[0003] In the prior art, the main function of the nasal oxygen tube is to assist the patient in breathing, and it is a medical device that actively injects oxygen into the supraglottic region of the patient through the nasal oxygen tube. However, during the use of the existing nasal oxygen tube, when oxygen is supplied to the patient through the nasal oxygen tube, the supply pressure of oxygen cannot be viewed. This leads to inconvenience in adjusting the oxygen supply pressure when the nasal oxygen tube is used by some inexperienced personnel such as novice medical staff. Therefore, we propose a nasal oxygen tube. Content of the Utility Model

And a cylindrical ventilation catheter 3 that is communicated with the catheter body 1 is installed on the periphery of the catheter body 1 near the right side of the back. Furthermore, a pressure measuring catheter 4 that is communicated with the catheter body 1 is installed corresponding to the ventilation catheter 3 on the periphery of the catheter body 1 near the left side of the back. Then, a pressure sensor 5 with a circular periphery is installed inside the pressure measuring catheter 4 near the back, which can effectively observe the inside of the patient's nasal cavity, so as to facilitate the insertion of the ventilation catheter 3 and the pressure measuring catheter 4 into the supraglottic region.

[0029] Embodiment 2

[0030] As Figures 1-3 shown, a square convex block 11 is installed on the front of the catheter body 1, and an anti-slip pad 12 is bonded to the front of the convex block 11. The convex block 11 is integrally formed with the catheter body 1, and the anti-slip pad 12 is made of medical-grade silicone material, which is convenient for medical staff to use the catheter body 1.

[0031] A first flexible pad 31 with a cross-sectional dimension consistent with that of the ventilation catheter 3 is installed on the back of the ventilation catheter 3, and a second flexible pad 41 with a cross-sectional dimension consistent with that of the pressure measuring catheter 4 is also installed on the back of the pressure measuring catheter 4. Both the first flexible pad 31 and the second flexible pad 41 are made of medical-grade silicone material, and both the ventilation catheter 3 and the pressure measuring catheter 4 are made of medical-grade rubber material, which can avoid hurting the patient's nasal cavity.

[0032] A plurality of circular air outlet holes 32 are provided near the top of the periphery of the ventilation catheter 3, and circular sealing caps 33 are clamped inside the air outlet holes 32, which can prevent the blockage of a single catheter.

[0033] An air inlet pipe 13 in the shape of a cylinder is connected to the center of the right side surface of the catheter main body 1, and a telescopic air pipe 14 is connected to the right side surface of the air inlet pipe 13. The telescopic air pipe 14 is convenient for adjusting the length. A cannula 15 in the shape of a cylinder is connected to the right side surface of the telescopic air pipe 14, and a dust-proof cover 16 is installed inside the cannula 15 extending to the right side. The dust-proof cover 16 is clamped with the cannula 15, which is convenient for connecting with the oxygen supply device.

[0034] The outer walls of the ventilation catheter 3 and the pressure measuring catheter 4 are both coated with a hydrophilic coating. When encountering water, the surface will become smooth, so as to move better in human tissues.

The pressure sensor 5 can be conveniently fixed through the inflation airbag 51, and at the same time, the air outlet end of the pressure measuring catheter 4 can also be sealed, so that oxygen directly impacts the pressure sensor 5, thus facilitating pressure measurement.

[0038] A second inflation pipe 54 and a data extension line 55 are installed inside the disassembly pipe 18 extending to both sides. The second inflation pipe 54 is inserted into the first inflation pipe 52, and the data extension line 55 is inserted into the data line 53.

After the connection is completed, connect the disassembly tube 18 to the wiring tube 17. Subsequently, connect the second inflatable tube 54 to an external air pump. After the connection, inflate the inflatable airbag 51 through the second inflatable tube 54 and the first inflatable tube 52 to fix the pressure sensor 5. Then, connect the data extension line 55 to a computer device, and connect the disassembly tube 18 and the intubation tube 15 to oxygen. At this time, the medical staff holds the bump 11, aligns the pressure measurement catheter 4 and the ventilation catheter 3 with the patient's nasal cavity, and inserts the pressure measurement catheter 4 and the ventilation catheter 3 above the glottis of the patient. Subsequently, the medical staff adjusts the oxygen supply pressure according to the value transmitted back by the pressure sensor 5 displayed on the computer. After completion, fix the elastic fixing band 61 on the patient's head, then adjust the length of the telescopic trachea 14, and remove the dust cover 16. Finally, disassemble the disassembly tube 18, and separate the second inflatable tube 54 and the first inflatable tube 52, and separate the data extension line 55 and the data line 53. Through the design of the utility model, it can effectively enable novice medical staff to conveniently adjust the oxygen pressure value to ensure the comfort of the patient.
