The present invention relates to a hemostatic injection needle coated with a chitosan in which a catechol group and an oxidized catechol group are introduced and cross-linked. The hemostatic injection needle according to the present invention can suppress bleeding during and after injection, and thus can be effectively used for injection not only into coagulopathy patients, including diabetic patients, patients under anticancer treatment, and haemophilia patients, who have a low hemostatic ability, but also into patients showing blood rejection responses, and children.
