20080202506 | WATERFALL NEBULIZER - The present invention relates generally to a nebulizer, and more particularly but not exclusively to a compact nebulizer that efficiently utilizes medication. | 08-28-2008 |
20090050140 | PORE STRUCTURES FOR REDUCED PRESSURE AEROSOLIZATION - A nozzle comprising a thin, flexible substantially planar polymeric film having a plurality of pores with structures allowing for generation of an aerosol at reduced extrusion pressure is disclosed. The pores can comprise at least two sections, or steps, in which the thickness of the membrane is reduced in stepwise fashion, or the pores can be tapered. Nozzles formed comprising pores having such structures permit aerosol generation at lower extrusion pressures, thereby allowing for decreased weight of aerosolization devices, increased efficiency, increased portability and increased battery life. The pore structures also allow for the use of thicker, more easily processed polymeric films in manufacturing while having a thinner, more efficient aerosolization area. The use of decreased extrusion pressures also results in increased uniformity in aerosol generation and improved reliability of other components. | 02-26-2009 |

20090272377 | Inhalation-controlled nebulizer with oscillating baffle - 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. | 11-05-2009 |
