When the gas inside the housing 8 is discharged into the inside of the liquid storage tank 18 through the second one-way pipe 19, the design of the second one-way pipe 19 ensures that the gas can only flow in one direction, preventing backflow during the discharge of the gas, and allowing the discharged gas to be discharged only from the exhaust valve 182.

[0026] As shown in Figure 1 and Figures 3-5 , the protection mechanism includes an air bag 12, a rubber ring 121, an air inlet valve 13 and an exhaust assembly. The air bag 12 of the sleeve structure is sleeved on the outer wall of the front end of the extension pipe 11, and the front part slightly exceeds the extension pipe 11. When the extension pipe 11 is inserted into the deep part of the respiratory tract of the patient, the air bag 12 provides a soft and adaptable sealing interface for the respiratory tract of the patient, and the air bag 12 is made of polyurethane, which is more wear-resistant than silicone, while maintaining good flexibility and elasticity. And the smooth surface of polyurethane can reduce friction or collision with the respiratory mucosa, providing a more comfortable experience. The rubber ring 121 is connected to the rear part of the air bag 12 by a fixed connection, and the air inlet valve 13 is connected to the rear part of the air bag 12 by a fixed connection. The rubber ring 121 covers the air inlet valve 13 to prevent the air inlet valve 13 from being exposed to the respiratory tract of the patient and causing discomfort. The exhaust assembly for discharging the gas inside the air bag 12 is arranged at the rear part of the air bag 12.

[0027] As shown in Figure 1 , Figure 3 and Figure 4As shown, the exhaust assembly includes an exhaust pipe 14, a second spring 141, a ball valve 142, a connecting plate 143, a top column 144, a third spring 145 and a cover plate 146. The exhaust pipe 14 is connected to the rear of the air bag 12 by a fixed manner and is located below the air inlet valve 13. The rubber ring 121 covers the exhaust pipe 14 to prevent the exhaust pipe 14 from being exposed to the respiratory tract of the patient. The ball valve 142 is slidingly connected to the inside of the exhaust pipe 14. The second spring 141 is connected between the exhaust pipe 14 and the ball valve 142 by a fixed manner. The connecting plate 143 is connected to the inside of the exhaust pipe 14 by a fixed manner. The top column 144 is slidingly connected to the connecting plate 143 in a penetrating manner. The front end of the top column 144 is in a hemispherical structure and is in contact with the center of the spherical surface of the rear end of the ball valve 142. The surface of the hemispherical structure is tightly fitted with the spherical surface of the rear end of the ball valve 142 to ensure the stability of the contact. The third spring 145 is connected between the connecting plate 143 and the top column 144 by a fixed manner. The cover plate 146 is rotatably connected to the rear end of the exhaust pipe 14. The rear end of the top column 144 is in contact with the cover plate 146. There is enough friction coefficient between the cover plate 146 and the exhaust pipe 14 to ensure that the cover plate 146 is not easily rotated and the exhaust pipe 14 is not easily opened under normal conditions even if it is subjected to slight external force.

[0028] As shown in Figure 1 and Figure 2 The trigger 2 is rotatably connected to the mounting frame 1. The push rod 3 is connected to the upper part of the trigger 2 by a fixed manner. The push plate 4 is connected to the outside of the piston rod 6 by a fixed manner. The push rod 3 is located behind the push plate 4 and can accurately extrude the push plate 4. The first spring 5 is connected between the push plate 4 and the shell 8 by a fixed manner and is sleeved outside the piston rod 6. When the piston rod 6 moves forward, the first spring 5 is compressed to store energy. When the piston rod 6 is released, the first spring 5 releases energy to assist the piston rod 6 to move backward to the original position.

[0029] When it is necessary to discharge sputum from the patient, the medical staff uses a small air pump to send gas into the air bag 12 through the air inlet valve 13 (the air inlet valve 13 is automatically opened by the gas pressure). With the sending of the gas, the air bag 12 gradually expands. When the expansion is appropriate, the gas sending is stopped and the air inlet valve 13 is automatically closed.

[0030] When the gas in the air bag 12 is too much, rotate the cover plate 146 clockwise by 180 degrees, expose the top post 144, then push the top post 144 forward, the third spring 145 is compressed, in turn, extrude the ball valve 142 to move forward to open the exhaust pipe 14, the second spring 141 is compressed, the gas in the air bag 12 is discharged from the exhaust pipe 14, when the appropriate amount of gas is discharged, the air bag 12 is in the appropriate size, immediately release the top post 144, the third spring 145 returns to its original state, prompting the top post 144 to move back to the initial position, stop extruding the ball valve 142, the second spring 141 returns to its original state, prompting the ball valve 142 to move back to the initial position, close the exhaust pipe 14, and then rotate the cover plate 146 counterclockwise by 180 degrees to block the top post 144 and seal the exhaust pipe 14;

[0031] Then press the trigger 2 to drive the push rod 3 to move forward, extrude the push plate 4 to move forward, the piston rod 6 drives the piston block 7 to move forward with the push plate 4, the first spring 5 is compressed, when the piston block 7 moves forward, the positive pressure is generated in the shell 8, in turn, extruding the gas in the shell 8 through the conical cover 9, the discharge pipe 102 and the second one-way pipe 19 into the liquid storage tank 18, when the piston block 7 moves to the limit position, close to the conical cover 9;

[0032] Then turn on the illuminating lamp 15 and the pinhole camera 16, and instruct the patient to open the oral cavity. Insert the extension tube 11 into the respiratory tract through the patient's oral cavity. In this process, the illuminating lamp 15 provides sufficient light to clearly observe the situation in the patient's respiratory tract. The pinhole camera 16 real-time shoots the picture in the respiratory tract and feeds back the shot picture to the display screen 17. By watching the picture on the display screen 17, the position of the sputum can be accurately judged. At the same time, the air bag 12 continuously wraps around the extension tube 11 to adapt to the patient's respiratory tract, reducing the friction or collision with the respiratory tract mucosa;

[0033] When the extension tube 11 is aligned with the sputum, release the trigger 2, the first spring 5 returns to its original state, prompting the push plate 4 to move back to the initial position, the piston rod 6 drives the piston block 7 to move back with the push plate 4, when the piston block 7 moves back, the negative pressure is generated in the shell 8, in turn, generating suction force on the extension tube 11 to suck the sputum in the patient's respiratory tract, the sucked sputum flows into the shell 8 through the conical pipe 101 and the first one-way pipe 10, and is blocked by the conical cover 9 to avoid contaminating the moving area of the piston block 7. Thus, one sputum suction process is completed.

[0034] Finally, repeat the above steps to continue the sputum suction operation. In the sputum suction process, the sputum sucked into the shell 8 last time will be discharged from the discharge pipe 102 and the second one-way pipe 19 into the liquid storage tank 18 when the next sputum suction is performed. With more and more gas and sputum being discharged into the liquid storage tank 18, the overpressure gas in the liquid storage tank 18 is discharged from the exhaust valve 182, thereby maintaining the pressure balance in the liquid storage tank 18.

[0035] While the present application has been described with reference to exemplary embodiments, it is to be understood that the application is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the widest patent protection allowable under the law.
