USPTO Abstract

An inhaler for holding a canister ( 2 ) of medicament. The canister ( 2 ) has a mount ( 26 ) secured thereto mounting an indication member ( 41 ) movable slidably from a first state to a second state. A ratchet arrangement ( 41 a , 42 ) is provided between the mount ( 26 ) and the indication member ( 41 ) to make the movement irreversible. The inhaler has a catch ( 49 ) for moving the indication member from the first state to the second state on removal of the canister ( 2 ) from the inhaler. An electrical switch contact ( 48 ) detects the state of the indication member ( 41 ), thereby providing an indication of whether the canister ( 2 ) has been used before. An LCD display is controlled in response to the detection.
