Background
Hemodialysis is an important means of treating patients suffering from acute and chronic renal failure and some critical conditions. To avoid the problem of line clotting during treatment, doctors will administer a dose of anticoagulant to the patient's condition. However, due to the complexity of the patient's condition, there is still a case where a part of the treatment process is blocked by the blood filter or the venous vessel caused by the coagulation of the patient, and the patient cannot complete the whole treatment process, and the due treatment effect cannot be obtained.
The prior art solves the problem that the whole set of pipelines, including the blood filter and the whole set of dialysis pipelines, are replaced for patients to achieve the aim of continuous treatment. In blood purification treatment, blood filters or venous kettles are often combined with blood clotting. In actual use, even if coagulation occurs in either one of them, treatment cannot be continued. If serious coagulation occurs in both the blood filter and the venous kettle, the blood cannot be returned, and the whole set of pipelines needs to be replaced. During the replacement, the patient loses at least more than 100-150ml of blood; even if blood is smoothly returned to the patient, a water volume load of 200-250ml will be added to the patient, increasing the patient's treatment time and expense.
