IMPROVED INHALATION METHOD AND APPARATUS

摘要

Signals may be generated in a drug delivering apparatus through which a person inhales to generate a inhaled airstream to signal to the person to cease inhalation after a pre-set period of time has elapsed from detection of the commencement breathing by that person. The pre-set period of time for subsequent inhalations is adjusted depending on the time the person takes to stop inhaling after being signalled.
