Inhaler For Powdered, Particularly Medical Substances

Abstract

The invention relates to an inhaler for powdered, particularly medical substances, comprising a suction air duct that extends to a mouthpiece, a reservoir for the substance, and an at least linearly movable dosing chamber for separating a specific amount of the substance from the reservoir and placing the amount into a transfer position in order for the same to be transferred to the suction air flow. In order to further develop a generic inhaler in an advantageous manner, especially so as to charge the dosing chamber by separating a specific amount of substance from the reservoir, the dosing chamber can be rotationally moved in a superimposed fashion while being arranged eccentric to a corresponding axis of rotation.

What is claimed is: 
     
         1 . An inhaler for powdered, particularly medical substances, comprising:
 a suction air channel leading to a mouthpiece,   a storage chamber for the substance; and   a linearly moved dosing chamber for apportioning a specific amount of substance from said storage chamber and bringing said amount of substance into a transfer position, for transfer to said suction air stream,   wherein said dosing chamber is rotationally moved in a superposed manner and is disposed eccentrically in relation to a corresponding axis of rotation (x).   
     
     
         2 . The inhaler according to  claim 1 , wherein said dosing chamber is formed in a plunger slide. 
     
     
         3 . The inhaler according to  claim 1  wherein said plunger slide is formed as a flat part. 
     
     
         4 . The inhaler according to  claim 2 , wherein said dosing chamber comprises a transverse bore running substantially perpendicularly in relation to the corresponding axis of rotation (x). 
     
     
         5 . The inhaler according to  claim 2 , wherein said dosing chamber is disposed on said plunger slide in an orientation where said dosing chamber is situated near a side edge of a wide surface of said plunger slide, and at a spacing from a free end of said plunger slide. 
     
     
         6 . The inhaler according to  claim 1 , wherein said plunger slide interacts outside said storage chamber with a closure plunger, said closure plunger movable in relation to said plunger slide. 
     
     
         7 . The inhaler according to  claim 1 , wherein said closure plunger can be moved into a release position with respect to said dosing chamber in dependence on a reduced suction pressure. 
     
     
         8 . The inhaler according to  claim 1  wherein said suction air channel comprises a radially outward deflection above the dosing chamber. 
     
     
         9 . The inhaler according to  claim 1  wherein said plunger slide itself forms part of a flow deflection. 
     
     
         10 . An inhaler for powdery substances, comprising:
 a mouthpiece and a suction air channel leading to said mouthpiece;   a storage chamber for storing therein the powdery substance;   a movable dosing chamber for apportioning a specific amount of substance from said storage chamber and moving an amount of substance into a ready position for transferring the amount of substance to a suction air stream;   a closure slide element disposed to close off said dosing chamber in the ready position, said closure slide element movable relative to a plunger slide into a dose-release position upon application of a suction underpressure; and   a cup-shaped rotary part, said cup-shaped rotary part configured such that said plunger slide is connected to said rotary part in a rotationally fixed manner.   
     
     
         11 . The inhaler according to  claim 10 ,
 wherein said plunger slide is tapered toward a dipping end thereof.   
     
     
         12 . The inhaler according to  claim 10 , further comprising
 a docking point at a mouthpiece side and formed between said plunger slide and a closure cap,   said docking point formed to disengage upon being overloaded.   
     
     
         13 . The inhaler according to  claim 10 , wherein said rotary part further comprises
 a rotor that provides a loosening effect to said substance stored in said storage chamber when said rotary part is rotated.   
     
     
         14 . The inhaler according to  claim 13 , wherein said rotor comprises
 a first rotor blade and a second rotor blade, said first and said second rotor blades extending from a bottom of said rotary part.   
     
     
         15 . The inhaler according to  claim 14 , wherein said rotor blades are disposed diametrically opposite with respect to a longitudinal center axis x-x of said inhaler. 
     
     
         16 . The inhaler according to  claim 10 , further comprising
 a sealing element provided between said rotary part and said storage chamber.   
     
     
         17 . The inhaler according to  claim 16 , wherein said sealing element comprises a sealing ring,
 said sealing ring inserted between said rotary part and said storage chamber by inserting said sealing ring in an annular groove provided by said rotary part and an annular groove provided by said storage chamber.   
     
     
         18 . The inhaler according to  claim 17  wherein said annular groove of said rotary part comprises a half-rounded cross-sectional configuration.
