Embodiment 1
[0024] 1. Dissolve 3 g of PVA-SbQ in 30 mL of deionized water, add 2.0 mg of flavonoid glycosides into the PVA-SbQ solution to obtain a PVA-SbQ / flavonoid glycoside solution.
[0025] 2. Immerse the separated and purified bacterial cellulose film produced by Acetobacter xylinum in PVA-SbQ solution for 24 hours, and irradiate with 400W ultraviolet light for 1 hour to obtain the vacciola flavone glycoside / bacterial cellulose composite film. After drying at room temperature, a wet antibacterial hydrogel dressing capable of treating diabetic foot ulcers is obtained. The dressing is a composite hydrogel film composed of bacterial cellulose hydrogel and PVA-SbQ solution containing wangbuliuxing flavonoid glycoside.
Embodiment 2
[0027] 1. Dissolve 3 g of PVA-SbQ in 30 mL of deionized water, add 1.8 mg of flavonoid glycosides into the PVA-SbQ solution to obtain a PVA-SbQ / flavonoid glycoside solution.
[0028]2. Immerse the separated and purified bacterial cellulose film produced by Acetobacter xylinum in PVA-SbQ solution for 24 hours, and irradiate with 400W ultraviolet light for 1 hour to obtain the vacciola flavone glycoside / bacterial cellulose composite film. After drying at room temperature, a wet antibacterial hydrogel dressing capable of treating diabetic foot ulcers is obtained. The dressing is a composite hydrogel film composed of bacterial cellulose hydrogel and PVA-SbQ solution containing wangbuliuxing flavonoid glycoside.
Embodiment 3
[0030] 1. Dissolve 3 g of PVA-SbQ in 30 mL of deionized water, add 1.6 mg of flavonoid glycosides into the PVA-SbQ solution to obtain a PVA-SbQ / flavonoid glycoside solution.
[0031] 2. Immerse the separated and purified bacterial cellulose film produced by Acetobacter xylinum in the PVA-SbQ solution for 24 hours, and irradiate with 400W ultraviolet light for 1 hour to obtain the flavonoid glycoside / bacterial cellulose composite film .
