ABSTRACT:
An inhaler indicator for a dispenser of an inhaled medicament, for example an asthma medicine. An inhaler body is releasably attached to the dispenser and includes a port through which air is drawn when a user of the inhaler inhales preparatory to the administration of a dose of the medicament as is required for proper administration of such medicaments. The flow of air through the port activates an audio or visual signal generator, such as a whistle or a flag, that signals to the user that the user is inhaling and that conditions are appropriate for the administration of the medicament. In an alternative embodiment, an indicator for releasable attachment to a conventional metered dose inhaler includes a passageway through which air is drawn during an inhalation of a user prepatory to the discharge of medicament. A whistle in the passageway creates an audible tone when the conditions are appropriate for discharge of the medicament. The indicator is useful as a trainer of proper technique.
