Description

Technology Field

[0001] The present invention relates to a micro-electrical stimulation scar band, and more specifically, to a micro-electrical stimulation scar band that treats a wound or scar by applying electrical stimulation to a lesion area such as a wound or scar without an external power source. Background Technology

[0002] Microcurrent refers to a very weak current that takes the form most similar to the bioelectricity flowing in the human body. It has been proven that applying microelectric stimulation of a similar intensity to this bioelectricity (e.g., current of about 1000 μA or less) has effects such as wrinkle improvement, promotion of wound and fracture healing, alleviation of muscle fatigue, reduction of inflammation, improved blood circulation, and reduction of abdominal fat.

[0003] However, these conventional microelectric stimulation devices have complex configurations and limitations in miniaturization, as they require connection to an external power source or a separate energy source (power source) to drive devices such as rechargeable batteries or energy harvesters utilizing triboelectricity, and require electrical connection to the energy source. Furthermore, they have problems such as poor portability, making them difficult to wear (use) during daily life, and low energy efficiency due to the aforementioned dielectric loss during operation.

[0004] A device that applies electrical stimulation without a separate power source has been proposed, in which an oxidizing metal is incorporated into a hydrocolloid to generate an internal voltage in the hydrocolloid using electrons produced by the oxidation reaction of the metal. However, since the hydrocolloid itself has a certain conductivity due to moisture, the generated electrons are easily lost to the outside of the hydrocolloid, and there is a problem in that it is difficult to continuously generate electrons due to the metal oxide film formed by oxidation. Therefore, there is a need for the development of a technology that can solve the aforementioned problems and continuously provide electrical stimulation to lesion areas such as wounds or scars. Prior art literature

[0005] Patent Document 1. Korean Published Patent Application No. 20-2006-0012979 The problem to be solved

[0006] The present invention has been devised in consideration of the above-mentioned problems, and the objective of the present invention is to provide a micro-electrical stimulation scar band capable of continuously providing micro-electrical stimulation to a lesion area without an external power source. means of solving the problem

[0008] To achieve the above objective, the present invention provides a micro-electrical stimulation scar band characterized by comprising: an upper mat; a lower mat coupled to the lower portion of the upper mat; a pair of recessed grooves formed spaced apart to accommodate a wire, formed to a predetermined depth along the perimeter of the outer surface of the lower mat; the wire being wound around the lower mat along the recessed groove formed along the perimeter of the outer surface of the lower mat; the wire being fixed by the recessed groove; and the wire forming a single closed loop.

[0009] The lower surface of the upper mat may further include a first adhesive layer.

[0010] The average thickness of the above lower mat may be 0.001 to 0.5 cm.

[0011] The above-mentioned lower mat is composed of at least one layer, and may further include a waterproof layer between the layers.

[0012] A second adhesive layer may be formed on the lower surface of the above-mentioned lower mat and attached to the user's lesion area.

[0013] The thickness of the above wire may be 0.001 to 1 mm.

[0014] The distance between the above wires may be 3 to 5 times the thickness of the above wires. Effects of the invention

[0015] According to the present invention, by continuously providing microelectric stimulation to a lesion site, such as a wound or scar, without an external power source, it is possible to achieve the effect of promoting and activating wound healing, improving scars, and regenerating them into normal skin.

[0016] The micro-electrical stimulation scar band of the present invention can prevent unnecessary damage by preventing deformation of the end shape, minimizes discomfort and shock absorption due to its flexible material, and provides consistent micro-electrical stimulation while having excellent efficiency through direct connection, so it can be used to treat wounds or scars by replacing conventional expensive foam dressings. Brief explanation of the drawing

[0017] FIG. 1 is a perspective view of a micro-electrical stimulation scar band according to a first embodiment of the present invention. FIG. 2 is a diagram illustrating an example of using the micro-electrical stimulation scar band of the present invention on a user's lesion site. Figure 3 shows a micro-electrical stimulation scar band manufactured with a structure as shown in Figure 1 by wrapping a conductive thread (silver-coated synthetic fiber thread) as a wire around a 0.5 cm lower mat consisting of synthetic fiber fabric (bandage)-silicone-synthetic fiber fabric (bandage), and then laminating a polyurethane (PU) upper mat coated with adhesive, and measuring the magnitude of the electrical stimulation generated by the micro-electrical stimulation scar band while it is attached with one end of the conductive thread touching the arm. Specific details for implementing the invention

[0018] Below, various aspects and embodiments of the present invention will be examined in more detail.

[0019] The objects, other objects, features, and advantages of the present invention will be easily understood through the following preferred embodiments associated with the accompanying drawings. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, the embodiments introduced herein are provided to ensure that the disclosed content is thorough and complete and that the spirit of the invention is sufficiently conveyed to a person skilled in the art.

[0020] In this specification, terms such as “comprising” or “having” are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should not be understood as precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0021] In this specification, where a range is described for a variable, it will be understood that the variable includes all values ​​within the described range, including the described endpoints of the range. For example, the range “5 to 10” will be understood to include not only the values ​​5, 6, 7, 8, 9, and 10, but also any sub-ranges such as 6 to 10, 7 to 10, 6 to 9, 7 to 9, etc., and any values ​​between integers valid for the category of the described range, such as 5.5, 6.5, 7.5, 5.5 to 8.5, and 6.5 to 9. Also, for example, the range “10% to 30%” will be understood to include all integers including values ​​such as 10%, 11%, 12%, 13%, etc. and up to 30%, as well as any sub-range such as 10% to 15%, 12% to 18%, 20% to 30%, etc., and any value between valid integers within the stated range category such as 10.5%, 15.5%, 25.5%, etc.

[0022] Animals, including humans, contain large amounts of water within their bodies. Objects containing such large amounts of water can act as a medium capable of transmitting or propagating minute energy with minimal loss through dielectric phenomena. In practice, contact between animals and objects, between objects equipped with contact with animals, or between animals themselves causes surface electrification. As the electrical equilibrium state shifts due to changes in contact during the process, an alternating current electric field is generated at the contact surface (e.g., electrostatic phenomena). This is called the triboelectric effect, and as a result, minute extrinsic alternating current (AC) and dielectric polarization are generated through the large amount of fluid present within the body, thereby producing a minute extrinsic alternating current electric field.

[0023] We have developed a microcurrent stimulation band for scar treatment capable of generating microelectric stimulation by utilizing the micro extrinsic alternating current inevitably generated in animals, including humans, due to the triboelectric effect, and the micro extrinsic alternating electric field propagated / transmitted within the animal through dielectric polarization caused by moisture contained in the animal, thereby completing the present invention.

[0024] The micro-electric stimulation scar band according to the present invention generates micro-electric stimulation by utilizing triboelectricity generated by contact electrification (or triboelectrification) that inevitably occurs within the body. It can provide micro-electric stimulation to a desired lesion site without a separate power source or energy generation means. Below, the micro-electric stimulation scar band according to the present invention will be described in detail with reference to the attached drawings.

[0025] FIG. 1 is a perspective view of a micro-electrical stimulation scar band according to one embodiment of the present invention. Referring to FIG. 1, the micro-electrical stimulation scar band (10) according to the present invention may be a micro-electrical stimulation scar band characterized by having, from the outside, an upper mat (100); a lower mat (200) coupled to the lower part of the upper mat (100); and a pair of wires (300) spaced apart and wound along the outer circumference of the lower mat (200), wherein each of the wires (300) forms a closed loop.

[0026] The upper mat (100) and lower mat (200) can improve operational reliability and stability by fundamentally blocking the transfer of electric charge to the outside. In particular, the lower mat (200) prevents direct contact between wires wound along the circumference of the lower mat. For example, the wires located on the lower surface of the lower mat are positioned to come into contact with the user's lesion area by the lower mat (200), while the wires located on the upper surface of the lower mat are positioned so as not to come into contact with the skin. Due to this structure, when the micro-electric stimulation scar band is attached to the lesion area, the wires located on the lower surface of the lower mat (200) that come into direct contact with the lesion area may be input (applied) with a micro alternating electric field propagated through dielectric polarization within the user, and a potential difference may be formed within a single wire by this input of a micro alternating electric field.

[0027] More specifically, as the wire located on the lower surface of the lower mat (200) comes into contact with an alternating electric field that moves due to dielectric polarization through contact with the lesion site, a complementary charge capable of canceling out this dielectric polarization (alternating electric field) is formed, and the wire located on the upper surface of the lower mat (200) acts as a pool of free charges (free electrons) similar to ground, thereby supplying the complementary charge and forming a potential difference. Due to this potential difference, an alternating current is generated in the wire (300), so that electrical micro-stimulation can be applied to the lesion site without an external power source.

[0028] Accordingly, the area of ​​the upper mat (100) is not particularly limited, but may have an area equal to or larger than the area of ​​the lower mat (200). Among these, it is most preferable for the upper mat (100) to have an area larger than the area of ​​the lower mat (200). In this case, the lower mat (200) is attached to the user's lesion area by the first adhesive layer (110) of the upper mat (100), thereby allowing the second adhesive layer of the lower mat (200) to be omitted, making it easy to attach to the lesion area.

[0029] In addition, when the upper mat (100) is attached to a lesion site such as a wound or scar on the body, if the upper mat (100) becomes contaminated by exudate, bleeding, oil, or sweat caused by the skin or wound, the first adhesive layer (110) of the contaminated upper mat (100) can be detached from the skin, and a new upper mat (100) can be combined with the existing lower mat (200) and reattached to the skin, allowing for easy replacement at any time. Since the condition of the lesion site can be checked through replacement, problems such as secondary contamination or eczema can be prevented.

[0030] The upper mat (100) above can be made of various types of synthetic resin film materials such as polyurethane (PU), polyethylene (PE), or polypropylene (PP).

[0031] The first adhesive layer (110) is a layer in which an adhesive is applied to the lower surface of the upper mat (100), and the adhesive may be applied to all or part of the lower surface of the upper mat (100).

[0032] The upper mat (100) according to the present invention may have a larger area than the lower mat (200) of the micro-electrical stimulation scar band (10) as shown in FIG. 2, and in this case, a first adhesive layer may be applied to the surface where the upper mat (100) and the lesion site come into contact in order to adhere the lower mat (200) to the lesion site.

[0033] The adhesive used in the present invention is an adhesive harmless to the human body, and while it is preferable to use a polyurethane-based adhesive, it is not specifically limited thereto; any adhesive having physical properties equivalent to or better than those of the said adhesive may be used.

[0034] The lower mat (200) is not particularly limited to any insulating material that does not induce skin irritation when in contact with the skin. Specifically, it is preferable that the lower mat (200) be an insulating material that can be attached to a lesion area such as a scar or wound. It is also preferable to select and use non-woven fabric, natural fiber fabric, or synthetic fiber fabric as the material used. In addition to the materials listed above, any material harmless to the human body that has release properties allowing it to be easily separated when bonded to the upper mat (100) of a synthetic resin film may be used.

[0035] The thickness of the upper mat (100) is not particularly limited thereto, but the average thickness of the lower mat (200) may be 0.001 to 0.5 cm, and more preferably 0.05 to 0.5 cm. If the thickness exceeds the range of 0.5 cm, it may cause discomfort to the wearer when wearing clothing or when body movement occurs while in contact with the skin. In addition, if the thickness is less than the range of 0.05 cm, physical force may be concentrated on the wires provided in the lower mat (200) and deform, and a problem may occur in which some of the wires are not electrically separated from the remaining parts in contact with the skin and remain connected, resulting in no micro-stimulation.

[0036] By checking the degree of contamination of the upper mat (100), a hemostatic effect can be obtained by using multiple layers of lower mats (200) as a compression member to wrap around and compress the lesion area, thereby blocking blood flow.

[0037] The lower surface of the lower mat (200) comes into contact with the user's lesion area, and generates micro-electric stimulation to the lesion area by utilizing the electric charge phenomenon inevitably accompanying the user's surface by this contact.

[0038] The lower surface of the lower mat (200) may further include a second adhesive layer (210). The second adhesive layer (210) is a layer to which an adhesive is applied so that the lower mat (200) and the user's lesion area are bonded, and the second adhesive layer may be applied to the surface where the lower mat (200) and the lesion area come into contact. The adhesive used in the present invention is an adhesive that is harmless to the human body, and it is preferable to use a polyurethane-based adhesive, but it is not specifically limited thereto, and any adhesive having physical properties equal to or better than the adhesive may be used.

[0039] The above-mentioned lesion site refers to a tissue site where a wound, scar, or internal or external defect has occurred. The above-mentioned wound may include burns, incisional and excisional wounds, ulcers, traumatic wounds, and chronic non-healing wounds.

[0040] Additionally, the scar may refer to fibrous tissue that replaces normal tissue destroyed by injury or disease. Generally, damage to the outer layer of the skin heals by reconstructing the tissue, and in such cases, scar formation may be minimal. However, if a thick layer of tissue beneath the skin is damaged, skin reconstruction becomes complicated, and a scar is induced as collagen fibers accumulate. Specifically, the scar may be a hyperplastic scar, a keloid scar, an atrophic scar, or a stretching mark.

[0041] When tissue is damaged, the damaged tissue becomes abnormally charged with a current different from the current originally charged on the cell membrane, which is called the injured current (wound current). If the injured current in the damaged tissue is restored to the same state as that in normal cells, the flow of ions occurs smoothly, thereby promoting cell repair. The micro-electrical stimulation scar band (10) according to the present invention is based on this principle. By providing micro-electrical stimulation using an in vivo energy source without an external power source to a lesion area where damaged or abnormal cells exist, the cells are activated to return to a normal state, thereby allowing the wound to heal early and preventing scar formation, and providing the effect of regenerating scars.

[0042] The lower mat (200) is preferably composed of at least one layer, and may further include a waterproof layer (220) between the layers.

[0043] The above waterproof layer (220) may be included in the layer difference constituting the lower mat (200). For example, the lower mat (200) is formed with one or more layers of a first insulating layer from the top to the middle part of the lower mat (200), one or more layers of a second insulating layer from the bottom of the first insulating layer to the bottom of the lower mat (200), and only one or more layers of a waterproof layer (220) are disposed between the first and second insulating layers of the lower mat (200).

[0044] The above waterproof layer (220) may be formed as one layer or more than one layer, and preferably may be formed as one to two double layers.

[0045] The above waterproof layer (220) is made of a waterproof and elastic material such as vinyl, rubber, silicone, or Parafilm, so that contaminants or sweat from the affected area are not absorbed into the lower mat, thereby accurately dividing the wire (300) into a part that contacts the skin and a part that does not contact the skin, so that they do not substantially affect each other, and thus high electrical stimulation can be induced in a small area.

[0046] The method of combining the first and second insulating layers and the waterproof layer is not particularly limited as long as it is a lamination method widely known in the art, but preferably, it may be manufactured by laminating, applying, or positioning the waterproof layer between the first and second insulating layers and then compressing them together.

[0047] It is more preferable to select materials having different resistance values ​​for the first insulating layer of the lower mat (200) and the first adhesive layer (110) of the upper mat (100). Specifically, it is most preferable that the resistance value of the first adhesive layer (110) of the upper mat (100) is lower than that of the first insulating layer of the lower mat (200). In this case, the problem of the value changing due to the user's electrical resistance can be resolved, and there is an effect of providing stable and uniform micro-stimulation. As a result, the problem of inconsistent electrical stimulation being applied to a lesion area that is more sensitive than normal skin can be resolved, and even if deformation occurs due to exudates from the wound or the user's movement, this can be compensated for, thereby improving the problem of poor micro-stimulation characteristics or reduced performance.

[0048] To adjust the electrical resistance value of the first adhesive layer (110) of the upper mat (100), the polyurethane-based adhesive may further include a filler, for example, conductive carbon black, carbon fiber, silicate, dolomite, and aluminum hydroxide may be further included as fillers, but are not particularly limited thereto.

[0049] The above wires (300) may be a spaced-apart pair wrapping around the lower mat (200) along the outer circumference of the lower mat (200).

[0050] If the length of the lower mat (200) increases, additional wires can be placed in proportion to the length of the above wire (300).

[0051] The above wires (300) are arranged so that the wires located on the opposite side of the lower mat (200) do not come into contact with each other, and thus have a potential difference due to the electric field generated in the human body. As previously explained in the lower mat structure, to explain it in more detail again, the human body, which is composed of 70 to 80% polar molecules (water), undergoes a dielectric phenomenon due to triboelectricity, and an electric field is formed as an electric current flows within the body. Due to the electric field generated in the human body, a potential difference occurs between the two electrodes, and an alternating current is generated between the two electrodes, thereby forming a second electric field. As a result, a microcurrent is transmitted to the lesion area to which the micro-electric stimulation scar band (10) of the present invention is attached, thereby stimulating it.

[0052] In the present invention, the wires (300) are arranged such that a pair of wires are spaced apart, which may mean that the wires are arranged parallel to each other. More specifically, the plurality of wires (300) may be spaced apart from each other and arranged along the circumferential direction of the lower mat (200). For example, the plurality of wires (300) may be wound and arranged along a first direction, which is the length direction of the lower mat (200). At this time, the first wire (300a) may be arranged parallel to the second wire (300b). At this time, the wires (300a, 300b) may be arranged in such a way that they do not cross or overlap each other. By arranging the plurality of wires (300) so that they do not cross or overlap each other, a uniform electric field can be induced.

[0053] As each of the above wires (300) forms a closed loop, they can provide microelectric stimulation to the lesion site due to a potential difference caused by micro alternating current electric field pressure, thereby providing higher and more uniform microstimulation than a wire with a planar shape of the same area, and the manufacturing process is simplified and simple, making it easy to mass-produce.

[0054] The above wire (300) may be a conductive thread, and the conductive thread may be a metal wire composed of a conductive material such as gold, silver, stainless steel, copper, etc., or a natural fiber or artificial regenerated fiber coated with a conductive material such as gold, silver, stainless steel, copper, etc.

[0055] The thickness of the above wire (300) is preferably 0.001 to 1 mm, and it is desirable that the above range is less uncomfortable when attaching the scar band (10) and is lighter and smaller in shape, and it is also desirable to have uniform electrical performance and shape stability.

[0056] The distance between the above wires (300) is preferably 1.5 to 5 times the thickness of the wires, and the distance between the wires (L) refers to the distance between a pair of wires, and can be appropriately selected considering the shape or size of the area where electrical stimulation is required, but it is more preferable to be 1.5 to 5 times to provide the same electrical stimulation to the same area.

[0057] When the upper mat (100) and the lower mat (200) are both provided with a first and second adhesive layer, and the wire (300) is in the form of a pair of spaced-apart closed loops, and the wire thickness is 0.001 to 1 mm, and the distance between wires is 1.5 to 5 times the thickness, all conditions are satisfied, so that deformation of the end shape can be prevented to prevent unnecessary damage, and shock absorption and discomfort can be minimized due to the flexible material.

[0058] The above-mentioned micro-electrical stimulation scar band (10) is characterized by being configured to generate a microcurrent when attached to the body.

[0059] The above-mentioned micro-electrical stimulation scar band (10) uses an electric field generated from the human body as an energy source without external power, and by applying a constant electric stimulation to a local lesion area in contact, it can provide a large amount of triboelectricity to the subject compared to a simple wound dressing, thereby enhancing the alleviation and treatment effects on scars and wounds caused by electric stimulation.

[0060] According to another embodiment of the present invention, the micro-electrical stimulation scar band (10) may have a structure further comprising a release liner (400).

[0061] The above release liner (400) may be placed on the lower surface of the first adhesive layer (110) of the upper mat (100) or the second adhesive layer (210) of the lower mat (200). The release liner is removed upon use to fix the adhesive surface of the adhesive layer to the wound area. The release liner is not particularly limited, but generally, a known release liner in the form of a silicone release agent applied on a polypropylene, polyester, or polyethylene polymer film may be used.

[0062] FIG. 2 is a diagram for explaining the principle of treating wounds or scars using microcurrents by attaching a micro-electric stimulation scar band (10) to a user's skin lesion area. According to FIG. 2, when a user attaches the micro-electric stimulation scar band (10) around the affected area (20) to treat a wound or scar, the wire (300) wrapped around the lower mat (200) forms a closed circuit together with the human body.

[0063] When a closed circuit is formed in this way, an alternating current (AC) generated by triboelectricity within the body outputs a micro-stimulation similar to bioelectricity through a wire (300) and is transmitted to a wound or scar area, thereby activating damaged or abnormal cells so that they can return to a normal state through the micro-stimulation, and at the same time, by stimulating the wound area, the wound area heals early and prevents scar formation.

[0064] The micro-electrical stimulation scar band (10) according to the present invention does not require a separate secondary dressing for fixation to the wound area, and in cases such as contamination or checking the progression of the lesion area, only the upper mat (100) can be separated and replaced with a new upper mat (100), so it can be adjusted according to the user's situation.

[0065] In addition, by providing a waterproof layer on the lower mat (200), performance degradation due to contamination or damage can be prevented and avoided, and it is also possible to replace and reuse the upper mat (100).

[0066] Figure 3 shows a micro-electrical stimulation scar band manufactured with a structure as shown in Figure 1 by wrapping a conductive thread (silver-coated synthetic fiber thread) as a wire around a 0.5 cm lower mat consisting of synthetic fiber fabric (bandage)-silicone-synthetic fiber fabric (bandage), and then laminating a polyurethane (PU) upper mat coated with adhesive, and measuring the magnitude of the electrical stimulation generated by the micro-electrical stimulation scar band while it is attached with one end of the conductive thread touching the arm.

[0067] The electrical stimulation measurement results presented below were obtained by the following method. The electrical stimulation measurement method involves attaching two electrodes of a multimeter to a conductive thread (first area) in contact with the skin and to the skin, respectively, and then calculating the output electric field (mV / mm) by dividing the potential difference (mV) measured at the two electrodes by the distance (1 mm) between the two electrodes. At this time, alternating current electrical energy that is not used and is wasted in electronic devices was used as the input energy source, and for this purpose, the output was measured after placing a hand on a laptop.

[0068] When measuring, the basic noise electric field generated in the human body was measured without wearing the micro-electric stimulation scar band, and the value was plotted as "W / O" in the drawing. After measuring the basic noise electric field, the micro-electric stimulation scar band of the present invention manufactured according to Fig. 1 was worn, and the output electric field was calculated according to the method described above, and the value was plotted as "w / input(basic)".

[0069] In addition, a micro-electrical stimulation scar band was manufactured with a structure as shown in Fig. 1, except for using a lower mat without a waterproof layer, and the output electric field and potential difference were calculated according to the method described above and plotted as "waterproof layer X scar band".

[0070] In addition, a micro-electrical stimulation scar band was manufactured with a structure as shown in FIG. 1, except that a bottom mat without a waterproof layer was used, straight wires (conductive threads) were laminated on the upper and lower surfaces of the bottom mat respectively and the two wires were electrically connected with aluminum foil, and the output electric field and potential difference were calculated according to the method described above and the values ​​were shown as a "straight scar band."

[0071] As shown in the measurement results illustrated in FIG. 3, it was confirmed that the scar band according to the present invention, which has a waterproof layer, has a significantly superior output electric field compared to a scar band without a waterproof layer. Therefore, it was confirmed that it is most desirable for the scar band according to the present invention to have a waterproof layer within the lower mat (200). Furthermore, it was found that when the wire is structured as a single closed circuit loop (300) on the lower mat, as in the scar band of the present invention, superior electrical stimulation is applied to the human body compared to a straight scar band (separated wires connected by foil). In other words, it was confirmed that the scar band of the present invention can induce high electrical stimulation with a small surface area.

[0072] As described above, in an embodiment of the invention, a micro-electrical stimulation scar band can be provided that utilizes bio-triboelectricity to provide micro-stimulation to a wound or scar area without an external power source, thereby activating damaged or abnormal cells to return to a normal state, which allows the wound area to heal early and simultaneously prevents scarring. Additionally, since the upper mat (100) is easy to replace, if hemostasis is required by checking the degree of contamination, a hemostatic effect can be achieved by providing multiple layers of lower mats (200) and applying pressure. Such effects of the invention can be applied and utilized in various ways in the field of adhesive bandages without departing from the scope of the technical concept of the invention.
