Description

Technical Field

[0001] This utility model relates to the field of rehabilitation therapy equipment technology, and more specifically to a children's EEG cap with adjustable electrode positions. Background Technology

[0002] An electroencephalogram (EEG) cap is a device used to collect electrical activity signals from the brain. It plays an important role in neuroscience research, medical diagnosis, and related rehabilitation treatments. An EEG cap typically consists of a cap body, electrodes, leads, and a signal acquisition module. The cap body is usually made of a flexible and soft material, designed to fit snugly to different head shapes to ensure good contact between the electrodes and the scalp. The cap body has multiple positions for placing the electrodes. The electrodes are one of the core components of the EEG cap, used to detect weak electrical signals on the scalp surface. Leads connect the electrodes to the signal acquisition device. The signal acquisition module is responsible for preliminary amplification and filtering of the weak EEG signals collected by the electrodes to improve signal quality, and then transmits the processed signals to a computer or other analysis equipment.

[0003] For EEG caps used by children, due to growth, the location of the EEG signal acquisition points on the head of children of different ages varies greatly. Therefore, the electrode positions for recording EEG signals need to be adjusted according to different users. However, the electrode positions of existing children's EEG cap products are basically fixed and cannot meet the needs of different users to adjust the electrode positions. Utility Model Content

[0004] To address the technical problems existing in current pediatric EEG caps, this invention proposes a pediatric EEG cap with adjustable electrode positions, comprising:

[0005] The main body of the EEG cap is designed to be flexible and elastic for wearing on the user's head, and an opening is provided at a predetermined position on the main body of the EEG cap.

[0006] An electrode support frame is detachably connected to the main body of the EEG cap. The electrode support frame includes a first support and a second support connected to the first support via a connecting structure. Both the first support and the second support are provided with electrode mounting seats, and the electrode mounting seats are provided with electrode mounting grooves.

[0007] Multiple electrodes are detachably connected to the electrode mounting slots of the electrode mounting base;

[0008] The connection structure is configured as a flexible, multi-directional deformation structure, allowing the user to change the position between the second support and the first support, and enabling the electrodes installed on the second support to move to openings at different positions on the EEG cap body.

[0009] Preferably, the first support is configured as a strip-shaped sheet structure and can be bent so that the first support can conform to the user's head contour.

[0010] Preferably, the second bracket is disposed on both sides of the first bracket via a connecting structure.

[0011] Preferably, the length direction of the connecting structure is perpendicular to the length direction of the first bracket or forms a predetermined angle with the length direction of the first bracket.

[0012] Preferably, the connecting structure is configured to include pleated units with alternating peaks and troughs, so that the connecting structure can stretch or bend along the length direction or bend along the thickness direction.

[0013] Preferably, the pleated unit is provided with a first wire guide groove, the depth of which is less than the thickness of the connecting structure.

[0014] Preferably, the electrode mounting base is provided with a second wire guide groove extending into the electrode mounting groove, and the second wire guide groove is located in the extending direction of the first wire guide groove.

[0015] Preferably, the side of the pleated unit with the first wire groove faces the EEG cap body.

[0016] Preferably, it also includes a signal acquisition module, which is connected to the first bracket.

[0017] Preferably, the signal acquisition module includes a housing and a cover, the housing being connected to the first bracket, and the cover being detachably connected to the housing.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] The novel electrode support frame includes a first support in a fixed position and a second support connected by a deformable connecting structure. The position of the second support relative to the first support can be changed, so the position of the sampling point can be adjusted to fit the head size of different children. At the same time, the electrode wiring is hidden under the electrode support frame, so that the EEG cap does not have messy wiring. Attached Figure Description

[0025] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0026] Combination Figure 1 and Figure 2 As shown, this utility model proposes a child EEG cap with adjustable electrode position, including an EEG cap body 10, an electrode support frame 20, and multiple electrodes 30.

[0027] Optionally, the EEG cap body 10 is worn on the user's head. In order to accommodate different head sizes, the EEG cap body 10 is designed to be flexible and elastic, for example, using nylon spandex mesh fabric, which has good elasticity, is breathable and comfortable for the user to wear.

[0028] Furthermore, the EEG cap body 10 has openings at predetermined locations. This allows for more sampling points to be provided for the electrodes 30, enabling adjustments to different sampling points to accommodate different children's head sizes.

[0029] In an optional embodiment, the electrode support frame 20 is detachably connected to the EEG cap body 10. The electrode support frame 20 includes a first support 21 and a second support 23 connected to the first support 21 via a connecting structure 22. Both the first support 21 and the second support 23 are provided with electrode mounting seats 24. The electrode mounting seats 24 are provided with electrode mounting grooves 25. Each electrode 30 is detachably connected to the electrode mounting groove 25 of the electrode mounting seat 24.

[0030] Understandably, the first support 21 is designed as a strip-shaped sheet structure that can be bent to conform to the user's head contour. Multiple electrode mounts 24 can be positioned at appropriate locations along the length of the first support 21 according to the needs of EEG acquisition.

[0031] The second support 23 can be connected to the first support 21 through the connecting structure 22. The second support 23 can be arranged more flexibly at different positions from the first support 21 to accommodate different head sizes.

[0032] Specifically, the connection structure 22 is configured as a flexible multi-directional deformation structure, which allows the user to change the position between the second support 23 and the first support 21, so that the electrode 30 installed on the second support 23 can be moved to the openings at different positions on the EEG cap body 10.

[0033] In this way, by adjusting the length of the connecting structure 22, the collection point of the second bracket 23 can be adapted to the head size of different children.

[0034] In an optional embodiment, the connecting structure 22 is configured to include pleated units with alternating peaks and troughs, enabling the connecting structure 22 to stretch or bend along its length or thickness.

[0035] Thus, by varying the wave structure, the position of the second support 23 can be changed by stretching or compressing, while this structure also has good flexibility.

[0036] In an optional embodiment, the second support 23 is disposed on both sides of the first support 21 via a connecting structure 22. This covers most of the area on both sides of the head, allowing the brain electrodes to be placed in the appropriate position.

[0037] Optionally, the length direction of the connecting structure 22 is perpendicular to the length direction of the first bracket 21 or forms a predetermined angle with the length direction of the first bracket 21.

[0038] Furthermore, the pleated unit is provided with a first wire guide groove, the depth of which is less than the thickness of the connecting structure 22. The electrode mounting base 24 is provided with a second wire guide groove extending to the electrode mounting groove 25, the second wire guide groove being located in the extending direction of the first wire guide groove.

[0039] In this way, the wiring connecting the electrodes can be hidden inside the folded unit, preventing the wiring from being exposed on the outside.

[0040] Preferably, the side of the pleated unit with the first wire channel faces the EEG cap body 10. In this way, the wiring is not visible from the outside, and the appearance does not appear cluttered.

[0041] Furthermore, it also includes a signal acquisition module 40, which is connected to the first bracket 21. The signal acquisition module 40 includes a housing 42 and a cover 41. The housing 42 is connected to the first bracket 21, and the cover 41 is detachably connected to the housing 42.

[0042] In an optional embodiment, the box 42 and the first bracket 21 adopt an integrated mold design, which can reduce assembly difficulty and production cost.

[0043] In conjunction with the above embodiments, the electrode support frame of this utility model includes a first support in a fixed position and a second support connected by a deformable connecting structure. The position of the second support relative to the first support can be changed, so the position of the sampling point can be adjusted to adapt to the head size of different children. At the same time, the electrode wiring is hidden under the electrode support frame, so that the EEG cap as a whole will not have messy wiring.

[0044] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
