Preferably: described conductive liquid storage lid passes through interference fit with electrode button I.
Preferably: described conductive liquid storage lid is threaded connection with electrode button I.
Preferably: described stopper is provided with Handheld Division.
Preferably: described adapter is db connector or splicing ear.
The beneficial effects of the utility model are: this utility model is by fixed electrode in electrode clip, and the conductive liquid storage of installing above of electrode button I is covered, and resin cotton is installed below.Conductive liquid storage lid the inside is placed with the conductive liquid of slow releasing agent, works conductive liquid and the effect slowly discharging of storing.There is following effect:
1, the use of spacetabs type conductive liquid, makes doctor not need to add conductive liquid, has alleviated doctor's work load, has reduced again the chance of artificial disturbance electroencephalogram waveform.
2, easily clean, water miscible conductive liquid is very easy to clean, and basic noresidue, can corrosion electrode.
3, resin cotton has certain elasticity and very soft, patient's comfortableness while having increased EEG (electrocardiogram) examination.
4, after patient checks out, noresidue on scalp and hair, it is dry, clean that hair easily recovers, and do not need hair washing.
5, the resin cotton below over cap, has good water absorption, water-retaining property, prevents that conductive liquid from trickling everywhere.Resin cotton flexibility is good.When examiner wears elastic cap, there is good comfortableness.
