[0002] Respiratory tract infections not only affect the healthy development of children, but may also cause a variety of complications, which can even be life-threatening in severe cases. Therefore, the treatment of respiratory diseases, especially the method of drug administration, has become a research focus in the medical field.

[0003] At present, the method of atomizing drugs into aerosols and inhaling them through the respiratory system for administration has gradually attracted the attention of the medical community and patients. Major pharmaceutical companies have launched special agents and adjusted their formulas to make them more suitable for aerosol inhalation. With the long-term efforts of all parties, aerosol administration has become a common method of administration. However, traditional nebulizers have not made significant technological progress and still remain in the saturated atomization method. In this way, after the drug is added, the nebulizer will continue to form an aerosol. Since breathing is intermittent, a large amount of drug will be wasted during exhalation, resulting in low drug utilization.

[0004] In the treatment process of respiratory medicine, drug delivery devices play a vital role. Traditional drug delivery devices have many shortcomings. Although some devices have achieved atomization of drugs, the atomization effect is not ideal, the drug particle size is uneven, which affects the patient's absorption effect and cannot ensure the uniform mixing of drugs.
