One end of the oxygen supply extension tube is provided with a tapered tube, and the other end of the oxygen supply extension tube is sleeved with a bottom box. A filter layer is installed on the bottom box, and a buckle cover is sleeved on the bottom box. A connecting tube is inserted on the buckle cover. One end of the connecting tube is installed with an oxygen supply inlet tube, a branch tube is installed on the side wall surface of the oxygen supply inlet tube, and a rubber cap is sleeved on one end of the branch tube;

[0007] The filter layer includes filter paper installed on the bottom box, a filter net is installed on the filter paper, and the buckle cover is movably attached to the filter net.

[0008] Preferably, a notch is opened on the ventilator connector limit baffle, and the oxygen supply extension tube is installed on the notch.

[0010] Preferably, a steel wire ring is installed on the inner side wall surface of the main airway.

[0011] Preferably, the oxygen supply extension tube and the tapered tube are of an integral structure.

[0012] Preferably, one end of the main airway is provided with an inclined surface, and one end of the tapered tube is flush with one end of the main airway.

[0013] Advantageous Effects

[0014] The present invention provides a jet oxygen supply humidifying nasopharyngeal airway. Compared with the prior art, it has the following

[0015] Advantages:

[0016] Oxygen enters from the oxygen supply inlet tube, and the liquid medicine or physiological saline is injected by a syringe or an infusion needle and flows into the branch tube through the rubber cap, and then enters the oxygen supply inlet tube, playing a role in humidifying the oxygen and improving the comfort of the patient during use; at the same time, it is convenient to administer medicine to asthma patients. The oxygen and the liquid medicine or physiological saline enter the oxygen supply extension tube after being filtered by the filter screen and the filter paper at the same time, avoiding impurities in the oxygen and the liquid medicine or physiological saline and ensuring the cleanliness of the oxygen and the liquid medicine or physiological saline; the oxygen and the liquid medicine or physiological saline are then input from one end of the conical tube to the nasopharyngeal part of the patient. The oxygen supply extension tube and the conical tube cooperate to make the channel for delivering oxygen show a gradually narrowing trend, increasing the pressure and expanding the jet distance of the oxygen, thus improving the oxygen supply quality.

[0021] Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment: Please refer to Figures 1 - 3, one end of the main ventilation duct 1 is connected to a ventilator. The ventilator connection joint limit baffle 2 is used to limit the connection position of the main ventilation duct 1 and the ventilator. The other end of the main ventilation duct 1 is inserted into the patient's nostril. The rubber cap 12 is used to insert a syringe or infusion needle. The rubber cap 12 makes the insertion part of the syringe or infusion needle have good sealing performance and will not leak air. When in use, oxygen enters from the oxygen supply inlet pipe 10. The syringe or infusion needle is inserted on the rubber cap 12. The liquid medicine or physiological saline flows into the branch pipe 11 through the syringe or infusion needle and then enters the oxygen supply inlet pipe 10, playing a role in humidifying the oxygen and improving the comfort of the patient during use; at the same time, it is also convenient to administer medicine to asthma patients. The oxygen and the liquid medicine or physiological saline enter the oxygen supply extension pipe 3 after being filtered by the filter net 7 and the filter paper 6 at the same time.

One end of the conical tube 4 is located at the lowest point of the inclined surface on the main ventilation duct 1, forming a cyclone with the gas generated by the patient's breathing and expanding the contact area between the oxygen and the patient's nasopharyngeal part;

[0024] Preferably, furthermore, a notch 13 is opened on the ventilator connection joint limit baffle 2. The oxygen supply extension pipe 3 is installed on the notch 13 for clamping the oxygen supply extension pipe 3 and supporting the oxygen supply extension pipe 3;
