Safe and stable polymer mixed dressing

The safe and stable polymer mixed dressing is prepared from the following raw materials in parts by weight: 12 to 16 parts of chitosan, 5 to 10 parts of sodium alginate, 6 to 9 parts of silver nanoparticles, 5 to 8 parts of radix notoginseng powder, 6 to 10 parts of pearl powder, 6 to 10 parts of starch acetate, 9 to 13 parts of polyvinyl alcohol, 4 to 8 parts of rhizoma drynariae, 5 to 9 parts of radix astragali seu hedysari, 6 to 11 parts of herba thuniae, 6 to 9 parts of herba asari and 12 to 15 parts of water. According to the safe and stable polymer mixed dressing, degradation of a dermal matrix is delayed through arranged chitosan, arranged sodium alginate is used for stopping bleeding, resisting inflammation and preventing growth of granulation tissue, arranged nano-silver particles are used for strongly inhibiting bacteria and preventing infection, and after the chitosan, the sodium alginate and the silver nano-particles are combined, it is found that the medicine generates a positive synergistic effe
