A powder inhaler comprises a medicament container, a rotatable metering disc extending into the interior of the medicament container and an air channel through which air is drawn via a mouthpiece. The metering disc has one or more peripherally located dosing grooves extending axially through the metering disc. The dosing grooves are filled with a metered dose of the medicament while being inside the medicament container and are transferred to the air channel wherein the stream of inhaled air discharges the dose of the medicament directly from the dosing groove.
This application is a U.S. national stage filing of International Application No. PCT/F100/01078, filed on Dec. 7, 2000. This application claims the benefit of priority under 35 U.S.C. .sctn. 119(a) to Finnish patent application Ser. No. 19992620, filed on Dec. 7, 1999.
There is described a medicament delivery device which comprises a medicament reservoir, a medicament delivery passage and a metering member adapted to transfer a measured dose of medicament from the medicament reservoir to the delivery passage characterized in that the device is provided with a moisture proof barrier. The medicament delivery device is especially suited for use as an inhaler. There is therefore also described an inhaler which provides improved airflow for the dispersion of medicament, and a method of treating patients suffering from a respiratory disorder.
There is described a medicament delivery assembly which comprises mouthpiece provided with an air amplifier and a primer source, wherein the mouthpiece and the air amplifier are each is connected to the primer source via an actuatable valve; the air amplifier is also provided with a medicament extraction tube such that when the actuatable valve is opened then the primer source is activated and causes air to flow to the air amplifier. There is also described a method of administering a medicament which comprises the use of such a medicament delivery assembly.
A delivery device, e.g. an inhaler, comprises a rotatable metering member adapted to dispense a measured amount of material, a material delivery passage and a material delivery orifice and at least one actuator member adapted to move the metering member form a material retaining position to a material dispensing position. In a magazine comprising a plurality of metering members, the actuator and metering members may operate in a radial direction. A plurality of rotatable magazines may be utilized in the delivery device. The delivery device may be used to deliver a single or a combination therapy.
