Abstract
The present disclosure provides an inhaler having a vibration element for aerosolizing medicament contained in a blister pack, wherein individual blister packs are positioned within the housing to be simultaneously engaged with the flow channel and the vibration element. The flow channel includes a blister pack clamping surface that engages the blister pack near the top of the crown and allows the blister three rotational degrees of freedom. The advantages of this arrangement include improved consistency and higher airspeed of the synthetic jet, as well as other advantages.
