[0002] Dialysis is a treatment method that allows components in body fluids to be excreted from the body through a semipermeable membrane. Dialysis can be used to treat a variety of diseases, including chronic kidney disease, acute kidney injury, uremia, drug or poisoning, etc. Among them, the dialysis tube is an indispensable component. During dialysis, body fluids will flow from the patient's body through the dialysis tube to the dialysis machine. After dialysis, the body fluids will flow back into the patient's body through the dialysis tube. During the dialysis process, the dialysis tube joint may fall off due to the patient's movement, affecting the treatment and increasing the patient's pain.
