[0002] Hemodialysis and peritoneal dialysis are the main renal replacement therapies for patients with renal failure besides kidney transplantation. Establishing an effective pathway is a prerequisite for the smooth progress of dialysis. Hemodialysis catheters and peritoneal dialysis catheters are one of the main pathways for patients with renal failure and need to be used for a long time, which also brings a lot of inconvenience to patients' lives.

[0003] When the existing clinical indwelling catheter is used, the connection between the indwelling catheter and the blood tube is often loose or the thread is not tightened during operation, causing bleeding. The connection between the indwelling catheter and the human body is covered with a gauze block and then fixed with tape, which does not provide a good protective effect. The tape is easy to spread during use, affecting the fixation of the gauze. When bleeding occurs, the existing device cannot alarm and notify the patient and the doctor in time.
