DRY POWDER INHALER FOR PULMONARY OR NASAL DELIVERY

Abstract

A dry powder inhaler (1) has a chamber (12) for housing a capsule and an inhalation channel (22), the chamber (12) is shaped in order to determine an agitated motion of the capsule in the chamber (12) during an inhalation of a user, the inhaler (1) comprises a capsule-piercing mechanism (30) arranged to pierce a capsule in the chamber (12) and a monitoring system (40) comprising an accelerometer (42) to measure mechanical oscillations determined at least by the agitated motion and by a flow of air through the chamber (12) and/or inhalation channel (22), the accelerometer (42) being arranged on a printed circuit board (48) arranged to transmit the mechanical oscillations from the inhaler body (10) to the accelerometer (42); a detection unit (44) arranged to detect an activation of the capsule-piercing mechanism (30); and an electronic processing unit (46) configured to receive signals from the detection unit (44) and from the accelerometer (42). Reception of a signal from the detection unit (44) triggers processing of signals from the accelerometer (42) by the electronic processing unit (46) in order to generate inhalation data. The monitoring system (40) is integrated in the inhaler body (10) or in a monitoring module (41) that is permanently or detachably attached to the inhaler body (10).
