Abstract

An inhalation device for administering a powdered medicament by inhalation including a suction tube through which the medicament is drawn on inhalation by a user, a blister pack, a housing which carries the blister pack and has housing surfaces, the suction tube being removably connected to the housing and having a distal end which can interact with the blister pack and a proximal end through which the user inhales, and a resilient member that resiliently biases the suction tube into a position where it is spaced from the housing surfaces to facilitate grasping of the suction tube by the user when the inhalation device is ready for use.
