Background
Generally speaking, "the disease enters from the mouth", however, respiratory diseases such as influenza, allergic rhinitis, tracheobronchitis and the like are mostly transmitted through the air, and people often easily ignore the way of entering the disease from the nose. The probability of pathogenic bacteria, allergens etc. entering the body from the nasal route is about 5.8 times higher than from the mouth. Under the conditions that the environmental pollution is increasingly serious and the haze and PM2.5 are gradually increased, the rhinitis and the upper respiratory tract infection frequently occur. The nasal cavity is obstructed in mucociliary transmission, and symptoms such as nasal obstruction and nasal discharge occur. At this time, many patients first respond to nose blowing or drug relief, but neglect a safe and convenient treatment of nasal irrigation. Nasal cavity cleaning is used as auxiliary treatment, nasal symptoms can be better improved, and the dosage of the medicine is reduced.
However, when the existing patient is flushed by water for lowering the head, the cleaning liquid cannot be recovered in time, so that the liquid easily flows into the paranasal sinuses along the nasal cavity, the nerve around the paranasal sinuses is stimulated to cause headache, dirty nasal discharge doped in the cleaning liquid easily causes inflammation of the paranasal sinuses, and other secondary diseases are generated, so that the patient cannot be compensated. In addition, the nasal cavity needs to be flushed by repeatedly filling liquid, so that the efficiency is low.
Another method for cleaning the nasal cavity is to clean the nasal cavity by dipping the cleaning solution with a cotton swab or forceps. The method is only suitable for the patients with light dirt in nasal cavity, and for the patients with hardened nasal secretion or nasal obstruction and running nose, the patients need to be cleaned repeatedly for many times. In addition, nasal mucosa of a patient with cold or rhinitis is usually congested, and the blood vessel wall is very fragile, so nasal tissues are easily damaged in the cleaning and wiping process, and epistaxis is caused.
