The invention discloses a preparation method of medical gauze for rapid hemostasis. The preparation method is as follows: 1) pretreatment of degreasing gauze, 2) improvement of conventional hemostatic agent and 3) impregnation treatment of degreasing gauze; Some conventional hemostatic materials are improved to form a powder microsphere with a hemostatic material in the core, and then attached to the treated degreased gauze to form a new type of composite hemostatic gauze, which is stable and safe. Environmentally friendly, the hemostatic effect is remarkable. The hemostatic material attached to the gauze will be released according to the amount of blood at the wound to promote blood coagulation, and will form a certain squeezing effect on the wound during use, which can accelerate the coagulation speed of blood at the wound , and reduce blood loss, so as to achieve rapid hemostasis. |
