Abstract
The utility model relates to a bacteriostatic fiber self-adhesive wound dressing which includes a base material layer formed by a non-woven cloth obtained through blending modified or unmodified chitosan fiber or modified cellulose fiber, an adhesive layer with the periphery formed by adhesives, and a release paper. The bacteriostatic fiber self-adhesive wound dressing can absorb the wound secretion while inhibit the growth of the bacteria in the wound, and is particularly suitable for treating chronic wounds.
Description
Technical field
This utility model relates to a kind of high moisture absorption wound dressing that has biocidal property.
Background technology
As everyone knows; When selecting wound dressing to handle wound; A right difficult problem of nursing staff's demand side is when handling the chronic wounds transudate, also will offer the favourable healing environment of wound; These advantageous environment conditions comprise that it is moistening with the maintenance wound to absorb the wound juice, can suppress the microorganisms grow of wound simultaneously effectively.
Chitin fiber has bacteriostasis efficacy, wherein the NH of chitosan
2The positive charge that group has combines with the negative charge of bacteria cell wall, thus bacteria growing inhibiting.In addition, the micromolecule chitosan penetrates cell wall and comes the formation of inhibitory enzyme with this.This is easy to observe in general bacteriostatic test; When being positioned over chitosan non-woven fabrics sample in the zone that the culture dish that scribbles antibacterial can observe after 24 hours below the non-woven fabrics is " cleaning "; Promptly in the zone of chitosan non-woven fabrics, there is not the growth of antibacterial; And can observe antibacterial obvious growth is arranged, explain that thus chitin fiber possesses bacteriostasis efficacy in the zone of non-chitosan non-woven fabrics.Through after the chemical modification, after doing the processing of hydrophilic treated or hygroscopicity, the hygroscopicity of fiber more can improve but the while has also kept the bacteriostasis property of chitosan chitosan.
Usually the wound dressing that has antibiotic effect in the art also comprises argentiferous class wound dressing, but this type wound dressing all obviously has certain toxicity.
Yet the inventor notices up to now, still has the demand to the wound dressing of the high hygroscopic property of the bacteriostasis property that has chitosan simultaneously and modified cellulose.
The utility model content
This utility model is that a kind of high moisture absorption self-adhesion that has biocidal property pastes wound dressing, adhered layer and release paper that it comprises substrate layer that the non-woven fabrics that obtained by chitin fiber modification or unmodified and modified cellulose fibre blending forms, is formed by bonding agent.
This utility model uses chitin fiber modification or unmodified and modified cellulose fibre to be base material.
Especially; This utility model relates to the high moisture absorption self-adhesion of a kind of bacteriostatic fibre class and pastes wound dressing; The base material of this wound dressing is formed by the modified cellulose fibre blending modification of 5-95 weight % or unmodified chitin fiber, 95-5 weight %, in the gross weight of chitin fiber and modified cellulose fibre.To the blending of these two kinds of fibers before fabric forms, such as what realize in fiber carding process or the fiber opening process.
The fiber that this utility model base material uses can be common chitin fiber or chemically modified chitosan.Preferably, modified chitosan fiber is through carrying out chemical modification like carboxy methylation and acylation reaction.
The employed modified cellulose of this utility model base material is a carboxymethyl cellulose fiber, is preferably the cellulose alkyl sulfonation fiber through carboxymethylated solvent-spun cellulose fibre or insoluble in water.
The bacteriostatic fibre class that this utility model relates to is from pasting wound dressing, and it comprises the layer structure that adhered layer that substrate layer that the non-woven fabrics that obtained by chitin fiber modification or unmodified and modified cellulose fibre blending forms, its periphery are formed by bonding agent and release paper are formed.
The fiber that this utility model uses is short fiber, can long filament or fibre cutting be become certain length according to the structure of wound dressing, and said fibre length is 10-125mm.
The fiber that this utility model uses has certain line density and crimpness, and the line density of said fiber is the 0.5-5 dtex.
This utility model is because substrate layer adopts chitin fiber and modified cellulose blending, and dressing has high-hygroscopicity and biocidal property.
Description of drawings
The structural representation that has the high moisture absorption self-adhesion subsides of biocidal property wound dressing that Fig. 1 relates to for this utility model.
Fig. 2 is the profile of the A-A direction of Fig. 1.
The specific embodiment
Below through specific embodiment, and combine accompanying drawing, the technical scheme of this utility model is further specified.
Referring to Fig. 1 and Fig. 2, it has shown the structure of the high moisture absorption self-adhesion dressing that has biocidal property in the specific embodiments of this utility model.The substrate layer 1 that is formed by non-woven fabrics is made up of in adhered layer 2 and the release paper 3 that periphery forms bonding agent.
