[0002] This utility model patent application claims priority to Chinese utility model patent application filed on September 20, 2024, with application number 202422299766.6 and invention title "Electrode Patch". Technical Field

[0003] This utility model relates to the field of medical electronic device technology, and in particular to an electrode pad and a physiotherapy patch. Background Technology

[0004] Electrode pads and therapeutic patches, as key components for bioelectrical signal transmission, are widely used in fields such as electrical stimulation therapy (e.g., TENS transcutaneous electrical nerve stimulation), physiological parameter monitoring (e.g., ECG electrocardiogram monitoring, EMG electromyography monitoring), and rehabilitation therapy. They are typically applied directly to the surface of the skin. Currently, most of these electrode pads or therapeutic patches are disposable, resulting in high waste and high user costs. Furthermore, because they are disposable, their disposal as waste after use pollutes the environment and increases urban waste disposal costs.

[0005] In addition, during the process of applying the physiotherapy patch to the human skin, the application position often needs to be slightly adjusted, and after the physiotherapy patch is applied to the human body, the electrode pad may be pulled by the human body's movement. For electrode pads with unstable structures, the above-mentioned pulling force may damage the electrical connection structure, causing the electrode pad to fail in subsequent functions.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0063] Implementation Method 1:

[0064] like Figures 1 to 4 , Figures 10 to 15 As shown, this utility model provides an electrode sheet 100, which includes a substrate layer, an electrode layer 103, a connecting terminal, and a first mounting portion 109. The substrate layer has a first end face 113 and a second end face 114 facing opposite directions. The electrode layer 103 is disposed on the second end face 114 of the substrate layer. The connecting terminal is disposed on the first end face 113 and is electrically connected to the electrode layer 103 via a conductive connector 104 disposed on the substrate layer. The conductive connector 104 can be mounted on the surface of the substrate layer, or at least a portion of the conductive connector 104 can be disposed within the substrate layer. The first mounting portion 109 is formed on the first end face 113 or the second end face 114 and is used to mount the electrode sheet 100 onto a suitable patch 201.

[0065] The electrode sheet 100 described in this utility model is designed as a reusable structure. It can be detachably mounted together with other components (disposable devices, such as patch 201) through the first mounting part 109. After use, the electrode sheet 100 can be disassembled and reused, saving usage costs and reducing the wear and tear of the electrode sheet 100.

[0066] The conductive connector 104 described in this utility model is disposed in the substrate layer and protected and fixed by the substrate layer, so that the conductive connector 104 is not easily damaged or disconnected when the electrode sheet 100 is adjusted or pulled, thereby ensuring that the structure of the electrode sheet 100 is not easily damaged, making the electrode sheet 100 more stable and more durable.

[0067] The following will describe in detail the specific structure of each part of the electrode sheet 100 of this utility model, as well as the position and connection relationship between each part.

[0068] like Figures 1 to 4 As shown, the electrode sheet 100 of this utility model includes a substrate layer, the substrate layer having a first end face 113 and a second end face 114 that are parallel and opposite to each other, wherein the first end face 113 is used to form a working surface (e.g., ...). Figure 1 As shown), the second end face 114 is used to form a mounting surface (e.g. Figure 2 (As shown).

[0069] A connection terminal is provided on the first end face 113 of the substrate layer for electrical connection with external electrical control equipment; an electrode layer 103 is provided on the second end face 114 of the substrate layer for direct contact with human skin; and the connection terminal and the electrode layer 103 are electrically connected through a conductive connector 104 disposed within the substrate layer. That is, the electrode layer 103 and the connection terminal are respectively disposed on opposite sides of the substrate layer, and are connected by the conductive connector 104; during use, the electrode layer 103 can be electrically connected to external electrical control equipment through the conductive connector 104, thereby ensuring the normal use of the electrode sheet 100.

[0070] Preferably, the conductive connector 104 is one of conductive fabric, conductive adhesive, conductive metal sheet, conductive metal wire, and conductive carbon cloth. The electrode layer 103 is one of metal film, conductive gel, conductive fabric, and conductive adhesive. The connecting terminal is one of metal snap fastener, metal magnetic snap fastener, and electrical socket; taking a metal snap fastener as an example, such as... Figure 3 As shown, it includes a nail holder 108 and a nail cover 107. The nail holder 108 and the nail cover 107 can clamp one end of the conductive connector 104 in the middle. The nail holder 108 passes through the conductive connector 104 and the substrate layer and is fastened together with the nail cover 107. An external electrical control device is provided with a connection device that can be adapted to the nail cover 107.

[0071] Preferably, the substrate layer and the electrode layer 103 can be fastened together by one of the following methods: adhesive 106, sewing, riveting, fastening, or pressing.

[0072] There are various types of electrode layers 103 disposed on the second end face 114 of the substrate layer. One or more independent electrode layers 103 may be disposed on the second end face 114.

[0073] like Figure 10 and Figure 11 As shown, this is an embodiment in which an electrode layer 103 is provided on a substrate layer. In this case, two electrode pieces 100 need to be attached to the human body during use. One electrode piece 100 is connected to an electrode on an external electronic control device, and the other electrode piece 100 is connected to another electrode on the external electronic control device. In this way, the two electrode pieces 100 can be connected to the human body to ensure the normal use of the electrode pieces 100.

[0074] like Figures 1 to 4 As shown, this is an embodiment where two electrode layers 103 are disposed on a substrate layer. Each electrode layer 103 is provided with a conductive connector 104 and a connecting terminal. The two electrode layers 103 are independent of each other, and the shape of the substrate layer can cover the two electrode layers 103, that is, the shape of the substrate layer matches the shape of the two separate electrode layers 103. In this case, only one electrode sheet 100 needs to be attached to the human body, and one electrode layer 103 of the electrode sheet 100 is connected to one electrode of an external electronic control device, and the other electrode layer 103 of the electrode sheet 100 is connected to another electrode of the external electronic control device. Thus, the electrode sheet 100 can achieve conductivity when attached to the human body, thereby ensuring the normal use of the electrode sheet 100.

[0075] Furthermore, when an electrode pad 100 has three or more mutually separated electrode layers 103, only one electrode pad 100 needs to be attached to the human body during use. At the same time, the electrode layers 103 on the electrode pad 100 used to connect different external electrodes are also insulated from each other. When the electrode pad 100 is connected to the electrode of an external electronic control device, at least one electrode layer 103 is connected to one electrode of the external electronic control device, and at least one electrode layer 103 is connected to another electrode of the external electronic control device. This ensures that the electrode pad 100 can conduct electricity through the human body, thereby ensuring the normal use of the electrode pad 100. For example, when an electrode sheet 100 is provided with three electrode layers 103, the three electrode layers 103 are set independently of each other, and one electrode layer 103 is connected to one electrode of an external electrical control device, and another electrode layer 103 is connected to another electrode of the external electrical control device. At this time, two of the electrode layers 103 on the electrode sheet 100 have been made conductive, and the remaining electrode layer 103 will be selected to be connected to any electrode of the external electrical control device according to the actual use requirements. The electrode layers 103 connected to the same electrode of the external electrical control device can be electrically connected through a conductive connector 104 or conventional electrical connection methods in the art.

[0076] Furthermore, when multiple electrode layers 103 are configured, the number of connection terminals can be selected based on the number of corresponding electrodes on the external control device. Therefore, one electrode layer 103 can correspond to one connection terminal, in which case multiple electrode layers 103 will have multiple corresponding connection terminals; of course, multiple electrode layers 103 can also be electrically connected to each other through one connection terminal (e.g., Figure 22 and Figure 23 As shown, it is used for electrical connection with an electrode on an external control device, which will not be described in detail here.

[0077] A first mounting portion 109 is provided on the first end face 113 or the second end face 114 of the substrate layer. The first mounting portion 109 can be one of a fastener, Velcro, magnetic adhesive, or double-sided adhesive. The electrode sheet 100 can be detachably mounted together with other components (disposable devices, such as the patch 201 described below) through the first mounting portion 109, thereby realizing the reusability of the electrode sheet 100.

[0078] like Figures 1 to 4 As shown, the first mounting portion 109 is disposed on the first end face 113 of the substrate layer, corresponding to the projected area of ​​the electrode layer 103. In this embodiment, since two electrode layers 103 are provided on the second end face 114 of the substrate layer, the substrate layer has an overall elongated structure. Therefore, at the positions corresponding to the two electrode layers 103, the first mounting portion 109 is formed on the first end face 113 of the substrate layer, thereby ensuring the stability of the connection between the electrode sheet 100 and other components. In some embodiments, the first mounting portion 109 can also be disposed on the first end face 113 around the circumference of the electrode layer 103 (not shown in the figure). That is, the placement area of ​​the first mounting portion 109 and the placement area of ​​the electrode layer 103 do not overlap in the projection direction. Under this structure, the flexibility of the placement area of ​​the first mounting portion 109 is better (it can be understood that in a stacked structure, the thinner the overall thickness of the structure, the better the flexibility). The first mounting portion 109 can be installed and used more stably. Of course, the placement area of ​​the first mounting portion 109 on the first end face 113 can be selected according to the actual connection needs, and there is no limitation here.

[0079] like Figures 12 to 15 As shown, the first mounting portion 109 is disposed on the second end face 114 of the substrate layer. In this embodiment, both the electrode layer 103 and the first mounting portion 109 are disposed on the second end face 114 of the substrate layer, and their positions need to be staggered. The first mounting portion 109 can be arranged circumferentially on the electrode layer 103, and the first mounting portion 109 can also be disposed between two electrode layers 103, thereby ensuring the stability of the connection between the electrode sheet 100 and other components. The area where the first mounting portion 109 is disposed on the second end face 114 can be selected according to the actual connection needs, and there is no limitation here.

[0080] Preferably, the substrate layer and the first mounting part 109 can be fastened together by one of the following methods: adhesive 106, sewing, riveting, fastening, or pressing.

[0081] The structure and technical effects of the preferred embodiment of the electrode sheet 100 of this utility model will be described in detail below.

[0082] According to one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the substrate layer includes a first substrate layer 101 and a second substrate layer 102 stacked together. The upper end surface of the first substrate layer 101 forms a first end surface 113, and the lower end surface of the second substrate layer 102 forms a second end surface 114. The conductive connector 104 is sandwiched and fixed between the first substrate layer 101 and the second substrate layer 102.

[0083] When the conductive connector 104 is disposed between the first substrate layer 101 and the second substrate layer 102, it can be jointly fixed by the first substrate layer 101 and the second substrate layer 102. This makes it less likely for the conductive connector 104 to be damaged or disconnected when the electrode sheet 100 is adjusted or pulled, thereby ensuring that the structure of the electrode sheet 100 is not easily damaged, making the electrode sheet 100 more stable and more durable.

[0084] Specifically, the first substrate layer 101 and the second substrate layer 102 have basically the same shape. They can be fastened together by adhesive 106, sewing, riveting, snapping, or pressing. The conductive connector 105 disposed between them can also be clamped and fixed between them in the above manner. The lower end face of the first substrate layer 101 is attached and fixed to the upper end face of the second substrate layer 102. The upper end face of the first substrate layer 101 forms a first end face 113, that is, the connecting terminal is disposed on the first substrate layer 101. The lower end face of the second substrate layer 102 forms a second end face 114, that is, the electrode layer 103 is fixed to the second substrate layer 102 by adhesive 106. The bonding method can be direct bonding or bonding under hot pressing with hot melt adhesive. There is no limitation here.

[0085] According to one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the conductive connector 104 has a first connecting end 111 and a second connecting end 112 spaced apart along its length. When the conductive connector 104 is disposed between the first substrate layer 101 and the second substrate layer 102, the first substrate layer 101 is provided with a mounting hole for the first connecting end 111 to be electrically connected to the connecting terminal, and the second substrate layer 102 is provided with a through hole for the second connecting end 112 to be electrically connected to the electrode layer 103.

[0086] Specifically, such as Figure 3 As shown, the connecting terminal is a metal snap fastener. The snap fastener's base 108 passes through the first connecting end 111 and the mounting hole on the first substrate layer 101 and is snapped together with the snap cover 107. The second connecting end 112 is electrically connected to the electrode layer 103 through the connector 105. The connector 105 is disposed in the through hole on the second substrate layer 102 and can be a conductive adhesive.

[0087] According to one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, a support pad layer 110 is provided on the side of the electrode layer 103 facing the substrate layer. The support pad layer 110 is used to elevate the electrode layer 103, so that the electrode layer 103 is more closely attached to the human skin.

[0088] Specifically, the support pad 110 can be disposed between any interlayer structure above the electrode layer 103, for example, it can be disposed between the second substrate layer 102 and the electrode layer 103, or it can be disposed between the connector 105 and the electrode layer 103 while ensuring electrical connection. In this embodiment, as... Figure 2 As shown, the support pad layer 110 is disposed between the second substrate layer 102 and the electrode layer 103. The support pad layer 110 and the second substrate layer 102 can be fastened together by one of the following methods: adhesive 106, sewing, riveting, fastening, or pressing. A portion of the electrode layer 103 is bonded to the support pad layer 110 by adhesive 106. The support pad layer 110 can be an elastomer, such as a sponge pad, silicone, latex, rubber, gel, etc., which has good flexibility to ensure user comfort.

[0089] Implementation Method Two:

[0090] like Figures 5 to 11 , Figures 16 to 21 As shown, this utility model also provides a physiotherapy patch 200, which includes a patch 201 and an electrode sheet 100 as described in Embodiment 1. A second mounting portion 203 adapted to the first mounting portion 109 is provided on one end face of the patch 201. The electrode sheet 100 can be detachably connected to the patch 201 through the first mounting portion 109 and the second mounting portion 203. The end face of the patch 201 facing the electrode layer 103 is an adhesive surface, which adheres the electrode sheet to the human skin. In some embodiments, the electrode sheet 100 can also be fixed to the user's physiotherapy site by providing binding elements (such as elastic bandages, elastic cloth, etc.) on the patch 201. Of course, one of the above methods can be selected, or they can be used simultaneously; no limitation is made here.

[0091] The physiotherapy patch 200 of this utility model adopts a split design. By setting up a reusable electrode sheet 100 and a disposable patch 201, the core components of the physiotherapy patch 200 are reused, saving usage costs and reducing the wear and tear of the electrode sheet 100.

[0092] The following will describe in detail the specific structure of each part of the physiotherapy patch 200 described in this utility model, as well as the position and connection relationship between each part.

[0093] The structure of electrode 100 has been described in detail above. The structure of patch 201 and the connection structure between patch 201 and electrode 100 will be described below.

[0094] The patch 201 can be made of medical adhesive tape with an adhesive surface. The second mounting part 203 and the first mounting part 109 are compatible, so both can be made of one of the following: fasteners, Velcro, magnetic tape, or double-sided tape.

[0095] like Figure 5 and Figure 6 As shown, in this embodiment, the second mounting part 203 is disposed on the lower end surface of the patch 201, and its mounting area is the same as that of the patch 201. Figures 1 to 4 The area corresponding to the first mounting portion 109 on the electrode sheet 100 shown in the diagram is such that the patch 201 in this embodiment is used to connect with the electrode sheet 100 on the first end face 113 of the first mounting portion 109. In this embodiment, the patch 201 and the electrode sheet 100 are stacked and connected vertically. In order to enable the connection terminals on the electrode sheet 100 to be smoothly connected to external electrical control equipment, the patch 201 is provided with mating holes 202 for the connection terminals to pass through; in this embodiment, the patch 201 is provided with two mating holes 202 corresponding to the two connection terminals on the electrode sheet 100. Figures 7 to 9 As shown, after the patch 201 and the electrode plate 100 are stacked and fixedly connected through the first mounting part 109 and the second mounting part 203, the two connecting terminals (metal fasteners) on the electrode plate 100 pass upward through the two mating holes 202 on the patch 201.

[0096] like Figure 16 and Figure 17 As shown, in this embodiment, the second mounting part 203 is disposed on the upper surface of the patch 201, and its mounting area is the same as that of the patch 201. Figures 12 to 15The area corresponding to the first mounting portion 109 on the electrode sheet 100 shown in the diagram is such that the patch 201 in this embodiment is used to connect with the electrode sheet 100 on the second end face 114 of the first mounting portion 109. In this embodiment, the electrode sheet 100 and the patch 201 are stacked and connected. In order to allow the electrode layer 103 on the electrode sheet 100 to make smooth contact with human skin, the patch 201 is provided with mating holes 202 for the electrode layer 103 to pass through; in this embodiment, the patch 201 is provided with two mating holes 202 corresponding to the two electrode layers 103 on the electrode sheet 100. Figures 19 to 21 As shown, after the patch 201 and the electrode sheet 100 are stacked and fixedly connected through the first mounting part 109 and the second mounting part 203, the two electrode layers 103 on the electrode sheet 100 pass downward through the two mating holes 202 on the patch 201.

[0097] The patch 201 and electrode pad 100 can be of any shape and size based on variations in their application location (such as the skin on the waist, face, abdomen, or any other location requiring massage, care, or treatment). Figure 8 , Figure 22 and Figure 23 As shown, this embodiment is for illustrative purposes only and is not intended to limit the shape and size of the patch 201 and electrode sheet 100 of this application. Furthermore, a protective layer 204 is provided on the adhesive surface of the patch 201, that is, the protective layer 204 is provided on the side of the electrode sheet 100 that is in contact with human skin (the adhesive surface), such as... Figure 6 and Figure 19 As shown, when the physiotherapy patch 200 is not in use, the protective layer 204 can protect the adhesive surface of the patch 201, thereby ensuring that the patch 201 has sufficient adhesion when the physiotherapy patch 200 is in use, so that the physiotherapy patch 200 can be better fixed on the human skin. The protective layer 204 is release paper, release film, etc. When the physiotherapy patch 200 needs to be used, the protective layer 204 is removed and the adhesive surface is applied to the human skin.
