[0041] By sliding the output connection pipe 7, the distance between the two nasal plug pipes 9 is adjusted to realize the use for different patients, and then the slidably arranged output connection pipe 7 is fixed by the fixing component, thereby fixing the distance between the two nasal plug pipes 9. When anesthesia is introduced into the air delivery pipe 6 through the external connection sleeve 4, the anesthesia will be injected into the patient's nasal cavity through the nasal plug pipe 9.

[0042] Embodiment 2:

[0043] As Figure 2 shown, the anesthesia nasal mask disclosed in Embodiment 2 of the present utility model has basically the same structure as that in Embodiment 1, and the differences are as follows:

[0044] The cross-section of the flexible bracket 1 is in a "C" shape, and a matching nasal wing card slot 2 is opened on one side of the central wall of the flexible bracket 1;

[0045] Binding through holes 3 are opened at the central positions of both side walls of the flexible bracket 1;

[0046] The air delivery pipe 6 is fixedly arranged at the ends of both side walls of the flexible bracket 1, and one end of the air delivery pipe 6 is fixedly connected with a matching external connection sleeve 4, and the external connection sleeve 4 is communicated with the air delivery pipe 6;

[0047] An end-tidal carbon dioxide detection hole 5 is fixedly arranged on the outer surface of the external connection sleeve 4;

[0048] Limiting sliding grooves 8 are opened on the surface of the air delivery pipe 6, there are two groups of the limiting sliding grooves 8, the two groups of limiting sliding grooves 8 are evenly and symmetrically distributed, and each group of limiting sliding grooves 8 includes two evenly spaced ones;

[0049] The cross section of the output connecting pipe 7 is a hollow annular structure, and the output connecting pipe 7 is sealingly slidably arranged between the two limiting chutes 8. The outer surface of the gas delivery pipe 6 is provided with a plurality of groups of spaced vent holes 10 at positions corresponding to the output connecting pipe 7, and the vent holes 10 are located between the two limiting chutes 8.

[0050] By cooperating with the output connecting tube 7 and the limiting slide 8, the distance between the two sets of nasal congestion tubes 9 can be adjusted so that it can be suitable for different patients. The output connecting tube 7 can be rotated along the limiting slide 8. By rotating the limiting slide 8, the angle between the flexible bracket 1 and the nasal congestion tube 9 can be adjusted to make it more suitable for the patient wearing it.

[0051] Example 3:

[0052] like Figure 3-Figure 4 As shown, the structure of the anesthesia nasal mask disclosed in the third embodiment of the present invention is basically the same as that in the second embodiment, except that:

[0053] The fixing assembly includes a clearance groove 16 formed on the inner portion of the outer wall of the gas delivery pipe 6, and the clearance groove 16 matches the sliding position of the output connecting pipe 7;

[0054] A matching top plate 18 is slidably provided inside the give way groove 16, and a second return spring 17 is provided between the bottom of the top plate 18 and the bottom end of the inner portion of the give way groove 16. The second return spring 17 is provided in multiple groups, and the multiple groups of the second return spring 17 are evenly spaced.

[0055] The top of the inner portion of the said clearance groove 16 is provided with a through groove 19, and the said through groove 19 is provided in multiple groups, and the said multiple groups of through grooves 19 are evenly spaced.

[0056] A matching insertion rod 20 is inserted into each of the through slots 19. Each of the insertion rods 20 is elastically inserted into the through slot 19 through the cooperation of the second return spring 17 and the top plate 18. A matching fixing groove 21 is formed on the side wall of the output connecting pipe 7 at the position corresponding to one group of the insertion rods 20.

[0057] A limiting groove 11 is formed on the outer surface of the gas delivery pipe 6. A matching pull rod 13 is slidably provided inside the limiting groove 11. A first return spring 12 is provided between a side wall of the pull rod 13 and the inner wall of the limiting groove 11. The pull rod 13 elastically slides inside the limiting groove 11 via the first return spring 12.

[0058] A first air storage bag 14 is provided between a side wall of the pull rod 13 away from the first return spring 12 and an inner side wall of the limiting groove 11. An exhaust pipe 15 is provided between the interior of the first air storage bag 14 and the interior of the giving way groove 16. The first air storage bag 14 is connected to the giving way groove 16 through the exhaust pipe 15. The elastic force of the first return spring 12 is greater than the total elastic force of the second return springs 17.

[0059] Through the cooperation of the first return spring 12, the pull rod 13 squeezes the first air storage bag 14, so that the gas inside the first air storage bag 14 is discharged to the inside of the makeshift groove 16 through the exhaust pipe 15. The elastically arranged top plate 18 drives the insertion rod 20 to move upward under the support of the gas. When the insertion rod 20 is inserted into the inside of the fixing groove 21, the output connecting tube 7 can be limited and fixed, thereby fixing the position of the nasal congestion tube 9.

[0060] This solution is specifically as follows: the pull rod 13 is pulled outward so that the pull rod 13 no longer squeezes the first air storage bag 14. At this time, under the action of the second return spring 17, the top plate 18 drives the insertion rod 20 to withdraw from the inside of the fixing groove 21, and then the positions of the two sets of output connecting tubes 7 are adjusted so that the nasal congestion tube 9 connected to the output connecting tube 7 can adapt to the patient's nostrils. Then, the force on the pull rod 13 is canceled, and the first return spring 12 cooperates to realize the squeezing of the first air storage bag 14 by the pull rod 13, so that the gas inside the first air storage bag 14 is discharged to the inside of the give way groove 16 through the exhaust pipe 15. The elastically arranged top plate 18 drives the insertion rod 20 to move upward under the support of the gas. When the insertion rod 20 is inserted into the inside of the fixing groove 21, the output connecting tube 7 can be limited and fixed, thereby fixing the position of the nasal congestion tube 9.

[0061] The flexible bracket 1 is fixed to the patient's face by cooperating with the strap and the strap through hole 3. At the same time, the nasal tube 9 is inserted into the patient's nostrils, and then anesthesia is introduced into the air supply tube 6 through the external connecting sleeve 4. When anesthesia is introduced, the anesthesia will be injected into the patient's nasal cavity through the nasal tube 9.
