Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electrode patch. Background Technology

[0002] When electrode patches are applied to human skin, the application position often needs to be adjusted slightly, and the electrode patches may be pulled by the movement of the human body after they are applied. For electrode patches with unstable structures, the above-mentioned pulling force may damage the electrical connection structure, causing the electrode patch to fail in subsequent functions. Summary of the Invention

[0003] The purpose of this application is to provide an electrode patch that solves the problem of electrode patches being easily damaged and not durable during use by adopting a multi-layered stable structure design.

[0004] The electrode patch of this application includes a first bonding layer, a second bonding layer, and at least one electrode sheet stacked together. The electrode sheet is electrically connected to an external electrical control device through a conductive connector, and the connector is fastened between the first bonding layer and the second bonding layer.

[0005] Based on the above structure, those skilled in the art have found that most of the reasons for electrode patch damage are due to poor structural stability, especially the wires used for electrical connections. These wires are often pulled during the use of the equipment, which often leads to loosening or damage at the relevant connection points in the electrode patch, thus affecting the normal use of the electrode patch. Therefore, this application sets two bonding layers to form a structure for fastening the connector, which greatly reduces the structural damage rate of the electrode patch due to pulling during use, making the electrode patch structure more stable and durable.

[0006] Furthermore, the connector has a first connecting end and a second connecting end along its length direction, and the second bonding layer is provided with a through hole for the first connecting end to be electrically connected to the electrode sheet. The first connecting end is tightly bonded to the electrode sheet under the action of the first bonding layer, and the second connecting end is electrically connected to an external electrical control device.

[0007] Based on the above structure, by covering the connector between the two bonding layers as much as possible, the stability of the connector's installation structure can be further ensured, while also preventing the exposed connector from being easily damaged by external factors.

[0008] Furthermore, a reinforcing part is provided at the through hole, which fastens the first connecting end to the electrode plate.

[0009] Furthermore, the reinforcing part and the bonding layer are an integral structure.

[0010] Based on the above structure, the reinforcement part can further ensure the tight connection between the connector and the electrode sheet, ensuring structural stability. Furthermore, the reinforcement part is directly made from the unseparated part of the second bonding layer, which not only makes the installation and use of the reinforcement part itself more convenient, but also avoids the introduction of more structural components, which would lead to a more complex electrode sheet structure and thus more potential structural instability. This ensures that the installation space of the connector is more compact.

[0011] Furthermore, mounting holes are provided on the first bonding layer for mounting external terminals, and the second connection end is electrically connected to an external electrical control device through the external terminals.

[0012] Furthermore, the connector includes a first connector and a second connector, the first connector and the second connector being at least partially overlapped, the first connector being electrically connected to the electrode sheet, and the second connector being electrically connected to the external terminal, or both the second connector and the first connector being electrically connected to the external terminal.

[0013] Furthermore, the external terminal is one of the following: a metal snap fastener, a metal magnetic snap fastener, or an electrical socket.

[0014] Based on the above structure, the use of connector one and connector two is to ensure that the relevant connection positions between the connector, electrode plate, and external terminal can make good contact and connection, and avoid the problem of unstable electrical signal transmission caused by poor contact. In addition, through the structural design of the external terminal, it is ensured that connector one and connector two and their related connection positions are all firmly fixed between adhesive layer one and adhesive layer two. That is, a firm installation space is also a connection protection space, which is not easy to be pulled and cause damage to the electrode plate structure during subsequent use.

[0015] Furthermore, the connector is one of conductive fabric, conductive adhesive, conductive metal sheet, conductive metal wire, and conductive carbon cloth. These conductive connectors have good flexibility and do not require much installation space, which makes the overall electrode patch structure thin, light, simple, and easy to use.

[0016] Furthermore, the first and second adhesive layers are adhesive tapes, and the first adhesive layer, the connector, the second adhesive layer, and the electrode sheet are all fastened together by one of the following methods: adhesive, sewing, riveting, fastening, or pressing.

[0017] Preferably, the side of the first bonding layer that bonds to the second bonding layer has an insulating adhesive, and the mounting surface of the connector has a conductive adhesive.

[0018] Based on the above structure, the first bonding layer, the connector, the second bonding layer, and the electrode sheet are all fastened together with adhesive. The first bonding layer and the second bonding layer are constructed as elastic adhesive tape, and the adhesive on them is an insulating adhesive that does not conduct electricity, thus preventing multiple electrode sheets from forming a conductive path. The adhesive used on the connector is a conductive adhesive, which ensures both the tightness of the connection and the electrical connectivity of the relevant positions.

[0019] Furthermore, the first bonding layer and / or the second bonding layer have cuts extending through their thickness direction.

[0020] Furthermore, when there are at least two electrode sheets, the cut is located between the projected areas of adjacent electrode sheets.

[0021] Based on the above structure, the design of the cut can disperse the pulling force of the electrode patch during use, and prevent the electrode patch from being not firmly attached to the human skin or from separating from the human skin in some places due to human movement / movement, thereby affecting the effect of the electrode patch, so that the electrode patch can fit the human skin more closely.

[0022] Furthermore, curved portions are symmetrically provided in the width direction of the first and / or second adhesive layers. The curved portion structure on the patch allows the electrode patch to have further deformation as the skin deforms under the movement or action of the human body when it is applied to the human body, so as to further ensure good adhesion between the electrode patch and the human body during use.

[0023] Furthermore, the electrode patch also includes a protective layer, which corresponds to the size and shape of the second adhesive layer and is disposed on the side of the electrode patch that adheres to the human skin. Specifically, the protective layer is release paper or release plastic film. The protective layer can protect the adhesive surface of the electrode patch to the human skin when the electrode patch is not in use, and it is also easy to store. The protective layer can be peeled off when needed.

[0024] In summary, the electrode patches provided in the various embodiments of this application, by employing a multi-layered adhesive sheet structure, encapsulate the connectors that are prone to structural damage and thus electrode patch failure, as well as the connection positions between them and the electrode sheet and / or external terminals, within the layered structure of the adhesive sheet. This achieves secure installation and electrical connectivity between the various structures, making the electrode patches less susceptible to damage or failure due to external forces. During the research and development process, relevant personnel further discovered that the design of the cuts and curved sections ensures that when the electrode patches are applied to human skin, they will not separate from or detach from the skin due to pulling forces during human movement or actions. The cuts and curved sections can disperse / buffer the pulling forces, ensuring that the electrode patches always adhere tightly to the human skin and guaranteeing the effectiveness of the electrode patches.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following is for reference. Figures 1-3 The electrode patch 10 according to an embodiment of the present invention is described.

[0034] like Figures 1-3 As shown, the electrode patch 10 according to an embodiment of the present invention includes a first bonding layer 13, a second bonding layer 12 and at least one electrode sheet 20 stacked together. The electrode sheet 20 is electrically connected to an external electrical control device through a conductive connector. The connector is fastened between the first bonding layer 13 and the second bonding layer 12. In actual use, the side with the electrode sheet 20 is attached to the human skin.

[0035] It should be noted that the electrode patch 20 is disposed on the side of the second bonding layer 12 away from the first bonding layer 13, while the connector is disposed between the first bonding layer 13 and the second bonding layer 12. In this way, after the electrode patch 20 is connected to the connector, it can be electrically connected to the external electrical control equipment through the connector, thereby ensuring the normal use of the electrode patch 10.

[0036] Furthermore, when the connector is placed between the first adhesive layer 13 and the second adhesive layer 12, it can be fixed together by the first adhesive layer 13 and the second adhesive layer 12. This makes it less likely for the connector to be damaged or disconnected from the electrode sheet 20 when the electrode patch 10 is adjusted or pulled, thus ensuring that the structure of the electrode patch 10 is not easily damaged. This makes the electrode patch 10 more stable and more durable.

[0037] There are several scenarios when electrode pads 20 are disposed on electrode patches 10. When one electrode patch 10 has one electrode pad 20, two electrode patches 10 need to be attached to the human body during use. One electrode patch 10 is connected to the positive terminal of the external electrical control device, and the other electrode patch 10 is connected to the negative terminal of the external electrical control device. In this way, the two electrode patches 10 can conduct electricity when attached to the human body, thus ensuring the normal use of the electrode patch 10. When one electrode patch 10 has two electrode pads 20, only one electrode patch 10 needs to be attached to the human body during use. The two electrode pads 20 are insulated from each other, and one electrode pad 20 is connected to the positive terminal of the external electrical control device, and the other electrode pad 20 is connected to the negative terminal of the external electrical control device. In this way, the two electrode pads 20 can conduct electricity through the human body, thus ensuring the normal use of the electrode patch 10.

[0038] Furthermore, when an electrode patch 10 is provided with three or more electrode pieces 20, only one electrode patch 10 needs to be attached to the human body during use. At the same time, the multiple electrode pieces 20 on the electrode patch 10 are also insulated from each other. When the multiple electrode pieces 20 are connected to an external electrical control device, at least one electrode piece 20 is connected to the positive terminal of the external electrical control device, and at least one electrode piece 20 is connected to the negative terminal of the external electrical control device. This ensures that the electrode pieces 20 can conduct through the human body, thereby ensuring the normal use of the electrode patch 10. For example, when an electrode patch 10 is provided with three electrode pieces 20, the three electrode pieces 20 are insulated from each other, and one electrode piece 20 is connected to the positive terminal of the external electrical control device, and one electrode piece 20 is connected to the negative terminal of the external electrical control device. At this time, two electrode pieces 20 have already achieved conduction. The remaining electrode piece 20 will be selectively connected to the positive or negative terminal of the external electrical control device according to the actual use requirements.

[0039] In some embodiments, such as Figure 2 As shown, the connector has a first connecting end and a second connecting end along its length direction. The second bonding layer 12 is provided with a through hole 122 for the first connecting end to be electrically connected to the electrode sheet 20. The first connecting end is tightly bonded to the electrode sheet 20 under the action of the first bonding layer 13, and the second connecting end is electrically connected to an external electrical control device.

[0040] It should be noted that when the electrode pad 20 is disposed on the side of the second adhesive layer 12 away from the first adhesive layer 13, the first connecting end can pass through the through hole 122 provided on the second adhesive layer 12 and connect to the electrode pad 20. At the same time, the second connecting end of the connector is electrically connected to the external electrical control device. At this time, the second connecting end can extend out of the side where the first adhesive layer 13 and the second adhesive layer 12 are combined and connect to the external electrical control device. The second connecting end can also pass through the thickness direction of the first adhesive layer 13 and connect to the external electrical control device, thereby ensuring that the electrode pad 20 can receive a stable power supply. The connection between the first connecting end and the electrode pad 20 can be kept fixed under the action of the first adhesive layer 13, thereby ensuring that the electrode pad 20 is not easily disconnected from the connector when the electrode pad 10 is adjusted in position or subjected to a pulling force (the pulling effect caused by the expansion and contraction of the skin during human movement / exercise).

[0041] For example, when a through hole 122 is provided on the second bonding layer 12, the size of the through hole 122 matches the size of the first connecting end of the connector. This makes the gap between the first connecting end and the through hole 122 smaller when the connector is placed between the first bonding layer 13 and the second bonding layer 12, resulting in a more compact structure. This makes the first bonding layer 13 better fix the first connecting end when it is bonded to the second bonding layer 12. That is, after the first bonding layer 13 is bonded, the first connecting end has less deformation or movement space when the electrode patch 10 is subjected to force, which makes it less likely for the connector to break off from the electrode patch 20. Meanwhile, the connector is located between the first bonding layer 13 and the second bonding layer 12. That is, after the electrode patch 10 is assembled, the connector will be located inside the electrode patch 10. This avoids the connector being exposed to the outside world, thereby preventing the connector from being damaged by the outside world and ensuring the normal use of the electrode patch 10. At the same time, the connector being located between the first bonding layer 13 and the second bonding layer 12 can also avoid the risk of leakage of the electrode patch 10. That is, the external electrical control equipment sends current into the human body through the connecting terminal 50, the connector and the electrode 20. The connecting terminal 50 is located on the side away from the human body, the connector is located between the first bonding layer 13 and the second bonding layer 12, and the electrode 20 is in contact with the human body. In this way, only the discharge end of the electrode patch 10 is in contact with the human body, and the connector, as a current conducting component, is not in contact with the human body, thereby avoiding the risk of leakage.

[0042] In some embodiments, such as Figure 2 As shown, a reinforcing part 121 is also provided corresponding to the through hole 122, and the reinforcing part 121 fastens the first connecting end to the electrode plate 20.

[0043] It should be noted that when the first connecting end of the connector is located at the through hole 122, the side of the first connecting end facing the second adhesive layer 12 will be connected to the electrode sheet 20, while the side of the first connecting end away from the second adhesive layer 12 will be connected to the reinforcing part 121. This allows the first connecting end to be better secured to the electrode sheet 20, so that the connection between the electrode sheet 20 and the connector will not be broken when the electrode patch 10 is adjusted.

[0044] For example, after the first connecting end is connected to the electrode sheet 20, the reinforcing part 121 will first cover the first connecting end, and the bonding layer 13 will then cover the reinforcing part 121, thereby making the connection between the electrode sheet 20 and the connector more stable, and thus ensuring that the electrode sheet 20 and the connector are not easily disconnected when the electrode patch 10 is adjusted.

[0045] The reinforcing part 121 can be constructed as an independent adhesive layer. After the first connecting end is connected to the electrode sheet 20, the reinforcing part 121 will be bonded to the side of the connecting sheet away from the electrode sheet. In addition, part of the reinforcing part 121 will also be connected to the second adhesive layer 12, thereby ensuring the reinforcing effect of the reinforcing part 121 on the connecting sheet. At the same time, the shape of the reinforcing part 121 can be adjusted according to the actual use. That is, the reinforcing part 121 can be constructed as a strip or a circle, which will not be elaborated here.

[0046] Furthermore, the reinforcing part 121 can also be constructed in other forms. For example, the edge of the reinforcing part 121 is formed with a protrusion, and the edge of the through hole 122 of the patch layer 2 is formed with a groove that matches the protrusion. In this way, after the reinforcing part 121 is connected to the connecting piece 1, the reinforcing part 121 and the patch layer 2 are engaged, thereby making the reinforcing part 121 more stable.

[0047] In some embodiments, such as Figure 2 As shown, the reinforcing part 121 and the second adhesive layer 12 are an integral structure. That is, the reinforcing part 121 is at least partially connected to the second adhesive layer 12, meaning that the reinforcing part 121 itself is a part of the second adhesive layer 12. This eliminates the need for additional connecting components between the reinforcing part 121 and the second adhesive layer 12, ensuring the structural stability between them. Furthermore, it allows the reinforcing part 121 to secure the first connecting end while occupying less installation space between the first adhesive layer 13 and the second adhesive layer 12. This results in a tighter fit between the connector and the electrode sheet 20 when the connector is positioned between the first adhesive layer 13 and the second adhesive layer 12, leading to a more stable connection between the connector and the electrode sheet 20.

[0048] For example, when the reinforcing part 121 and the second adhesive layer 12 are an integral structure, the reinforcing part 121 can be cut on the second adhesive layer 12 at the through hole 122 in the shape of the first connecting end or close to the shape of the first connecting end, and a portion is left uncut, such as... Figure 2 As shown, after forming the through hole 122, the part of the bonding layer 12 that needs to be discharged is constructed as the reinforcement part 121, so that no new structural elements are introduced into the bonding layer 12, thereby making the structure of the electrode patch 10 simpler. This makes the electrode patch 10 itself have good structural stability. At the same time, the reinforcement part 121 is the unseparated part of the bonding layer 12, which also makes the installation of the reinforcement part 121 easier.

[0049] Furthermore, during the assembly of the electrode patch 10, the axisymmetric center of the electrode sheet 20 is aligned with the through hole 122 of the second bonding layer 12 and bonded to the second bonding layer 12. A connector is placed on the side of the second bonding layer 12 away from the electrode sheet 20. When the first connecting end of the connector is connected to the electrode sheet 20 through the through hole 122, the reinforcing part 121 is first lifted up. After the first connecting end is fixed, the reinforcing part 121 is then placed on top of it. After the reinforcing part 121 is fixed, the first bonding layer 13 is placed on top of the second bonding layer 12, thereby wrapping the connector between the two. In this way, the first bonding layer 13 is connected to the reinforcing part 121 and the rest of the connector, thereby achieving further fixation of the connector.

[0050] The first connecting end of the connector is double-fixed by the reinforcement part 121 and the bonding layer 13, which makes the connection between the connector and the electrode plate 20 more stable, and makes it less likely for the connector and the electrode plate 20 to break when the electrode patch 10 is adjusted or subjected to tensile force.

[0051] In some embodiments, such as Figure 2 As shown, mounting holes 131 are provided on the bonding layer 13 for mounting external terminals 50, and the second connection end is electrically connected to external electrical control equipment through the external terminals 50.

[0052] It should be noted that the mounting hole 131 provided on the first bonding layer 13 can be used to install the external terminal 50. After the second connecting end of the connector is connected to the external terminal 50, the external electrical control equipment can be connected to the external terminal 50 and supply power to the electrode plate 20 through the connector. In this way, the entire connector can be placed between the first bonding layer 13 and the second bonding layer 12, thereby reducing the contact between the connector and the outside world, protecting the connector from external damage, and avoiding the risk of leakage, thus making the electrode plate 10 safer.

[0053] Specifically, the external terminal 50 is one of the following: a metal snap fastener, a metal magnetic snap fastener, or an electrical connector. It should be noted that the external terminal 50 is one of the aforementioned interfaces. This makes it easier to connect the external electrical control device to the external terminal 50 after the external terminal 50 is connected to the second connecting end of the connector, thus making the use of the electrode patch 10 more convenient. Furthermore, after the external terminal 50 is connected to the second connecting end, it can further secure the connector, making the connection between the connector and the bonding layer 13 more stable. This also prevents the connector from easily disconnecting from the external terminal 50 when the electrode patch 10 is adjusted.

[0054] When the external terminal 50 further fixes the connector, it is understood that the external terminal 50 includes an external connector and an internal fixing component. The external connector is used to connect to an external electrical control device, and the internal fixing component is used to fix the external connector to the bonding layer 13. When the internal fixing component fixes the external connector, the internal fixing component and the external connector are located at the mounting hole 131 of the bonding layer 13 and on both sides of the bonding layer 13. At the same time, the second connecting end of the connector is located between the internal fixing component and the bonding layer 13. Thus, after the internal fixing component and the external connector are connected, the second connecting end will be sandwiched between the internal fixing component and the external connector, thereby enabling the external terminal 50 to further fix the connector.

[0055] In some embodiments, such as Figure 2 As shown, the connector includes a first connector 30 and a second connector 40. The first connector 30 and the second connector 40 are at least partially overlapped. The first connector 30 is electrically connected to the electrode sheet 20, and the second connector 40 is electrically connected to the external terminal 50. Alternatively, both the second connector 40 and the first connector 30 are electrically connected to the external terminal 50. Connector 30 is electrically connected to electrode 20, and connector 40 is electrically connected to external terminal 50. Connector 30 and connector 40 overlap at least partially, allowing them to conduct electricity. This enables external electrical control equipment to provide electrical signals to electrode 20 through the connectors. Furthermore, the use of connectors 30 and 40 ensures the stability of the connection between the connectors, electrode 20, and external terminal 50, preventing unstable electrical signal transmission due to poor contact. In other words, when both connector 40 and connector 30 are electrically connected to external terminal 50, connector 40 plays an auxiliary role in transmission, making the electrical signal transmission between external terminal 50 and electrode 20 more stable.

[0056] For example, when connector 30 is electrically connected to electrode 20 and connector 40 is electrically connected to external terminal 50, and connector 30 and connector 40 only partially overlap, when external terminal 50 is not connected to connector 30, the current flow when the external electrical control device supplies power to electrode 20 is from external terminal 50 to connector 40, from connector 40 to connector 30, and from connector 30 to electrode 20. That is, the partial overlap of connector 30 and connector 40 enables the conduction between external terminal 50 and electrode 20. By setting connector 30 and connector 40, the connection between connector, electrode 20 and external terminal 50 is made more stable, thereby avoiding unstable electrical signal transmission caused by poor contact.

[0057] For example, when connector 30 and connector 40 overlap completely, both connector 40 and connector 30 can be electrically connected to external terminal 50. This allows external electrical control equipment to supply power to electrode 20 in the order of external terminal 50, connector 30, and electrode 20. The overlap of connector 40 and connector 30 enables connector 40 to simultaneously assist in the connection between external terminal 50 and electrode 20, thereby making the signal transmission and power supply between external terminal 50 and electrode 20 more stable.

[0058] In the above example, when the connector includes connector 30 and connector 40, the external terminal 50, which is configured as a metal magnetic snap fastener, is connected to connector 40. When the second connection end of connector 40 overlaps with the second connection end of connector 30, the metal magnetic snap fastener can conduct electricity with connector 30, thereby making the electrical signal transmission between electrode 20, connector and external terminal 50 more stable.

[0059] Furthermore, in other embodiments, the external terminal 50 can achieve the above effects using other interface forms, which will not be described in detail in this application.

[0060] Of course, more connectors can be provided between the first bonding layer 13 and the second bonding layer 12, so that there is sufficient redundancy in the conduction between the electrode sheet 20 and the external terminal 50, thereby making the electrical signal transmission between the electrode sheet 20, the connector and the external terminal 50 more stable, thus ensuring the normal use of the electrode patch 10.

[0061] When the connector includes connector 30 and connector 40, both connector 30 and connector 40 are located between adhesive layer 13 and adhesive layer 12. That is, both connector 30 and connector 40 can be fixed by adhesive layer 13 and adhesive layer 12. This ensures that the overlapping part of connector 30 and connector 40 can remain conductive, thereby preventing the electrode 20 from being easily disconnected from the external terminal 50 when the electrode patch 10 is adjusted.

[0062] In some embodiments, the connector is one of conductive fabric, conductive adhesive, conductive metal sheet, conductive metal wire, and conductive carbon cloth. This gives the connector a certain degree of flexibility, allowing it to deform with the electrode patch 10 during use, maintaining a tighter fit with human skin and making it less prone to damage, thus ensuring the normal use of the electrode patch 10.

[0063] In some embodiments, the first adhesive layer 13, the connector, the second adhesive layer 12, and the electrode sheet 20 are all fastened together by one of the following methods: adhesive, sewing, riveting, snap-fitting, or pressing. This ensures a more stable connection between the first adhesive layer 13, the connector, the second adhesive layer 12, and the electrode sheet 20. This allows the connector to be protected by the first adhesive layer 13 and the second adhesive layer 12 during use, and prevents the electrode sheet 20 from easily detaching from the second adhesive layer 12. Simultaneously, the connector is located between the first adhesive layer 13 and the second adhesive layer 12, thus preventing contact with the outside environment and reducing the risk of damage and leakage.

[0064] In some embodiments, the first adhesive layer 13 and the second adhesive layer 12 are adhesive tape, which allows the electrode patch 10 to have a certain deformation after the first adhesive layer and the second adhesive layer 12 are bonded together, thereby allowing the electrode patch 10 to better conform to the human body. The first adhesive layer 13 and the second adhesive layer 12 can be made of elastic adhesive tape, or they can be made of non-woven fabric with adhesive. That is, using materials that are inherently adhesive and can adhere to each other and be fixed to the human body can achieve the above-mentioned purpose. Preferably, in this embodiment, the first adhesive layer 13 and the second adhesive layer 12 can be made of elastic adhesive tape, which allows the first adhesive layer 13 and the second adhesive layer 12 to have a certain deformation, thereby allowing the electrode patch 20 to better conform to the human body.

[0065] For example, the connector is constructed of conductive fabric, and the first adhesive layer 13 and the second adhesive layer 12 are constructed of elastic adhesive tape. The first adhesive layer 13, the connector, the second adhesive layer 12, and the electrode sheet 20 are fastened together with adhesive. In this way, the connector itself has a certain degree of flexibility, and the connector requires less installation space. This makes the assembled electrode sheet 10 lightweight and easy to use. At the same time, the first adhesive layer 13 and the second adhesive layer 12 are constructed of elastic adhesive tape, which gives the assembled electrode sheet 10 a certain deformation space, so that the electrode sheet 10 can better fit the human body. The first adhesive layer 13, the connector, the second adhesive layer 12, and the electrode sheet 20 are connected by adhesive, which makes the assembly process of the electrode sheet 10 simpler, and at the same time ensures the connection stability between the electrode sheet 20, the connector, and the external terminal 50.

[0066] In some embodiments, the side of the first adhesive layer 13 that is bonded to the second adhesive layer 12 has an insulating adhesive.

[0067] It should be noted that the adhesive used when bonding layer 13 and bonding layer 12 are bonded is an insulating adhesive. This ensures that the parts of the electrode patch 10 that are not connected to the electrode sheet 20 and the external terminal 50 are insulated. This allows the electrode sheets 20 to be insulated from each other when multiple electrode sheets 20 are provided on the electrode patch 10, thereby avoiding mutual interference between multiple electrode sheets 20.

[0068] In this embodiment, the electrode patch 10 conducts current into the human body by discharging through the electrode pads 20 attached to the human body. The electrode patch 10 is provided with two electrode pads 20, one of which is connected to the positive electrode and the other to the negative electrode. When the two electrode pads 10 are energized, the current can flow through the human body to achieve conductivity, thus enabling the electrode patch 20 to operate normally. However, if the two electrode pads 20 are connected within the first adhesive layer 13 and the second adhesive layer 12, no current will flow through the human body when the electrode patch 10 is energized, which will cause the electrode patch 10 to fail.

[0069] For example, when the electrode patch 10 is provided with two electrode pieces 20, the two electrode pieces 20 are symmetrically arranged at both ends in the length direction of the first adhesive layer 13 and the second adhesive layer 12, and a cut 60 is provided between the areas of the two electrode pieces 20 projected onto the first adhesive layer 13 and the second adhesive layer 12. In this way, there is less communication between the two electrodes 20. At the same time, there is also an insulating adhesive between the first adhesive layer 13 and the second adhesive layer 12. This ensures that the two electrode pieces 20 do not conduct between the first adhesive layer 13 and the second adhesive layer 12, thereby ensuring the normal use of the electrode patch 10.

[0070] Alternatively, insulating adhesive can be applied to the side of the second adhesive layer 12 that is bonded to the first adhesive layer 13. This allows the connector to be fixed by the second adhesive layer 12 after it is applied to the second adhesive layer 12, and the second adhesive layer 12 and the first adhesive layer 13 can also be fixed together. Alternatively, insulating adhesive can be applied to both sides of the second adhesive layer 12 and the first adhesive layer 13 that are bonded together. This allows the first adhesive layer 13 and the second adhesive layer 12 to be better fixed together after they are bonded together, thus ensuring that the electrode patch 10 can be used normally when it is applied to the human body.

[0071] In some embodiments, the mounting surface of the connector is provided with conductive adhesive.

[0072] It should be noted that when the mounting surface of the connector has conductive adhesive, the connector can be made conductive when connected to the electrode plate 20 and the external terminal 50, thus ensuring the normal use of the electrode patch 10. Furthermore, when the connector includes connector 1 30 and connector 2 40, conductive adhesive is also present at the overlapping part of connector 1 30 and connector 2 40, so that the overlapping part of connector 1 30 and connector 2 40 can be made conductive, thus ensuring the conductivity between the electrode plate 20 and the external terminal 50, and thus ensuring the normal use of the electrode patch 10.

[0073] For example, on the bonding layer 13, an insulating adhesive is provided on the side that is bonded to the bonding layer 12, and a conductive structural adhesive is provided on the mounting surface of the connector. In this way, after the bonding layer 13 and the bonding layer 12 are bonded together, the area where the connector is not provided can be insulated, thereby preventing multiple electrode pieces 20 from becoming conductive and thus preventing mutual interference between multiple electrode pieces 20. At the same time, the conductive adhesive on the mounting surface of the connector can ensure the conductivity between the electrode piece 20, the connector and the external terminal 50, thereby ensuring the normal use of the electrode patch 10.

[0074] In some embodiments, such as Figures 1-3 As shown, the first adhesive layer 13 has a cut 60 extending through its thickness direction. This cut 60 on the first adhesive layer 13 can disperse the stress of the electrode patch 10 and prevent the electrode patch 10 from wrinkling when moved or subjected to tensile forces. In some embodiments, the second adhesive layer 12 has a cut 60 extending through its thickness direction. This cut 60 on the second adhesive layer 12 can disperse the stress of the electrode patch 10 and prevent the electrode patch 10 from wrinkling when moved or subjected to tensile forces.

[0075] In some embodiments, the first adhesive layer 13 and the second adhesive layer 12 have cutouts 60 extending through their thickness direction. The cutouts 60 on the first adhesive layer 13 and the second adhesive layer 12 can disperse the stress on the electrode patch 10 and make the electrode patch 10 less prone to wrinkling when it moves or is subjected to tensile forces.

[0076] Preferably, in this embodiment, both the first bonding layer 13 and the second bonding layer 12 have slits 60 extending through their thickness direction, which can better disperse the stress on the electrode patch 10 and make the electrode patch less prone to wrinkling when it moves or is subjected to tensile force.

[0077] For example, when a slit 60 is formed in the thickness direction of the first adhesive layer 13 or the second adhesive layer 12, the slit 60 can disperse the tensile force that occurs during the use of the electrode patch 10, making it less likely for the electrode patch 10 to separate from the human skin, thus making the electrode patch 10 more firmly fixed on the human body. Preferably, in this embodiment, both the first adhesive layer 13 and the second adhesive layer 12 are provided with slits 60, and the slits 60 on the first adhesive layer 13 and the second adhesive layer 12 overlap. After the first adhesive layer 13 and the second adhesive layer 12 are attached, the two slits 60 can face each other. The two overlapping slits 60 can better disperse the tensile force that occurs during the use of the electrode patch 10, thereby avoiding the formation of wrinkles. At the same time, the slits 60 in the first adhesive layer 13 and the second adhesive layer 12 can disperse the stress of the electrode patch 10 itself, so that the electrode patch 10 does not wrinkle when attached to the human body. In this embodiment, when there are at least two electrode sheets 20, the cut 60 is located between the projected areas of adjacent electrode sheets 20.

[0078] Furthermore, such as Figures 1-3 As shown, when two electrode pads 20 are provided, a cut 60 is formed on the electrode patch 10. The cut 60 is located between the projected areas of the two electrode pads 20. The cut 60 is formed in the thickness direction of the first adhesive layer 13 and the second adhesive layer 12. The projected areas of the two electrode pads 20 can be understood as the areas of the two electrode pads 20 projected onto the first adhesive layer 13 and the second adhesive layer 12. By limiting the cut 60 between the two areas, the two electrode pads 20 can provide positioning for the cut 60. Furthermore, by opening the cut 60 between the two electrode pads 20, the cut 60 can better disperse the tensile force generated by the electrode patch 10 during use, thereby allowing the electrode patch 10 to be better fixed to the human body.

[0079] It should be noted that multiple cuts 60 can be formed between the two electrode patches 20. That is, there may not be only one cut 60 between the two electrode patches 20 and the projected area of ​​the first adhesive layer 13 and the second adhesive layer 12. By setting multiple cuts 60, the electrode patch 10 can better disperse the pulling force during use, thereby enabling the electrode patch 10 to better adhere to the human body.

[0080] For example, in other embodiments, more electrode pads 20 can be provided. For instance, when three electrode pads 20 are provided, at least two cuts 60 are formed on the electrode patch 10, that is, at least one cut 60 is formed between the projected areas of two adjacent electrode pads 20 on the first adhesive layer 13 and the second adhesive layer 12. This ensures that the electrode patch 10 can better adhere to the human body during use.

[0081] In some embodiments, curved portions 70 are symmetrically provided in the width direction of the first adhesive layer 13 and / or the second adhesive layer 12. For example... Figures 1-3 As shown, curved portions 70 are symmetrically provided in the width direction of the first adhesive layer 13 or the second adhesive layer 12. This makes it less likely for the electrode patch 10 to wrinkle when it is attached to the human body. At the same time, when the human body moves or the skin deforms under the action of movement, the electrode patch 10 can also deform to a certain extent, thus making it less likely for the electrode patch 10 to wrinkle when attached to the human body. This ensures that the electrode patch 10 can maintain a good fit with the human body and thus ensures the effectiveness of the electrode patch 10 in use. Alternatively, curved portions 70 are symmetrically provided in the width direction of the first bonding layer 13 and the second bonding layer 12. After the first bonding layer 13 and the second bonding layer 12 are bonded together, the electrode patch 10 has symmetrical curved portions 70 in the width direction. This makes the electrode patch 10 less prone to wrinkling when it is applied to the human body, allowing the electrode patch 10 to fully adhere to the human body. Furthermore, the electrode patch 10 is less prone to wrinkling when the human body moves or when the skin is stretched. This ensures that the electrode patch 10 can fully adhere to the human body during use, thereby enabling the electrode patch 10 to produce sufficient effect during operation.

[0082] For example, both the first adhesive layer 13 and the second adhesive layer 12 are symmetrically provided with curved portions 70 in the width direction. This makes it less likely for wrinkles to appear at the curved portions 70 when the electrode patch 10 is applied to the human body. At the same time, when the human body moves or the skin deforms during movement, the electrode patch 10 can also deform to a certain extent. This makes it less likely for the electrode patch 10 to wrinkle and also makes it less likely for the electrode patch 10 to fall off the human body. This ensures that the electrode patch 10 is fixed more firmly, thus ensuring the effectiveness of the electrode patch 10 in use.

[0083] In some embodiments, the electrode patch 10 further includes a protective layer 11, which corresponds to the size and shape of the second adhesive layer 12 and is disposed on the side of the electrode patch 10 that adheres to human skin, such as... Figure 2 As shown, when the electrode patch 10 is not in use, the protective layer 11 can protect the adhesive on the electrode patch 10, thereby ensuring that the electrode patch 10 has sufficient adhesion when in use, so that the electrode patch 10 can be better fixed on the human body.
