Description

Technical Field

[0001] This utility model relates to the field of electroencephalography (EEG) detection technology, specifically a disposable EEG electrode cap. Background Technology

[0002] Electroencephalography (EEG) is a technique that uses sophisticated instruments to amplify and record spontaneous bioelectrical potentials in the cerebral cortex from the scalp, producing an image. The collected brainwaves can be used not only for basic theoretical research in neuroscience but also for neurorehabilitation based on motor imagery in the field of stroke rehabilitation. Therefore, EEG technology has broad application value in medicine, neuroscience, psychology, and other fields.

[0003] However, existing EEG caps also have the following drawbacks:

[0004] 1. Traditional EEG caps are typically made of reusable materials, which can lead to electrode contamination after repeated use, increasing the risk of cross-infection. The reusable nature of traditional EEG caps and the incomplete cleaning process are the main factors contributing to this risk of cross-infection.

[0005] 2. Most existing EEG cap designs focus on functionality but neglect wearing comfort. They are too bulky, causing discomfort to users when worn for extended periods and even affecting the accuracy of signal acquisition.

[0006] 3. Existing EEG caps typically require several complex preparation steps before use. These include applying conductive gel, adjusting electrode positions, and calibrating signals. These steps not only require skilled technicians but can also be time-consuming, increasing the complexity of equipment use and patient waiting times. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a disposable brain electrode cap that reduces cross-infection while improving the convenience and comfort of wearing it.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a disposable brain electrode cap, comprising: a cap body made of disposable material; multiple brain electrode pads disposed on the cap body and detachably connected to the cap body; and a protective component disposed on the brain electrode pads, wherein conductive paste is applied to the detection surface of the brain electrode pads for protection.

[0009] Preferably, the protective component includes: a sealing cap disposed on the EEG pad, and forming a sealing groove on the detection surface of the EEG pad.

[0010] Preferably, the sealing cap is made of silicone.

[0011] Preferably, the protective component further includes: a sealing sticker disposed within the sealing groove and adhered to the conductive paste.

[0012] Preferably, the disposable material is made of non-woven fabric.

[0013] Preferably, the cap has multiple ventilation holes.

[0014] Preferably, a portable EEG device can be connected to the rear surface of the cap via Velcro.

[0015] Preferably, multiple EEG pads are arranged in a standard EEG array on the cap.

[0016] Preferably, the cap body has mounting holes, and the brain electrode pads are fixed to the mounting holes using a mounting structure.

[0017] The beneficial effects of this utility model are:

[0018] 1. The cap is made of disposable material, which on the one hand avoids the EEG cap being too bulky and improves the convenience and comfort of the user, and on the other hand, disposable use avoids the cross-infection caused by repeated use of the EEG cap;

[0019] 2. Applying conductive paste to the EEG electrode pads avoids the need for professional application and provides a sealed cap to ensure the cleanliness of the EEG electrode pads. Attached Figure Description

However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the embodiments without creative effort are all within the protection scope of this utility model.

[0026] Please see Figure 1-3 A disposable EEG cap includes: a cap body 4 made of disposable material; a plurality of EEG electrodes 1 disposed on the cap body 4 and detachably connected to the cap body 4; and a protective component disposed on the EEG electrodes 1, which applies conductive paste to the detection surface of the EEG electrodes 1 for protection.

[0027] The protective components include: a sealing cover 6, which is disposed on the brain electrode pad 1 and forms a sealing groove on the detection surface of the brain electrode pad 1.

[0028] The sealing cap 6 is made of silicone.

[0029] The protective components also include: a sealing sticker 7, which is disposed in the sealing groove and adhered to the conductive paste.

[0030] To use, simply remove the sealing cap 6 and peel off the sealing sticker 7 to begin signal acquisition.

[0031] To protect the EEG electrodes 1, this design provides each electrode 1 with a silicone sealing cap 6 and a sealing sticker 7 when not in use, ensuring the cleanliness and stable performance of the electrode 1. When in use, the user simply removes the sealing sticker 7, puts the electrode on, and can directly activate the EEG acquisition function, making operation convenient.

[0032] In this embodiment, the disposable material is made of non-woven fabric, which is lightweight, hygienic, and low-cost, making it very suitable for disposable use scenarios, especially for medical environments where cross-contamination must be avoided. In terms of overall structural design, the EEG cap achieves a high degree of fit to the head shape through an adjustable structure, ensuring stable and accurate positioning of each EEG electrode during signal acquisition.

[0033] In this embodiment, multiple ventilation holes 2 are opened on the cap body 4 to effectively improve breathability and make it suitable for long-term use.

This structure effectively simplifies the carrying and operation of the device, enhancing the user experience. The overall design is lightweight and versatile, embodying a combination of efficiency and practicality.

[0035] In this embodiment, multiple EEG pads 1 are arranged in a standard 10-20 EEG electrode array on the cap body 4 to ensure that the EEG pads 1 can fit tightly against the scalp, thereby improving the accuracy of signal acquisition.

[0036] The cap body 4 has mounting holes, and the brain electrode pads 1 are fixed to the mounting holes using a mounting structure.

[0037] The cap 4 also features a pre-installed interface for brain oxygen signal acquisition, allowing for simultaneous measurement of brain oxygen signals during EEG acquisition, thus enabling multi-parameter brain function monitoring. This design significantly expands the device's applicability, providing more possibilities for clinical diagnosis and scientific research analysis.

[0038] Ear clip electrode 3 is used to provide a reference signal for the EEG cap, helping to reduce artifacts caused by other body parts.
