FLOW REGULATING INHALER DEVICE
First Claim
1. An inhaler device for delivering to a user at least one drug substance emitted from a dose cartridge, the inhaler device comprising:
- a holder configured to hold a dose cartridge at a dose cartridge position in which said at least one drug substance emitted from said dose cartridge enters a carrier airflow;
a first conduit for conducting said carrier airflow from said dose cartridge position to an opening through which the user inhales;
at least one valve located between said dose cartridge position and said opening and configured to affect said carrier airflow;
at least one sensor positioned and configured for detecting at least one parameter indicating a rate of said carrier airflow; and
a controller configured to control, by affecting said at least one valve, a rate of said carrier airflow within said dose cartridge based on said at least one parameter obtained by said sensor.

Abstract
Some embodiments of the invention relate to an inhaler device for pulmonary delivery of at least one substance from a drug dose cartridge to an inhaling user, comprising: 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.
