Method for preparing calcium chitosan and itsuse for wound hemostasis

Abstract

This invention relates to a preparation method for calcium chitin characterizing in mixing the chitin with powder of CaCl2, calcium acetate, calcium gluconate, calcium lactate, calcium maltate or citrate calcium malate to be reacted, filtered, cleaned, dewatered, dried, crushed and virus eliminated to get the calcium chitin, which is a new type of hemostatic by acting on the red blood cells in the blood, suppressing soluble fiber protein and activating thrombin so as to arrest bleeding.

Description

technical field

[0001] The invention relates to a preparation method of chitosan calcium, which is used for wound or operation hemostasis. Background technique

[0002] Chitosan is a natural polymer polycation polysaccharide, which has good biocompatibility, no immunogenicity, no toxic side effects, and has hemostatic, antibacterial, anti-infection effects, and can promote wound healing. Good properties of sugar for use as a hemostatic dressing or hemostat. It has been reported that chitosan is used as one of the raw materials to prepare wound hemostatic materials, mainly by compounding chitosan or chitosan derivatives with other materials to make hemostatic sponge or hemostatic film. The preparation process in the reports of these related chitosan hemostatic materials is complicated. Contents of the invention

[0003] The purpose of this invention is to provide a preparation method of hemostatic agent chitosan calcium and the application of the hemostatic agent in traum...
