Abstract

The invention relates to the technical field of medical catheters, in particular to a hemodialysis medical catheter for dialysis and a preparation method of the hemodialysis medical catheter. The medical catheter comprises a catheter body and an antibacterial coating coated on the surface of the catheter body, wherein the catheter body is prepared from polyvinyl chloride plastic, modified filter residues, magnesium carbonate, silicon dioxide and ethidene diamine; and the antibacterial coating is prepared from copper powder and an anti-infection drug. Mulberry bark is used as a raw material, is treated by a propyl alcohol solution, and cooperates with the magnesium carbonate, the silicon dioxide and the ethidene diamine, so that the antibacterial performance of the medical catheter is improved. The antibacterial coating is prepared from anti-infection medicine raw materials and sprayed to the surface of the medical catheter, and the antibacterial performance of the medical catheter can be further improved.

Description

technical field [0001] The invention relates to the technical field of medical catheters, in particular to a hemodialysis medical catheter for kidney dialysis and a preparation method thereof. Background technique [0002] Medical catheter is a general term for lumen products that connect the inside and outside of the human body. It is widely used as a pathway in drainage, perfusion, drug administration, blood collection, blood transmission, detection of biological conditions through sensing elements, and auxiliary introduction of other medical devices. Commonly used medical catheters include hemodialysis catheters, central venous catheters, dialysis catheters, peripheral catheters with indwelling needles, arterial catheter sheaths, rapid exchange PTCA balloon dilation catheters, balloon endotracheal catheters, intraluminal stents, single and multi-lumen drainage and electrodes. Catheter etc. Medical catheters have become an indispensable tool in clinical medicine. At prese...
