DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] As Figures 1 to 4 shown, a drainage device for bile filtration includes a first drainage tube 1, a second drainage tube 2 threadedly installed below the first drainage tube 1, and a filter structure 4 arranged below the second drainage tube 2. A third drainage tube 3 is fixedly installed below the filter structure 4;

[0025] The filter structure 4 includes a connection bag 401. An inner filter bag 402 is fixedly installed inside the connection bag 401. A connection pipe 403 is fixedly installed at the top of the inner filter bag 402. The top of the connection pipe 403 is fixedly connected to the second drainage tube 2. One end of the inner filter bag 402 is fixedly installed with a shunt pipe 404.

[0026] Embodiment 2

[0027] In addition to all the technical features in the first embodiment, this embodiment further includes:

[0028] A connector 5 is fixedly installed at the end of the third drainage tube 3. A fourth drainage tube 6 is inserted below the connector 5. A collection bag 7 is fixedly connected below the fourth drainage tube 6. The connector 5 can connect the fourth drainage tube 6 and the collection bag 7 below the fourth drainage tube 6, so that the third drainage tube 3 forms a tight connection with the collection bag 7 below through the connector 5, avoiding the detachment of the third drainage tube 3 and the fourth drainage tube 6 during the collection process.

[0029] One end of the shunt tube 404 penetrates through the connection bag 401, and one end of the shunt tube 404 is fixedly connected to the collection bag 7. The shunt tube 404 can directly shunt a part of the filtered bile inside the inner filter bag 402 into the collection bag 7 during the filtration process of the inner filter bag 402, which can accelerate the bile collection speed.

[0030] Both the connection bag 401 and the collection bag 7 are made of transparent materials. The transparent connection bag 401 and the collection bag 7 can facilitate the user to observe the filtration situation of the inner filter bag 402 inside the connection bag 401 and the collection quality inside the collection bag 7.

[0031] Internal threads are provided on the inner side of the connector 5, and threads matching the connector 5 are provided at the connection between the fourth drainage tube 6 and the connector 5. The threads are provided on the outer side of the fourth drainage tube 6. The threads between the connector 5 and the fourth drainage tube 6 can prevent the disconnection of the insertion during the connection process of the connector 5 and the fourth drainage tube 6, and can also ensure the tightness during the connection of the two, avoiding bile leakage during bile flow.

[0032] Multiple groups of shielding soft plates 8 are provided at the top of the inner sides of the connector 5 and the fourth drainage tube 6, and the shielding soft plates 8 of the connector 5 and the fourth drainage tube 6 are arranged in a symmetric direction. The shielding soft plates 8 of the connector 5 are arranged upward, and the shielding soft plates 8 of the fourth drainage tube 6 are arranged downward. And the hardness of the shielding soft plates 8 at the connector 5 is greater than that of the shielding soft plates 8 at the fourth drainage tube 6. When the fourth drainage tube 6 is inserted into the connector 5, the fourth drainage tube 6 will be squeezed into the connector 5 from the shielding soft plates 8 inside the connector 5. During the bile drainage process, the bile will press down the shielding soft plates 8 by its weight and flow into the collection bag 7 below along the fourth drainage tube 6.

[0033] An outflow pipe 9 is fixedly installed below the collection bag 7. A fixed sleeve 10 is sleeved outside the outflow pipe 9. A limit nut 11 is fixedly installed outside the fixed sleeve 10. An adjustment screw 12 is threadedly installed in the middle of the limit nut 11. The outflow pipe 9 facilitates the discharge of bile inside the collection bag 7. During the process of the collection bag 7 discharging bile through the outflow pipe 9, the adjustment screw 12 can be turned at any time. Through the threaded connection between the adjustment screw 12 and the limit nut 11, the adjustment screw 12 can squeeze the outflow pipe 9 when turned, reducing the flow rate of the outflow pipe 9 or cutting off the flow.

[0034] Working principle: First, thread-connect the first drainage pipe 1 and the second drainage pipe 2. Then, insert the top end of the fourth drainage pipe 6 into the inside of the connector 5. When the fourth drainage pipe 6 is inserted into the inside of the connector 5, the fourth drainage pipe 6 will lift the shielding soft plate 8 inside the connector 5. Then, turn the connector 5 to thread-connect the connector 5 and the fourth drainage pipe 6. Subsequently, the drainage device can be used. During use, bile enters the inner filter bag 402 inside the connection bag 401 of the filtering structure 4 through the first drainage pipe 1 and the second drainage pipe 2. The inner filter bag 402 filters the drained bile. The filtered bile will fall into the inside of the connection bag 401 and be drained to the inside of the collection bag 7 through the third drainage pipe 3, the connector 5, and the fourth drainage pipe 6. At the same time, the shunt pipe 404 at the inner filter bag 402 will directly shunt the bile in the inner filter bag 402 to the inside of the collection bag 7, increasing the speed of bile collection in the collection bag 7. After collection is completed, unscrew the fourth drainage pipe 6 and the connector 5 and pull out the fourth drainage pipe 6 from the connector 5. At this time, since the shielding soft plate 8 is not squeezed, it will return to the upward shielding shape, which can prevent the outflow of bile for a certain period of time.
