Application of composite antibacterial nanoparticle non-woven fabric in sterilization of hospital infection

Abstract

The use of disinfection materials and instruments is an important part of surgical operation. Hospital environment and surgical equipment need comprehensive sterilization treatment. This process is the key to the success of the operation, and it is also one of the first ways to control the hospital to avoid infection during the operation. The selection of scientific and reasonable sterilization methods for infection will directly affect the safety of medical treatment. In order to improve the antibacterial properties of medical non-woven fabrics, this paper combines two antibacterial methods of sterilization and antibacterial adhesion, and uses the principle of nanotechnology to design that the non-woven fabrics have good blood compatibility in the sterilization process. Then, a new composite antibacterial nanoparticle antibacterial solution is prepared from the synthesized nano‑silver solution, and the antibacterial solution is attached to the non-woven fabric, so that the nano‑silver particles with antibacterial effect are fixed on the surface of the fabric, and its antibacterial effect is measured through the antibacterial test, and excellent hospital infection sterilization technology is prepared and applied to the non-woven fabric products. The fusion experiment of platelets and red blood cells shows that the prepared surface technology combined with antibacterial adhesion and sterilization can effectively fuse with platelets and red blood cells, and can also effectively prevent the adhesion of platelets and red blood cells, and shows good blood compatibility, which is applicable to the sterilization process of hospital infection.
