| titleOfInvention | A kind of chitosan hydrogel and preparation method and its application in gastric filler |
| abstract | The invention discloses a chitosan hydrogel, a preparation method and its application in gastric filler, and relates to the field of medical assistance. Chitosan hydrogel includes chitosan and polyanionic natural polysaccharide, and its preparation steps are: dissolving chitosan in solvent A to prepare chitosan acetic acid solution; dissolving polyanionic natural polysaccharide in solvent B to prepare A polyanionic natural polysaccharide solution is obtained; silicone oil is added to the polyanionic natural polysaccharide solution, and after stirring, a chitosan acetic acid solution is added to form a solution with gel microspheres, and the pH value is stirred and adjusted; the gel microspheres are centrifuged The method is separated from the solution, the gel microspheres are immersed in pure water, and dried to obtain a chitosan hydrogel, which is used in a gastric filler. The chitosan hydrogel of the present application has high swelling ratio and high pH sensitivity as a gastric filler, and at the same time can actively adjust body weight, and has simple preparation steps, low cost and safe ingredients. |
