Delivery device
First Claim
1. A delivery device comprising a metering member adapted to dispense a measured amount of material, a rotatable magazine having an axis of rotation, a material delivery passage, a material delivery orifice, and at least one actuator member adapted to act upon said metering member so as to move the metering member from a material retaining position to a material dispensing position wherein the actuator member moves in a substantially radial direction relative to the axis of rotation of said magazine and actuates the metering member in said substantially radial direction, characterised in that said metering member is held in the rotatable magazine when acted upon by said actuator member and is ejected in said substantially radial direction into the material delivery passage when moved to the material dispensing position.

Abstract
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.

- 1. A delivery device comprising a metering member adapted to dispense a measured amount of material, a rotatable magazine having an axis of rotation, a material delivery passage, a material delivery orifice, and at least one actuator member adapted to act upon said metering member so as to move the metering member from a material retaining position to a material dispensing position wherein the actuator member moves in a substantially radial direction relative to the axis of rotation of said magazine and actuates the metering member in said substantially radial direction, characterised in that said metering member is held in the rotatable magazine when acted upon by said actuator member and is ejected in said substantially radial direction into the material delivery passage when moved to the material dispensing position.
- 25. A delivery device comprising a plurality of rotatable metering members adapted to dispense a measured amount of material, said metering members being held in a pair of rotatable magazines, a material delivery passage, a material delivery orifice, and at least one actuator member adapted to move said metering member from a material retaining position to a material dispensing position wherein the actuator member moves in a substantially radial direction and actuates the metering member in said substantially radial direction, and means for engaging a first magazine whilst disengaging a second magazine and which engaging means is moveable from an engaging to a disengaging position and vice versa.

31. A dry powder inhaler comprising a metering member adapted to dispense a measured amount of medicament, a rotatable magazine having an axis of rotation, an inhalation passage, a mouthpiece, and at least one push rod adapted to act upon said metering member so as to move the metering member from a medicament retaining position to a medicament dispensing position wherein the push rod moves in a substantially radial direction relative to the axis of rotation of said magazine and actuates the metering member in said substantially radial direction, characterised in that said metering member is held in the rotatable magazine when acted upon by said actuator member and is ejected in said substantially radial direction into the inhalation passage when moved to the medicament dispensing position.
