This adopts a common connection method and is threadedly connected to the oxygen pipeline, ensuring a stable connection.

[0026] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, specifically, a nasal oxygen tube 4 passes through the upper end of the mask body 1. The nasal oxygen tube 4 includes a connecting tube 41, an insertion tube 42, a retaining ring 44, a sealing gasket 45, a connecting sleeve 46, and a sealing plug 47. The middle part of the connecting tube 41 is located inside the mask body 1. The outer wall of the mask body 1 is symmetrically provided with through holes 14. The connecting tube 41 passes through the through holes 14, and the middle part of the connecting tube 41 is symmetrically connected to the insertion tube 42 for insertion into the patient's nasal cavity for oxygen supply. The specific oxygen supply method can refer to the existing nasal oxygen tube oxygen inhalation method. The outer walls of both ends of the connecting tube 41 are symmetrically fixed with retaining rings 44. The inner wall of the through hole 14 is provided with a limiting groove 15, and the retaining ring 44 is located inside the limiting groove 15. On the side, a sealing washer 45 is fixed to the side wall of the retaining ring 44. The sealing washer 45 fits against the inner wall of the limiting groove 15. Both the retaining ring 44 and the sealing washer 45 are made of elastic material. The elastic material can tightly seal the plug hole 14 to ensure the airtightness of the mask, while not affecting the rotation of the nasal oxygen tube 4. The two ends of the connecting tube 41 are symmetrically connected to the connecting sleeve 46. The inner side of the connecting sleeve 46 is inserted with a sealing plug 47 for connecting to the external oxygen pipeline. This solution, through the oxygen tube 3 and the nasal oxygen tube 4, can achieve two oxygen inhalation methods coexisting through one mask. In actual use, it is convenient for medical staff to flexibly choose the use according to the actual oxygen inhalation needs of the patient, thus improving the practicality of the mask tool.

[0027] Reference Figure 7 As shown, specifically, a compression washer 461 is fixed to the inner wall of the connecting sleeve 46. The compression washer 461 is made of elastic material and can compress and limit the oxygen pipeline to be inserted later, thereby improving the stability of the insertion.

[0028] Example 2

[0029] In another embodiment of this solution, refer to Figure 2 and Figure 4As shown, specifically, the inner wall of the mask body 1 is provided with a connecting groove 11, and one side of the inner wall of the connecting groove 11 is provided with a threaded hole 12. The threaded hole 12 penetrates the side wall of the mask body 1, and a screw 6 is threadedly connected to the inner side of the threaded hole 12, which can be rotated and moved. The inner side of the mask body 1 is provided with an adjusting plate 5, and one side wall of the adjusting plate 5 is provided with a slot 51. The middle part of the connecting tube 41 is located inside the slot 51 and is used to position and store the nasal oxygen tube 4. The insertion tube 42 is located on both sides of the adjusting plate 5, which facilitates the rotation and storage of the insertion tube 42 and avoids the insertion tube 42 poking into the patient's face. One end of the screw 6 is inserted into the side wall of the adjusting plate 5, and a T-shaped rotating groove 52 is provided in the middle of one side wall of the adjusting plate 5, which does not affect the rotation. The rotation of screw 6 allows it to push the adjusting plate 5 to move. One end of screw 6 is fixed with a limiting plate 61, which is located inside the T-shaped rotating groove 52. When a patient needs to use nasal oxygen cannula 4 for oxygen inhalation, medical staff can rotate screw 6 to push the adjusting plate 5, causing the cannula 42 on nasal oxygen cannula 4 to be inserted into the patient's nasal cavity. At the same time, multiple slots 51 are provided on the adjusting plate 5 to facilitate adjustment of the engagement height of the cannula 42 on nasal oxygen cannula 4. Through the above settings, medical staff can easily move and adjust nasal oxygen cannula 4 according to the patient's actual facial (mouth and nose position) to ensure that the cannula 42 can be stably inserted into the patient's nasal cavity for oxygen supply. The adjustment operation is convenient.

[0030] Reference Figure 5 and Figure 6 As shown, specifically, a telescopic sleeve 13 is fixedly connected to the inner wall edge of the connecting groove 11. The telescopic sleeve 13 is located on the outer side of one end of the screw 6, and one end of the telescopic sleeve 13 is fixedly connected to the side wall of the adjusting plate 5.

The two ends of the connecting pipe 41 are symmetrically connected to telescopic tubes 43. The telescopic tubes 43 are located between the insertion tube 42 and the retaining ring 44, and can be stretched and retracted. Through the telescopic tubes 43, when the adjusting plate 5 pushes the nasal oxygen tube 4, the telescopic tubes 43 can stretch or retract with the change in position of the nasal oxygen tube 4, avoiding pulling on the end of the nasal oxygen tube 4. Through the above structure, the airtightness of the mask body 1 is improved, ensuring the effect of oxygen inhalation for the patient.

[0031] The working principle and usage process of this utility model are as follows: When a patient needs oxygen inhalation, the mask body 1 can be worn on the outside of the mouth and nose through the head strap 2. Medical staff can choose between high or low oxygen content modes according to the patient's actual oxygen needs. For example, when high oxygen content is required, medical staff can seal both ends of the nasal oxygen tube 4 on the mask through the sealing plug 47, and then thread the external oxygen pipeline and oxygen connector 3 to supply oxygen to the patient; when low oxygen content is required, medical staff can seal the oxygen connector 3 through the threaded cap 32, and then connect the oxygen pipeline and both ends of the nasal oxygen tube 4 to supply oxygen to the patient. The two oxygen supply modes can be flexibly switched, improving the convenience and practicality of the mask.

[0032] In addition, when using the nasal oxygen tube 4 to provide oxygen to patients, medical staff can lock the nasal oxygen tube 4 into the slots 51 at different positions on the adjusting plate 5 according to the specific position of the patient's nose, and rotate the screw 6 to push the adjusting plate 5 to move the nasal oxygen tube 4, so that the cannula 42 on the nasal oxygen tube 4 can be stably inserted into the patient's nasal cavity for oxygen supply, which is convenient to operate.
