  • Publication number: 20090272377
    Abstract: The present invention is directed generally to a nebulizer for the formation of micro-droplets from liquid medicaments for respiratory patient treatment, and more specifically, to a baffled nebulizer wherein the baffle oscillates within the nebulizer. The oscillating baffle operates such that as a constant stream of liquid medicament strikes a target region within the oscillating baffle, at a first position the medicament stream forms a predominant fraction of macro-droplets, which are substantially recycled, and in a second position, the medicament stream forms a predominant fraction of micro-droplet respirable aerosol. The oscillating baffle moves between the first and second positions based upon the respiration of the patient, thus moving the oscillating baffle into the second position only when inhalation occurs, thereby preventing excessive waste of liquid medicament, and improving patient therapy.
