Description

Technical Field

[0001] This utility model relates to the technical field of near-infrared detection technology, and in particular to a novel multifunctional photoelectric cap. Background Technology

[0002] As is well known, an optical cap is a device typically used in medical or scientific research fields. Multiple sets of optical electrodes inside the cap come into contact with the wearer's scalp. It utilizes the principle that near-infrared light penetrates the scalp and skull to reach and be absorbed by the brain tissue, measuring changes in the concentration of oxyhemoglobin and deoxyhemoglobin in the cerebral bloodstream. This method is commonly used to monitor the functional activity of the cerebral cortex, and it has particularly wide applications in cognitive science.

[0003] Traditional photoelectric caps have several shortcomings. First, they are not well-suited for adapting to different head circumferences, failing to meet the wearing needs of different individuals. This can lead to instability or discomfort, thus affecting the accuracy and reliability of signal acquisition. Second, traditional photoelectric caps lack clear and specific positioning markers, making it difficult to accurately place the electrodes in the required positions during experiments, thus hindering the precise acquisition of signals from specific brain regions. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a new type of multifunctional photoelectric cap that is comfortable and stable to wear and has accurate and reliable positioning.

[0005] This utility model discloses a novel multifunctional photoelectric cap, including a cap body, which is designed as a head-wrapping structure. The cap body is made of PU material, and the outer wall of the cap body is provided with a wearing positioning mark, which includes a Cz point and a T3 point. The Cz point is located at the center of the top of the cap body, and the T3 point is located on the side of the cap body. It is used to collect EEG signals from the left temporal lobe region of the brain. An auxiliary line is provided connecting the Cz point and the T3 point.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] like Figure 1-2 As shown, this utility model discloses a novel multifunctional photoelectric cap, including a cap body. The cap body is designed as a head-wrapping structure and is made of PU material. The outer wall of the cap body has wearing positioning markers, including a Cz point and a T3 point. The Cz point is located at the center of the top of the cap body, and the T3 point is located on the side of the cap body. These markers are used to collect electroencephalogram (EEG) signals from the left temporal lobe region of the brain. An auxiliary line connects the Cz point and the T3 point.

[0020] The CZ point is the name of an electrode location in the international 10-20 system of electroencephalography (EEG) electrode placement. This system is a standardized electrode placement method, with the CZ typically located in the central top of the head. It plays an important reference role in EEG signal acquisition and analysis.

[0021] T3 is also an electrode location in the international 10-20 system. T3 represents the left mid-left electrode location, primarily used to acquire EEG signals from the left temporal lobe of the brain. The temporal lobe plays a crucial role in auditory processing, language comprehension, and memory.

[0022] PU material has good elasticity, which can adapt to subjects with different head circumferences, ensuring a close fit between the cap and the head, and improving the accuracy of EEG signal acquisition. At the same time, PU material has a certain degree of flexibility and durability, and can be used multiple times without being easily damaged, reducing experimental costs;

[0023] The Cz point is located at the center of the top of the cap, and the T3 point is located on the side of the cap, with an auxiliary line between them. This allows for accurate placement of the electrodes when wearing the photoelectric cap, conforming to the international 10-20 system EEG electrode placement standard, thus ensuring accurate EEG signals from specific brain regions are acquired. This standardized positioning helps improve the reproducibility of experiments and the reliability of data.

[0024] As a preferred embodiment of the above, the front side of the cap is provided with multiple sets of openings, which cover the frontal lobe area of ​​the head. The number of openings is set to 15, specifically arranged in 3 rows and 5 columns.

[0025] The electrode fiber is connected to the scalp from an external device through the openings. The 15 openings allow the electrode fiber to cover the dorsolateral prefrontal cortex (DLPFC), ventrolateral prefrontal cortex (VLPFC), dorsolateral prefrontal cortex (DMPFC), and ventromedial prefrontal cortex (VMPFC) regions.

[0026] By creating openings in the prefrontal cortex, a channel was provided for the electrode fiber to access the scalp, allowing the electrode fiber to more accurately cover several important prefrontal cortical regions, such as the dorsolateral prefrontal cortex (DLPFC), ventrolateral prefrontal cortex (VLPFC), dorsomedial prefrontal cortex (DMPFC), and ventromedial prefrontal cortex (VMPFC). This allows for more comprehensive and precise acquisition of EEG signals from these brain regions, providing richer data for studying prefrontal cortex function. See details... Figure 2 ;

[0027] The number of openings is set to a 3-row, 5-column arrangement. This uniformly distributed opening method can make the distribution of electrode optical fibers more reasonable, improve the spatial resolution of signal acquisition, and reduce signal acquisition errors.

[0028] As a preferred embodiment of the above, the bottom two sides of the cap body are provided with straps, and the bottom of the two straps are provided with locking components;

[0029] The straps securely fasten the cap to the head, preventing displacement or loosening of the photoelectric cap during the experiment, thus ensuring continuous and stable contact between the electrodes and the scalp, and guaranteeing the continuity and stability of EEG signal acquisition.

[0030] As a preferred embodiment of the above, the locking component is specifically provided with a snap-on structure or a Velcro adhesive structure;

[0031] The device offers two optional fastening methods: snap-on or Velcro fastening, increasing its flexibility. Snap-on fastening provides a quick and secure hold, while Velcro fastening allows for finer adjustments to fit different head circumferences, further enhancing comfort and stability.

[0032] As a preferred embodiment of the above, a positioning reminder mark is provided at the front brim of the hat body; specifically, the reminder mark is set to "fixed above the brow bone";

[0033] This label provides operators with a clear reference for the wearing position, ensuring that the photoelectric cap can be accurately fixed in the same position each time it is worn, reducing signal acquisition errors caused by inconsistent wearing positions, and improving the accuracy and comparability of experimental data.

[0034] As a preferred embodiment of the above, the side of the cap is provided with a strap, and a hair-pulling device is removably installed in the strap;

[0035] For subjects with thick hair, the hair-parting device can separate the hair, allowing the electrode fiber to make better contact with the scalp, reducing interference from hair on signal acquisition and improving the quality of EEG signals. The cassette design facilitates the insertion, removal, and fixation of the hair-parting device, making it more convenient to use.

[0036] The overall beneficial effects of this novel multifunctional photoelectric cap are as follows:

[0037] I. Improve wearing comfort and adaptability

[0038] The cap is made of PU material, which has good elasticity and can adapt to subjects with different head circumferences, ensuring a comfortable and stable fit. Whether it is a child or an adult, individuals with different head shapes and circumferences can wear the photoelectric cap well, reducing the possibility of subject non-cooperation or experimental interruption due to discomfort.

[0039] The head-wrapping structure can better fit the head contour, reduce gaps, and improve wearing stability, thereby better maintaining contact between the photoelectric cap and the scalp during experiments, ensuring the accuracy and reliability of signal acquisition.

[0040] II. Precise positioning improves signal acquisition quality.

[0041] The outer wall of the cap is marked with positioning markers, including the Cz point, T3 point, and auxiliary lines between them. This conforms to internationally standardized electrode placement methods, ensuring accurate electrode placement in the desired locations and guaranteeing signal acquisition from specific brain regions. This is crucial for precise measurements in scientific research and medical fields, improving the accuracy and reproducibility of experimental data.

[0042] Multiple sets of openings on the anterior side cover the prefrontal cortex region, arranged in a 3-row, 5-column configuration. These openings allow for precise insertion of electrode fibers into corresponding areas of the scalp, covering several important prefrontal cortical regions, such as the dorsolateral, ventrolateral, dorsomedial, and ventromedial prefrontal cortex. This enables more comprehensive and accurate acquisition of signals from these brain regions, providing richer data for studying brain function.

[0043] III. Enhance ease of use and flexibility

[0044] The cap features straps and locking mechanisms on both sides of its bottom. These locking mechanisms can be either snap-on or Velcro, providing multiple securing methods to allow operators to choose the most suitable option based on the specific situation. Furthermore, the straps can be adjusted to accommodate different subject head circumferences, ensuring the photoelectric cap is securely fixed to the head and preventing displacement or loosening during experiments.

[0045] A positioning reminder mark is set at the front brim of the cap, providing operators with a clear reference for the wearing position. This ensures that the cap is accurately fixed in the same position each time it is worn, reducing signal acquisition errors caused by inconsistent wearing positions and improving the accuracy and comparability of experimental data.

[0046] The cap features a clip and a removable hair-pulling device on its side. For subjects with thick hair, the hair-pulling device can part the hair, allowing the electrode fiber to better contact the scalp, reducing interference from hair in signal acquisition and improving the quality of EEG signals. The clip design facilitates the insertion, removal, and fixation of the hair-pulling device, making it more convenient to use.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
