AI Technical Summary
During use, the connectors of existing multi-channel in vivo recording systems for acquiring EEG signals are prone to detachment, leading to signal interruption, affecting detection efficiency and data integrity, and even posing safety hazards in medical diagnosis.
The device employs a limiting and fixing post, an elastic component, and a multi-functional mechanism. The combination of the limiting and fixing post and the elastic component ensures a stable connection of the detection connector. The design of the rubber block and adhesive block ensures close contact between the device and the brain surface. Furthermore, the device's stability and the accuracy of signal acquisition are improved through an anti-interference layer and a heat dissipation and dehumidification component.
It effectively prevents the connector from falling off, improves the accuracy and safety of detection, enhances the stability of the device and the reliability of signal acquisition, and improves wearing comfort and signal acquisition quality.
