Medical absorbable oxycellulose material and preparation method thereof

The invention belongs to the technical field of a biologically medical material, and concretely relates to a medical absorbable oxycellulose material and a preparation method thereof. The material has dual functions of stopping bleeding and restoring wound. The material takes natural cellulose as a raw material, and is oxidized by an oxidation system under certain technology condition, the obtained product is subjected to acid treatment, washing by water and drying to prepare the medical absorbable oxycellulose material. The oxidation system has the advantages of strong selectivity, mild and controllable condition, and environmental protection of preparation technology. The prepared material has the advantages of rapidly stopping bleeding and rapidly being absorbed, has wound restoration function, can promote the healing of wound, and has wide application value on medical science.
