ABSTRACT:
A hand-held inhalation responsive nebuliser by which a nebulised air stream is created for quick and efficient delivery of a fluid medication to the respiratory tract of a patient through the deep lung. The nebuliser includes a normally open electrical switch and a rotatable trigger ring extending laterally across an air flow path through which a supply of non-medicated ambient air is drawn during inhalation by the patient. The ambient air supply drawn through the nebuliser causes the trigger ring to rotate into contact with and close the electrical switch, whereby a piezoelectric disk is energized to vibrate an emitter mesh. A metered volume of fluid medication delivered to the emitter mesh from a pre-filled medication cartridge is accelerated and pulled through the mesh as a fine mist of fluid droplets to form a nebulised medication plume. The nebulised medication plume is mixed in the mouthpiece of the nebuliser with the supply of non-medicated ambient air to create the nebulised air stream.
