Definitions
- the invention relates to a wound dressing which is suitable for stimulation treatment, in particular with electrostimulation devices.
- Electrostimulation devices and their use for wound treatment of chronic wounds, e.g. B. in venous leg ulcers or pressure ulcers, etc., using a dispersion electrode and a treatment electrode are known.
- the European patent application EP 0 557 562 describes a pre. direction and a method for nerve fiber and body tissue stimulation, e.g. B. to support wound healing.
- US Pat. No. 5,168,875 describes a strip electrode device and a method for its manufacture.
- the strip electrode consists of an electrically conductive layer, an electrically conductive adhesive layer and an electrically non-conductive insulating layer.
- the European patent application EP 0 504 715 relates to a wound treatment device. It consists of an electrically non-conductive layer which has an opening, an electrically conductive non-metallic agent and an essentially non-adhesive wound contact layer. Presentation of the invention. Task. Solution. benefits
- the object of the invention is to provide a wound dressing which is suitable for stimulation treatment, in particular for use with electrostimulation devices. It is preferably an object of the present invention to avoid the disadvantages of known energy-transmitting means which are used in stimulation treatments.
- the wound dressing consists of a combination of an energy transfer medium and a wound dressing agent. This combination makes it possible for the first time to combine the advantages of stimulation treatment with a suitable wound dressing or a suitable wound dressing and to provide a phase-appropriate wound dressing for every phase of wound healing.
- a material is selected as the wound dressing material that is particularly suitable for the wound dressing due to its physical properties, such as Foam or a hydrophilic material, or as a wound dressing material to choose a wound conditioning agent or a wound healing agent.
- the wound dressing consists of at least one wound dressing and an energy transfer medium and that the energy transfer medium has the wound dressing as a disk, mesh, film or plate-shaped body on at least one surface side.
- a Suitable energy transfer medium which must be designed with a shape suitable for the application of energy and must be provided with a suitable wound dressing agent at least on its side facing the wound floor, it is possible to carry out an optional physical, physiological and possibly chemical and biological wound care and at the same time by a suitable stimulation to further promote the wound healing process.
- the wound dressing consists of a wound dressing, into which an electrode is incorporated, and which additionally has a removable layer on at least one of its outer sides, which is removed when the wound dressing is applied to the wound.
- the teaching according to the invention is implemented by a basic structure of a new wound dressing, which consists in an energy transfer medium being embedded in a lower and an upper dressing material, preferably in the form of a hydroactive dressing.
- the lower layer of the dressing material is covered by a film that is removed before it is placed on the wound area.
- the upper layer of dressing material is also covered by a film that remains in the usual way to protect the wound dressing.
- the wound dressing according to the invention has the advantage that it is suitable for energy transfer, but can be used like a conventional wound dressing agent.
- One of the advantages of the wound dressing according to the invention is that, in particular in the case of a stimulation treatment, the dressing material which serves to protect or supply the wound area, in contrast to the known procedure, no longer has to be removed in order to transfer the energy transfer medium to the wound area to be treated to be able to muster. Accordingly, it is no longer necessary to apply new dressing material to the wound after stimulation treatment.
- wound dressing can be saved on dressing material. On the other hand, this makes it possible to reduce the treatment time by nursing staff. This represents a great advantage in the tense personnel and cost situation in the healthcare system.
- the reduction in the number of dressing changes that can be achieved by using a wound dressing according to the invention has the medical advantage that the healing process is not caused by mechanical irritation of the Wound area is disrupted when changing the dressing material and that the risk of infection is reduced by infrequent dressing changes.
- An electrode for electrostimulation, a magnetic plate or foil and / or a heating plate or foil can be used as the energy transmission medium.
- the selection is made depending on whether it is for example the care of large-area injury wounds or the care of chronic or other wounds, and which form of application corresponds to the phase-appropriate wound care.
- the core idea of the invention namely the combination of a suitable wound dressing and stimulation, is particularly valuable since the properties of the wound dressing agent can be used in a particularly suitable manner. It has proven to be particularly effective that the wound dressing is a hydroactive polymer or another material with hydrophilic properties or that the wound dressing is selected from the group consisting of hydrofiber materials, foams, hydrogels, hydrocolloids and alginates or a combination thereof.
- the formation of the energy transfer medium itself takes place in adaptation to the handling requirements and the type and shape of the Wound. It can advantageously be provided that the energy transmission medium is an energy-conducting film.
- the moisture absorption capacity can be optimally adjusted by the choice of providing the energy transfer medium with the wound dressing agent on only one side or using two layers of the wound dressing agent between which the energy transfer medium is embedded.
- wound dressing Another advantage of the wound dressing according to the invention is its ease of handling, which does not differ from conventional and known wound dressings.
- the wound dressing is protected from contamination by a peelable layer that can be easily removed from the corresponding area of the wound dressing before being applied to the wound surface.
- the layer On the side opposite to the wound area, the layer remains on the wound dressing and thus protects it in an advantageous manner.
- This layer is semi-permeable to enable water vapor to be drained off
- the wound dressing according to the invention is particularly advantageous since the duration of an energy transfer medium in the wound area can now be increased significantly because the energy transfer medium can now remain in the wound area with the same length of time as the wound dressing. Furthermore, the arrangement of the energy transfer medium in the wound area has now been considerably simplified. Furthermore, in the case of electrostimulation, the mode of action or the intensity of action of the pulsed electrostimulation has remained the same, or has even been improved, since the electrode can be closer to the skin area to be treated and the hydroactive dressing can also be better passed through. Ultimately, not only by extending the operating times of the individual energy transmission media, but also by improving the healing time as a whole economic effort is reduced, since in the optimal case a significantly smaller number of hydroactive dressings is required.
- FIG. 1 shows a purely schematic sectional illustration of an exemplary embodiment of a wound dressing according to the present invention
- FIG. 2 in a purely schematic plan view of another embodiment of a wound dressing according to the invention.
- the wound dressing 100 according to FIG. 1 is formed from the foils 10, 11, the wound dressing hydrogels 12, 13 and an energy transfer medium 14, which is located between the hydrogels 12 and 13 and is preferably designed as an electrode.
- the wound dressing can be any known material suitable for dressing purposes that has hydrophilic properties.
- a carrier material made of a natural or synthetic fiber is advantageous, which is either itself hydrophilic or / and is used in conjunction with special hydrophilic materials, such as hydrofiber materials.
- the wound dressing material is preferably distinguished by good electrical conductivity. Hydrogels and alginates are particularly preferred. It has proven to be particularly advantageous if further auxiliaries or medicinal substances, such as growth factors, are contained in or on the wound dressing. These can be chemical or biological substances such as enzymes, for example.
- the electrode which is designed as a carbon foil, metal foil or conductive silicone foil, can be liquid-permeable Mesh or as a film with small perforations, which ensures a uniform distribution of the moisture contained in the hydrophilic wound dressing and possible additives mentioned above.
- the configuration of the electrode as a carbon mesh, which is designed as a wickerwork or as a woven or knitted fabric, has proven to be particularly advantageous.
- a combination of electrode and wound dressing in the form of a fixed connection of both materials shows particularly good properties.
- the wound dressing 00 preferably has a flattened shape which has essentially two sides. Any other expedient and advantageous form is also conceivable, for. B. for special areas of the body that is essentially convex, concave, etc.
- the films 10 and 11 preferably consist of electrically non-conductive material, hydrophobic plastics, which are known to the person skilled in the art, being particularly suitable. Polyethylene, polypropylene or polyurethane films are particularly advantageous.
- the film can be coated with an adhesive, which ensures adhesion to the wound dressing means 12, 13. On the other hand, easy removal of the film 10 or 11 should be ensured. It is also conceivable that the film is attached by means of one or more seams and * is provided with a perforation or the like, on which it can be easily separated from the wound dressing.
- the wound dressing 100 preferably the electrode and particularly preferably the wound dressing, have good current conductivity.
- the material can be used, for example, with pulses of 2 to 12 microamps / cm 2 and a charge of 4 to 8, preferably 6 microcoulombs.
- the material preferably has a homogeneous conductivity, in particular over the electrode or wound dressing surface or essentially over the wound dressing.
- the wound dressing is structurally stable, in particular during storage and during its use, also during the application of electricity and particularly preferably while it remains on the wound.
