Background technique

In recent years, the incidence of uremia has been increasing but the awareness rate is low. Many patients are diagnosed with uremia when they are admitted to the hospital due to edema and fatigue, and need hemodialysis treatment. At this time, temporary vascular access needs to be established. Intravenous cannulation. The current temporary internal jugular vein catheter is fixed on the skin by sutures, and the outer section with a length of about 7 cm needs to be fixed with adhesive tape. The place where the temporary catheter enters the blood vessel through the skin needs to be covered with sterile gauze to prevent infection. Clinically, the outer section of the internal jugular vein temporary catheter used for hemodialysis is long and heavy. In the daily life of the patient, the tape or sterile gauze may easily fall off due to neck movement, which may cause bacteria to enter the blood and cause catheter-related bloodstream infection. In mild cases, it needs to be removed. Catheters, which can be fatal in severe cases leading to sepsis. The medical application currently used clinically can only cover the puncture site, and cannot take into account the outer section of the catheter.
