Problems solved by technology

[0002] At present, the commonly accepted electrode method in EEG examination is to use alcohol as the conductive medium, which still has many disadvantages: excessive resistance, poor contact, distortion of EEG waveform or interference artifacts (mainly 50Hz waves), make the graphics not clear enough, etc.

Embodiment Construction

[0009] The present invention will be further described in detail below.

[0010] The EEG conductive glue of the present invention comprises sodium chloride, glycerin, ethylparaben, tragacanth gum, 95% ethanol and purified water; in the EEG conductive glue with a total volume of 100ml, the weight ratio of each component Contains: sodium chloride 20%-25%, glycerin 20%-26%, ethylparaben 0.03%-0.05%, tragacanth gum 1.8%-2.2%, 95% ethanol 5%-10%, and the rest is purified water. The optimal weight ratio of each component of sodium chloride, glycerin, ethylparaben, gum tragacanth, 95% ethanol and purified water is: sodium chloride 20%, glycerin 25.2%, ethylparaben 0.03%% , tragacanth gum 2%, 95% ethanol 6%, and the rest is purified water.

[0011] Sodium Chloride: used for electrode conduction. The polymer material tragacanth tape has a charge, and its mucilage agent can precipitate when it encounters a large amount of electrolyte (sodium chloride); at the same time, metal ions (s...

Abstract

The invention discloses an electroencephalogram conductive adhesive. The electroencephalogram conductive adhesive is characterized in that the electroencephalogram conductive adhesive comprises the following components in percentage by weight in 100ml total volume of the electroencephalogram conductive adhesive: 20%-25% of sodium chloride, 20%-26% of glycerin, 0.03%-0.05% of hydroxyphenyl ethyl ester, 1.8%-2.2% of tragacanth, 5%-10% of 95% ethanol and the balance of purified water. The optimal percentage by weight of each of the components, namely sodium chloride, glycerin, hydroxyphenyl ethyl ester, tragacanth, 95% ethanol and purified water is as follows: the sodium chloride accounts for 20%, the glycerin accounts for 25.2%, the hydroxyphenyl ethyl ester accounts for 0.03%, the tragacanth accounts for 2%, the 95% ethanol accounts for 6%, and the balance is the purified water. The electroencephalogram conductive adhesive disclosed by the invention has the beneficial effects of effectively reducing resistance (less than 5k omega and a traditional medium is more than 20k omega) and having no side effects.

Description

technical field [0001] The invention relates to an electroencephalogram conductive glue which reduces the resistance between electrodes and the scalp in the electroencephalogram examination, has good electrical conductivity and has no side effects. Background technique [0002] At present, the commonly accepted electrode method in EEG examination is to use alcohol as the conductive medium, which still has many disadvantages: excessive resistance, poor contact, distortion of EEG waveform or interference artifacts (mainly 50Hz waves), Make the graphics not clear enough, etc. Contents of the invention [0003] The purpose of the present invention is to provide a kind of electroencephalogram conductive glue that reduces the resistance between electrodes and the scalp, has good conductivity and has no side effects in electroencephalogram examination. [0004] The object of the present invention is achieved through the following technical solutions. [0005] A kind of electroe...
