23 Jul Method for preparing medical dressing of polysaccharide cavernous body
Abstract
The invention relates to the preparation technique of tissue engineering scaffold materials and provides a crosslinking method for preparing medical dressing of a polysaccharide cavernous body. Chitosan and sodium alga acid serve as the base material, and by means of crosslinking of a couple reaction and the freezing drying technique, water absorption capability of the medical dressing of the polysaccharide cavernous body is improved, and effective protection on skin wound is achieved. When used, the medical dressing of the polysaccharide cavernous body is directly compressed on the wound surface, has excellent adsorption effect, and is particularly suitable for skin diseases of burning, pus, wound drainage, ulcer and the like. The method for preparing medical dressing of the polysaccharide cavernous body is simple in process, low in cost, low in crosslinking temperature, fast in curing, and suitable for large-scale industrial production. By means of the method, water adsorption capability of the dressing is obviously improved, residue of toxic chemical cross-linked agents is avoided simultaneously, chemical stimulation on the skin caused by materials is reduced, and biocompatibility and safety of the dressing are improved.
