Description

Ion type alginate band aid

Technical Field

The utility model relates to a medical dressing field, concretely relates to ion type alginate band aid.

Background

The bandage mainly uses materials such as gauze, cotton pad in early stage, and its shortcoming mainly is "dry therapy", makes the dry environment of wound, is unfavorable for the healing of wound, and this type of material easily glues with the wound in addition, arouses pain during the change, perhaps destroys new skin, causes secondary damage, is difficult for removing after the wound healing, consequently, needs a neotype wound care bandage to solve these problems, improves patient's quality of life.

The English Winter in 1962 finds that the healing speed of the wound surface is faster in a humid environment than in a dry environment, because the humid environment accelerates the migration of epidermal cells from healthy skin to the wound, thereby accelerating the healing speed of the wound, and the alginate dressing, the non-woven fabric and the like are widely applied under the guidance of the 'wet therapy' principle.

Alginate is a natural macromolecule extracted from seaweed, and belongs to polysaccharide substances. In recent years, it has been widely used as a medical material, which has high absorbability and can absorb a large amount of exudates; has easy removability, and can be puffed to form gel after absorbing exudate; the gel has high oxygen permeability, and oxygen can better pass through gel formed by alginate; the hemostatic function, such as calcium alginate, can exchange ions with the wound to release calcium ions, which is helpful for wound hemostasis. When the alginate is used for wound nursing, although the defects of some traditional dressings are overcome, the alginate has a single function, so that the wide application of the alginate is limited.

Disclosure of Invention

The utility model aims at overcoming the defect in the above-mentioned technique, providing an ion type alginate band aid, its simple structure can select the functional material of packing according to the characteristics of wound to can compensate the defect when using alone alginate to protect the wound.

The technical scheme of the utility model is that: an ionic alginate wound dressing comprising a release layer, a binding layer, a dressing layer and an ion-accumulation layer, characterised in that the ion-accumulation layer is "W" shaped in cross-section and the spaces formed by the binding layer and the dressing layer define a first, second, third, fourth and fifth dressing layer.

Furthermore, the coating layer is an alginate non-woven fabric with high porosity.

Furthermore, the surface of the core applying layer is sprayed with an antibacterial active ingredient, and the antibacterial active ingredient is composed of one or more of betaine, carboxymethyl chitosan, chitosan and a solution containing silver ions.

Still further, the ion accumulation layer is a porous PTFE membrane.

Further, the adhesive layer is a low-allergenic medical nonwoven tape.

Furthermore, the stripping layer is glassine silicone oil paper.

Further, the first, second, third, fourth and fifth dressing layers are completely filled between the "W" ion-stacking layer and the dressing layer and the adhesive layer.

Furthermore, the first dressing layer, the second dressing layer, the third dressing layer, the fourth dressing layer and the fifth dressing layer are tightly bonded with the W-shaped ion accumulation layer, the dressing layer and the bonding layer through soft tissue medical glue.

Still further, the tie layer can completely cover the dressing layer, the ion stack layer, and the first, second, third, fourth, and fifth dressing layers.

Still further, the release layer can completely cover the tie layer and the wicking layer.

The utility model discloses following beneficial effect can produce:

(1) the cross section of the ion stacking layer is designed into a W-shaped structure, the space formed among the ion stacking layer, the bonding layer and the dressing layer can be respectively filled with a first dressing layer, a second dressing layer, a third dressing layer, a fourth dressing layer and a fifth dressing layer, the defects of single use of alginate for wound protection can be overcome by the aid of the multiple dressing layers, and filled functional materials can be selected according to characteristics of wounds, so that the dressing has multiple functions.

(2) The utility model discloses wound-plaster on the one hand dressing layer accessible applies the hole of sandwich layer and plays its effect of protecting the wound, and "W" type ion accumulation layer can promote the diffusion and the absorption of dressing layer composition through the charge effect of taking in addition, promotes the microcirculation of blood around the wound to reach the mesh of the quick healing of wound.

(3) The ion accumulation layer has the function of improving the permeability of cell membranes, so that the absorption of active ingredients in the dressing layer by cells can be promoted, and the contact area between the ion accumulation layer and the dressing layer can be increased by designing the cross section of the ion accumulation layer into a W shape.

(4) Alginate that contacts with the wound has the effect of absorbing the sepage, can form one deck thin gel layer on the surface after absorbing the sepage, for the wound provides the moist environment that is favorable to healing, can avoid dressing and wound tissue to take place the secondary damage that the adhesion brought in addition, alginate surface spraying has the composition of antibacterial activity, prevents that the wound from being infected by the bacterium, is favorable to the quick healing of wound.
