Patent ID: 7389775

Claim:
An inhalation device comprising a medicament pack which is configured as a strip having a length, said medicament pack comprising a plurality of containers which: are arranged along the length of the strip, and each contain an inhalable medicament powder; wherein the device further comprises: an outlet at which a user is able to inhale on the device; and an actuating mechanism which is adapted upon each user actuation of the device to act on the pack to open one of the containers and to move the pack into a position where said opened container is in flow communication with the outlet so that the medicament powder in the opened container is able to be entrained into the user's respiratory tract by user inhalation at the outlet; and wherein the actuating mechanism has: a resettable actuation member mounted for movement by a user from a first postion to a second postion to actuate the device and resettable to the first postion ready for movement back to the second postion for another actuation of the device; an opening mechanism associated with the resettable actuation member such that each user movement of the resettable actuation member from the first postion to the second postion is transmitted to the opening mechanism to cause the opening mechanism to open said one container; and an indexing mechanism associated with the resettable actuation member such that each user movement of the resettable actuation member from the first position to the second position is transmitted to the indexing mechanism to cause the indexing mechanism to index the opened container into flow communication with the outlet; and wherein the actuating mechanism is further adapted such that each resetting movement of the actuation member from the second postion to the first position is not transmitted to the opening and indexing mechanisms so that the pack remains stationary during said resetting movement.
