Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an infrared electroencephalogram (EEG) electrode positioning device. Background Technology

[0002] In neuroscience research and clinical diagnosis, electroencephalography (EEG) is a crucial tool for monitoring brain electrical activity, and the accuracy of electrode localization directly impacts signal acquisition quality and the reliability of subsequent analysis results. Traditional electrode localization methods primarily rely on manual measurement and marking, which suffers from low accuracy, inefficiency, and susceptibility to human error, making it difficult to meet the demands of high-precision research. Although some existing devices have incorporated optical or electromagnetic localization technologies, they generally suffer from operational complexity, high equipment costs, and insufficient installation flexibility, limiting their widespread application in clinical and research settings.

[0003] To address this, existing technologies have developed EEG electrode positioning devices that utilize infrared or other positioning techniques to obtain the three-dimensional coordinates of the electrodes on the head with high accuracy. However, current EEG electrode positioning devices typically rely on drilling for installation, which not only damages the installation environment but also limits their application scenarios. For example, in medical institutions or laboratories, frequent changes in device location may damage walls, and drilling is not feasible in certain special scenarios (such as temporary monitoring environments). Furthermore, traditional supports are mostly rigid structures that only support adjustment in one direction, making it difficult to adapt to the multi-angle needs of different patient head shapes or complex surgical scenarios. Utility Model Content

[0004] To overcome at least one of the defects described in the prior art, this utility model provides an infrared electroencephalogram (EEG) electrode positioning device. This solves the problem of device installation disrupting the usage environment and addresses the need for multi-angle positioning.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] An infrared electroencephalogram (EEG) electrode positioning device includes: a fixing component, the fixing component including a fixing surface and an assembly surface, the fixing surface being detachably fixed to a wall, and the assembly surface being provided with a first ball joint; an infrared probe, the infrared probe being used to project a red dot onto a target electrode position; and an adjusting rod assembly, one end of the adjusting rod assembly being rotatably connected to the first ball joint of the fixing component, and the other end being movably connected to the infrared probe.

[0007] By adopting the above solution, the fastener can be detachably fixed to the wall without drilling, which will not damage the installation environment and solves the problems caused by traditional drilling fixing methods. One end of the adjusting rod assembly is rotatably connected to the first ball joint of the fastener. This ball joint connection method allows the adjusting rod assembly to be adjusted in multiple directions. Compared with the traditional rigid structure bracket that only supports adjustment in one direction, it can better adapt to the multi-angle needs of different patients' head shapes or complex surgical scenarios, and improve the adjustability and flexibility of the bracket.

[0008] Furthermore, an auxiliary component is provided between the fixing component and the wall. The auxiliary component includes an adhesive surface and a connecting surface. The adhesive surface is used to stick and fix the auxiliary component to the wall. The connecting surface is provided with a first connecting part, and the fixing surface is provided with a second connecting part. The first connecting part and the second connecting part are snap-fitted together.

[0009] By adopting the above solution, the stable fixing method of the auxiliary components provides a reliable support foundation for the entire positioning device. Stable fixing reduces positioning deviations caused by equipment shaking or displacement, indirectly ensuring the accuracy of the infrared probe's projected red dot positioning, and further mitigating the accuracy issues associated with traditional manual measurement and marking methods. The quick and convenient adhesive fixing method of the auxiliary components reduces the time and effort required for installing the positioning device.

[0010] Furthermore, of the first connecting part and the second connecting part, one is a concave groove and the other is a plug-in block that engages with the concave groove. The opening direction of the concave groove is opposite to the direction of gravity.

[0011] By adopting the above scheme, the snap-fit ​​method provides precise guidance for the installation of the positioning device. During installation, the operator only needs to align the plug block with the concave groove and then slowly push it along the groove to achieve accurate snap-fit. This precise positioning method avoids installation deviations that may occur in traditional installation methods, ensuring that the infrared probe can accurately project a red dot onto the target electrode position, thus improving the accuracy of electrode positioning. After the plug block is inserted into the concave groove, under the action of gravity, the plug block will be subjected to downward pressure, thereby tightly fitting against the inner wall of the concave groove. This tight fit makes the connection between the fixing component and the auxiliary component more robust and stable, providing reliable support for the entire positioning device and reducing positioning errors caused by equipment shaking or displacement.

[0012] Furthermore, the first connecting part and the second connecting part are magnetic components that can magnetically attract each other.

[0013] By employing the above method, when the two components approach a certain distance, the magnetic attraction automatically guides them into the correct position, achieving precise positioning. This helps the infrared probe project the red dot onto the target electrode more accurately, improving the accuracy of electrode positioning. Once the magnetic connection is established, it provides a relatively stable connection force. During equipment use, even with slight impacts or vibrations, the magnetic connection maintains a tight connection between the fixing and auxiliary components, reducing positioning deviations caused by loose connections and ensuring the stable operation of the positioning device.

[0014] Further, the adjusting rod assembly includes: a first rod body, one end of which is provided with a first ball joint groove for connecting with a first ball joint, and the other end of which is provided with a first shaft hole; a second rod body, one end of which is provided with a second shaft hole coaxial with the first shaft hole, and the other end of which is connected to the infrared probe; and a locking member, which passes through the first shaft hole and the second shaft hole.

[0015] By adopting the above solution, operation is simple and convenient, allowing staff to quickly adjust the position and angle of the infrared probe. The multi-directional adjustment function of the adjusting rod assembly provides the bracket with greater adjustability. In addition to the omnidirectional rotation adjustment of the first ball joint, the axial rotation adjustment of the two rod sections further increases the adjustment dimensions, enabling the infrared probe to more flexibly adapt to various complex electrode positioning requirements. By manipulating the locking mechanism, the adjusting rod assembly can be kept stable and fixed after being adjusted to the appropriate position, reducing positioning errors caused by bracket shaking or displacement and improving the stability of the bracket.

[0016] Furthermore, the fixing component includes an operating end and a fixing end. The operating end is provided with a plurality of axial grooves arranged at equal intervals along the circumference, and the fixing end is provided with an external thread along the circumference. The external thread is threadedly connected to the first shaft hole or the second shaft hole.

[0017] By adopting the above scheme, the axial groove can increase the torque, allowing for convenient and quick rotation of the locking component to achieve threaded connection or separation with the first or second shaft hole. Through the threaded connection, the locking component can tightly fix the first and second rods together, forming a stable integrated structure. When it is necessary to adjust the relative position of the two rods, simply loosen the locking component, adjust it to the appropriate position, and then retighten it. This connection method has advantages such as simple structure, reliable connection, and convenient disassembly.

[0018] Furthermore, one end of the infrared probe is provided with a second ball joint, and the other end of the second rod is provided with a second ball joint groove that connects to the second ball joint.

[0019] By adopting the above solution, the angle adjustment of the infrared probe becomes more flexible and precise, enabling it to meet various complex electrode positioning requirements.

[0020] Furthermore, the first ball joint groove is provided with a first expansion groove, which is used to increase the angle at which the first rod rotates toward the first expansion groove; the second ball joint groove is provided with a second expansion groove, which is used to increase the angle at which the infrared probe rotates toward the second expansion groove.

[0021] By adopting the above solution, the expansion slot provides the bracket with greater adjustment space, allowing for more flexible adjustment of the position and angle of the first rod and the infrared probe. In addition to the original axial rotation adjustment, the addition of the expansion slot further enhances the bracket's adjustability, enabling it to meet various complex installation environments and electrode positioning requirements.

[0022] Furthermore, the first expansion slot and the second expansion slot have the same slotting direction.

[0023] By adopting the above scheme, the consistent slotting direction helps to achieve a superimposed effect on the angle adjustment range of the first rod and the infrared probe. After the first rod rotates to its maximum angle in the first expansion slot, the infrared probe then continues to rotate in the same direction in the second expansion slot, thereby further expanding the angle adjustment range of the entire positioning device. This allows the positioning device to adapt to electrode position positioning requirements in more extreme situations, such as when the electrode position is located in a narrow corner of the equipment or in a position with a large angular deviation.

[0024] Furthermore, the infrared probe is equipped with a rechargeable power module.

[0025] By adopting the above solution, the built-in rechargeable power module eliminates the need for an external power cord for the infrared probe, completely freeing it from cable constraints and facilitating free movement and positioning in complex environments.

[0026] In summary, the infrared electroencephalogram (EEG) electrode localization device provided by this utility model has the following technical effects:

[0027] 1. The fasteners are fixed to the wall in a detachable manner without drilling. The installation and disassembly process is simple and quick, leaving no holes or marks and protecting the integrity of the installation environment. It is especially suitable for medical institutions, laboratories and other places where wall protection is required. At the same time, it solves the problem of not being able to drill holes in some outdoor emergency sites and temporary scientific research experimental sites.

[0028] 2. The detachable fixing method makes it easier to move the equipment between different scenarios, improves the efficiency and turnover rate of the equipment, reduces the cost of idle equipment, and can also reduce the additional maintenance costs caused by drilling installation.

[0029] 3. The adjusting rod assembly and the fixing component are connected by a ball joint, allowing for adjustment in multiple directions. This enables flexible adjustment of the infrared probe's position and angle based on the patient's head shape and electrode distribution, ensuring accurate projection of the red dot onto the target electrode. In complex surgical scenarios, such as neurosurgery, precise positioning of electrodes in different brain regions is required, and multiple probe adjustments may be necessary during the procedure. This invention's multi-angle adjustment function can quickly respond to these needs, improving surgical efficiency and safety.

[0030] 4. The ball joint connection makes the adjustment process smoother. Operators only need to turn the adjustment rod assembly to adjust the probe position without complicated operating steps and tools. Attached Figure Description

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0039] Example 1

[0040] See embodiments of this utility model. Figures 1-3 As shown, an infrared electroencephalogram (EEG) electrode positioning device is disclosed, including a fixing component 1, an infrared probe 2, and an adjusting rod assembly 3. The fixing component 1 includes a fixing surface 11 and a mounting surface 12. The fixing surface 11 is detachably connected to a wall, and the mounting surface 12 is provided with a first ball joint 121. One end of the adjusting rod assembly 3 is rotatably connected to the first ball joint 121 of the fixing component 1, and the other end is movably connected to the infrared probe 2. Optionally, the adjusting rod assembly 3 consists of a first rod body 31 and a second rod body 32. One end of the first rod body 31 is rotatably connected to the first ball joint 121 of the fixing component 1 through a first ball joint groove 311, and the other end is movably connected to the second rod body 32 through a locking component 33. The infrared probe 2 is connected to the second ball joint groove 322 of the second rod body 32 through the second ball joint 21, and is used to project a positioning red dot to the electrode position on the patient's head. With this design, the fixing component 1 can be detachably fixed to the wall without drilling, thus avoiding damage to the installation environment and solving the problems caused by traditional drilling fixing methods. One end of the adjusting rod assembly 3 is rotatably connected to the first ball joint 121 of the fixing component 1. This ball joint connection method allows the adjusting rod assembly 3 to be adjusted in multiple directions. Compared with the traditional rigid structure bracket that only supports adjustment in one direction, it can better adapt to the multi-angle needs of different patient head shapes or complex surgical scenarios, improving the adjustability and flexibility of the bracket.

[0041] In some specific embodiments, in the connection between the fastener 1 and the wall, optionally, the fixing surface 11 of the fastener 1 is made of high-adhesion silicone or vacuum adsorption material, which can be directly attached to the wall without drilling. Preferably, an auxiliary component 4 can be selected for assembly. Specifically, the auxiliary component 4 includes an adhesive surface 41 and a connecting surface 42. The adhesive surface 41 is fixed to the wall by double-sided tape or magnetic attraction. The connecting surface 42 is provided with a first connecting part 421, and the fixing surface 11 of the fastener 1 is provided with a second connecting part 111. The first connecting part 421 and the second connecting part 111 are snap-fitted together. In this embodiment 1, the first connecting part 421 is a plug-in block, and the second connecting part 111 is a concave groove. The plug-in block is snap-fitted and fixed to the concave groove. The opening direction of the concave groove is opposite to the direction of gravity. When the plug-in block is snapped into the concave groove, under the action of gravity, the plug-in block will be subjected to downward pressure, thereby tightly fitting against the inner wall of the concave groove. This tight fit makes the connection between the fixing part 1 and the auxiliary part 4 more secure and stable, providing reliable support for the entire positioning device and reducing positioning errors caused by equipment shaking or displacement. It should be noted that in other embodiments, the structures of the first connecting part 421 and the second connecting part 111 can be interchanged, and other letter-shaped snap-fit ​​structures can also be used for assembly and snap-fit.

[0042] In some embodiments, the adjusting rod assembly 3 is not limited to a specific structure, allowing it to rotate freely in the horizontal, vertical, and pitch directions. In this embodiment 1, the first rod body 31 has a first shaft hole 312 at its end, and the second rod body 32 has a second shaft hole 321 at its end. The locking member 33 passes through the two shaft holes, and the relative angle between the two rod bodies is fixed or adjusted by tightening or loosening the threads. Specifically, the locking member 33 is a bolt, including an operating end 331 and a fixed end 332. The operating end 331 is provided with a plurality of axial grooves 3311 evenly spaced along the circumference. The axial grooves 3311 can increase the torque, facilitating and quickly rotating the locking member 33 to achieve threaded connection or separation with the first shaft hole 312 or the second shaft hole 321. The fixed end 332 is provided with an external thread 3321 in its circumferential direction. The external thread 3321 is threadedly connected to the first shaft hole 312 or the second shaft hole 321, which can tightly fix the first rod 31 and the second rod 32 together to form a stable integral structure. When it is necessary to adjust the relative position of the two rods, simply loosen the locking member 33, adjust it to the appropriate position, and then tighten it again. This connection method has the advantages of simple structure, reliable connection, and convenient disassembly. The specific operation is as follows: loosen the locking member 33, adjust the relative angle between the first rod 31 and the second rod 32, tighten the locking member 33, and lock the first rod 31 and the second rod 32 through the thread to ensure that the position is stable after adjustment.

[0043] In some extreme environments, such as those requiring continuous turns, the adjustment range of the ball joint is limited, with the maximum rotation angle between each pair of directions typically being 90°. To address this range issue, a first expansion slot 3111 is provided in the first ball joint groove 311, and a second expansion slot 3221 is provided in the second ball joint groove 322. The opening directions of the first expansion slot 3111 and the second expansion slot 3221 are consistent, for example, both opening to the left. This configuration allows the first rod 31 and the infrared probe 2 to rotate an additional 15°-45° in the direction of the expansion slot, thereby expanding the adjustment range.

[0044] Due to the presence of the second ball joint 21 and the second ball joint groove 322, the infrared probe 2 can be angled within a range of 45°-135° in any two relative directions.

[0045] Preferably, in some embodiments, the infrared probe 2 is also equipped with a rechargeable power module. Specifically, it is a built-in or external lithium battery with a capacity of 5000mAh, which is charged through a Type-C interface and has a battery life of ≥8 hours, ensuring wireless operation. The built-in rechargeable power module eliminates the need for an external power cable for the infrared probe 2, completely freeing it from cable constraints and facilitating free movement and positioning in complex environments.

[0046] Example 2

[0047] This utility model, in Embodiment 2, improves upon Embodiment 1 by modifying the connection method between the fixing member 1 and the auxiliary member 4: the first connecting part 421 and the second connecting part 111 are magnetically attracted components. When they approach each other to a certain distance, the magnetic attraction automatically guides them into the correct position, thereby achieving precise positioning. This helps the infrared probe 2 to more accurately project the red dot onto the target electrode position, improving the accuracy of electrode positioning. Once the magnetic connection is established, it provides a relatively stable connection force. During equipment use, even with slight collisions or vibrations, the magnetic connection can maintain a tight connection between the fixing member 1 and the auxiliary member 4, reducing positioning deviations caused by loose connections and ensuring the stable operation of the positioning device. Specifically, a first magnetic block is embedded in the connecting surface 42 of the auxiliary member 4, and a second magnetic block is embedded in the mounting surface 12 of the fixing member 1. The two have opposite polarities and automatically attract and position themselves when close together.

[0048] The working principle of this utility model is as follows: The auxiliary component 4 is pasted to the wall, and the fixing component 1 is connected to the auxiliary component 4 by plugging or magnetic attraction. It should be noted that the pasting or magnetic fixation of the auxiliary component 4 can withstand a tensile force of ≥5kg to meet the clinical stability requirements. The infrared probe 2 is activated, and the spatial coordinate system of the device is calibrated by the reference patch or preset algorithm. After compensation by the error correction module, the electrode position error is ≤1mm, which meets the international EEG acquisition standard (IEC 60601-2-26). Then, the probe angle is adjusted by manually rotating the adjustment rod assembly 3 so that the infrared probe 2 covers the patient's head area. The adjustment range is expanded by using the first expansion slot 3111 and the second expansion slot 3221 to adapt to special angle requirements. The infrared probe 2 projects a red dot to the target electrode position. The operator attaches the electrode pad according to the red dot. The system generates an electrode coordinate report and a 3D model, which are wirelessly transmitted to the EEG analysis software.

[0049] In summary, the infrared electroencephalogram (EEG) electrode localization device provided by this utility model has the following technical effects:

[0050] 1. The fastener 1 is fixed to the wall in a detachable manner without drilling. The installation and disassembly process is simple and quick, leaving no holes or marks, thus protecting the integrity of the installation environment. It is especially suitable for places such as medical institutions and laboratories where wall protection is required. At the same time, it solves the problem of not being able to drill holes in some outdoor emergency sites and temporary scientific research experimental sites.

[0051] 2. The detachable fixing method makes it easier to move the equipment between different scenarios, improves the efficiency and turnover rate of the equipment, reduces the cost of idle equipment, and can also reduce the additional maintenance costs caused by drilling installation.

[0052] 3. The adjusting rod assembly 3 is connected to the fixing member 1 via a ball joint, allowing for adjustment in multiple directions. This enables flexible adjustment of the position and angle of the infrared probe 2 according to the patient's head shape and electrode distribution, ensuring accurate projection of the red dot onto the target electrode position. In complex surgical scenarios, such as neurosurgery, precise positioning of electrode positions in different brain regions is required, and multiple probe position adjustments may be necessary during the procedure. This invention's multi-angle adjustment function can quickly respond to these needs, improving surgical efficiency and safety.

[0053] 4. The ball joint connection makes the adjustment process smoother. The operator only needs to turn the adjustment rod assembly 3 to adjust the probe position, without complicated operation steps and tools.

[0054] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
