Abstract

The invention provides a medical tissue regeneration-promoting hydrogel dressing and a preparation method thereof. The preparation method comprises the steps of (1) taking egg white hydrolysate and animal mucus hydrolysate; (2) preparing extracts of root of flos ixorae chinensis and pelargonium odoyatissimum; (3) dissolving polyvinyl alcohol and polyvinyl pyrrolidone into solvent deionized water, and evenly stirring to obtain a water-soluble polymer solution; dispersing starch and sodium carboxymethyl cellulose into water to prepare starch dispersion liquid; (4) sequentially adding glycerol, ethylenediamine tetraacetic acid disodium, the egg white hydrolysate, the animal mucus hydrolysate, the extract of root of the flos ixorae chinensis and the extract of the pelargonium odoyatissimum; (5) adding epoxy chloropropane, stirring to form a mixed solution, pouring the mixed solution into a mould, and standing to obtain the medical tissue regeneration-promoting hydrogel dressing. When in use, the medical tissue regeneration-promoting hydrogel dressing is free from irritation to the skin, and has a very high wound healing rate.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a medical muscle-promoting hydrogel dressing and a preparation method thereof. Background technique [0002] The healing of scald wound is one of the most important and basic problems faced by the medical field in the treatment of scald, and it is also the focus of current research. Burns and scalds are problems that the medical community is generally concerned about and committed to solving. Although remarkable progress has been made, there is still no ideal solution for the healing of scald wounds and scar tissue repair. Scars will bring great inconvenience to patients. Hypertrophic scars caused by burns can cause local itching, pain, and even dysfunction, which seriously troubles patients. Therefore, new dressings with anti-pollution, anti-secondary trauma, comprehensive protection for wounds and functions of promoting wound healing have become the focus of research and devel...
