Abstract

The invention discloses a medical collagen antibacterial film. The medical collagen antibacterial film is prepared from 68-82 parts by mass of chitosan, 78-92 parts by mass of collagen, 8-15 parts by mass of sodium alginate, 4-7 parts by mass of Lysimachia lobelioides Wall., 6-10 parts by mass of Grewia lantsangensis Hu, 3-6 parts by mass of gentianopsis barbata, 5-8 parts by mass of lotus leaf, 7-10 parts by mass of all-grass of small coleus, 3-5 parts by mass of trichosanthes root, 4-8 parts by mass of herba lycopi, 6-10 parts by mass of peruvian groundcherry herb, 3-7 parts by mass of leaf of Chinese holly, 4-9 parts by mass of pipewort, a proper amount of glycerin, a proper amount of dicumyl peroxide and a proper amount of borneol. The Chinese herbal medicine antibacterial components with reasonable compatibility are added into the film forming material so that the medical collagen antibacterial film has effects of killing bacteria, fungi and viruses, has good antibiosis effects and can effectively prevent wound infection.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a medical collagen antibacterial film and a preparation method thereof. Background technique [0002] Since the advent of penicillin in 1929, antibacterial drugs have been used in clinical medicine for the treatment and prevention of infections. However, as the long-term use of penicillin leads to the emergence of drug-resistant strains, countries around the world have developed generations of antibacterial drugs to deal with the serious problem of drug resistance, which affects the development of clinical medicine. But this not only failed to solve the problem of drug resistance, but also led to the growth of bacterial resistance. Nowadays, there are more and more antibacterial drugs and newer ones, and the emergence of drug-resistant bacteria caused by long-term use of antibacterial drugs. At the same time, there are also problems such as toxic reactions, allergic reactions, a...
