Abstract
An inhaler device for pulmonary delivery of at least one substance from a drug dose cartridge to an inhaling user, including: a first conduit for conducting a carrier airflow to a proximal opening of a mouthpiece for use by the user; a holder configured to position the dose cartridge within the carrier airflow; and a second conduit for conducting a shunting airflow to the mouthpiece without passing through the dose cartridge position. A controller connected to a valve controls a rate of carrier airflow, for example by controlling the shunting airflow, based on a sensor indication of airflow rate and a target airflow profile.
