Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an anti-fall-off headgear for sleep electroencephalography (EEG) testing. Background Technology

[0002] As a core technology in the field of sleep medicine, sleep electroencephalography (EEG) is of great significance for in-depth exploration of sleep mechanisms, accurate assessment of sleep quality, and accurate diagnosis of various sleep disorders. By capturing the weak electrical signals generated by the brain during sleep, sleep EEG can clearly present the activity state of brain neurons, providing intuitive evidence for revealing physiological and pathological changes during sleep.

[0003] The headgear for sleep EEG testing mainly consists of a flexible cap, an electrode array laid out according to the international 10-20 system standard, and a signal transmission module. The flexible cap is made of skin-friendly and breathable material, closely conforming to the curve of the head for comfortable wear. The electrodes inside the cap can accurately collect scalp electrical signals. The signal transmission module amplifies and filters the collected weak EEG signals before transmitting them to the testing device via wired or wireless means. When in operation, the patient wears the headgear to sleep, ensuring full contact between the electrodes and the scalp to capture the electrical signals generated by the activity of brain neurons. After processing by the signal transmission module, the signals are transmitted in real time to the sleep monitoring system. The system converts the electrical signals into visualized EEG waveforms, providing data support for doctors to analyze sleep cycles and diagnose sleep disorders, thus helping to accurately assess sleep status.

[0004] In some current sleep EEG testing headgear, the electrodes on the back of the patient's head fall off during the sleep test, affecting the EEG results. To address this issue, a non-fall-off headgear for sleep EEG testing is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-fall-off headgear for sleep electroencephalography (EEG) testing, aiming to improve the problem of electrodes easily falling off during sleep testing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A head cover for sleep electroencephalography (EEG) testing that prevents slippage includes a head cover, an electrode block inside the head cover, a metal clip outside the electrode block, a transmission wire outside the metal clip, a rotating block rotatably connected to the top of the head cover, a rotating rod rotatably connected to the top of the rotating block, an adjusting rod slidably connected inside the rotating rod, a limit clamp rotatably connected to the top of the adjusting rod, a rotating screw threaded inside the rotating rod, a limit assembly slidably connected inside the head cover, an elastic band at the bottom of the head cover, and a slider buckle connected to the bottom of the head cover.

[0008] As a further description of the above technical solution:

[0009] The limiting component includes a sliding block, the outer side of which is slidably connected to the inside of the head sleeve. A first movable block is slidably connected inside the sliding block. A limiting block is provided outside the first movable block. A telescopic post is provided at the end of the first movable block away from the limiting block. A spring is sleeved on the outside of the telescopic post. An installation rod is slidably connected inside the sliding block. A pull rod is provided at the top of the first movable block. A fixed rod is rotatably connected outside the installation rod. A second movable block is provided outside the fixed rod.

[0010] As a further description of the above technical solution:

[0011] Another electrode block is slidably connected inside the headgear, and the side of the sliding block that is close to the second moving block is in contact with the outside of the other electrode block;

[0012] As a further description of the above technical solution:

[0013] The bottom end of the limiting clamp contacts the top end of the metal clamp, and the outer side of the other electrode block is slidably connected to the inside of the head sleeve.

[0014] As a further description of the above technical solution:

[0015] The top of the sliding block is provided with a groove, and the outside of the pull rod is slidably connected to the inside of the groove;

[0016] As a further description of the above technical solution:

[0017] The end of the telescopic column away from the moving block is fixedly connected to the inside of the sliding block, and the outside of the limiting block is slidably connected to the inside of the mounting rod;

[0018] As a further description of the above technical solution:

[0019] The adjusting rod has a limiting port on its outside, and the rotating screw is externally slidably connected to the inside of the limiting port;

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the position of the electrode can be adjusted. After the electrode is fixed, the rotating rod is rotated to make the limiting clamp rotate to the top of the metal clamp. The sliding adjusting rod is used to make the two contact. The rotating screw is rotated to fix the adjusting rod, limiting the position of the metal clamp and preventing it from falling off the electrode and affecting the detection results. In addition, some limiting components can be rotated by the rotating block to adjust the limiting direction, which facilitates the arrangement of the transmission wire and makes the detection operation more orderly.

[0024] 2. In this utility model, the sliding block and the second moving block move in opposite directions. At the same time, the pull rod is pulled to make the mounting rod slide into the sliding block. After the pull rod is released, the spring pushes the first moving block to make the limiting block slide into the mounting rod and fix its position. At this time, the two clamp the electrode block to prevent the electrode from shifting to the left or right due to the patient's movement, ensuring the accurate position of the electrode during the test and improving the test effect.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1 to 4As shown, this utility model discloses an anti-fall-off headgear for sleep electroencephalography (EEG) testing, comprising a headgear 1. The headgear 1 contains electrode blocks 4, whose layout and number strictly adhere to the international 10-20 system standard. The headgear 1 is precisely divided into 16 electrode installation areas, each clearly marked with lead identification. The surface of the electrode blocks 4 in contact with the scalp is made of a skin-friendly adhesive material, ensuring comfort while further enhancing the fit between the electrode blocks 4 and the scalp. This prevents the electrode blocks 4 from falling off or shifting even during complex movements such as turning over or head shaking. The headgear 1, as the main body of the headgear, effectively covers the patient's head and provides a mounting base for the electrode blocks 4 and other components. The electrode blocks 4 are used to collect brain signals. The key component for the electrical signal, electrode block 4, is firmly fixed inside the head cover 1 to ensure the stability of its relative position. A metal clip 11 is provided on the outside of electrode block 4, and a transmission wire 12 is provided on the outside of metal clip 11. Metal clip 11 is used to connect electrode block 4 and transmission wire 12, playing an important role in transmitting EEG signals. Transmission wire 12 is responsible for transmitting the EEG signals transmitted from metal clip 11 to the detection device for further analysis and processing. A rotating block 5 is rotatably connected to the top of head cover 1. The presence of rotating block 5 allows subsequent components to rotate flexibly. A rotating rod 6 is rotatably connected to the top of rotating block 5. Rotating rod 6 can rotate within a certain range through rotational connection with rotating block 5, making it convenient to adjust its position.

[0033] An adjusting rod 7 is slidably connected inside the rotating rod 6. The adjusting rod 7 can slide inside the rotating rod 6 to change the overall length to adapt to different needs. A limit clamp 8 is rotatably connected to the top of the adjusting rod 7. The limit clamp 8 is used to limit the metal clamp 11 to prevent it from falling off. A rotating screw 9 is threaded inside the rotating rod 6. The rotating screw 9 is threaded with the rotating rod 6 and can fix the adjusting rod 7 after it is adjusted to a suitable position. A limit assembly is slidably connected inside the head sleeve 1. The limit assembly is set to better fix the electrode block 4 and prevent it from shifting during the detection process. The bottom of the head sleeve 1 is provided with... There is an elastic band 2, and the bottom end of the head cover 1 is connected to a slider buckle 3. The slider buckle 3 works in conjunction with the elastic band 2. By adjusting the position of the elastic band 2 in the slider buckle 3, the tightness of the head cover can be precisely adjusted so that the head cover can be firmly fixed on the patient's head, neither too tight and causing discomfort, nor too loose and causing the head cover to fall off. The bottom end of the limiting clip 8 contacts the top end of the metal clip 11. The outer side of another electrode block 4 is slidably connected to the inside of the head cover 1. The outer side of the adjusting rod 7 has a limiting port 10. The outer side of the rotating screw 9 is slidably connected to the inside of the limiting port 10. The outer side of the elastic band 2 is slidably connected to the inside of the slider buckle 3.

[0034] Reference Figure 1 , Figure 3 and Figure 4The limiting component includes a sliding block 13, which is externally slidably connected to the inside of the head sleeve 1. The sliding block 13 can slide inside the head sleeve 1 to adjust its position to adapt to the positional requirements of different electrode blocks 4. The sliding block 13 is treated with a ceramic coating, which greatly improves its wear resistance and corrosion resistance. A moving block 14 is slidably connected inside the sliding block 13. The moving block 14 can slide inside the sliding block 13. A limiting block 15 is provided on the outside of the moving block 14. Under the action of the moving block 14, the limiting block 15 can restrict the mounting rod 16 to prevent it from moving arbitrarily. A telescopic post 18 is provided at the end of the moving block 14 away from the limiting block 15. The telescopic post 18 has telescopic properties. It can adapt to the movement of the moving block 14 to a certain extent. The telescopic column 18 is fitted with a spring 19. The spring 19 is made of a new type of composite memory alloy material, which has the characteristic of self-repairing micro-cracks. Even with long-term high-frequency use, it can maintain stable elastic deformation capability and effectively avoid the problem of limit failure caused by elastic fatigue. The spring 19 is outside the telescopic column 18 and can provide elastic force to push the moving block 14 to move. The sliding block 13 is slidably connected to the mounting rod 16. The mounting rod 16 slides inside the sliding block 13. The top of the moving block 14 is provided with a pull rod 17. The pull rod 17 makes it convenient for the operator to pull the moving block 14, thereby performing the sliding in and sliding out operation of the mounting rod 16.

[0035] The mounting rod 16 is externally rotatably connected to a fixed rod 21. The rotatable connection between the fixed rod 21 and the mounting rod 16 allows it to rotate within a certain range to adapt to different installation requirements. The fixed rod 21 is externally provided with a second movable block 20. The second movable block 20 cooperates with the sliding block 13 to clamp the electrode block 4 and prevent it from moving. Another electrode block 4 is slidably connected inside the head sleeve 1. The side of the sliding block 13 that is close to the second movable block 20 is in contact with the outside of the other electrode block 4. A groove is provided at the top of the sliding block 13. The pull rod 17 is externally slidably connected inside the groove. The end of the telescopic column 18 away from the first movable block 14 is fixedly connected inside the sliding block 13. The external side of the limiting block 15 is externally slidably connected inside the mounting rod 16. One end of the spring 19 is fixedly connected to the end of the first movable block 14 away from the limiting block 15. The other end of the spring 19 is fixedly connected inside the sliding block 13. The installation method of the spring 19 ensures the stable sliding of the first movable block 14.

[0036] Working principle: When medical staff need to perform an electroencephalogram (EEG) on a patient, the head cover 1 is placed over the patient's head and then secured in place by the elastic band 2 and the sliding buckle 3. When medical staff need to connect wires to the left and right sides of the patient, the electrode blocks 4 can be slid inside the head cover 1. After adjusting the position, the head cover 1 will compress and limit the position of the electrode blocks 4. Then, medical staff can move the sliding block 13 and the second sliding block 20 in opposite directions, causing the outer part of the mounting rod 16 to slide into the interior of the sliding block 13. Simultaneously, the operator needs to pull the lever 17 so that the outside of the mounting rod 16 can smoothly slide into the interior of the sliding block 13. Then, the control of the lever 17 is released, and the spring 19 will automatically push the moving block 14 to slide, thereby allowing the limiting block 15 to slide into the interior of the mounting rod 16 and restrict the position of the mounting rod 16. At this time, the sliding block 13 and the moving block 20 will restrict the position of the electrode block 4, preventing the position of the electrode block 4 from shifting left or right due to the patient's movement during the EEG detection process, thus ensuring the detection effect.

[0037] After the positions of the electrode blocks 4 are fixed, the rotating rod 6 can be rotated so that the bottom end of the limiting clip 8 rotates to the top end of the metal clip 11. Then, the adjusting rod 7 slides inside the rotating rod 6 so that the bottom end of the limiting clip 8 contacts the top end of the metal clip 11. Then, the rotating screw 9 is rotated so that the outside of the rotating screw 9 slides into the limiting port 10, thereby fixing the position of the adjusting rod 7 and restricting the position of the metal clip 11. This prevents the metal clip 11 from falling off the electrode blocks 4 when the patient is lying in bed, which would affect the EEG detection results. The limiting component outside the electrode blocks 4 fixed inside the head cover 1 can be rotated outside the head cover 1 by the rotating block 5 to adjust the direction of the restriction, which facilitates the arrangement of the transmission wires 12.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
