Abstract
In an aerosol inhaler it is proposed that a thermal sensor 5 be arranged in the region of the atomization nozzle 4, which sensor, following the actuation of an actuating element and the triggering of an inhalation process, undergoes cooling as a result of the expansion of the propellant which then occurs. The actuation and cooling are electronically detected in an electronic module 3. Technical and therapeutic data can be derived from the signal, which data are communicated to the user via the display unit and/or alarm devices and influence the therapy in the desired manner. See FIG. 1.
