Method for preparing astringent sponge of soluble cellulose

Abstract

A staltic soluble cellulose sponge is proportionally prepared from carboxymethyl cellulose sodium and chitosan through dissolving carboxymethyl cellulose sodium in distilled water, dissolving chitosan in diluted acetic acid, mixing, adding polyethanediol 400, cane sugar and glycerin, stirring, laying aside while defoaming, filming, and vacuum freeze-drying.

Description

technical field

[0001] The invention relates to a preparation method of a spongy material, in particular to a preparation method of a soluble cellulose hemostatic sponge. Background technique

[0002] The rapid development of modern surgical medical technology has made great contributions to saving lives and healing the wounded. There are three major obstacles to the development of surgical operations, namely pain, wound infection, and bleeding. The problem of pain has been basically solved, and the continuous replacement of antibiotics has also basically solved the problem of wound infection. Bleeding has just become the biggest obstacle hindering the development of surgical operations. In surgical operations, whether the bleeding can be effectively stopped sometimes becomes the key to determine the success of the operation. At present, surgeons generally use ligation, suture ligation and electrocoagulation as methods for hemostasis and wound healing, but this method is n...
