The commonly used nasopharyngeal tube is an elastic tube with a trumpet-shaped end and an angled end. It is first inserted into the pharyngeal cavity through the nostril. The nasopharyngeal tube is mainly used for patients who are awake after general anesthesia or comatose patients, as well as patients who have undergone oral surgery.

[0003] However, the existing nasopharyngeal tube channel has the following shortcomings: since the nasopharyngeal tube channel can only provide ventilation function, it cannot effectively remove secretions or blood in the nasopharynx. These substances will be retained in the nasopharynx, causing the risk of infection, or be accidentally inhaled into the lower respiratory tract, causing lung complications.

[0004] Therefore, it is necessary to provide an improved nasopharyngeal tube channel that can provide ventilation and absorption functions at the same time, avoid nasopharyngeal secretions or blood from blocking the ventilation holes, clear the nasopharyngeal secretions or blood, and reduce the risk of infection and aspiration.
