Description

Technical Field

[0001] This application relates to the field of electrode pad technology, specifically to an electrode pad assembly, an electrode pad fixing device, and an electrotherapy device. Background Technology

[0002] Transcutaneous electrical nerve stimulation (TENS) devices are commonly used physical therapy instruments, and the performance of their core component, the electrode pads, directly affects treatment efficacy, user experience, and overall cost. Currently, TENS device electrode pads on the market are mainly divided into two categories: one is the mainstream disposable gel electrode pad, composed of a conductive gel surface and a carbon conductive substrate at the bottom, relying on the gel's adhesiveness to achieve skin adhesion and conduct electrical pulses. However, this type of electrode pad has significant drawbacks: the conductive gel easily attracts dust and debris, and its adhesiveness decays rapidly, typically allowing only single or a few uses. TENS treatments often require high-frequency application, leading to persistently high consumable costs with long-term use; additionally, the gel's adhesive strength is limited, making it prone to detachment during sweating or limb movement, affecting the continuity of treatment. The other type is a reusable, integrated bandage-type electrode, employing a structure combining conductive rubber, conductive silver wire, and fabric, secured to a specific location via Velcro. Although it solves the problem of reuse, it still has many shortcomings: these electrodes are pre-formed into a fixed shape and can only be used on specific areas such as the waist and hands, which is not very versatile and cannot meet the treatment needs of multiple areas of the whole body; moreover, they are mostly integrated with the TENS host, which is not compatible with the device and can only be matched with specific models of instruments; in addition, they are bulky and complicated to wear and operate, completely losing the advantages of flexible and convenient use of gel electrode pads, and the manufacturing cost is high, making it difficult to be widely accepted.

[0003] In summary, among the related technologies, electrode pads either have problems such as high usage cost and easy detachment, or poor versatility and inconvenient operation, making it difficult to meet users' demands for high-frequency treatment, adaptation to multiple parts of the body, and cost-effectiveness.

[0023] Transcutaneous electrical nerve stimulation (TENS) devices are commonly used physical therapy instruments, and the performance of their core component, the electrode pads, directly affects treatment efficacy, user experience, and overall cost. Currently, TENS device electrode pads on the market are mainly divided into two categories: one is the mainstream disposable gel electrode pad, composed of a conductive gel surface and a carbon conductive substrate at the bottom, relying on the gel's adhesiveness to achieve skin adhesion and conduct electrical pulses. However, this type of electrode pad has significant drawbacks: the conductive gel easily attracts dust and debris, and its adhesiveness decays rapidly, typically allowing only single or a few uses. TENS treatments often require high-frequency application, leading to persistently high consumable costs with long-term use; additionally, the gel's adhesive strength is limited, making it prone to detachment during sweating or limb movement, affecting the continuity of treatment.

[0024] In summary, among the related technologies, electrode pads either have problems such as high usage cost and easy detachment, or poor versatility and inconvenient operation, making it difficult to meet users' demands for high-frequency treatment, adaptation to multiple parts of the body, and cost-effectiveness.

[0025] Please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of an electrode sheet provided in an embodiment of this application. Figure 2 This is a schematic diagram of the cross-sectional structure of an electrode sheet provided in an embodiment of this application. Figure 1 , Figure 3 This is a schematic diagram of the cross-sectional structure of an electrode sheet provided in an embodiment of this application. Figure 2 , Figure 4 This is a schematic diagram of a lateral opening for a fixing member through which an electrode sheet is inserted, provided in an embodiment of this application.

[0026] This application provides an electrode assembly 100 to solve the technical problems in the related art, such as high cost of use, easy detachment, poor versatility, and inconvenient operation of electrode sheets.

[0027] It should be noted that, in this embodiment, the electrode assembly 100 of this application is applied to a transcutaneous electrical nerve stimulation (TENS) device. In other embodiments, the electrode assembly 100 may also be applied to other electrotherapy devices, and this application does not impose any restrictions on this.

[0028] The electrode assembly 100 includes an electrode 10, which includes a body portion 11 and a first arched portion 12 protruding from the body portion 11. The first arched portion 12 has a transverse opening 121 and a conductive hole 122. The transverse opening 121 penetrates the first arched portion 12 along a first direction D1. The transverse opening 121 is used to pass through a fixing member 200, and the conductive hole 122 is used to pass through a conductive member.

[0029] It should be noted that the electrode assembly 100, as a three-dimensional device, has a length direction, a width direction, and a height direction. In this embodiment and in the following text and even in the accompanying drawings, the first direction D1, the second direction D2, and the third direction D3 are used to indicate the length direction, the width direction, and the height direction, respectively. Specifically, the first direction D1 is the length direction, the second direction D2 is the width direction, and the third direction D3 is the height direction.

[0030] The electrode assembly 100 includes the electrode sheet 10. Optionally, the electrode sheet 10 includes at least one of a conductive silicone electrode sheet, a conductive rubber electrode sheet, a conductive plastic electrode sheet, and a conductive fabric electrode sheet. In other words, the material of the electrode sheet 10 includes at least one of conductive silicone, conductive rubber, conductive plastic, and an insulating fabric protective cover. The conductive fabric electrode sheet includes a conductive silver wire woven fabric composite, and the insulating fabric protective cover includes woven fabric.

[0031] The electrode pad 10 includes the body portion 11, which serves as the basic support structure of the electrode pad 10 and is shaped to fit the skin. The body portion 11 is the direct carrier for the transmission of electrotherapy pulses.

[0032] The body portion 11 of the electrode pad 10 is directly attached to the skin, receives the electrotherapy pulses transmitted by the conductive element, and evenly conducts them to the treatment site, providing a basic conductive path for electrotherapy.

[0033] The body part 11 is made of a flexible material, in other words, the material of the body part 11 has deformable characteristics. The deformable characteristics of the body part 11 ensure that the body part 11 can fit closely to the skin, ensure the stability of electrical signal transmission, and avoid the attenuation of treatment effect due to poor contact.

[0034] The electrode pad 10 further includes the first arched portion 12, which protrudes from the side of the body portion 11 away from the skin. The first arched portion 12 is provided with the transverse opening 121 and the conductive hole 122. The transverse opening 121 is used to insert the fixing member 200.

[0035] It should be noted that the fastener 200 includes, but is not limited to, straps, adhesive tapes, or other fastening structures, and the conductive component includes, but is not limited to, metal rods and cables; this application does not impose any restrictions on these.

[0036] Furthermore, in one embodiment, the lateral opening 121 forms a tight frictional fit with the fixing member 200, which not only achieves stable positioning of the electrode plate 10 but also allows for free movement and position adjustment to adapt to the needs of different treatment sites. The conductive hole 122 precisely matches the conductive member to ensure smooth transmission of electrical signals.

[0037] It should be noted that the gel electrode pads in related technologies rely on the adhesive layer and are disposable consumables, with a reference cost of US$0.5 per pair, resulting in high cumulative costs over long-term use. In contrast, the electrode pad 10 described in this application is made of durable conductive rubber, and its service life is much longer, with an overall lifespan of over 10,000 cycles, eliminating the need for frequent replacements and significantly reducing long-term consumable expenses.

[0038] Furthermore, in related technologies, gel electrode pads rely on adhesive layers for fixation. However, this adhesiveness rapidly diminishes after sweating, activity, or prolonged use, leading to detachment. This application addresses this by inserting the fixing member 200 through the transverse opening 121 of the first arched portion 12. The fixing member 200 provides physical bonding, replacing adhesive fixation. This physical bonding method adapts to different stress states, maintaining a stable fit regardless of limb movement or static application, thus completely eliminating the risk of detachment.

[0039] Furthermore, the gel electrode pads in related technologies are limited by the adhesive strength and shape of the adhesive layer, resulting in poor adaptability to moving parts such as joints. In contrast, the main body 11 and the shielding part 21 of this application are made of flexible materials and have deformable characteristics. Combined with the flexible fixing method provided by the lateral opening 121, they can be adapted to limb joints such as wrists and knees through straps, and can also be attached to flat body parts such as waist, abdomen, and shoulders through adhesive patches, achieving full-body coverage in multiple scenarios.

[0040] In the electrode assembly 100 provided in this application, the electrode 10 includes a body portion 11 and a first arched portion 12 protruding from the body portion 11. The first arched portion 12 has a transverse opening 121 and a conductive hole 122. The transverse opening 121 extends through the first arched portion 12 along a first direction D1 and is used to pass through a fixing member 200. The conductive hole 122 is used to pass through a conductive member. The electrode 10 can be fixed by the fixing member 200. The electrode 10 has a long service life and does not need to be replaced frequently, significantly reducing the cost of use. Furthermore, the electrode 10 is fixed by the fixing member 200, which provides a flexible fixing method. It can be adapted to movable joints such as the wrist and knee, as well as planar areas such as the waist, abdomen, and shoulders, achieving electrotherapy adaptation for multiple areas of the whole body.

[0041] Please refer to Figures 5 to 12 , Figure 5 This is a schematic diagram of the structure of a protective cover provided in an embodiment of this application. Figure 6 This is a schematic diagram of the bottom structure of a protective cover provided in an embodiment of this application. Figure 7 This is a schematic cross-sectional structure of a protective cover provided in an embodiment of this application.

Figure 1 , Figure 12 This is a schematic cross-sectional view of an electrode assembly provided in an embodiment of this application. Figure 2 .

[0042] In one embodiment, the electrode assembly 100 further includes a protective cover 20 disposed on the electrode 10. The protective cover 20 includes a shielding portion 21 and a second arched portion 22 protruding from the shielding portion 21. The shielding portion 21 covers the side of the body portion 11 facing the shielding portion 21. The second arched portion 22 is disposed corresponding to the first arched portion 12 and is used to accommodate the first arched portion 12. The two sides of the second arched portion 22 are provided with through holes 211 corresponding to the transverse opening 121 and the conductive hole 122.

[0043] Optionally, the protective cover 20 includes at least one of an insulating silicone protective cover, an insulating rubber protective cover, and an insulating plastic protective cover. Further optionally, in other embodiments, the protective cover 20 may also be in the form of a coating, fabric, plastic sheet, etc., to provide full or partial insulation coverage and decoration for the electrode sheet 10; this application does not impose any limitations on this.

[0044] The protective cover 20 includes a shielding portion 21, which completely covers the side of the main body 11 facing the shielding portion 21, exposing only the conductive surface of the bottom of the main body 11 that contacts the skin. The shielding portion 21 provides both insulation and aesthetic appeal. Specifically, it isolates the conductive surface of the main body 11, preventing accidental contact with conductive parts. Simultaneously, it conceals the internal structure, enhancing the overall aesthetics of the electrode assembly 100. The shielding portion 21 avoids discomfort or safety hazards caused by contact between non-treatment areas of the body and the conductive surface, balancing practicality and visual appeal without affecting the conductive function of the main body 11.

[0045] Similarly, the material of the shielding part 21 can also be a flexible material. In other words, the material of the shielding part 21 has deformable characteristics. The deformable characteristics of the shielding part 21 ensure that the main body part 11 can deform normally and fit closely to the skin.

[0046] The protective cover 20 also includes a second arched portion 22, which protrudes from the shielding portion 21 on the side away from the electrode sheet 10. The shape and size of the second arched portion 22 are precisely matched with the first arched portion 12, and can completely accommodate the first arched portion 12. The second arched portion 22 is provided with a through hole 211 corresponding to the position of the transverse opening 121 and the conductive hole 122. The size of the through hole 211 is consistent with the size of the transverse opening 121 and the conductive hole 122.

[0047] The second arched portion 22 provides a wrapping protection for the first arched portion 12, while avoiding the fixing member 200 and the conductive member through the through hole 211, ensuring that the fixing and conductive functions of the electrode sheet assembly 100 are not affected.

[0048] Furthermore, the second arched portion 22 can isolate the conductive surface of the first arched portion 12, preventing users from accidentally touching the conductive parts and avoiding discomfort or safety hazards caused by contact between non-treatment areas of the human body and the conductive surface. In addition, the second arched portion 22 can effectively reduce wear on the first arched portion 12 during use and storage, extending the service life of the component. The receptive design of the second arched portion 22 makes the overall structure compact, and the precise matching of the through-hole 211 ensures that the fixing member 200 passes through smoothly and the conductive member is connected without functional interference.

[0049] In one embodiment, the body portion 11 of the electrode sheet 10 has a shape that includes square and circular.

[0050] In other words, in one embodiment, the body portion 11 of the electrode sheet 10 can be square, specifically, the body portion 11 has dimensions of 40mm × 40mm. In another embodiment, the body portion 11 of the electrode sheet 10 can be circular, specifically, the diameter of the body portion 11 is 50mm.

[0051] The body part 11 has a square and a round shape. Both shapes of the body part 11 are flat structures. The bottom surface that contacts the skin maintains a complete conductive surface. The first arched part 12 can be stably protruded on the side away from the skin and can be precisely adapted to the shielding part 21 of the protective cover 20.

[0052] The square-shaped body part 11 has regular edges and corners, making it suitable for fitting large, flat areas such as the waist, abdomen, and shoulders, providing a more stable contact area. The round-shaped body part 11 has no sharp edges and corners, making it suitable for fitting curved areas or areas near active joints such as the wrist, elbow, and knee, avoiding friction from sharp edges against the skin. Both shapes are classic shapes of the electrode pads 10 in electrotherapy devices, so users do not need to adapt to new forms, which can lower the usage threshold of the electrode pad assembly 100 and increase its user acceptance.

[0053] In other embodiments, the body portion 11 of the electrode sheet 10 may also be elliptical, triangular, pentagonal or other shapes, and this application does not limit this.

[0054] Please refer to Figures 5 to 12 In one embodiment, the width of the first arched portion 12 ranges from 20mm to 60mm, and the height of the first arched portion 12 ranges from 3mm to 15mm.

[0055] Specifically, the width of the first arched portion 12 ranges from 20mm to 60mm, forming a reasonable proportion with the mainstream size of the main body portion 11, neither exceeding the edge of the main body portion 11 nor being too narrow to cause insufficient structural load-bearing capacity.

[0056] Optionally, the width of the first arched portion 12 can be 20mm, or 21mm, or 22mm, or 23mm, or 25mm, or 27mm, or 29mm, or 30mm, or 32mm, or 33mm, or 35mm, or 36mm, or 38mm, or 40mm, or 42mm, or 45mm, or 46mm, or 49mm, or 50mm, or 51mm, or 53mm, or 55mm, or 57mm, or 60mm, or other values ​​within the range of 20mm-60mm, and this application does not impose any restrictions on this.

[0057] Specifically, the height of the first arched portion 12 is set to 3mm-15mm, with sufficient space reserved in the height direction to accommodate the conductive hole 122 and the conductive component, while also forming a receiving fit with the second arched portion 22 of the protective cover 20.

[0058] Optionally, the height of the first arched portion 12 can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, or other values ​​within the range of 3mm-15mm. This application does not impose any restrictions on this.

[0059] It should be noted that the width and height of the first arched portion 12 are range designs rather than fixed values. They can be flexibly adjusted according to the specific shape of the main body portion 11, the specifications of the fastener 200, and the length of the conductive component, taking into account both versatility and adaptability. This should not be construed as a limitation of this application.

[0060] Please refer to Figures 1 to 12 In one embodiment, the width of the lateral opening 121 ranges from 20mm to 60mm, and the height of the lateral opening 121 ranges from 1mm to 3mm.

[0061] The width of the transverse opening 121 is in the range of 20mm-60mm, which is completely matched with the width range of the first arch 12. This ensures that the transverse opening 121 does not exceed the edge of the first arch 12 after passing through it, and can completely cover the width of the conventional fastener 200, ensuring that the fastener 200 can be smoothly inserted and form effective contact with the inner wall of the transverse opening 121.

[0062] The height of the transverse opening 121 ranges from 1mm to 3mm, and it is a vertically continuous gap, precisely matching the thickness of the fixing member 200. Specifically, in one embodiment, the thickness of the fixing member 200 is greater than the height of the transverse opening 121. The height of the transverse opening 121, ranging from 1mm to 3mm, precisely matches the thickness of the fixing member 200, forming a tight but not jamming fit. This ensures stable positioning of the electrode assembly 100 through the friction between the inner wall of the transverse opening 121 and the fixing member 200, while preventing the fixing member 200 from being difficult to insert due to excessive narrowness, or the electrode assembly 100 from sliding freely on the fixing member 200 due to excessive width.

[0063] It should be noted that the preferred embodiment is that the thickness of the fastener 200 is greater than the height of the transverse opening 121. In other embodiments, the thickness of the fastener 200 may be less than or equal to the height of the transverse opening 121, and this application does not impose any restrictions on this.

[0064] The width of the lateral opening 121 ranges from 20mm to 60mm, and the height ranges from 1mm to 3mm. The width of the lateral opening 121 ensures full contact with the fixing member 200, and the height range ensures a tight fit with the fixing member 200. This enhances the friction between the electrode assembly 100 and the fixing member 200, allowing the electrode assembly 100 to stably adhere to the skin even during limb activity or sweating, completely solving the problem of traditional gel electrode pads 10 easily falling off. Furthermore, the precise fit between the lateral opening 121 and the fixing member 200 allows for smooth and unobstructed installation and adjustment of the electrode assembly 100. It prevents the fixing member 200 from getting stuck due to an overly narrow lateral opening 121, and also prevents the electrode assembly 100 from sliding or shifting due to an overly wide lateral opening 121, allowing users to quickly complete installation and position adjustment.

[0065] Optionally, the width of the lateral opening 121 can be 20mm, or 21mm, or 22mm, or 23mm, or 25mm, or 27mm, or 29mm, or 30mm, or 32mm, or 33mm, or 35mm, or 36mm, or 38mm, or 40mm, or 42mm, or 45mm, or 46mm, or 49mm, or 50mm, or 51mm, or 53mm, or 55mm, or 57mm, or 60mm, or other values ​​within the range of 20mm-60mm. This application does not impose any restrictions on this.

[0066] Optionally, the height of the lateral opening 121 can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, or other values ​​within the range of 1mm-3mm. This application does not impose any restrictions on this.

[0067] It should be noted that the width and height of the lateral opening 121 are designed as intervals rather than fixed values. They can be flexibly adjusted according to the specific specifications of the fastener 200 and the size of the body 11, while maintaining structural compatibility with the first arched part 12. This should not be construed as a limitation of this application.

[0068] Please refer to Figures 1 to 12 In one embodiment, the conductive hole 122 is a through hole, the conductive hole 122 is located above the transverse opening 121, and the conductive hole 122 penetrates the first arched portion 12 along the first direction D1.

[0069] The conductive hole 122 is a through hole; in other words, it is a hole that passes through both sides of the first arched portion 12, rather than a blind hole. Specifically, the conductive hole 122 is a through hole, ensuring that the conductive component can completely pass through the first arched portion 12, achieving a more stable plug-in connection and avoiding poor contact caused by only partially inserting the conductive component.

[0070] The conductive hole 122 is located above the transverse opening 121, that is, on the first arched portion 12, and the conductive hole 122 and the transverse opening 121 below it are arranged in a vertically layered manner. Specifically, the conductive hole 122 and the transverse opening 121 below it are arranged in a vertically layered manner to avoid spatial interference between the conductive component and the fixing member 200 passing through the transverse opening 121 below, so that the structures of the fixing member 200 and the conductive component do not interfere with each other.

[0071] The conductive hole 122 extends along the first direction D1, and the direction of penetration of the conductive hole 122 is completely consistent with the direction of penetration of the transverse opening 121. Openings in the same direction are easier to mass-produce. The conductive hole 122 simplifies the processing flow of the first arched part 12 and reduces the processing difficulty at the production end. Furthermore, it also makes the insertion direction of the conductive component consistent with the insertion direction of the fixing component 200. The direction of the user's actions of inserting and removing the conductive component and inserting the fixing component 200 is unified, making the operation more convenient and reducing the complexity of user operation.

[0072] Please refer to Figures 1 to 12 In one embodiment, the conductive hole 122 is a blind hole, the number of conductive holes 122 is at least one, and the conductive hole 122 is provided at at least one end of the first arched portion 12 at opposite ends along the second direction D2, wherein the conductive hole 122 extends along the second direction D2, and the second direction D2 is perpendicular to the first direction D1.

[0073] Specifically, the conductive hole 122 is a blind hole, extending inward from only one side of the first arched portion 12 without penetrating the entire first arched portion 12. The bottom support structure of the blind hole makes the conductive component more stable after insertion, reducing insertion and removal wobbling, and providing bottom limiting support for the conductive component. The number of conductive holes 122 is at least one, and one or more can be set according to needs, arranged at opposite ends or either end of the first arched portion 12 along the second direction D2. The conductive hole 122 extends along the second direction D2, and its depth direction is perpendicular to the lateral penetration direction of the lateral opening 121 at 90°, consistent with the longitudinal structural direction of the first arched portion 12.

[0074] The layout of the horizontal opening 121 and the vertical conductive hole 122 forms a functional zone that is horizontally fixed and vertically connected. The vertical conductive hole 122 and the horizontal opening 121 are completely offset from each other, which not only avoids interference between the conductive component and the fixing component 200 inserted therein, but also allows the connection direction of the conductive component to be adjusted according to the installation position.

[0075] In one embodiment, there are multiple conductive holes 122, including a first conductive hole and a second conductive hole. The first conductive hole and the second conductive hole are respectively disposed at both ends of the first arched portion 12 along the second direction D2, and the first conductive hole and the second conductive hole extend along the second direction D2. Both the first conductive hole and the second conductive hole can be used to pass through the conductive component.

[0076] In one embodiment, the number of conductive holes 122 is plurality of, and each conductive hole 122 includes a blind hole, which is located at at least one end of the first arched portion 12 at opposite ends along the second direction D2. The blind hole extends along the second direction D2. The conductive hole 122 also includes a through hole, which penetrates the first arched portion 12 along the first direction D1. The transverse and longitudinal insertion hole design on the first arched portion 12 makes the connection method of the conductive component flexible, so that the most suitable connection point and direction of the conductive component can be selected according to the specific installation location, avoiding interference with the body and avoiding the part of the electrode plate 10 in contact with the skin by external force during use.

[0077] Specifically, the conductive hole 122 includes a bidirectional layout of transverse through holes and longitudinal blind holes, allowing the conductive component connection to have dual degrees of freedom in terms of direction and location selection, fully adapting to the cable routing requirements of the conductive component in different installation locations. Furthermore, the limiting structure of the blind holes is adapted to the conductive component requiring stable insertion and removal, while the through structure of the through holes is adapted to the conductive component requiring through-hole fixation, making it compatible with different types of electrotherapy device interfaces.

[0078] It should be noted that, in one embodiment, the conductive hole 122 may be a through hole, the conductive hole 122 may extend along the second direction D2, and the conductive hole 122 may penetrate through both ends of the first arched portion 12 along the second direction D2. All of the above are embodiments of this application and should not be construed as limiting this application.

[0079] Please refer to Figures 1 to 12 In one embodiment, the diameter of the conductive hole 122 is in the range of 1mm-2mm, and the radial dimension of the conductive element is greater than the radial dimension of the conductive hole 122.

[0080] It should be noted that the radial dimension of the conductive component is slightly larger than the radial dimension of the conductive hole 122, forming a slight interference fit. This is not a significant oversize, but rather a small difference, ensuring the ease of insertion and removal of the conductive component and the tightness of the connection. The slightly larger radial dimension of the conductive component allows for elastic compression between the conductive component and the wall of the conductive hole 122 after insertion, eliminating gaps and preventing the conductive component from wobbling within the conductive hole 122, thus ensuring the continuity of electrical signal transmission.

[0081] The diameter of the conductive hole 122 ranges from 1mm to 2mm, which can cover the metal rod specifications of most electrotherapy devices on the market. It can match general devices without customizing the conductive parts, thus improving the product compatibility of the electrode assembly 100.

[0082] Optionally, the diameter of the conductive hole 122 can be 1 mm, or 1.1 mm, or 1.2 mm, or 1.3 mm, or 1.4 mm, or 1.5 mm, or 1.6 mm, or 1.7 mm, or 1.8 mm, or 1.9 mm, or 2 mm, or other values ​​within the range of 1 mm to 2 mm. This application does not impose any restrictions on this.

[0083] In one embodiment, the protective cover 20 is tightly fitted to the electrode sheet 10 so that the protective cover 20 and the electrode sheet 10 are relatively fixed, thus preventing the electrode sheet 10 from falling off when the fixing member 200 is not inserted.

[0084] In one embodiment, the protective cover 20 and the electrode sheet 10 can also be connected by adhesive, that is, the outer periphery of the electrode sheet 10 or the inner wall of the protective cover 20 is provided with an adhesive to fix the protective cover 20 and the electrode sheet 10 by adhesive. This application does not limit this.

[0085] In one embodiment, the inner wall of the transverse opening 121 is provided with anti-slip texture or micro-protrusions to increase the friction between the fixing member 200 and the inner wall of the transverse opening 121, thereby further improving the stability of the electrode sheet 10.

[0086] Please refer to Figures 1 to 12 This application also provides an electrode fixing device, which includes a fixing member 200 and the electrode assembly 100, wherein the fixing member 200 passes through the transverse opening 121 of the first arched portion 12.

[0087] In the electrode fixing device provided in this application, the electrode 10 includes a body portion 11 and a first arched portion 12 protruding from the body portion 11. The first arched portion 12 has a transverse opening 121 and a conductive hole 122. The transverse opening 121 penetrates the first arched portion 12 along a first direction D1 and is used to pass through a fixing member 200. The conductive hole 122 is used to pass through a conductive member. The electrode 10 can be fixed by the fixing member 200. The electrode 10 has a long service life and does not need to be replaced frequently, significantly reducing the cost of use. Furthermore, the electrode 10 is fixed by the fixing member 200, which provides a flexible fixing method. It can be adapted to movable joints such as the wrist and knee, as well as planar areas such as the waist, abdomen, and shoulders, achieving electrotherapy adaptation for multiple areas of the whole body.

[0088] It should be noted that, in this embodiment, one fixing member 200 may correspond to one electrode plate assembly 100 or two electrode plate assemblies 100, and this application does not impose any restrictions on this.

[0089] In one embodiment, the fastener 200 includes a strap, specifically, the strap may be made of a single-sided or double-sided textured material, and may be used in conjunction with Velcro and connectors to achieve convenient fastening.

[0090] In one embodiment, the fixing member 200 includes an adhesive patch, specifically, the adhesive patch can be KT muscle glue material used in sports. The fixing member 200 is generally elongated, with the middle section covered (covering the main body of the electrode pad 10), and both ends of the fixing member 200 made into tearable covers, resembling a large band-aid. This structure of the fixing member 200 is low-cost, making the overall material cost of the electrode pad fixing device, when used with the electrode pad assembly 100, far lower than that of adhesive electrode pads in related technologies.

[0091] Please refer to Figures 1 to 12 This application also provides an electrotherapy device, an electrotherapy apparatus and an electrode fixing device, wherein the electrotherapy apparatus includes a conductive element and the conductive element passes through the conductive hole 122.

[0092] Optionally, the conductive element may include, but is not limited to, metal plugs and cables, and this application does not impose any restrictions on this.

The conductive hole 122 is used to pass through a conductive member. The electrode pad 10 can be fixed by the fixing member 200. The electrode pad 10 has a long service life and does not need to be replaced frequently, significantly reducing the cost of use. Furthermore, the electrode pad 10 is fixed by the fixing member 200, which provides a flexible fixing method. It can be adapted to movable joints such as the wrist and knee, as well as planar areas such as the waist, abdomen, and shoulders, achieving electrotherapy adaptation for multiple areas of the whole body and improving the versatility of the electrotherapy device.
