Description

Technical Field

[0002] When brain nerves are active, weak electric field fluctuations are generated. When tens of thousands of nerves are active at the same time, the electric field will produce rhythmic fluctuations. These fluctuations can be measured from the scalp, namely brain waves.

[0003] Transcranial electrical stimulation (TES) is a non-invasive technology that uses weak current (0.5-2.0 mA) to regulate the activity of cerebral cortical nerve cells. Since the 1990s, people have conducted more extensive research on TES. With the continuous deepening of research on the central nervous system and neuroscience, people have a deeper understanding of TES, and at the same time, it has inspired the possibility of TES in the treatment of different neurological diseases, mental illnesses, motor skill learning, and brain cognitive ability enhancement.

[0055] Specifically, the first positioning structure 2121 and the second positioning structure 1111 are each provided with four, which are installed one by one. The four first positioning structures 2121 are provided at the four positions around the bottom of the second slot 212 to ensure the correct matching connection between the interference electrode component 20 and the wearable component 10, and to achieve a stable connection relationship. And by providing four positioning structures, the force can be evenly distributed around the connection point. This can reduce the excessive force on a single point.

[0056] Specifically, as another implementation of this embodiment, the first positioning structure 2121 is a positioning column, and the second positioning structure 1111 is a positioning slot, and the positioning column is inserted into the positioning slot so that the second magnetic suction member 21 is limited to the positioning slot.

[0069] like Fig.11 , Fig.12 and Fig.13 As shown, as another implementation of this embodiment, the clamping member 2163 is provided with a notch 21632, and the clamping member 2163 is provided with an elastic buckle 21631 at a position corresponding to the notch 21632, and the clamping seat 2164 is provided with an elastic convex strip 21642 adapted to the notch 21632, and the elastic convex strip 21642 is convexly provided on the clamping seat 2164, and the elastic convex strip 21642 can be elastically deformed in a direction away from the notch 21632 to expose the elastic plate 216311. When the clamping member 2163 is connected to the clamping seat 2164, the elastic convex strip 21642 can be well engaged with the notch 21632 to form a more secure connection. When the snap-on component 2163 needs to be removed, it is only necessary to apply a force on the elastic ridge 21642 in a direction away from the notch 21632 , and the elastic ridge 21642 will be elastically deformed, making it convenient for the user to remove the snap connection of the elastic buckle 21631 .

[0070] Specifically, the shell 22 disclosed in this embodiment is provided with a notch on the side facing the snap-fit ​​seat 2164 for accommodating the protruding portion of the elastic ridge 21642. The setting of the notch can provide a clear position and guide, making it easier to correctly match the elastic ridge 21642 with the shell 22 during the assembly process, thereby ensuring the stability of the connection between the snap-fit ​​seat 2164 and the shell 22.

[0071] Specifically, during the actual disassembly process, the user pries the elastic ridge 21642 away from the notch 21632 to expose the elastic plate 216311 of the elastic buckle 21631 provided on the notch 21632, and presses the elastic plate 216311 to make the locking block 216312 on its free end move away from the slot 21641 and disengage from the slot 21641. Then, this side of the snap-in component 2163 loosens from the snap-in seat 2164 so that the whole is no longer fixedly connected to the snap-in seat 2164, and the snap-in component 2163 can be easily removed.

[0072] In summary, the present application discloses that by setting a first magnetic component 11 on the wearable component 10 and a second magnetic component 21 on the interfering electrode component 20, the first magnetic component 11 and the second magnetic component 21 cooperate with each other by magnetic attraction, so that the assembly and disassembly of the wearable component 10 and the interfering electrode component 20 are convenient and quick, and the connection by magnetic attraction does not require too much effort, and the entire assembly and disassembly process will not cause wear, thereby maximizing the ease of installation and stability of the interfering electrode component 20.

[0073] In actual use, the interference electrode component 20 needs to directly contact the scalp, and sometimes needs to be covered with an electrode sleeve soaked in saline. The magnetically detachable design of the interference electrode component 20 is also convenient for cleaning and maintenance, allowing users to better maintain the hygiene of the interference electrode component 20. By disassembling the interference electrode component 20, users can clean the surface of the component more thoroughly, effectively reducing the possibility of bacterial growth, and further improving the safety and hygiene of use.
