Abstract
A dry-powder inhaler having a body and a mouthpiece provided with a dispensing orifice through which the user inhales, a chamber, a reservoir containing a dose of dry powder to be inhaled and having a lateral outlet opening. The reservoir is disposed in the chamber, the diameter of the reservoir being less than the diameter of the chamber, so that, in the loaded position, the reservoir can move in the chamber. The body has tangential channels adapted to bring a flow of inhalation air tangentially into the chamber, which, during inhalation, generates an orbital movement of the reservoir in the chamber, in the loaded position. The reservoir has an external profile defining an inscribed volume forming an external volume of the reservoir that is greater than the internal volume of the reservoir that contains the powder.
