Description

Technical Field

[0001] This invention relates to the field of electroencephalogram (EEG) monitoring technology, and more specifically to an EEG sleep monitoring device. Background Technology

[0002] Clinically, sleep monitoring typically requires an electroencephalogram (EEG) examination, which involves attaching electrodes to the skin at corresponding locations on the patient's head. These electrodes detect subtle changes in electrical activity in the brain, transmitting the signals to an instrument via electrodes and thus enabling the monitoring function. However, patients must wear these electrodes for up to 8 hours at a time, restricting their movement and making it difficult to adapt to different patients' sleep habits, thus affecting their sleep quality. Furthermore, head movements during sleep can easily cause the electrodes to fall off, affecting the sleep monitoring results. With each electrode fallout, medical staff must repeatedly check and reconnect them, increasing their workload.

[0003] In the prior art, Chinese patent CN215078396U discloses a special cap for sleep monitoring EEG, including a cap body that can be worn on the top of the head and a strap connected to it that can be tied to the chin. The cap body is provided with several detection holes for electrode pads to pass through, and the cap body is provided with a fixing structure around the detection holes to fix the electrode pads and electrode pad wires. Although it can prevent the electrode pads from falling off, ensure the patient's sleep quality, and reduce the impact on sleep monitoring results, the head position of the person is not always in one position when sleeping. When turning over, the outer wall of the helmet will inevitably scratch the bed. The hook and loop fasteners are Velcro, which are very easy to flip and detach when rubbing against the bed. The elastic soft sheet is also made of soft rubber material. After the hook and loop fasteners are removed, the electrode pads directly scratch the bed, which can also cause the elastic soft sheet to deform and fold, and the electrode pads will gradually tilt and slip off, thus affecting the final monitoring results. Summary of the Invention

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.

[0024] Example

[0025] like Figures 1 to 6 As shown, an EEG sleep monitoring device includes: a helmet 1, with grooves at both ends of the helmet 1. A fastening adjustment mechanism is installed at the end of the groove near the outer wall of the helmet 1. Fitting grooves are provided at both ends of the helmet 1's interior. Electrode pieces 2 are slidably connected to the inner side of the fitting grooves. A docking plate 3 is installed on one side of the electrode piece 2. A docking groove is provided on the outer side of the helmet 1, located on the side of the fitting groove. The docking groove is slidably connected to the docking plate 3. The electrode piece 2 and the docking plate 3 are engaged and connected by a splicing mechanism. The splicing mechanism includes a connecting compression component, a locking component, and an unlocking component. The connecting compression component is used for initial assembly of the electrode piece 2, and the locking component is used for... The device completely locks the position of the assembled electrode 2, and the unlocking component is used to unlock the position of the electrode 2. When in use, the electrode 2 can be initially assembled by connecting the compression component. The locking component completely locks the position of the assembled electrode 2, and the unlocking component unlocks the position of the electrode 2. The structure is simple and easy to operate. It prevents the outer wall of the helmet 1 from rubbing against the bed when turning over, which would cause the hook and loop fasteners to flip and detach, and the elastic soft sheet to deform and fold, causing the electrode 2 to tilt and slip off. This ensures the subsequent testing effect, is firmly fixed, and allows personnel to quickly pick up and put down the electrode 2 by pressing and pulling.

[0026] In this embodiment, the connecting compression assembly includes a locking block 4 installed at one end of the docking plate 3. A locking groove is formed inside the helmet 1 on one side of the docking groove, and the locking groove and locking block 4 are slidably connected. A placement groove 5 is formed inside the helmet 1 on one side of the locking groove. A limiting seat 6 is installed at one end of the inner side of the placement groove 5. A movable block 7 overlaps on one side of the limiting seat 6. First slopes are formed at the opposite ends of the movable block 7 and the locking block 4, and the two sets of first slopes fit together. A limiting groove is formed at the top of the limiting seat 6, and a limiting block 8 is slidably connected to the inner side of the limiting groove. One end of the limiting block 8 is fixedly connected to one side of the movable block 7. A first spring is installed between the limiting block 8 and the inner wall of the limiting groove. Spring 9 and movable block 7 have a compression groove on one side. A second spring is installed between the compression groove and the inner wall of the placement groove 5. A first rubber pad 10 is installed on one side of the docking plate 3. The first rubber pad 10 has a docking hole inside. The docking hole is slidably connected to the locking block 4. First, the electrode plate 2 is aligned with the fitting groove and inserted, and the docking plate 3 is also slid into the docking groove. The locking block 4 slides into the placement groove 5 through the locking groove. The first rubber pad 10 is pressed down and compressed. The locking block 4 and the first slope on movable block 7 are pressed and contacted with each other. The limiting block 8 is then driven to slide inside the limiting groove, which compresses and retracts the second spring. The first spring 9 is also compressed accordingly.

[0027] In this embodiment, the locking component includes a first positioning groove located inside the movable block 7 on the first slope, and a second positioning groove located inside the locking block 4 on the first slope opposite to the movable block 7. A positioning rod is rotatably connected to the inside of the first positioning groove, and a positioning plate 11 is sleeved on the outside of the positioning rod. A second slope that fits against the first slope on the locking block 4 is opened on one side of the positioning plate 11. A torsion spring 12 is installed between the positioning rod and the first positioning groove. Then, the operator needs to continue pressing down so that the first slope on the locking block 4 contacts the second slope on the positioning plate 11, forcing it to drive the torsion spring 12 to retract to the inside of the first positioning groove. After the locking block 4 is pressed down to a certain position, the positions of the second positioning groove and the first positioning groove correspond, and the positioning plate 11 inside the first positioning groove pops out to the inside of the second positioning groove. At this time, the docking plate 3 is released, the first rubber pad 10 rebounds a certain distance, and the positioning plate 11 abuts against the inner wall of the second positioning groove, completing the locking.

[0028] In this embodiment, the unlocking component includes an extension groove inside the helmet 1 located on one side of the placement groove 5. A buckle groove is formed inside the helmet 1 between the extension groove and the placement groove 5. A buckle rod 13 is installed on one side of the limiting block 8, and the buckle rod 13 is slidably connected to the buckle groove. A lever 14 is rotatably connected to one end of the buckle rod 13 extending into the extension groove. A sliding groove is formed on one side of the outer wall of the helmet 1 located in the extension groove. A sliding plate 15 is slidably connected to the inner side of the sliding groove and the extension groove. Connecting grooves extending into the inner side of the extension groove are formed on both sides of the inner wall of the sliding groove. Connecting blocks 16 that are slidably connected to the connecting grooves are installed at both ends of the sliding plate 15. A locking mechanism is formed on one side of the inner wall of the extension groove. The sliding plate 15 has a latch 17 installed at one end, which engages with the latch groove. Both ends of one side of the sliding plate 15 have latching slots. Furthermore, by engaging the latching slots, the latch 17 on the sliding plate 15 can be separated from the latch groove. Then, with the help of the connecting block 16 and the connecting groove, it can slide towards the inner wall of the sliding groove, exposing the lever 14. Then, by moving the lever 14, the lever 14 can work with the latching rod 13 and the limiting block 8 to move the movable block 7 actively, so that the positioning plate 11 moves away from the inner side of the second positioning groove. At this time, the first rubber pad 10 rebounds a certain distance. When the lever 14 is released, the positioning plate 11 will no longer be stuck in the second positioning groove, thus completing the separation.

[0029] In this embodiment, the binding adjustment mechanism includes a mounting base 18 installed at one end of the inner side of the groove. A take-up and release roller 19 is rotatably connected to one end of one side of the mounting base 18. A connecting rod is installed at one end of the mounting base 18, and a positioning plate 20 is installed at one end of the connecting rod. Multiple sets of positioning holes are arranged on one side of the positioning plate 20. A rotating shaft 21, rotatably connected to the positioning plate 20, is installed at one end of the take-up and release roller 19. A movable sleeve 22 is fitted onto the outer side of the rotating shaft 21 extending to the other side of the positioning plate 20. A positioning post 23, engaging with the positioning hole, is installed on one side of the protruding end of the movable sleeve 22. A binding rope 24 is fixedly connected to one side of the take-up and release roller 19. Synchronization grooves are provided inside the movable sleeve 22 on both sides of the rotating shaft 21. A positioning post 23, engaging with the positioning hole, is installed at both ends of the rotating shaft 21. The timing block 25 is slidably connected to the timing groove. A third spring is installed between one side of the timing block 25 and the inner wall of the timing groove. A pull ring is installed at one end of the movable sleeve 22. A support plate 27 is installed between the two sets of binding ropes 24. A second rubber pad 26 is embedded in one side of the support plate 27. Furthermore, by fastening the pull ring, the movable sleeve 22 is moved, causing the timing block 25 to compress the third spring. After the positioning post 23 is disengaged from the inner side of the positioning hole, the pull ring is twisted to drive the rotating shaft 21 and the take-up and release roller 19 to rotate. The binding rope 24 can be wound up or released when the take-up and release roller 19 rotates. After the second rubber pad 26 on the support plate 27 is completely in contact with the person's chin, the pull ring is slowly released so that the positioning post 23 is inserted into the corresponding positioning hole, thus fixing the length of the binding rope 24.

[0030] Implementation plan: Align electrode 2 with the mating groove and insert it, along with mating plate 3, which also slides into the mating groove. Locking block 4 slides into placement groove 5 through the locking groove. Continue pressing down to compress the first rubber pad 10. The first slope of locking block 4 and movable block 7 press against each other, causing limiting block 8 to slide within the limiting groove, compressing the second spring and compressing the first spring 9. Continue pressing down to make the first slope of locking block 4 contact the second slope of positioning plate 11, forcing it to drive torsion spring 12 back into the first positioning groove. After locking block 4 is pressed down to a certain position, the second positioning groove and the first positioning groove are aligned. Positioning plate 11 inside the first positioning groove pops out into the second positioning groove. At this point, release mating plate 3, and the first rubber pad 10 rebounds a distance. Positioning plate 11 abuts against the inner wall of the second positioning groove, completing the locking. Then, fasten the latching groove to drive the sliding plate 15. The buckle 17 separates from the buckle groove, and then, in conjunction with the connecting block 16 and the connecting groove, it can slide towards the inner wall of the sliding groove, exposing the lever 14. Then, by moving the lever 14, it can work with the buckle rod 13 and the limit block 8 to drive the movable block 7 to move actively, so that the positioning plate 11 moves away from the inner side of the second positioning groove. At this time, the first rubber pad 10 rebounds a certain distance. After releasing the lever 14, the positioning plate 11 will no longer be stuck in the second positioning groove, completing the separation. The pull ring is fastened to drive the movable sleeve 22 to move, so that the synchronizing block 25 squeezes the third spring to compress. After the positioning post 23 is disengaged from the inner side of the positioning hole, the pull ring is twisted to drive the rotating shaft 21 and the take-up and release roller 19 to rotate. The binding rope 24 can be wound up or released when the take-up and release roller 19 rotates. After the second rubber pad 26 on the support plate 27 is completely in contact with the person's chin, the pull ring is slowly released to make the positioning post 23 snap into the corresponding positioning hole, thus fixing the length of the binding rope 24.

[0031] This invention uses a connecting extrusion assembly to initially assemble the electrode pieces, a locking assembly to completely lock the assembled electrode pieces, and an unlocking assembly to release the lock on the electrode pieces. The structure is simple and easy to operate. It prevents the outer wall of the helmet from rubbing against the bed when turning over, which could cause the Velcro to flip and detach, the elastic film to deform and fold, or the electrode pieces to tilt and slip off. This ensures the subsequent testing results and allows personnel to quickly pick up and put away the electrode pieces.
