Description

Technical Field

[0001] This invention relates to the field of sleep monitoring technology, specifically to a sleep monitoring eye mask based on combined EEG and EEG detection. Background Technology

[0002] In the field of sleep monitoring, existing sleep monitoring equipment is mainly divided into professional polysomnography (PSG) systems and portable (home) sleep monitors. Professional PSG systems are mostly used in professional institutions such as hospitals, based on the 10 / 20 EEG position standard (e.g., ...). Figure 1 As shown, the locations of brain electrodes are divided into F (frontal lobe), C (central lobe), T (temporal lobe), P (parietal lobe), O (occipital lobe), and frontal lobe. The information from sleep EEG is mainly concentrated in the F, C, and O frontal lobes. Therefore, when hospitals conduct sleep EEG tests, they will collect the brain waves of each frontal lobe through a professional polysomnography system.

[0003] In the prior art, CN206239412U discloses a wearable sleep monitoring eye mask for combined EEG and EEG detection. The inner side of the eye mask body is fixed with an EEG electrode and a left eye EEG reference electrode. The EEG electrode is located at the corresponding position Fp2, and the left eye EEG reference electrode is located at the corresponding position EOGleft. A main circuit board is fixed in the interlayer of the eye mask body. The main circuit board integrates a signal processing module, a signal separation module, and a wireless transmission module connected in sequence. The signal processing module is connected to the EEG electrode and the left eye EEG reference electrode, respectively. The wireless transmission module communicates wirelessly with an external smart terminal. In addition, the main circuit board is also fixed with a right leg drive electrode, which is located at the corresponding position Fp1 and protrudes from the eye mask body and is connected to the signal processing module.

[0004] While the aforementioned patent solves the problem of EEG signal cancellation, ensuring the effectiveness of the collected signals, and enables combined detection of EEG and EOG, resulting in high-quality sleep monitoring, in actual use, the sensing areas of the eye electrodes differ from person to person due to variations in eye distance. Furthermore, the fixed position of the left eye EEG reference electrode in the aforementioned patent necessitates the use of eye masks of corresponding sizes by different users, significantly reducing its applicability. Even with a suitable eye mask size, misalignment of the left eye EEG reference electrode can still lead to monitoring errors. Additionally, sleep aids are required before sleep monitoring, primarily because the accuracy and effectiveness of sleep monitoring are directly affected by the subject's sleep quality. To ensure the accuracy and reliability of sleep monitoring results, the subject needs sufficient and normal sleep time. Since the aforementioned eye mask requires the user to be asleep before monitoring can begin, it suffers from low monitoring efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention designs a sleep monitoring eye mask based on combined EEG and EEG detection, which can improve the applicability and detection efficiency of the sleep monitoring eye mask.

[0006] The present invention provides the following technical solution: a sleep monitoring eye mask based on combined EEG and EEG detection, comprising: an eye mask body, with adjustable arms fixedly installed at both ends of the eye mask body, a connecting frame rotatably connected to the rear ends of the two sets of adjustable arms, and sleep-aiding headphones rotatably connected to the inner sides of the two sets of connecting frames.

[0007] The main circuit board is fixedly installed inside the main body of the eye mask. The EEG electrode is electrically connected to the left side of the main circuit board. The spacing adjustment frame is fixedly installed below the main circuit board. The EEG reference electrode is fixedly installed on both the left and right ends of the back of the spacing adjustment frame.

[0008] A bidirectional threaded rod is rotatably connected to the top of the inner side of the spacing adjustment frame, and a slide rod is fixedly connected to the bottom of the inner side of the spacing adjustment frame. Both ends of the slide rod are slidably connected to movable seats. The tops of the two sets of movable seats are threadedly connected to the bidirectional threaded rod through connecting sleeves. Both sets of electrooculography reference electrodes are fixedly installed on the outside of the movable seats. A rotating shaft is fixedly connected to the left end of the bidirectional threaded rod, and the rotating shaft extends to the outside of the eye mask body. An adjustment knob is fixedly connected to the end of the rotating shaft located on the outside of the eye mask body. A locking mechanism is installed at the connection between the adjustment knob and the eye mask body.

[0009] Preferably, the locking mechanism includes a fixed gear fixedly connected to the outside of the rotating shaft and located inside the adjusting knob, a pull column slidably connected to the outside of the eye mask body and located outside the fixed gear, and a fixed tooth block fixedly connected to one end of the pull column near the fixed gear.

[0010] Preferably, the fixed tooth block meshes with the fixed gear, and a first spring is sleeved on the outer side of the pull column and on the side of the fixed tooth block away from the fixed tooth block.

[0011] Preferably, a power supply is fixedly installed inside the main body of the eye mask and on the left side of the main circuit board, and a control switch and a charging port are fixedly installed on the top of the main body of the eye mask, with a rubber sealing cover on the outside of the charging port.

[0012] Preferably, the sleep aid headphones, EEG electrodes, EEG reference electrodes, power supply, control switch, and charging port are all electrically connected to the main circuit board.

[0013] Preferably, the inner side of the goggle body is provided with a head monitoring area and an eye monitoring area, and the inner side of both the head monitoring area and the eye monitoring area is fixedly connected with flexible fabric. A nose bridge groove is opened at the bottom of the back of the goggle body.

[0014] Preferably, the bottom ends of both sets of adjusting arms are rotatably connected to the connecting frame via adjusting sleeves. The inner side of the adjusting sleeve is provided with an adjusting groove adapted to the adjusting arm, and a limit block is fixedly connected to one end of each set of adjusting arms located inside the adjusting groove.

[0015] Preferably, wiring holes are provided on the inner side of both sets of connecting frames, and both ends of the inner side of the two sets of connecting frames are rotatably connected to the sleep aid headphones through mounting pins.

[0016] Preferably, the mounting pin has an internal threaded connection to a threaded post, with a second spring fixedly connected to one end of the threaded post inside the mounting pin, and a pressing block fixedly connected to one end of the second spring inside the mounting pin. A retaining ball is movably mounted inside the mounting pin and outside the pressing block.

[0017] Preferably, both the connecting frame and the sleep aid headphones are rotatably connected to the mounting pin, and the inside of the sleep aid headphones has a slot for use with the locking ball.

[0018] The beneficial effects of this invention are:

[0019] 1. Through the design of the main body of the eye mask, after the user wears the main body of the eye mask, the head monitoring area is in contact with the user's forehead, and the eye monitoring area is in contact with the user's eyes. Since the inner sides of the head monitoring area and the eye monitoring area are fixedly connected with flexible fabric, the EEG electrodes are as close as possible to the user's forehead. When the position of the EEG reference electrode is adjusted, the user can also sense the position of the EEG reference electrode moving, so as to correctly adjust the EEG reference electrode to the monitoring position of the user's eyes. This improves the wearing comfort of the main body of the eye mask while ensuring the monitoring accuracy of sleep monitoring.

[0020] 2. Through the design of the spacing adjustment frame and the electrooculogram (EOG) reference electrode, the adjustment knob on the outside of the eye mask body rotates the shaft, which drives the bidirectional threaded rod on the inside of the spacing adjustment frame to rotate. With the connection of the connecting sleeve and the sliding rod, the rotation of the bidirectional threaded rod synchronously drives the two sets of moving seats to move relative to each other. The EOG reference electrode on the outside of the moving seat is located at the eye position. The adjustment stops after the user senses that the EOG reference electrode has moved to the corresponding monitoring position on the eye. This allows different users to make corresponding adjustments when conducting sleep monitoring, thereby improving the applicability of the sleep monitoring eye mask.

[0021] 3. Through the coordinated design of the adjustable arm, connecting frame, and sleep aid headphones, the sleep aid headphones can be adjusted to fit the user's head circumference, allowing them to be positioned near the ears for different users. The sleep aid headphones cover the ears, securing the eye mask to the user's eyes. During sleep monitoring, the sleep aid headphones reduce or eliminate external noise interference, especially in noisy environments. By playing specific sounds, such as white noise or soft music, the headphones help relieve stress on the nervous system and soothe emotions, thus helping users fall asleep more easily. Furthermore, the inner side of the sleep aid headphones is made of soft, skin-friendly materials, such as liquid silicone, ensuring that prolonged wear will not affect ear canal health, helping users fall asleep quickly and significantly improving the efficiency of sleep monitoring.

Detailed Implementation

[0035] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example

[0037] like Figures 2 to 12 As shown, a sleep monitoring eye mask based on combined EEG and EEG detection includes: an eye mask body 1, with adjustable arms 2 fixedly installed at both ends of the eye mask body 1, and connecting frames 3 rotatably connected to the rear ends of the two sets of adjustable arms 2, and sleep aid headphones 4 rotatably connected to the inner sides of the two sets of connecting frames 3. Before the user performs sleep monitoring, the position of the sleep aid headphones 4 is adjusted according to the user's head circumference using the adjustable arms 2, so that the sleep aid headphones 4 can be adjusted to the ears according to different users' head circumferences. Thus, when wearing the eye mask body 1, the sleep aid headphones 4 cover the ears, fixing the eye mask body 1 to the user's eyes.

[0038] In this embodiment, a main circuit board 5 is fixedly installed inside the eye mask body 1. An EEG electrode 6 is electrically connected to the left side of the main circuit board 5. A spacing adjustment frame 7 is fixedly installed below the main circuit board 5. An EEG reference electrode 8 is fixedly installed on both the left and right ends of the back of the spacing adjustment frame 7. When monitoring sleep, after the user wears the eye mask body 1, the spacing adjustment frame 7 is first used to adjust the spacing between the two sets of EEG reference electrodes 8 according to the user's eye distance, so that the positions of the two sets of EEG reference electrodes 8 are close to the monitoring position of the user's eyes.

[0039] In this embodiment, a bidirectional threaded rod 701 is rotatably connected to the top of the inner side of the spacing adjustment frame 7, and a slide rod 702 is fixedly connected to the bottom of the inner side of the spacing adjustment frame 7. Moving seats 703 are slidably connected to both ends of the slide rod 702. The tops of both sets of moving seats 703 are threadedly connected to the bidirectional threaded rod 701 via connecting sleeves 704. Both sets of electrooculography reference electrodes 8 are fixedly installed on the outer side of the moving seats 703. A rotating shaft 705 is fixedly connected to the left end of the bidirectional threaded rod 701, and the rotating shaft 705 extends to the outer side of the eye mask body 1. An adjustment knob 706 is fixedly connected to the end of the rotating shaft 705 located on the outer side of the eye mask body 1. The connection between the adjustment knob 706 and the eye mask body 1 is secured... Equipped with a locking mechanism 707, after the user puts on the eye mask body 1, the rotating shaft 705 is rotated by the adjustment knob 706 on the outside of the eye mask body 1. The rotating shaft 705 drives the bidirectional threaded rod 701 on the inside of the spacing adjustment frame 7 to rotate. With the connection of the connecting sleeve 704 and the sliding rod 702, the two sets of moving seats 703 move relative to each other when the bidirectional threaded rod 701 rotates. The electrooculography reference electrode 8 on the outside of the moving seat 703 is located at the eye position. The adjustment stops after the user senses that the electrooculography reference electrode 8 has moved to the corresponding monitoring position on the eye. This allows different users to make corresponding adjustments when conducting sleep monitoring, thereby improving the applicability of the sleep monitoring eye mask.

[0040] In this embodiment, the locking mechanism 707 includes a fixed gear 708 fixedly connected to the outside of the rotating shaft 705 and located inside the adjusting knob 706. A pull post 709 is slidably connected to the outside of the eye mask body 1 and to the outside of the fixed gear 708. A fixed tooth block 710 is fixedly connected to one end of the pull post 709 near the fixed gear 708. The fixed tooth block 710 meshes with the fixed gear 708. A first spring 711 is sleeved on the outside of the pull post 709 and on the side of the fixed tooth block 710 away from the fixed tooth block 710. When the user rotates the adjusting knob 706, the locking mechanism is activated by the thumb and... The index finger pinches the adjustment knob 706 to rotate it, while the middle and ring fingers grip the pull column 709 and move it backward, causing the fixing block 710 to disengage from the outside of the fixing gear 708. This releases the fixation on the rotating shaft 705, allowing it to rotate. After adjusting the position of the electrooculogram reference electrode 8, the pull column 709 is released. Under the compression of the first spring 711, the fixing block 710 is pushed to fix the outside of the fixing gear 708, thus preventing the rotation of the rotating shaft 705 from affecting the operation of the electrooculogram reference electrode 8 and ensuring the stability of the sleep monitoring process.

[0041] In this embodiment, a power supply 101 is fixedly installed inside the eye mask body 1 and on the left side of the main circuit board 5. A control switch 102 and a charging port 103 are fixedly installed on the top of the eye mask body 1. A rubber sealing cover is provided on the outside of the charging port 103. The sleep aid headphones 4, EEG electrodes 6, EEG reference electrodes 8, power supply 101, control switch 102, and charging port 103 are all electrically connected to the main circuit board 5, charging the power supply 101 through the charging port 103. When the charging port 103 is not in use, its outside is protected by a rubber sealing cover. When monitoring the user's sleep, the eye mask body 1 is first worn over the eyes, and then... After the position of the electrooculogram (EOG) reference electrode 8 is adjusted, the control switch 102 is turned on to reduce or eliminate external noise interference using the sleep aid headphones 4, especially in noisy environments. By playing specific sounds, such as white noise or soft music, the sleep aid headphones 4 help relieve stress on the nervous system and soothe emotions, thereby helping users fall asleep more easily. At the same time, the inner side of the sleep aid headphones 4 is made of soft and skin-friendly material, such as liquid silicone, so it will not affect the health of the ear canal even after wearing it for a long time. After helping users fall asleep quickly, sleep monitoring is performed using the EEG electrode 6 and the EOG reference electrode 8, thereby greatly improving the efficiency of sleep monitoring.

[0042] In this embodiment, the inner side of the eye mask body 1 is provided with a head monitoring area 104 and an eye monitoring area 105, respectively. Flexible fabric is fixedly connected to the inner side of both the head monitoring area 104 and the eye monitoring area 105. A nose bridge groove 106 is provided at the bottom of the back of the eye mask body 1. After the user wears the eye mask body 1, the eye mask body 1 is supported on the bridge of the nose by the nose bridge groove 106. The head monitoring area 104 is in contact with the user's forehead, and the eye monitoring area 105 is in contact with the user's eyes. Since the inner side of both the head monitoring area 104 and the eye monitoring area 105 is fixedly connected with flexible fabric, the EEG electrode 6 can be as close as possible to the user's forehead. At the same time, when the position of the EEG reference electrode 8 is adjusted, the user can also sense the movement of the EEG reference electrode 8, so as to correctly adjust the EEG reference electrode 8 to the monitoring position of the user's eyes. This improves the wearing comfort of the eye mask body 1 while ensuring the monitoring accuracy of sleep monitoring.

[0043] In this embodiment, the bottom ends of both sets of adjustment arms 2 are rotatably connected to the connecting frame 3 through adjustment sleeves 201. The inner side of the adjustment sleeves 201 is provided with adjustment grooves that are adapted to the adjustment arms 2. The ends of both sets of adjustment arms 2 located inside the adjustment grooves are fixedly connected to limit blocks 202. Before the user wears the eye mask body 1, the adjustment sleeves 201 are pulled back according to the user's head circumference. The position of the sleep aid headphones 4 is adjusted by controlling the length of the adjustment arms 2 extending from the adjustment sleeves 201, so that the sleep aid headphones 4 can be adjusted to the ears according to different users' head circumferences. Thus, when wearing the eye mask body 1, the sleep aid headphones 4 cover the ears and fix the eye mask body 1 to the user's eyes.

[0044] In this embodiment, wiring holes 301 are provided on the inner side of both sets of connecting frames 3. Both ends of the inner side of the two sets of connecting frames 3 are rotatably connected to the sleep aid headphones 4 through mounting pins 302. The hidden wiring holes 301 are used to connect the sleep aid headphones 4, which makes the sleep aid headphones 4 more aesthetically pleasing while being used normally. At the same time, the sleep aid headphones 4 can swing inside the connecting frames 3 when worn, so that it can be adjusted according to the different head shapes of the users, making the sleep aid headphones 4 fit more closely to the outside of the user's ear and further improving the wearing comfort.

[0045] In this embodiment, a threaded post 303 is internally threaded onto the mounting pin 302. A second spring 304 is fixedly connected to one end of the threaded post 303 located inside the mounting pin 302. A pressing block 305 is fixedly connected to one end of the second spring 304 located inside the mounting pin 302. A retaining ball 306 is movably mounted inside the mounting pin 302 and outside the pressing block 305. Both the connecting frame 3 and the sleep aid earphone 4 are rotatably connected to the mounting pin 302. A retaining groove 307, adapted to the retaining ball 306, is provided inside the sleep aid earphone 4. The sleep aid earphone 4 is movably mounted inside the connecting frame 3 via the mounting pin 302. During installation, the mounting pin 302 is inserted into the connecting frame 3. After the corresponding holes of the connecting frame 3 and the sleep aid earphone 4 are aligned, the threaded column 303 is rotated to move the pressing block 305 towards the inside of the mounting pin 302 until the retaining ball 306 is squeezed out from the inside of the mounting pin 302. This causes the retaining ball 306 to be inserted into the retaining groove 307 inside the sleep aid earphone 4, thus installing the sleep aid earphone 4 inside the connecting frame 3. After installation, the sleep aid earphone 4 can also be adjusted by swinging inside the connecting frame 3, making the sleep aid earphone 4 fit the outside of the user's ear better. At the same time, rotating the threaded column 303 towards the outside of the mounting pin 302 causes the retaining ball 306 to retract into the inside of the mounting pin 302, facilitating quick disassembly and maintenance of the sleep aid earphone 4.

[0046] Implementation Plan: Before the user performs sleep monitoring, the adjustment sleeve 201 is pulled back according to the user's head circumference. The position of the sleep aid headphones 4 is adjusted by controlling the extension of the adjustment arm 2 from the adjustment sleeve 201, so that the sleep aid headphones 4 can be adjusted to fit the ears of different users. When wearing the eye mask body 1, the sleep aid headphones 4 cover the ears and fix the eye mask body 1 to the user's eyes. After the user wears the eye mask body 1, the head monitoring area 104 is in contact with the user's forehead, and the eye monitoring area 105 is in contact with the user's eyes. Since the inner sides of the head monitoring area 104 and the eye monitoring area 105 are fixedly connected with flexible... The fabric allows the EEG electrodes 6 to be as close as possible to the user's forehead. The spacing of the EEG reference electrodes 8 is then adjusted according to the user's eye distance. This is achieved by rotating the shaft 705 via the adjustment knob 706 on the outside of the eye mask body 1. The shaft 705 drives the bidirectional threaded rod 701 on the inner side of the spacing adjustment frame 7 to rotate. With the connection of the connecting sleeve 704 and the sliding rod 702, the rotation of the bidirectional threaded rod 701 synchronously moves the two sets of moving seats 703 relative to each other. The EEG reference electrodes 8 on the outside of the moving seats 703 are positioned at the eye level. Adjustment stops once the user senses that the EEG reference electrodes 8 have moved to the corresponding monitoring position at the eye, allowing different users to fall asleep. During monitoring, adjustments can be made accordingly. After adjustment, the rotating shaft 705 is fixed to prevent its rotation from affecting the position of the electrooculogram (EOG) reference electrode 8. After adjusting the position of the EOG reference electrode 8, the control switch 102 is turned on to reduce or eliminate external noise interference using the sleep aid headphones 4, especially in noisy environments. By playing specific sounds, such as white noise or soft music, the sleep aid headphones 4 help relieve stress on the nervous system and soothe emotions, thus helping users fall asleep more easily. The inner side of the sleep aid headphones 4 is made of soft, skin-friendly material, such as liquid silicone, so prolonged wear will not affect ear canal health. After helping the user fall asleep quickly, sleep monitoring is performed using EEG electrodes 6 and EEG reference electrodes 8. When the sleep aid headphones 4 are installed on the inside of the connecting frame 3 via the mounting pin 302, they are not only easy to disassemble and repair, but also can swing inside the connecting frame 3 when worn, allowing them to be adjusted according to different head shapes. This makes the sleep aid headphones 4 fit the outside of the user's ear more closely, further improving wearing comfort. The entire operation process is simple and convenient. Compared with existing sleep monitoring eye masks based on combined EEG and EEG detection, this invention improves the overall applicability and monitoring efficiency of sleep monitoring eye masks based on combined EEG and EEG detection through its design.
