Problems solved by technology

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 Figs. 9 to 16, the dose indicator may simultaneously be a locking mechanism as described in the dr...

Abstract

A dry powder medicament inhaler (100) for metering an inhaled dry powder medicament is provided. The inhaler (100) comprises at least one inlet (101) and at least one outlet (102), wherein the communication between the at least one inlet (101) and the at least one outlet (102) comprises at least mixing and deaggregation The active chamber (106) and at least two dose communications (107) between said at least one inlet (101) and said chamber (106). The inhaler (100) further comprises a dosing mechanism (104, 108) for disposing at least one dose of medicament between the inlet (101) and the chamber (106) such that the at least one dose is It can be delivered to the outlet (102) through the communication piece (107) during inhalation. The inhaler (100) may include a locking mechanism (200), wherein when the dose mechanism (104, 108) is moved from the dose collecting position to the dose administering position, the locking mechanism (200) moves from an unlocked position to a locked position to prevent Measure any other doses before resetting the locking mechanism. Instead of the locking mechanism (200), the inhaler may include a dose indicator (300) or a weight mechanism (420). The inhaler (100) may also include a combination of locking mechanism (200), dose indicator (300) and weight 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 ...
