air which can be controlled by heater 166 block 140 is located directly over heating zone 70 and creates a heating vaporization mixing zone prior to commencing aerosol generation slide 78 is in the downstream position slide 78 with its contents is then drawn upstream into this heating vaporization mixing zone 70 as energy is applied to foil 64 through the inductive heater system described in detail below the device of the present invention is optionally equipped with an annunciating device one of the many functions for the annunciating device is to alert the operator of the device that a compound is not being vaporized or is being improperly vaporized the annunciating device can also be used to alert the operator that the gas flow rate is outside a desired range fig6 is a schematic diagram illustrating a third example of a hand held aerosolization device 180 of the present invention as shown device 180 includes many of the components of device 150 discussed above and additionally includes an annunciating device 170 during the use of device 180 in which the patient 39 s inhalation rate controls the airflow rate a signal from annunciating device 170 would alert the patient to adjust the inhalation rate to the desired range in this case controller 160 would be connected to annunciating device 170 to send the necessary signal that the flow rate was.
