Description
Technical field
This utility model relates to field of medical device, relates to a kind of novel brain wave electrode specifically.
Background technology
Brain wave figure is at ad-hoc location, the brain cell electrical activity that the electrode placed by scalp surface is collected.The medicated cap that the fixed form of electrode adopts rubber strap or rubber tube to make at present mostly, wears uncomfortable, and because patient's head dummy is variant, each electrode is stressed even not, often makes partial electrode loose contact, affects the measurement of the signal of telecommunication.Simultaneously when measuring, need to hold gauze bundle being soaked with electrolyte under the electrodes, because Measuring Time is longer, the electrolyte therefore in gauze is easy to evaporation drying, make electrode and contact skin bad.
Utility model content
The technical problems to be solved in the utility model overcomes above-mentioned defect, provides a kind of comfortable wearing, measures novel brain wave electrode accurately.
For solving the problem, the technical scheme that this utility model adopts is:
Novel brain wave electrode, comprise housing, circular arc conductive plate and electrode contact, be provided with spring between described housing and conductive plate, insulating between described housing and conductive plate is arranged, insulate between described housing and electrode contact and arrange, between described electrode contact and housing, scalable is arranged.
Improve as one: be provided with electrolyte holding device below described conductive plate, be provided with skirtboard below described conductive plate, described skirtboard is arranged at outside electrolyte holding device and stops electrolyte to outflow.
Improve as one: described skirtboard is provided with through hole, described through hole is connected with conduit.Convenient supplementary electrolyte.
Improve as one: described electrolyte holding device is sponge ring or gauze circle.
Improve as one: described housing is connected with electrode contact screw thread pair, described electrode contact is provided with knob.
Owing to have employed technique scheme, this utility model comfortable wearing, well, Detection results is good for electrode and contact skin.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
