Specifically, the locking member 223 has a width greater than the thickness of the fixing tube 226.
Specifically, the limiting structure 224 is a C-shaped clamp spring (not shown in the figure). Correspondingly, the outer side wall of the fixing tube 226 is provided with a mounting groove matched with the C-shaped clamp spring. During assembly, the reset structure 222 and the sliding sleeve 221 are sequentially mounted on the outer side of the fixed tube 226, then the sliding sleeve 221 is pushed towards the mask 1 to expose the mounting groove, and then the limiting structure 224 is mounted on the outer side wall of the fixed tube 226 by using the snap spring clamp to prevent the sliding sleeve 221 and the reset structure 222 from being separated from the fixed tube 226.
In some embodiments of the present application, the return structure 222 is a linear compression spring.
As shown in fig. 6, when there is no external force, the restoring structure 222 presses the sliding sleeve 221 against the side wall of the position-limiting structure 224, and the locking member 223 protrudes from the inner side wall of the fixed tube 226 under the pressing force of the sliding sleeve 221.
In some embodiments of the present application, to ensure that the axial center of the first end 232 coincides with the axial center of the fixing tube 226 after fixing, the number of locking members 223 is A, and A ≧ 3.

Method and principle of securing first end 232 using locking assembly 22:
s1, pushing the sliding sleeve 221 towards the direction close to the face mask 1 to compress the reset structure 222, wherein the locking piece 223 is not pressed by the sliding sleeve 221 any more, and the locking piece 223 can freely slide in the slideway;
s2, inserting the first end 232 into the fixed pipe 226, and enabling the side wall of the first end 232 to jack up the locking member 223 to enable the locking member 223 to move towards the direction of the sliding sleeve 221 along the slide way;
and S3, releasing the sliding sleeve 221, pressing the locking member 223 on the side wall of the first end 232 by the sliding sleeve 221 under the pushing of the resetting structure 222, and continuing to push the first end 232 to move towards the inside of the fixed tube 226 until the locking member 223 is clamped into the locking groove 234, wherein the first end 232 is locked in the inside of the locking assembly 22.
Method and principle of disengaging the locking assembly 22 from the first end 232:
s1, pushing the sliding sleeve 221 towards the direction close to the mask 1 to compress the reset structure 222, wherein the locking piece 223 is not pressed by the sliding sleeve 221 any more, and the locking piece 223 can freely slide in the slideway;
s2, pulling the first end 232 reversely to enable the locking member 223 to be disengaged from the locking groove 234;
s3, the sliding sleeve 221 is released, the sliding sleeve 221 is pressed on the side wall of the first end 232 under the pushing of the reset structure 222, and the first end 232 continues to be pulled until the first end 232 completely leaves the fixed tube 226.
In summary, the locking assembly 22 and the first end 232 can be used to quickly connect the fixing structure 21 and the oxygen supply tube 23. After the patient wears the mask 1, the oxygen supply pipe 23 is quickly connected to the mask 1, and the pathway between the mask 1 and the external oxygen supply device is communicated before the patient consumes oxygen in the mask 1, so that the danger caused by oxygen deficiency in a short time is prevented.
As shown in fig. 3, the intervening portion 4 includes a guide structure 41 and a seal cover 43; one end of the guiding structure 41 is fixedly connected with the face mask 1, the other end is detachably connected with the sealing cover 43, and the inside of the guiding structure 41 is fixedly connected with the one-way structure 42.
Specifically, the one-way structure 42 is a horn-shaped structure made of rubber material, and a contraction end of the one-way structure 42 faces the mask 1. During the bronchoscopic operation, the sealing cover 43 is opened first, and then the doctor holds the bronchoscope to enter the inside of the face mask 1 through the one-way structure 42 and insert the nasal cavity of the patient. The outer wall of bronchoscope is hugged closely to the shrink end, because rubber materials possesses elasticity, and in the operation process, bronchoscope props the shrink end greatly gradually, and makes bronchoscope can get into patient's trachea gradually. And during surgery, the patient's exhaled air cannot pass through the one-way structure 42 into the outside air.
As shown in fig. 2-3 and 5-6, the face mask 1 comprises a wearing frame 11, a transparent cover 12 and a fixing belt 13; the inner side of the wearing frame 11 is connected with the transparent cover 12, and the outer side is connected with the fixing belt 13; when the mask 1 is worn, the fixing belt 13 fixes the wearing frame 11 on the head of a patient, so that the wearing frame 11 is tightly attached to the skin of the patient, and a cavity is formed between the transparent cover 12 and the face of the patient.
The oxygen supply part 2 and the filter part 3 are communicated with the cavity. The oxygen supply unit 2 introduces oxygen supplied from an external oxygen supply device into the cavity so that the oxygen content in the cavity is higher than that in the atmosphere. Blocking the way of preventing the pathogen in the lung from spreading out of the face mask 1 in the form of aerosol when the patient coughs, preventing the pollution to the environment and protecting the medical staff at the same time. The filtering part 3 filters the gas exhaled by the patient and then discharges the gas to the outside of the face mask 1, thereby blocking the way of preventing the pulmonary pathogens from being transmitted to the outside of the face mask 1 in the form of aerosol when the patient coughs, preventing the environment from being polluted and protecting the medical staff.
Preferably, a sealing layer 14 is arranged on the side of the wearing frame 11 facing the skin of the patient, so that the air tightness of the cavity is enhanced, and the gas exhaled by the patient is prevented from being exhausted through a gap between the wearing frame 11 and the skin of the patient.
In some embodiments of the present application, a filtering membrane is disposed inside the filtering portion 3, the filtering membrane is detachably connected to the filtering portion 3, and the gas exhaled by the patient is filtered by the filtering membrane and then discharged to the outside of the mask 1.
The application method of the embodiment comprises the following steps:
s1, installing a filtering membrane into the filtering part 3;
s2, the mask 1 is worn on the head of a patient and the face of the patient is wrapped inside;
s3, the oxygen supply part 2 is connected with external oxygen supply equipment;
s4, opening the sealing cover 43 to start the bronchoscope operation.
Example 2
As shown in fig. 2 to 8, the present embodiment is different from embodiment 1 in that:
