Abstract

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 centre 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.
