[0002] During hemodialysis, the patient's blood needs to be drawn out of the body and connected to the dialysis circuit and dialyzer through an extracorporeal device to complete the dialysis treatment. During this process, when the blood leaves the human body and runs outside the body, it is easy to cause blood coagulation or thrombosis. Since the venous pot of the dialysis pipeline is equipped with a filter, on the one hand, it can filter out thrombi, but on the other hand, it is easy to cause thrombi to aggregate and cause pipeline blockage, and the blood cannot be smoothly returned to the body. Therefore, due to its particularity, in clinical practice, the probability of venous pot blockage during hemodialysis is the most common. In clinical practice, when the venous pot is blocked, the existing blood circuit tube has the following deficiencies during use.

[0003] However, the existing device has the following problems when it is actually used:

[0004] 1. As the only blood transfusion channel, when blockage occurs, blood cannot be transfused back into the body, resulting in the inability to continue dialysis treatment and the patient losing a large amount of blood, which has the most serious consequences;

[0005] 2. It takes a certain amount of time to replace the dialysis line. During this process, the blood stagnation time is prolonged, the occurrence of blood coagulation is aggravated, and it is easy to cause emergencies;

[0006] 3. During the process of replacing the dialysis tubing, various pipe openings are in an open state, which is easy to cause contamination;
