Abstract

The invention relates to a natural high-polymer material adhesive bandage which comprises a sodium alginate film, wherein a polyester / adhesive / paper material is covered on the surface layer. The bottom layer composite film is prepared from sodium alginate, and thus, has the obvious effects of arresting bleeding, resisting infection, promoting wound healing and the like. The sodium alginate has favorable biocompatibility, and avoids the wound adhesion. The polyester / adhesive / paper material layer can completely obstruct liquid infiltration as a lining, and performs the function of protecting the wound. The composite film medical dressing is suitable for traumatic hemorrhage, various surgical incision sterile protective films, indwelling needle fixing films, sterile application and many other wound surface protective films.

Description

technical field [0001] The project belongs to the field of science and technology of biology, medicine and medical equipment. Background technique [0002] With the in-depth research on wound healing, people realize that the purpose of using dressings is far more than just to cover the wound surface. Can promote wound healing. [0003] Research in recent years has shown that wounds heal faster in a moist environment. Under the guidance of the theory of "moist wound healing", and with the progress of material science and industrial science, new changes have taken place in wound dressings. There are more than 10 types of functional dressings made from alginic acid. The representative alginate fiber dressing has the characteristics of high moisture absorption, easy removal, high oxygen permeability, and good compatibility with the human body, and is very suitable as a medical surgical material. [0004] As the national policy strictly controls the use of antibiotics, postop...
