Description

Technical Field

[0001] Specifically, this invention relates to an auxiliary device for automatic scanning and localization detection based on electroencephalography (EEG). Background Technology

[0002] Electroencephalography (EEG) is a graphical representation of the brain's spontaneous bioelectric potentials recorded through the scalp using sophisticated electronic instruments. It records the spontaneous, rhythmic electrical activity of brain cell groups via electrodes and is one of the most important and irreplaceable diagnostic tools for epilepsy. EEG primarily includes video EEG, ambulatory EEG, and conventional EEG. Figure 3 Types.

[0003] During an electroencephalogram (EEG) examination, medical staff attach multiple skin electrodes to the patient's scalp using conductive gel to collect bioelectrical signals. These electrodes need to be secured. Current technology typically uses a standard mesh headgear to fix the electrodes in place to ensure accurate and normal examination. However, EEG examinations for epilepsy often last from two to 24 hours. A standard mesh headgear only serves the function of securing the electrodes and neglects the fact that prolonged wear, especially the pressure from the edges of the headgear on the patient's forehead and ears, can cause pain and affect the patient's ability to continue the examination. Furthermore, the headgear size is not adjustable, and the same type of headgear... The tightness of the electrodes varies depending on the patient's head size, making it impossible to adjust the tightness to suit different head circumferences. This reduces the patient's experience and satisfaction during the examination, and in severe cases, can cause skin chafing. On the other hand, the sampling potential is fixed, and the position of the sampling electrodes cannot be adjusted according to the patient's head circumference. Medical staff need to adjust the position of the sampling electrodes according to the patient's head circumference, which increases their workload. Furthermore, medical staff need to prepare tethers to store the electrode wires before each installation. The storage of the electrode wires after use often results in tangling, pulling, and displacement of the electrode wires during the patient's examination, affecting the examination results. Summary of the Invention

[0004] In view of the above, the present invention provides an auxiliary device for automatic scanning and localization detection based on electroencephalography (EEG) to solve the problems mentioned in the background art.

[0005] According to the present invention, an auxiliary device for automatic scanning and positioning detection based on electroencephalography (EEG) includes a headband retractable loop that can automatically retract and tighten around a patient's head, and a head cover for EEG detection. The head cover includes a head cover shell and a head cover mesh cap, with the head cover mesh cap housed inside the head cover shell. The headband retractable loop includes a loop shell and a tightness adjustment mechanism. A through-hole annular groove is formed on the upper surface of the loop shell. A set of retraction and extension mechanisms for adjusting the position of the head cover mesh cap is arranged on opposite sides inside the annular groove. The retraction and extension mechanism includes a rotating motor and a rotating rod that adjusts the position of the head cover mesh cap during rotation. The rotating motor is located at one end of the annular groove, and the rotating rod rotates horizontally along the annular groove connected to the rotating end of the rotating motor. The device also includes a tool for scanning the user's external head shape to determine the EEG signal. The head-mounted 3D scanner mechanism for EEG detection includes a semi-circular scanning element that can scan around the user's head, a drive motor, and a rotating shaft. A set of 3D scanning light strips is distributed along the inner side of the semi-circular scanning element. The drive motors are located at both ends of the lower middle part of the ring-shaped outer shell. The semi-circular scanning element is connected to the rotating ends of the drive motors on both sides via the rotating shaft, causing the middle position of the semi-circular scanning element to rotate along the user's head. During the rotation from the front to the back of the ring-shaped outer shell, the 3D scanning light strips scan along the user's head to obtain the specific points required for EEG detection. The head-mounted mesh cap includes a grid track, a groove track, and several sampling electrodes that can move along the groove track. One end of each of the sampling electrodes is connected to a signal connection line, which is connected to the output end of the EEG detector.

[0006] Furthermore, the lower edge of the head cover is provided with a sleeve, and the head cover fits onto the rotating rod. During the horizontal rotation of the rotating rod along the annular groove, when the rotating rod rolls the lower edge of the head cover inward, the head cover tightly clamps the patient's head downward. When the rotating rod rolls the lower edge of the head cover outward, the head cover moves upward away from the patient's head.

[0007] Furthermore, the grid tracks are arranged in a crisscross pattern, forming several squares when combined. The groove tracks are distributed along the diagonals of the squares, and several miniature linear motors are set inside the groove tracks. Several sampling electrodes are respectively set on several corresponding miniature linear motors. The three-dimensional scanning light strip is connected to the input ends of several miniature linear motors, so that the miniature linear motors drive the sampling electrodes to move along the groove tracks to the specific points detected by the three-dimensional scanning light strip.

[0008] Furthermore, the tension adjustment mechanism includes an adjustment belt, a gear motor and a toothed belt respectively located at both ends of the adjustment belt. The toothed belt meshes with the gear of the gear motor through teeth at one end, and the gear motor meshes with the toothed belt to adjust the tension of the adjustment belt.

[0009] Furthermore, both the grid track and the groove track are made of silicone, and each type of grid track and groove track has several units.

[0010] Furthermore, the specific points include a first detection point, a second detection point, and a third detection point. The first detection point corresponds to the front of the forehead, and the second and third detection points correspond to the left and right sides of the forehead, respectively.

[0011] Furthermore, the groove track has detection points on its grid lines that correspond to the first detection point, the second detection point, and the third detection point.

[0012] Furthermore, the plurality of sampling electrodes includes a first, second, and third sampling electrode, and the plurality of micro linear motors includes a first, second, and third micro linear motor. The first, second, and third micro linear motors respectively drive the first, second, and third sampling electrodes to move to the corresponding first detection point, second detection point, and third detection point.

[0013] Furthermore, a soft pad is laid on the inner side of the ring shell that contacts the user's head.

[0014] The auxiliary device for automatic scanning and positioning detection based on electroencephalogram (EEG) of the present invention has a tightness adjustment mechanism that can adjust the tightness of the device when worn by the patient, effectively and reliably fix the skin electrodes, and can be used by patients with different head sizes, making it highly versatile.

[0015] By designing soft pads on the inside of the ring shell, the pressure of the ring shell on the patient's forehead and ears can be reduced, thus reducing the pain experienced by the patient during the examination and preventing skin bruising. This facilitates long-term continuous testing for the patient and improves the patient's experience and satisfaction.

[0016] By connecting several sampling electrodes to a single main signal line, the electrode wires can be quickly stored, reducing the workload of medical staff, improving their efficiency, and preventing the electrode wires from becoming tangled, pulled, or displaced during the patient's examination, which could affect the examination results.

[0017] By setting up a 3D scanner mechanism, a 3D scanning light strip scans along the user's head to obtain specific points required for EEG detection. The 3D scanning light strip is connected to the input ends of several miniature linear motors, which drive the sampling electrodes to move along the grooved track to the specific points detected by the 3D scanning light strip. At the same time, a headband retraction ring is set up, and the headband mesh cap fits onto a rotating rod. As the rotating rod rotates along the annular groove, when the rotating rod rolls the lower edge of the headband mesh cap inward, the headband mesh cap is tightly wrapped around the patient's head. When the rotating rod rolls the lower edge of the headband mesh cap outward, the headband mesh cap moves upward away from the patient's head. This allows the position of the sampling electrodes to be adjusted according to the size of the patient's head circumference. The automated EEG scanning and positioning detection of the sampling electrodes greatly reduces the workload of medical staff and speeds up the EEG detection efficiency. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and some embodiments.

[0026] exist Figures 1-6 The present invention provides an auxiliary device for automatic scanning and positioning detection based on electroencephalography (EEG), including a headband retractable loop 1 that can automatically retract and tighten around the patient's head and a head cover for EEG detection. The head cover includes a head cover shell 2 and a head cover mesh cap 7. In use, the auxiliary device is worn on the user's head, the headband retractable loop 1 is tightened around the patient's head, and the head cover is used for EEG detection.

[0027] In this embodiment, a three-dimensional scanner mechanism is also included for scanning the user's external head shape to determine the head detection points during electroencephalogram (EEG) testing. The three-dimensional scanner mechanism includes a semi-circular scanning element 5 that can scan around the user's head, a drive motor 401, and a rotating shaft 4. A set of three-dimensional scanning light strips 6 are distributed along the inner side of the semi-circular scanning element 5. The drive motor 401 is located at both ends of the lower middle part of the ring shell. The semi-circular scanning element 5 is connected to the rotating ends of the drive motors 401 on both sides through the rotating shaft 4, so that the middle position of the semi-circular scanning element 5 is flipped along the user's head. During the process of flipping from the front side to the back side of the ring shell, the three-dimensional scanning light strips 6 scan along the user's head to obtain the specific points required for EEG testing. The auxiliary device is worn on the user's head. First, the drive motor 401 causes the middle position of the semi-circular scanning element 5 to rotate along the user's head. During the rotation from the front to the back of the ring shell, the three-dimensional scanning light strip 6 scans along the user's head to obtain specific points required for EEG detection, establishing a three-dimensional imaging data model of the user's head shape. The user's head shape imaging data model is then transmitted to the input end of the micro linear motor, which drives the sampling electrode to move along the groove track 702 to the specific points detected by the three-dimensional scanning light strip 6. This allows the position of the sampling electrode to be adjusted according to the size of the patient's head circumference, and the automated scanning and positioning detection of the sampling electrode greatly reduces the workload of medical staff and speeds up the efficiency of EEG detection.

[0028] In this embodiment, the headgear 7 is built inside the head cover shell 2. The headband retractable ring 1 includes a ring shell and a tightness adjustment mechanism. A through annular groove 3 is formed on the upper surface of the ring shell. A set of retraction mechanisms for adjusting the position of the headgear 7 is arranged on both sides of the annular groove 3. The retraction mechanism includes a rotating motor 13 and a rotating rod 15 that adjusts the position of the headgear 7 during rotation. The rotating motor 13 is located at one end of the annular groove 3, and the rotating rod 15 is connected to the rotating end of the rotating motor 13 along the annular groove 3 and rotates horizontally. The lower edge of the headgear 7 is provided with... The sleeve 14, the head cover 7 is fitted onto the rotating rod 15. During the horizontal rotation of the rotating rod 15 along the annular groove 3, when the rotating rod 15 rolls the lower edge of the head cover 7 inwards, the head cover 7 is tightly clamped downwards onto the patient's head. When the rotating rod 15 rolls the lower edge of the head cover 7 outwards, the head cover 7 moves upwards away from the patient's head. The head cover 7 includes a grid track 701, a groove track 702, and several sampling electrodes that can move along the groove track 702. One end of each of the sampling electrodes is connected to a signal connection line 11, which is connected to the output end of the electroencephalogram (EEG) detector. When three... The 3D scanning light band 6 scans along the user's head to obtain specific points required for EEG detection, establishing a three-dimensional imaging data model of the user's head shape. This model is then transmitted to the input of a miniature linear motor, which moves the sampling electrode along the groove track 702 to the specific point detected by the 3D scanning light band 6. Simultaneously, the rotating motor 13 drives the rotating rod 15 to rotate. As the rotating rod 15 rotates along the annular groove 3, it rolls the lower edge of the headgear 7 inward, tightly securing it to the patient's head. This ensures the sampling electrode is in close contact with the specific point, allowing for detection based on the patient's specific location. The position of the sampling electrodes is adjusted according to the size of the patient's head circumference. The automated EEG scanning and positioning detection of the sampling electrodes greatly reduces the workload of medical staff. When the rotating rod 15 rolls the lower edge of the head cover 7 outward, the head cover 7 moves upward away from the patient's head, making it easy to remove the auxiliary equipment for the next patient. This speeds up the EEG detection efficiency. Furthermore, by connecting several sampling electrodes to a single signal connection line 11, the electrode wires can be quickly stored, reducing the workload of medical staff, improving their work efficiency, and preventing the electrode wires from becoming tangled, pulled, or displaced during the patient's examination, which would affect the examination results.

[0029] In this embodiment, the grid tracks 701 are arranged in a crisscross pattern, forming several squares when combined. The groove tracks 702 are distributed along the diagonals of the squares. Several miniature linear motors are arranged within the groove tracks 702, and several sampling electrodes are respectively mounted on the corresponding miniature linear motors. The three-dimensional scanning light strip 6 is connected to the input terminals of the miniature linear motors, causing the miniature linear motors to move the sampling electrodes along the groove tracks 702 to a specific point detected by the three-dimensional scanning light strip 6. The specific point includes a first detection point 20. The system includes a second detection point 19 and a third detection point 21. The first detection point 20 corresponds to the front of the forehead, and the second and third detection points 19 and 21 correspond to the left and right sides of the forehead, respectively. The groove track 702 has detection points on its grid lines corresponding to the first detection point 20, the second detection point 19, and the third detection point 21. The system includes several sampling electrodes, including a first, second, and third sampling electrode 10, and several micro linear motors, including a first, second, and third micro linear motor 24. The first, second, and third micro linear motors 24 respectively... The first, second, and third sampling electrodes 10 are driven to move to the corresponding first detection point 20, second detection point 19, and third detection point 21. When the three-dimensional scanning light band 6 scans along the user's head to obtain the specific points required for EEG detection, a three-dimensional user head shape imaging data model is established. For example, the first detection point 20 corresponds to the front of the forehead, and the second detection point 19 and third detection point 21 correspond to the left and right sides of the forehead, respectively. The user head shape imaging data model of the corresponding detection points is transmitted to the input end of the micro linear motor, so that the first, second, and third micro linear motors 24 drive the first, second, and third sampling electrodes 10 to move to the corresponding first detection point 20, second detection point 19, and third detection point 21, respectively. This allows the position of the sampling electrodes to be adjusted according to the size of the patient's head circumference, and the automatic scanning and positioning detection of the sampling electrodes for EEG is automatically performed. In actual production, multiple detection points such as the fourth and fifth detection points at different positions on the head may also be designed, and a corresponding number of micro linear motors and sampling electrodes may be provided to achieve a more comprehensive and accurate automatic scanning and positioning detection of EEG.

[0030] In this embodiment, the tension adjustment mechanism includes an adjustment belt 16, a gear motor 18 and a toothed belt 17 respectively disposed at both ends of the adjustment belt 16. The toothed belt 17 meshes with the gear of the gear motor 18 through teeth at one end. The gear motor 18 drives the toothed belt 17 through gear meshing, thereby adjusting the tension of the adjustment belt 16. By designing the tension adjustment mechanism, the tightness of the assistive device worn by the patient can be adjusted, effectively and reliably fixing the skin electrode. At the same time, it can be adapted to patients with different head sizes, and has strong universality.

[0031] In this embodiment, both the grid track 701 and the groove track 702 are made of silicone, and there are multiple grid tracks 701 and groove tracks 702. A soft pad 12 is laid on the inner side of the ring shell that contacts the user's head. By designing the soft pad 12 on the inner side of the ring shell, the pressure of the ring shell on the patient's forehead and ears can be reduced, the pain caused by the patient during the examination can be reduced, and the patient's skin can be prevented from being injured. This is conducive to the patient's long-term continuous testing and improves the patient's experience and satisfaction.

[0032] In this embodiment, the sampling electrode is a dry electrode module, which includes a wireless power supply unit, a wireless communication unit, and a data processing unit. This eliminates the need to apply conductive adhesive to the sampling electrode for EEG detection, making the dry electrode module more comfortable and convenient to use. The wireless power supply unit provides power to the sampling electrode, while the wireless communication unit and data processing unit enable signal transmission between the sampling electrode and the EEG detector to assist in completing the EEG detection.

[0033] In this embodiment, the three-dimensional scanning light strip 6 incorporates several photoelectric sensors and a semiconductor laser line light source. The three-dimensional scanning light strip scans along the user's head to obtain specific points required for electroencephalogram (EEG) detection. The collected images of the calibration points clearly distinguish the imaging position of each calibration point. The several photoelectric sensors and semiconductor laser line light source form a ring on the surface of the user's head, realizing automatic scanning of the user's head from top to bottom. Using image processing methods and the user's head shape imaging data model, through data processing and data stitching, the point cloud data of the three-dimensional contour of the user's head shape imaging data model is successfully obtained.

[0034] In this embodiment, the drive motor 401 is a common motor device, such as a 25BYZ series linear motor or a YS7124-0.37KW B5 asynchronous motor.

[0035] In this embodiment, the three-dimensional scanning light strip 6 is a common three-dimensional stereoscopic imaging scanner device, such as the REVOPOINT POP 3 model, the SCANTECH model, etc.

[0036] In this embodiment, the rotary motor 13 is a common rotary motor device, such as the GB / T4831-2016 model, Y160M-4 model rotary motor, etc.

[0037] In this embodiment, the first micro linear motor 22, the second micro linear motor 23, and the third micro linear motor 24 are common micro linear motor devices, such as NEMA8, NEMA17, and NEMA23 models.

[0038] In practical implementation of this invention: the auxiliary device is worn on the user's head. First, the drive motor 401 causes the middle position of the semi-circular scanning element 5 to rotate along the user's head. During the rotation from the front to the back of the ring-shaped outer shell, the three-dimensional scanning light strip 6 scans along the user's head to obtain specific points required for EEG detection, establishing a three-dimensional imaging data model of the user's head shape. For example, the first detection point 20 corresponds to the front of the forehead, and the second detection point 19 and the third detection point 21 correspond to the left and right sides of the forehead, respectively. The imaging data model of the user's head shape at the corresponding detection points is transmitted to the input end of the micro linear motor, causing the first, second, and third micro linear motors 24 to drive the first, second, and third sampling electrodes 10 to move to the corresponding first detection point 20, second detection point 19, and third detection point 21, respectively. This allows the position of the sampling electrodes to be adjusted according to the size of the patient's head circumference, automatically performing EEG scanning and positioning detection of the sampling electrodes. At this time, the control motor 13 drives the rotating rod 15 to rotate. During the rotation of the rotating rod 15 along the annular groove 3, when the rotating rod 15 rolls the lower edge of the head cover 7 inward, the head cover 7 is tightly wrapped around the patient's head, so that the sampling electrode is in close contact with a specific point. This allows the position of the sampling electrode to be adjusted according to the size of the patient's head circumference. The automated EEG scanning and positioning detection of the sampling electrode greatly reduces the workload of medical staff. When the rotating rod 15 rolls the lower edge of the head cover 7 outward, the head cover 7 moves upward away from the patient's head, making it easy to remove the auxiliary equipment for the next patient. This speeds up the EEG detection efficiency. Furthermore, by connecting several sampling electrodes to a single signal connection line 11, the electrode wires can be quickly stored, reducing the workload of medical staff, improving their work efficiency, and avoiding the occurrence of electrode wire tangling, pulling, or displacement during the patient's examination, which would affect the examination results.
