Background

Dialysis is one of the alternative treatments for renal failure that can be used to replace renal function for a long period of time. Dialysis can be divided into hemodialysis and peritoneal dialysis, wherein hemodialysis refers to the whole process of draining blood in vivo to the outside of the body for artificial purification and then returning the purified blood. Blood is usually drained into a dialyzer, and exchanges substances with dialysate outside hollow fibers in the dialyzer according to the principles of dispersion, ultrafiltration, adsorption and convection, so that metabolic waste and redundant water are removed, and the treatment purpose is achieved.

While hemodialysis is being performed on a patient, a vascular access needs to be established to the patient. The internal arteriovenous fistula of an autologous body is a commonly used dialysis method, and the specific operation is to respectively pierce internal fistula needles into arteriovenous veins of arms so as to carry out extracorporeal blood circulation. When the internal fistula needle needs to be pulled out after dialysis is finished, hemostasis and fixation are generally performed by common consumables such as a band-aid, a medical cotton ball, an elastic bandage, a tourniquet and the like. However, these consumables are not only inconvenient to operate, but also have relative movement of each part, and are difficult to achieve good hemostasis and fixation effects.
