Hemodialysis catheters are medical consumables designed for patients with acute and chronic renal failure to establish temporary or long-term extracorporeal blood circulation pathways to support dialysis treatment. During dialysis, the catheter safely draws the patient's blood out of the body, purifies it to remove metabolic waste and excess water through the dialysis machine, and then returns the clean blood to the body, effectively replacing part of the kidney function. This catheter is particularly suitable for patients who need emergency dialysis or cannot establish an arteriovenous fistula. With its convenient operation and stable blood flow characteristics, it has become an indispensable vascular access in maintenance dialysis treatment.
This catheter adopts a humanized soft-head cone design, which can be easily inserted into the blood vessel without a peelable catheter sheath, significantly reducing the damage to the blood vessel during insertion. The side hole is located 2.5 cm away from the end hole, which scientifically reduces blood bypass and blood vessel wall suction, thereby minimizing the risk of thrombosis. Its radiopaque material ensures clear development under X-ray, which is convenient for precise positioning and adjustment. The rotatable suture wing not only facilitates skin inspection, but also avoids catheter displacement and blood vessel wall adsorption, reduces the risk of exit infection, and prevents catheter kinking. The silicone extension tube design improves the patient's long-term comfort, is not easy to curl and deform, and the transparent tube body facilitates real-time observation of the liquid state.
To meet different clinical needs, the catheter is available in a variety of specifications such as single-lumen, double-lumen and triple-lumen. The application of medical polyurethane (PU) material makes it both flexible and anti-kink, ensuring the reliability of long-term use, and the pre-bent design further optimizes the wearing comfort. This hemodialysis catheter, which combines safety, comfort and functionality, provides patients with efficient and reliable treatment support.
