Definitions

• the present invention relates to a dressing intended to be applied to sensitive or painful areas or wounds in the process of healing or possibly around open wounds. More particularly, such a dressing comprises electrically conductive contacts which, by action on the human body, ' cause a remarkable attenuation of the sensation of pain.
• the causes of pain can be multiple: chronic or symptomatic.
• joint pain pain in the joints, sprains, sciatica, arthritis; muscle pain: low back pain; post-surgical and / or trauma pains, etc. More subtle, but just as real, one can also mention among the internal pains seasickness or car sickness as well as stress.
• Another mode of application of soft therapies is the permanent wearing of metallic objects directly against the skin such as copper bracelets. The effectiveness of such methods is still very controversial.
• the aim of the present invention is a dressing for therapeutic purposes by punctual stimulation of the self-defense mechanisms of the human body.
• the action of such a dressing should be as punctual as possible for better effectiveness.
• the presentation of the dressing must also allow the coverage of large painful areas.
• a medical dressing comprising a substantially flat flexible support at least covered on the underside with an electrically insulating adhesive layer and at least a couple of electrically conductive contacts, hereinafter referred to as “conductive contacts “or simply by” contacts “, made of two different metals or alloys, hereinafter simply designated by” metals “for the simplicity of the description.
• conductive contacts are located in the thickness of the adhesive layer so that their lower faces are flush with the outside of the adhesive layer, and are connected to each other by an electrical connection taken between the adhesive layer and the support.
• lower face is intended to denote the face on the skin side, coming into contact directly with it or through a material or an appropriate material not opposing electrical contact, such as creams or ointments for example.
• the dressing may be in individual form comprising one or more pairs of conductive contacts.
• It can also be in the form of a continuous strip filled with a series of transverse pairs of contacts, for example regularly separated, or also in the form of a continuous strip furnished with a pair of contacts in substantially parallel strips. .
• the conductive contacts are circular or in strips, of diameter or width substantially equal to a quarter of the width of the strip, and the transverse pairs of contacts are spaced from each other by a distance substantially equal to one third. the width of the ribbon.
• the conductive contacts can be made of materials such as gold, silver, copper, zinc, aluminum or stainless steel, provided that they are combined in pairs of two distinct metals or alloys having electromotive forces or electrochemical potentials, and / or sufficiently different resistivities.
• copper has a more positive potential than zinc and their association by couple generates a potential difference which is responsible for the desired effect.
• gold associated with silver, gold with aluminum, copper to zinc, silver to copper, gold to bronze or even bronze to aluminum preferably the gold / aluminum and bronze / aluminum pairs for reasons of implementation in the form of metal strips, braids or braids and comfort of use.
• the desired effect could, it seems, be analyzed in theoretical terms by the migration of electrical charges, ions and / or electrons, by a simple electrical rebalancing consecutive to a modification of the potentials present, by the creation of charges electrostatic, or by the propagation of a depolarization wave at the cellular level.
• the main action sought is to "lift" the energy barriers thereby recovering a functional energy circulation in relation to all the body's defenses. This action is obtained by energetic topographic stimulation, in particular on different areas or acupuncture points.
• Electrodes In the rest of the presentation, we will keep the more general term “contacts” and we will avoid using the term “electrodes” which would however seem very appropriate. This term However, electrodes have a very precise meaning in physics and their use would risk harming the interpretation and explanation of the phenomena observed.
• FIG. 1 is a sectional and perspective view from above of a dressing in a first embodiment
• FIG. 2 is a sectional perspective view from below of a dressing in a second embodiment.
• the dressing is in the form of a continuous tape comprising a first layer 100 of support and a second lower layer 110 of adhesive.
• the layer 100 is preferably made of a flexible planar material such as plastic, textile or felt, provided that this material can be introduced in a sterile manner.
• the adhesive layer must firstly be non-toxic and have an adhesion coefficient such that the dressing can remain in place as desired but that it can be removed without difficulty when necessary.
• this bandage is provided with conductive contacts 120 and 140 connected in pairs by bridges or electrical connections 130. These contacts are preferably in the form of thick circular patches identical to that of the adhesive layer 110 so that their lower surfaces are flush with the dressing.
• the pairs of contacts are arranged transversely to the strip in a series of constant spacings i.
• the diameter of each contact is substantially equal to a quarter of the width 1 and the spacing i between each pair of contacts is substantially equal to one third of this width 1.
• the electrical connection 130 can be made of a metal identical to that of one of the contacts or be a third more common metal such as copper. This connection can be welded to the two contacts respectively or have only an intermittent electrical connection, that is to say by pulses, for more specific therapeutic effects.
• FIG. 2 Another embodiment of the dressing according to the invention is shown in FIG. 2, where, for the sake of clarity, the active part intended to come into contact with the skin is shown upwards, that is to say that is to say contrary to the representation of FIG. 1.
• the dressing is also in the form of a continuous ribbon comprising a first support layer 200 and a layer 205 of adhesive.
• the conductive contacts are made in the form of two overlapping metal strips 210 and 230, so as to provide electrical continuity.
• the strip 210 is a gold leaf, for example 4) m thick, while the other strip 230 is an aluminum sheet.
• an insulating strip 240 is fixed, so that the finished dressing has two conductive strips making contact, substantially parallel to each other and separated by an insulating strip.
• This type of dressing is rather intended to treat painful areas, or to be placed on either side of a wound in the process of healing.
• the dressing is in the form of a patch ("patch") made in the form of two concentric metallic patches placed one on the other and the second of which has a diameter greater than the first one.
• an insulating strip is fixed at the junction of the two metals so that the finished dressing has a central conductive pad making contact, separated by an insulating strip from an outer conductive ring.
• the two metals are in the form of braces or braids in the center of which the insulating band has been placed.
• the dressing according to the invention can be used in the treatment of pain, particularly in the treatment of stubborn or diffuse pain rebellious to any alopathic treatment, or also as stimulating agents for wound healing.
• a .43-year-old male patient was treated by applying a bandage in accordance with FIG. 2 made with a gold / aluminum conductive couple, each evening on either side of the spine on the painful region Lx, L 2 , L 3 and this for three evenings in a row.
• Example 1B Treatment of ligament pain
• Example 2A A 5 to 7 cm long dressing, like that of Example 1A., Is placed directly on the ligament or in a sling around the external malleolus, for example in the case of stretching the LLE (tibiotarsal).
