Abstract
Provided is a dressing with a nano-zinc oxide composite antibiosis layer. The dressing is provided with a base cloth (1). An adhering layer (2) is arranged on the inner face of the base cloth in a coating mode. A protecting layer (3) is pasted on the middle adhering layer of the base cloth. Release paper (4) is arranged on the protecting layer. The outer edge of the release paper is fixed on a corresponding exposed part on the periphery of the base cloth. The dressing is characterized in that the protecting layer is divided into three layers which are a nano-zinc oxide composite layer (3.1), a spongy fabric layer (3.2) and a non-woven fabric reinforcing layer (3.3) in sequence from the position near the base cloth to the position far from the base cloth, the thickness of the nano-zinc oxide composite layer is 0.5 mm- 1mm, the nano-zinc oxide composite layer is formed by the fact that nano-zinc oxide particles (3.12) are evenly arranged on a polymer base (3.11) in a coating mode, the D90 particle diameter of the nano-zinc oxide particles is 30 nm-50 nm, polylactic acid is used on the polymer base, and the nano-zinc oxide particles are fixed on the polymer base in an adhesive-bonding or heating-fixing mode.
Description
Invention field
The present invention relates to a kind of medical dressing.
Background technology
Medical dressing generally comprises adhesive-layer, base cloth and protective layer, and it is covered on wound surface by protective layer, stops the further infection of wound.By improving composition, the structure of protective layer, improve its infection promoting healing effect and become problem to be solved in prior art.
Nano zine oxide, be widely used in externally used antimicrobial antiinflammatory field as novel nano medical material, but nano material has it to use limitation, skin surface has breakage, nanoparticle enters human body, thereby easily stimulate the immune system of human body to produce potential untoward reaction, these defects have limited the application of the medical nano material including nano zine oxide greatly.
Summary of the invention:
The invention provides a kind of dressing with nanometer zinc oxide composite antibiosis layer, there is base cloth 1, base cloth inner face is coated with adhesive-layer 2, on the adhesive-layer of base cloth middle part, be pasted with protective layer 3, on protective layer, be covered with from paper 4, be fixed on the exposed parts that base cloth periphery is corresponding from paper outer rim, it is characterized in that described protective layer is divided into three layers, comply with apart from base cloth by the nearly nano zine oxide composite bed 3.1 that is extremely far followed successively by, spongy tissue layer 3.2, non-woven fabrics enhancement Layer 3.3, described nano zine oxide composite bed thickness is 0.5-1mm, form by the mode that is evenly coated with nano zinc oxide particles 3.12 in polymeric substrates 3.11, the D90 particle diameter of described nano zinc oxide particles is 30-50nm.Described polymeric substrates preferably adopts polylactic acid, and nano zinc oxide particles is fixed in polymeric substrates by bonding or heating fixed form.
Dressing provided by the present invention; adopt composite protection layer; in sponge tissue layer bottom, be provided with nano zine oxide composite bed, in order to prevent the excessive release of nano zine oxide; can give full play to again its antibacterial action; the dressing of making like this, after wrapping, can discharge nano zine oxide slowly; can continue to bring into play antibacterial action, therefore can wrap up for a long time without changing dressings.
Brief description of the drawings:
Fig. 1 is for the invention provides dressing overall structure schematic diagram
Fig. 2 is protective layer internal structure schematic diagram
Detailed description of the invention
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention, can not be interpreted as the restriction to embodiment of the present invention.
Dressing as shown in Figure 1, has adhesive-layer 2 on base cloth 1, on base cloth 1 middle part adhesive-layer 2, be pasted with overcoat 3, is coated with from paper 4 on protective layer 3, is fixed on the exposed parts that base cloth 1 periphery is corresponding from paper 4 outer rims.
Protective layer internal structure as shown in Figure 2, comply with apart from base cloth 1 by the nearly nano zine oxide composite bed 3.1, spongy tissue layer 3.2, non-woven fabrics enhancement Layer 3.3 of being extremely far followed successively by by described protective layer 3.Nano zine oxide composite bed is divided into polymeric substrates 3.11 and applies the nano zinc oxide particles 3.12 on it.
