Inhaler
An inhaler ( 1 ) is proposed (see FIG. 1 ), for the inhalation of a formulation ( 2 ) from capsules ( 3 ) that each contain one dose of the formulation. The capsules are preferably each emptied in a capsule chamber ( 4 ) by being set in motion by a stream of air flowing through the capsule chamber. The stream of air can be generated by the inhalation of a user or patient and/or can be generated actively generated by the inhaler. For simple handling, the inhaler has a means for, in particular, automatic filling, emptying and/or cleaning of the capsule chamber, if the latter is used more than once. Alternatively, the inhaler has a large number of capsule chambers that each preferably already contain a capsule and re preferably used just once.
1. An inhaler ( 1 ) for the inhalation of a formulation ( 2 ) from capsules ( 3 ), each containing one dose of the formulation ( 2 ), wherein the inhaler ( 1 ) comprises a plurality of capsule chambers ( 4 ) containing respective capsules ( 3 ) in order to empty them during inhalation, wherein each of the capsule chambers ( 4 ) contains a respective one of the capsules ( 3 ), each capsule chamber ( 4 ) and capsule ( 3 ) can be used only once, and the capsule chambers ( 4 ) are arranged in a ring such that the capsule chambers ( 4 ) and the capsules ( 3 ) are aligned radially with respect to a central point.
2. The inhaler according to claim 1 , further comprising a first ring of the capsule chambers ( 4 ) and the capsules ( 3 ) that aligned radially with respect to a first central point, and a second ring of the capsule chambers ( 4 ) and the capsules ( 3 ) that aligned radially with respect to a second central point, wherein the first and second rings are disposed one atop the other.
3. The inhaler according to claim 1 , further comprising at least one annular carrier ( 11 ) within which the capsule chambers ( 4 ) and the capsules ( 3 ) are disposed.
4. The inhaler according to claim 1 , wherein the capsule chambers ( 4 ) include an inlet side and an outlet side, which are closed off by a shared cover ( 12 ) at least on the inlet and/or outlet side, wherein said shared cover ( 12 ) is selected from foil, cover portions ( 12 a ), sleeves and stoppers ( 61 ).
5. The inhaler according to claim 4 , wherein the cover ( 12 ) or cover portions ( 12 a ) is laminated on the carrier ( 11 ).
6. The inhaler according to claim 4 , wherein the cover ( 12 ) or cover portions ( 12 a ) is used to cover respective piercing openings ( 7 ) extending in the respective capsule chambers ( 4 ).
7. The inhaler according to claim 4 , wherein the capsule chambers ( 4 ) can be opened individually through the cover ( 12 ) or cover portions ( 12 a ), wherein said cover ( 12 ) or cover portions ( 12 a ) is pulled off, peeled off, unwound, wound up, pierced or cut.
8. The inhaler according to claim 7 , wherein said cover ( 12 ) or cover portions ( 12 a ) is pulled off, peeled off, unwound, or wound up via at least one roller ( 18 a , 18 b ).
9. The inhaler according to claim 7 , wherein said cover ( 12 ) or cover portions ( 12 a ) is pulled off or peeled via a hook- or shovel-like opening element ( 18 d ).
10. The inhaler according to claim 7 , wherein the capsule chambers ( 4 ) and the capsules ( 3 ) are closed in fluid-tight or gas-tight manner and/or can be opened individually.
11. The inhaler according to claim 1 , wherein the capsule chamber ( 4 ) is of elongate construction and air can flow therethrough in a longitudinal direction thereof in order to empty the respective capsule ( 3 ) and/or expel the respective dose of the formulation ( 2 ).
12. The inhaler according to claim 1 , wherein the capsule chambers ( 4 ) and the capsules ( 3 ) are movable for emptying after the respective capsule ( 3 ) has been opened.
13. The inhaler according to claim 1 , wherein the capsules ( 3 ) can be moved back and forth or set oscillating or vibrating in the respective capsule chamber ( 4 ) in order to empty them.
14. The inhaler according to claim 1 , further comprising an opening device ( 5 ) for opening the respective capsules ( 3 ) laterally, radially axially or at an end face thereof, via piercing the capsule ( 3 ) through the capsule chamber ( 4 ).
15. The inhaler according to claim 14 , wherein the capsule chamber ( 4 ) has at least one re-sealable opening ( 7 ) therethrough for receiving a piercing element ( 6 ) that pierces the capsule ( 3 ), the opening ( 7 ) being re-sealable by means of a cover ( 12 ), a cover portion ( 12 a ), a septum or a spring-loaded or elastic cover element.
16. An inhaler ( 1 ) for the inhalation of a formulation ( 2 ) from capsules ( 3 ), each containing one dose of the formulation ( 2 ), wherein the inhaler ( 1 ) comprises a plurality of capsule chambers ( 4 ) for receiving respective capsules ( 3 ) in order to empty them during inhalation, wherein each of the capsule chambers ( 4 ) contains a respective one of the capsules ( 3 ), each capsule chamber ( 4 ) and capsule ( 3 ) can be used only once, and the capsule chambers ( 4 ) are arranged in a ring such that the capsule chambers ( 4 ) and the capsules ( 3 ) are aligned radially with respect to a central point, wherein the capsule chambers ( 4 ) include an inlet side and an outlet side, which are closed off by a shared cover ( 12 ) at least on the inlet and/or outlet side, wherein said shared cover ( 12 ) is selected from foil, cover portions ( 12 a ), sleeves and stoppers ( 61 ), and wherein the cover ( 12 ) or cover portions ( 12 a ) is laminated on the carrier ( 11 ).
17. An inhaler ( 1 ) for the inhalation of a formulation ( 2 ) from capsules ( 3 ), each containing one dose of the formulation ( 2 ), wherein the inhaler ( 1 ) comprises:
a plurality of capsule chambers ( 4 ) for receiving respective capsules ( 3 ) in order to empty them during inhalation, wherein each of the capsule chambers ( 4 ) contains a respective one of the capsules ( 3 ), each capsule chamber ( 4 ) and capsule ( 3 ) can be used only once, and the capsule chambers ( 4 ) are arranged in a ring such that the capsule chambers ( 4 ) and the capsules ( 3 ) are aligned radially with respect to a central point; and
an opening device ( 5 ) for opening the respective capsules ( 3 ) laterally, radially axially or at an end face thereof, via piercing the capsule ( 3 ) through the capsule chamber ( 4 ).
