An inhaler for delivery of a medicament by inhalation is disclosed. The inhaler comprises a dispensing mechanism, the dispensing mechanism being configured to dispense a dose of medicament on actuation. The inhaler further comprises a dose counting mechanism comprising a counter and a translating member. The translating member comprises a pawl. The counter comprises a first count wheel, a second count wheel and an intermediate wheel engaged with the second count wheel and in selective engagement with the first count wheel. When the inhaler is fired to dispense a dose of medicament, the dispensing mechanism moves the translating member in a substantially linear direction. The pawl thus rotates the first count wheel, and as the first count wheel rotates, the intermediate wheel is selectively engaged thereby selectively rotating the second count wheel to count the doses of the inhaler.

Inhaler counter

In an exemplary embodiment, a breath actuated inhaler (BAI) actuator may include a loading element capable of being loaded with an actuation force and a breath actuated trigger mechanism arranged to counteract the actuation force of the loading element and to fire the actuator by releasing the actuation force of the loading element in response to an inhalation breath. An actuation locking device may be moveable between a locked position wherein it relieves the actuation force from the trigger mechanism setting the trigger mechanism in a neutral position, and an armed position wherein the trigger mechanism is set in an armed position.

A breath-actuated inhaler for delivery of a medicament by inhalation from a canister () which is compressible to deliver a dose of medicament. The inhaler comprises a housing () for holding a canister () and including a mouthpiece () for delivery of a dose of medicament from a canister () held in the housing; and an actuation mechanism () for compressing a canister () held in the housing () in response to inhalation at the mouthpiece (). The housing includes two separable portions (). The first housing portion () mounts the actuation mechanism (). The second housing portion () houses the mouthpiece () and a duct () shaped to direct an inhalation flow from the mouthpeice () to the first housing portion () for triggering the actuation mechanism (). The duct () and the mouthpiece () are integrally formed and separable from the second housing portion ().
