Title:
ADHESION PREVENTING FILM HAVING EXCELLENT BONDING STRENGTH
Document Type and Number:
WIPO Patent Application WO/2019/156463
Kind Code:
A1
Abstract:
The present invention relates to an adhesion preventing film and, more specifically, to an adhesion preventing film, which is prepared by the steps of: mixing an adhesion preventing composition comprising distilled water, polyethylene oxide (PEO) and an alginate; casting the mixed composition, and then freeze-drying the same, so as to manufacture a sponge-type film; compressing the sponge-type film; and cross-linking the compressed film by emitting, thereat, one or more light sources selected from radioactive rays, electron beams, gamma rays and ultraviolet rays, and is capable of improving bonding strength onto a mucous membrane.
The present invention provides an adhesion preventing film which is prepared by casting an adhesion prevention composition and then freeze-drying the same, so as to manufacture a sponge-type film, compressing the sponge-type film, and then cross-linking the compressed film, and which has excellent mechanical strength, flexibility, bonding strength, cytotoxicity, biodegradability, biocompatibility, adhesion preventing characteristics and the like.
