When the device needs to be used, the medical staff pushes the device near a patient who can breathe independently. At this time, the medical staff puts the breathing mask that comes with the device on the patient's face. At this time, the compressed air machine 15 will start, and the compressed air machine 15 will discharge the oxygen inside the oxygen cylinder 17 into the inside of the trachea three 14 through the trachea four 16. The oxygen inside the trachea three 14 will enter the inside of the air bag 13. At this time, the air valve two 6 will be closed, and the air valve one 5 will be opened. The patient can absorb the oxygen inside the air bag 13 through the trachea one 3. At the same time, when the patient exhales, the air valve one 5 will be closed, and the air valve two 6 will be opened. The gas exhaled by the patient will be discharged into the inside of trachea 2 4 through trachea 1 3. When the patient is breathing independently, the medical staff can observe the expansion and contraction range of the airbag 13 through the glass window, and can timely understand the patient's breathing situation, which can improve the doctor's assessment of the timing of offline treatment for the patient and improve the patient's comfort.

When the device is used, the compressed air machine 15 discharges the oxygen inside the oxygen cylinder 17 into the inside of the trachea three 14. At this time, the oxygen inside the trachea three 14 will be compressed. The air machine 15 enters the air bag 13. When the patient inhales, the oxygen inside the air bag 13 will enter the inside of the trachea 3. At this time, the heating rod 806 will heat the surface of the trachea 3. When the oxygen enters the preheating area inside the trachea 3, the heating rod 806 can make the oxygen gentler when entering the patient's respiratory tract, which can prevent the patient's mucosa from drying out, thereby reducing the risk of respiratory tract infection in the patient. The preheating mechanism 8 also includes a connecting block 2 801, a push rod 802, and an elastic telescopic rod 807. The connecting block 2 801 is fixedly connected to the circumferential surface of the push plate 12, the push rod 802 is fixedly connected to the right side of the connecting block 801, the elastic telescopic rod 807 is fixedly connected to the inner wall of the box body 2, the connecting arc plate 805 is fixedly connected to the telescopic end of the elastic telescopic rod 807, the push rod 802 is in contact with the connecting arc plate 805, the heating rod 806 is in contact with the air pipe 3, and when the motor 7 is started, the reciprocating lateral movement of the push plate 12 can drive the connecting block 801 to move, and the connecting block 801 will drive the push rod 802 to move, and the push rod When 802 moves, the push rod 802 will squeeze and push the connecting arc plate 805. After being squeezed, the connecting arc plate 805 will compress the elastic telescopic rod 807, and the elastic telescopic rod 807 will expand and contract. At this time, the connecting arc plate 805 drives the heating rod 806 to move. After the heating rod 806 moves, it will not contact the surface of the trachea 3. At this time, the temperature of the oxygen entering the patient's body will be lower. At this time, the oxygen will have a certain stimulating effect on the patient after entering the patient's body, which can keep the patient awake.

[0017] Working principle: When the device needs to be used, the medical staff pushes the device to the vicinity of the patient who can breathe independently. At this time, the medical staff puts the breathing mask that comes with the device on the patient's face. At this time, the compressed air machine 15 will start, and the compressed air machine 15 will discharge the oxygen inside the oxygen cylinder 17 into the inside of the trachea three 14 through the trachea four 16. The oxygen inside the trachea three 14 will enter the inside of the airbag 13. At this time, the air valve two 6 will close, and the air valve one 5 will open. The patient can absorb the oxygen inside the airbag 13 through the trachea one 3. At the same time, when the patient exhales, the air valve one 5 will close, and the air valve two 6 will open. The gas exhaled by the patient will be discharged to the inside of the trachea two 4 through the trachea one 3. When the patient is breathing independently, the medical staff can observe the expansion and contraction range of the airbag 13 through the glass window, and can understand the patient's breathing situation in time, which can improve the doctor's assessment of the timing of offline treatment for the patient and improve the patient's comfort. When the patient's breathing amplitude and frequency are too low, the medical staff observes the amplitude of the airbag 13 to confirm that the patient is having difficulty breathing. At this time, the motor 7 The motor 7 will start, and the output end of the motor 7 will drive the reciprocating screw 10 to rotate. The rotation of the reciprocating screw 10 will drive the connecting block 11 to rotate, but at this time the connecting block 11 is restricted by the limit rod 18. At this time, the connecting block 11 can only move back and forth laterally through the reciprocating groove on the surface of the reciprocating screw 10. The movement of the connecting block 11 will drive the push plate 12 to move. During the movement of the push plate 12, the push plate 12 will contact and squeeze the airbag 13. The push plate 12 compresses the airbag 13 during the movement, which can assist the patient's inhalation to a certain extent. When the push plate 12 moves back and forth, the oxygen inside the trachea 3 14 will continue to enter the inside of the airbag 13, and the incoming oxygen can refill and reset. The reciprocating movement of the push plate 12 can adapt to the patient's respiratory rate, reduce the patient's work of breathing, allow the patient's respiratory muscles to get sufficient rest, further imitate the patient's respiratory rate, improve the patient's comfort, protect the respiratory muscles, improve gas exchange, and reduce the risk of barotrauma.

[0018] When the device is in use, the compressed air machine 15 discharges the oxygen in the oxygen cylinder 17 into the inside of the trachea three 14. At this time, the oxygen in the trachea three 14 will enter the air bag 13 through the compressed air machine 15. When the patient inhales, the oxygen in the air bag 13 will enter the inside of the trachea one 3. At this time, the heating rod 806 will heat the surface of the trachea one 3. When the oxygen enters the preheating area inside the trachea one 3, the heating rod 806 can make the oxygen gentler when entering the patient's respiratory tract, which can prevent the patient's mucosa from drying out, thereby reducing the risk of respiratory tract infection in the patient. When the motor 7 is started, the reciprocating horizontal movement of the push plate one 12 The upward movement can drive the connecting block 2 801 to move, and the connecting block 2 801 will drive the push rod 802 to move. When the push rod 802 moves, the push rod 802 will squeeze and push the connecting arc plate 805. After the connecting arc plate 805 is squeezed, it will compress the elastic telescopic rod 807, and the elastic telescopic rod 807 will be extended and retracted. At this time, the connecting arc plate 805 drives the heating rod 806 to move. After the heating rod 806 moves, it will not contact the surface of the trachea 3. At this time, the temperature of the oxygen entering the patient's body will be lower. At this time, the oxygen will have a certain stimulating effect on the patient after entering the patient's body, which can keep the patient awake.

At this time, the movable long plate 902 can only move through the reciprocating groove on the surface of the reciprocating screw rod 2 901. When the movable long plate 902 moves, the movable long plate 902 will drive the semi-arc sleeve 903 to move. After the semi-arc sleeve 903 moves a certain distance, the semi-arc sleeve 903 will contact the fixed arc plate 904. At this time, the semi-arc sleeve 903 and the fixed arc plate 904 will wrap the surface of the oxygen cylinder 17 and fix it.

When the dust cover 1 907 cannot move, the dust cover 1 907 will wrap the connection between the oxygen cylinder 17 and the trachea 4 16. At the same time, the medical staff will rotate the dust cover 2 908 and wrap the hinge of the other half. At this time, the dust and debris from the outside cannot adhere to the connection between the oxygen cylinder 17 and the trachea 4 16, so as to avoid dust from entering the oxygen cylinder 17 at the connection between the trachea 4 16 and the oxygen cylinder 17 when the oxygen cylinder 17 is replaced, thereby preventing dust and debris from irritating and damaging the patient's respiratory tract.
