A guide pipe b4 is provided between the lavage fluid tank 2 and the syringe 14 to guide the flow of lavage fluid. When performing lavage operation on the alveoli of small animals, the small animal is first fixed on the operating table and anesthetized. , then insert the return pipe 15 and the outlet pipe 16 at the lower end of the syringe 14 into the mouth of the small animal to the position of the alveoli, then start the controller 5 on the syringe 14, the controller 5 guides the oxygen and lavage fluid inside the oxygen tank 1 and the lavage fluid tank 2 to move synchronously, and spray them synchronously from the outlet pipe 16, lavaging the alveoli while providing oxygen, and the waste liquid generated during the lavage process will flow back through the return pipe 15 and be guided to the waste liquid tank 12 for collection. After waiting for a certain period of time, the lavage operation can be stopped after the lavage fluid discharged from the guide tube c19 is clean and transparent, the syringe 14 can be removed from the small animal's mouth, and the small animal can be waited for to wake up;

[0028] A temporary storage bubble 18 is provided inside the guide tube c19, and a movable ring 24 is provided on the lower side of the temporary storage bubble 18. The outer wall of the left end of the movable ring 24 is fixedly connected to a threaded rod 21, and the outer wall of the left end of the threaded rod 21 is fixedly connected to a handle 20 to drive the movable ring 24 to rotate under the action of external force to block the guide tube c19. When the waste liquid tank 12 is full and needs to be replaced, the handle 20 can be rotated clockwise to make the threaded rod 21 drive the movable ring 24 to rotate, blocking the guide tube c19 to prevent the guide tube c19 from dripping waste liquid after being pulled out. During the movement, the waste liquid flowing inside the guide tube c19 can be temporarily stored inside the temporary storage bubble 18. After inserting a new waste liquid tank 12, the handle 20 can be rotated counterclockwise to reopen the movable ring 24 to allow the waste liquid to flow from the guide tube c19 to the inside of the new waste liquid tank 12.

[0029] like Figure 3 and Figure 4 As shown, the circular outer wall of the left end of the guide tube c19 is fixedly connected to a fixed block 22 to limit the position of the threaded rod 21. A threaded hole 23 is opened inside the fixed block 22 to pass through the left and right sides. The circular outer wall of the movable ring 24 is fixedly connected to a leak-proof pad 25, which is made of soft rubber material.

[0030] The threaded hole 23 can limit the position of the movable ring 24 when the threaded rod 21 is not rotating, thereby preventing the movable ring 24 from being offset due to the influence of the circulating waste liquid. The leak-proof pad 25 can increase the filling tightness between the movable ring 24 and the inner wall of the guide tube c19 to avoid leakage.

[0031] like Figure 3 and Figure 4 As shown, when the threaded rod 21 rotates clockwise 90 degrees, the movable ring 24 can be changed from vertical to horizontal to block the flow of irrigation fluid. When the threaded rod 21 rotates counterclockwise 90 degrees, the movable ring 24 can be changed from horizontal to vertical to allow the irrigation fluid to continue to flow.

[0032] By rotating in clockwise and counterclockwise directions, the movable ring 24 can block and clear the waste liquid inside the guide tube c19.

[0034] The photoelectric element 7 can illuminate the area of ​​the liquid outlet pipe 16 through the camera and searchlight at the lower end of the syringe 14, and transmit the image to the terminal for medical staff to watch and make subsequent judgments and operations. At the same time, the regulating valve c17 can limit the speed and amount of oxygen discharged from the oxygen tank 1. The regulating valve a6 can control the flow rate and flow velocity of the irrigating fluid to avoid damage to the alveoli caused by excessive flow rate. The regulating valve b13 can control the speed of waste liquid return.

[0035] like Figure 1 As shown, the upper outer wall of the syringe 14 is fixedly connected to the power cord 8, the other end of the power cord 8 is fixedly connected to the regulator 9, the front outer wall of the regulator 9 is embedded with a display screen 10 near the upper side, and the front outer wall of the regulator 9 is provided with multiple control knobs 11 near the lower side.

[0036] The sizes of the valve core openings inside the regulating valves a6, b13 and c17 can be controlled by adjusting the multiple control knobs 11 at the front end of the regulator 9. The sizes of the valve core openings inside the regulating valves a6, b13 and c17 can be viewed through the display screen 10. The power cord 8 can be used to control the electrical supply between the controller 5 and the regulating valves a6, b13 and c17.

[0037] The implementation principle of this embodiment is as follows: when performing alveolar lavage on a small animal, the small animal is first fixed on the operating table and anesthetized, and then the return pipe 15 and the outlet pipe 16 at the lower end of the syringe 14 are inserted into the mouth of the small animal to the position of the alveoli, and then the controller 5 on the syringe 14 is started. The controller 5 guides the oxygen and lavage liquid inside the oxygen tank 1 and the lavage liquid tank 2 to move synchronously, and spray out synchronously from the outlet pipe 16, lavaging the alveoli while providing oxygen, and the waste liquid generated during the lavage process will flow back through the return pipe 15 and be guided to the waste liquid tank 12 for collection. After waiting for a certain period of time, the lavage liquid discharged from the guide pipe c19 is discharged. After the liquid is clean and clear, the irrigation operation can be stopped, the syringe 14 can be taken out from the mouth of the small animal, and the small animal can be waited for to wake up. When the waste liquid tank 12 is full and needs to be replaced, the handle 20 can be rotated clockwise to make the threaded rod 21 drive the movable ring 24 to rotate, blocking the guide tube c19 to prevent the guide tube c19 from dripping waste liquid after being pulled out. During the movement, the waste liquid flowing inside the guide tube c19 can be temporarily stored inside the temporary bubble 18. After inserting the new waste liquid tank 12, the handle 20 can be rotated counterclockwise to reopen the movable ring 24 to allow the waste liquid to flow from the guide tube c19 to the inside of the new waste liquid tank 12.
