Preparation process of dissolvable hemostatic gauze

Abstract

The invention discloses a preparation process of a dissolvable hemostatic gauze, which takes absorbent cotton gauze as the main raw material, and processes the raw material by sodium hydroxide solution, chloroacetic acid solution, ethanol solution and the like to prepare the dissolvable hemostatic gauze which has good dissolubility, can be absorbed by human body without toxic and side effect, does not pollute environment and has good and rapid hemostasis effect. The dissolvable hemostatic gauze has good hemostasis effect on traumatism, cortex bleeding, bleeding caused by muscle strain and postoperative bleeding of brain and ambition surgery, particularly has good hemostasis effect on the bleeding caused by less blood cells and cruor dysfunction of a patient.

Description

technical field [0001] The invention relates to a medical dressing, in particular to a preparation process for dissolving hemostatic gauze. Background technique [0002] Gauze is widely used in the field of medical and health care, and is mainly used for stuffing and bandaging wounds to stop bleeding in a short period of time. At present, there are two main research directions for hemostatic gauze: one is to focus on the hemostatic effect and the speed of its function, represented by developed countries such as the United States and Germany, which mainly use the drug components with hemostatic function to treat the gauze, and realize it with the help of drugs. The advantage of hemostasis is that the hemostatic effect is good and the effect is rapid, but the disadvantage is that the drug has unavoidable side effects on the human body; the second is to focus on the research on the solubility of gauze to prevent wound adhesion and secondary pollution after use. Some degradable...

At present, there are two main research directions for hemostatic gauze: one is to focus on the hemostatic effect and the speed of its function, represented by developed countries such as the United States and Germany, which mainly use the drug components with hemostatic function to treat the gauze, and realize it with the help of drugs. The advantage of hemostasis is that the hemostatic effect is good and the effect is rapid, but the disadvantage is that the drug has unavoidable side effects on the human body; the second is to focus on the research on the solubility of gauze to prevent wound adhesion and secondary pollution after use. Some degradable gauzes have come out, and their hemostatic mechanism is mainly to stop bleeding by compression. In fact, the hemostatic function of platelets is still used. Therefore, for bleeding patients with less platelets and coagulation dysfunction, the hemostatic effect is not ideal.
