Nasal aspirator is a tool specially used to clean the nasal cavity and suck the nose for babies. There are mainly four types of nasal aspirators: pump nasal aspirator, mouth suction nasal aspirator, spray nasal aspirator, and vapor nasal aspirator. The nasal aspirator has a specially designed suction nozzle to solve the problem of excessive penetration of the nostril and damage to the nasal mucosa during use. The suction force is gentle, slow and slow, directly controlled by an adult, which can continuously and quickly remove the secretions in the nasal cavity, clean, completely sucked, and no nasal mucus remains. Generally, babies can use a nasal aspirator when they are about 2 months old, but parents must pay attention to choosing high-quality products.
