Description

Technical Field

[0001] The utility model relates to the technical field of electroencephalogram (EEG) signal measuring equipment, in particular to a petal-shaped conductive silicone earplug for an EEG earphone. Background Art

[0002] Electroencephalography (EEG) is a non-invasive technique for recording the brain's electrical activity. It has been used to study brain function and disease since the early 20th century. Traditional EEG systems typically consist of multiple electrodes placed on the scalp, which capture electrical signals from the cerebral cortex and then process the signals. However, this system has some limitations, including complex electrode placement, inconvenience in use, and potential discomfort. In addition, electrodes on the scalp are easily affected by hair, sweat, and other factors, resulting in a decrease in signal quality.

[0003] To overcome these issues, ear canal-based EEG measurement technology has emerged in recent years. This technology uses electrodes placed in the ear canal to capture the brain's electrical activity. The skin inside the ear canal is relatively dry and free from interference from hair, providing a relatively stable signal environment. Furthermore, the use of electrodes inside the ear canal is more discreet and comfortable, making it suitable for long-term wear and daily EEG monitoring.

[0004] Most existing ear canal EEG devices use a single electrode design, that is, a single electrode is inserted into the ear canal for examination. This method obtains a single EEG signal and cannot provide multi-channel EEG signal measurement, which limits its use in complex EEG analysis and applications. Utility Model Content

[0021] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0022] To address the problem that most existing ear canal EEG devices use a single electrode design and cannot provide multi-channel EEG signal measurement, thus limiting their use in complex EEG analysis and applications, this application proposes a petal-shaped conductive silicone earplug that uses a multi-petal electrode design to achieve multi-channel EEG signal measurement, thereby improving signal acquisition accuracy and data comprehensiveness. The specific solution is as follows:

[0023] The utility model provides a petal-shaped conductive silicone earplug for an electroencephalogram headset, wherein the silicone earplug comprises an inner ring part and an outer ring part with a ring-shaped cross-section, the inner ring part is a cylindrical structure, and the outer ring part is an ellipsoidal structure; the inner ring part and the outer ring part form concentric circles, and there is a gap between the inner ring part and the outer ring part; one end of the inner ring part and one end of the outer ring part are integrally formed, and the outer ring part is sleeved on the outer surface of the inner ring; the silicone earplug adopts a two-layer structure, can adapt to ear canals of different sizes, and obtain electrical signals as close to the ear canal as possible.

[0024] The inner ring part and the outer ring part both include a silicone sheet 2 and an electrode sheet 1; there are multiple electrode sheets 1, and multiple electrode sheets 1 are equidistantly embedded between multiple silicone sheets 2 to form a structure with a ring cross-section, that is, each electrode sheet 1 forms a petal-like structure in the silicone earplug; each electrode sheet 1 is connected to an electronic module through a wire, and the electronic module is connected to an external monitoring device through a wireless transmission module.

[0025] There are multiple electrode sheets. Preferably, there are 2, 3, 4, 5, 6, 7 or 8 electrode sheets. The following is an example in which 2, 4, 6 or 8 electrode sheets are provided.

[0026] Implementation Case 1:

[0027] like Figure 1 As shown in the figure, in this embodiment, the silicone earplug is designed with two petal electrodes 1. This design can capture EEG signals from both sides of the ear canal and is suitable for basic EEG monitoring applications. Due to the small number of electrodes, the design and manufacturing costs are low, making it suitable for large-scale production and promotion.

[0028] The electrode sheet 1 is designed using highly conductive materials, including but not limited to gold or silver, to ensure stable and high-quality signal transmission. The earplugs are constructed from medical-grade silicone, which is soft and comfortable, allowing for extended wear without causing discomfort in the ear canal.

[0029] The two electrodes 1 are connected to an external electronic module via thin wires. This module performs preliminary signal processing, including amplification and filtering using an amplifier and filter unit. The processed signal is then transmitted via a wireless transmission module to an external monitoring device for further analysis and storage. This external monitoring device includes, but is not limited to, a computer, tablet, or mobile phone.

[0043] The eight electrodes are arranged so they capture EEG signals from more locations in the ear canal, improving signal acquisition accuracy. Each electrode is made of highly conductive and biocompatible materials to ensure signal quality and wearing comfort.

[0044] The eight-channel signals are transmitted via independent wires to the electronics module, which amplifies, filters, and pre-processes each channel's signal using an amplifier, filter, and processing unit. The processed signals are then sent to external monitoring equipment via a wireless transmission module, where users can analyze and review the data using dedicated software.
