Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-4 As shown, this utility model provides a high-flow oxygen therapy nasal cannula for indwelling dual-tube examination, including a nasal cannula body 1, an oxygen tube 2 fixedly connected to one end of the tube body 1, a first catheter 3 fixedly connected to one side of the tube body 1, a second catheter 4 fixedly connected to one side of the tube body 1 and located on the same side as the first catheter 3, a channel tube 5 fixedly connected to the inner side of the second catheter 4, a plurality of circumferentially arranged side holes 6 opened at the end of the second catheter 4 and at the edge of the channel tube 5, a plurality of uniformly arranged limiting members fixedly connected to the inner side wall of the channel tube 5, and a sealing member fixedly connected to the other side of the tube body 1 for sealing the channel tube 5. The limiting members are used to prevent displacement of the gastric tube or bronchoscope, and the channel tube 5 has a funnel-shaped opening facing outward.

[0023] It should be added that the tube body 1, the first catheter 3, the second catheter 4, and the channel tube 5 are made of silicone as a single piece. The second catheter 4 and the channel tube 5 are overlapped, with a gap between them to allow oxygen supplied by the oxygen tube 2 to enter the tube body 1 and exit through the first catheter 3 and the second catheter 4. The gastric tube or bronchoscope can be inserted into the patient's nasal cavity through the channel tube 5 to effectively maintain high-flow oxygen therapy, improve the patient's oxygenation status, ensure enteral nutrition with the gastric tube, safely provide enteral nutrition support, provide energy and nutrition, safely and efficiently complete electronic bronchoscopy, reduce patient discomfort, improve patient compliance, simplify nursing procedures, improve nursing efficiency, and reduce the risks of infection and aspiration.

[0024] Among them, the channel tube 5 has a trumpet-shaped opening, which facilitates the insertion of a gastric tube or bronchoscope into the nasal cavity.

[0025] Specifically, the limiting component includes multiple elastic rings 7 that are uniformly arranged and fixedly connected to the inner wall of the channel tube 5. The elastic rings 7 are hollow inside, and a support ring 10 is fixedly connected to the inner side of the elastic rings 7. The cross-section of the elastic rings 7 is arc-shaped.

[0026] Both the elastic ring 7 and the support ring 10 are made of silicone. The elastic ring 7 can wrap around the outside of the gastric tube or bronchoscope. The elastic ring 7 can expand or contract. The support ring 10 can support the elastic ring 7. Multiple elastic rings 7 can tightly wrap around the outside of gastric tubes or bronchoscopes of different diameters, reducing gas leakage and providing good fixation. At the same time, it can also prevent the gastric tube or bronchoscope from shifting.

[0027] More specifically, the sealing element includes a connecting strip 8 fixedly connected to the other side of the tube body 1, a sealing cap 9 fixedly connected to one end of the connecting strip 8, the sealing cap 9 being frustoconical, two limiting rings 11 fixedly connected to the outer side of the sealing cap 9, and a groove 12 provided for the limiting rings 11 to be inserted into the inner wall of the channel tube 5.

[0028] Furthermore, both the connecting strap 8 and the sealing cap 9 are made of rubber. The sealing cap 9 has a connecting handle at its end. The connecting strap 8 is fixedly connected to the sealing cap 9 through the connecting handle. The connecting handle allows the sealing cap 9 to be easily pulled or pushed in and out of the channel tube 5. The two limiting rings 11 on the edge of the sealing cap 9 are inserted into the groove 12 to lock and fix the sealing cap 9. At the same time, the sealing cap 9 and the channel tube 5 are fixed by interference fit to prevent outside air from carrying impurities or dust into the patient's nasal cavity when the channel tube 5 is not in use, thus avoiding discomfort or infection to the patient.

[0029] Working principle: First, the first catheter 3 and the second catheter 4 on one side of the tube body 1 are inserted into the patient's two nostrils respectively. Then, oxygen is supplied to the first catheter 3 and the second catheter 4 on one side of the tube body 1 through the oxygen supply tube. The oxygen is discharged through the side hole 6 at one end of the first catheter 3 and the second catheter 4, allowing the patient to receive high-flow oxygen therapy. When it is necessary to insert a gastric tube or perform a bronchoscopy, the connecting handle is used to drive the sealing cap 9 out of the channel tube 5. The gastric tube or bronchoscope is then inserted into the nasal cavity through the channel tube 5. At this time, the support ring 10 supports the elastic ring 7. At the same time, multiple elastic rings 7 tightly wrap around the outside of the gastric tube or bronchoscope to reduce gas leakage and prevent external gas from entering the patient's nasal cavity and causing discomfort. Thus, one channel is dedicated to delivering high-flow oxygen, while the other channel is used to ensure the delivery of oxygen while inserting a gastric tube or performing an electronic bronchoscopy.
