ABSTRACT:
An apparatus for training a person to use an inhaler comprises such an inhaler connected to a processing device. The inhaler comprises means for detecting when the inhaler is activated for making a dose of a drug available for inhalation and means for detecting the inhalation flow through the inhaler. The processing device comprises means for indicating to the patient how the inhaler is to be activated in order to make a dose available and means for urging the patient to perform such an activation. The latter means are activated when the apparatus is turned on and deactivated when a proper activation of the inhaler is detected. The processing device further comprises means for urging the patient to inhale through the inhaler. These means are activated when a proper activation of the inhaler is detected and deactivated when an inhalation flow is detected. The measured inhalation flow is indicated by indication means on the processing device.
A method for training a person to use an inhaler is also disclosed.
