Definitions

  • the invention relates to a wound dressing with a wound swab which can be applied to a wound, a pressure swab for pressing the swab against a wound and a fastening means for local fixation of the wound dressing in the area of the wound in accordance with the preamble of claim 1.
  • the invention relates in particular to a rapid wound dressing, a fast wound plaster or a compression bandage for rapid wound care.
  • a rapid wound dressing a fast wound plaster or a compression bandage for rapid wound care.
  • it is a compression plaster, which quickly stops bleeding through metered compression, without stopping the blood circulation in the tissue.
  • Such compression bandages are such.
  • venous catheter / Braunülen implant wounds are required for taking blood samples. Small wounds and cuts
  • a wound To stop bleeding after taking blood, a wound must be taped slightly compressively. In addition, the formation of "bruises" should be prevented.
  • a gauze swab is glued to an approx. 7 x 7 cm fixomull blank. This unit is glued to the wound. As a support, the patient holds his thumb on the patch to support the light compression. If cannulas and tubes are placed on the patient, several individual components are used. A combination of a gauze swab and an inelastic adhesive carrier is usually used for permanent fixation.
  • pressure is also required to relieve the surrounding veins after the obliteration of individual sick vessels or after the surgical removal.
  • This pressure is often achieved by elastic bandages that are wrapped around the treated areas and at the same time fix the wound fabric flat and firmly over the vulner ulcer.
  • the metered pressure is intended to promote the circulation in the vessels and thus facilitate the work of the venous valves. Problems generally arise in areas around joints on the musculoskeletal system. There it is often not possible to guarantee the necessary pressure and maximum freedom of movement at the same time.
  • Wound plasters have already been developed and optimized in many forms and conceivable variations.
  • surgery for example laparoscopy
  • the reversible expansion of a material can be used to fill the openings and cavities after the organ has been removed. Due to the deformable flexible It is possible to insert this material into the patient through the smallest surgical openings and to remove it again (US Pat. 6,080,168). This supports the tissue close to the surgical field and separates it from the surgical site.
  • Another application uses a compressive sponge to absorb wound fluids. Applications of this type are particularly required for highly secreting wounds, such as burn victims
  • Elastic bandages are also used in venous therapy. After surgical removal or obliteration of diseased vessels, an elastic bandage is wrapped around the diseased areas. The compresses close and protect the operating area.
  • An inventive development describes the use of an elastic bandage equipped on one side with an expandable hydrocolloid layer US Pat. 5,006,401. The compression is brought about by the elastic bandage. The hydrocolloid layer sticks to the skin, making it easier to apply the bandage and optimally caring for the wound. Skillful wrapping achieves the required compression through the elasticity of the bandage.
  • a wound dressing is known from DE 195 12 005 A1 which, as a wound dressing, generates mechanical pressure through strongly swelling absorber particles by absorbing wound exudate. The pressure generated therefore depends heavily on the presence of wound fluid.
  • DE 695 17 876 T2 describes a wound dressing which contains an elastically compressible moisture-absorbing foam which is designed as a layer separated from the wound dressing in order to prevent the drainage of to ease liquid secretions from the wound.
  • the foam is designed as a hydrophilic polyether polyurethane foam. Its compression and decompression properties are essentially static.
  • DE 692 29 940 T2 shows a foam for wound treatment that can be cured by the user during the application to produce a foam cushion.
  • the foam material is preferably used together with a plaster cast. Due to its use of synthetic resin, the cured foam has a remaining resilience, which gives the foam a certain flexibility. The application of this foam is difficult because the curing is done by adding moisture. Use on open wounds is therefore not possible. The hardening also requires a setting time of several minutes, so that this application is at best an alternative or supplement to a plaster cast.
  • earplugs formed from a polymer foam are known, which are used for hearing protection and which have a delayed reset speed for better adaptation to the auditory canals of the outer ear. This is between 1 and 60 seconds, with the material expanding from 60% to 40% compression. There is a slight pressure on the ear, on the one hand to adapt comfortably to the ear canal and on the other hand to achieve a higher noise reduction.
  • the invention has for its object to provide a simple wound dressing which is designed as a compression dressing, is easy to use and ensures an application-specific targeted compression and / or decompression effect.
  • the wound dressing is also intended to seal the wound permanently and germ-free and to stop bleeding by means of slight compression, so that subsequent bleeding can be prevented by appropriately dosed pressure, as well as circulatory disorders due to excessive pressure.
  • the pressure means is designed as an open or closed-pore foam material which is elastically reversibly deformable with a time delay and which is accommodated in the wound dressing between the wound swab and an outer covering layer projecting beyond the wound swab.
  • a wound dressing according to the invention enables high product benefits with only a small amount of material used.
  • the wound dressing is inexpensive to manufacture and can be used on the patient with a minimum of time.
  • the swab serves to absorb wound secretions, e.g. Blood. It can be made of different materials. Cotton fleece, plastic fabrics, knitted fabrics, polyurethane foam or hydrogel with superabsorbents are possible, which stick to dry skin but not on the wound.
  • the wound swab used in the invention is applied directly to the wound.
  • the invention can be used as a sterile or as a non-sterile variant.
  • the wound swab can also be omitted in a simplified form, e.g. if the function of the wound secretion is not necessary or is taken over by the pressure medium.
  • the pressure medium which is made, for example, of a polymer foam, is either positively or adhesively bonded to the wound swab. There are also any other joining techniques, such as ultrasonic welding, stapling or melting can be used.
  • the shape of the pressure means can be designed in any way three-dimensional, the surfaces can be adapted to that of the patient, for example. This way you meet the special requirements of a special body.
  • the invention describes a material which can be elastically and / or partially elastically deformed by manual compression and whose deformation is reversibly or partially reversibly reduced in time.
  • the material is particularly characterized by good processability, good handling, inexpensive to manufacture, ecological compatibility and sterilizability.
  • a material suitable for the purposes of the invention can be found in the aforementioned US Re 29,487. Foamed polymer foam with a density of 170 kg / m 3 is preferably used in the invention.
  • the decompression data mentioned in the cited document are not transferable to the invention.
  • the pressure medium is to be compressed as much as possible before application, for. B. to 20 - 25% of the initial volume.
  • the thickness should be about 2 mm in the compressed state, which results in a thickness in the decompressed state of about 8 mm.
  • the state of equilibrium should occur.
  • the state of equilibrium corresponds to a pressure of up to 100,000 pascals, preferably 1,000-30,000 pascals.
  • surface pressures of approx. 20,000 Pascal result.
  • a self-adhesive or non-adhesive carrier material is preferably used to fix the wound dressing in the patient's wound area.
  • This carrier material fixes the pressure element with the wound swab arri place of action. Furthermore, this should be inelastic in at least one direction, so that it can convert the force that develops during the delayed decompression of the pressure element into a slight pressure on the wound.
  • An example is a product with the brand name Fixomull, which has precisely these properties.
  • the delayed decompression of the wound dressing according to the invention allows the user enough time to stick the wound plaster properly onto a wound. After e.g. B. the blood draw 15 minutes are enough for wearing the patch.
  • a previously defined pressure can be set.
  • the defined pressure prevents e.g. B. bruises that can result from incorrect printing.
  • FIG. 2 shows an embodiment in plan view
  • Figure 3 shows an embodiment with outer packaging in plan view
  • Figure 4 is a fixation of cannulas and tubes
  • the wound dressing consists of a self-adhesive covering layer 1 for fixation on a wound.
  • This can e.g. be made of a fixomull carrier, but also consist of other suitable materials.
  • the pressure medium 2 is applied centrally to the cover layer 1.
  • This consists of a compressive foam, e.g. B. a polymer foam, but also other materials with similar properties are conceivable.
  • the pressure medium is equipped with a wound swab 3, the wound secretions such. B. should soak up blood.
  • the swab may e.g. B. consist of a fleece. However, other fabrics or materials with similar properties are also conceivable.
  • the wound dressing is preferably applied in the following order:
  • the wound dressing is removed from the packaging 4 (see also FIG. 3). Then the pressure medium together with the wound dressing is compressed in a maximum compressive manner. The delayed decompression leaves enough time to remove existing release papers 5 (see FIG. 2) in order to apply the wound dressing to the wound. Decompression then exerts a pre-defined pressure on the wound.
  • Figure 1 b shows the relieved condition of the wound dressing, in which the fixed cover layer exerts pressure on the wound via the pressure medium.
  • FIG. 2 shows a perspective view of the wound dressing with release paper 5 on the underside.
  • Figure 3 shows a packaged wound dressing.
  • the packaging is a vacuum packaging which on the one hand ensures sterility and on the other hand already produces a compressed state of the wound dressing, so that the wound dressing can be used immediately after opening the packaging. No release paper is required, nor is compression necessary before application if the application takes place before decompression begins. Such a wound dressing is therefore particularly suitable for emergency medicine.
  • FIG. 4 shows the use of the wound dressing for fixing cannulas and tubes 6, 7.
  • the wound swab can be dispensed with.
