[0002] Patients with nasal-sinus related diseases include children, adolescents and other age groups. Clinical treatments for nasal-sinus diseases include local nasal administration, systemic administration, surgical treatment and other treatment methods. Local nasal administration is the first-line treatment method in the diagnosis and treatment guidelines, and it is safe and effective, especially for special populations such as children and pregnant women. At present, the main method of local nasal administration in clinical practice is that the drug container is sprayed into the nasal cavity in the form of water mist through the nozzle under the action of external force, and the patient uses and controls it by himself, such as the drug containers used for mometasone furoate nasal spray and oxymetazoline nasal spray.

[0003] The current nasal drug delivery devices are inconvenient to operate and control, especially for children. They often require cooperation between the adult drug administerer and the child. If the cooperation is not good, the child will feel uncomfortable and refuse to accept treatment. Secondly, the spray heads of the current nasal drug delivery devices are rough, thick and short. When used, it is not easy to fully diffuse the drug to the middle and back parts of the nasal cavity, resulting in poor treatment effect. Furthermore, when used, the drug spray head moves relatively in the nasal cavity, which can easily damage the nasal mucosa, cause nose bleeding and nasal discomfort.
