Embodiment 1

[0020] Prepare 3 kg of dissolved hemostatic gauze as follows:

[0021] (1) 10L of sodium hydroxide solution with a concentration of 15% (percentage by weight) and 20L of ethanol solution with a concentration of 25% (percentage by volume) were added to the reaction tank, and stirred to obtain 30L mixed solution I;

[0022] (2) drop into 3kg absorbent cotton gauze in mixed solution I, stir 90min;

[0023] (3) 11.5L of chloroacetic acid solution with a concentration of 10% (percentage by weight) and 18.5L of ethanol solution with a concentration of 4% (percentage by volume) are configured into 30L mixed solution II;

[0024] (4) Add the mixed solution II evenly dropwise into the reaction tank within 60 minutes with a burette, and continue to stir for 180 minutes, during which attention should be paid to prevent the gauze from being entangled, so as not to affect the uniformity of the gauze;

[0025] (5) Take out a piece of gauze with a size of about 50mm×50mm from the reaction t...

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.
