An actuator for an inhaler for administering medicament by inhalation, comprising: a main body ( ) comprising an elongate tubular member ( ) for receiving a canister ( ) containing medicament and having a valve stem ( ) extending therefrom, the tubular member ( ) including a lateral opening ( ) at one end thereof; and an outlet assembly ( ) comprising a mouthpiece for guiding medicament to the mouth of a user and a nozzle block ( ) for receiving the valve stem ( ) of the canister ( ) and delivering medicament from the canister ( ) into the mouthpiece, the outlet assembly ( ) being detachably mounted, through the lateral opening ( ), to the main body ( ) at an angle transverse to the length of the tubular member ( ); characterized in that one of the main body ( ) and the outlet assembly ( ) further comprises at least one resiliently biased member, which is configured to engage with at least one part of the other of the main body ( ) and the outlet assembly ( ) and thereby hold the outlet assembly ( ) to the main body ( ), and at least one release component which in use is acted upon to enable release of the outlet assembly ( ) from the main body ( ).

Inhalation device

A breath actuated inhaler for delivering medicament by inhalation, comprising a housing having a mouthpiece and defining an air flow path extending from the mouthpiece through the housing; the housing holding a replaceable canister of medicament actuatable to deliver a dose of medicament into the air flow path, wherein the housing defines an opening in the air flow path and the opening is closed by a closure element connected to and replaceable with the canister. The closure element acts as a safety feature because it is only closed when the inhaler is used with a canister to which a closure element is connected the closure element carries an indication of the type of medicament in the canister to allow the user to recognise the type of medicament. A plurality of inhalers may be provided in which each given inhaler has an opening with a different shape and has a closure element with a shape which conforms with the opening of the given inhaler but which does not conform with the openings of the other inhalers.

Inhaler

Inhaler refill

The actuation mechanism of a breath-actuated inhaler for delivery of a medicament by inhalation. The actuation mechanism includes a pre-loading mechanism is arranged to load the resilient loading element by manual depression of two contact members movable relative to the housing and disposed opposite one another on either side of the axis of a canister held in the housing. The actuation mechanism also includes a pivotably mounted trigger vane arranged to be moved by inhalation at the mouthpiece to cause operation of the actuation mechanism, wherein the trigger vane is mounted to pivot about an axis passing through the center of mass of the trigger. The triggering mechanism comprises a knee joint having a locked position where the knee joint holds the resilient loading element against compression of the canister and a trigger responsive to the inhalation at the mouthpiece to break the knee joint into a broken position where the knee joint releases the resilient loading element to allow compression of the canister. Furthermore the trigger comprises a second knee joint connected to the first-mentioned knee joint and having a locked position where the second knee joint holds the first knee joint in its locked position and movable in response to inhalation at the mouthpiece to a broken position to break the first knee joint.
