The invention discloses a moist antibacterial hydrogel dressing for curing
diabetic foot ulcer, and relates to the technical field of
medical instruments and preparation thereof. The dressing is prepared by the following steps: dissolving ionic compounds in
sodium alga
acid water solution, and obtaining nano-silver
sodium alga acid solution through adding
reducing agent; adopting the impregnation method, placing the nano-silver
sodium alga acid solution in a
bacterial cellulose membrane, so as to obtain
bacterial cellulose / nano-silver sodium alga acid
composite membrane through
freeze drying; and immersing the
composite membrane in
calcium chloride water solution, and obtaining the moist antibacterial hydrogel dressing for curing
diabetic foot ulcer. The dressing is a composite
hydrogel membrane including
bacterial cellulose hydrogel and nano-silver contained
calcium alginatehydrogel. The preparation is convenient to operate and low in cost, and the moist antibacterial hydrogel dressing prepared for curing
diabetic foot ulcer has the performances of sterilizing, preserving
moisture, absorbing wound percolate, quickening
wound healing and the like, and is applied to curing wound traumas of
diabetic foot ulcer, venous ulcer,
pressure sores and donor site wounds at the lower limbs.
