Problems solved by technology

[0003] The primary problem of medical bandages is the high risk of infection. The moist environment provided by the bandages is also suitable for the growth and reproduction of bacteria. Usually, people wrap the bandages with silver particles to kill bacteria. However, the amount of silver particles used is too high. Assembly limits or reduces efficacy and adversely affects mammalian cells, therefore,

Abstract

The invention relates to the technical field of research and development of medical bandages and discloses a non-adherent antibacterial medical bandage. A non-adherent material and an antibacterial agent are added to absorbent cotton gauze, the prepared non-adherent material has very high adsorption performance on the bandage and cannot fall off, and the used antibacterial agent is prepared from natural components, has good antibacterial and bacteriostasis effects and cannot cause infection after healing. The bondage is endowed with the non-adherent property, can be easily removed from wound surfaces during usage and can effectively inhibit adhesion of hemoglobin and blood clots, thus, the prepared non-adherent antibacterial medical bandage has unique advantages in non-adhesion, biocompatibility, antibacterial property, mechanical strength, convenience in use and the like and has broad application prospects in the biomedical field.

Description

technical field [0001] The invention belongs to the technical field of research and development of medical bandages, in particular to an anti-adhesive antibacterial medical bandage. Background technique [0002] Medical bandages are gauze bandages that bind wounds or affected areas. They are common medical supplies and come in many different varieties. The simple one is the single shed belt, made of gauze or cotton, and applied to the limbs, tail, head, and abdomen. Complex bandages are bandages of various shapes made according to the position and shape. The material is double-layer cotton cloth, and cotton of different thicknesses can be sandwiched between them. There are cloth strips around it for knotting and fixing. Chest bandages, abdominal bandages, nail bandages, etc. Special bandages are mostly used for fixation on limbs and joints. [0003] The primary problem of medical bandages is the high risk of infection. The moist environment provided by bandages is also su...
