Abstract
A powder inhaler comprising a powder container, an air channel, a metering member equipped with a dosing recess, an actuating means for the displacement of the metering member between the filling and the inhalation position, and a closure element for plugging the air channel in a substantially water-proof manner when the metering member is in the filling position and opening the air channel when the metering member is in the inhalation position. When the inhaler is not in use, the closure element prevents moisture and dirt from entering the sensitive parts of the device.
Claims14
A powder inhaler, comprising
- a powder container;
- an air channel through which air can be drawn via a mouthpiece;
- a metering member equipped with a dosing recess, the metering member being movable between a filling position in which the dosing recess can be filled with powder, and an inhalation position, in which the dosing recess, when filled, can be brought into the air channel, wherein a stream of inhaled air can discharge a dose of powder directly from the dosing recess;
- actuating means for the displacement of the metering member between the filling and the inhalation position;
- and
- a closure element adapted to plug the air channel around the metering member in a substantially water-proof manner, so as to protect the air channel around the metering member from moisture, when the metering member is in the filling position, and to open the air channel when the metering member is in the inhalation position,
- wherein operation of the actuating means results in the movement of the metering member as well as the closure element.
