Embodiment Construction

[0090] A preferred embodiment of the inhalation device is shown in the accompanying drawings Figures 1 to 10 middle. A preferred embodiment of the capsule box is shown in Figures 11 to 17 middle.

[0091] The inhalation device comprises a lower body 1 and a mouthpiece 3 connected to the lower body by means of a pivot 30 around which the mouthpiece 3 is rotatable. The pivot is also used to fix the mouthpiece 3, the lower body 1, the link actuator 4 and the main body cover 8 together. The lower body comprises a capsule case 2 comprising a chamber 14 adapted to contain a medicament-containing capsule, such as a dry powder medicament-containing capsule. In use, the capsule is placed into this chamber 14 .

[0092] The inhalation device comprises a piercing pin 7 located in the lower body 1 and connected to the mouthpiece 3 via a link 5 and a link actuator 4 . Pierce pin 7 can be at figure 1 and 3 shown in the retracted position and figure 2Move between the extended pier...

Abstract

An inhaler (1) device for inhalation of a medicament from a pierceable capsule (10) comprises a housing (2) for receiving a medicament, capsule, closure means (3) for closing the housing, said closure means being moveable relative to the housing; piercing means (7) suitable for piercing a medicament capsule; wherein movement of the closure means relative to the housing causes movement of the piercing means, and wherein the device comprises an air inlet (71) and an air outlet (72) defining an inhalation passage therebetween, the passage comprising one or more vents (70).

Description

technical field [0001] The present invention relates to an inhalation device for inhaling medicaments and a cartridge for such medicaments. Background technique [0002] Dry powder inhalation (DPI) devices are typically used to inhale powder medications from capsules. DPI devices can be single-dose or multi-dose. In single-dose or multiple-unit-dose DPI formulations, the drug is prepackaged in capsules or wrappers. Container DPI formulations include devices that include at least a container and a metering chamber to administer precise doses of drug. [0003] Medication cassettes, in particular those used in inhalation devices known from the prior art, are used to contain and hold granular or powdery or volatile medicaments, or capsules for containing powdered or volatile medicaments. The structure of the box is such that the drug or capsule located in the chamber is rotated or moved up and down by the air flowing through the chamber, thereby spreading the powdered drug in...
