[0025] In order to facilitate the adjustment of the swing amplitude of the second swing rod 13, thereby adjusting the speed of liquid suction, a placement bin 7 is provided below one end of the discharge tube 6, and a drainage bottle 18 is placed inside the placement bin 7. A slider 15 is rotatably connected to one side of the connecting block 19 through a pin shaft, and the surface of the slider 15 is slidably connected to the limiting groove 14. The internal thread of the connecting block 19 is connected to a screw rod 26, and the upper end of the screw rod 26 is fixedly connected to the first bevel gear 16, and the upper end of the first bevel gear 16 is meshedly connected to the second bevel gear 17.

[0026] In order to facilitate the treatment of fluid accumulation for different patients, a screw rod 24 is fixedly connected inside the second bevel gear 17, and one end of a connecting frame 25 is rotatably connected between the screw rod 24 and the lead screw 26. The drainage tube 5, the placement bin 7 and the motor 8 are all fixedly connected to the drainage box 1.

[0027] In order to facilitate the sterilization and disinfection of the surface of the drainage bottle 18 inside the placement bin 7 and effectively prevent bacterial cross infection, a piston rod 21 is fixedly connected to one side of the first rocker arm 12, and a piston cylinder 22 is slidably connected to the surface of the piston rod 21. The surface of the piston cylinder 22 is fixedly connected to a liquid storage box 23. The liquid storage box 23 is fixedly connected to the drainage box 1, and one end of the piston cylinder 22 passes through the interior of the placement bin 7.

[0028] In order to facilitate the smoothness of the operation of the device, the limit groove 14 is fixedly connected to the drainage box 1, a one-way valve is also provided inside the pipeline between the piston cylinder 22 and the liquid storage box 23, and the screw 24 is rotatably connected to the drainage box 1 through the limit plate.

[0031] After the installation of the utility model, the disinfectant is first added into the liquid storage box 23, and then the new drainage hose 3 is installed on the top of the drainage tube 5, and then the drainage bottle 18 is placed into the placement bin 7, so that one end of the drainage tube 6 is inserted into the drainage bottle 18, and then it is inserted into the position of the fluid accumulation in the patient's body, the motor 8 is started to rotate to drive the rotating shaft 9 to rotate, and the rotating shaft 9 rotates to drive the rotating plate 10 to rotate. When the rotating plate 10 rotates, the connecting rod 11 is driven to swing through the pin shaft, and the connecting rod 11 swings while the first swing rod 12 swings through the pin shaft. The first swing rod 12 swings and pulls the suction cup 20 at the other end to slide inside the drainage tube 5, so that the accumulated fluid in the patient's body can be sucked into the interior of the drainage tube 5 through the drainage hose 3. When the suction cup 20 slides inside the drainage tube 5 again, the accumulated fluid sucked in can be discharged to the interior of the drainage bottle 18 through the drainage tube 6 for collection, which can effectively prevent the accumulated fluid from leaking and causing harm to the surroundings;

[0032] At the same time, when the first swing arm 12 is swinging to extract the accumulated fluid, the swing of the first swing arm 12 can push the piston rod 21 to slide inside the piston cylinder 22, and the disinfectant liquid inside the liquid storage box 23 can be sprayed into the inside of the placement bin 7 through the liquid spray port, and the surface of the drainage bottle 18 inside the placement bin 7 can be sterilized and disinfected, which can prevent medical staff from directly contacting it when leakage occurs, avoid bacterial infection, and improve safety;

[0033] When the connecting rod 11 swings and drives the first swing rod 12 to swing through the pin shaft, the connecting rod 11 will also drive the second swing rod 13 to swing. The swing of the second swing rod 13 can limit the swing amplitude of the first swing rod 12. When it is necessary to discharge the effusion from different patients, the medical staff will rotate the screw rod 24. The rotation of the screw rod 24 drives the second bevel gear 17 set on the surface to rotate. The rotation of the second bevel gear 17 drives the first bevel gear 16 to rotate. The rotation of the first bevel gear 16 drives the screw rod 26 below to rotate inside the connecting block 19. The screw rod 26 can drive the screw rod 26 below to rotate while rotating. The slider 15 on one side of the connecting block 19 slides inside the limiting groove 14. When the slider 15 slides, the first bevel gear 16 rotates around the axis of the screw 24. Without affecting the movement of the connecting block 19 along the sliding trajectory of the slider 15, the connecting block 19 can drive the slider 15 on one side to slide inside the limiting groove 14. At this time, the connecting block 19 will drive one end of the second swing rod 13 to move through the pin shaft, changing the trajectory of the second swing rod 13 during movement, thereby affecting the sliding distance of the suction cup 20 inside the drainage tube 5. It can be suitable for different patients, has a wide range of use, and is safer.
