Description

Technical Field

[0001] The present invention relates to the technical field of medical drainage devices, and in particular to a hepatobiliary drainage device for general surgery in the medical field. Background Art

[0002] The hepatobiliary drainage device for general surgery in the medical field is an indispensable medical device in surgical treatment, especially important when dealing with hepatobiliary diseases. Patients with hepatobiliary diseases often have excessive internal pressure due to excessive fluid accumulation, and need to use a drainage device to drain the excess fluid to achieve the effect of decompression. The traditional hepatobiliary drainage device has a simple structure and inconvenient operation. Medical staff need to repeatedly operate the suction device, which is not only time-consuming and laborious, but also increases the workload of medical staff. Therefore, more advanced hepatobiliary drainage devices for general surgery in the medical field have been developed, aiming to improve the drainage efficiency, reduce the workload of medical staff, and ensure the safety and reliability of the drainage process. These devices are more user-friendly in design and function, making the drainage operation more convenient, and the patient's recovery process is thus smoother.

[0003] After retrieval, the patent with the Chinese patent number CN221257333U discloses a hepatobiliary drainage device for general surgery in the medical field. By setting a bottom plate, a reciprocating mechanism, a negative pressure drainage mechanism, a linkage rod, a liquid inlet pipe, a filtering mechanism, a drainage pipe, a liquid discharge pipe, and a liquid collecting cylinder, the reciprocating mechanism drives the negative pressure drainage mechanism to work. Two sets of negative pressure drainage mechanisms are arranged oppositely. When one set of negative pressure drainage mechanisms works to generate negative pressure to suck the liquid, the other set of negative pressure drainage mechanisms works to discharge the internal liquid. The negative pressure drainage mechanism sucks the drainage liquid in the patient's body into the internal through the liquid inlet pipe, and discharges the sucked drainage liquid into the liquid collecting cylinder through the liquid discharge pipe. The two sets of negative pressure drainage mechanisms alternate to perform the drainage operation, making the drainage operation continuous. The filtering mechanism filters blood clots and the like in the drainage liquid. Compared with the prior art, the patent with the Chinese patent number CN221257333U solves the problems that the structure of the existing hepatobiliary drainage device is too simple, it cannot quickly drain the liquid at the patient's affected area, the working efficiency is slow, usually medical staff need to continuously operate the suction device to extract the accumulated liquid, which increases the workload of medical staff, the operation is time-consuming and laborious, and it is not convenient for people to use.

[0004] However, in the actual use process of the above device, the bile in the liver can be continuously drained out through the negative pressure generating device. However, when the drainage ends and the negative pressure disappears, at this time, the air pressure difference between the liver and the drainage pipe changes, and backflow will occur. The drainage liquid may flow back, resulting in patient infection and affecting patient safety. Therefore, a hepatobiliary drainage device for general surgery in the medical field is proposed. Summary of the Invention

[0005] The object of the present invention is to solve the drawbacks in the prior art that through a negative pressure generating device, bile in the liver and gallbladder can be continuously drained out, but when the drainage ends and the negative pressure disappears, at this time, the air pressure difference between the liver and the drainage tube changes, resulting in backflow, and the drainage fluid may flow back, leading to patient infection and affecting patient safety.

The control mechanism drives a movable plate 22 arranged inside to rotate, regulating the flow rate of the drainage liquid during drainage. And a liquid outlet 13 is fixedly connected to the side of the filter housing 2 away from the liquid inlet 23. A connecting tube 4 is fixedly connected to the side of the liquid outlet 13 away from the filter housing 2. The other end of the connecting tube 4 is fixedly connected to a collection tank 5. A negative pressure generating mechanism is arranged at the lower part of the collection tank 5. The negative pressure generating mechanism controls the generation of negative pressure inside the collection tank 5;

[0036] Two rows of movable blades 24 are rotatably connected inside the liquid inlet 23. A filter net 15 is fixedly connected to the side of the filter housing 2 close to the movable blades 24. The two rows of movable blades 24 are cross-shaped blades arranged in a staggered manner, with the cutting edges facing the drainage tube 3 side, which can break blood clots. The control mechanism includes a valve housing 14 fixedly connected inside the filter housing 2. Two control housings 18 are fixedly connected to one side of the valve housing 14. A second motor 19 is arranged inside the control housing 18. A control component is arranged at the output end of the second motor 19. The control component includes a first gear 20 arranged at the output end of the second motor 19. The first gear 20 is meshed and connected with a second gear 21. The second gear 21 is rotatably connected between the control housing 18. The second gear 21 is fixedly connected with a movable plate 22. The movable plate 22 is rotatably connected between the valve housing 14. The movable plate 22 is designed to be inclined and can be opened in the direction of the movement of the drainage liquid. When the drainage liquid refluxes, it will drive the movable plate 22 to reverse and close inward;
