Core periphery is formed in the alginate dressing of flaabellum shape, and the functional layer is circle, is set to round deposited core middle position, and area is less than
Apply the area of core.The center of adhered layer, liquid-adsorption layer and functional layer is set for circle, when in use, liquid-adsorption layer is selected to apply core area
Slightly larger than the dressing of surface of a wound area, liquid-adsorption layer is applied into core and functional layer is directed at the surface of a wound, is on the one hand conducive to flap coverage, another party
The diffusate of the surface of a wound can be absorbed in face, forms gel, the healing environment for keeping the surface of a wound wet；In adhered layer and liquid-adsorption layer setting fan
On the one hand blade profile periphery can absorb extra diffusate on the outside of the surface of a wound, on the other hand can not only guarantee the ventilative of dressing
Property, and can position according to the surface of a wound and shape, the position of automatic adjusument application.
Further, the adhered layer is polyurethane film, and inner surface is coated with medical pressure sensitive adhesive.
Further, the adhered layer flaabellum shape structure and liquid-adsorption layer flaabellum shape parallelism structural, and adhered layer flaabellum shape knot
Structure area is greater than liquid-adsorption layer flaabellum shape structural area.Setting can guarantee that liquid-adsorption layer can be completely covered in adhered layer in this way, can be with
It prevents bacterium from entering, prevents from infecting.
Further, there is gap between the flaabellum shape structure of each layer.
Further, the deposited core of the liquid-adsorption layer is alginate foam dressing, and the diameter for applying core is 1-25cm.Liquid-adsorption layer
With good absorbency, a large amount of diffusate of the surface of a wound can be absorbed
Further, the functional layer is the alginates medical films of silver ion.Alginates film has certain absorbency,
After absorbing diffusate, gel can be formed, wet healing environment is provided for the surface of a wound, while silver ion has sterilization effect well
Fruit can prevent trauma surface infestation, and sterile healing environment is provided for the surface of a wound, and the two collaboration promotes the healing of the surface of a wound.
Further, the diameter of the functional layer is 0.5-20cm.
Further, the protective layer is release paper.
Compared with prior art, the utility model has the following beneficial effects:
1, the utility model structure is simple, has outstanding adaptivity, is adapted to the packet of the human body different parts surface of a wound
It pricks and fixes, especially the irregular position of the forms such as iliac region, armpit area, hinge area；
2, the utility model has good absorbency, antibiotic property, moisture retention, gas permeability, can remarkably promote being cured for the surface of a wound
It closes, it is better than general medical dressing functional effect, it can satisfy the demand of clinical use.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is that the utility model removes structural schematic diagram after protective layer.
Specific mark explanation: adhered layer 1, liquid-adsorption layer 2 apply core 21, alginic acid dressing 22, functional layer 3, protective layer 4.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
A kind of self-adaptation type alginate dressing, successively by adhered layer 1, liquid-adsorption layer 2, functional layer 3 and protective layer 4 from outside to inside
Composition, 1 center of adhered layer is rounded, and periphery is distributed in flaabellum shape, and the liquid-adsorption layer 2 is applied core 21 by the circle at center and divided
