The dialysis catheter serves as a conduit for blood to be removed from and returned to the patient’s body during hemodialysis. It allows for high blood flow rates necessary for effective dialysis, ensuring the efficient removal of waste products and excess fluids from the blood.
Components:
Key components of the dialysis catheter include:
• Lumens: Dual or triple lumens for simultaneous blood withdrawal and return, minimizing recirculation and ensuring effective dialysis.
• Tips: Specially designed tips (e.g., split-tip or step-tip) to optimize blood flow and reduce the risk of clotting and damage to blood vessels.
• Material: Bio-compatible materials to minimize the risk of infection and thrombosis, often coated with antimicrobial substances.
