SYSTEM AND METHOD FOR MONITORING USE OF A DEVICE

摘要

The invention provides a system and method suitable for monitoring user technique of an inhaler device configured for delivery of a medicament, said system comprising a microphone adapted for sensing sound made during operation of the inhaler device; and processing circuitry operable to process a data signal obtained from the microphone, wherein said data signal comprises acoustic information sensed. The processing circuitry is adapted to determine inhalation and exhalation breath characteristics that occur during use, by analysing the temporal and spectral components of the acoustic information sensed and processed to differentiate between an inhalation and an exhalation, based on both the temporal and spectral components. This information can be processed to determine user technique adherence to inhaler or respiratory device protocol. The analysis of temporal and spectral components can determine the impact of user technique errors on the quantity and the deposition of medicament delivered into the user's airways.
