[0026] The support structure 2 is provided with two groups of support structures 2, and the two groups of support structures 2 are opposite to each other. The support structure 2 includes a fixed box 21, and the fixed box 21 is fixedly connected to the inside of one side surface of the breathing mask 1. The support structure 2 also includes a threaded rod 22, and the threaded rod 22 is threadedly connected to the inside of one side surface of the fixed box 21, and one end bearing of the threaded rod 22 is connected to a telescopic block 23, one side surface of the telescopic block 23 is fixedly connected to a silicone tooth sleeve 24, and the inner surface of the silicone tooth sleeve 24 is fixedly connected to a silicone cushion 25. The telescopic block 23 is inserted into the interior of the fixed box 21, and a limiting plate is provided on the outer surface of the other side of the telescopic block 23, and the outer size of the limiting plate is the same as the inner size of the fixed box 21. The silicone tooth sleeve 24 and the silicone cushion 25 are set to an arc shape. Figure 2 and Figure 5 As shown, when the device is in use, the threaded rod 22 is rotated to drive the telescopic block 23 to move inside the fixed box 21, and the movable range of the telescopic block 23 is limited by the limit plate, which makes the telescopic block 23 more stable when moving. The silicone tooth sleeve 24 and the silicone cushion 25 are made of silicone material. The elasticity and softness of the silicone material can avoid discomfort to the patient.

[0027] The positioning structure 3 includes a mounting plate 31, and the mounting plate 31 is fixedly connected to the outer surface of one side of the breathing mask 1, and the mounting plate 31 is located in the middle position of the two sets of fixing boxes 21. The positioning structure 3 also includes a mounting frame 32, and the two ends of the surface of one side of the mounting plate 31 are fixedly connected to the mounting frame 32, and the internal thread of one end surface of the mounting frame 32 is connected to the positioning bolt 33, and the middle position of the surface of one side of the mounting plate 31 is fixedly connected to a fixing sleeve 34, and the upper and lower end surfaces of the fixing sleeve 34 are provided with an insertion groove 35, and the surface of the fixing sleeve 34 is provided with a positioning groove 36 at the position of the insertion groove 35 on the side of the internal surface of the fixing sleeve 34, and the insertion groove 35 is connected to the interior of the positioning groove 36, and the two groups of insertion grooves 35 and positioning grooves 36 correspond to each other. A connecting pipe 37 is inserted into the interior of the middle position of the mounting plate 31 and the fixed sleeve 34, and a connecting sleeve 38 is fixedly connected to the outer surface of the connecting pipe 37, and positioning blocks 39 are fixedly connected to the inner wall surfaces of both ends of the connecting sleeve 38. The connecting sleeve 38 is sleeved on the outer surface of the fixed sleeve 34, and the inner wall surface of the connecting sleeve 38 is fitted with the outer surface of one end of the fixed sleeve 34. The width dimension of the outer side of the positioning block 39 is the same as the width dimension of the inner side of the insertion groove 35, and the position of the positioning block 39 corresponds to the position of the positioning groove 36. Figure 2 and Figure 6As shown, when the device is in use, when the connecting sleeve 38 is sleeved on the outer surface of one end of the fixed sleeve 34, the positioning block 39 is simultaneously inserted into the insertion groove 35, and at this time, rotating the connecting sleeve 38 can make the positioning block 39 move synchronously with the interior of the positioning groove 36, thereby preventing the connecting tube 37 from being separated from the breathing mask 1 when the connecting tube 37 is pulled by an external force;

[0028] The connecting sleeve 38 has threaded holes on both ends, and one end of the positioning bolt 33 is threadedly connected to the inside of the threaded hole. Figure 2 and Figure 6 As shown, when the equipment is in use, when the connecting sleeve 38 rotates the positioning block 39 to move to one end inside the positioning groove 36, the position of the threaded hole corresponds to the position of the positioning bolt 33. At this time, rotating the positioning bolt 33 can make one end of the positioning bolt 33 threadedly connected to the inside of the threaded hole, thereby positioning the position of the connecting pipe 37 and the connecting sleeve 38.

[0029] Working principle: When using the device, first open the patient's mouth, then put two sets of silicone tooth sleeves 24 on the outer surfaces of the upper and lower teeth inside the patient's mouth, respectively, while the silicone soft pad 25 is inside the patient's mouth. At this time, rotate the threaded rod 22 to move the fixing box 21 on the outer surface of the telescopic block 23, and drive the breathing mask 1 to move synchronously, so that the breathing mask 1 covers the patient's face, and the patient's mouth is supported by the two sets of silicone tooth sleeves 24 and the silicone soft pad 25, thereby preventing the breathing mask 1 from falling off through the support of the patient's teeth and the support structure 2.

[0030] When the device is in use, the outer surface of one end of the connecting tube 37 is passed through the interior of the fixing sleeve 34, the mounting plate 31, and the breathing mask 1 in sequence, so that the outer surface of one end of the connecting tube 37 is inserted into the interior of the patient's mouth, and the connecting sleeve 38 is sleeved on the outer surface of one end of the fixing sleeve 34. At this time, the positioning block 39 is synchronously inserted into the interior of the insertion groove 35, and then the connecting sleeve 38 is rotated to make the positioning block 39 move inside the positioning groove 36, and then the positioning bolt 33 is rotated inside the mounting frame 32 so that one end of the positioning bolt 33 is threadedly connected inside the threaded hole, thereby positioning the position of the connecting tube 37 and the connecting sleeve 38. In this way, the positioning structure 3 is used to prevent the connecting tube 37 from being easily separated from the breathing mask 1 when subjected to external force, and then oxygen is delivered to the patient's body through the air bag installed at the other end of the connecting tube 37. The above is the entire working principle of this utility model.
