Problems solved by technology

This has the disadvantage that it is difficult to manage the force applied to ensure full opening without risking opening the next reservoir, especially if the opening member should be actuated by suction
When operating these devices, to open the capsule and release the powder, or to empty an empty capsule after inhalation, the user's fingers often come into contact with the mouthpiece, which presents a risk of infection

Embodiment Construction

[0034] Figure 1 to Figure 12A first embodiment of the present invention is described. In this first embodiment, the inhaler 100 comprises a hollow body 110 comprising an upper opening and a lower opening. The upper opening is at least partially closed by a plate part 120 fixed to said body, while the lower opening is closed by a closing element, such as a shutter 150 , pivotally mounted on said body 110 . Inserted below the plate body part 120 is a sliding mechanism 140 provided with teeth. Advantageously, the plate body part 120 includes a guide member, such as a guide rail 129, which cooperates with the protruding body 149 of the sliding mechanism 140 to guide the translational movement of the sliding mechanism. A pivoting cover 130 is assembled over the plate portion 120 . The cap 130 includes a dispensing aperture 131, preferably formed at a mouthpiece around which the user surrounds his mouth for inhalation. Therefore, as especially in figure 1 As can be seen above,...

Abstract

Dry powder inhaler (100; 200), having a body (110; 210) containing a dispersion chamber (111; 211), a dispensing orifice (131; 231) through which the user inhales, and a loading opening (121; 220) receiving a capsule (10) containing a dose of dry powder to be inhaled, said loading opening leading into said dispersion chamber, the user inserting a capsule into said loading opening before each use of the inhaler, the inhaler having at least one movable part (130; 260) that can move with respect to said body between a first end position and a second end position, the dispersion chamber (111; 211) having an opening and a closure element (150; 250) for said opening, said closure element being movable between a closing position, in which it closes said opening, and an opening position, in which it opens said opening, said closure element being moved between said opening and closing positions when said at least one movable part (130; 260) is moved between the end positions thereof.

Description

technical field [0001] The invention relates to a dry powder inhaler. Background technique [0002] Inhalers are well known in the art. It exists in different types. The first type of inhaler contains a reservoir that accepts multiple powder doses, the inhaler is equipped with a metering unit that allows a powder dose to be separated from the reservoir for each actuation Taken to a discharge channel for dispensing to users. Another type of inhaler consists in arranging doses of powder in separate pre-dose reservoirs and then opening one of these reservoirs each time the inhaler is actuated. This implementation ensures a good tightness of the powder, since each powder dose is not opened until the moment it is expelled. To implement these individual reservoirs, variants have been proposed, such as an elongated strip of blisters or blisters arranged on a circular rotating disk. All above-mentioned types and existing inhalers have advantages and disadvantages associated wit...
