Description

A kind of dressing

Technical field

This utility model relates to field of medical products, in particular to a kind of dressing.

Background technology

Dressing is the articles for use of bag wound, in order to cover the medical material of skin ulcer, wound or other infringements, availablely for the protection of wound, avoids by cause pathogeny imcrobe infection, reduces patient's pain.

Traditional dressing is generally with medical de-gauze, cotton pad and kpetrolatum gauze, and these dressing have dressing easily and wound adhesion, damage newborn granulation tissue and cause pain; The shortcomings such as the rear barrier action of dressing infiltration is poor, easily causes exogenous infection, and haemostatic effect is poor.

In order to overcome these shortcomings, some novel dressing on the market at present, as chitosan class, extra large bath Barbiturates, thin film class, foam class etc., these dressing are all single layer structure substantially, only on original traditional dressing basis, increased a part of single function, such as the absorbability of antibiotic property, transudate, breathability, promotion healing etc.

Utility model content

The purpose of this utility model is to provide a kind of dressing, to solve the above problems.

A kind of dressing is provided in embodiment of the present utility model, has comprised: dressing layer;

Dressing layer is included in the wound surface formation silicone layer of oil film, the absorbed layer of the antibiotic layer of pathogenic microbe killing and absorption wound fluid; Silicone layer, antibiotic layer and three layers of mutual pressing of absorbed layer form.

Preferably, the sequence successively from the top to the bottom of silicone layer, antibiotic layer and absorbed layer is absorbed layer, antibiotic layer and silicone layer, and wherein silicone layer spreads on wound.

Preferably, also comprise protective layer, protective layer and silicone layer are fitted mutually.

Preferably, the surface of described silicone layer, described antibiotic layer and described absorbed layer is provided with mesh.

Preferably, described antibiotic layer is that raw material is made by quaternary ammonium salt.

Preferably, described antibiotic layer is that raw material is made by chitosan.

Preferably, described absorbed layer is that raw material is made by PVP.

Preferably, described dressing layer is any one in tetragon, pentagon and circle.

A kind of dressing that this utility model embodiment provides, compare with dressing of the prior art, it is the dressing with trilamellar membrane structure, had simultaneously antibiotic property, long-lasting, antiseized, ventilative, absorb transudate, hemostasis and promote the effect of healing, overcome the shortcoming of effect is single on the market dressing.

The specific embodiment

Below by specific embodiment, also by reference to the accompanying drawings this utility model is described in further detail.

A kind of dressing is provided in embodiment of the present utility model, as Figure 1-4, has comprised: dressing layer;

Dressing layer is included in the wound surface formation silicone layer of oil film, the absorbed layer of the antibiotic layer of pathogenic microbe killing and absorption wound fluid; Silicone layer 3, antibiotic layer 2 and 1 three layers of mutual pressing of absorbed layer form.

A kind of dressing that this utility model embodiment provides, it is the dressing with trilamellar membrane structure, had simultaneously antibiotic property, long-lasting, antiseized, ventilative, absorb transudate, hemostasis and promote the effect of healing, overcome the shortcoming of effect is single on the market dressing.

Three stacked being added together, can form to be firmly attached to and on wound surface, have resisting pathogenic microbes, absorption and transport transudate, promote the long acting antibiotic dressing of healing.

Preferably, the sequence successively from the top to the bottom of silicone layer 3, antibiotic layer 2 and absorbed layer 1 is absorbed layer 1, antibiotic layer 2 and silicone layer 3, and wherein silicone layer spreads on wound.

Silicone layer 3 is organosilicon, can form Si-O key with skin, firmly at skin, forms oil film, avoids dressing and wound adhesion, therefore preferably spreads on the nearest the inside of inner skin.

Antibiotic layer 2 can pass through physical action pathogenic microbe killing, plays antibacterial action, is therefore preferably put in intermediate layer to keep out the intrusion infected wound of antibacterial.

Absorbed layer 1 passes through to absorb the transudate of wound surface, and transudate is transported out to dressing outside, is therefore preferably put in outermost layer to absorb the transudate of wound.

Preferably, also comprise protective layer 4, protective layer 4 is fitted mutually with silicone layer 3, and protective layer can protect dressing when not using, guarantee its effect and avoid and the direct contact stain of atmosphere.

Preferably, the surface of described silicone layer 3, described antibiotic layer 2 and described absorbed layer 1 is provided with mesh, and the surface of each layer is provided with mesh for the breathability of wound.

Preferably, described antibiotic layer 2 is that raw material is made by quaternary ammonium salt, and quaternary ammonium salt has good antibacterial sterilization effect,

Preferably, described antibiotic layer 2 is that raw material is made by chitosan, and chitosan has following characteristic: chitosan is easy to dissolve in weak acid solvent, contains amino (NH in the solution after dissolving ₂ ⁺), these amino are by carrying out anti-bacteria in conjunction with negatron, so bactericidal effect is fine and nontoxic.

Preferably, described absorbed layer 1 is that raw material is made by PVP, and polyvinylpyrrolidone has good physiology inertia, to human body without any stimulation, have removing toxic substances, stop blooding, improve concentration of ordinary dissolution, prevent peritoneal adhesion, promote the effects such as erythrocyte sedimentation rate, the effect that therefore absorbs sepage is very good.

Preferably, described dressing layer is any one in tetragon, pentagon and circle, and dressing can be made arbitrary shape according to actual needs.

The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
