Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a multifunctional coating suitable for urinary medical devices, its preparation method and application. Background technique

[0002] Bacterial infection and crust formation are common complications during the implantation / intervention of urological medical devices. UTIs are the most common nosocomial infection after respiratory and bloodstream infections. Catheter-related urinary tract infections have been reported in up to 98% of intensive care unit urinary tract infections. When urinary medical devices are implanted in the body as a foreign body, a layer of urine conditioning film will be rapidly formed on the surface, including lipids, proteins, inorganic salts, etc. stone. When bacteria exist, bacterial metabolites such as polysaccharides and mucins can form biofilms, which can coagulate and support uroliths, and can become the core of uroliths, especially urease-...
