An inhalation device by which powdered medicaments can be self-administered to a patient comprising a chamber arranged to receive a capsule containing the powdered medicament. At least one air inlet aperture leading into the chamber. A nozzle through which air can be inhaled leads from the chamber. A magazine is slidable and rotatable in the chamber and has a longitudinal capsule loading receptacle arranged so that a capsule inserted therein will have an end portion projecting from the receptacle into the chamber. A knife is fixed in the chamber in such a position that rotation of the magazine with respect to the chamber will cause the projecting portion of a capsule located in the receptacle to engage a cutting edge of the knife thereby to sever the projecting portion of the capsule from the remainder of the capsule. A capsule ejecting member is arranged inside the chamber in a position such that it will enter the capsule loading receptacle when such receptacle has first been registered with the member by appropriate rotation of the magazine with respect to the chamber and then by sliding the magazine with respect to the chamber thereby to eject the remaining part of the capsule from the loading receptacle into the chamber so that the contents of the capsule may be inhaled through the nozzle. |
