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, the application first uses chitosan and polyoxyethylene as raw materials to prepare a chitosan film by electrospinning to obtain The chitosan film is used as the dressing base film. Because chitosan has the characteristics of non-toxicity, broad-spectrum antibacterial property, hemostasis, scar reduction and good biocompatibility, chitosan is selected as the main raw material, and Introduce plant extracts. The plant extracts of this application are ginseng extract + Ophiopogon japonicus extract, ginseng extract + chrysanthemum extract and ginseng extract + Artemisia annua extract. You can choose to mix and match at will. The invention has reasonable process design and simple operation, and the prepared combined dressing not only has excellent antibacterial performance, but also is non-toxic to human body, has good biocompatibility, and can promote skin surface wound healing when used, and has high practicability.

Description

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