection ( 34 ) on an outlet side in valve-free manner.

4. The inhalation device according to claim 1 , wherein the inlet valve ( 40 ) is a one-way or non-return valve.

5. The inhalation device according to claim 1 , wherein the outlet valve ( 45 ) is a one-way or non-return valve.

6. The inhalation device according to claim 1 , wherein the inhalation device ( 32 ) comprises an intermediate or annular chamber which allows the breathable air to flow from the second connection ( 34 ) through the outlet valve ( 45 ) parallel to the chamber ( 38 ) to the third connection ( 35 ), and the intermediate or annular chamber is formed between the chamber ( 38 ) or a wall that forms the chamber ( 38 ), on the one hand, and a housing ( 39 ) of the inhalation device ( 32 ), on the other hand.

7. The inhalation device according to claim 1 , wherein the outlet valve ( 45 ) comprises a plurality of valve openings ( 46 ).

8. The inhalation device according to claim 7 , wherein the plurality of valve openings ( 46 ) are arranged in a ring around a periphery of the intermediate chamber or annular chamber, wherein the plurality of valve openings ( 46 ) is closed off by one or more separate valve elements ( 47 ).

9. The inhalation device according to claim 1 , wherein the second connection ( 34 ) is embodied as a mouthpiece ( 13 ) or for connection of a tube ( 29 ).

10. The inhalation device according to claim 1 , wherein the third connection ( 35 ) is configured for connection to a ventilator.

11. The inhalation device according to claim 1 , wherein the first connection ( 33 ) of the inhalation device ( 32 ) is connected or connectable to an adapter ( 23 ) having a first connection ( 24 ) for connection in a substantially leak-tight manner to a projection ( 37 ) that holds or surrounds an expulsion nozzle ( 12 ) of the nebuliser ( 1 ).

12. The inhalation device according to claim 11 , wherein the adapter ( 23 ) comprises a locking valve ( 31 ) which necessarily opens when the adapter ( 23 ) is connected to the nebuliser ( 1 ) and closes when the adapter ( 23 ) is separated from the nebuliser ( 1 ).

13. A nebuliser having an inhalation device ( 32 ) according to claim 1 .

14. An inhalation device ( 32 ), comprising:
a chamber ( 38 ) for intermediate storage of an aerosol ( 14 ),
a first connection ( 33 ) for a nebuliser ( 1 ) that produces the aerosol ( 14 ),
a second connection ( 34 ) on a patient side for delivering the aerosol ( 14 ), and
a third connection ( 35 ) for breathable air,
wherein:
the chamber ( 38 ) is fluidically connected in a valve-free manner on an inlet side to the first connection ( 33 ) when the nebuliser ( 1 ) is attached,
the chamber ( 38 ) is connected to the third connection ( 35 ) in parallel on the inlet side via an inlet valve ( 40 ) so that the breathable air from the third connection ( 35 ) flows into the chamber ( 38 ), and
the chamber ( 38 ) comprises on the outlet side a plurality of outlet openings ( 44 ) arranged at least substantially in an annular configuration.
