With the increase of user demand, EEG detection is widely used in the field of smart head wearable physiological signal monitoring devices as a way to judge the activity state of the brain.

[0003] Most of the existing EEG detection headbands use electrode caps for EEG collection. The electrode caps can be in cap style or silicone strip style. This style will have fixed openings at multiple collection positions, and different types of collection electrodes can be replaced. Since the opening of the electrode cap is fixed and has no adjustment capability, or the size of the electrode cap can only be adjusted within a small range depending on the toughness of the material itself, this type of electrode collection device cannot be adapted to patients with all head shapes and head circumferences. In this case, multiple sizes need to be designed according to different types of patients, increasing production and management costs. At the same time, the electrode cap also has the problems of strong tightness and poor air permeability, which affects the user's comfortable long-term wearing, especially in sleeping scenes.

In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0039] According to the utility model, a smart head wearable physiological signal monitoring device is provided. Figures 1 to 10 As shown, the intelligent head wearable physiological signal monitoring device is used for collecting human brain waves. Compared with the existing technology, the intelligent head wearable physiological signal monitoring device can fully adapt to different brain types of different people through multiple adjustment parts. While ensuring the contact quality of the electrode, that is, the quality of the collected signal, it reduces the difficulty of wearing and increases the comfort of wearing. It has a wide range of application scenarios. At the same time, the existing headband cannot meet the effectiveness of both wearing comfort and signal collection quality in the sleeping scene. The intelligent head wearable physiological signal monitoring device not only ensures the quality of signal collection, but also takes comfort into account, and is fully adapted to the sleeping scene. The intelligent head wearable physiological signal monitoring device can include a mainboard structure 1, a first adjustment part 2, a second adjustment part 3, and a third adjustment part 4.

[0040] In the following description, reference will be made to Figures 1 to 10 The detailed structures of the main board structure 1, the first adjustment part 2, the second adjustment part 3 and the third adjustment part 4 of the intelligent head wearable physiological signal monitoring device are specifically described.

[0041] like Figure 1 and Figure 2 As shown, in the embodiment, the mainboard structure 1 can be used as the control system and signal collection and feedback system of the smart head wearable physiological signal monitoring device. Specifically, the mainboard structure 1 can be formed into a rectangular parallelepiped structure with a certain thickness for accommodating the mainboard circuit, signal components and electrical connection lines, etc. The side of the rectangular parallelepiped structure facing the user (i.e., Figure 2 The side with the block electrode 11 as shown is formed into an arc surface. When the user wears the smart head wearable physiological signal monitoring device, the arc surface fits the user's forehead, so the block electrode 11 also fits the user's forehead, and signal collection can be performed. It should be noted here that in the embodiment, the specific structure inside the mainboard structure 1 can use, for example, the control circuit of the headband in the prior art. Those skilled in the art can specifically select the internal structure of the mainboard structure 1 according to the prior art, and can achieve signal collection and feedback, which will not be repeated here.

[0042] like Figure 1 and Figure 2 As shown, in the embodiment, the first adjustment part 2 can be formed into a ring shape, which is used to surround and fit the back of the user's head tightly, thereby forming the wearable body of the intelligent head wearable physiological signal monitoring device. Specifically, the two ends of the first adjustment part 2 are adjustably connected to the main board structure 1. In order to facilitate the adaptation to the different brain shapes of different users, the two ends of the first adjustment part 2 can adjust the length to increase the adaptability. The two ends of the first adjustment part 2 are respectively connected to the main board structure 1. Figure 1The first adjustment part 2 is arranged along the first circumferential direction, where the first circumferential direction refers to a circle starting from the forehead of the human brain and surrounding the back of the brain horizontally, so that the first adjustment part 2 can be adapted according to different brain shapes of different users to make it comfortable to wear.

[0043] like Figure 1 and Figure 2 As shown, in the embodiment, the second adjustment part 3 can be formed into a semi-circular shape, which is used to surround and fit closely to the top of the user's head, and cooperate with the first adjustment part 2 to achieve fit in two directions of the human brain. The first end of the second adjustment part 3 is connected to the main board structure 1, and the second end of the second adjustment part 3 is connected to the first adjustment part 2. Specifically, the first end of the second adjustment part 3 is connected to the main board structure 1. Figure 1 At the top shown, the second end of the second adjustment portion 3 is connected to the middle of the first adjustment portion 2. The second adjustment portion 3 can be arranged to be adjustable in length along the second circumferential direction, where the second circumferential direction refers to a circle starting from the forehead of the human brain and surrounding the top of the head longitudinally. In this way, the second adjustment portion 3 can be fully adapted to different brain shapes of different users by adjusting the length, so that it is comfortable to wear.

[0044] like Figure 1 and Figure 2 As shown, in the embodiment, the third adjustment portion 4 can be formed into a quarter ring shape, which is used to surround and fit the rest of the user's head, and the most optimal detection position can be specifically selected according to the standards issued by the American Academy of Sleep Medicine (AASM). The third adjustment portion 4 is arranged on the second adjustment portion 3, and the two ends of the third adjustment portion 4 are arranged with adjustable length along the third circumferential direction. The third circumferential direction here can be a circle longitudinally surrounding the top of the human brain. In this way, the third adjustment portion 4 can place the detection electrode at the optimal collection point by adjusting the length, thereby achieving excellent transmission of EEG signals.

[0045] like Figure 1 and Figure 2 As shown, in the embodiment, the first adjustment part 2, the second adjustment part 3 and the third adjustment part 4 can all form a belt-like structure with a certain width. The belt-like structure with a certain width can avoid the discomfort caused by excessive squeezing of the human brain when worn. At the same time, only these belt-like structures can ensure the breathability when worn. In addition, due to the small structure, it is also easy to take, wear and clean. Therefore, it is applicable to more scenarios.

[0046] like Figure 1 and Figure 2As shown, in the embodiment, the main board structure 1, the second adjustment part 3 and the third adjustment part 4 are all provided with detection electrodes. By providing the detection electrodes and the second adjustment part 3 and the third adjustment part 4 can adjust the electrode positions, the user can also wear the smart head wearable physiological signal monitoring device at home. Compared with the headband in the form of an electrode cap in the prior art, the user can wear the smart head wearable physiological signal monitoring device alone, and can adjust the length of the first adjustment part 2, the second adjustment part 3 and the third adjustment part 4 to ensure the quality of signal acquisition while wearing comfortably.

[0047] Preferably, if Figures 1 to 6 As shown, in the embodiment, the third adjustment part 4 is arranged on the second adjustment part 3 through the first knob part 6; the first knob part 6 can adjustably connect the third adjustment part 4 to the second adjustment part 3. The first knob part 6 can include a first-stage knob assembly and a second-stage knob assembly, the second adjustment part 3 is arranged to be adjustable in length through the first-stage knob assembly, and the third adjustment part 4 is arranged to be adjustable in length through the second-stage knob assembly. In this way, the second adjustment part 3 and the third adjustment part 4 can be adjusted in two circumferential directions through the first knob part 6, with a simple structure, convenient operation, and convenient for users to wear.

[0048] Preferably, if Figures 1 to 6 As shown, in an embodiment, the second adjustment portion 3 may include a fixing member 301 and a sliding member 302. The sliding member 302 may be slidably disposed on the fixing member 301. The fixing member 301 may be formed as an internally hollow long strip structure with an arc. The sliding member 302 slides in the internally hollow fixing member 301. The sliding member 302 retracts into the fixing member 301, and the length of the second adjustment portion 3 is shortened. The sliding member 302 extends out of the fixing member 301, and the length of the second adjustment portion 3 is increased. The retraction and extension of the sliding member 302 can be adjusted by a first-stage knob assembly. Specifically, a first rack 303 is formed on the side of the sliding member 302, a waist-shaped hole is opened in the middle of the sliding member 302, and a first rack 303 is formed on one side of the waist-shaped hole; the first-level knob assembly may include a first rotating rod, and the two ends of the first rotating rod are respectively formed as a first rotating knob 601 and a first gear 602, and the first gear 602 is in contact with the first rack 303. When the user rotates the first rotating knob 601, the first gear 602 drives the first rack 303, so that the sliding member 302 can be slidably arranged on the fixing member 301 through the cooperation of the first rack 303 and the first gear 602. The cooperation of the gear and the rack saves time and effort when the user adjusts the length, and avoids the cumbersome length adjustment of the existing structure. Compared with the elastic retractable belt in the prior art, the gear structure can ensure that the smart head wearable physiological signal monitoring device does not fall off when the user wears it, and will not tighten the user's head too much to cause discomfort, and is easy to adjust.

[0049] Preferably, if Figure 4 As shown, in the embodiment, the third adjustment part 4 may include a first telescopic cantilever 401 and a second telescopic cantilever 402, the first telescopic cantilever 401 and the second telescopic cantilever 402 both start from the first knob part 6 and extend to both sides respectively, the first telescopic cantilever 401 and the second telescopic cantilever 402 are arranged facing each other, and the second rack 403 and the first insertion position 404 are formed on both sides of the end of the first telescopic cantilever 401 facing the second telescopic cantilever 402, and the third rack 405 and the second insertion position are formed on both sides of the end of the second telescopic cantilever 402 facing the first telescopic cantilever 401 (due to the viewing angle, not shown, the second insertion position structure is the same as the first insertion position 404 structure); the second rack 403 and the third rack 405 extend outward from the ends of the first telescopic cantilever 401 and the second telescopic cantilever 402 respectively, and the two are moved by the second-stage knob assembly. The second-level knob assembly may include a second rotating rod, which is inserted into the first rotating rod. The first rotating rod and the second rotating rod are sleeved together, and the user can adjust the length in two directions at one position, which is easy to operate and saves time and effort. The two ends of the second rotating rod are respectively formed as a second rotating knob 603 and a second gear 604, and the second gear 604 is respectively connected to the second rack 403 and the third rack 405. When the second rotating knob 603 is screwed, the second rack 403 can be inserted into or away from the second insertion position, and the third rack 405 can be inserted into or away from the first insertion position 404. Through the cooperation of the gear and the rack, the user can easily adjust the length of the third adjustment part 4, so that the detection electrodes located at the ends of the first telescopic cantilever 401 and the second telescopic cantilever 402 are at the best point for detecting human brain signals, so as to better collect brain electrical signals. In addition, the integrated second rotating rod and the first rotating rod can save space, reduce structural parts, reduce weight, and achieve comfort and convenience in wearing. Users can wear it by themselves without the accompaniment of professionals (such as doctors). The application scenarios are increased and are not limited to hospitals.

[0050] Preferably, if Figure 4 As shown, in the embodiment, the first telescopic cantilever 401 and the second telescopic cantilever 402 can both be elastic, and the connecting piece formed with the second rack 403 and the third rack 405 can be made of a soft metal material, such as soft iron or stainless steel formed into a thin sheet, so that the first telescopic cantilever 401 and the second telescopic cantilever 402 can be elastic and comfortable for the user to wear.

[0051] Preferably, if Figure 5 and Figure 6As shown, in the embodiment, the first knob portion 6 is slidably disposed on the fixing member 301. The first knob portion 6 includes a housing and a moving member 607, and the housing may include an upper shell 605 and a lower shell 606, and the upper shell 605 and the lower shell 606 are mutually buckled, and the above-mentioned first-level knob assembly and the second-level knob assembly are both arranged inside the housing, and the moving member 607 is also arranged inside the housing, so that the moving housing can move the first knob portion 6, thereby achieving the adjustment of the overall position. Specifically, the fifth rack 305 is formed on both sides of the fixing member 301. Although the brain shapes of different people are different, they are all within a controllable range. Therefore, the adjustment range of the first knob portion 6 can be small and appropriate, and does not need to be too large, so the length of the fifth rack 305 is short. The moving member 607 is formed with fixing holes at both ends, and a protruding block is formed in the middle, which can be clamped on the fifth rack 305. The upper shell 605 is provided with multiple latches 6052. Through the cooperation of multiple latches 6052 and the fixing holes, the moving member 607 is fixed to the upper shell 605. In this way, the user can push the shell to realize the movement of the moving member 607 on the fifth rack 305, so as to achieve adjustment. Since the first knob part 6 needs to have a high fixity with the fixing member 301, the moving member 607 and the fifth rack 305 do not adopt the matching form of rack and gear, but use the form of clamping. In this way, the first knob part 6 can adjust three dimensions in total, the first is the position of the first knob part 6 itself on the fixing member 301, the second is the length of the second adjustment part 3, and the third is the length of the third adjustment part 4. Integrating the adjustment of multiple dimensions in the first knob part 6 is convenient for the user's operation while reducing weight and comfortable to wear. In addition, since the first rotating rod and the second rotating rod are passed through the fixing member 301 , the fixing member 301 needs to be provided with a waist-shaped hole to facilitate the passing of the first rotating rod and the second rotating rod and the movement of the first knob portion 6 .

[0052] Preferably, if Figures 1 to 8 As shown, in the embodiment, the fixing member 301 and the third adjustment part 4 are made of hard materials, and the sliding member 302 and the first adjustment part 2 are made of soft materials. The fixing member 301 and the third adjustment part 4 need to ensure the hardness when worn to ensure the contact quality of the detection electrode. Since the fixing member 301 and the third adjustment part 4 are located in the front of the human brain and the top of the head, the hard material will not affect the comfort; the sliding member 302 and the first adjustment part 2 are located in the back and side of the human brain. These parts will be between the human brain and the pillow during sleep, so soft materials are used to improve comfort. Preferably, the hard material can be, for example, ABS (acrylonitrile-butadiene-styrene copolymer), and the soft material can be, for example, soft rubber TPU.

[0053] Preferably, if Figure 7As shown, in the embodiment, both ends of the first adjustment part 2 are adjustably connected to the main board structure 1 through the second knob part 7, and both ends of the first adjustment part 2 are formed with a fourth rack 201. Specifically, both ends of the first adjustment part 2 are provided with a waist-shaped hole, and a fourth rack 201 is formed on one side of the waist-shaped hole. The second knob part 7 may include a third rotating rod, and both ends of the third rotating rod are respectively formed as a third rotating knob 701 and a third gear 702. The third gear 702 drives the fourth rack 201 and then drives the first adjustment part 2 to adjust the length.

[0054] Preferably, if Figure 1 and Figure 2 As shown, in an embodiment, the intelligent head wearable physiological signal monitoring device may further include a fourth adjustment part 5, which is arranged on the second adjustment part 3, and the two ends of the fourth adjustment part 5 are arranged along the fourth circumferential direction with adjustable length; the structure and adjustment method of the fourth adjustment part 5 may be the same as the third adjustment part 4, specifically, the fourth adjustment part 5 may include a third telescopic cantilever and a fourth telescopic cantilever, and the third telescopic cantilever and the fourth telescopic cantilever are arranged facing each other; the third telescopic cantilever and the fourth telescopic cantilever are arranged on the second adjustment part 3 with adjustable length through the third knob part 8. According to the EEG detection standard issued by the American Academy of Sleep Medicine (AASM), the head has six clear detection positions, and the additional fourth adjustment part 5 can increase the effectiveness of EEG detection.

[0055] Preferably, if Figures 1 to 8As shown, in an embodiment, the detection electrode may include a block electrode 11, a columnar electrode 10 and a comb electrode 9. The block electrode 11 is arranged on the main board structure 1. The block electrode 11 fits the forehead of the human brain. The number of block electrodes 11 can be, for example, three, which can meet the requirements of detecting the brain wave signal of the forehead of the human brain. The columnar electrode 10 can be arranged at the ends of the third adjustment part 4 and the fourth adjustment part 5, specifically at the ends of the first telescopic cantilever 401, the second telescopic cantilever 402, the third telescopic cantilever and the fourth telescopic cantilever. Since the detection position of the ends of these four is the top of the human brain, the top of the human brain has more hair, and the detection electrode fits the human brain skin as the best detection position, therefore, the columnar electrode 10 with a certain length can pass through the hair of the human brain and fit the skin to achieve the best EEG acquisition. The comb electrode 9 can be arranged in the second adjustment part 3, and is used to detect the electrode at the back of the human brain. Specifically, the second end of the second adjustment part 3 may be formed with an electrode mounting plate 12, and the number of comb-shaped electrodes 9 is multiple, and multiple comb-shaped electrodes 9 are arranged on the electrode mounting plate 12. In the sleeping scene, since the back of the human brain often squeezes the electrode, the detection electrode at this position is designed to be comb-shaped, that is, extending from the middle of the detection electrode to both ends, and having multiple tooth-shaped structures at both ends, the tooth-shaped structures have a bending angle, and the bending angle fits the back of the human brain. The tooth-shaped structures can also be penetrated by the hair at the back of the human brain. On the basis of ensuring the detection quality, the comfort of wearing, especially in the sleeping scene, is improved. At the same time, the comb-shaped electrode 9 has a bending angle and elasticity. When the comb-shaped electrode 9 is pressed, the comb-shaped electrode 9 can be flattened, and the detection quality can also be guaranteed. The electrode mounting plate 12 can meet the installation of the comb-shaped electrode 9 and reduce the pressure here, so as to avoid discomfort caused by excessive pressure on the back of the human brain. In addition, it should be noted that the above-mentioned detection electrodes are all electrically connected to the main board structure 1. The electrical connection method can be, for example, using an electrical connection wire, which can pass through the hollow fixing part 301. In order to ensure sleeping comfort, the connection method of the comb-shaped electrode 9 can additionally set an electrical connection wire, and the electrical connection wire is connected to the main board structure 1 through the outside of the smart head wearable physiological signal monitoring device.

[0056] Preferably, if Fig. 9 and Fig.10As shown, in an embodiment, the first knob portion 6 may further include a clamping piece 608. When the first-stage knob assembly and the second-stage knob assembly are passed through the shell, the clamping piece 608 is arranged at the bottom of the first-stage knob assembly and abuts the shell. The upper shell 605 may be formed with a plurality of positioning grooves 6051 and a plurality of latches 6052. The clamping piece 608 may be formed with a positioning bead 6081 and a through hole 6082. When the first-stage knob assembly and the second-stage knob assembly are screwed, the positioning bead 6081 is engaged with the positioning groove 6051, thereby locking the position and preventing the gear and rack structure from moving. When the first-stage knob assembly and the second-stage knob assembly are passed through the shell, the latch 6052 is inserted into the fixing hole of the moving piece 607, and the second-stage knob assembly fixes the clamping piece 608 through the through hole 6082.

For example, in the hospital scenario, the doctor can help the user wear and ensure that each detection electrode is located at the correct and appropriate detection point according to the best point and situation of EEG detection to ensure the collection of EEG signals. When wearing, the first adjustment part 2, the second adjustment part 3, the third adjustment part 4, the fourth adjustment part 5 and the first knob part 6 can be adjusted to meet the wearing of different brain types of different users. When the user uses the smart head wearable physiological signal monitoring device at home, he can check the best detection point by the doctor's notice or by himself. When wearing, it is necessary to ensure that each detection electrode is located at the correct and appropriate detection point. The length of each position is adjusted by the first knob part 6, the second knob part 7 and the third knob part 8, so as to adapt to his own brain, ensure comfort and avoid falling. In the sleep scene, due to the cooperation of the columnar electrode 10, the comb electrode 9 and the block electrode 11, the quality of the EEG detection signal can be guaranteed. At the same time, the smart head wearable physiological signal monitoring device has both hard and soft materials, which can fully adapt to the sleep scene and ensure comfort.
