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
The electroencephalogram (EEG) conducting resinl that the present invention relates in a kind of EEG(electrocardiogram) examination to reduce resistance between electrode and the scalp, conducts electricity very well, has no side effect.
Background technology
At present, the electrode mode of generally acknowledging in the EEG(electrocardiogram) examination is to use alcohol to do conducting medium, and many shortcomings are still arranged: cause that resistance is excessive, cause loose contact, cause the brain wave patterns distortion or cause disturbing artifact (being mainly the 50Hz ripple), make figure clear inadequately etc.
Summary of the invention
The purpose of this invention is to provide the electroencephalogram (EEG) conducting resinl that reduces resistance between electrode and the scalp in a kind of EEG(electrocardiogram) examination, conducts electricity very well, has no side effect.
The object of the invention is realized through following technical scheme.
A kind of electroencephalogram (EEG) conducting resinl is characterized in that: said electroencephalogram (EEG) conducting resinl comprises sodium chloride, glycerine, ethyl hydroxy benzoate, tragacanth, 95% ethanol and purified water; At cumulative volume is that the weight ratio of each component is in the electroencephalogram (EEG) conducting resinl of 100ml: sodium chloride 20%～25%, and glycerine 20%～26%, ethyl hydroxy benzoate 0.03%～0.05%, tragacanth 1.8%～2.2%, 95% ethanol 5%～10%, all the other are purified water.
The optimum weight ratio of each component of said sodium chloride, glycerine, ethyl hydroxy benzoate, tragacanth, 95% ethanol and purified water is: sodium chloride 20%, and glycerine 25.2%, ethyl hydroxy benzoate 0.03%%, tragacanth 2%, 95% ethanol 6%, all the other are purified water.
The manufacture method of said electroencephalogram (EEG) conducting resinl is: get purified water and add glycerine, ethyl hydroxy benzoate heating for dissolving, add the sodium chloride dissolving; In mortar, add ethanol, it is moistening in ethanol evenly to be sprinkled into tragacanth, and the limit edged grinds and adds above-mentioned mixed liquor, adds purified water at last to capacity, is ground to complete peptization.
Beneficial effect of the present invention is, can effectively reduce resistance (＜5k Ω, traditional sucrose＞20k Ω), and is without any side effects.
Embodiment
Describe in further detail in the face of the present invention down.
Electroencephalogram (EEG) conducting resinl of the present invention comprises sodium chloride, glycerine, ethyl hydroxy benzoate, tragacanth, 95% ethanol and purified water; At cumulative volume is that the weight ratio of each component is in the electroencephalogram (EEG) conducting resinl of 100ml: sodium chloride 20%～25%, and glycerine 20%～26%, ethyl hydroxy benzoate 0.03%～0.05%, tragacanth 1.8%～2.2%, 95% ethanol 5%～10%, all the other are purified water.The optimum weight ratio of each component of sodium chloride, glycerine, ethyl hydroxy benzoate, tragacanth, 95% ethanol and purified water is: sodium chloride 20%, and glycerine 25.2%, ethyl hydroxy benzoate 0.03%%, tragacanth 2%, 95% ethanol 6%, all the other are purified water.
Sodium chloride: make electrodes conduct and use.And the polymer substance tragacanth has electric charge, and its mucilage is met a large amount of electrolyte (sodium chloride) and can be precipitated; Metal ion (sodium chloride) also can generate deposition with water-soluble molecules material tragacanth simultaneously, influences the quality of the pharmaceutical preparations; The sodium chloride solution of preparation high concentration is difficult for dissolving, and sodium chloride concentration should be controlled.
Glycerine: rise wetting, preserve moisture, thickening, lubrication, be convenient to checked operation.Antisepsis is also arranged, and glycerol concentration can suitably strengthen.
Ethyl hydroxy benzoate: make anticorrisive agent, go bad because of mucilage is prone to microbiological contamination.
Tragacanth: preparation mucilage polymer substance commonly used, the viscosity of its consumption decision preparation.Therefore the viscosity of preparation is relevant with quality (manufacturer, different lot numbers etc.) with the consumption (content) of tragacanth, also according to operator's requirement.
95% ethanol: be used for moistening tragacanth, it is insoluble in alcohol to be convenient to tragacanth peptization (swelling) polymer substance tragacanth, and its aqueous solution is met the alcohol of more amount can separate out solute.Ethanol content can get final product by abundant moistening tragacanth, and is unsuitable too high.
Purified water is made solvent, makes tragacanth produce peptization (swelling).
The manufacture method of electroencephalogram (EEG) conducting resinl is: get purified water and add glycerine, ethyl hydroxy benzoate heating for dissolving, add the sodium chloride dissolving; In mortar, add ethanol, it is moistening in ethanol evenly to be sprinkled into tragacanth, and the limit edged grinds and adds above-mentioned mixed liquor, adds purified water at last to capacity, is ground to complete peptization.Beneficial effect of the present invention is, can effectively reduce resistance (＜5k Ω, traditional sucrose＞20k Ω), and is without any side effects.
