Description

Technical Field

[0001] This invention relates to the field of plaster technology for application to the skin surface, and more particularly to a far-infrared electrotherapy device. Background Technology

[0002] Far-infrared rays are a type of electromagnetic wave with a wavelength of 3–1000 micrometers, capable of penetrating the skin's surface and acting on deeper tissues. Far-infrared patches contain materials that emit far-infrared rays, such as ceramic powder and magnetic materials, which can continuously release far-infrared rays when stimulated by body temperature.

[0003] Existing far-infrared patches combine far-infrared technology with traditional patch therapy, typically consisting of far-infrared ceramic powder, medical pressure-sensitive adhesive, non-woven fabric, and a release film. In use, the release film is removed, and the patch is applied to the painful area of ​​skin. The ceramic powder, stimulated by body temperature, continuously emits far-infrared rays, achieving effects such as pain relief and improved local blood circulation. However, these far-infrared patches have a slow onset of action, requiring a certain amount of time to accumulate the thermal effect. Their effect is passive and cannot directly stimulate neuromuscular nerves. Due to their limited efficacy, they are generally used as an adjunct to other forms of physical therapy.

[0004] A Chinese invention patent application (CN201910787421.6) entitled "A Far-Infrared Plaster and Its Preparation Method" discloses a far-infrared plaster comprising the following raw materials in parts by weight: 90-100 parts rubber plaster, 0.03-0.06 parts far-infrared ceramic powder, 0.002-0.005 parts borneol, 0.002-0.005 parts ginger powder, and 0.002-0.005 parts mugwort powder. This invention solves the problems of poor user experience, slow onset of action, incomplete treatment, and easy recurrence associated with existing far-infrared plasters. However, the onset speed of the plaster prepared by this method is still not ideal, therefore the structure of the plaster needs further improvement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a far-infrared electrotherapy device that adds pulse electrotherapy function to the existing far-infrared radiation function, and has a fast and good effect on neuromuscular stimulation, in view of the above-mentioned existing technology.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: This far-infrared electrotherapy device is characterized by comprising a first protective layer, a substrate layer capable of emitting far-infrared radiation, a first connecting layer, an insulating layer, a conductive connector capable of being connected to an external power source to stimulate the substrate layer to emit far-infrared radiation, a second connecting layer, and a second protective layer. The first protective layer covers the surface of the substrate layer. The other side of the substrate layer is connected to one side of the insulating layer through the first connecting layer. The other side of the insulating layer is connected to the second protective layer through the second connecting layer. The second connecting layer is an adhesive structure that can adhere to the skin and conduct electricity. The second protective layer can be peeled off and adhered to the second connecting layer. The conductive connector passes through the first protective layer and the insulating layer and is connected to the substrate layer and the second connecting layer.

[0007] As an improvement, the substrate layer is preferably a sheet structure made of far-infrared radiating material and medical pressure-sensitive adhesive.

[0008] In a further improvement, the far-infrared radiation material used in the substrate layer can preferably be specially processed ceramic powder or natural minerals, wherein the natural minerals are one or more of tourmaline, titanium dioxide, zirconium dioxide, silicon carbide, and alumina.

[0009] As an improvement, the first protective layer may preferably be a composite film made of non-woven fabric, elastic fabric or PET film and aluminum foil.

[0010] As an improvement, the first connecting layer can preferably be a conductive film. The conductive film can more evenly transfer the current on the conductive connector to the substrate layer, fully stimulating the radiation effect of the far-infrared material.

[0011] As an improvement, the insulating layer can preferably be PET, PU, ​​or medical-grade foam. This provides good insulation.

[0012] As an improvement, the second connecting layer can preferably be a conductive gel that can adhere to the skin. It has conductive properties and is easy to apply to the skin.

[0013] As an improvement, the second protective layer can preferably be a release film. This makes it easy to peel off the second protective layer during use, thus simplifying the process.

[0014] As an improvement, the conductive connector is preferably a metal clip that can be directly plugged into a pulse generator capable of generating pulse current. The metal clip includes a positive clip and a negative clip. The metal clip can be directly plugged into the pulse generator's interface, facilitating the connection and disconnection of the pulse generator and the conductive connector.

[0015] As an improvement, a gasket that enhances insulation is preferably sandwiched between the first connecting layer and the insulating layer, with the conductive connector passing through the corresponding gasket. Adding an air gap between the first connecting layer and the insulating layer further enhances the insulation effect.

[0016] Compared with the prior art, the advantages of this invention are as follows: the substrate layer can emit far-infrared radiation, and under the stimulation of human body temperature, it continuously emits far-infrared rays to achieve the effects of relieving pain and improving local blood circulation; the conductive connector passes through the first protective layer and the insulating layer and is connected to the substrate layer and the second connecting layer. The conductive connector can be connected to an external power source, which serves as a conductive structure to stimulate the substrate layer to emit far-infrared rays more quickly, and also serves as a contact point for the pulse host to contact the skin, transmitting pulsed microcurrents to the skin to achieve microcurrent electrotherapy for the skin. The combination of far-infrared therapy and pulsed electrotherapy enhances the therapeutic effect by combining the immediate effect of electrotherapy with the continuous warmth of far-infrared rays.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 7As shown, the far-infrared electrotherapy device of this embodiment includes a first protective layer 1, a substrate layer 2 that emits far-infrared radiation, a first connecting layer 3, an insulating layer 4, a conductive connector 5 that can be connected to an external power source to stimulate the substrate layer 2 to emit far-infrared radiation, a second connecting layer 6, and a second protective layer 7. The first protective layer 1 covers the surface of the substrate layer 2. The other side of the substrate layer 2 is connected to one side of the insulating layer 4 through the first connecting layer 3. The other side of the insulating layer 4 is connected to the second protective layer 7 through the second connecting layer 6. The second connecting layer 6 is an adhesive structure that can be adhered to the skin and is conductive. The second protective layer 7 can be peeled off and adhered to the second connecting layer 6. The conductive connector 5 passes through the first protective layer 1 and the insulating layer 4 and is connected to the substrate layer 2 and the second connecting layer 6.

[0026] Substrate layer 2 is a sheet-like structure made of far-infrared radiating material and medical pressure-sensitive adhesive. The far-infrared radiating material used in substrate layer 2 is specially processed ceramic powder or natural minerals. The natural minerals are one or more of tourmaline, titanium dioxide, zirconium dioxide, silicon carbide, and alumina. Medical pressure-sensitive adhesive is a common material and is well known to those skilled in the art. The special processing methods for ceramic powder or natural minerals are known technologies and will not be described in detail here.

[0027] The first protective layer 1 is a composite film made of non-woven fabric, elastic fabric, or PET film and aluminum foil. The first connecting layer 3 is a conductive film. Conductive adhesive can be applied to the surface of the conductive film to bond it to the substrate layer and the insulating layer. Alternatively, the conductive film can be left unattached, in which case it is sandwiched between the substrate layer 2 and the insulating layer 4. The conductive connector 5 connects the substrate layer 2, the conductive film, and the insulating layer 4 in series. A gasket 8 can be sandwiched between the first connecting layer 3 and the insulating layer 4 to enhance insulation, and the conductive connector 5 passes through the corresponding gasket 8.

[0028] Insulation layer 4 is made of PET, PU or medical-grade foam.

[0029] The second connecting layer 6 is a conductive gel that can adhere to the skin. The second connecting layer 6 can use a second conductive film as the base material, with the conductive gel adhering to the second conductive film, facilitating installation and fabrication.

[0030] The second protective layer 7 is a release film. Release films are a known technology; when using them, the release film needs to be peeled off to allow the conductive gel to adhere to the skin.

[0031] The conductive connector 5 is a metal clip that can be directly plugged into a pulse generator capable of generating pulse current. The metal clip includes a positive clip and a negative clip. The specific structure of the pulse generator and the circuit structure used in the pulse generator are known technologies and will not be described in detail here.

[0032] Working principle: The far-infrared electrotherapy device includes a backing (i.e., the first protective layer), a substrate layer, a conductive and adhesive layer, an insulating layer, a conductive connector, and a protective layer (i.e., the second protective layer).

[0033] The backing is a composite film made of non-woven fabric, elastic fabric, or PET film and aluminum foil; the substrate layer consists of far-infrared radiating material and medical pressure-sensitive adhesive. The far-infrared radiating material is specially processed ceramic powder or natural minerals, such as tourmaline, titanium dioxide, zirconium dioxide, silicon carbide, and alumina. The conductive and adhesive layer is a conductive film + conductive gel. The insulating layer is PET, PU, ​​or medical-grade foam; the conductive connectors are metal fasteners or conductive posts; the protective layer is a release film.

[0034] The first layer is a backing, which can prevent the internal components from evaporating or getting damp, and gives the substrate layer a certain strength, making it easy to apply.

[0035] The second substrate, far-infrared radiation material, is used to generate far-infrared rays. Medical pressure-sensitive adhesive binds the far-infrared radiation material together and makes it easy to adhere to the skin.

[0036] The third and fifth layers are conductive and adhesive layers. The conductive film is used to receive the current from the conductive connector and conduct it to the conductive gel. The conductive gel plays the role of conducting electricity and adhesion. The current through the conductive film forms a uniform current path on the conductive gel and adheres to the skin surface. The current will penetrate the skin surface and directly stimulate the neuromuscular system.

[0037] The fourth insulating layer allows current to pass through the conductive gel layer without leakage.

[0038] The conductive connector connects the first, second, third, and fifth layers and is used to connect the pulse generator, i.e., the pulse current generator, and conduct the current to the conductive gel.

[0039] A protective layer covers the surface of the conductive and adhesive layers to prevent the conductive gel from drying out or becoming contaminated.

[0040] To use, peel off the protective layer, stick it to the skin surface, install the pulse unit on the backing through the conductive connector, turn on the power of the pulse unit, and adjust it to the appropriate electrotherapy level to enjoy the dual treatment of far-infrared and electrotherapy.

[0041] Existing far-infrared therapy is slow to take effect and cannot directly stimulate the painful area. This invention combines far-infrared therapy with pulsed electrotherapy, enhancing the therapeutic effect by combining the immediate effect of electrotherapy with the continuous warmth of far-infrared radiation.
