DEVICES AND A SYSTEM FOR DETECTION AND ANALYSIS OF INHALER USE

Devices, methods and a system for detection and analysis of inhaler use, in particular breath detection modules and inhaler device counters. An electronic inhaler counter device (100) comprises a rocker arm (102) comprising a proximal end (110) providing a pivot (104) and a distal end (112) providing a head (114), a return spring (108) coupled to the rocker arm pivot, and a count switch (106), wherein, in response to a first selected degree of linear actuation motion, the rocker arm is arranged to perform a first rocker movement and engage the count switch with the rocker head; and in response to further linear actuation motion, the spring is engaged to enable the rocker arm to perform a second rocker movement, such to facilitate over travel. An inhaler breath detection module coupled to an airpath of the inhaler comprises a sensing means configured to provide signals indicative of a change in parameter in the inhaler airpath as a function of time caused by an inhalation breath, and a controller configured to determine the presence of breath, based on a change in parameter in the inhaler airpath as a function of time.
