[0002] Currently, throat ventilation tubes generally achieve ventilation, supplemented by automatic sputum suction.

[0003] The patent "An Adjustable Throat Ventilation Tube" with publication number CN 116785545 A discloses an adjustable throat ventilating tube, including a deformable ventilating tube, an anti-clogging pneumatic ball, a negative pressure guide tube, an airbag ball and a pressing drive mechanism. The deformable ventilating tube includes a ventilating elbow and a deformable connector installed at the outer end of the ventilating elbow. The end of the ventilating elbow is machined to have an installation opening. The anti-clogging pneumatic ball is arranged in the installation opening. A guide cavity is opened at the bottom of the installation opening. The end of the guide cavity is connected to the container. The receiving sleeve is connected with the receiving sleeve, the receiving sleeve is installed on the ventilation elbow, one end of the negative pressure guide tube is connected with the receiving sleeve and the outer end is connected with the airbag ball, a drainage tube is connected below the airbag ball, the airbag ball is embedded in the outer end of the ventilation elbow, the pressing drive mechanism is installed below the airbag ball and is used in conjunction with the airbag ball; the negative pressure guide tube is negatively sucked by the pressing drive mechanism, so that the sputum in the patient's throat can be automatically extracted to achieve the purpose of preventing obstruction.

[0004] The disadvantage is that since the negative pressure guide tube uses a soft tube, when congestion occurs in the negative pressure guide tube, negative pressure suction will cause the negative pressure guide tube to deform, resulting in suction difficulties; and sputum is retained in the negative pressure guide tube, which can easily cause infection to the patient.
