Problems solved by technology

[0003] Hemostatic gauze was invented by people to quickly stop bleeding in patients. Its efficacy does not depend on the normal coagulation matrix in the human body, and it is very effective in controlling bleeding in small blood vessels. Its endogenous hemostatic mechanism can achieve rapid hemostasis. The appearance of hemostatic gauze greatly It improves the hemostatic efficiency and provides guarantee for the subsequent treatment. However, the traditional hemostatic gauze needs to press the wound when it is used, which will not only increase the pain of the injured wound, but also have a general effect; The hemostatic agent is sprayed on the hemostatic gauze to make a composite hemostatic gauze, which accelerates blood coagulation through the exogenous coagulation pathway, thereby further improving the hemostatic efficiency. However, the hemostatic agent is easily affected by the external environment during long-term storage Oxidation and pollution, resulting in decreased hemostatic effect

Abstract

The invention discloses a preparation method of medical gauze for realizing rapid hemostasis, wherein the preparation method comprises the following steps: 1) pretreatment of degreased gauze, 2) improvement treatment of a conventional hemostatic agent, and 3) immersion treatment of degreased gauze. Powder microspheres having an inner core loaded with a hemostatic material are formed by improvementtreatment of the conventional common hemostatic material, and then are attached on the treated degreased gauze to form the novel composite hemostatic gauze. The hemostatic gauze is stable in nature,safe and environmentally friendly, and has remarkable hemostatic effect. The hemostatic material attached to the gauze can be released according to the amount of blood in a wound, promotes blood coagulation, forms a certain squeezing effect on the wound in the use process, can accelerate the blood coagulation speed in the wound, and reduce the amount of blood loss, so as to achieve rapid hemostasis.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to a preparation method of medical gauze for rapid hemostasis. Background technique [0002] Blood is an important carrier for sending oxygen to the body. When the human body loses too much blood due to injury, the organs and cells will malfunction and fail, which will affect life safety. Uncontrolled bleeding has always been the main cause of casualties, and timely and effective hemostasis can save at least 30% of the casualties caused by excessive bleeding. Bleeding is also the main cause of traumatic death such as war wounds, falling injuries, and car accident injuries. Successful hemostasis within an effective time is of great significance to saving lives. All countries in the world attach great importance to the research on post-traumatic hemostasis measures. [0003] Hemostatic gauze was invented by people to quickly stop bleeding in patients. Its efficac...
