Abstract: An adherence-monitoring and tracking device captures usage of a metered dose inhaler (MDI). The device includes an enclosure for enclosing a metered dose inhaler (MDI), and an electro-mechanical system forming a part of enclosure to sense and log the operation of the MDI. The electro-mechanical system includes at-least one transducer to capture one or more parameters pertaining to an operation of the MDI by the user. A microcontroller processes the captured parameters, and an output-unit renders data pertaining to operation of the MDI.

Abstract: A breath-actuated inhaler includes a motion-generator configured to render motion upon actuation by a user. An arrangement transforms the generated motion to enable a canister at undergoing translation-motion. A metering-valve is operably connected to the canister to cause a metered-release of the canister's contents as a spray, based upon the translation-motion.
