Technical Field

[0001] The utility model relates to the technical field of wound dressings, in particular to a bacterial cellulose biological dressing. Background Art

[0002] In the preparation process of bacterial cellulose dressings, highly purified cellulose matrices are produced by culturing and fermenting specific bacteria. According to different usage requirements, these cellulose matrices can be used to make various forms of dressings. For example, some dressings are suitable for application on injection sites, which can effectively fix the needle, prevent infection and leakage; some dressings are suitable for application on wounds, which can absorb the exudate from the wound and promote wound healing; some dressings are impregnated with various biological solutions to achieve the required specific functions.

[0003] For the type of dressing impregnated with various biological solutions, the structure consists of a bacterial cellulose membrane impregnated with a biological solution and two protective films covering the upper and lower surfaces of the bacterial cellulose membrane. However, after the protective film is covered, it is fixed by the adsorption force of the biological solution. However, the adsorption capacities of different biological solutions are different. Therefore, for some biological solutions with poor adsorption capacity, the fixing effect on the protective film is not ideal, resulting in the position of the protective film being prone to loosening and slipping, thus affecting the protection effect on the bacterial cellulose membrane.
