Description

Technical Field

[0001] The present application relates to the technical field of medical detection equipment, and in particular to an electrode device and an EEG electrode cap. Background Art

[0002] Bioelectric signals contain a large amount of physiological and pathological information. The monitoring and processing of bioelectric signals can not only provide doctors with a basis for clinical diagnosis, but also provide effective auxiliary treatment methods for certain diseases. The electrode device is the main basis for collecting bioelectric signals. Among them, in order to obtain better electrical signals, the dry electrode device needs to insert the conductor into the target object's skin, causing pain to the target object. In order to avoid pain for the target object and reduce impedance to obtain better signals, wet electrode devices are usually used at present, with the help of physiological saline or conductive paste to assist in collecting electrical signals. Conductive paste easily adheres to the target object's skin and detection equipment, and needs to be cleaned after the test, which is troublesome and cumbersome. Before using the existing physiological saline electrode device, the entire electrode device together with the device connection parts need to be immersed in saline, and the excess saline must be wiped clean, which makes the use process extremely inconvenient. Utility Model Content

[0003] The technical problem to be solved by the embodiments of the present application is that the existing electrode device is complicated and inconvenient to use, and an electrode device and an EEG electrode cap are provided to achieve the rapid disassembly and convenient use of the electrode device.

[0004] In a first aspect, the present application provides an electrode device, comprising:

[0005] Electrodes, the electrodes are used to detect electrical signals from a target object, or to provide electrical stimulation to the target object;

[0006] An electrode support assembly, the electrode support assembly comprising a cover and a housing, the housing having a first accommodating cavity for accommodating the electrode, the cover being disposed on one side of the housing;

[0007] a first magnetic member, the first magnetic member being disposed on the cover; and

[0008] a second magnetic member, the second magnetic member being disposed on the package body;

[0009] In which, the electrode device has a fixed state for fixing to the cap body and a separated state for separating from the cap body. When the cover body and the package body are magnetically connected through the first magnetic part and the second magnetic part, the electrode device is in the fixed state; when the first magnetic part and the second magnetic part of the electrode device are separated, and the package body and the cover body are detachable, the electrode device is in the separated state.

[0010] The electrode device provided in the embodiment of the present application includes electrodes for obtaining electrical signals from a target object or for giving electrical stimulation to the target object. The electrode device includes a first magnetic member and a second magnetic member. The first magnetic member is provided on the cover body, and the second magnetic member is provided on the package body, so that the first magnetic member and the second magnetic member are used to realize the quick disassembly and quick installation of the cover body and the package body in the electrode holder assembly. In addition, compared with the method of disassembly using threads or snaps, the method of disassembly of the cover body and the package body in the electrode device provided in the embodiment of the present application using the first magnetic member and the second magnetic member can achieve quick and convenient disassembly, and the cover body and the package body can be disassembled without interrupting use during use. When the electrode device is applied to a brain electrode cap, the method of disassembly using threads or snaps will cause damage to the cap body of the brain electrode cap. This is because the cap body of the brain electrode cap is usually a silicone cap body with a mounting hole, and the cap body has an inner surface and an outer surface. When installed, the cover body is located on the outer surface, and the package body is located on the inner surface; when the electrode device and the cap body are installed or removed using threads, the cover body and the package body need to be rotated in opposite directions, and the cover body and the package body will cause friction to the cap body during the installation and removal process; when the electrode device and the cap body are installed using snaps, the cover body and the package body need to be squeezed toward the cap body respectively, and the cover body and the package body will cause friction to the cap body during the installation process. The cover body and the package body in the electrode bracket assembly provided in the embodiment of the present application are disassembled using the first magnetic part and the second magnetic part, which avoids damage to the cap body when the electrode device is used in the brain electrode cap.

[0011] In some embodiments, the cover comprises:

[0012] a main body portion, the main body portion having a first surface facing the package body, the first surface having a first groove, and the first groove is used to accommodate the first magnetic member; and

[0019] The fixing portion abuts against a portion of the second sub-surface facing away from the base sub-surface and abuts against the third sub-surface.

[0020] In the electrode device provided in the embodiments of the present application, the main body includes a base sub-section, a first sub-sidewall, and a second sub-sidewall. The fixing portion abuts against a portion of the second sub-surface facing away from the base sub-section, as well as against the third sub-surface. This allows the cover to be lowered in a direction perpendicular to the surface facing the enclosure, and the fixing portion's projection area on the surface facing the enclosure is smaller, thereby making the cover thin and easy to use.

[0021] In some embodiments, the package body has a second surface facing the cover body, the second surface has a second groove, and the second groove is used to accommodate the second magnetic member.

[0035] When the electrode device is in a fixed state, there is a gap between the cover and the enclosure, and the gap is used for the conductive wire to pass through.

[0036] In the electrode device provided in the embodiment of the present application, the electrode device also includes a conductive wire, and there is a gap between the cover body and the package body for the conductive wire to pass through. The gap is used to avoid fatigue loss caused by multiple bending at the connection between the wire and the first detection part, thereby enhancing the service life of the wire and the stability of electrical signal transmission. It is further realized that the electrode device does not require additional wire holes, the structure is simpler, and the arrangement of the wire is more convenient when the cover body and the package body are installed and removed.

The electrode assembly further includes a covering member that encases the flexible absorbent member to prevent the conductive medium in the flexible absorbent member from being squeezed and rapidly leaking out during use, potentially affecting the target subject's comfort and the stability of electrical signal transmission.

[0041] In the electrode device provided in the embodiment of the present application, the electrode device also includes a conductive wire, and there is a gap between the cover body and the package body for the conductive wire to pass through.

[0043] In the electrode device provided in the embodiments of the present application, the cover body has a second accommodating cavity to connect the first accommodating cavity with the outside world. This allows the electrode device to be refilled through the second accommodating cavity when the conductive medium is exhausted or nearly exhausted during use, eliminating the need to pause use. This further enables efficient use of the electrode device and increases the duration of a single use of the electrode device.

DETAILED DESCRIPTION

[0065] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0066] The terms "first," "second," and the like in the specification, claims, and drawings of this application are used to distinguish between different objects rather than to describe a specific order. In addition, the terms "include," "include," and "have," and any variations thereof, are intended to cover non-exclusive inclusions.

[0067] References herein to "embodiments" or "implementations" mean that a particular feature, structure, or characteristic described in connection with the embodiment or implementation may be included in at least one implementation of the present application. The appearance of such phrases in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0068] See also Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the three-dimensional structure of the electrode device in a fixed state according to one embodiment of the present invention; Figure 2This is a schematic cross-sectional structural diagram of an electrode device in a fixed state along line AA according to one embodiment of the present invention; Figure 3 It is a schematic diagram of the cross-sectional structure of the electrode device in a separated state along the AA line according to one embodiment of the present invention. One embodiment of the present application provides an electrode device 10 including an electrode 11, an electrode holder assembly 12, a first magnetic member 13 and a second magnetic member 14. The electrode 11 is used to detect the electrical signal of the target object, or to give electrical stimulation to the target object. Among them, the electrode holder assembly 12 includes a cover body 121 and a package body 122. The package body 122 has a first accommodating cavity 1223. The first accommodating cavity 1223 is used to accommodate the electrode 11. The cover body 121 is arranged on one side of the package body 122. The first magnetic member 13 is arranged on the cover body 121, and the second magnetic member 14 is arranged on the package body 122. In which, the electrode device 10 has a fixed state for fixing to the cap body and a separated state for separating from the cap body. When the cover body 121 and the package body 122 are magnetically connected through the first magnetic part 13 and the second magnetic part 14, the electrode device 10 is in the fixed state; when the first magnetic part 13 and the second magnetic part 14 are separated, and the package body 122 and the cover body 121 are detachable, the electrode device 10 is in the separated state.

[0069] When the electrodes 11 are used to detect the target subject's electrical signals, they can detect the target subject's EEG signals. Therefore, the electrode device 10 can be a EEG electrode detection device. When the electrodes 11 are used to detect the target subject's electrical signals, the electrode device 10 is electrically connected to a signal receiving device to transmit the target subject's electrical signals to the signal receiving device, so that the signal receiving device can determine the target subject's activity status or determine whether the target subject is healthy based on the target subject's electrical signals.

[0070] When the electrodes 11 are used to provide electrical stimulation to a target subject, they can be applied to the target subject's head to provide electrical stimulation to the target subject's brain. Therefore, the electrode assembly 10 can be a brain electrical stimulation therapy device. When the electrodes 11 are used to provide electrical stimulation to a target subject, the electrode assembly 10 is configured to electrically connect to a bioelectrical stimulation therapy device to transmit the electrical current of the bioelectrical stimulation therapy device to the target subject's skin receiving the electrical stimulation therapy, thereby providing bioelectrical stimulation therapy to the target subject.

[0071] The electrode holder assembly 12 is used to accommodate the electrode 11. The shape of the electrode holder assembly 12 can be, but is not limited to, a cylinder or a prism, and is not limited here. The cover 121 included in the electrode holder assembly 12 can be made of hard rubber material, covering one side of the package 122. The package 122 can be, but is not limited to, made of silicone material, and the package 122 can be integrally formed. When the package 122 made of silicone material and the cover 121 made of hard rubber material are combined to form a fixed state, the package 122 and the cover 121 can be tightly fixed due to the softness and elastic deformation of silicone material. The package 122 has a first accommodating cavity 1223, and the electrode 11 is accommodated in the first accommodating cavity 1223. Therefore, the cover 121 and the package 122 can protect the electrode 11 and prevent damage to the electrode 11.

[0072] The first magnetic member 13 may be, but is not limited to, one or more magnets. Optionally, the first magnetic member 13 is a ring magnet. The second magnetic member 14 may be, but is not limited to, one or more magnets. Optionally, the second magnetic member 14 is a ring magnet. Optionally, the inner diameter and outer diameter of the ring magnet serving as the first magnetic member 13 are the same as or approximately the same as the inner diameter and outer diameter of the ring magnet serving as the second magnetic member 14.

[0073] When the cover 121 and the enclosure 122 are connected, so that the electrode device 10 is in the fixed state, the cover 121 and the enclosure 122 are quickly connected under the magnetic force of the first magnetic member 13 and the second magnetic member 14. Furthermore, the correspondingly arranged first magnetic member 13 and the second magnetic member 14 can achieve accurate alignment of the enclosure 122 and the cover 121 when they are connected. When the cover 121 and the enclosure 122 are disassembled, so that the electrode device 10 is in the separated state, the cover 121 and the enclosure 122 can quickly and conveniently complete the separation action, avoiding the complicated disassembly process of snap-on or threaded connection.

[0074] In the related art, when the electrode device 10 is applied to a brain electrode cap, the method of disassembly using threads or snaps will cause damage to the cap body of the brain electrode cap. This is because the cap body of the brain electrode cap is usually a silicone cap body with a mounting hole, and the cap body has an inner surface and an outer surface. During installation, the cover body 121 is located on the outer surface, and the package body 122 is located on the inner surface; when the electrode device 10 and the cap body are installed or disassembled using threads, the cover body 121 and the package body 122 need to be rotated in opposite directions. During the installation and disassembly process, the cover body 121 and the package body 122 will cause friction to the cap body. When the electrode device 10 and the cap body are installed using snaps, the cover body 121 and the package body 122 need to be squeezed toward the cap body respectively. During the installation process, the cover body 121 and the package body 122 will cause wear to the cap body. The cover 121 and the enclosure 122 in the electrode holder assembly 12 provided in the embodiment of the present application are disassembled using the first magnetic member 13 and the second magnetic member 14 , thereby avoiding damage to the cap when the electrode device 10 is applied to a brain electrode cap.

[0075] In summary, the electrode device 10 provided in the embodiment of the present application includes an electrode 11 for obtaining an electrical signal from a target object or for giving electrical stimulation to a target object. The electrode device 10 includes a first magnetic member 13 and a second magnetic member 14. The first magnetic member 13 is provided on the cover 121, and the second magnetic member 14 is provided on the enclosure 122. Thus, the first magnetic member 13 and the second magnetic member 14 are used to realize the quick disassembly and quick installation of the cover 121 and the enclosure 122 in the electrode holder assembly 12. In addition, when the electrode device 10 is applied to an EEG electrode cap, the first magnetic member 13 and the second magnetic member 14 can be used to assemble the electrode device 10 with the cap body of the EEG electrode cap, which is convenient and quick and will not cause damage to the cap body.

[0076] Please refer again Figure 2 and Figure 3 Also see Figure 4 and Figure 5 , Figure 4 yes Figure 3 A partial enlarged view of the electrode device II shown in FIG; Figure 5It is a schematic diagram of the cross-sectional structure of the cover body along the AA line of one embodiment of the present invention. Furthermore, in one embodiment, the cover body 121 includes a main body portion 1211 and a fixing portion 1212. The main body portion 1211 has a first surface 1211f facing the enclosure 122, and the first surface 1211f has a first groove 1211d, and the first groove 1211d is used to accommodate the first magnetic member 13. The fixing portion 1212 is arranged corresponding to the first groove 1211d and is fixed to the main body portion 1211, and the fixing portion 1212 cooperates with the main body portion 1211 to fix the first magnetic member 13.

[0077] The cover body 121 includes a main body 1211, and the main body 1211 has a first groove 1211d to accommodate the first magnetic part 13. The shape of the projection of the first groove 1211d on the first surface 1211f can be the same as or similar to the shape of the projection of the first magnetic part 13 on the first surface 1211f, and the area of the projection of the first groove 1211d on the first surface 1211f is slightly larger than the area of the projection of the first magnetic part 13 on the first surface 1211f; the area of the projection of the first groove 1211d on the first surface 1211f can also be significantly larger than the area of the projection of the first magnetic part 13 on the first surface 1211f; optionally, the first groove 1211d is an annular groove. The first magnetic part 13 can be, but is not limited to, glued, clamped or extruded to the first groove 1211d. The first magnetic part 13 can also be placed in the first groove 1211d without being connected to the first groove 1211d.

[0078] The main body 1211 has a first surface 1211f facing the package body 122, and the first surface 1211f has a first groove 1211d, and the first groove 1211d is used to accommodate the first magnetic member 13. This makes the first magnetic member 13 closer to the package body 122. When the same magnetic member, including but not limited to the same shape, mass, and magnetic strength, is used as the first magnetic member 13, being closer to the package body 122 will make the magnetic attraction between the first magnetic member 13 and the second magnetic member 14 stronger, thereby making the connection between the cover 121 and the package body 122 more stable and not easy to fall off.

[0079] The cover 121 includes a fixing portion 1212, which is provided corresponding to the first groove 1211d, fixed to the main body 1211, and cooperates with the main body 1211 to fix the first magnetic member 13. Optionally, the depth of the first groove 1211d in the direction perpendicular to the surface of the package body 122 is greater than the height of the first magnetic member 13 in the direction perpendicular to the surface of the package body 122, the shape of the fixing portion 1212 projected on the surface facing the package body 122 is the same as or similar to the shape of the first groove 1211d projected on the surface facing the package body 122, and the area of the first groove 1211d projected on the surface facing the package body 122 is slightly larger than the area of the fixing portion 1212 projected on the surface facing the package body 122; the fixing portion 1212 can be, but is not limited to, glued, snapped, or extruded to the first groove 1211d to fix the first magnetic member 13. Among them, optionally, the depth of the first groove 1211d in the direction perpendicular to the surface of the package body 122 is greater than the height of the first magnetic part 13 in the direction perpendicular to the surface of the package body 122, and the area of the fixing portion 1212 projected on the surface facing the package body 122 is greater than the area of the first groove 1211d projected on the surface facing the package body 122; the fixing portion 1212 can be but is not limited to being connected to the surface facing the package body 122 by snapping or gluing. Among them, optionally, the depth of the first groove 1211d in the direction perpendicular to the surface of the package 122 is smaller than the height of the first magnetic part 13 in the direction perpendicular to the surface of the package 122, and part of the first magnetic part 13 protrudes from the groove; the fixing part 1212 has a groove on the surface facing the main body 1211 corresponding to the part of the first magnetic part 13 protruding from the groove, and the fixing part 1212 and the main body 1211 can be but are not limited to being connected by snapping or gluing, and the part of the first magnetic part 13 protruding from the groove is accommodated in the groove of the fixing part 1212 on the surface facing the main body 1211.

[0080] In summary, in the electrode device 10 provided in the embodiment of the present application, the cover 121 includes a main body 1211, and the main body 1211 has a first groove 1211d to accommodate the first magnetic member 13. The cover 121 includes a fixing portion 1212, and the fixing portion 1212 cooperates with the main body 1211 to achieve stable fixation of the first magnetic member 13 and prevent it from falling off.

[0081] Please refer again Figure 2 、 Figure 3 、 Figure 4 and Figure 5 Also see Figure 6 , Figure 6 It is a schematic diagram of the cross-sectional structure of the main body along line AA of an embodiment of the present utility model. Furthermore, in one embodiment, the main body 1211 includes a base sub-portion 1211a, a first sub-side wall 1211b and a second sub-side wall 1211c. The first sub-side wall 1211b is arranged on the side of the base sub-portion 1211a close to the enclosure 122, and the first sub-side wall 1211b has a first sub-surface 1211h facing away from the base sub-portion 1211a and a second sub-surface 1211i bent and connected to the first sub-surface 1211h. The second sub-side wall 1211c is arranged on the side of the base sub-portion 1211a close to the enclosure 122, and the second sub-side wall 1211c is spaced apart from the first sub-side wall 1211b, and the second sub-side wall 1211c is arranged on the side facing the second sub-surface 1211i. The second sub-sidewall 1211c has a third sub-surface 1211j facing away from the base sub-portion 1211a. The third sub-surface 1211j is closer to the base sub-portion 1211a than the first sub-surface 1211h. The base sub-portion 1211a, the first sub-sidewall 1211b, and the second sub-sidewall 1211c collectively define the first groove 1211d. The fixing portion 1212 abuts against a portion of the second sub-surface 1211i facing away from the base sub-portion 1211a and against the third sub-surface 1211j.

[0082] The main body 1211 includes a base sub-portion 1211a, a first sub-sidewall 1211b, and a second sub-sidewall 1211c. The base sub-portion 1211a connects the various components of the main body 1211; the base sub-portion 1211a, the first sub-sidewall 1211b, and the second sub-sidewall 1211c jointly define the first groove 1211d to accommodate the first magnetic member 13; the first sub-sidewall 1211b and the second sub-sidewall 1211c jointly abut against the fixing portion 1212, and together with the fixing portion 1212, fix the first magnetic member 13. Optionally, the fixing portion 1212 is an annular columnar structure, the annular columnar inner surface of the annular columnar fixing portion 1212 abuts against the portion of the second sub-surface 1211i facing away from the base sub-portion 1211a, and the annular surface of one side of the annular columnar fixing portion 1212 abuts against the third sub-surface 1211j. The abutting manner may be but is not limited to gluing or clamping.

[0083] The side surface of the fixing portion 1212 facing the main body 1211 and the first groove 1211d jointly accommodate and constrain the first magnetic member 13. The first magnetic member 13 can be connected to the fixing portion 1212 by methods including, but not limited to, gluing or snapping. The first magnetic member 13 may also not be connected to the fixing portion 1212. Optionally, the surface of the fixing portion 1212 facing the enclosure 122 is flush or approximately flush with the first sub-surface 1211h, so that the lower surface of the cover 121 is approximately flat, thereby ensuring that the cover 121 can be tightly connected to the enclosure 122 when magnetically connected.

[0084] Compared with the main body 1211, which does not include the base sub-part 1211a, the first sub-side wall 1211b and the second sub-side wall 1211c, the fixing part 1212 is directly glued or clamped to the surface of the main body 1211 facing the package body 122. The fixing part 1212 abuts against the partial surface of the second sub-surface 1211i away from the base sub-part 1211a and abuts against the third sub-surface 1211j, so that the height of the cover body 121 in the direction perpendicular to the surface facing the package body 122 can be lower, and the projection area of the fixing part 1212 on the surface facing the package body 122 is smaller, so that the cover body 121 is light and thin and easier to use. Furthermore, the fixing portion 1212 abuts against a portion of the second sub-surface 1211i away from the base sub-surface 1211a and the third sub-surface 1211j, increasing the number of surfaces abutting against the fixing portion 1212 and the main body portion 1211, making the connection between the fixing portion 1212 and the main body portion 1211 more stable.

[0085] In summary, in the electrode device 10 provided in the embodiments of the present application, the body portion 1211 includes a base sub-portion 1211a, a first sub-sidewall 1211b, and a second sub-sidewall 1211c. The fixing portion 1212 abuts against a portion of the second sub-surface 1211i facing away from the base sub-portion 1211a, and also abuts against the third sub-surface 1211j. This allows the cover 121 to be lowered in a direction perpendicular to the first surface 1211f, and the projection area of the fixing portion 1212 on the first surface 1211f is smaller, thereby making the cover 121 thin and easy to use.

[0086] Please refer again Figure 2 、 Figure 3 、 Figure 4 and Figure 5 Also see Figure 6 , Figure 61 is a schematic cross-sectional view of the main body of an embodiment of the present invention along line AA. Further, in one embodiment, the enclosure 122 has a second surface 1221b facing the cover 121, and the second surface 1221b has a second groove 1221a for accommodating the second magnetic member 14.

[0087] The package body 122 has a second surface 1221b facing the cover body 121, and the second surface 1221b has a second groove 1221a. The second groove 1221a is used to accommodate the second magnetic member 14. This makes the second magnetic member 14 closer to the cover body 121. When the same magnetic member, including but not limited to the same shape, mass, and magnetic strength, is used as the second magnetic member 14, the closer distance to the cover body 121 will make the magnetic attraction between the second magnetic member 14 and the first magnetic member 13 stronger, thereby making the connection between the package body 122 and the cover body 121 more stable and less likely to fall off.

[0088] Among them, the connection method between the package body 122 and the second magnetic part 14 can be but is not limited to injection molding or gluing. The purpose of stably connecting the second magnetic part 14 and the package body 122 can be achieved without the need for other parts to fix. Among them, the groove depth of the second groove 1221a can be greater than the groove depth of the first groove 1211d; accordingly, the height of the second magnetic part 14 in the direction perpendicular to the second surface 1221b can be greater than the height of the first magnetic part 13 in the direction perpendicular to the second surface 1221b. The deeper groove depth of the first groove 1211d and the higher height of the second magnetic part 14 in the direction perpendicular to the second surface 1221b can make the contact area between the second magnetic part 14 and the package body 122 larger, thereby making the connection between the package body 122 and the second magnetic part 14 more stable, and the second magnetic part 14 is not easy to fall off.

[0089] To sum up, in the electrode device 10 provided in the embodiment of the present application, the enclosure 122 has a second groove 1221a to accommodate the second magnetic member 14; the second groove 1221a is arranged on the second surface 1221b facing the cover 121 to achieve a stable connection between the enclosure 122 and the cover 121.

The portions of the first sub-cavity 1223a and the second sub-cavity 1223b adjacent to the first sub-cavity 1223a are used to accommodate the electrode 11. The first accommodating chamber 1223 includes the first sub-cavity 1223a and the second sub-cavity 1223b.

[0091] The enclosure 122 includes a first connecting portion 1221 and a second connecting portion 1222.

Among them, optionally, the first connecting part 1221 is an annular cylinder, the second connecting part 1222 is an annular cylinder, the outer diameter of the first inner wall surface 1221c of the first connecting part 1221 is consistent with or approximately consistent with the outer diameter of the second inner wall surface 1222b of the second connecting part 1222, and the inner diameter of the first inner wall surface 1221c of the first connecting part 1221 is smaller than the inner diameter of the second inner wall surface 1222b of the second connecting part 1222; so that the thickness of the inner wall of the first connecting part 1221 is greater than the thickness of the inner wall of the second connecting part 1222, thereby achieving that the package body 122 has more space to set the second accommodating part and the second magnetic part 14, and further achieving a more stable connection between the second magnetic part 14 and the package body 122. In addition, the thickness of the inner wall of the first connecting part 1221 can be greater than the thickness of the inner wall of the second connecting part 1222, and the cavity volume of the second sub-cavity 1223b can be larger than the first sub-cavity 1223a, thereby further allowing the second sub-cavity 1223b to have a larger space to accommodate the electrode 11.

[0093] In summary, in the electrode device 10 provided in the embodiment of the present application, the enclosure 122 has a first connecting portion 1221 to accommodate the second magnetic member 14. The first connecting portion 1221 has a first sub-cavity 1223a, the enclosure 122 has a second connecting portion 1222, and the second connecting portion 1222 has a second sub-cavity 1223b. The first sub-cavity 1223a and the second sub-cavity 1223b adjacent to the first sub-cavity 1223a accommodate the electrode 11.

[0094] Please refer again Figure 4 、 Figure 5 、 Figure 6 and Figure 8 Also see Figure 9 、 Figure 10 and Figure 11 , Figure 9 This is a schematic cross-sectional structural diagram of an electrode device in a fixed state along line AA according to one embodiment of the present invention; Figure 10 This is a schematic diagram of the three-dimensional structure of an electrode according to one embodiment of the present invention; Figure 11It is a schematic diagram of the cross-sectional structure of an electrode along line BB in one embodiment of the present utility model. Furthermore, in one embodiment, the electrode 11 includes a first detection portion 111 and a second detection portion 112. A portion of the first detection portion 111 protrudes from the side of the first connection portion 1221 away from the second connection portion 1222, and the first detection portion 111 fits the first inner wall surface 1221c. The second detection portion 112 is bent and connected to the first detection portion 111, and the second detection portion 112 fits the connection surface 1222a. The cover body 121 also has a limiting groove 1211e, and when the electrode device 10 is in a fixed state, the limiting groove 1211e accommodates the portion of the electrode 11 protruding from the first connection portion 1221.

[0095] The electrode 11 includes a first detection portion 111, which conforms to the first wall surface, saving space in the first accommodating cavity 1223 while providing a transmission channel for electrical signals. A portion of the first detection portion 111 protrudes from the side of the first connecting portion 1221 facing away from the second connecting portion 1222, allowing the first detection portion 111 to extend beyond the housing 122. The portion of the first detection portion 111 protruding from the first connecting portion 1221 can be electrically connected to an electrical signal receiving device or a bioelectrical stimulation therapy device.

[0096] When the electrode device 10 is used to detect an electrical signal from a target subject, the portion of the first detecting portion 111 protruding from the first connecting portion 1221 is electrically connected to a signal receiving device to transmit the target subject's electrical signal to the signal receiving device, so that the signal receiving device can determine the target subject's activity status or determine whether the target subject is healthy based on the target subject's electrical signal. When the electrode device 10 is used to provide electrical stimulation to a target subject, the portion of the first detecting portion 111 protruding from the first connecting portion 1221 is electrically connected to a bioelectric stimulation treatment device to transmit the current of the bioelectric stimulation treatment device to the target subject's skin receiving the electrical stimulation treatment, thereby providing bioelectric stimulation treatment to the target subject.

[0097] The electrode 11 includes a second detection portion 112, which is bent and connected to the first detection portion 111. The second detection portion 112 conforms to the connection surface 1222a, saving space in the first accommodating cavity 1223 while providing a transmission channel for the electrical signal. The first detection portion 111 conforms to the first wall surface, and the second detection portion 112 conforms to the connection surface 1222a, achieving a tight connection between the electrode 11 and the enclosure 122. The enclosure 122 can be made of silicone. Since silicone is easily elastically deformable, it can achieve elastic compression between the electrode 11 and the enclosure 122, thereby achieving a stable connection between the electrode 11 and the enclosure 122.

[0098] The cover 121 also has a limiting groove 1211e. When the electrode device 10 is in a fixed state, the limiting groove 1211e accommodates the portion of the electrode 11 protruding from the first connecting portion 1221. When the package 122 and the cover 121 are connected, the electrode device 10 is in a fixed state, and the portion of the first detection portion 111 protruding from the first connecting portion 1221 can be accommodated in the limiting groove 1211e. As a result, the electrode device 10 in the fixed state is not affected by the portion of the first detection portion 111 protruding from the first connecting portion 1221, further achieving a tight connection between the package 122 and the cover 121. Furthermore, the limiting groove 1211e corresponds to the portion of the first detection portion 111 protruding from the first connecting portion 1221, assisting in the alignment and connection of the package 122 and the cover 121.

[0099] In summary, in the electrode device 10 provided in the embodiments of the present application, the electrode 11 further includes a first detection portion 111 and a second detection portion 112. The first detection portion 111 is in contact with the first inner wall surface 1221c, and the second detection portion 112 is in contact with the connection surface 1222a, thereby stably fixing the conductive member relative to the enclosure 122 to ensure the stability of electrical signal conduction of the conductive component. In addition, the cover 121 further includes a retaining groove 1211e to accommodate the portion of the electrode 11 protruding from the first connection portion 1221 when the cover 121 and the enclosure 122 are connected and the electrode device 10 is in the fixed state.

[0100] Please refer again Figure 2 and Figure 11Furthermore, in one embodiment, the electrode assembly 10 further includes a conductive wire 15, the conductive wire 15 connecting the portion of the first detection portion 111 protruding from the first sub-cavity 1223a. When the electrode assembly 10 is in a fixed state, a gap 123 is defined between the cover 121 and the enclosure 122, the gap 123 being used to pass the conductive wire 15.

[0101] The electrode device 10 also includes a conductive wire 15 connecting the portion of the first detection portion 111 protruding from the first sub-cavity 1223a. The conductive wire 15 realizes the transmission of electrical signals to solve the technical problem that the electrode 11 is difficult to electrically connect to a signal receiving device or a bioelectric stimulation treatment device at a long distance. When the electrode device 10 is used to detect the electrical signal of the target object, the conductive wire 15 is electrically connected to the signal receiving device to transmit the electrical signal of the target object to the signal receiving device, so that the signal receiving device can determine the activity state of the target object or determine whether the target object is healthy based on the electrical signal of the target object. When the electrode device 10 is used to give electrical stimulation to the target object, the conductive wire 15 is electrically connected to the bioelectric stimulation treatment device to transmit the current of the bioelectric stimulation treatment device to the skin of the target object that receives electrical stimulation treatment, so as to implement bioelectric stimulation treatment on the target object.

[0102] When the electrode device 10 is in a fixed state, there is a gap 123 between the cover 121 and the enclosure 122, and the gap 123 is used to pass the conductive wire 15. The conductive wire 15 can be electrically connected to the portion of the first detection portion 111 corresponding to the gap 123, and its specific connection method can be but is not limited to welding. When the cover 121 and the enclosure 122 are connected so that the motor bracket assembly is in the fixed state, the wire can pass through the gap 123, achieving the technical effect that the wire does not need to be bent when the motor bracket assembly is in the fixed state, avoiding fatigue loss caused by multiple bending at the connection between the wire and the first detection portion 111, and enhancing the service life of the wire and the stability of electrical signal conduction.

[0103] Furthermore, when the cover body 121 and the enclosure body 122 are connected so that the motor bracket assembly is in the fixed state, the conductive wire 15 passes through the gap between the cover body 121 and the enclosure body 122, so that the electrode bracket assembly 12 does not need to have an additional wire hole to allow the wire to pass through the motor bracket assembly and be connected to the electrical signal receiving device or the bioelectric stimulation treatment device, which simplifies the structure of the electrode bracket assembly 12, saves the manufacturing cost of the electrode bracket assembly 12, and improves the use efficiency of the electrode device 10.

[0104] When the technical solution of this embodiment is applied to an EEG electrode cap, the electrode 11 is placed in the housing 122, the first detection portion 111 protrudes from the first sub-cavity 1223a, and the wire is connected to the portion of the first detection portion 111 protruding from the first sub-cavity 1223a. The housing 122 is located on the inner surface of the cap body, and the portion of the first detection portion 111 protruding from the first sub-cavity 1223a passes through the cap body through the inner surface toward the outer surface. The wire is located on one side of the outer surface, with one end connected to the portion of the first detection portion 111 protruding from the first sub-cavity 1223a, and the other end connected to the electrode detection device or the bioelectric stimulation treatment device. The cover 121 is magnetically connected to the enclosure 122 via the first magnetic member 13 and the second magnetic member 14, corresponding to the cap through-hole. The cap is positioned between a surface formed by the lower surface of the fixing portion 1212 of the cover 121 and the first sub-surface 1211h of the first sub-sidewall 1211b, and the second surface 1221b of the enclosure 122. The limiting groove 1211e accommodates the portion of the first detection portion 111 that protrudes from the first sub-cavity 1223a. The wire is positioned between the first sub-surface 1211h of the first sub-sidewall 1211b of the cover 121 and a gap on the outside of the cap.

[0105] To sum up, in the electrode device 10 provided in the embodiment of the present application, the electrode device 10 also includes a conductive wire 15, and there is a gap 123 between the cover body 121 and the package body 122 for passing the conductive wire 15. The gap 123 is used to avoid fatigue loss caused by multiple bending at the connection between the wire and the first detection part 111, thereby enhancing the service life of the wire and the stability of electrical signal conduction, and further realizing that the electrode device 10 does not need to open an additional wire hole, the structure is simpler, and the arrangement of the wire is more convenient when the cover body 121 and the package body 122 are installed and disassembled.

[0106] Please refer again Figure 2 、 Figure 3 、 Figure 11 , and see Figure 12 . Figure 12 This is an exploded view of an electrode device according to one embodiment of the present invention. Furthermore, in one embodiment, the electrode device 10 further includes a flexible absorbent member 16 and a covering member 17. The flexible absorbent member 16 is disposed within the second sub-cavity 1223b and abuts the second detection portion 112. The covering member 17 covers the flexible absorbent member 16 and abuts the second inner wall surface 1222b.

[0107] When the electrode device 10 is in use, the first accommodating cavity 1223 is also filled with a conductive medium, which can be, but is not limited to, physiological saline. When the electrode device 10 is used to detect the electrical signal of the target object, the conductive medium transmits the electrical signal of the target object to the signal receiving device, so that the signal receiving device can determine the activity state of the target object or determine whether the target object is healthy based on the electrical signal of the target object. When the electrode device 10 is used to provide electrical stimulation to the target object, the conductive medium transmits the current of the bioelectric stimulation treatment device to the skin of the target object that receives the electrical stimulation treatment, so as to implement bioelectric stimulation treatment on the target object.

[0108] The electrode device 10 also includes a flexible absorbent member 16, which is used to absorb and contain the conductive medium to achieve the accommodation of the fluid conductive medium. The flexible absorbent member 16 can slowly release the conductive medium to the skin surface of the target object. The flexible absorbent member 16 can be made of an elastic porous hydrophilic material, and its specific material can be, but is not limited to, hydrogel, absorbent fiber or absorbent sponge. The flexible absorbent member 16 has the characteristic of being able to obtain elastic deformation through extrusion, and can be stably connected to the second inner wall surface 1222b of the second sub-cavity 1223b through elastic extrusion.

[0109] Furthermore, in one embodiment of the present application, optionally, the first connecting part 1221 is an annular cylinder, the second connecting part 1222 is an annular cylinder, the outer diameter of the first inner wall surface 1221c of the first connecting part 1221 is consistent with or approximately consistent with the outer diameter of the second inner wall surface 1222b of the second connecting part 1222, and the inner diameter of the first inner wall surface 1221c of the first connecting part 1221 is smaller than the inner diameter of the second inner wall surface 1222b of the second connecting part 1222; so that the thickness of the inner wall of the first connecting part 1221 is greater than the thickness of the inner wall of the second connecting part 1222, thereby achieving the second accommodating cavity 1211g having a larger volume to accommodate the flexible water-absorbing part 16, thereby achieving the technical effect that the electrode device 10 can accommodate more conductive media and obtain a longer single use time. In addition, the thickness of the inner wall of the first connecting portion 1221 can be greater than the thickness of the inner wall of the second connecting portion 1222, and the cavity volume of the second sub-cavity 1223b can be larger than the first sub-cavity 1223a, thereby further allowing the second sub-cavity 1223b to have a larger space to accommodate the flexible water-absorbing member 16.

[0110] Furthermore, in one embodiment of the present application, the electrode 11 includes a second detection portion 112, which is bent and connected to the first detection portion 111, and the second detection portion 112 is in contact with the connection surface 1222a. The flexible absorbent member 16 and the second detection portion 112 housed in the second sub-cavity 1223b are stably connected through the elastic compression of the flexible absorbent member 16. The second detection portion 112 increases the contact area between the electrode 11 and the flexible absorbent member 16, thereby achieving stable conduction of electrical signals between the conductive medium and the electrode 11.

[0111] Furthermore, in one embodiment of the present application, the package 122 includes a first connecting portion 1221 and a second connecting portion 1222, wherein the first connecting portion 1221 has a first sub-cavity 1223a, and the first connecting portion 1221 and the cover 121 are magnetically connected via the first magnetic component and the second magnetic component. Before using the electrode device 10, the cover 121 and the package 122 can be disassembled, placing the electrode device 10 in the separated state, and the conductive medium can be injected into the first sub-cavity 1223a, allowing the flexible absorbent member 16 to absorb the conductive medium. After the conductive medium is injected, the cover 121 and the package 122 are connected, placing the electrode device 10 in the fixed state, and the electrode device 10 can be used. The electrode device 10 can be added with the conductive medium without having to immerse the entire device in the conductive medium, further achieving the technical effect of conveniently and hygienically adding the conductive medium. Furthermore, when the conductive medium of the electrode device 10 is insufficient during use, the cover 121 and the enclosure 122 can be removed, placing the electrode device 10 in the separated state, and the conductive medium can be injected into the first sub-cavity 1223a, allowing the flexible absorbent member 16 to absorb the conductive medium, thereby completing the addition of the conductive medium. The electrode device 10 allows for convenient and quick addition of the conductive medium during use, extending the single-use duration of the electrode device 10 and making it suitable for long-term electrical signal monitoring and electrical stimulation therapy.

[0112] Furthermore, the package body 122 can be, but is not limited to, a structure with two open ends, wherein one end of the package body 122 is open for accommodating the conductive medium in contact with the target object, and the other end is open and covered with the cover body 121. The flexible absorbent member 16 is accommodated in the first accommodating cavity 1223 and protrudes toward the side of the first accommodating cavity 1223 that is away from the second accommodating cavity 1211g. The portion of the flexible absorbent member 16 that protrudes toward the side of the first accommodating cavity 1223 that is away from the second accommodating cavity 1211g abuts against the skin of the target object when the electrode device 10 is in use. The flexible absorbent member 16 is stably connected to the skin of the target object through elastic extrusion to achieve stable conduction of electrical signals between the conductive medium and the target object.

[0113] Furthermore, in one embodiment of the present application, the end of the second detection portion 112 close to the target object may also include a bend. The bend is formed by the second detection portion 112 bending toward one side of the flexible water-absorbing member 16 and the covering member 17. The bend abuts against the flexible water-absorbing member 16, and the flexible water-absorbing member 16 is elastically squeezed and stably connected to the bend, thereby ensuring that the flexible water-absorbing member 16 is stably connected to the covering body 122 and is not easily detached. The bend can prevent the flexible water-absorbing member 16 from detaching from the covering body 122 during use, thereby preventing poor contact with the second detection portion 112 and affecting the stability of electrical signal transmission.

[0114] The electrode assembly 10 also includes a covering 17, which is a mesh structure and may be, but is not limited to, a polypropylene mesh structure. The covering 17 and the flexible absorbent member 16 may be, but is not limited to, heat-pressed. The covering 17 encases the flexible absorbent member 16 and is positioned between the flexible absorbent member 16 and the second inner wall surface 1222b, as well as between the flexible absorbent member 16 and the target object during use. The covering 17 prevents the flexible absorbent member 16 from directly contacting the target object's skin surface, preventing the flexible absorbent member 16 from squeezing against the target object's skin during wear, which could cause the conductive medium to leak out and cause a wet sensation, thereby improving the wearing comfort of the electrode assembly 10. Furthermore, the covering 17 prevents the conductive medium in the flexible absorbent member 16 from being squeezed and rapidly leaking out, which could result in the need for frequent additions of the testing medium during testing. This improves the utilization rate of the conductive medium and the efficiency of the electrode assembly 10 during testing.

[0115] In summary, the technical solution of this embodiment utilizes a flexible absorbent member 16 provided on the electrode assembly 10 to absorb saline and contact the subject's scalp and conductive components, thereby collecting EEG signals. The inclusion of a covering member 17 improves wearing comfort and prevents rapid water loss from affecting electrical signal transmission.

[0116] Please refer again Figure 4 、 Figure 5 、 Figure 6 and Figure 11 Furthermore, in one embodiment, the cover body 121 has a second accommodating cavity 1211g, and the second accommodating cavity 1211g is connected to the first accommodating cavity 1223 and communicates with the outside.

[0117] The cover 121 has a second accommodating cavity 1211g connected to the first accommodating cavity 1223 and in communication with the outside world, creating a path between the electrode holder assembly 12 and the outside world. During use, if the conductive medium within the electrode assembly 10 is insufficient, conductive medium can be injected into the second accommodating cavity 1211g to replenish it. This second accommodating cavity 1211g allows for convenient and quick replenishment of the conductive medium without having to disassemble the cover 121 and the enclosure 122, leaving the electrode assembly 10 in the separated state.

[0118] When the electrode device 10 is used in an EEG electrode cap to detect the electrical signal of the target object, multiple electrode devices 10 perform electrical signal detection at the same time; when the electrode device 10 is used in an EEG electrode cap to give electrical stimulation to the target object, multiple electrode devices 10 perform bioelectric stimulation treatment at the same time. At this time, it is easy for multiple electrode devices 10 to lack conductive medium at the same time. The second accommodating cavity 1211g does not need to disassemble the cover body 121 and the package body 122 to make the electrode device 10 in the separated state to replenish the conductive medium, which greatly improves the speed of replenishing the conductive medium and solves the technical problem that multiple electrode devices 10 lack conductive medium at the same time and are difficult to replenish quickly.

[0119] Furthermore, during use, the cover 121 and the package 122 are disassembled, resulting in the separation of the electrode device 10 from the cap. During use, when the cover 121 and the package are disassembled to add a conductive medium, the testing personnel or treatment operator needs to assist in fixing the package 122 in contact with the skin of the target object's detection site or the electrical stimulation treatment site while injecting the conductive medium into the first accommodating cavity 1223. After the injection, the cover 121 and the package 122 are connected. During this process, the package 122 needs to be kept in contact with the skin of the target object's detection site or the electrical stimulation treatment site throughout the entire process, making the operation complicated and tedious. When the electrode device 10 is used in an EEG electrode cap to detect the electrical signal of a target object or when the electrode device 10 is used in an EEG electrode cap to give electrical stimulation to a target object, the second accommodating cavity 1211g can be installed corresponding to the through hole of the cap body, so that the first accommodating cavity 1223 is connected to the outside world, achieving the technical effect of replenishing the conductive medium without disassembling the cover body 121 and the package body 122 so that the electrode device 10 is in the separated state, thereby avoiding the tedious operation of opening the cover body 121 to replenish the conductive medium.

[0120] In summary, in the electrode device 10 provided in the embodiment of the present application, the cover 121 has a second accommodating cavity 1211g to connect the first accommodating cavity 1223 with the outside world. This allows the electrode device 10 to be refilled through the second accommodating cavity 1211g when the conductive medium is exhausted or nearly exhausted during use, without pausing the device. This further enables efficient use of the electrode device 10 and increases the duration of a single use of the electrode device 10.

[0121] Please refer again Figure 2 and Figure 3 Also see Figure 13 and Figure 14 , Figure 13 This is a schematic structural diagram of an EEG electrode cap according to one embodiment of the present invention; Figure 14 yes Figure 13 The schematic diagram of the cross-sectional structure of the EEG electrode cap along the CC line is shown. One embodiment of the present application provides an EEG electrode cap 1, which includes a cap body 20 and at least one electrode device 10. Please refer to the previous description of the electrode device 10 and will not be repeated here. The cap body 20 has an outer surface 202 and an inner surface 201 that are arranged opposite to each other, and the cap body 20 also has at least one cap body through hole 21 that passes through the outer surface 202 and the inner surface 201. The electrode device 10 is arranged corresponding to the cap body through hole 21, the cover body 121 is located on the outer surface 202 of the cap body 20, and the enclosure 122 is located on the inner surface 201 of the cap body 20.

[0122] The EEG electrode cap 1 includes a cap body 20, which can be elastically deformed according to the shape of the target subject's head. The cap body 20 can be elastically worn on the target subject's head. The cap body 20 has an outer surface 202 and an inner surface 201 that are arranged opposite to each other. When in use, the inner surface 201 contacts the target subject's head. The cap body 20 can be manufactured in an integrated molding method to reduce production costs; it can also be assembled in multiple pieces to freely determine the shape of the cap body 20 to adapt to different target subjects.

[0123] The cap body 20 also has at least one cap body through hole 21 that passes through the outer surface 202 and the inner surface 201. When the EEG electrode cap 1 is used to detect the electrical signal of the target object, the cap body through hole 21 is set at the EEG signal detection point corresponding to the target object's head when the cap body 20 is worn on the target object's head; when the EEG electrode cap 1 is used to give electrical stimulation to the target object, the cap body through hole 21 is set at the EEG stimulation treatment point corresponding to the target object's head when the cap body 20 is worn on the target object's head. The electrode device 10 is arranged corresponding to the cap body through hole 21. The first accommodating cavity 1223, the cap body through hole 21 and the second accommodating cavity 1211g are arranged correspondingly to form a channel connected to the outside world, and the conductive medium can be replenished through the channel connected to the outside world.

[0124] The cover 121 is located on the outer surface 202 of the cap body 20, and the enclosure 122 is located on the inner surface 201 of the cap body 20. The projected area of the cap body through hole 21 on the inner surface 201 should be smaller than the projected area of the enclosure 122 on the inner surface 201, and the projected area of the cap body through hole 21 on the outer surface 202 should be smaller than the projected area of the cover 121 on the outer surface 202, so that the electrode device 10 can be fixed to the cap body 20. Furthermore, the projected area of the cap body through hole 21 on the inner surface 201 can be greater than or equal to the projected area of the first inner wall surface 1221c on the inner surface 201, so that the portion of the first detection portion 111 protruding from the first connection portion 1221 can extend out of the cap body through hole 21. Furthermore, the area of the cap body through hole 21 projected on the outer surface 202 can be larger than the area of the second accommodating cavity 1211g projected on the outer surface 202, so that the limiting groove 1211e can accommodate the part of the electrode 11 protruding from the first connecting part 1221 and extending out of the cap body through hole 21.

[0125] In summary, in the EEG electrode cap 1 provided in the embodiment of the present application, the EEG electrode cap 1 includes a cap body 20 having at least one cap body through hole 21, and at least one electrode device 10 arranged corresponding to the cap body through hole 21. The cap body 20 has an inner surface 201 and an outer surface 202. When installed, the cover body 121 is located on the outer surface 202, and the package body 122 is located on the inner surface 201. The electrode device 10 and the cap body 20 are detachably connected through the first magnetic component and the second magnetic component. Compared with the detachable method using threads or snaps, the cover body 121 and the package body 122 in the electrode device 10 provided in the embodiment of the present application are detached using the first magnetic part 13 and the second magnetic part 14, which avoids the cover body 121 and the package body 122 causing friction or extrusion on the cap body 20 during installation and disassembly, thereby damaging the cap body 20.
