Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a double bile duct drainage tube. Background Art

[0002] Percutaneous transhepatic biliary drainage is an important treatment for obstructive jaundice. However, existing biliary drainage tubes can only drain one side of the obstructed bile duct.

[0003] Patients with simultaneous obstruction of the left and right intrahepatic bile ducts due to a mass in the liver portal (for example, the tumor is located between the left and right intrahepatic bile ducts) require separate puncture and drainage of the dilated intrahepatic bile ducts on both sides. The two punctures not only increase the patient's pain but also increase the difficulty of drainage tube care. At the same time, during the second puncture, the tube can easily affect the first implanted tube during implantation, thus easily causing displacement and detachment of the first implanted tube. In view of this, a double biliary drainage tube is proposed to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a double biliary drainage tube, which can solve the problem that patients need to perform puncture and drainage on both sides of the dilated intrahepatic bile duct separately. The two punctures not only increase the pain of the patients, but also increase the difficulty of drainage tube care. At the same time, during the second puncture process, the tube can easily affect the tube implanted for the first time during the implantation process, thereby easily causing the first implanted tube to be displaced and fall off.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a double biliary drainage tube, comprising a first drainage pipe and a second drainage pipe, wherein the first drainage pipe and the second drainage pipe are arranged side by side, and the upper halves of the first drainage pipe and the second drainage pipe are fixedly bonded together;

[0006] An "α"-shaped positioning structure is wound around the lower half of the first drainage pipe;

[0007] The lower part of the second drainage tube is a pigtail-shaped loop;

[0008] The positioning structure is provided with a double-pipe drainage structure for draining the drainage liquid.

[0009] Preferably, drainage holes for allowing liquid to circulate are provided on the pigtail-shaped ring and the positioning structure of the first drainage pipe.

[0010] Preferably, the dual-pipe drainage structure includes a three-way connector, which is fixedly connected to the end of the positioning structure;

[0011] The positioning structure is in communication with a connection port of the three-way connector;

[0012] The other two ports of the three-way connector are respectively fixedly mounted with a first liquid drainage tube and a second liquid drainage tube;

[0013] The first liquid drainage tube and the second liquid drainage tube are also provided with drainage holes;

[0014] The second liquid drainage tube is provided with an inclined side wing. A drainage flow groove is opened on the second liquid drainage tube, and the drainage flow groove is located below the side wing.

[0015] Preferably, the first liquid drainage tube and the second liquid drainage tube are connected to each other through a three-way connector and a positioning structure on the first drainage pipe.

[0016] Preferably, the three-way connector is further provided with a sealing plug;

[0017] The sealing plug is mushroom-shaped.

[0018] Preferably, the inner walls of the other two ends of the three-way connector that are not in contact with the first drainage pipe are provided with fixing slots;

[0019] The fixed card slot is conical, and one end of the first liquid drainage tube and the second liquid drainage tube are both fixedly sleeved with a ring-conical fixed card block.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) When a double bile duct drainage tube is needed, the first liquid drainage tube and the second liquid drainage tube can be inserted into the interior of the three-way connector. At this time, the fixed card block made of rubber is deformed under force, so that the first liquid drainage tube and the second liquid drainage tube can smoothly enter the interior of the three-way connector. When the fixed card block moves to the position where the fixed card slot is located, it is restored by the elasticity of its own rubber material. Therefore, the fixed card block is inserted into the interior of the fixed card slot to fix the first liquid drainage tube and the second liquid drainage tube. At this time, the plane of the fixed card block and the plane of the fixed card slot conflict with each other, which can effectively prevent the first liquid drainage tube and the second liquid drainage tube from falling off, thereby ensuring normal drainage of the liquid.

[0022] (2) When a single drainage tube is needed for the double biliary drainage tube, the first liquid drainage tube or the second liquid drainage tube can be docked with the three-way connector as needed, and a sealing plug can be used to seal the interface where the drainage tube is not installed.

[0032] See also Figure 1-3 The utility model provides a technical solution: a double biliary drainage tube, comprising a first drainage pipe 1 and a second drainage pipe 2, the first drainage pipe 1 and the second drainage pipe 2 are arranged side by side, and the upper parts of the first drainage pipe 1 and the second drainage pipe 2 are fixedly bonded together;

[0033] The lower half of the first drainage pipe 1 is wrapped with an "α"-shaped positioning structure 3;

[0034] The lower half of the second drainage conduit 2 is in the form of a pigtail-shaped loop 9;

[0035] The positioning structure 3 is provided with a double-pipe drainage structure for draining the drainage liquid;

[0036] By fixing and bonding the upper halves of the first drainage tube 1 and the second drainage tube 2 together, the drainage tube is more convenient and quick to implant, and the phenomenon of ripple movement that occurs during the implantation of multiple single drainage tubes is avoided.

[0037] Furthermore, the pigtail-shaped ring 9 of the first drainage pipe 1 and the positioning structure 3 are both provided with drainage holes 10 for allowing liquid to circulate;

[0038] Furthermore, the dual-pipe drainage structure includes a three-way connector 4 , which is fixedly connected to the end of the positioning structure 3 ;

[0039] The positioning structure 3 is connected to a connection port of the three-way connector 4;

[0040] The other two ports of the three-way connector 4 are respectively fixedly mounted with a first liquid drainage tube 5 and a second liquid drainage tube 6;

[0041] The first liquid drainage tube 5 and the second liquid drainage tube 6 are also provided with drainage holes 10;

[0042] The second liquid drainage tube 6 is provided with an inclined side wing 7, and a drainage groove 8 is opened on the second liquid drainage tube 6, and the drainage groove 8 is located below the side wing 7;

[0043] The first liquid drainage tube 5 and the second liquid drainage tube 6 are connected to the positioning structure 3 on the first drainage pipe 1 through the three-way connector 4;

[0044] By providing a three-way connector 4 at the end of the positioning structure 3, the drainage tube can be simultaneously implanted into the patient's intestine and bile duct through the first liquid drainage tube 5 and the second liquid drainage tube 6 during the implantation process, thereby avoiding the phenomenon of the first implanted drainage tube being affected by the drainage of the later implanted drainage tube and being dislodged or displaced during the implantation of a single tube.

[0045] At the same time, the side wings 7 are provided to fix the second liquid drainage tube 6, so that the side wings 7 can come into contact with the inner wall of the intestine or bile duct, thereby fixing the second liquid drainage tube 6;

[0046] Furthermore, fixing slots 11 are provided on the inner walls of the other two ends of the three-way connector 4 that are not in contact with the first drainage pipe 1;

[0047] The fixed card slot 11 is conical, and a ring-conical fixed card block 12 is fixedly sleeved on one end of the first liquid drainage tube 5 and the second liquid drainage tube 6;

[0048] The fixed block 12 is made of rubber;

[0049] By setting the fixed block 12 to be annular and conical, and the fixed slot 11 to be conical, when double drainage tubes are needed, the first liquid drainage tube 5 and the second liquid drainage tube 6 can be inserted into the interior of the three-way connector 4. At this time, the fixed block 12 made of rubber is deformed under force so that the first liquid drainage tube 5 and the second liquid drainage tube 6 can smoothly enter the interior of the three-way connector 4. When the fixed block 12 moves to the position of the fixed slot 11, it is restored by the elasticity of its own rubber material. Therefore, the fixed block 12 is inserted into the interior of the fixed slot 11 to fix the first liquid drainage tube 5 and the second liquid drainage tube 6. At this time, the plane of the fixed block 12 and the plane of the fixed slot 11 conflict with each other, which can effectively prevent the first liquid drainage tube 5 and the second liquid drainage tube 6 from falling off, thereby ensuring normal drainage of the liquid.

[0050] Furthermore, a sealing plug 13 is provided on the three-way connector 4;

[0051] The sealing plug 13 is mushroom-shaped;

[0052] When a single drainage pipe is needed, the first liquid drainage tube 5 or the second liquid drainage tube 6 can be docked with the three-way connector 4 as needed, and the interface where the drainage tube is not installed can be sealed using a sealing plug 13.

[0053] Working principle: By providing a three-way connector 4 at the end of the positioning structure 3, the drainage tube can be simultaneously implanted into the patient's intestine and bile duct through the first liquid drainage tube 5 and the second liquid drainage tube 6 during the implantation process, thereby avoiding the phenomenon of the first implanted drainage tube being affected by the drainage of the later implanted drainage tube and being dislodged or displaced during the implantation process of a single tube.

[0054] By setting the fixed card block 12 to be annular and conical, and the fixed card groove 11 to be conical, when double drainage tubes are needed, the first liquid drainage tube 5 and the second liquid drainage tube 6 can be inserted into the interior of the three-way connector 4. At this time, the fixed card block 12 made of rubber is deformed under force so that the first liquid drainage tube 5 and the second liquid drainage tube 6 can smoothly enter the interior of the three-way connector 4. When the fixed card block 12 moves to the position where the fixed card groove 11 is located, it is restored by the elasticity of its own rubber material. Therefore, the fixed card block 12 is inserted into the interior of the fixed card groove 11 to fix the first liquid drainage tube 5 and the second liquid drainage tube 6. At this time, the plane of the fixed card block 12 and the plane of the fixed card groove 11 conflict with each other, thereby effectively preventing the first liquid drainage tube 5 and the second liquid drainage tube 6 from falling off, thereby ensuring normal drainage of the liquid;

[0055] When a single drainage pipe is needed, the first liquid drainage tube 5 or the second liquid drainage tube 6 can be docked with the three-way connector 4 as needed, and the interface where the drainage tube is not installed can be sealed using a sealing plug 13.

[0056] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
