Medical nebulizers are primarily used to treat various upper and lower respiratory system diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis, and other diseases occurring in the trachea, bronchi, alveoli, and pleural cavity. Nebulized inhalation therapy is an important and effective treatment method for respiratory diseases. A nebulizer atomizes medication into tiny particles, which are then inhaled and deposited in the respiratory tract and lungs, achieving a painless, rapid, and effective treatment.
