The working principle of the hemodialysis catheter is that after the catheter is inserted into the central venous system, it connects the hemodialysis pipeline and the dialysis machine. The blood containing metabolic wastes of the dialysis patient is sucked from the arterial end of the catheter, passes through the circulation pipeline and the dialysis machine, through diffusion and convection And physical mechanisms such as adsorption, remove excess water and toxins in the body, adjust the patient’s electrolyte and acid-base balance, and the purified blood is pumped back into the central vein of the human body at the venous end of the catheter.

Zibo Dongmai's hemodialysis catheter tube is made of polyurethane (PU). The hemodialysis catheter is in direct contact with the circulating blood of the human body, and the contact time does not exceed 30. According to the classification catalog of medical devices issued by the State Food and Drug Administration, the hemodialysis catheter bag is a medical polymer material product, and the management category is Class III, which is a passive medical device.

The material of the catheter has good compatibility, and the surface of the tube body is treated with ultra-slip treatment, which reduces the resistance of the catheter, effectively protects the inner wall of the blood vessel, and prevents platelet adhesion and thrombosis. The color buckle is equipped with a white card with a specified flow rate to avoid errors during operation.

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

In the case of chronic renal failure/uremia or long-term dialysis, more and more patients choose peritoneal dialysis for convenience or economic reasons. However, peritoneal dialysis cannot completely replace hemodialysis. In some emergency situations such as life-threatening For patients with hyperkalemia, pulmonary edema, drug poisoning, etc., hemodialysis catheters should be given priority.
