[0036] In the actual application process, refer to Figure 13The main pipeline 10 is used for communicating with the tracheal tube 40 to deliver oxygen to the patient, and one end of the main pipeline 10 is sealed by the sealing cover 50 in use, so that the air flow can flow to the patient, and the oxygen can be effectively utilized.

[0037] When the patient is in good condition, the following pipe blocking test is carried out, the air flow pipeline 20 is arranged on one side of the main pipeline 10, and the air flow adjusting assembly 30 is arranged on the air flow pipeline 20 to adjust the size of the air flow passage 201 in the air flow pipeline 20, so that the air flow in the air flow pipeline 20 can be gradually reduced, and the amount of oxygen supplied to the main pipeline 10 by the air flow pipeline 20 is controlled according to the rehabilitation condition of the patient, and the pipe blocking is tried from partial pipe blocking to gradual full pipe blocking; specifically, the air flow adjusting assembly 30 comprises a driving piece 310 and a fan-shaped adjusting valve body 320 arranged on the driving piece 310, the driving piece 310 is inserted on the air flow pipeline 20, and the fan-shaped adjusting valve body 320 is located in the air flow pipeline 20 and comprises a first sealing piece 321, a plurality of second sealing pieces 322 and a third sealing piece 323 which are sequentially sleeved on the driving piece 310; when the pipe blocking test is carried out, the driving piece 310 is rotated to drive the first sealing piece 321 to move and sequentially drive the plurality of second sealing pieces 322 to expand, so that the air flow passage 201 in the air flow pipeline 20 gradually becomes smaller, and partial pipe blocking to full pipe blocking is realized; in the pipe blocking test, the air flow adjusting assembly 30 is controlled to gradually reduce the air flow pipeline 20 according to the actual oxygen demand of the patient in the rehabilitation process, and the expansion angle of the fan-shaped adjusting valve body 320 is maximum after complete rehabilitation, so that the air flow pipeline 20 is closed to realize full pipe blocking, the self-breathing function of the patient is improved, and after complete sealing without discomfort, the tracheal tube pipe blocker and the tracheal tube 40 are pulled out together by the medical staff.

[0038] Of course, before the pipe blocking test, the air flow adjusting assembly 30 controls the air flow passage 201 to be in a fully open state, so as to ensure the amount of oxygen in the treatment process of the patient.

[0039] After the above pipe blocking test, if the patient has intolerance, the air flow adjusting assembly 30 can be controlled to open the air flow passage 201 correspondingly, so that the patient can inhale oxygen at any time.

[0040] As a preferred scheme of the embodiment, the expansion angle of the fan-shaped adjusting valve body 320 is θ, wherein 0°≤θ≤360°.

[0041] In the present embodiment, the opening angle of the fan-shaped regulating valve body 320 ranges from 0° to 360°. When the opening angle of the fan-shaped regulating valve body 320 is 0°, the airflow passage 201 of the airflow conduit 20 is fully open. As the opening angle gradually increases, the airflow passage 201 gradually decreases. When the opening angle of the fan-shaped regulating valve body 320 is 360°, the airflow passage 201 is fully blocked by the fan-shaped regulating valve body 320, and the gas cutting pipe plug is in the blocking state. The medical staff can pull out the gas cutting pipe plug together with the gas cutting pipe 40.

[0042] The Figure 7 In the present embodiment, the opening angle of the fan-shaped regulating valve body 320 ranges from 0° to 360°. When the opening angle of the fan-shaped regulating valve body 320 is 0°, the airflow passage 201 of the airflow conduit 20 is fully open. As the opening angle gradually increases, the airflow passage 201 gradually decreases. When the opening angle of the fan-shaped regulating valve body 320 is 360°, the airflow passage 201 is fully blocked by the fan-shaped regulating valve body 320, and the gas cutting pipe plug is in the blocking state. The medical staff can pull out the gas cutting pipe plug together with the gas cutting pipe 40.

[0043] In the plugging test, the size of the airflow passage 201 is adjusted by the airflow regulating assembly 30, and the opening degree symbol 221 changes as follows: from 1 / 4 to 2 / 4 to 3 / 4 to 4 / 4. After completing the full plugging, the plug and the gas cutting pipe 40 are pulled out together.

[0044] As a preferred scheme of the present embodiment, reference is made to Figures 3 to 10The driving member 310 comprises a rotating shaft 311, a sleeve 312 and a fixing block 313. The rotating shaft 311 is inserted into the airflow duct 20. The sleeve 312 is located in the airflow duct 20 and is sleeved on the rotating shaft 311. The fixing block 313 is located in the airflow duct 20 and is connected with the side wall of the sleeve 312, and a preset interval 301 is kept between the fixing block 313 and the rotating shaft 311. The first sealing sheet 321 comprises a first annular part 3211 and a mounting part 3212 which are connected with each other. The first annular part 3211 is sleeved on the rotating shaft 311. The mounting part 3212 is formed with a mounting gap 302. The fixing block 313 is clamped on the mounting gap 302. The outer periphery of the first annular part 3211 is provided with a first linkage block 3213. Each second sealing sheet 322 comprises a second annular part 3221 and a tab 3222 which are connected with each other. The second annular part 3221 is sleeved on the rotating shaft 311 in sequence and is located on the side of the first annular part 3211 away from the sleeve 312. The outer periphery of each second annular part 3221 is provided with a second linkage block 3223. The third sealing sheet 323 comprises a third annular part 3231 and a fixing part 3232 which are connected with each other. The third annular part 3231 is sleeved on the rotating shaft 311 and is located on the side of the second annular part 3221 away from the sleeve 312. The third annular part 3231 is connected with the airflow duct 20. The first linkage block 3213 protrudes the first annular part 3211 in the vertical direction and is used to push the tab 3222 or the second linkage block 3223 which are arranged adjacently. Each second linkage block 3223 protrudes the second annular part 3221 in the vertical direction and is used to push the next tab 3222 or the second linkage block 3223 which are arranged adjacently.

[0045] The driving member 310 is composed of a rotating shaft 311, a sleeve 312 and a fixing block 313. The rotating shaft 311 is inserted into the airflow duct 20. The first annular part 3211 of the first sealing sheet 321 is sleeved on the rotating shaft 311. The preset interval 301 provides a space for the arrangement of the first annular part 3211, so that the fixing block 313 can be clamped on the installation gap 302, and the first sealing sheet 321 is fixedly connected with the fixing block 313, so that the rotation of the rotating shaft 311 can drive the first sealing sheet 321 to move together. The second annular parts 3221 of the plurality of second sealing sheets 322 are sleeved on the rotating shaft 311 and are one by one abutted below the first annular part 3211. The third annular part 3231 of the third sealing sheet 323 is sleeved on the rotating shaft 311, and the third annular part 3231 abuts with the last second annular part 3221. The same preset interval 301 provides a space for the arrangement of the second annular part 3221 and the third annular part 3231. When the airflow adjusting assembly 30 is used, the first sealing sheet 321, all the second sealing sheets 322 and the third sealing sheet 323 are stacked together in the vertical direction when the airflow adjusting assembly 30 is in the initial position. At this time, the opening angle of the fan-shaped adjusting valve body 320 is zero, the airflow passage 201 in the airflow duct 20 is the largest, and the amount of oxygen passing through the airflow passage 201 is the largest. The rotating shaft 311 is rotated clockwise, driving the first sealing sheet 321 to move. The first linkage block 3213 can push the push edge 32221 of the adjacent second sealing sheet 322, so that the second sealing sheet 322 moves and expands under the action of the first linkage block 3213 and the rotating shaft 311. Similarly, the second linkage block 3223 of the second sealing sheet 322 can push the push edge 32221 of the adjacent second sealing sheet 322, so that the adjacent second sealing sheet 322 moves and expands in turn with the rotating shaft 311. According to the same principle, the opening angle of the fan-shaped adjusting valve body 320 increases in turn, and the airflow passage 201 gradually decreases, and the amount of oxygen passing through the airflow passage 201 also decreases, until the airflow duct 20 is fully blocked.

[0046] Conversely, the rotation shaft 311 is counterclockwise, the first sealing sheet 321 is driven to move, the first linkage block 3213 can drive the second linkage block 3223 of the second sealing sheet 322 arranged adjacent to the first linkage block 3213, so that the second sealing sheet 322 moves with the rotation shaft 311 and is folded under the action of the first linkage block 3213. Similarly, the second linkage block 3223 of the second sealing sheet 322 can drive the second linkage block 3223 of the second sealing sheet 322 arranged adjacent to the second linkage block 3223, so that the second sealing sheet 322 arranged adjacent to the second sealing sheet 322 moves with the rotation shaft 311 and is folded in turn. According to the above principle, the opening angle of the fan-shaped adjusting valve body 320 decreases in turn, the airflow passage 201 gradually increases, and the amount of oxygen passing through the airflow passage 201 also increases. In actual application, the rotation shaft 311 can be quickly controlled to realize the complete opening of the airflow pipe 20 to supply oxygen for the user's treatment.

[0047] As a preferred scheme of the embodiment, referring to Figures 2 to 8 , the airflow pipe 20 comprises a first pipe 210 and a second pipe 220 that are buckled with each other.
