Abstract (en)
[origin: GB2553535A] A breath-responsive metered dose inhaler having a trigger mechanism including a breath responsive member such as a vane 110 moveable upon inhalation of the user from a primed position in which the inhaler is prevented from delivering medicament, to a triggered position in which the medicament is delivered to the user. The vane 110 is coupled to a spring 115 which may be a helical spring, wherein the spring 115 is configured to bias the vane 110 from its triggered position to its primed position by flexure along its longitudinal axis. The vane 110 may connect to a toggle mechanism 120 via the spring 115.
