Patent ID: 8733345

Claim:
An inhalation device ( 10 ; 110 ; 210 ; 310 ) for the inhalation administration of an inhalation mixture of air and at least one additive material, comprising: a generally cylindrical outside wall ( 220 ) having a proximal end and a distal end; a mouthpiece ( 82 ; 182 ; 282 ) disposed at the proximal end of the generally cylindrical outside wall ( 220 ); a heating unit ( 50 ; 350 ) for heating the air and the additive material disposed at the distal end within the generally cylindrical outside wall; and an inhalation mixture generator ( 70 ; 170 ; 270 ; 370 ) disposed within the generally cylindrical outside wall between the mouthpiece and the heating unit, the inhalation mixture generator having an air inlet opening ( 72 ; 272 ) towards the heating unit and an air outlet opening towards the mouthpiece ( 82 ; 182 ; 282 ), wherein the heating unit ( 50 ; 350 ) comprises a fuel storage ( 52 ; 152 ; 252 ) spatially separated from the inhalation mixture generator, the fuel storage configured to receive a thermally combustible solid or liquid fuel ( 258 ), and a combustion chamber ( 56 ; 156 ; 256 ) configured to form a flame to combust the fuel, and wherein micro openings ( 24 ; 124 ; 224 ) are provided in the generally cylindrical outside wall around the combustion chamber to supply oxygen to the flame and to protect the flame from wind gusts, wherein the micro openings at least partially overlap the flame.
