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. In some embodiments, 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.
Claims24
An inhaler device for delivery of at least one active substance to an inhaling user, the inhaler device comprising:
- a first conduit for conducting airflow to an opening from which the user inhales;
- a valve positioned and configured to affect flow of ambient air into the first conduit;
- a controller configured to control release of the at least one active substance to be carried by the airflow to the inhaling user, the controller further configured to control the valve to generate a pattern of airflow and active substance delivery modulations, the pattern including:
- (a) delivering the active substance via the airflow followed by substantially stopping active substance delivery and reducing a total rate of airflow to the user for an intermediate period, and then
- (b) increasing the airflow without resuming active substance delivery to a rate or volume sufficient to be sensed by the inhaling user.
A method for delivering to an inhaling user at least one active substance, comprising:
- during a first inhalation period, delivering the at least one active substance via airflow to the inhaling user;
- substantially stopping delivery of the at least one active substance and reducing a total rate of the airflow for an intermediate inhalation period;
- and
- during a final inhalation period, increasing the airflow without resuming active substance delivery to a rate or volume sufficient to be sensed by the inhaling user.
