[0002] Bile duct drainage devices are mainly used to drain bile from the bile duct to the outside of the body to relieve the symptoms caused by biliary diseases and prevent the occurrence of complications. For some patients undergoing biliary surgery, a "T" - shaped drainage tube is placed at the incision of the common bile duct. The short arm is inserted into the bile duct, and the long arm passes through the abdominal wall and is fixed on the abdominal wall. The functions of the T - tube include: it can drain bile, reduce the pressure in the biliary tract, enable the bile duct suture to heal smoothly, and avoid bile fistula; it plays a supporting role in the biliary tract to avoid the formation of bile duct stenosis; and it serves as a channel for examining and treating biliary diseases.

[0003] Currently, during most biliary surgeries, usually medical staff directly connect the T - shaped drainage tube to the drainage bag for bile drainage. Therefore, there are the following disadvantages: the length of the drainage tube may not be sufficient to meet the patient's activity needs, resulting in restricted freedom and comfort for the patient. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bile duct drainage device to solve the problem that the length of the drainage tube may not be sufficient to meet the patient's activity needs, resulting in restricted freedom and comfort for the patient.

[0005] To achieve the above - mentioned utility model purpose, the utility model adopts the following technical solutions: A bile duct drainage device includes a connecting cylinder. The connecting cylinder is detachably arranged at the bottom end of the T - tube. The top of the connecting cylinder is provided with an external first thread. The top end of the connecting cylinder is detachably provided with a connecting cap. The top surface of the connecting cap is provided with a connecting hole. The T - tube is slidably inserted into the connecting hole.

The bottom of the connecting cylinder is provided with an external second thread. The bottom end of the connecting cylinder is detachably provided with a mounting cap. The bottom surface of the mounting cap is provided with a mounting hole. The inner wall of the mounting cap is provided with an internal second thread, and the internal second thread is threadedly connected with the external second thread. An abdominal drainage tube is slidably inserted into the mounting hole. The bottom end of the abdominal drainage tube is detachably provided with a drainage bag. The top surface of the drainage bag is connected and fixed with a connecting pipe, and the top end of the connecting pipe is in interference fit with the inside of the abdominal drainage tube.

[0006] Preferably, sealing rings are respectively sleeved on the top and bottom of the connecting cylinder.

[0008] Preferably, an observation hole is formed in the front side of the outer wall of the connecting cylinder, and a transparent plate is fixed to the inner wall of the observation hole.

[0009] Preferably, a scale is provided on the front side of the outer wall of the drainage bag.

[0010] Preferably, two hanging ears are fixed to the top surface of the drainage bag.

[0011] Compared with the prior art, the bile duct drainage device adopting the above technical scheme has the following beneficial effects:

[0012] First, during use, the connecting cylinder, connecting cap, and mounting cap facilitate the staff to connect the external drainage of the T-tube to the drainage bag, which can avoid the limitation of the patient's activities due to too short drainage tube, and prevent the separation, disconnection, and retrograde infection of the abdominal drainage tube and the T-tube during activities or unconscious pulling.

[0013] Second, during use, when the connecting cylinder, connecting cap, and mounting cap are tightly connected by threads, the sealing ring can effectively fill the tiny gaps between them, enhancing the sealing of the connection, preventing bile or other drainage fluids from leaking from the connection, and reducing the risk of infection. By setting the thickness of the sealing ring to 0.2 mm, it not only ensures the flexibility of the sealing ring so that it can closely fit the connection surface, but also ensures that it will not increase the difficulty of connection or affect the stability of the connection due to being too thick.

[0014] Third, during use, the observation hole and transparent plate facilitate medical staff or patient's family members to directly observe the color, properties, and flow rate of the drainage fluid, so as to timely judge the patient's drainage situation and provide a basis for medical decision-making. The scale enables medical staff to easily read and record the amount of drainage fluid, thus more accurately evaluating the patient's drainage effect and providing a reference for the adjustment of the treatment plan. The hanging ears facilitate medical staff to hang the drainage bag on the hospital bed or bracket, which not only maintains the stability of the drainage bag but also facilitates the patient's activities and the collection and treatment of the drainage fluid.
