The present invention relates to wound dressings, and more particularly to antibacterial wound dressings.

The use of wound dressings is a common wound treatment method. The wound dressing generally has an anti-inflammatory pad that can prevent infection by contacting the wound site and absorbing exudate from the wound site, and an adhesive sheet on which the pad is placed. By attaching the adhesive sheet to the human body and directly contacting the wound site with the pad for a certain period of time, there is an effect of promoting the healing of the wound.

Hereinafter, each embodiment of the wound dressing of the present invention will be described in detail with reference to the drawings.

The wound dressing of the present invention comprises a surface fabric layer 1 having an outer surface facing the outside, and a wound dressing disposed on the inner surface of the surface fabric layer 1, as in each of the following embodiments shown in Figures 1-2. and a pad layer 2 for contacting the site, and at least one of the surface fabric layer 1 and the pad layer 2 is uniformly coated with an antibacterial material 90 composed of a conductive polymer material having an antibacterial effect. It can also be configured to be interspersed.

FIG. 1 is a cross-sectional view showing a first embodiment of the wound dressing of the present invention.

In a first embodiment of the wound dressing of the present invention, the antimicrobial material 90 is evenly distributed only throughout the surface fabric layer 1, as shown in FIG.

As a constituent material of the surface cloth layer 1, natural fibers or artificial fibers can be used, and the form of the surface cloth layer 1 is not particularly limited as long as the pad layer 2 can be placed and positioned, such as woven fabric or non-woven fabric. can be configured in the form of

The conductive polymer material used for the antimicrobial material 90 is a mixture of polythiophene-based derivatives and polystyrene sulfonic acid.

The conductive polymer material is positively charged due to effects such as the chemical attractive force caused by the doping of polystyrene sulfonic acid to the polythiophene-based conjugated polymer. Since bacteria have a negative charge on the surface, the conductive polymer material neutralizes the negative charge on the surface of the bacteria, causing the bacteria to atrophy and die. Has a sterilizing effect.

In addition, by testing the conductive polymer material against multiple types of bacteria in the SGS standard test, methicillin-resistant Staphylococcus aureus (SGS standard test report number: PUG20C01550), Pseudomonas aeruginosa (SGS standard test report number: PUG20C01551 ) and E. coli (SGS standard test report number: PUG20C01552), the sterilization rate is all 99.9% or more over 24 hours, and Candida albicans (SGS standard test report number: PUG20C01553) Over time, the sterilization rate was greater than or equal to 65.4%, so the SGS standard test demonstrated the antimicrobial efficacy as the conductive polymer material was able to achieve a high sterilization rate in the test.

In addition, in this embodiment, the pad layer 2 has adhesiveness, and when the pad layer 2 adheres to the human body due to its own adhesiveness, the antibacterial material 90 on the surface cloth layer 1 is the antibacterial property of the conductive polymer material. In addition to the original function of the pad layer 2, the possibility of bacterial infection can be further reduced due to the antibacterial effect.

FIG. 2 is a cross-sectional view showing a second embodiment of the wound dressing of the present invention.

A second embodiment of the wound dressing of the present invention is similar to the first embodiment, and the differences from the first embodiment are described below.

In this embodiment, only the entire padding layer 2 is uniformly dispersed with antimicrobial material 90, as shown in FIG.

That is, when the pad layer 2 of this embodiment adheres to the human body, since there is the antibacterial material 90 that comes into direct contact with the human body, the antibacterial effect can be exhibited and the possibility of infection can be further reduced.

In addition, the wound dressing of the present invention is interposed between the pad layer 2 and the surface fabric layer 1 as in the following embodiments shown in FIGS. At least one of the surface fabric layer 1, the pad layer 2 and the adhesive layer 3 is uniformly coated with an antibacterial material 90 made of a conductive polymer material having an antibacterial effect.
