Inhalation device
First Claim
1. Inhalation device comprisinga housing having an air inlet, an air outlet and an airway therebetween;
- a medicament carrier having a substantially planar first face and a plurality of medicament retainers defining openings in said first face, said openings being directed in a common direction and forming a single spiral path arrangement along said first face; and
a mover for moving the medicament carrier relative to the housing so as to bring successive medicament retainers individually into communication with the airway.

Abstract
A medicament cartridge for use in an inhalation device comprising a carrier having a plurality of medicament retainers in a spiral path arrangement. Typically, the carrier is substantially planar. In one embodiment the carrier comprises an elongate carrier storable in a flat spiral configuration and extendable as a helix. There is also provided an inhalation device comprising a housing having an air inlet, an air outlet, an airway therebetween and a medicament carrier having a plurality of medicament retainers in a spiral path arrangement. A mover is provided for moving the medicament carrier relative to the housing so as to bring successive medicament retainers individually into communication with the airway.
