Antibacterial and hemostatic bifunctional material and preparation method thereof

Abstract

The invention discloses an antibacterial and hemostatic bifunctional material and a preparation method thereof. Through oxidation grafting of polyethyleneimine, various forms of powder, film, gel, non-woven fabric or textile are obtained according to different cellulose substrates; the material provided by the invention has both antibacterial and hemostatic properties, and the antibacterial property is durable and stable, and can quickly stop bleeding and diminish inflammation without any medicine; and the preparation method of antibacterial cloth and an antibacterial and hemostatic dressing has the advantages of low reaction temperature, simple condition, low energy consumption, and easy large-scale industrial production.

Description

technical field [0001] The invention relates to an antibacterial and hemostatic dual-function material and a preparation method thereof, belonging to the field of medical dressings. Background technique [0002] Cotton, gauze and non-woven fabrics have been widely used in the medical field as commonly used wound dressings. However, they have the disadvantages of poor liquid absorption, easy adhesion and no antibacterial hemostasis, which makes it difficult to remove during use. , easy to cause secondary trauma hazards. In addition, ineffective hemostasis is more likely to cause serious consequences such as wound infection, hypothermia, coagulation dysfunction, and multiple severe organ failure. [0003] At present, some existing antibacterial gauzes generally achieve antibacterial purposes by adding antibacterial agents such as antibacterial drugs (such as patent CN101780291A) or nano silver (such as patent CN1291667A), but there are problems of antibacterial drug tolerance...

Problems solved by technology

[0002] Cotton, gauze and non-woven fabrics have been widely used in the medical field as commonly used wound dressings. However, they have the disadvantages of poor liquid absorption, easy adhesion and no antibacterial hemostasis, which makes it difficult to remove during use. , easy to cause secondary trauma

In addition, ineffective hemostasis is more likely to cause serious consequences such as wound infection, hypothermia, coagulation dysfunction, and multiple severe organ failure.

[0003] At present, some existing antibacterial gauzes generally achieve antibacterial purposes by adding antibacterial agents such as antibacterial drugs (such as patent CN101780291A) or nano silver (such as patent CN1291667A), but there are problems of antibacterial drug tolerance and antibacterial properties such as nano silver. The enrichment of agents is still a difficult problem
