A movable plate 9 is fixedly arranged on the top of the telescopic spring 8, and the movable plate 9 is slidably arranged inside the liquid outlet pipe 6. A moving rod 10 is fixedly arranged on the top of the movable plate 9, and a buoyancy ball 11 is fixedly arranged on the top of the moving rod 10. The buoyancy ball 11 is a spherical structure, and the inside of the buoyancy ball 11 is hollow. The buoyancy ball 11 is made of plastic material, and the hollow buoyancy ball 11 made of plastic 1, making the buoyancy ball 11 lighter, thereby reducing the influence of the weight of the buoyancy ball 11 on the movable plate 9, the transverse cross-section of the moving rod 10 is circular, the moving rod 10 is made of plastic material, and the top of the moving rod 10 extends to the outside of the liquid outlet pipe 6, the moving rod 10 made of plastic is lighter, and the top of the moving rod 10 extends from the liquid outlet pipe 6, which is convenient for installing the buoyancy ball 11 on its top, and the drainage bottle 5 is pumped into a negative pressure state through an external negative pressure device, and the drainage liquid enters the drainage bottle 5. As the liquid level in the drainage bottle 5 rises, the buoyancy ball 11 is driven by the moving rod 10 The movable plate 9 is thereby moved out of the liquid outlet pipe 6, and the drainage fluid enters the drainage fluid collecting box 2 through the liquid outlet pipe 6. When the liquid level drops upward, the movable plate 9 re-enters the liquid outlet pipe 6 under the pull of the telescopic spring 8, and follows the rise and fall of the liquid level in the drainage bottle 5, so that the movable plate 9 repeatedly moves out of the liquid outlet pipe 6 and enters the liquid outlet pipe 6, thereby maintaining the liquid level of the drainage fluid within a certain range, thereby avoiding the situation where too much drainage fluid leads to the need to replace the drainage bottle 5, which easily causes the drainage fluid to flow back, thereby avoiding the situation where the patient's wound is infected due to the reflux of drainage fluid.

[0022] Specifically, the drainage liquid collection box 2 includes a liquid collecting box 21, which is placed on the top of the placement base 1. A mounting hole 22 is provided on the top of the liquid collecting box 21, and a liquid inlet pipe 23 is fixedly provided inside the mounting hole 22. An internal threaded pipe 24 is threadedly provided on the surface of the liquid inlet pipe 23, and the internal threaded pipe 24 is threadedly connected with the liquid outlet pipe 6. A discharge pipe 25 is fixedly provided on the left side of the liquid collecting box 21, and a discharge control valve is installed on the discharge pipe 25. A mounting slot 26 is provided on the front side of the liquid collecting box 21, and a liquid level observation window 27 is fixedly provided inside the mounting slot 26. The liquid level observation window 27 is made of a transparent acrylic plate material, and a scale line 12 is provided on the front side of the liquid level observation window 27. The scale line 12 is The degree values ​​increase from bottom to top, and the liquid level observation window 27 made of a transparent acrylic plate is not easy to be damaged, thereby avoiding the splashing of broken glass after the liquid level observation window 27 made of glass is damaged. The scale line 12 is convenient for observing the amount of liquid in the liquid collecting box 21, and when there is too much drainage liquid in the liquid collecting box 21, the drainage control valve is opened to discharge the drainage liquid through the drainage pipe 25. When the liquid collecting box 21 needs to be cleaned and disinfected, the internal threaded tube 24 is rotated to remove the internal threaded tube 24 from the liquid outlet pipe 6, and the liquid collecting box 21 can be removed from the top of the base 1, and the cleaning water and disinfectant are introduced into the liquid collecting box 21 through the liquid inlet pipe 23 to clean and disinfect the liquid collecting box 21.

[0023] Specifically, the drainage bottle 5 includes a bottle body 51, which is placed on the top of the top plate 4, and the liquid outlet pipe 6 is fixedly installed at the bottom of the bottle body 51. A bottle cap 52 is threadedly arranged on the surface of the bottle body 51, and a fixing hole 53 and a connecting hole 55 are penetrated through the top of the bottle cap 52. A drainage tube 54 is fixedly arranged inside the fixing hole 53, and a negative pressure tube 56 is fixedly arranged inside the connecting hole 55. Through the setting of the negative pressure tube 56, it is convenient for an external negative pressure device to extract the gas in the bottle body 51 through the negative pressure tube 56, so as to make the drainage bottle 5 in a negative pressure state. The bottle cap 52 is threadedly connected to the bottle body 51, which is convenient for installing the buoyancy ball 11 and cleaning and disinfecting the inside of the bottle body 51.

[0024] When in use: connect the negative pressure tube 56 to the external negative pressure device, and the external negative pressure device extracts the gas in the bottle body 51 through the negative pressure tube 56, so that the inside of the bottle body 51 is in a negative pressure state, so that the drainage liquid enters the inside of the bottle body 51 through the drainage tube 54. After the drainage liquid enters the inside of the bottle body 51, as the liquid level of the drainage liquid rises, the buoyancy ball 11 moves upward by buoyancy, and the buoyancy ball 11 drives the movable plate 9 to slide upward inside the liquid outlet pipe 6 through the moving rod 10, so that the movable plate 9 stretches the telescopic spring 8. When the movable plate 9 slides out of the liquid outlet pipe 6, the drainage liquid enters the inside through the liquid inlet end of the liquid outlet pipe 6 and passes through The liquid flows into the liquid inlet pipe 23 through the liquid outlet pipe 6, and enters the liquid collecting box 21 through the liquid inlet pipe 23. As the liquid level of the drainage liquid in the bottle body 51 drops, the movable plate 9 is pulled downward by the rebound of the telescopic spring 8, so that the movable plate 9 drives the buoyancy ball 11 to move downward through the moving rod 10. When the movable plate 9 enters the liquid outlet pipe 6, the liquid level of the drainage liquid in the bottle body 51 rises again, so that the buoyancy ball 11 drives the movable plate 9 to move out of the liquid outlet pipe 6 again through the moving rod 10, so that the movable plate 9 repeatedly enters and moves out of the liquid outlet pipe 6, thereby maintaining the liquid level of the drainage liquid in the bottle body 51 within a certain range.

[0025] To summarize, the hepatobiliary and pancreatic drainage device pumps the drainage bottle 5 into a negative pressure state through an external negative pressure device, and the drainage fluid enters the drainage bottle 5. As the liquid level in the drainage bottle 5 rises, the buoyancy ball 11 drives the movable plate 9 through the moving rod 10 to move out of the liquid outlet tube 6, and the drainage fluid enters the drainage fluid collection box 2 through the liquid outlet tube 6. When the liquid level drops upward, the movable plate 9 re-enters the liquid outlet tube 6 under the pull of the telescopic spring 8, and follows the rise and fall of the liquid level in the drainage bottle 5, so that the movable plate 9 repeatedly moves out of the liquid outlet tube 6 and enters the liquid outlet tube 6, so that the liquid level of the drainage fluid is maintained within a certain range, thereby avoiding the situation where too much drainage fluid causes the replacement of the drainage bottle 5, which easily causes the drainage fluid to reflux, thereby avoiding the situation where the patient's wound is infected due to the reflux of the drainage fluid, and is used to solve the problems raised in the above-mentioned background technology.
