Nebulizer

A nebulizer is a device that can be used for converting a liquid into droplets. Medical nebulizers that nebulize a fluid into an aerosol for inhalation by a patient are well-known devices commonly used for the treatment of certain conditions and diseases. Nebulizers have applications for conscious, spontaneously-breathing patients and for controlled, ventilated patients. Persons requiring treatment of certain kinds of respiratory conditions frequently need to have medications delivered directly to the lungs. Nebulized or aerosolized solutions are the preferred method of delivery of respiratory medication because the medicant is fragmented into small particles that are more efficiently deposited near sites of drug activity in the lungs. Inhalation nebulizers deliver therapeutically effective amounts of pharmaceuticals by forming an aerosol which includes particles of a size that can easily be inhaled. The aerosol can be used, for example, by a patient within the bounds of an inhalation therapy, whereby the therapeutically effective pharmaceutical or drug reaches the patient's respiratory tract upon inhalation. Such inhalation treatment is highly effective for conditions effecting the subject's respiratory organs. Further, since the lungs are close to the heart and the blood circulatory system of the body, drug administration by inhalation provides an effective and rapid delivery system to all organs of the body. Various types of nebulizers have been designed for generating a liquid medication aerosol for delivery to a patient's lungs. In nebulizers, a diverter is primarily used to direct a gas across a liquid channel to create a venturi effect causing the liquid to be entrained into the gas stream. As a result of the nebulization process described above, the fluid is transformed into an aerosol, that is, the fluid is caused to form small particles that are suspended in the air and that have a particle size in a range suitable for the intended therapy. A common therapy is inhalation therapy, whereby a patient inhales a medicated aerosol to treat an ailment, such as asthma. A nebulizer assembly particularly applied in aerosol nebulizers comprises an oscillator driver for loading an aerosol excitation device provided on an acting plane, and a liquid delivery device adjacently disposed to the aerosol excitation device for supplying an impingement baffle of the excitation device with liquid membranes for further micro loading and impingement. Therefore the energy of the excitation device is totally acted onto the liquid bodies in micro units and maximizes the efficiency thereof.
