Patent ID: 8191555

Claim:
A mobile inhalation unit for the inhalation of active agents, comprising a heating device ( 9 ) and a connection sleeve ( 41 ) which surrounds the heating device ( 9 ) peripherally and is connected or can be connected at one end to an air-permeable active agent depot ( 43 ), wherein at least one flow passage ( 45 ) is configured between the connection sleeve ( 41 ) and the heating device ( 9 ), wherein the heating device ( 9 ) has a heating wire configured as a heating spiral ( 15 ) and having two connector ends ( 23 , 31 ) for the supply of electrical energy, and wherein the heating device ( 9 ) has a thermal reservoir ( 13 , 17 ) for the heating of air which flows along the thermal reservoir, with the thermal reservoir being able to be heated by means of the heating wire, wherein the heating wire ( 15 ) has a temperature coefficient of at least 0.001 K −1 , wherein a cylindrical hollow outer part ( 17 ) of the thermal reservoir is arranged outside the heating spiral and a cylindrical hollow inner part ( 13 ) of the thermal reservoir is arranged inside the heating spiral, said inner part being separate from said outer part, and wherein air sucked in by a user through the at least one flow passage ( 45 ) flows along the total length of the outer part ( 17 ) of the thermal reservoir.
