Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a nasal medication device for respiratory tract infection in children. Background Art

[0002] Respiratory tract infection, also known as upper respiratory tract infection, is a common disease in children. It is a general term for acute inflammation between the nasal cavity and the throat. Due to the imperfect morphological development and physiological function of the nose in children, local nasopharyngeal inflammatory symptoms, also known as catarrhal symptoms, are more likely to occur during upper respiratory tract infection, manifested as congestion, flushing, swelling of the nasal mucosa, frequent sneezing, followed by nasal discharge from one or both nostrils. Inflammatory irritation of the nasal cavity in children can easily cause acute adenoids in children, and long-term inflammatory stimulation can lead to adenoid hypertrophy; the spread of inflammation and improper nose blowing can lead to purulent sinusitis and ear middle ear inflammation; and nasal inflammation caused by nasal mucus backflowing into the pharynx can cause pharyngitis and bronchitis. Therefore, the treatment of local nasal problems in children with upper respiratory tract infection is more important than that in adults.

[0003] Currently, when pediatricians administer nasal medications to children, they need to use a spray head to spray the medication into the nasal cavity. However, since children have more nasal secretions when they have respiratory infections, the nasal cavity is often blocked. Therefore, the nasal secretions need to be cleaned before spraying. Generally, medical staff will use a nasal rinser to flush the inner wall of the nasal cavity with water impact. However, since children are active and the cleaning time is long, the cleaning operation is often difficult to perform and the cleaning efficiency is poor, which ultimately leads to poor spray treatment effects and prolongs the recovery time of children.
