    The invention relates to an easy-to-use scar removal patch which is applied to hypertrophic scars and keloids. Due to the permanent pressure of the integrated scar plaster feather a qualitatively constant treatment can be offered for months. Due to the different materials of the upper (3) and lower carrier layers (4), the effect can be enhanced or changed. Also can be initiated by so-called depot structures (6) in the spring base (1) at the same time an additional treatment.

    Description: The invention relates to scar covers with an integrated force-acting spring pressure.
    The invention can be used in plaster form or simple cover.
    The scar cover comprises a scar pad made of a breathable and preferably adhesive polyurethane matrix and optionally a carrier film made of a preferably water vapor-permeable and water-impermeable polymer layer or other layer. In order to exert enough pressure on the scar tissue, an integrated spring (Fig. 1) is built into the cover or plaster.
    [0004] Scar dressings are used over a longer period of time and are not constantly changed like wound care dressings or normal plasters.
    The proven best treatment for hypertrophic scars and keloids is pressure treatment. The pad or plaster with integrated spring exerts permanent pressure on the scar tissue.
    Normal plasters or covers cannot exert sufficient pressure on the scar tissue. Large-scale pressure bandages on scars after heart operations restrict the patient's breathing.
    The scar breaker plaster with integrated spring can locally exert the required force on the scar tissue permanently.
    [0009] WO 2003 080 133 A1 describes plasters for reducing scars. The scar reduction plasters comprise a carrier film made of air and water vapor-permeable and water-impermeable polymer layer, a scar covering made of a breathable and adhesive polyurethane-xerogel matrix, the carrier film being coated over the entire surface with the polyurethane matrix and the outer layer made of the same polyurethane-xerogel matrix is formed, which bevels to the edge to a thickness of a maximum of 5 to 150 pm.
    [0010] EP 2 210 619 A2 describes scar covers with UV protection.
    The present invention has the object to eliminate the disadvantages of the prior art and to provide an easy-to-use application for reducing the hypertrophic scars and keloids. It has to be gentle on the skin, long-lasting, removable without residue and easy to use.
    The scar cover or scar plaster with an integrated force-exerting spring is protected by the spring construction UV light and at the same time exerts a force on the scar tissue.
    Below the force-exerting spring, a backing layer (4) is applied, which comprises a scar covering made of a breathable matrix and optionally a backing film, preferably of water vapor-permeable and water-impermeable polymer layer.
    Below the force-exerting spring, the carrier layer (4) can consist of polyurethane / silicone.
    Below the force-exerting spring, the carrier layer can be perforated (6) with holes, where you can initiate various scar cream substances in so-called depot holes of the force-exerting spring. The active substance is then released over a long period of time with permanent pressure.
    [0016] Below the force-exerting spring, the carrier layer (4) can be self-adhesive.
    By simultaneously printing and delivering the cream or other substances, permanent pressure emulsion treatment of the scar tissue is achieved.
    Above the force-exerting spring is an adhesive skin-friendly carrier layer (3) which surrounds the force-exerting spring with a sufficiently large adhesive edge to apply the plaster to the skin. This adhesive edge keeps the plaster or pad in place so that the force can be applied to the scar tissue by the spring.
    The force-exerting spring is preferably made of medical plastic. The spring can also consist of metal, wood cellulose, fiber composites, or any other material.
    The spring has a so-called spring base (1) which is thinner, the same thickness or thicker than the actual spring construction. The spring base permanently exerts the force on the scar tissue.
    The spring base (1) can be flat, structured or perforated.
    The spring base (1) can have so-called depot structures in which specific scar creams or scar substances are installed. The depot structures (6) can be covered with or without a slowly diffusing film, so that a constant release of the substances is guaranteed.
    The spring arms are pressed down with the application on the skin and remain in position by the self-adhesive lower backing layer (4) or by the self-adhesive edge of the upper backing layer (3).
    By pressing the spring arms down to the level of the skin surface, permanent pressure is exerted on the scar tissue.
    CH 712 998 A2 The pressure on the scar tissue should be permanently at a minimum of 0.001 N / mm 2 . The pressure can be increased with the spring arms to an unlimited extent.
    Depending on the thickness or material properties, the spring arms (2) can be used to generate any permanent pressure on the scar tissue. The pressure is then transferred using the spring base (1).
    The spring base (1) should be as stiff as possible, but can be designed to be flexible, depending on the grain type or application.
    The spring arms (2) have so-called spring torsion holes (5) or none. Spring torsion holes can be made in any shape, such as cylinders, rhomboids, slots. Other shapes are also possible.
    The spring torsion holes (5) ensure that sufficient spring force is transmitted, but the spring arms adapt to the shape of the body despite stiffness. The spring torsion holes can be applied to the entire spring arm (2) or the spring base (1). This can have a lasting effect on the properties of the spring.
    The spring base (1) and the spring arms (2) must have skin-compatible edges, such as rounded edges or edges with cushion pads in any skin-compatible material.
    The scar cover according to the invention reliably and completely protects fresh scar tissue from harmful influences.
