Abstract
The invention relates to a dry powder inhaler, having a base housing, having a capsule receptacle for a capsule containing dry powder, having at least one needle- or blade-like opening means, movably arranged in relation to the base housing, for opening the capsule, and having a mouthpiece, through which the dry powder from an opened capsule can be inhaled. The invention is distinguished in that the opening means are fastened on the mouthpiece, and that the mouthpiece can be moved in respect to the base housing out of a normal position into an opening position which opens the capsule.
Claims18
A dry powder inhaler for a capsule containing dry powder, the inhaler comprising:
- a base housing;
- a mouthpiece, through which the dry powder can be inhaled from an opened capsule, wherein said mouthpiece can be moved relative to said base housing from a normal mouthpiece position into an opening mouthpiece position to open the capsule;
- at least one needle- or blade-like opening means fastened to said mouthpiece to open the capsule when said mouthpiece is moved into said opening mouthpiece position;
- and a pivoting element cooperating with said base housing on a side thereof facing away from said mouthpiece, said pivoting element comprising or supporting a capsule receptacle, said pivoting element structured to pivot relative to said base housing about a pivot axis extending perpendicularly with respect to a center longitudinal axis of said mouthpiece or of said base housing, wherein, in a closed non-pivoted normal pivoting element position, the pivoting element is substantially flush with an exterior of said base housing, at least portions of said pivoting element pivoting out of said base housing for insertion of the capsule into said capsule receptacle, said inhaler further comprising a spring element disposed between said base housing and said mouthpiece to maintain said mouthpiece under prestress in said normal mouthpiece position.
