Embodiment Construction

[0085] figure 1 is an exploded view of an inhaler 2 according to at least one exemplary embodiment of the present invention. The inhaler 2 comprises a dose-dispensing assembly 4 of generally disc construction, an upper housing part 6 , a lower housing part 8 , an outlet (here shown in the form of an mouthpiece 10 ) and an outlet cap 12 .

[0086] The dose-dispensing assembly 4 comprises a circular base 14 with a plurality of chambers 16 arranged sequentially along the circular extension of the base. The chamber 16 may be provided with a drug, for example in dry powder form, and sealed by the foil portion 18, thus providing a sealed compartment. The foil portion 18 is part of one common foil or provided as a separate piece. In the example shown, perforations are provided to define the foil portion 18 and facilitate separation from the base 14 . On top of each chamber 16 a respective separating element 20 is connected to the upper side of the foil part 18 . The separating e...

Abstract

The present invention relates to an inhaler, comprising a base having at least one air-tight, foil-sealed cavity containing medicament. An actuator is engagable with a separating element attached to the foil, the actuator having an energized position in which it is biased towards an unloaded position so as to cause the separating element and attached foil to be moved away from the cavity. A latchhas a first position, in which it latches the actuator in said energized position, wherein the latch is at least partly arranged in a flow path such that an inhalation flow through the flow path affects the latch to move from the first position to the second position. The invention also relates to a method of dispensing a medicament from a sealed cavity inside an inhaler.

Description

technical field [0001] The present invention relates to an inhaler comprising a base having at least one sealed chamber containing a medicament. The invention also relates to a method of dispensing a medicament from a sealed chamber within an inhaler. Background technique [0002] There are different types of inhalers on the market. A pressurized Metered Dose Inhaler (pMDI) delivers a fixed dose of a substance in aerosol form. Powder inhalers typically release a dose of powdered substance entrained in the air stream. In a powder inhaler, the powder may be provided in a bulk container of the inhaler from which doses of powder are metered for dispensing. As an alternative to bulky containers, powder inhalers may comprise a single compartment or multiple compartments for containing one or more discrete doses of powdered substance. Such compartments may take the form of sealed blisters in blister packs, chamber-containing strips attached to sealing strips, or other suitable ...
