Quick conductive paste filling device based on electrode cap

Abstract

The present invention discloses a quick conductive paste filling device based on an electrode cap. The device comprises a plurality of flexible elastic belts and a plurality of suction injection ballsarranged on the elastic belts, and when the elastic belts are bent to have the same radian as the electrode cap, and the suction injection balls on the elastic belts are correspondingly inserted intoelectrode cavities in the electrode cap one by one. The plurality of the suction injection balls are arranged on the plurality of the flexible elastic belts, distribution of the suction injection balls on the whole filling device is consistent with distribution of electrodes on the electrode cap to be injected, as the elastic belts have certain elasticity, certain elastic belts can be bent to beattached to the electrode cap, suction ports of the plurality of the suction injection balls are inserted into the cavities of the electrode cap, by manually pressing the injection balls, conductive paste filling of the plurality of the electrode cavities is completed at one time, whole filling time can be shortened to 5 minutes, working efficiency is greatly improved, and data recording of brainelectrical activities is more accurate.

Description

technical field [0001] The invention relates to the technical field of measurement during reaction, in particular to a rapid filling device for conductive paste based on an electrode cap. Background technique [0002] EEG is one of the most commonly used scientific instruments in psychology and cognitive neuroscience. Its basic principle is to record the spontaneous and evoked electrical activities of nerve cells in the brain through multiple electrodes attached to the scalp. There are 32 electrodes, 64 electrodes, 128 electrodes, and 256 electrodes in existing EEG instruments. In terms of completeness of recording, 256 electrodes are more detailed and accurate than 128-electrode EEG recordings, and the spatial resolution is also higher. However, affected by some factors, the number of electrodes cannot be increased. Much, and not too much. In fact, the number of electrodes in the currently more general EEG is 64. [0003] Since the brain is an irregular "circle" and cove...

Problems solved by technology

Therefore, in the current situation, the preparation of EEG experiments takes a lot of time

When recording the spontaneous and evoked electrical activities of the nerve cells in the brain, it is necessary to cover the electrode cap on the head first, and then fill each hollow electrode with conductive paste, which will cause psychological problems to people if it takes too long. Adverse effects, causing irritability, discomfort and other experiences, thereby reducing the reliability and reproducibility of experiments
