Abstract
The invention provides an inhalation device using an electrically driven vibratory element for releasing a drug dose into a flow channel, and a controller for activating/deactivating the vibratory element. A sensor arrangement is able to differentiate between inhalation flow and exhalation flow through the flow channel, to assist in forming a model of the breathing pattern of the user. The device can detect reliably inhalation flow patterns from patients of all ages.
