Problems solved by technology

This has the disadvantage that it is difficult to manage the force applied to ensure a complete opening without risking opening the next reservoir, especially if the opening member should be actuated by suction
When manipulating these devices, to open the capsule and release the powder, or to expel an empty capsule after inhalation, the user's fingers typically touch the mouthpiece, which poses a risk of contamination
Also, to expel an empty capsule, the device generally needs to be disassembled, which exposes the interior of the device to any external contamination which can later be transmitted to the user upon future inhalation

Embodiment Construction

[0030] Figure 1 to 12 shows the first embodiment of the present invention. In this first embodiment, the inhaler 100 has a hollow body 110 with an upper opening and a lower opening. The upper opening is at least partially closed by a plate portion 120 fixed to said body and the lower opening is closed by a closing element, such as a shutter 150 , pivotally mounted on said body 110 . Underneath the plate portion 120 there is interposed a sliding mechanism 140 equipped with a set of teeth. Advantageously, the plate portion 120 has guides such as rails 129 cooperating with projections 149 of the slide mechanism 140 to guide said slide mechanism in translational movement. A pivot cover 130 is fitted over the plate portion 120 . The mask 130 has a dispensing hole 131, preferably formed at the mouthpiece around which the user's mouth is for inhalation. Thus, especially if figure 1 As can be seen above, the device according to this first embodiment consists of five main compon...

Abstract

A dry-powder inhaler including a body containing a dispersion chamber; a dispenser orifice through which the user inhales; a loading opening that receives a capsule containing a dose of dry powder for inhaling; and at least one movable portion that moves relative to the body between a first end position and a second end position; the dispersion chamber containing at least a portion of an empty capsule at the moment of inhalation, the at least one capsule portion swirling in the dispersion chamber during inhalation so as to disperse and / or break up the powder.

Description

technical field [0001] The present invention relates to dry powder inhalers. Background technique [0002] Inhalers are well known in the art. There are various different kinds of inhalers. The first type of inhaler contains a reservoir for receiving multiple doses of dry powder, said inhaler is equipped with a metering device that allows a dose of the dry powder to be dispensed from the reservoir each time it is actuated so that it Transfer to the discharge channel for distribution to the user. Another type of inhaler consists in arranging dry powder in separate reservoirs of predetermined doses and then opening one of these reservoirs each time the inhaler is actuated. This embodiment ensures better sealing of the dry powder, since each dose is only opened when it is expelled. Various variants have been proposed for implementing these individual reservoirs, such as an elongated strip of blisters or blisters arranged on a circular carousel. All the above-mentioned exis...
