Description

Scar plaster

Technical field

This utility model relates to medical and beauty treatment material technology field, relates in particular to a kind of scar plaster.

Background technology

Behind burn, wound or the surgical operation, patient often forms scar hyperplasia or keloid on surface, wound healing place, and except affecting the outward appearance beauty treatment, serious meeting causes limbs disturbance, even may canceration.Since the 1980s, after the effect that the silicon gel can soften cicatrix is found, the various countries scholar has carried out a large amount of research, proof silicone product really can be to cicatrix a lot of medical silicone products that played preventive and therapeutic effect and utility model, started the new situation of non-operative treatment treatment scar hyperplasia, most widely used is silicone gel paster.

The material of silicone gel paster itself is the medical silica-gel of single component, without other adding ingredient.Action principle is by the sealing of silica gel to skin, forms the protecting film of permeable watertight, and the moisture at cicatrix place is outwards distributed, and repairs cicatrix thereby form hydration with skin.Simple silicon gel has good preventive and therapeutic action to hypertrophic cicatrix, but treatment cycle is longer, generally needs more than 3 months.And this series products has the following disadvantages: 1, by the passive sealing moisture of silica gel, cicatrix skin is not had the initiatively function of moisturizing, by to the hydration of cicatrix skin and passive reparation cicatrix, rather than initiatively promote the change of cicatrix skin texture; 2, wound surface is not had repair function, the skin on cicatrix surface is incomplete, also exists and does not repair fine cracks; 3, simple silicon gel preparation does not have antiinflammatory action, and the cicatrix body often reacts with light inflammation; 4, the silicon gel does not have clear and definite direct effect effect to fibroblast and the collagen fiber that suppress in the cicatrix body.

Hyaluronic acid (Hyaluronic acid is abbreviated as HA) has another name called Hyaluronic Acid, is the important component in the extracellular matrix aminoglycan.In wound healing, hyaluronic acid has been proved has following effect: 1, keep extracellular space, bring into play conformation function with the grumeleuse that fibrin forms in wound healing process; 2, low-molecular-weight hyaluronic acid has the effect of antiinflammatory, inhibition pathological reaction; 3, the CD44 receptors bind of hyaluronic acid and epidermal surface, the normal differentiation of promotion epidermis cell.4, low-molecular-weight hyaluronic acid promotes angiogenesis; 5, regulation and control collagen is synthetic.The Histological research that is directly used in wound face has proved that also the external source hyaluronic acid can activate the granulation tissue generation and papilla cell occurs.In addition, the water conservation of HA excellence, lubricating ability and tissue adhesion's effect thereof also provide foundation for its effect in the extensive wound treatment.But, have not yet to see the cicatrix that hyaluronic acid is combined with the silicon gel and repair product.

The utility model content

Technical problem to be solved in the utility model is, a kind of scar plaster is provided, fast and effeciently to repair cicatrix.

For solving the problems of the technologies described above, this utility model provides following technical scheme: a kind of scar plaster, it comprises the back end layer that stacks gradually applying from top to bottom, medical glue-line, the first silicon gel layer, the first hyaluronic acid derivatives layer, the second silicon gel layer, the second hyaluronic acid derivatives layer and separate paper.

Further, described back end layer is pellosil, polyurethane film or non-woven fabrics.

Further, described the first hyaluronic acid derivatives layer and the second hyaluronic acid derivatives layer are the gel film of hyaluronic acid or the preparation of its sodium salt.

Further, described the first hyaluronic acid derivatives layer is to be the gel film that 0.5～500,000 hyaluronic acid or its sodium salt are made by molecular weight.

Further, described the second hyaluronic acid derivatives layer is to be the gel film that 5～2,000,000 hyaluronic acid or its sodium salt are made by molecular weight.

After adopting technique scheme, this utility model has following beneficial effect at least: have simultaneously silicon gel layer and hyaluronic acid layer in this utility model scar plaster, cicatrix had complement each other and collaborative repair, can fast and effeciently repair cicatrix, and by the multiple-layer stacked design, can bring into play quickly and consistently hyaluronic effect.

The hyaluronic acid layer can be accelerated union of wounded skin initiatively to skin moisture-keeping, antiinflammatory, the effects such as collagen synthesizes in the regulation and control scar tissue; During use, tear separate paper off, directly be attached on the skin with the second hyaluronic acid derivatives layer, but hyaluronic acid rapid osmotic and act on the skin scar tissue, the second hyaluronic acid derivatives layer selects polymer hyaluronic acid or its sodium salt of 5～2,000,000 molecular weight to make, and effect is better; And the first hyaluronic acid derivatives layer is that 0.5～500,000 low-molecular-weight hyaluronic acid or its sodium salt are made by molecular weight, can effectively permeate and see through the second silicon gel layer, the second hyaluronic acid derivatives layer is played supplementary function, reach and to act on scar tissue by the sustained release hyaluronic acid again fast.
