Abstract

The invention relates to the technical field of wound surface covering, in particular to a medical composite antibacterial wound surface covering product which is reasonable in structure, convenient,safe and reliable to use, capable of promoting wound healing and low in price, and has a broad-spectrum long-acting antibacterial effect. The medical composite antibacterial wound surface covering product comprises a medical proof fabric layer, a water absorption layer, an antibacterial functional layer and a release paper layer, wherein the water absorption layer and the antibacterial functionallayer are bonded and fixed through a medical-grade hot melt adhesive; the water absorption layer is fixed on the upper surface of the medical proof fabric layer through a non-setting adhesive layer; the area of the water absorption layer is smaller than the area of the medical proof fabric layer; the edge area of the release paper layer is bonded and fixed with the edge area of the medical proof fabric layer; and the central area of the release paper layer is in contact with the surface of the antibacterial functional layer.

Description

technical field [0001] The invention relates to the technical field of wound dressing, in particular to a medical composite antibacterial wound dressing product. Background technique [0002] As we all know, after the wound surface is generated, it is usually disinfected, and then a suitable covering product is selected to fully cover the wound surface, and then fixed with medical tape. The function of the coated product is mainly to protect the wound surface, absorb wound tissue fluid and stop bleeding, thereby promoting wound healing. However, traditional coating products do not contain effective antibacterial ingredients, and cannot eliminate complications such as secondary infection of wounds caused by bacteria, and there are still deficiencies in the treatment of patients with large wounds such as large area burns. At the same time, although traditional coated products can absorb wound tissue fluid and blood, which is beneficial to wound healing, there are no ingredien...
