Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, and in particular to an EEG cap based on a grid layout and a tightening device. Background Technology
[0002] Existing EEG caps generally employ fixed sizes or simple elastic designs, making it difficult to adapt to various head shapes and leading to poor electrode contact or reduced signal quality. Furthermore, traditional fixing methods (such as Velcro or fasteners) lack flexibility and cannot meet the comfort requirements for prolonged wear. Therefore, designing an EEG cap that is simple in structure, highly adaptable, and ensures stable electrode contact is of paramount importance. Utility Model Content

The cover body is provided with two layers of fabric, and a track is opened between the two layers of fabric along the transverse direction of the cover body; the elastic band is passed through the track and protrudes from the side of the cover body; the tightening device is connected to both ends of the elastic band.
[0004] Furthermore, the EEG cap based on the grid layout and tightening device also includes multiple brain electrodes, which are spaced apart on the cap.
[0005] The technical solution of this utility model, through the elastic band design with a grid layout, achieves adaptation to different head shapes. The tightening device can quickly adjust the overall tightness, improving wearing comfort. Electrode contact stability is enhanced, and the quality of EEG signals is significantly improved.

[0016] This invention proposes an EEG cap based on a grid layout and a tightening device, aiming to design an EEG cap with adjustable tightness based on a grid layout and a tightening device.
[0017] The specific structure of the EEG cap based on a grid layout and a tightening device proposed in this utility model will be described below in a specific embodiment:
[0018] In the technical solution of this embodiment, as shown in Figures 1 and 2, an EEG cap based on a grid layout and a tightening device includes: a covering body 10, an elastic band 20, and a tightening device 30. The covering body 10 has two layers of fabric inside, and a track is opened between the two fabrics along the transverse direction of the covering body 10; the elastic band 20 is inserted into the track and protrudes from the side of the covering body 10; the tightening device 30 is connected to both ends of the elastic band 20.
[0019] Furthermore, the EEG cap based on the grid layout and tightening device also includes multiple brain electrodes 40, which are spaced apart on the cover 10.
[0020] Specifically: The cover 10 is made of elastic material and has two layers of fabric inside. An elastic band 20 is arranged between the two layers of fabric, avoiding the electrodes, and the fit is improved by uniform pressure distribution. The elastic band 20 is guided through a specific area to ensure that it does not shift when tightened. The elastic band 20 is threaded in a track and exits from the cable outlet 11 on the side of the cover 10.
[0021] Above the ear: A tightening device is centrally located to adjust the tightness of the area at the top of the head.
[0022] Middle ear area: A tightening device is installed to adjust the tightness of the back and sides of the head.
[0023] The elastic band 20 uses a spring-loaded locking design, which locks the length of the elastic band 20 by pressing and releasing, simplifying the operation process. The end of the elastic band 20 is led out through a small hole or guide rail, and after tightening, the excess part is fixed in the side or internal storage slot.
[0024] Beneficial effects:
[0025] The elastic band 20 with a grid layout allows for adaptation to different head shapes.
[0026] The tightening devices in the supra- and mid-ear regions allow for quick adjustment of the overall tightness, improving wearing comfort. Enhanced electrode contact stability significantly improves the quality of EEG signals. Detailed implementation method:
[0028] The EEG cap is made of elastic fabric, consisting of inner and outer layers with a fabric insert in between, which forms the basis of a track. Multiple elastic bands 20 are then arranged along the track, avoiding the electrodes and improving fit through uniform pressure distribution. The elastic bands 20 are guided through specific areas to ensure they do not shift when tightened.
[0029] In use, the tension line is tightened or loosened by pulling the end of the elastic band 20, thereby adjusting the tightness of the EEG cap to make it fit the scalp better. The tension line is made of high-strength and durable fibers to ensure stability during long-term use.
[0030] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
