1. The oval-shaped soft silicone nose is close to the nostril to avoid excessive penetration of the nostril and damage to the nasal mucosa. 2. The suction force is gentle and slow, which is directly controlled by the adult, so there is no need to worry about sucking the nose. 3. It can continuously and quickly remove the secretions in the nasal cavity, completely absorb it cleanly, and leave no nasal mucus. 4. The bottle is transparent, which can confirm the state and amount of the child’s nose. 5. The snot sucked out is in the bottle, so the snot will not flow back into the child’s nasal cavity or directly flow into the mouth.
