Embodiment Construction

[0025] FIG. 1 shows a very schematic view of a proposed inhaler 1 according to a first embodiment, ie in a cutaway or open state without a cap or cover.

[0026] The inhaler 1 is used for expelling a preferably powdered inhalation formulation from a blister strip 2 with a plurality of blister pockets 3 each directly containing a dose of the inhalation formulation, in particular in loose form. A powder 4 forming an inhalation formulation is represented in FIG. 1 , for example in a blister pack 3 . For inhalation, and especially during inhalation, preferably a dose of the inhalation formulation is removed from the blister 3 in each case.

[0027] The bubble stick 2 is preferably formed in the form of a strip. Preferably, the blister strip 2 is configured with ends, ie not formed as a ring or closed strip.

[0028] The inhaler 1 preferably has a reservoir 5 for not yet used blister sticks 2 with not yet emptied blister packs 3 . In particular, the blister strip 3 is rolled or ...

Abstract

An inhaler is proposed for dispensing a powdered inhalation formulation from a blister strip with a multiplicity of blister pockets. The used part of the blister strip with emptied blister pockets is wound up by a watch spring or is pushed into a helical channel. A simple structure is thus permitted, wherein the used blister strip is separtaed from the still unused part.

Description

technical field [0001] The invention relates to an inhaler according to the preamble of one of the independent claims. [0002] The invention relates to an inhaler for expelling powdered inhalation formulations (Inhalationsformulierung) from a blister strip with a plurality of blister packs (Blistertaschen) each containing a dose of the inhalation formulation. Background technique [0003] GB 2 407 042 A discloses an inhaler with a wrapped blister strip. During inhalation, a dose of the inhalation formulation of the blister pack is removed in each case and the blister pack is thus emptied. This can be achieved, for example, during inhalation by the patient by generating an air flow through a previously pierced or otherwise opened blister so that the inhalation formulation located in the blister mixes with the air and Expelled in the desired manner. Empty blister bags are discharged separately and must be disposed of. [0004] WO 2005 / 037353 A1 discloses a similar inhaler...
