Hemodialysis is one of the important renal replacement treatment means for the end-stage renal disease patients to live, and good vascular access is the premise and guarantee for the smooth proceeding of hemodialysis. Hemodialysis vascular access is roughly classified into temporary vascular access and long-term vascular access according to the length of use. The most common and preferred long-term vascular access in the clinic is an arteriovenous fistula. However, some patients have poor vascular conditions and cannot perform arteriovenous internal fistula operations or internal fistula occlusion, so that hemodialysis is difficult to perform for a long time. The clinical treatment measure for the part of patients is to perform hemodialysis by using a double-lumen catheter with a long-term terylene ring placed in the central vein. Such long-term catheters have a high incidence of infection relative to arteriovenous fistulas and vascular grafts, and the site of infection is concentrated primarily at the catheter exit and at the subcutaneous tunnel. Infection resistance at the catheter outlet is generally achieved by dressing change care, and subcutaneous tunnel care is generally achieved by inserting a scalp needle hose into a subcutaneous tunnel for irrigation.
