Antimicrobial dressing

Abstract

The present invention relates to an antimicrobial dressing, the antimicrobial dressing comprising: a first cover member which has a plurality of pores formed thereon and makes contact with a wound; an antimicrobial membrane which is laminated to the first cover member, has a plurality of pores formed thereon, and is made by the accumulation of nanofibers containing synthetic polymers, water-soluble polymers that dissolve in an exudate secreting from the wound, and antimicrobial substances released by the dissolution of the water-soluble polymers; and a second cover member which is laminated to the antimicrobial membrane, has a plurality of pores formed thereon, and is exposed to outside air.

Description

technical field [0001] The present invention relates to dressings, and in more detail, to an antibacterial dressing for wound healing that reduces the amount of antibacterial substances in contact with wounds and relieves pain by utilizing water-soluble polymers dissolved in exudate to gradually release antibacterial substances , thus maximizing the antimicrobial properties on the wound surface. Background technique [0002] Usually, when a wound occurs, after disinfecting the wound, the dressing for wound healing is used to sufficiently cover the surface of the wound according to the amount of exudate generated in the wound, and then fixed with medical adhesive tape. [0003] Dressings for wound healing can protect the wound, absorb exudate, promote hemostasis, support the wound, and improve the healing speed by covering the wound surface of the skin defects caused by burns or trauma, decubitus and trauma. [0004] Recently, research on dressings for providing an optimal h...

[0005] Korean Laid-Open Patent Publication No. 2010-0021108 discloses the following antibacterial dressing laminate, which is characterized in that it includes: a nanofiber member containing silver nanoparticles; an exudate absorbing member laminated on the upper part of the nanofiber member; and The cover member is formed of a semi-permeable membrane and laminated on the upper part of the exudate absorbing member, and the nanofiber member containing the above-mentioned silver nanoparticles is formed by spinning a solution containing a fiber-forming polymer and a silver (Ag) metal salt. Electrospinning to form nanofibers in the form of a grid with a fiber diameter of less than 1 μm, so that dressings with antibacterial properties can be realized, but it has the following disadvantages: the silver nanoparticles limit the nanofibers fixed to the nanofiber parts, thus containing silver nanofibers. The nanofiber part of the particle exhibits antibacterial effect only at the position where the laminate is stacked, and the antibacterial property on the wound surface is negligible
