Title:
PHOTO-CROSS-LINKING COPOLYMERIZED HYALURONIC ACID SPONGE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/108264
Kind Code:
A1
Abstract:
The present invention relates to a photo-cross-linking copolymerized hyaluronic acid sponge and a preparation method therefor, and, more specifically, to a photo-cross-linking copolymerized hyaluronic acid sponge and a preparation method therefor, the sponge not being sticky and not dripping, having flexibility to be usable in various parts of the body, having excellent water binding force to help tissue regeneration, having very excellent biocompatibility so as to be absorbable into the skin when attached to the body for a long time, so that the trouble of having to be removed can be decreased, and comprising, through a photo-cross-linking reaction, polymers having various lengths so as to be applicable in various forms of medical antihemorrhagic agents, wound-coating agents, adhesive barriers and the like.
