Abstract

primary and secondary wound dressing characterized in that a transparent, with perforation (3) formed PE film (4) wound-side with an antimicrobial coating (5), an anti-adhesive Coating (11) and a wound healing coating (12) provided is and itself or associated with foams, nonwovens (13), gauze (9) or a transparent adhesive film (1) applied as a wound dressing becomes.

Description

  • The present invention is a primary and secondary, transparent, perforated wound dressing that is antimicrobial and antiadhesive coated on the wound and with foam, knitted fabric and Nonwoven is bonded cohesively.
  • The Treating open wounds that are too big to be spontaneous closing again has long been a problematic one Area in medicine.
  • wound closure an open wound requires the immigration of the surrounding epithelium and subcutaneous tissue.
  • Some But wounds are so big or infected that a spontaneous cure is impossible. In these cases forms close the wound surface is a stasis zone in which the blood circulation of the epithelial and subcutaneous tissue through a localized edema is hampered. Without sufficient blood flow is the wound unable to effectively combat bacterial infections and to close spontaneously accordingly.
  • A incipient wound healing phase is due to the formation of granulation tissue characterized. This granulation tissue is a matrix of collagen, Fibronectin, hyaluronic acid-bearing macrophages, fibroblasts and newly formed vessels that are the foundation for the subsequent epithelization of the wound forms.
  • The Formation of granulation tissue in the wounded tissue and thus also Wound healing is caused by infections and inadequate vascularization with special needs.
  • Therefore It is desirable to find a technique that improves blood circulation reinforced in the wounded tissue, so as a spontaneous healing to promote and reduce the risk of infection.
  • bad Blood circulation and infection of the wound can be over it In addition, the attachment of skin grafts or Kutislappen on complicate the wounded tissue. Skin grafts and cuticle lobes do not adhere to poorly vascularized, infected or necrotic Tissue.
  • At wounded tissue capable of forming granulation tissue However, skin grafts and cuticle lobes can be essential be installed more successfully. Thus, a technique would to promote blood circulation in wounded tissue as well the successful attachment or "acceptance" of skin grafts or Kutislappen on wounded tissue because grafts or Cuticle flaps are better supplied with blood.
  • Also Wounds caused by ischemia or circulatory disorders are often difficult to cure because the normal Immune reaction of the body to fight the infection can be suppressed by the reduced blood flow.
  • Bedridden Patients or patients whose mobility is out other reasons are limited for ischemic wounds, such as. B. decubital or pressure ulcers, susceptible. Decubital ulcers are caused by constant Compression of the skin surface and the underlying Tissue and thus constant restriction of blood circulation.
  • There the patient often does not feel the wound or can not move enough to relieve the pressure point, Such wounds can form again and again.
  • Even though such wounds are often treated with cuticle can the states that originally responsible for the genesis of the wound, too prevent the successful attachment of the cuticle flap.
  • At the wheelchair bound paraplegic z. B. must even after treatment of pressure ulcers in the pelvic area maintain their sitting position. Therefore, it is desirable to provide a treatment for ischemic wounds, in situ on a motionless or only partially mobile patient.
  • Other Wounds in which ischemia progressively worsening leads are second-degree burns.
  • at second degree burns, cell death is due to of thermal trauma not under the deepest epidermal structures like z. Hair follicles, sweat glands or sebaceous glands.
  • The Progression of second degree burns to deeper burns represents a big problem in the treatment. If Controlled the depth of the burns or can be diminished, the prognosis for the Patients much better and those due to the combustion Mortality diminished.
  • Second degree burns are formed by a coagulation zone containing tissues killed by the burn and a stasis zone. The stasis zone is a tissue layer unmit directly below the coagulation zone. The cells in the stasis zone are viable, but blood flow is static because vascular structures collapse due to localized edema.
  • If the blood circulation in the stasis zone not soon after the injury is restored, the tissue in this zone also dies. The tissue death in the stasis zone is due to a lack of oxygen and nutrients, through reperfusion (recovery blood circulation after prolonged ischemia) Injuries and diminished immigration of white Blood cells in the zone and thus proliferation of bacteria caused. Again, it is desirable, a To provide technology to treat burns, by improving blood circulation in wounded tissue to curb the penetration of combustion.
  • One Another problem in wound treatment is the selection of a appropriate wound insert or wound dressing.
  • The Dressing material must be sufficient for the drainage of the secretion be permeable and not allow the wound through hard Irritate material. When cutting the material for the existing wound size there must be no formation of Give fibers or foam crumbs, which grow into the wound could.
  • Therefore it is beneficial to use a material that is bioactive, antimicrobial acts, does not hinder the drainage flow under vacuum, hard and cuddly and at 1 cutting to adapt to every wound size does not fuzz, does not crumble, Say no free, small segments for wound contamination secretes.
  • In the DE 694 25 881 A foam is used as a wound dressing, which crumbles when cutting and forms sharp edges.
  • In DE 695 05 545 . DE 296 23 482 . DE 695 28 716 . EP 12 19 311 . GB 95,01983 . WO 96 10 5873 . DE 601 18 546 . DE 92 19 136 . DE 692 24 847 In all of these inventions it is preferred to use a porous foam or mullein.
  • Out DE 692 29 940 a foam pad suitable for bonding a wound is used. This pad is adapted to the wound dimensionally stable.
  • in the DD 297 914 The invention relates to a plaster as a quick bandage for wound treatment by targeted delivery of drugs. In order to enable the immediate delivery of active ingredients in liquid or pasty form in the actual amount required and regardless of the whereabouts of the person to be treated, according to the invention a reservoir is introduced in a sticking plaster between the cover layer and the upper layer of the compress.
  • The Reservoir can thus either in the compress or between the Compress and the top layer lie. In the reservoir is an active ingredient contained in a liquid or pasty Substance is dissolved. The material of the reservoir is for the passage of the active substance and the substance in which it is dissolved is impermeable. By finger pressure becomes the reservoir destroyed and the drug soaks the compress.
  • In the DD 268 397 The invention relates to a process for the preparation of local administration forms for the treatment of skin damage, for example second or third degree burns. Application forms are preferably patches, gauze bandages or gauze pieces coated or impregnated with a curative composition. The method is characterized in that 12 to 25% wax, 60 to 88% pharmacologically acceptable 01, 1 to 15% of a cooling ethereal substance and optionally a maximum of 5% with the other components compatible active ingredients mixed together and homogenized, whereupon with the homogeneous mass textile carrier or plastic carrier soaks or sweeps and packaged the so impregnated carrier sterile.
  • For example serves as a wax beeswax or wool wax, as an oil paraffin, Sunflower or castor oil or mygliol or mixtures thereof, as cooling ethereal substance camphor or Menthol and as an active ingredient an antiseptic or a chemotherapeutic agent, preferably antibiotic.
  • Furthermore, in the DE 10 2004 022 645 discloses a bioresorbable collagen-based material having a content of a linear polymeric biguanide and / or a water-soluble salt thereof. Preferably, the biguanide is polyhexamethylene biguanide. The bioresorbable material can be used in the form of a wound dressing or as a wound or bone implant. It is extremely compatible and leads to a quick and uncomplicated wound healing with a significantly reduced risk of infection.
  • In the main claim of DE 20 2004 007 971 U1 a triangular absorbent pad is characterized in that square blanks of gauze with different side lengths, preferably between 9 cm and 15 cm, individually or two superimposed, ge over the diagonal folded so that an isosceles triangle is formed, from which the lower tip is placed upside down and turned at an angle of about 75 degrees to the left, so that below a pointed bag is formed, in which the gauze in parallel planes or "Layers" is triangular, and which is suitable to take the above projecting tips, which are to be turned down, so that more parallel planes are added or the "Lagigkeit" is increased.
  • Object of the invention DD 252 950 is to develop a medical wound dressing with resilient compliance, defined gas permeability, protection against bacteria and good lyophil properties. The medical wound dressing should consist of a front and back of flexible polyurethane foam. The object is achieved in that an open-cell polyurethane flexible foam film, having a thickness of 1.2 to 3 mm, is melted on a surface without thermal decomposition and with a 10 to 30 times irreversibly compressed flexible polyurethane foam film, having a thickness of 0.1 to 0.4 mm, gas and water vapor permeable is connected.
  • The invention DD 145 062 relates to a transparent fluid dressing material, in particular for the treatment of wounds and for use in cosmetics, dentistry and for cell cultures. According to the invention, the liquid dressing material is present as a dried, swellable, clear film of a hydrophilic, organic, transparent gel in sheet or ribbon form, which may contain buffer substances, conventional wound care agents, nutrients and / or growth substances, and optionally a line or netlike arranged arranged reinforcing material. The gel according to the invention consists of a mixture of hydrophilic polymer and at least one gellable high molecular weight substance. It consists for example of a gellable polysaccharide and / or protein or polypeptide and a polymer of a hydrophilic acrylic or methacrylic acid derivative, which was prepared by polymerization in the presence of the polysaccharide and / or protein or polypeptide. In particular, the gel consists of 50 to 90% by weight of polymerized acrylic or methacrylic acid derivative and 50 to 10% by weight of polysaccharide and / or protein.
  • In addition, a stiff wound cap in the DD 222 497 described. The wound covers should preferably be used in operating clinics. The range of application is extended by applications in internal diseases, skin diseases, thermal injuries and in experimental surgery. The transparent, lightweight and preferably made of thermoplastics such as polymethyl methacrylate, polyethylene, polystyrene, polyacrylonitrile, polyamides or polyvinyl chloride wounds allow a wound care, the wounds come into contact only with the medium air. Free air access to the wound eliminates a number of technical and economic disadvantages inherent in traditional wound dressings. The method also has the goal to reduce reservations, which were repeatedly brought to the open wound treatment.
  • In the GB 20 2008 000 102.1 is a knitted fabric or a gauze is described, which avoids linting when cutting with a drenching layer.
  • The GB 20 2008 000 101.3 describes a perforated film which is coated towards the wound and cohesively connected with other materials represents a complete wound dressing.
