Degradable antibacterial hemostatic fiber pad and preparation method thereof

Abstract

The invention discloses a degradable antibacterial hemostatic fiber pad and a preparation method thereof. The degradable antibacterial hemostatic fiber pad comprises the following components in parts by weight: polyurethane, D-polylactic acid, L-glycine, silk protein, dextran, hydroxyethyl cellulose, polyvinylpyrrolidone, citric acid, an antibacterial agent, sodium hydroxide, trimethylolpropane, sodium trimetaphosphate, 18 to 30 parts of ethanol, and double distilled water. The hemostatic fiber pad provided by the invention has a bleeding amount of less than 0.13g and an antibacterial rate of more than 99.1%, showing a good hemostatic effect. In addition, the hemostatic fiber pad has good biocompatibility and short wound healing time, is easily torn off without damaging tissues, does not bring secondary damage, and has good application prospects.

Description

technical field [0001] The invention belongs to the field of hemostatic materials, and in particular relates to a degradable antibacterial and hemostatic fiber pad and a preparation method thereof. Background technique [0002] In daily life, whether it is emergency treatment of various sudden accidents or trauma hemostasis in the process of treatment, it is very important for patients to effectively and quickly stop bleeding locally; The death rate from the cause of hemorrhage remains high. Therefore, it is of great significance to develop an effective rapid hemostatic material to accelerate the speed of coagulation, and to reduce the mortality rate caused by excessive blood loss. [0003] In the prior art, the traditional hemostatic fiber material usually uses hemostatic gauze, which is mainly made of cotton, linen, etc., which has poor antibacterial and antibacterial ability, gauze fibers are easy to cause foreign body rejection and affect wound healing, and are easy to ...

Problems solved by technology

[0003] In the prior art, the traditional hemostatic fiber material usually uses hemostatic gauze, which is mainly made of cotton, linen, etc., which has poor antibacterial and antibacterial ability, gauze fibers are easy to cause foreign body rejection and affect wound healing, and are easy to contact with wound tissue during use. Adhesion, causing secondary damage and other problems, and the waste treatment process after use is complicated and easy to pollute the environment
