Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a physiotherapy device. Background Technology

[0002] Electrotherapy involves connecting pulsed electrical signals of a specific voltage and frequency to the human body through electrodes. Since many components of human tissue possess certain electrical properties, when stimulated electrically, the body's muscles, nerves, body fluids, and blood will produce a certain degree of physiochemical reaction. Low-frequency and medium-frequency electrotherapy devices are among the most common types of such physiotherapy equipment.

[0003] The electrode section and the main body of a physiotherapy device are usually two separate products. During use, the electrode section needs to be electrically connected to the main body to apply pulsed current to the electrode section via the main body. Related technologies involve wires on the electrode section and connectors on the main body, where the wires are inserted to connect the electrode section to the main body. The wires between the electrode section and the main body make the physiotherapy device messy and cumbersome to use. Utility Model Content

[0004] This application provides a physiotherapy device that simplifies the connection process between the electrode assembly and the main body of the device, thereby improving the ease of use of the physiotherapy device.

[0005] The physiotherapy device provided in this application includes: a device body and an electrode assembly; wherein, the device body has a corresponding first conductive element and a first connecting structure, and the device body can be worn on the user's limb; the electrode assembly has a second conductive element that matches the first conductive element, and the electrode assembly also has a second connecting structure that matches the first connecting structure, the second connecting structure cooperating with the first connecting structure to detachably connect the electrode assembly to the device body; when the second connecting structure is connected to the first connecting structure, the second conductive element abuts against the first conductive element to electrically connect the electrode assembly to the device body.

[0006] The physiotherapy device provided in this application features a first connecting structure on the main body and a second connecting structure on the electrode assembly. Both the first and second connecting structures are detachable, facilitating the assembly and connection of the electrode assembly to the main body, and also enabling easy disassembly and separation. Simultaneously, the main body has a first conductive element corresponding to the first connecting structure, and the electrode assembly has a second conductive element matching the first conductive element. Thus, during the assembly and connection of the electrode assembly to the main body via the second and first connecting structures, the second conductive element abuts against the first conductive element, thereby electrically connecting the electrode assembly to the main body. Compared to related technologies that electrically connect the electrode assembly to the main body via wires, the physiotherapy device provided in this application allows for automatic electrical connection between the electrode assembly and the main body during assembly, without any extending wires between them. Therefore, the physiotherapy device provided in this application simplifies the connection process between the electrode assembly and the main body, improving the ease of use.

The other of the devices and the electrode assembly having a slot has a relief groove corresponding to the elastic arm. The elastic arm can undergo elastic deformation under external force, so that the snap fastener can be engaged into the slot or disengaged from the slot.

[0010] In one possible implementation of this application, the device body further has a first limiting structure, and the electrode assembly has a second limiting structure that matches the first limiting structure.

During the process of the conductive contact abutting against the elastic conductive element, the elastic conductive element can generate elastic deformation.

[0013] In one possible implementation of this application, the electrode assembly has at least two electrodes, each of which is electrically connected to a resilient conductive element or a conductive contact on the electrode assembly.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0029] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0030] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0031] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0032] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0033] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0034] As a type of physiotherapy device, surface electrical stimulation products typically use wires to connect the main body of the device to the electrode pads. The main wire connection methods include, but are not limited to, the insertion of pins at the end of the wires into the sockets on the main body of the device, the snapping of buttons, and the use of magnets to attract the wires to the main body of the device for electrical connection.

[0035] For wearable electrostimulation therapy devices, using interfaces such as magnetic snaps / buttons to connect the electrode wires to the device body has certain limitations. For example, the electrical transmission between the electrode and the device body usually relies on wires, which makes the therapy device messy and complex. This is especially true for therapy devices with multiple electrode pads, often resulting in multiple complex wires. Interfaces such as pin-to-pin, button-to-button, and magnetic attachment often only allow for single-polarity connections, meaning a single electrode pad can only connect to a single interface. The polarity of these interfaces is difficult to distinguish, meaning an electrode pad can be connected to either the positive or negative terminal, easily leading to incorrect wire connections.

[0036] This application provides a physiotherapy device that simplifies the connection process between the electrode assembly and the main body of the device, thereby improving the ease of use. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 This is a schematic diagram illustrating the application of the physiotherapy equipment provided in this application. Figure 2 This is a schematic diagram of the main body of the physiotherapy equipment provided in this application. Figure 3 Schematic diagram of the electrode assembly of the physiotherapy device provided in this application Figure 1 , Figure 4Schematic diagram of the electrode assembly of the physiotherapy device provided in this application Figure 2 , Figure 5 This is a cross-sectional structural diagram of the physiotherapy equipment provided in this application.

[0037] The physiotherapy device provided in this application includes: a device body 1 and an electrode assembly 2; wherein, the device body 1 has a corresponding first conductive element 13 and a first connecting structure 12, and the device body 1 can be worn on the limbs of a user 3; the electrode assembly 2 has a second conductive element 23 that matches the first conductive element 13, and the electrode assembly 2 also has a second connecting structure 22 that matches the first connecting structure 12, the second connecting structure 22 cooperates with the first connecting structure 12 to detachably connect the electrode assembly 2 to the device body 1; when the second connecting structure 22 is connected to the first connecting structure 12, the second conductive element 23 abuts against the first conductive element 13 to electrically connect the electrode assembly 2 to the device body 1.

[0038] In the embodiments of this application, such as Figure 1 As shown, the physiotherapy device can be worn on the limbs of the user 3. For example, the main body 1 of the device can be fixed to the user 3's legs, arms, or other parts. A shell 11 can be provided in the main body 1 to form a cavity. The electrostimulator, battery, etc. in the main body 1 can be placed in the cavity. The electrostimulator has a control circuit, which can apply pulse current to the electrodes 26 in the electrode assembly 2.

[0039] For example, straps that are easy to wear can be provided on the outer casing 11, such as elastic bands. The device body 1 can then be fixed to the legs, arms, or other parts of the body using the straps.

[0040] In this embodiment, electrical stimulation can be applied to the body surface of the user 3 via the electrode assembly 2. During physiotherapy, the electrode assembly 2 can be fixedly connected to the device body 1, and then the device body 1 can be fixed to the limb of the user 3, so that the electrode assembly 2 is in contact with the body surface of the user 3's limb.

[0041] For example, a first connecting structure 12 can be provided on the outer shell 11 of the device body 1, and correspondingly, a second connecting structure 22 can be provided on the electrode assembly 2, with the second connecting structure 22 being adapted to the first connecting structure 12. Furthermore, the second connecting structure 22 and the first connecting structure 12 can be configured as detachable structures. For instance, the second connecting structure 22 and the first connecting structure 12 can respectively employ a magnet and an iron block, or both the second connecting structure 22 and the first connecting structure 12 can be magnets. This allows the electrode assembly 2 to be fixedly connected to the device body 1 by magnetic attraction, and also facilitates the disassembly and separation of the electrode assembly 2 from the device body 1.

[0042] In another example, a first conductive element 13 can be provided in the device body 1, and correspondingly, a second conductive element 23 can be provided on the electrode assembly 2, the second conductive element 23 being adapted to the first conductive element 13. The first conductive element 13 is positioned on the device body 1 at a location corresponding to the first connecting structure 12, such as by passing the first conductive element 13 through the outer casing 11 of the device body 1, so that the portion of the first conductive element 13 inside the outer casing 11 is electrically connected to the main board inside the outer casing 11, and at least a portion of the first conductive element 13 is exposed on the surface of the outer casing 11, and the first conductive element 13 is adjacent to the first connecting structure 12. Alternatively, the second conductive element 23 can be positioned on the electrode assembly 2 adjacent to the second connecting structure 22, with a portion of the second conductive element 23 electrically connected to the electrode 26 in the electrode assembly 2, and the other portion of the second conductive element 23 exposed on the surface of the electrode assembly 2. For example, both the first conductive element 13 and the second conductive element 23 can be cylinders made of metal. In this way, after the electrode assembly 2 is connected to the device body 1 through the second connecting structure 22 and the first connecting structure 12, the cylinders serving as the first conductive element 13 and the second conductive element 23 can abut against each other.

[0043] The physiotherapy device provided in this application embodiment has a first connecting structure 12 on the device body 1 and a second connecting structure 22 on the electrode assembly 2. Both the first and second connecting structures 12 and 22 are detachable, facilitating the assembly and connection of the electrode assembly 2 to the device body 1 and allowing for easy disassembly and separation. Simultaneously, a first conductive element 13 corresponding to the first connecting structure 12 is provided on the device body 1, and a second conductive element 23 matching the first conductive element 13 is provided on the electrode assembly 2. Thus, during the assembly and connection of the electrode assembly 2 to the device body 1 via the second connecting structure 22 and the first connecting structure 12, the second conductive element 23 can abut against the first conductive element 13, thereby electrically connecting the electrode assembly 2 to the device body 1. Compared to related technologies where the electrode assembly 2 is electrically connected to the device body 1 via wires, the physiotherapy device provided in this application embodiment allows the electrode assembly 2 to be automatically electrically connected to the device body 1 during the assembly and connection process. Furthermore, there are no extending wires between the electrode assembly 2 and the device body 1. Therefore, the physiotherapy device provided in this application embodiment simplifies the connection process between the electrode assembly 2 and the device body 1, which is beneficial to improving the convenience of using the physiotherapy device.

[0044] In some possible embodiments of this application, such as Figure 2 and Figure 3As shown, the first connecting structure 12 and the first conductive element 13 are both disposed on the side of the device body 1 facing the limb, and the first conductive element 13 is located in the area where the first connecting structure 12 is located; the second connecting structure 22 and the second conductive element 23 are both disposed at one end of the electrode assembly 2, and the second conductive element 23 is located in the area where the second connecting structure 22 is located.

[0045] In this embodiment of the application, the first connecting structure 12 and the first conductive element 13 can both be disposed on the side of the device body 1 facing the user 3. For example, a recess matching the electrode assembly 2 can be provided on the outer shell 11 of the device body 1, and the depth of the recess is the same as or close to the thickness of the electrode assembly 2.

[0046] For example, the first conductive element 13 can be disposed on the housing 11 within the area where the first connecting structure 12 is located. For instance, if the first connecting structure 12 includes two magnets, the two magnets can be disposed on the housing 11 at intervals so that there is a gap between the two magnets. In this case, the first conductive element 13 can be disposed on the housing 11 within the area between the two magnets.

[0047] In another example, the electrode assembly 2 has an approximately sheet-like structure. The second connecting structure 22 can be disposed at one end of the sheet-like electrode assembly 2, and the second conductive element 23 can be disposed on the electrode assembly 2 at the same end as the second connecting structure 22. For example, if the second connecting structure 22 includes two iron plates, the two iron plates can be disposed at a distance from each other at the same end of the electrode assembly 2, and the second conductive element 23 can be disposed between the two iron plates.

[0048] In the above embodiments, since both the first connecting structure 12 and the first conductive element 13 are disposed on the side of the device body 1 facing the user 3's limb, after connecting the electrode assembly 2 to the device body 1 and fixing the device body 1 to the user 3's limb, the electrode assembly 2 can fit well against the user 3's body surface. Furthermore, the first conductive element 13 is located within the area where the first connecting structure 12 is located, and the second conductive element 23 is located within the area where the second connecting structure 22 is located. By restricting the relative positions of the second conductive element 23 and the first conductive element 13 through the first connecting structure 12 and the second connecting structure 22, the reliability of the connection between the second conductive element 23 and the first conductive element 13 can be improved.

[0049] In some possible embodiments of this application, such as Figure 4 and Figure 5 As shown, one of the first connecting structure 12 and the second connecting structure 22 includes a snap fastener, and the other of the first connecting structure 12 and the second connecting structure 22 includes a slot that matches the snap fastener.

[0050] In this embodiment, the electrode assembly 2 and the device body 1 can be detachably connected by a snap-fit ​​mechanism. For example, matching buckles and slots can be provided on the electrode assembly 2 and the device body 1, that is, the first connecting structure 12 and the second connecting structure 22 can be respectively set as matching buckles and slots.

[0051] For example, a groove serving as a slot can be provided on the outer casing 11 of the device body 1, the extension direction of which is perpendicular to the connection direction L between the electrode assembly 2 and the device body 1. Correspondingly, a buckle matching the slot can be provided on the electrode assembly 2, the buckle being a protruding bump, the extension direction of which is perpendicular to the connection direction L between the electrode assembly 2 and the device body 1. For example, the area between the two slots on the device body 1 can be set as a rectangular area with side lengths of 8 mm and 30 mm.

[0052] In another example, a hook-shaped protrusion serving as a latch can be provided on the outer casing 11 of the device body 1. Correspondingly, a slot matching the latch can be provided on the electrode assembly 2, the shape of which is adapted to the hook-shaped protrusion. In this way, a detachable connection between the electrode assembly 2 and the device body 1 can be achieved through the cooperation of the latch and the slot.

[0053] In the above embodiments, since the first connecting structure 12 and the second connecting structure 22 respectively include matching buckles and slots, the electrode assembly 2 and the device body 1 can be quickly connected or quickly disassembled by the buckles and slots, which simplifies the steps of connecting the electrode assembly 2 and the device body 1. Furthermore, by restricting the relative position of the electrode assembly 2 and the device body 1 through the buckles and slots, the accuracy of the electrode assembly 2's fit on the user's body surface can be improved.

[0054] In some possible embodiments of this application, such as Figure 5 As shown, one of the devices 1 and the electrode assembly 2 with a buckle has an elastic arm 25, and the buckle is disposed on the elastic arm 25. The other of the devices 1 and the electrode assembly 2 with a slot has a relief groove 15 corresponding to the elastic arm 25. The elastic arm 25 can undergo elastic deformation under external force so that the buckle can be engaged into the slot or disengaged from the slot.

[0055] In this embodiment, when the buckle is mounted on the electrode assembly 2, an elastic arm 25 can be provided on the electrode assembly 2. Correspondingly, a clearance groove 15 adapted to the elastic arm 25 can be provided on the outer shell 11 of the device body 1. The clearance groove 15 extends along the connection direction L on the outer shell 11 and can accommodate the elastic arm 25. Alternatively, when the buckle is mounted on the outer shell 11 of the device body 1, an elastic arm 25 can be provided on the outer shell 11. Correspondingly, a clearance groove 15 adapted to the elastic arm 25 can be provided on the electrode assembly 2. The clearance groove 15 extends along the connection direction L on the electrode assembly 2. The depth of the clearance groove 15 can be 3.2 mm. The elastic arm 25 can be provided on one of the two buckles, or it can be provided on both buckles.

[0056] For example, the elastic arm 25 can be configured as a cantilever structure, or it can be configured such that both ends of the elastic arm 25 are connected to the base 21 of the electrode assembly 2. When subjected to external force, the elastic arm 25 can undergo bending deformation along the perpendicular connection direction L. For instance, the elastic arm 25 can be configured as an approximate "V-shape" or "U-shape" structure. The included angle of the "V-shape" elastic arm 25 can be 24.6°, and the top opening width of the "V-shape" elastic arm 25 can be 2.4 mm. A buckle can be mounted on the elastic arm 25, and a slot can be mounted on the wall of the clearance groove 15. Thus, pushing the elastic arm 25 into the clearance groove 15 along the connection direction L allows the buckle to automatically engage in the slot, while applying force to the elastic arm 25 can cause the buckle to disengage from the slot.

[0057] In the above embodiments, since the buckle is set on the device body 1 or the electrode assembly 2 via the elastic arm 25, during the process of connecting the electrode assembly 2 and the device body 1, the buckle can move relative to the slot via the elastic arm 25, which helps to reduce the resistance of inserting the buckle into the slot. During the process of disassembling the electrode assembly 2 and the device body 1, the buckle can be pulled out of the slot by applying force to the elastic arm 25, thereby releasing the restriction on the movement of the electrode assembly 2 relative to the device body 1, and also reducing the force on the buckle (reducing the wear of the buckle and the slot), thereby improving the convenience of connecting or disassembling the electrode assembly 2 and the device body 1, and extending the service life of the buckle and the slot.

[0058] In some possible embodiments of this application, such as Figure 2 and Figure 3 As shown, the main body 1 of the device also has a first limiting structure 14, and the electrode assembly 2 has a second limiting structure 24 that matches the first limiting structure 14. The second limiting structure 24 cooperates with the first limiting structure 14 to limit the relative position of the electrode assembly 2 and the main body 1 of the device.

[0059] In this embodiment of the application, a matching first limiting structure 14 and a second limiting structure 24 can be respectively provided on the device body 1 and the electrode assembly 2, so as to uniquely determine the connection direction L between the electrode assembly 2 and the device body 1 through the first limiting structure 14 and the second limiting structure 24.

[0060] For example, the connection direction L between the electrode assembly 2 and the device body 1 can be restricted by the external shape of the structural component. For instance, the area on the device body 1 where the electrode assembly 2 connects can be set as a polygonal recess, and one end of the electrode assembly 2 connected to the device body 1 can be set as a polygonal structure matching the polygonal recess. That is, the polygonal recess on the outer shell 11 of the device body 1 serves as the first limiting structure 14, and the polygonal structure on the electrode assembly 2 serves as the second limiting structure 24. Thus, during the connection of the electrode assembly 2 and the device body 1, the polygonal structure and the polygonal recess can only connect with a uniquely determined relative position.

[0061] In the above embodiments, since a matching first limiting structure 14 and a second limiting structure 24 are respectively provided on the device body 1 and the electrode assembly 2, during the process of connecting the electrode assembly 2 and the device body 1, the electrode assembly 2 and the device body 1 can be connected with a uniquely determined relative position relationship by the cooperation of the first limiting structure 14 and the second limiting structure 24. This can reduce the occurrence of the electrode assembly 2 being connected to the device body 1 in an incorrect relative position, thus reducing the possibility of the polarity of the electrode assembly 2 being reversed.

[0062] In some possible embodiments of this application, such as Figure 2 and Figure 3 As shown, one of the first limiting structure 14 and the second limiting structure 24 includes a limiting protrusion, and the other of the first limiting structure 14 and the second limiting structure 24 includes a limiting groove.

[0063] In this embodiment, the first limiting structure 14 and the second limiting structure 24 can be configured as matching limiting protrusions and limiting grooves, respectively. For example, a limiting protrusion can be provided on the outer shell 11 of the device body 1, and a limiting groove can be provided on the electrode assembly 2. Alternatively, a limiting groove can be provided on the outer shell 11 of the device body 1, and a limiting protrusion can be provided on the electrode assembly 2. In this way, the electrode assembly 2 can be detachably connected to the device body 1 in the correct connection manner when the limiting protrusion and the limiting groove are aligned.

[0064] In the above embodiments, since the first limiting structure 14 and the second limiting structure 24 are respectively set as matching limiting protrusions and limiting grooves, it is beneficial to simplify the structure of the limiting structure, thereby reducing the difficulty of manufacturing the device body 1 and the electrode assembly 2.

[0065] In some possible embodiments of this application, such as Figure 4 and Figure 5 As shown, one of the first conductive element 13 and the second conductive element 23 includes an elastic conductive element, and the other of the first conductive element 13 and the second conductive element 23 includes a conductive contact corresponding to the elastic conductive element. During the process of the conductive contact abutting against the elastic conductive element, the elastic conductive element can generate elastic deformation.

[0066] In this embodiment, the first conductive element 13 and the second conductive element 23 can respectively employ compatible elastic conductive elements and conductive contacts. For example, an elastic conductive element can be provided on the device body 1, and a conductive contact can be provided on the electrode assembly 2. Alternatively, a conductive contact can be provided on the device body 1, and an elastic conductive element can be provided on the electrode assembly 2.

[0067] For example, the elastic conductive element can be a spring pin, and the conductive contact can be a thin metal sheet. When the spring pin is subjected to an axial force, it is compressed and undergoes elastic deformation. When the force is removed, the spring pin returns to its original shape.

[0068] In the above embodiments, since the first conductive element 13 and the second conductive element 23 respectively adopt compatible elastic conductive elements and conductive contacts, the elastic conductive element is deformed by the conductive contact, which can make the conductive contact and the elastic conductive element tightly abut together, which is beneficial to improving the reliability of the electrical connection between the electrode assembly 2 and the device body 1.

[0069] In some possible embodiments of this application, reference is made to Figure 6 , Figure 7 , Figure 8 and Figure 9 , Figure 6 Schematic diagram of the electrode assembly of the physiotherapy device provided in this application Figure 3 , Figure 7 Schematic diagram of the electrode assembly of the physiotherapy device provided in this application Figure 4 , Figure 8 Schematic diagram of the electrode assembly of the physiotherapy device provided in this application Figure 5 , Figure 9 Schematic diagram of the electrode assembly of the physiotherapy device provided in this application Figure 6 The electrode assembly 2 has at least two electrodes 26, each of which is electrically connected to an elastic conductive element or a conductive contact on the electrode assembly 2.

[0070] In the embodiments of this application, such as Figure 6 and Figure 8As shown, at least two electrodes 26 can be provided in the electrode assembly 2, that is, multiple electrodes 26 can be provided on the substrate 21 of the electrode assembly 2. The substrate 21 can be made of materials such as silicone, woven fabric, or plastic, and can be made into a sheet shape. The second connecting structure 22 can be made of rigid plastic, and the substrate 21 and the second connecting structure 22 can be fixedly connected by means of bonding, welding, snap-fitting, etc. Conductive contacts can be fixed on the substrate 21, and printed electrodes 26 of a certain area can be formed by extending from the conductive contacts through a silver paste filling process. Alternatively, an elastic conductive element can be fixed on the substrate 21, and printed leads 28 can be formed between the elastic conductive element and the electrode 26 to electrically connect the elastic conductive element to the corresponding electrode 26. The conductive contacts (elastic conductive elements) and electrodes 26 can be located on two opposite surfaces of the substrate 21, or on the same side surface of the substrate 21. The printed electrode 26 can be a silver electrode 26 or a graphite electrode 26.

[0071] For example, such as Figure 6 As shown, three rectangular electrodes 26 can be disposed on the substrate 21. The three rectangular electrodes 26 are arranged sequentially on the substrate 21 so that the electrodes 26 on the electrode assembly 2 are generally rectangular. Each rectangular electrode 26 is electrically connected to a conductive contact or an elastic conductive element. Figure 8 As shown, three polygonal electrodes 26 can be disposed on the substrate 21. The three polygonal electrodes 26 are fixed on the substrate 21 in a triangular arrangement so that the electrodes 26 on the electrode assembly 2 are triangular in shape. Each polygonal electrode 26 is electrically connected to a conductive contact or an elastic conductive element. The electrodes 26 are independent of each other, that is, any two electrodes 26 on the same electrode assembly 2 are not electrically connected.

[0072] Another example, such as Figure 7 and Figure 9 As shown, a cover layer 27 can be provided in the electrode assembly 2, and the cover layer 27 can be attached to at least all the electrodes 26. For example, the cover layer 27 can be attached to three rectangular electrodes 26, or the cover layer 27 can be attached to three polygonal electrodes 26, covering all the electrodes 26 in the same electrode assembly 2. The cover layer 27 can be made of hydrogel or the like. In this way, the cover layer 27 can increase the adhesion between the electrode assembly 2 and the limb, reduce the surface resistance, and improve the comfort of attaching the electrode assembly 2 to the body surface.

[0073] In the above embodiments, since there are at least two independent electrodes 26 on the same electrode assembly 2, the switching of the position, polarity, etc. of at least two electrodes 26 can be achieved by controlling the on / off circuit and polarity through the output circuit in the electrostimulator in the main body of the device 1 without adjusting the hardware connection. Thus, complex or customized body surface electrostimulation programs can be achieved through the same electrode assembly 2.

[0074] In some possible embodiments of this application, such as Figure 1 and Figure 2 As shown, the main body 1 of the device has at least two sets of corresponding first conductive elements 13 and first connection structures 12; the physiotherapy device includes electrode assemblies 2 that match each set of corresponding first conductive elements 13 and first connection structures 12.

[0075] In this embodiment of the application, multiple sets of electrode components 2 can be set in the physiotherapy device. For example, two, three or four sets of electrode components 2 can be set on the main body 1 of the device.

[0076] For example, a set of corresponding first conductive elements 13 and first connecting structures 12 can be respectively provided at opposite ends of the device body 1. A set of electrode assemblies 2 can be provided on the device body 1 through the same set of corresponding first conductive elements 13 and first connecting structures 12, so that a set of electrode assemblies 2 can be provided at both ends of the device body 1.

[0077] In another example, multiple electrodes 26 in one set of electrode assemblies 2 can be arranged in a rectangular pattern, meaning the overall shape of the electrodes 26 in this set of electrode assemblies 2 is approximately rectangular. Alternatively, multiple electrodes 26 in another set of electrode assemblies 2 can be arranged in a triangular pattern, meaning the overall shape of the electrodes 26 in this set of electrode assemblies 2 is approximately triangular. This allows the rectangular electrode assembly 2 to better conform to the skin surface at the lower leg, and the triangular electrode assembly 2 to better conform to the skin surface at the ankle. This improves the comfort of using the physiotherapy device and the firmness of the electrode assembly 2's fit on the skin surface.

[0078] In the above embodiments, since the physiotherapy device includes at least two sets of electrode components 2, the physiotherapy device can simultaneously perform electrotherapy on at least two parts of the body surface, which is beneficial to improving the electrotherapy efficiency of the physiotherapy device.

In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way.
