Problems solved by technology

[0003] Because chitosan has excellent non-toxic, antibacterial, and biocompatibility, chitosan film is generally used as dressing base film, and polydopamine layer is coated on the surface of chitosan film to increase the load of subsequent particles. effect, but the existence of polydopamine layer will reduce the air permeability of chitosan film, the air permeability is poor in actual use, which will affect wound healing

Abstract

The invention discloses a plant extract combined dressing based on ginseng extract and a preparation method thereof. During preparation, chitosan and polyoxyethylene serve as raw materials, a chitosan film is prepared through electrostatic spinning, the chitosan film serves as a dressing base film, chitosan has the characteristics of no toxicity, broad-spectrum antibacterial property, hemostasis, scar reduction, good biocompatibility and the like, so that chitosan is selected as a main raw material, and plant extracts are introduced; the plant extract is compounded by three combination modes of the ginseng extract and the radix ophiopogonis extract, the ginseng extract and the chrysanthemum extract and the ginseng extract and the artemisia apiacea extract, and matching and selection can be randomly carried out in actual operation. The process is reasonable in design and simple to operate, and the prepared combined dressing not only has excellent antibacterial performance, but also is non-toxic to a human body and good in biocompatibility, can promote healing of wounds on the skin surface during use, and has relatively high practicability.

Description

technical field [0001] The invention relates to the technical field of dressings, in particular to a ginseng extract-based plant extract combined dressing and a preparation method thereof. Background technique [0002] Medical dressing is a medical material that is widely used nowadays. It is a medical material that can target the actual situation of the wound and provide special functions for wound healing. As a wound covering, medical dressings can replace damaged skin to act as a temporary barrier during the wound healing process, which can avoid or control wound infection and provide a good healing environment for the wound. [0003] Because chitosan has excellent non-toxic, antibacterial, and biocompatibility, chitosan film is generally used as dressing base film, and polydopamine layer is coated on the surface of chitosan film to increase the load of subsequent particles. However, the existence of the polydopamine layer will reduce the air permeability of the chitosan...
