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.
Claims25
An inhalation device for administering a powdered medicament by inhalation comprising
- 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.
An inhalation device for administering a powdered medicament by inhalation comprising a suction tube through which the medicament is drawn on inhalation by a user, a blister pack and a housing which carries the blister pack, 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, wherein the inhalation device further comprises biasing means which move the suction tube into a position where it is biased away from the housing surfaces to facilitate grasping by the user when the inhalation device is ready for use,
- wherein the biasing means raise the suction tube away from the housing surfaces,
- wherein the housing is a carrier for the blister pack,
- wherein the distal end of the suction tube is removably hinged on the carrier,
- wherein the biasing means is an elongate resilient member, one end of which is connected to the suction tube and the other end of which is connected to the carrier,
- wherein the resilient member biases the suction tube on the hinge from a first position where the suction tube is able to lie adjacent to the carrier to a second position where the suction tube is raised away from the carrier.
An inhalation device for administering a powdered medicament by inhalation comprising a suction tube through which the medicament is drawn on inhalation by a user, a blister pack and a housing which carries the blister pack, 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, wherein the inhalation device further comprises biasing means which move the suction tube into a position where it is biased away from the housing surfaces to facilitate grasping by the user when the inhalation device is ready for use,
- wherein the biasing means raise the suction tube away from the housing surfaces,
- wherein the housing is a carrier for the blister pack,
- wherein the distal end of the suction tube is removably hinged on the carrier,
- wherein the biasing means is a sprung element which forms part of the hinge on the carrier,
- wherein the sprung element biases the suction tube on the hinge from a first position where the suction tube is able to lie adjacent to the carrier to a second position where the suction tube is raised away from the carrier.
An inhalation device for administering a powdered medicament by inhalation comprising a suction tube through which the medicament is drawn on inhalation by a user, a blister pack and a housing which carries the blister pack, 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, wherein the inhalation device further comprises biasing means which move the suction tube into a position where it is biased away from the housing surfaces to facilitate grasping by the user when the inhalation device is ready for use,
- wherein the housing comprises an outer case and a carrier which carries the blister pack,
- wherein the distal end of the suction tube is removably hinged on the outer case,
- wherein the biasing means is an elongate resilient member, one end of which is connected to the suction tube and the other end of which is connected to the carrier,
- wherein the resilient member moves the suction tube on the hinge from a first position where the suction tube is able to lie adjacent to the outer case to a second position where the suction tube projects away from the outer case,
- wherein the resilient member is in the form of a strip with one or more preformed waves which can unfold under tension.
