Abstract
The utility model relates to medical dressing technical fields; particularly belong to a kind of visual Wound dressing; it is followed successively by back sheet, functional layer and protective layer from top to bottom to form, the functional layer is in rectangular-ambulatory-plane structure, and the center is the visual layers containing hydrophobic particle; it is adsorption layer at frame; the healing state of the surface of a wound can be observed at any time for 24 hours, and there is good absorbency, the diffusate of the surface of a wound can be absorbed; anti- impervious liquid or oozing of blood prevent trauma surface infestation in surface of a wound remained on surface.
Description
Technical field
The utility model belongs to medical dressing technical field, particularly belongs to a kind of visual Wound dressing.
Background technique
Dressing is a critical function of Morden wound dressing, is the critical function that replace damaged skin, and one
It is straight to act on to wound healing.It can resist mechanical factor (such as foul, collision, inflammation), resist pollution and chemical stimulation；It prevents
Subinfection again；Wound healing process is actively influenced by debridement, creates the microenvironment for promoting wound healing.
After dressing, the healing state of the surface of a wound is if desired observed, could be observed after needing to tear dressing, and changed new
Dressing, in this way, not only increasing medical treatment cost, and when more change dressings, patient pain can be made, repeatedly more change dressings can increase
Add the pain of patient.But if most of dressing can make wound and wound circumference because gas permeability is bad using overlong time
Skin whitening, softening leads to the secondary infection of bacterium, can thus wound be made more to deteriorate.Meanwhile for wound or
When the surface of a wound contains large area sepage, most of dressing is due to imbibition ability deficiency, and sepage remains in surface of a wound surface, on the one hand not
Conducive to wound or wound healing, the lesion of bacteria breed is on the other hand formed.
It now needs that a kind of absorption sepage ability is good, good permeability, and the healing state of the surface of a wound can be observed after sepage absorption
Medical 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 visual Wound dressing, can be for 24 hours
The healing state of the surface of a wound is observed at any time, and there is good absorbency, can absorb the diffusate of the surface of a wound, anti-impervious liquid or oozing of blood
In surface of a wound remained on surface, prevent trauma surface infestation.There is good gas permeability simultaneously, be conducive to the rapid evaporation of diffusate, promote
Surface of a wound respiration provides wet healing environment for the surface of a wound, promotes the healing of the surface of a wound.
To achieve the goals above, technical solution provided by the utility model are as follows: a kind of visual Wound dressing of offer, from
Top to bottm is successively made of back sheet, functional layer and protective layer, and the functional layer is in rectangular-ambulatory-plane structure, and the center is containing thin
The visual layers of hydrophilic particles are adsorption layer at frame.
Preferably, spongelike structure is prepared by chitosan and alginates in the adsorption layer.
Preferably, transparent netted sponge films are prepared by chitosan, alginates and hydrophobic particle in the visual layers
Structure.
Preferably, the hydrophobic particle is silica.
Preferably, the back sheet is provided with medical pressure-sensing gluing by the contact surface of adsorption layer and back sheet with functional layer
It closes.
Preferably, the back sheet is with gas permeability transparent polyurethane film.
Preferably, the protective layer is release paper.
Utility model has the advantages that (1) the utility model is provided with functional layer, the functional layer is by visual layers and absorption
Layer composition, the visual layers containing hydrophobic particle can guide the peripherad adsorption layer of the liquid of absorption, guarantee the height of visual layers
Pellucidity is spent, allows to observe the healing state of the surface of a wound at any time, can be decided whether more according to the actual conditions of wound healing
Wound dressing is changed, to reduce the number of unnecessary replacement wound dressing, mitigates the pain of patient.(2) functional layer has by shell
The adsorption layer of spongelike structure made of glycan, alginates has good absorbency, the diffusate of the surface of a wound can be absorbed, and prevents
Impervious liquid or oozing of blood lead to trauma surface infestation in surface of a wound remained on surface.(3) the utility model also has good gas permeability, favorably
In the rapid evaporation of diffusate, promotes surface of a wound respiration, wet healing environment is provided for the surface of a wound, promotes the healing of the surface of a wound.
(4) the utility model structure is simple, and has good biological safety.

Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
Embodiment 1:
As shown in the figure: a kind of visual Wound dressing is successively made of back sheet 1, functional layer 2 and protective layer 3 from top to bottom,
The functional layer 2 is in rectangular-ambulatory-plane structure, and it is adsorption layer at frame that the center, which is the visual layers 21 containing hydrophobic particle 211,
22；Spongelike structure is prepared by chitosan and alginates in the adsorption layer 22；The visual layers 21 are by chitosan, alginic acid
Transparent netted sponge films structure is prepared in salt and hydrophobic particle 211；The hydrophobic particle 211 is silica；Institute
It states back sheet 1 medical pressure sensitive adhesive 4 is provided with by the contact surface of adsorption layer 22 and back sheet 1 with functional layer 2 and be bonded；It is described
Back sheet 1 is with gas permeability transparent polyurethane film；The protective layer 3 is release paper.
Finally, it should be noted that obviously, above-described embodiment is merely examples for clearly illustrating the present invention,
And it does not limit the embodiments.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.And thus
Changes and variations that derived from still in the protection scope of the utility model among.
