It is cup-shaped or circular electrode that electroencephalogram (EEG) recording electrode uses more at present, belongs to the non-intrusion type external electrode, will be full of on the cup-shaped of electrolyte electricity cream or the scalp surface that circular electrode is fixed on the patient with adhesive tape during use.Yet; Because the difference between the individual patients, part patient is prone to produce the head epidermis and infects, and because hair and skin oil and fat cause the loose contact between electrode and the skin easily; Non-intrusion type external electrode record electroencephalogram exists certain difficulty and limitation, influences patient disease diagnosis and treatment.
The utility model content
The purpose of this utility model is to provide a kind of intrusive mood EEG electrode; It is simple in structure, and is easy to use, through telescopic setting; Make things convenient for electrode needle directly to insert the human body head epidermis; The loose contact that exists when effectively avoiding the non-intrusion type electrode to use has improved the medical diagnosis on disease accuracy rate, thereby better treatment is provided.
For realizing above-mentioned purpose; This utility model provides a kind of intrusive mood EEG electrode; It comprises: electrode needle, the signal transmssion line that electrically connects with electrode needle and be placed in the sleeve on the electrode needle; This electrode needle has a pointed collection terminal, and its extension passes this sleeve, and this signal transmssion line and electrode needle electrically connect away from an end of collection terminal.
Said electrode needle is shape in the shape of a spiral.
Said electrode needle is shape linearly.
Said electrode needle collection terminal is 75 degree oblique angles.
Said sleeve extends the junction that a rib is placed in electrode needle and signal transmssion line away from an end of electrode needle collection terminal.
Convex with several ribs at interval on the said sleeve outer wall, the rib free end is provided with fillet.
Said electrode needle is processed by stainless steel silk.
Said sleeve is processed by PP or PVC.
Said signal transmssion line comprises the conductor that electrically connects with electrode needle and is coated on the insulator on the conductor that this insulator adopts PVC to process.
The beneficial effect of this utility model: the intrusive mood EEG electrode that this utility model provided; It is simple in structure; Easy to use, through telescopic setting, make things convenient for electrode needle directly to insert the human body head epidermis; The loose contact that exists when effectively avoiding the non-intrusion type electrode to use has effectively prevented that patient's head epidermis that the non-intrusion type electrode causes when using from infecting phenomenon simultaneously.
In order further to understand the characteristic and the technology contents of this utility model, see also following detailed description and accompanying drawing, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for this utility model is limited about this utility model.
Description of drawings
Below in conjunction with accompanying drawing, describe in detail through the specific embodiment this utility model, the technical scheme that makes this utility model and other beneficial effect is obvious.
In the accompanying drawing,
