For example, a component or device comprising one or more parts is not limited to the one or more parts listed, but may optionally include one or more parts that are not listed but are inherent to the illustrated product, or one or more parts that it should have based on the described functionality.

[0047] like Figure 1 As shown, Figure 1 A structural schematic diagram of a head-mounted diagnostic and treatment device 100 provided in an embodiment of the present application from one perspective. The head-mounted diagnostic and treatment device 100 is used to monitor and intervene in brain activity, including but not limited to the diagnosis and treatment of depression, the diagnosis and treatment of other emotional diseases, the diagnosis and treatment of brain function diseases, etc. The head-mounted diagnostic and treatment device 100 can be used alone or in combination with other medical equipment. The head-mounted diagnostic and treatment device 100 can be worn for use, specifically worn on the head. The head-mounted diagnostic and treatment device 100 includes a head-mounted structure, at least one active electrode 20, at least one pair of stimulation electrodes 30 and a control module.

[0048] The head-mounted structure includes a headband supporting portion 101 and a frontal lobe wearing portion 102 , and two ends of the frontal lobe wearing portion 102 are respectively connected to opposite sides of the headband supporting portion 101 .

[0049] In one possible embodiment, the headband support portion 101 is detachably connected to the frontal lobe wearing portion 102. In another possible embodiment, the headband support portion 101 is non-detachably connected to the frontal lobe wearing portion 102.

[0050] The headband support portion 101 includes a left side support portion, a top support portion and a right side support portion connected in sequence. The left side support portion, the top support portion and the right side support portion are used to fit the left side curved surface of the head, the top curved surface and the right side curved surface of the head respectively. The left side support portion and the right side support portion are arranged opposite to each other. The left side support portion, the top support portion and the right side support portion can be approximately bent into a U shape. In the following embodiments, the opposite sides of the headband support portion 101 are described as the left side of the headband support portion 101 and the right side of the headband support portion 101 respectively. One end of the frontal lobe wearing portion 102 is connected to the side of the left side support portion of the headband support portion 101 away from the right side support portion of the head, and the other end of the frontal lobe wearing portion 102 is connected to the side of the right side support portion of the headband support portion 101 away from the left side support portion of the head. The frontal lobe wearing portion 102 can be approximately bent into a semicircular arc. In the following embodiments, one end of the frontal lobe wearing portion 102 is described as the left end of the frontal lobe wearing portion 102 , and the other end of the frontal lobe wearing portion 102 is described as the right end of the frontal lobe wearing portion 102 .

[0051] When the head-mounted diagnosis and treatment device 100 is worn, the headband support portion 101 is supported on the head, and the frontal lobe wearing portion 102 is in contact with the frontal lobe area.

[0052] The active electrode 20 is provided on the inner side of the frontal lobe wearing portion 102 for collecting EEG signals at the contact part of the frontal lobe region. In the present application, the active electrode 20 is provided on the inner side of the frontal lobe wearing portion 102, which can be understood as the active electrode 20 being fixed on the inner side of the frontal lobe wearing portion 102. The inner side of the frontal lobe wearing portion 102 is the side of the frontal lobe wearing portion 102 facing the user's head when the head-mounted diagnostic and treatment device 100 is worn and used.

[0053] In one possible embodiment, an active electrode may be provided on the inner side of the frontal lobe wearing portion 102. In another possible embodiment, a plurality of active electrodes may be provided on the inner side of the frontal lobe wearing portion 102, including but not limited to two, three, or four.

[0054] An active electrode refers to an electrode that can realize active signal acquisition by directly contacting the skin without the participation of an additional conductive medium (such as conductive paste, gel, saline, etc.). The active electrode is used to collect EEG signals at the contact point of the frontal lobe area. In other words, when the head-mounted diagnostic and treatment device 100 is worn and used, the active electrode can be set on the frontal lobe wearing part 102 corresponding to the detection point position of the frontal lobe area. Under the control of the control module, the active electrode can reduce the impedance between the skin and the active electrode by transmitting a weak current to realize the acquisition of high-quality active signals. The material of the active electrode is all conductive material, including but not limited to metal conductive material.

[0055] The stimulation electrode 30 is provided on the inner side of the headband support portion 101 and is used to provide electrical stimulation to the contact area of ​​the frontal lobe region. In this application, the stimulation electrode 30 is provided on the inner side of the headband support portion 101, which can be understood as the stimulation electrode 30 being fixed to the inner side of the headband support portion 101. The inner side of the headband support portion 101 is the side of the headband support portion 101 facing the user's head when the head-mounted diagnostic and treatment device 100 is worn and used.

[0056] In one possible embodiment, the number of stimulation electrodes 30 may be one pair. Of course, in other possible embodiments, the number of stimulation electrodes 30 may be two pairs, three pairs, or four pairs.

[0057] The stimulation electrode 30 stimulates the nerves, muscles or tissues at the contact site of the frontal lobe region by transmitting electric current, thereby achieving the purpose of relieving pain, promoting recovery or improving function. That is, the stimulation electrode 30 is used to achieve electrical stimulation therapy.

[0058] The control module is electrically connected to the active electrode 20 and the stimulation electrode 30, and is used to determine the brain function state according to the EEG signal collected by the active electrode 20, and to control the stimulation electrode 30 according to the determined brain function state to form electrical stimulation treatment.

[0059] The control module can be provided in the headband support portion 101, or can be provided in the frontal lobe wearing portion 102. In one possible embodiment, the inner surface of the headband support portion 101 is enclosed to form a receiving space, and the control module is provided in the receiving space of the headband support portion 101. The control module and the active electrode 20 can be directly electrically connected, or indirectly electrically connected. The control module and the stimulation electrode 30 can be directly electrically connected, or indirectly electrically connected. It can be understood that the control module controls the active electrode to collect EEG signals at the contact site, and controls the stimulation electrode 30 to provide electrical stimulation to the contact site.

[0060] The control module controls the active electrode to collect the EEG signal of the contact part. The control module may control the active electrode to collect the EEG signal of the contact part once, or the control module may control the active electrode to collect the EEG signal of the contact part continuously, or the control module may control the active electrode to collect the EEG signal of the contact part intermittently multiple times.

[0061] In an embodiment where the head-mounted diagnostic and treatment device 100 includes multiple active electrodes 20, the control module can control the multiple active electrodes 20 to simultaneously collect EEG signals from the contact parts, or can control the multiple active electrodes 20 to collect EEG signals from the contact parts in sequence.

[0062] The control module controls the stimulation electrode 30 to provide electrical stimulation to the contact part. The control module may control the stimulation electrode 30 to provide electrical stimulation to the contact part once, or the control module may control the stimulation electrode 30 to provide continuous electrical stimulation to the contact part, or the control module may control the stimulation electrode 30 to provide intermittent multiple electrical stimulations to the contact part.

[0063] In an embodiment where the head-mounted diagnostic and treatment device 100 includes multiple pairs of stimulation electrodes 30, the control module can control the multiple pairs of stimulation electrodes 30 to simultaneously provide electrical stimulation to the contact parts, or can control the multiple pairs of stimulation electrodes 30 to provide electrical stimulation to the contact parts in sequence.

[0064] It can be understood that since the active electrode 20 is arranged on the inner side of the frontal lobe wearing part 102 and the stimulating electrode 30 is arranged on the inner side of the headband support part 101, when the head-mounted diagnostic and treatment device 100 is worn and used, the contact part of the active electrode 20 is different from the contact part of the stimulating electrode 30, that is, although the part where the EEG signal is collected and the part where the electrical stimulation is generated are both the frontal lobe area, the specific positions are different.

[0065] The head-mounted diagnostic and treatment device 100 provided in the present application includes a head-mounted structure, at least one active electrode 20, at least one pair of stimulation electrodes 30 and a control module. The head-mounted structure includes a headband support part 101 and a frontal lobe wearing part 102. The two ends of the frontal lobe wearing part 102 are respectively connected to the opposite sides of the headband support part 101. Since the active electrode 20 is arranged on the inner side of the frontal lobe wearing part 102, the EEG signal of the contact part of the frontal lobe area can be collected when the device is worn. The stimulation electrode 30 is arranged on the inner side of the headband support part 101, so the electrical stimulation of the contact part of the frontal lobe area can be achieved when the device is worn. In this way, the control module controls the active electrode 20 and the stimulation electrode 30 to realize the integration of EEG signal collection and electrical stimulation treatment, that is, to realize the integration of brain activity monitoring and intervention. In addition, the wearing method of the head-mounted diagnostic and treatment device 100 is head-mounted, so it has the characteristics of simple wearing and portability.

[0066] In one possible implementation, Figure 2 As shown, Figure 2 This is a schematic structural diagram of the head-mounted diagnostic and treatment device 100 from another perspective provided in an embodiment of the present application. There are multiple active electrodes 20. The at least one pair of stimulation electrodes 30 includes at least one first stimulation electrode 301 and at least one second stimulation electrode 302 spaced apart. The first stimulation electrode 301 is used to electrically stimulate the contact area in the left frontal lobe region, and the second stimulation electrode 302 is used to electrically stimulate the contact area in the right frontal lobe region.

[0067] Among them, multiple active electrodes 20 can be spaced apart along the length direction of the frontal lobe wearing portion 102. In one possible embodiment, multiple active electrodes 20 can be evenly arranged. Of course, in other possible embodiments, multiple active electrodes 20 can be non-uniformly arranged.

[0068] The first stimulation electrode 301 can be located on the left side of the headband support portion 101, that is, between the central axis of the left side support portion and the top support portion of the headband support portion 101. The second stimulation electrode 302 can be located on the right side of the headband support portion 101, that is, between the central axis of the right side support portion and the top support portion of the headband support portion 101. When the head-mounted diagnostic and treatment device 100 is worn and used, the first stimulation electrode 301 corresponds to the left frontal lobe area, that is, is used to contact the F3 area of ​​the brain, and the second stimulation electrode 302 corresponds to the right frontal lobe area, that is, is used to contact the F4 area of ​​the brain.

[0069] In one possible embodiment, there is one first stimulation electrode 301 and one second stimulation electrode 302. Of course, in other possible embodiments, there may be multiple first stimulation electrodes 301 and multiple second stimulation electrodes 302. In this application, the first stimulation electrode 301 and the second stimulation electrode 302 form a pair of stimulation electrodes 30, i.e., the number of first stimulation electrodes 301 is the same as the number of second stimulation electrodes 302.

[0070] This embodiment utilizes multiple active electrodes 20, which collect EEG signals from a greater number of sites, resulting in higher reliability and accuracy. The design of at least one first stimulation electrode 301 and at least one second stimulation electrode 302 allows for electrical stimulation of both the left and right frontal lobe regions. The precise design of the stimulation sites results in higher treatment efficiency.

[0071] In one possible implementation, Figure 3 As shown, the straight line passing through the connection midpoint of the headband support part 101 and the frontal lobe wearing part 102 and parallel to the headband support part 101 is the first straight line, and the line between the connection midpoint of the headband support part 101 and the frontal lobe wearing part 102 and the midpoint of the stimulation electrode 30 is the second straight line, and the angle between the second straight line and the first straight line is 4° to 8°.

[0072] Here, when the first straight line is a straight line passing through the midpoint of the connection between the left side of the headband support portion 101 and the left end of the frontal lobe wearing portion 102 and is parallel to the headband support portion 101, the second straight line refers to the line connecting the midpoint of the connection between the left side of the headband support portion 101 and the left end of the frontal lobe wearing portion 102 and the midpoint of the first stimulation electrode 301. When the first straight line is a straight line passing through the midpoint of the connection between the right side of the headband support portion 101 and the right end of the frontal lobe wearing portion 102 and is parallel to the headband support portion 101, the second straight line refers to the line connecting the midpoint of the connection between the right side of the headband support portion 101 and the right end of the frontal lobe wearing portion 102 and the midpoint of the second stimulation electrode 302.

[0073] In this embodiment, the first straight line can refer to Figure 3 The middle straight line A is shown, and the second straight line can refer to Figure 3 As shown by the straight line B. Optionally, the angle between the second straight line and the first straight line is 4°; or, the angle between the second straight line and the first straight line is 5°; or, the angle between the second straight line and the first straight line is 6°; or, the angle between the second straight line and the first straight line is 8°; or, the angle between the second straight line and the first straight line is 6.63°.

[0074] By making the angle between the second straight line and the first straight line 4° to 8°, it is possible to ensure that the first stimulation electrode 301 is in precise contact with the F3 area of ​​the brain, and that the second stimulation electrode 302 is in precise contact with the F4 area of ​​the brain, thereby achieving high-precision electrical stimulation and avoiding the tediousness of manually adjusting the angle.

[0075] In one possible implementation, Figure 4 As shown, a straight line passing through the midpoint of the connection between the headband support portion 101 and the frontal lobe wearing portion 102 and parallel to the headband support portion 101 is a first straight line, a straight line passing through the midpoint of the connection between the headband support portion 101 and the frontal lobe wearing portion 102 and parallel to the frontal lobe wearing portion 102 is a third straight line, and an angle between the third straight line and the first straight line is 75° to 85°.

[0076] The first straight line is the same as the first straight line in the above embodiment. Figure 4 The middle straight line A is shown, and the third straight line can refer to Figure 4 As shown by the middle straight line C. Optionally, the angle between the third straight line and the first straight line is 75°; or, the angle between the third straight line and the first straight line is 77°; or, the angle between the third straight line and the first straight line is 80°; or, the angle between the third straight line and the first straight line is 82°; or, the angle between the third straight line and the first straight line is 85°.

[0077] By making the angle between the third straight line and the first straight line 75° to 85°, the active electrode 20 can be ensured to be in precise contact with the collection site in the frontal lobe area, thereby achieving high-precision EEG signal collection and avoiding the tediousness of manual angle adjustment.

[0078] In one possible implementation, please refer to Figure 1 and Figure 2 The stimulation electrode 30 is rotatably connected to the headband support part 101.

[0079] It is understandable that the stimulation electrode 30 can rotate relative to the headband support portion 101. Optionally, the first stimulation electrode 301 is rotationally connected to the headband support portion 101, and the second stimulation electrode 302 is fixedly connected to the headband support portion 101; or, the first stimulation electrode 301 is fixedly connected to the headband support portion 101, and the second stimulation electrode 302 is rotationally connected to the headband support portion 101; or, the first stimulation electrode 301 is rotationally connected to the headband support portion 101, and the second stimulation electrode 302 is rotationally connected to the headband support portion 101. The rotational connection includes but is not limited to a rotational connection through the mating of a rotating shaft and an axial hole, or a rotational connection through the mating of a ball head.

[0080] Optionally, the stimulation electrode 30 is rotatably connected to the headband support portion 101 so that the stimulation electrode 30 can rotate relative to the headband support portion 101 in one direction; or, the stimulation electrode 30 is rotatably connected to the headband support portion 101 so that the stimulation electrode 30 can rotate relative to the headband support portion 101 in two directions; or, the stimulation electrode 30 is rotatably connected to the headband support portion 101 so that the stimulation electrode 30 can rotate relative to the headband support portion 101 in at least three directions.

[0081] In a possible embodiment, the stimulation electrode 30 is connected to the head beam support portion 101 by rotation through a ball head. Optionally, the first stimulation electrode 301 is connected to the head beam support portion 101 by rotation through a ball head, and the second stimulation electrode 302 is connected to the head beam support portion 101 by rotation through the cooperation of a rotating shaft and an axial hole; or, the first stimulation electrode 301 is connected to the head beam support portion 101 by rotation through the cooperation of a rotating shaft and an axial hole, and the second stimulation electrode 302 is connected to the head beam support portion 101 by rotation through a ball head; or, the first stimulation electrode 301 is connected to the head beam support portion 101 by rotation through a ball head, and the second stimulation electrode 302 is connected to the head beam support portion 101 by rotation through a ball head. In this embodiment, the stimulation electrode 30 and the head beam support portion 101 are connected by rotation through a ball head, which can realize the rotation of the stimulation electrode 30 relative to the head beam support portion 101 in any direction. Among them, the ball head can be partially or completely embedded in the head beam support portion 101.

[0082] By rotatably connecting the stimulation electrode 30 to the headband support portion 101 , the angle of the stimulation electrode 30 can be adjusted, thereby facilitating matching with users with different head contact curves.

[0083] In one possible implementation, please refer to Figure 5 and Figure 6 The stimulation electrode 30 includes a pressure piece 303, an electrode housing 304, a conductive piece 305, and a sponge 306. The conductive piece 305 is located on the side of the electrode housing 304 facing away from the headband support 101. The pressure piece 303 is located on the side of the electrode housing 304 facing away from the conductive piece 305. The pressure piece 303 is used to transmit pressure to the conductive piece 305. The sponge 306 is located on the side of the conductive piece 305 facing away from the electrode housing 304. The conductive piece 305 and sponge 306 are used to generate electrical stimulation at the contact site.

[0084] Among them, the pressure piece 303 can be a pressure cover. The pressure piece 303 can be in the shape of an arc. The pressure piece 303 is to ensure that the force is transmitted to the components below the electrode shell 304 when the head-mounted diagnostic and treatment device 100 is worn, that is, the force is transmitted to the conductive piece 305 and the sponge 306, so as to ensure that the conductive piece 305 and the sponge 306 are in full contact with the curved surface of the head, and at the same time ensure that the outer periphery of the conductive piece 305 does not turn upward due to the application of pressure, causing the actual contact area with the head to be smaller than the required contact area. Such a design can improve the comfort and effectiveness of electrical stimulation by the stimulation electrode 30. The material of the electrode shell 304 is a non-conductive material, including but not limited to non-conductive silicone, and the electrode shell 304 can ensure that the current flows correctly to the brain. The electrode shell 304 can be in the shape of an arc. The sponge 306 can be used to store water to prevent the stimulation electrode 30 from dripping.

[0085] In a possible implementation, the conductive member 305 includes a conductive electrode 350 and a conductive silicone 351 wrapping the conductive electrode 350 .

[0086] The conductive silicone 351 wrapped around the conductive electrode 350 forms the conductive member 305, facilitating connection between the conductive electrode 350 and the headband support 101 via the ball joint. The conductive silicone 351 also expands the conductive surface. If the entire conductive member 305 were made entirely of hard conductive metal, the conductive surface would be hard and flat, failing to conform to the curved surface of the head.

[0087] In a possible implementation, the head-mounted diagnostic and treatment device 100 further includes at least one sensor, and the control module is electrically connected to the sensor to control the sensor to collect vital sign signals.

In this way, based on EEG signals and vital signs signals, the state of brain activity can be judged more accurately, thereby improving the accuracy of diagnosis.

[0090] In one possible implementation, please refer to Figure 1 and Figure 2 The head-mounted structure also includes a strap wearing portion 103, which is arranged on the side of the headband supporting portion 101 away from the frontal lobe wearing portion 102, and the strap wearing portion 103 and the frontal lobe wearing portion 102 form an annular receiving space.

[0091] One end of the strap wearing portion 103 is connected to the left side support portion of the head beam support portion 101, and the other end is connected to the right side support portion of the head beam support portion 101. The strap wearing portion 103 can be approximately curved into a semicircular arc. In one possible embodiment, the strap wearing portion 103 can be an elastic strap wearing portion 103, that is, the length of the strap wearing portion 103 can be elastically changed. In another possible embodiment, the two ends of the strap wearing portion 103 can be respectively connected to the two sides of the head beam support portion 101 through hooks, and the length of the strap wearing portion 103 can be adjusted by passing through the hooks.

[0107] Among them, step S10, step S20, and step S30 can be performed periodically in a cycle. In one possible embodiment, step S10 can be to obtain the EEG signal collected by an active electrode 20 on the frontal lobe wearing part 102, step S20 can be to determine the brain function state based on the EEG signal collected by an active electrode 20, and step S30 can be to control whether the first stimulation electrode 301 and the second stimulation electrode 302 form electrical stimulation at the same time according to the determined brain function state.
