Description
Technical field
The utility model belongs to medical dressing technical field, particularly belongs to a kind of compound wire side medical dressing.
Background technique
Most of dressing wound healing ability is limited, generally requires longer time healing, increases patient and doctor
The pain of business personnel.If using overlong time, because gas permeability is bad, the skin whitening of wound and wound circumference can be made, become
The soft secondary infection for leading to bacterium, can thus be such that wound more deteriorates.Meanwhile big face is contained for wound or the surface of a wound
When product sepage, due to imbibition ability deficiency, sepage remains in surface of a wound surface for most of dressing, be on the one hand unfavorable for wound or
On the other hand wound healing forms the lesion of bacteria breed.And most of dressing is not easy to observe the surface of a wound in use
Healing state could be observed after needing to tear dressing, and change new dressing, in this way, medical treatment cost is not only increased, and
When more change dressings, patient pain can be made, repeatedly more change dressings will increase the pain of patient.
Existing functional dressings are not able to satisfy clinical demand mostly in market, such as burst especially for some chronic wounds
Ulcer, diabetes, bedsore etc. are more the absence of effective functional dressing.
Utility model content
The purpose of the utility model is to overcome the defects of the above-mentioned prior art, provide a kind of compound wire side Medical coating
Material can remarkably promote the healing of the surface of a wound, and have good absorbency, gas permeability, antibiotic property, while caning absorb when dressing
After layer is absorbed by the surface of a wound, the healing state of the surface of a wound can be observed for 24 hours.
To achieve the goals above, technical solution provided by the utility model are as follows: a kind of compound wire side of offer is medical
Dressing is made of back sheet, liquid-adsorption layer, absorbable layer and protective layer, and the liquid-adsorption layer is in rectangular-ambulatory-plane structure, and the center is
The visual layers of bright mesh sponge membrane structure are the adsorption layer of spongelike structure at frame, and the visual layers are by the poly- ammonia of hydrophobicity
Ester is prepared, and the adsorption layer is prepared by hydrophilic polyurethane, and the absorbable layer is pigskin acellular dermal matrix.
Preferably, adsorption layer load has silver ion.
Preferably, the back sheet is provided with medical pressure-sensing gluing by the contact surface of adsorption layer and back sheet with liquid-adsorption layer
It closes.
Preferably, the back sheet is highly-breathable and transparent polyurethane film.
Preferably, the protective layer is release paper.
Preferably, the backing layer surface is provided with micropore.
Preferably, the visual layers and adsorption layer are prepared in same mold, are an overall structure.
Preferably, the absorbable layer and visual layers area equation.
Utility model has the advantages that (1) the utility model is provided with liquid-adsorption layer, the functional layer is by visual layers and absorption
Layer composition, visual layers can guide the peripherad adsorption layer of the liquid of absorption, guarantee the highly transparent state of visual layers, so that can
To observe the healing state of the surface of a wound at any time, can be decided whether to replace wound dressing according to the actual conditions of wound healing, to subtract
The number of few unnecessary replacement wound dressing, mitigates the pain of patient.(2) it is provided with pigskin acellular dermal matrix, it can be by
The surface of a wound absorb, promote cell stick and growth, remarkably promote the healing of the surface of a wound.(3) the utility model also has very well
Gas permeability, be conducive to the rapid evaporation of diffusate, promote surface of a wound respiration, wet healing environment is provided for the surface of a wound, rush
Into the healing of the surface of a wound.(4) this is practical also with good antibacterial effect, can kill the pathogenic bacteria of the surface of a wound, prevent trauma surface infestation.
Detailed description of the invention
