Kaolin-based hemostatic gauze and preparation method thereof

Abstract

A kaolin-based hemostatic gauze comprises: a medical non-woven fabric as a carrier; and a kaolin-containing composite hemostatic material loaded on the medical non-woven fabric, wherein kaolin serves as a carrier in the kaolin-containing composite hemostatic material, the kaolin is doped with Ce and α-Fe2O3 is loaded on the Kaolin. A method for preparing the kaolin-based hemostatic gauze, includes: S1: preparing the kaolin-containing composite hemostatic material; S2: preparing the kaolin-containing composite hemostatic material into a suspension; S3: impregnating the medical non-woven fabric with the suspension thoroughly stirred, wherein upper and lower sides of the medical non-woven fabric each are impregnated once; and S4: pressing and oven-drying an impregnated medical non-woven fabric to obtain the kaolin-based hemostatic gauze. In the method, the medical non-woven fabric is combined with the powdery hemostatic material Ce-α-Fe2O3/Kaol through impregnation to prepare the medical hemostatic gauze product with excellent hemostatic performance, prominent biocompatibility, high safety, and antibacterial activity.
