Abstract:
1. A device for dispensing powdered medicament by inhalation, comprising a medicament container for receiving a plurality of medicament doses, the wall of said container having an elongate slot into which a rotatable metering disc is secured by a disc axis, the metering disc extending into the interior of the medicament container; an air channel through which air can be drawn via a mouthpiece; in the metering disc one or more peripherally located dosing grooves, which extend axially through the metering disc, capable of receiving a metered dose of medicament while being inside the medicament container and capable of transferring a metered dose of medicament from the medicament container to the air channel; the air channel comprising a conduit across which the metering disc is slidably fitted such that for inhalation a dosing groove containing a metered dose of medicament can be brought in register with said conduit; and the metering disc being in sliding contact with a supporting wall extending to the level of the conduit so as to prevent falling of a metered dose of med icament out of the dosing groove throughout its transfer from the medicament container to the air channel, whereby a stream of inhaled air discharges a dose of medicament directly from the dosing groove.
