Therefore, the proper dressing material is used for protecting the wound and providing a proper environment for wound healing, and plays an important role on the skin wound surface of a patient;
compared with the hydrophilic dressing material, the self-pumping dressing material can manage wound exudate and prevent wound rewetting, and can promote cell proliferation and differentiation in the wound repair process due to the porous structure, the high specific surface area and the bionic structure similar to human skin, thereby being an ideal medical material for promoting wound healing.
At present, widely used hydrophilic wet dressing has a certain wound exudate absorption function, but when wound exudate is excessive or is not removed in time, the wet dressing is easy to become a pollution source, so that wound tissue is hydrated and infected, and recovery of a patient is affected.
For this reason, a person skilled in the art proposes an anti-infective material based on electrospun nanofibers to solve the problems posed by the background art.
