Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electroencephalogram (EEG) simulation circuit monitoring devices, specifically a multi-channel EEG simulation circuit monitoring device. Background Technology
[0002] Electroencephalogram (EEG) signal monitoring and analysis is mainly used to study changes in brain function, sedation and analgesia status, changes in cognitive function, monitoring of anesthesia depth, and changes in anesthesia recovery. It usually converts complex EEG signals into a single index. Currently, commonly used EEG monitoring systems in clinical practice include the bispectral index (BIS), auditory evoked potential index (AEI), entropy index, etc. EEG signal monitoring and analysis is an important monitoring device in EEG analog circuits.
[0003] A search of Chinese patent (publication number: CN220757409U) reveals a brainwave signal analysis and monitoring device. This device includes: a brainwave signal analysis and monitoring instrument; a mounting base fixedly connected to the rear side wall of the instrument; fixing plates on opposite side walls of the mounting base; a push block, a movable rod, and a telescopic spring on the upper end of each fixing plate; two positioning seats located on either side above the mounting base; a return spring and a positioning block at one end of each positioning seat; and a connector connected to the mounting base. A positioning groove is formed on one side of the outer wall of the connector, and limit strips are fixedly connected to both symmetrical sides of the outer wall of the connector. This device connects the connecting wire to the brainwave signal analysis and monitoring instrument... When connecting the device, align the limiting strip with the limiting groove and position the positioning groove upwards. Simultaneously, apply pressure to the button plate, which in turn compresses the telescopic spring. The movable rod drives the push block to slide against the inner wall of the movable groove, further stretching the positioning seat and the reset spring. This causes the lower end of the positioning block to be positioned in the through hole. Finally, insert the connector into the bottom of the socket and release the pressure on the button plate. The reset spring then inserts the positioning block into the positioning groove, thus securing the connector and preventing the connecting wire from falling off during movement or use, improving practicality. However, this device uses a spring to fix the wire harness, and due to the characteristics of the spring, the wire harness is prone to instability. Therefore, a multi-channel EEG analog circuit monitoring device is needed to solve the above problem. Utility Model Content
