Background

A central venous catheter for hemodialysis (abbreviated as a temporary catheter) is one of the vascular access for hemodialysis and other blood purification therapies. The principle is that a double-lumen catheter is placed into a central vein, one lumen of the double-lumen catheter is used as an arterial lumen for leading out blood, and the other lumen is used as a venous lumen for returning purified blood to a patient. The venous lumen opens at the distal end of the catheter and the arterial lumen opens at the side wall of the catheter near the distal end, which reduces recirculation during dialysis. The external part marks the arteriovenous cavities with red and blue colors respectively. The catheter is placed into the right jugular vein as the first choice, and is the most commonly used catheter placement site in clinic.
