MULTIFUNCTIONAL COMPOUND SKIN OR WOUND DRESSING AS REGENERATIVE SKIN SUBSTITUTE

摘要

Provided is a new bionic skin material with multiple functions and a high efficacy. With a compound microporous fibre net structure, the material imitates a skin barrier function, has anti-fouling properties, hygroscopic properties, moisture retention properties, air permeability, flexibility and adhesiveness, and can effectively absorb wound exudate and residues for rapid painless autolysis and debridement, ensure sufficient drainage by bidirectional regulation, maintain a semi-closed, local physiological wet environment favorable for the reparative metabolism and physiological healing of a wound, inhibit inflammation, reduce exudation, benefit the response inside and outside of cells, promote the migration of fibroblasts and epithelial cells of the body itself and the regeneration of granulation tissue and epithelial cells of the wound, accelerate the physiological healing and recovery of the wound, and reduce recurrences. It has been clinically proved that the dressing material can accelerate the healing of acute skin injuries and chronic ulcer wounds, achieve a high healing quality, avoid or reduce traumatic skin grafting to the greatest extent, reduce the pain of patients and the production of scars, and restore the physiological function and appearance of the body.
