A fluid dispenser device including a body and a reservoir, and an opening mechanism. The device includes an inhalation piece and an inhalation trigger system that has a deformable air chamber and a trigger element, such that during inhalation through the inhalation piece, the air chamber is deformed and the trigger element actuates the opening mechanism. The air chamber has a deformable side body; an open first end including a peripheral edge that surrounds an opening forming the inlet of the hollow pouch; and a second end forming the bottom of the hollow pouch. The said second end includes a connection mechanism for connecting the air chamber to the trigger element. The side body is in the form of a bellows having bellows portions arranged axially one after another, the bellows-forming side body has bellows portions having outside and/or inside diameters that are different.

Dry powder inhaler dose counters capable of making a display move swiftly between digits, in contrast to the progressive movement that occurs in simple gearing mechanisms.

A dry powder inhaler (10) having a chamber (26) divided into first and second blister compartments (28, 30) for storing unused and used portions (34, 36) of a blister strip (12) is provided. A moveable dividing wall (32) separates the first and second blister compartments. One or more arcuate supporting surfaces (38, 40, 42) are disposed in either the first and/or the second blister compartments and these surfaces support the used or unused blister strip during successive actuations of the inhaler. Use of the arcuate supporting surfaces facilities compact coils of unused and used portions of blister strip, thereby reducing the size of the chamber required for the inhaler.

The invention relates to an apparatus for nebulizing preferably powdered medicinal formulations, the nebulization being assisted by propellant. According to the invention, the propellant is supplied in pulsed form to the powder cavity (1) containing the formulation, which is attached to the nozzle (3) from which the aerosol is emitted. The apparatus according to the invention provides an increase in the fraction of pulmonary particles in the aerosol leaving the nozzle (3).

Dry powder inhaler dose counters capable of making a display move swiftly between digits, in contrast to the progressive movement that occurs in simple gearing mechanisms.

A dry powder inhaler including a main body, a plurality of individual reservoirs, such as blisters, each containing a single dose of powder, and disposed one behind another on a flexible strip, and an opening mechanism provided for opening an individual reservoir each time the device is actuated. The device includes first a displacement mechanism adapted to displace an individual reservoir to face the opening mechanism before and/or after each actuation, and a second displacement mechanism adapted to displace an individual reservoir against the opening mechanism on each actuation. The first displacement mechanism having an indexer wheel provided with a recess that receives an individual reservoir, the recess defined by a bottom wall and an inner side wall of said indexer wheel, and by an outer side wall formed on a separate adjustment element assembled on the indexer wheel.

A method and device for delivering a pharmaceutical to the airway of a human or animal patient, in one aspect, includes a dose drum formed into a cylinder and including a plurality of dose compartments for containing individual doses. In another aspect, the device may include a reservoir containing a pharmaceutical material in bulk form and a metering recess for metering the pharmaceutical material to form a pharmaceutical dose. Another aspect provides an inhaler with a combined reservoir and dosing chamber configured to contain multiple doses of a pharmaceutical material.

A device outputs portioned medications (M) from individual chambers of a strip arranged one behind the other. The strip includes a base strip and a closure strip and the raised chambers of the strip can be opened by pressing a handle by sharp-edged deflection of the closure strip. In order to simplify the design and for safe operation, a chamber elevation directed toward the mouthpiece opening blocks the actuation of the handle using a blocking element, in which position a chamber arranged in front that has already been freed from the closure strip lies above a fall-through opening, which opening is closed using a flap that can be moved into the opening position by the suction air flow.

The present invention relates to a dry powder inhaler device comprising a body having a guide surface formed on an inner surface thereof, a trigger having a socket with a shape complementing the guide surface, and a spring, characterized by comprising at least one retaining element (8) positioned on the inner surface (1) of the body diagonally across the spring (6) to enable the trigger (5) to perform a stable axial displacement and a mechanism check or quality control to be made as one of the parts of the device (7) body is not closed or assembled yet.

A manifold for a medicament delivery device configured to deliver discrete doses of medicament contained in a plurality of individual compartments spaced along a carrier strip and sealed by a sealing layer to form a medicament carrier, the manifold comprising: at least one opening mechanism comprising a release member arranged to engage between the carrier strip and the sealing layer of a medicament carrier so as to separate the sealing layer from the carrier strip and thereby open a compartment of the medicament carrier as it is advanced into an entrainment position; wherein the release member includes a surface configured to cover the opened compartment when in the entrainment position so as substantially to contain the medicament dose of the opened compartment.
