What is Hemodialysis Catheter?

Working principle of hemodialysis catheter

The working principle of hemodialysis catheter is that after the catheter is inserted into the central venous system, the hemodialysis pipeline and dialysis machine are connected. The blood containing metabolic waste is inhaled from the arterial end of the catheter and passes through the circulation pipeline and dialysis machine. Through physical mechanisms such as dispersion, convection and adsorption, excess water and toxins in the body are removed, and the electrolyte and acid-base balance of patients are adjusted. The purified blood is pumped back to the central vein of the human body at the venous end of the catheter.

The composition and features of SCW hemodialysis catheter

SCW medicath Ltd. produces the disposable sterile hemodialysis catheter package.  The hemodialysis catheter of SCW medicath Ltd. is made of polyurethane (PU), which is in direct contact with the circulating blood of the human body, and the contact time shall not exceed 30 days. According to the classification catalogue of medical devices issued by the National Medical Products Administration. China,(NMPA) hemodialysis catheter package belongs to medical polymer material products, the management category is class III.

The catheter material has good compatibility, and the surface of the tube body is super slippery, which reduces the resistance of catheterization, effectively protects the inner wall of blood vessels, and prevents platelet adhesion and thrombosis.

The use of SCW hemodialysis catheter

The disposable sterile hemodialysis catheter package produced by SCW medicath Ltd. is mainly used for hemodialysis in emergency situations. The catheter package can be directly inserted into the central venous system through the internal jugular vein, subclavian vein and other large veins to ensure sufficient blood flow for effective dialysis. In the case of chronic renal failure/uremia, a permanent vascular pathway can be established through surgery, and the most commonly used is forearm arteriovenous fistula. Before each dialysis, arteriovenous fistula was punctured to establish a blood pathway. Compared with the consumables required for arteriovenous fistula puncture dialysis, the technical requirements and difficulty of the disposable sterile hemodialysis catheter package produced by SCW medicine Ltd. are much higher, and the safety and effectiveness of the product have been confirmed by clinical research.

In the case of chronic renal failure/uremia or long-term dialysis, more and more patients choose peritoneal dialysis, but peritoneal dialysis can not completely replace hemodialysis. In some emergency cases, such as life-threatening hyperkalemia, pulmonary edema and drug poisoning, hemodialysis catheters should be given priority.
