Description

Electrical Muscle Stimulation Device for ESG Management

[0001] The present invention relates to an electric muscle stimulation device for ESG management, and more specifically, to a sanitary pad-type electric muscle stimulation device for ESG management, which includes a conductive fiber or electric stimulation pad with an improved shape to enable resource recycling on one side of the sanitary pad for ESG management, and which allows the user to have the effect of Kegel exercise for preventing and treating urinary incontinence.

[0002] In general, incontinence panties, sanitary pads, diapers, etc. that are intended to absorb secretions or moisture use absorbent pads to absorb and store secretions or moisture, and one or more layers of woven or non-woven fabrics such as silk, cotton, or cotton with moisture absorption are used.

[0003] These absorbent pads have the disadvantage of restricting mobility by being formed by overlapping them over panties. Furthermore, urinary incontinence is a condition in which urine leaks involuntarily, regardless of one's will. With the recent increase in life expectancy and the aging population, the prevalence of urinary incontinence is also increasing. Most patients experience involuntary urine leakage when straining their abdomen, and some even experience urine leakage from simple actions such as sneezing or laughing loudly.

[0004] In particular, the diapers worn by patients lying in nursing hospitals should be changed on average 5 to 6 times a day, but due to lack of manpower, they are only changed two to three times a day, which frequently causes patients to develop bad odors, such as urine odor, and bedsores.

[0005] Additionally, most of these patients have a cold and often frigid lower abdomen, and suffer from frequent cystitis due to weak urinary excretion. Urinary incontinence is more common in women than in men, as their urethras are shorter and the pelvic muscles that support the bladder and urethra are more easily weakened by pregnancy and childbirth. More than 40% of postpartum women in Korea experience inconveniences related to urinary incontinence, yet personal shame hinders public awareness, hindering effective improvement efforts.

[0006] In particular, patients who suffer from urinary incontinence, which is when urine leaks out regardless of their will, are more likely to be reluctant to go out and engage in external activities due to a great sense of loss and increased anxiety. However, incontinence panties are being used to eliminate anxiety and provide convenience when engaging in such activities.

[0007] These diverse products are not recycled and are ultimately discarded, posing a resource recycling challenge. Currently, companies worldwide are being urged to make efforts to use environmentally friendly products, and these elements are being defined as ESG (Environmental, Social, and Governance).

[0008] As societal interest in ESG (Environmental, Social, and Governance) grows, interest in the waste management industry is growing globally. ESG stands for Environmental, Social, and Governance, a company's non-financial factors. It emphasizes the importance of transparent management practices, including environmentally friendly management, social responsibility, and improved governance, in corporate management activities to achieve sustainable development.

[0009] Korean Patent Publication No. 10-2472838 relates to a pelvic floor muscle stimulation device. It discloses a pelvic floor muscle stimulation device that can be used without burden by being worn easily on underwear and without feeling any psychological burden, including shame, and that can stimulate the pelvic floor muscles through electrical muscle stimulation therapy.

[0010] However, there is a problem in that separate components such as a tension control unit are required to ensure that the underwear and stimulation device with the pocket portion formed can adhere closely to the body.

[0011] Korean Patent Publication No. 10-246818 relates to an electrode device, which includes a body having a contact side and a non-contact side, the body extending longitudinally between a first end and a second end, the body defining an internal outlet from the contact side to the non-contact side, a plurality of spaced apart activatable conductive regions positioned on the contact side of the body and electrically insulated from the non-contact side, the contact side defining a surface and profile configured to interface with perineal tissue at a location where a current generated by the conductive regions is permitted to penetrate the perineal tissue and stimulate at least one muscle therein of an individual or animal.

[0012] However, although a form that can be attached to underwear is presented, there are problems such as the need to use a separate absorbent pad and the need for separate washing or sterilization in order to reuse the electrode device.

[0013] Korean Utility Model Registration No. 20-0339987 relates to physical therapy panties, and discloses physical therapy panties that are effective in treating urinary incontinence, etc. through repetition of muscle tension and relaxation by applying low-frequency signals, heat, electrical stimulation, etc. to sphincters, etc., and can also create therapeutic effects through negative ions, far-infrared rays, etc.

[0014] However, since the physical therapy components are attached to the panties themselves, there is a problem that they are difficult to separate, making them unsanitary and reusable.

[0015] Chinese Patent Publication No. 117062650 relates to a device for treating urinary incontinence, and discloses a device applicable to a diaper, which includes a sensor for detecting urination and a stimulation pad configured to provide stimulation to the wearer.

[0016] However, there is a problem that the stimulation generating unit, which generates a signal to stimulate the user, is located on the user's abdomen or back rather than inside the diaper, making it inconvenient to use in real life and causing shame when used.

[0017] Therefore, there is a need to develop a sanitary pad-type electrical muscle stimulation device for ESG management that includes conductive fibers or electrical stimulation pads with improved shapes to enable resource recycling on one side of the sanitary pad for ESG management and allows the user to perform Kegel exercises to prevent and treat urinary incontinence.

[0045] The present invention will be described in more detail below with reference to the attached drawings. However, the attached drawings are merely examples intended to facilitate the description and scope of the technical concept of the present invention and are in no way intended to limit or alter the technical scope of the present invention. Furthermore, it will be apparent to those skilled in the art that various modifications and variations are possible within the scope of the technical concept of the present invention based on these examples.

[0046] In addition, the terms and words used in this specification and claims should not be interpreted as limited to their conventional or dictionary meanings, but should be interpreted with meanings and concepts that conform to the technical idea of ​​the present invention based on the principle that the inventor can appropriately define the concept of the term to best explain his or her own invention. Therefore, it should be understood that the embodiments described in this specification are merely the most preferred embodiments of the present invention and do not represent all of the technical idea of ​​the present invention, and that there may be various equivalents and modified examples that can replace them at the time of this application.

[0047] Figure 1 is a conceptual diagram of a sanitary pad-type electrical stimulation device according to one embodiment of the present invention.

[0048] The present invention provides a sanitary pad-type electric muscle stimulation device (1) comprising a body contact surface (100) which is a surface that comes into contact with the body, an impurity absorption surface (110) located at the center of the body contact surface for absorbing impurities discharged from the body, an underwear contact surface (120) which is a surface that comes into contact with underwear on the other side of the body contact surface, a wing (130) for attaching to the underwear, and a sanitary pad body part (10) in which an absorbent layer made of an absorbent material is formed on the inside of the impurity absorption surface, and an electric stimulation part including a control board (200) located at one side of the sanitary pad body part for controlling electric stimulation, and a connecting line (210) for transmitting an electric signal generated from the control board.

[0049] The above electrical stimulation unit refers to electrical muscle stimulation (EMS) or electrical stimulation therapy (EST).

[0050] Intermittent direct current (IDC), alternating current (AC), and pulsed current (PC) can be used for muscle electrical stimulation.

[0051] The above electrical stimulation may be applied at any one of low frequency 1,000 Hz or less, medium frequency 1,000 to 10,000 Hz, and high frequency 10,000 Hz or more.

[0052] When electrical stimulation is applied, the pudendal nerve is stimulated, and at this time, the pelvic floor muscles directly contract due to the efferent nerves, and reflex contraction occurs due to the afferent nerves, and this reflex contraction can strengthen the pelvic floor muscles. A low current of 35 mA or less only contracts the pelvic floor muscles, but a high current of 65 mA or more has the dual effect of pelvic floor muscle contraction and bladder relaxation. A high frequency of 20-50 Hz is required to contract the urethral sphincter, and a low frequency of 5-10 Hz may be required to suppress bladder activity.

[0053] The above electrical stimulation can use a microcurrent of 25-50 Hz and 0-50 mA (500 ohm), and double frequency stimulation simultaneously provides different frequencies of 1-1,000 Hz to 1 channel (F1) and 2 channels (F2), and can mainly use a mixed frequency (F=F1-F2) of 300 Hz or less within a duty of 40%.

[0054] By applying silicone electrodes, pain and discomfort at the contact surface between the electrode and the skin can be minimized.

[0055] In addition, part or all of the body contact surface of the sanitary pad body portion includes conductive fibers, and one side of the connecting line and the conductive fibers (300a) are connected to apply electrical stimulation to the body.

[0056] Additionally, the conductive fiber may be formed in a pattern of one or more of a surface, a dot, and a line along the outer side of the impurity absorption surface.

[0057] Figure 2 is a perspective view of a sanitary pad-type electrical stimulation device according to one embodiment of the present invention.

[0058] In addition, when the pattern of the conductive fiber is formed by including dots, a fiber connecting member connecting each dot may be additionally included so that an electric signal can be transmitted.

[0059] FIG. 3 is a conceptual diagram of a sanitary pad-type electric stimulation device in which the control board of the sanitary pad is separated along a break line according to one embodiment of the present invention.

[0060] In addition, a break line (400) is formed on one side of the underwear contact surface, and the break line can be torn and opened when rolling to discard the used sanitary pad.

[0061] In addition, the control board of the electric stimulation unit is located on the inside between the underwear contact surface and the body contact surface, and when the sanitary pad is rolled to be disposed of, the control board is opened and protrudes outward, making it retrievable.

[0062] In addition, since the above body contact surface directly touches the user's body, it may be formed of rayon to minimize or prevent irritation to the skin, and specifically, may be viscose rayon extracted from eucalyptus trees.

[0063] In addition, the electrical stimulation unit may additionally include an electrical stimulation pad (300b) that applies electrical stimulation to the body on one side of the connecting line.

[0064] In addition, the above-mentioned electric stimulation pad may be arranged in one or more shapes, including at least one of a linear shape and a planar shape, on the body contact surface.

[0065] Additionally, the electrical stimulation pad may include an adhesive material made of silicone, and the pad may be formed in part or in whole by including an adhesive material.

[0066] In addition, the adhesive material may be formed as an adhesive layer, and an electric stimulation pad may be attached to one surface of the adhesive layer or may be formed in a form in which only a portion is exposed by retracting a portion of the adhesive layer.

[0067] In addition, the adhesive material is capable of deformation and elasticity, so that it can easily adhere to the user's body.

[0068] In addition, the control board may be for electrical stimulation control, the conductive fiber and the electrical stimulation pad may be for receiving a signal from the control board and generating electrical stimulation in the muscle, and the connecting line may be for connecting the control board and the conductive fiber or the electrical stimulation pad.

[0069] In addition, the control board may be equipped with a battery and used as a power source to generate an electric signal to the conductive fiber or electric stimulation pad through the connecting wire.

[0070] Additionally, the above battery may be a coin-type battery.

[0071] Additionally, one side of the battery provided on the control board may include an activation vinyl to prevent it from being operated in advance.

[0072] In addition, the control board includes a memory function, and operation information such as the time and intensity of electric signal generation are stored in advance, so that the control board can start operation by being worn by the user without any separate operation, and operation can stop when the memorized operation information ends.

[0073] Additionally, it can operate continuously until the batteries are completely depleted.

[0074] In addition, the control board may have a size of less than 3 cm in width, length, and height, and the height of the CR2016, which is called a popular coin or button battery, is 0.16 cm, the height of the CR2025 is 0.25 cm, the height of the CR2032 is 0.32 cm, and the height of the LR1154 or SR1154 is 0.54 cm, so it may be desirable to have a minimum height that can accommodate these. For example, the height may preferably be configured as 1.0 cm or less, 0.6 cm or less, 0.35 cm or less, 0.25 cm or less, and 0.20 cm or less, but this is only an example, and the height may vary depending on the shape and internal configuration of the device.

[0075] Additionally, the length and width may also vary depending on the internal configuration.

[0076] Additionally, at least one of the absorbent layer, the impurity absorbing surface, the body contact surface, and the underwear contact surface may include a waterproof function on one side.

[0077] For the above waterproofing function, a separate waterproofing layer may be formed, and for the above waterproofing function, a biodegradable composition including at least one of adipate terephthalate (poly(butylene adipate-co-terephthalate), PBAT) and poly(lactic acid), PLA, and at least one of polyester, nylon, and polyurethane (TPU: Temperature polyurethane) may be included.

[0078] In addition, the above-mentioned nylon refers to a fiber or film processed using a synthetic polymer based on an aliphatic or semi-aromatic polyamide.

[0079] In addition, the impurity absorbing surface may be made of at least one of terry or non-woven fabric, and the impurity absorbing surface may be a material having antibacterial and deodorizing functions, and may absorb moisture more efficiently through absorption processing.

[0080] Additionally, an antibacterial and deodorizing layer may be additionally included on one side of the impurity absorption surface.

[0081] In addition, the antibacterial and deodorizing layer may be composed of at least one selected from an antibacterial and deodorizing agent and a dark ion catalyst, preferably a mixture of an antibacterial and deodorizing agent and a dark ion catalyst in a weight ratio of 1:2 to 3.

[0082] The antibacterial deodorant maintains the best comfortable condition by adsorbing odor molecules and removing microorganisms, and may be composed of 85 to 99 wt% of base solution, 0.01 to 5 wt% of chitosan, 0.01 to 5 wt% of organic acid, and 0.01 to 5 wt% of ceramic powder. The antibacterial deodorant satisfying the above-mentioned range may have a viscosity of 500 to 6,000 cps and a pH of 2 to 4.

[0083] In addition, the base solution may contain at least one selected from distilled water, peppermint extract, lemongrass extract, moringa leaf extract, rosemary extract, pennyroyal extract, eucalyptus extract, and coffee ground extract, and may be an aqueous solution diluted with natural substances to enhance antibacterial, deodorizing, and far-infrared ray emission functions. Such a base solution may be included in an amount of 85 to 99 wt% based on the total wt% of the antibacterial and deodorizing agent.

[0084] In addition, the above chitosan plays a role in maximizing antibacterial, deodorizing, and far-infrared ray emission effects, and can be a general term for a substance obtained by deacetylating chitin contained in the shells of crabs, lobsters, shrimps, clams, and oysters.

[0085] Figure 4 is a cross-sectional view of a sanitary pad-type electrical stimulation device according to one embodiment of the present invention.

[0086] In addition, on the other hand, chitosan having a molecular weight of 1,000 to 2,000,000 g / mol, preferably 10,000 to 1,000,000 g / mol, and a viscosity of 500 to 1,200 cps, preferably 700 to 1,200 cps, can be used. If the molecular weight of chitosan is less than 1,000 g / mol, the properties of chitosan as a polymer are bound to decrease, and it is difficult to perform its role as a natural binder, and if it exceeds 2,000,000 g / mol, the binding between chitosan and organic acid is not well formed, and the touch may be poor. If the viscosity of chitosan is less than 500 cps, durability problems may occur, and if it exceeds 1,200 cps, compatibility may be reduced. Such chitosan may be included in an amount of 0.01 to 5 wt% based on the total weight of the antibacterial and deodorant. When chitosan satisfies the above-mentioned range, the antibacterial, deodorizing, and far-infrared ray emission effects may be maximized.

[0087] In addition, the organic acid serves to dissolve chitosan in the base solution, and may be used at least one selected from mandelic acid, malic acid, lactic acid, citric acid, alginic acid, acetic acid, ascorbic acid, calcium acetate, formic acid, monohydrate, butyl lactic acid, ethyl lactic acid, and glycerin. Preferably, citric acid may be used so as to maximize antibacterial properties by combining with chitosan. The organic acid may be included in an amount of 0.01 to 5 wt% based on the total weight of the antibacterial and deodorant. If the organic acid is less than 0.01 wt%, commercialization of the product may be difficult, and if it exceeds 5 wt%, the feel may be poor.

[0088] In addition, the ceramic powder may include at least one selected from among diatomaceous earth, biotite, slate mite, muscovite, tourmaline, zeolite, charcoal, graphene, bentonite, germanium, magnetite, graphite, jade, and zirconium oxide, and the average particle size may satisfy a range of 0.01 to 5.0 ㎛, preferably 0.1 to 3.0 ㎛, and most preferably 0.1 to 1.0 ㎛.

[0089] In addition, when the above-mentioned range is satisfied, fiber permeability is enhanced and far-infrared ray emission function can be maximized.

[0090] In addition, the mineral solution serves to further maximize the antibacterial, deodorizing, and far-infrared ray emission functions, and may use at least one selected from sodium chloride, magnesium chloride, calcium chloride, potassium chloride, and sodium gluconate, and may contain 0.01 to 5 wt% of the mineral solution relative to the total wt% of the antibacterial and deodorizing agent.

[0091] In addition, the above-mentioned dark ion catalyst has antibacterial and deodorizing functions by inhibiting the growth of mold and bacteria, and may be composed of 5 to 15 wt% of copper ions, 5 to 15 wt% of titanium ions, 5 to 15 wt% of silver ions, 5 to 10 wt% of essential amino acids, and 60 to 70 wt% of ionized purified water, and may be made on the principle of blood through ionization after nano-ization.

[0092] FIG. 5 is a perspective view of a sanitary pad-type electric stimulation device including an impurity guide member according to one embodiment of the present invention.

[0093] In addition, an impurity guide member (140) may be additionally included on at least one side of the impurity absorption surface or the body contact surface, so that impurities may not be discharged or flow out of the sanitary pad.

[0096] Additionally, the ceramic powder may be included in at least one of the body contact surface or the impurity absorption surface, and may also be formed as a separate layer.

[0097] In addition, by including at least one of the above-mentioned mica powder, kaolinite raw material powder, and white clay composition, far infrared rays or negative ions can be emitted and radiated, and an appropriate pH can be maintained, thereby providing antibacterial and deodorizing functions and preventing and / or suppressing itchiness, rashes, eczema, menstrual cramps, vaginitis (inflammation), etc.

[0098] Additionally, the conductive fiber may include one or more materials selected from carbon, silver nano, and graphene.

[0099] In addition, the conductive fiber may include at least one material selected from the group consisting of carbon, silver nano, graphene, Aero Silver, ceramic yarn, polypropylene, polyurethane, silver, Aero Silver, copper, and charcoal.

[0107] Additionally, the polypropylene yarn can be manufactured by spinning polypropylene having a stereoregular structure polymerized under a fiber catalyst.

[0108] In addition, the polypropylene yarn may be a yarn made from a polymer having an ester bond produced by polymerizing terephthalic acid and ethylene glycol, and due to its hydrophobic nature, it does not get wet with sweat, providing a comfortable wearing experience, blocks an environment for bacterial growth, and provides quick-drying properties.

[0109] Additionally, polypropylene yarn has low thermal conductivity, which can block cold air in winter and prevent body heat from escaping to the outside.

[0110] In addition, polypropylene yarn has a specific gravity of 0.91 g / cm3, so it is lightweight enough to float on water, has strong tensile strength, and can have strong chemical resistance.
