Patent attributes
Some embodiments are directed to a device for monitoring patient usage of a medicament inhaler, being adapted to deliver doses of medicament, and including parts which move during the dispensing of a dose of medicament. The device includes a housing, for releasable attachment to the medicament inhaler, and an optical dose counter associated with said housing, being adapted to determine when a dose of medicament has been dispensed by transmitting optical signals through the medicament inhaler. The device is attachable to the medicament inhaler, and is subsequently operable without any modifications being required to be made to the medicament inhaler. The device may also include an electronic control module which is in communication with the optical dose counter, the electronic control module being adapted to monitor and/or store data relating to patient usage of the medicament inhaler.
