This abuse can be intentional or unintentional, but in some cases it can cause users to take larger doses than necessary through the inhaler
In other cases, failure to properly handle dose metering may result in users not taking doses at all

Embodiment Construction
[0056] Those skilled in the art will appreciate that the dry powder inhalers of the embodiments described below with reference to the accompanying drawings are substantially the same in their general design, but differ only in locking mechanisms, dose indicators or improper dose prevention mechanisms. However, as will become clearer below, dry powder inhalers may have two or all three of a locking mechanism, a dose indicator, or an improper dose prevention mechanism. For example, in the description of Figures 18 and 19, the improper dose prevention mechanism of the dry powder medicament inhaler may also be a locking mechanism. Furthermore, as will be described in Figures 17 to 24, the improper dose prevention mechanism of the dry powder inhaler may also be a combined indication and locking mechanism. It is also disclosed that in a dry powder inhaler comprising a dose indicator of Figures 9 to 16, the dose indicator may simultaneously be a locking mechanism as described in the ...

A dry powder medicament inhaler (100) for metering an inhalation of dry powdered medicament is provided. The inhaler (100) comprises at least one inlet (101) and at least one outlet (102), wherein a communication between said at least one inlet (101) and said at least one outlet (102) at least comprises a mixing and de-aggregation chamber (106) and at least two dosage communications (107) betweenthe at least one inlet (101) and the chamber (106). The inhaler (100) further comprises a dosage mechanism (104, 108) for arranging at least one dose of a medicament between the inlet (101) and the chamber (106), such that said at least one dose may be delivered upon inhalation at said outlet (102) through said communications (107). The inhaler (100) may comprise a locking mechanism (200) whereinon moving the dosage mechanism (104, 108) from a dose collecting position to a dose administering position the locking mechanism (200) is moved from an unlocked to a locked position preventing the metering of any further doses prior to resetting of the locking mechanism. Instead of a locking mechanism (200), the inhaler may comprise a dosage indicator (300) or a counterweight mechanism (420). Theinhaler (100) may also comprise combinations of a locking mechanism (200), a dosage indicator (300) and a counterweight mechanism (420).
Description
technical field [0001] The present invention relates generally to the field of medicament inhalers, and more particularly to dry powder inhalers. The inhaler may include a locking mechanism such that any pre-metered dose needs to be inhaled before more doses can be administered. Alternatively, the inhaler includes an indicator for determining whether any pre-metered dose has not been inhaled. Alternatively, the inhaler may include a weight mechanism for holding the improper dose prevention mechanism in one position. Background technique [0002] In the pharmaceutical field, inhalers are widely used for the treatment of respiratory and / or other diseases. Large quantities of drugs, preparations and other substances are inhaled into the lungs for rapid absorption by the bloodstream, and the inhaler is used for localized treatment within the lungs. [0003] Inhaled medicines fall into two broad categories, in liquid form, including suspensions, and powders. The selection of ...
