CARBOXYMETHYL CELLULOSE FOAM FOR HEMOSTASIS AND WOUND TREATMENT, AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a highly liquid absorbent and hardly water-soluble carboxymethyl cellulose (CMC) foam, which absorbs body fluid or water, expands in volume when absorbing liquid, does not gelate, and maintains shape. The hardly water-soluble CMC foam prepared according to the preparation method of the present invention has remarkably superior liquid absorbency, shows large volume expansibility when absorbing liquid, does not gelate, and maintains shape. Therefore, a remarkably improved ability is shown when used as a hemostatic agent and a wound dressing. In addition, when the CMC form is treated with a CMC powder dispersing liquid, the surface characteristics change, thereby preventing agglutination with the skin and improving pressure liquid absorbency. Thus, it is possible to control the liquid absorbency thereof to meet the desired purpose.
