This catheter is used to provide vascular access for hemodialysis treatment. It is inserted into a large vein, usually in the neck, chest, or groin. The device allows blood to flow from the patient to the dialysis machine and back. It is made of soft, biocompatible material to reduce vessel irritation. There are temporary catheters for short-term use and tunneled catheters for long-term use. The catheter has two lumens for arterial and venous blood flow. It ensures efficient blood circulation during dialysis sessions. Proper placement is essential for effective dialysis.
