Half-head type head cover special for acquiring brain signals
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a half-head type headgear of special collection brain signal.
Background
The brain wave is formed by summing up the postsynaptic potentials generated synchronously by a large number of neurons when the brain is active, and is the overall reflection of the electrophysiological activity of brain nerve cells on the surface of the cerebral cortex or scalp, and the monitoring of the brain wave is widely applied to the existing clinical practice. The electroencephalogram measurement is that electrodes are placed on the head according to a certain position, a stable micro-electricity detection channel is formed through conductive adhesive, weak bioelectricity is accurately acquired, bioelectricity activity of the head of a human body is acquired, amplified and processed through electroencephalogram equipment such as an electroencephalograph, and waveforms of the bioelectricity activity are displayed and recorded. The electroencephalogram electrode cap body plays the roles of fixing the electrode and accurately positioning during electroencephalogram measurement, and the detection of the bioelectric signals of the head of a human body is realized by detecting weak currents of the head through the electrode. The electroencephalogram electrode caps used at present are mainly of a head sleeve type, are all of a uniform specification, cannot be adjusted, are poor in applicability, can be adapted to different people only by additionally manufacturing electrode caps of different specifications, are troublesome to use and are poor in effect.
Chinese patent No. CN201821169333.7 discloses an electroencephalogram cap capable of being quickly connected, which comprises a head cover and a plurality of lead connecting wires; the head sleeve is provided with a plurality of through holes, each through hole corresponds to a corresponding probe acquisition point position, and each through hole is fixedly provided with a conductive female head; one end of the conducting wire is a male head detachably fixed on a corresponding female head, the male head is electrically connected with the female head, the other end of the electrode wire is a connector used for connecting an external signal amplifying device, and the male head is electrically connected with the connector through the electrode wire. But this utility model mainly ensures the good contact of electrode and scalp through the elastic force of headgear, when probe acquisition point position increased on the headgear, can lead to headgear and incomplete laminating of head because of the head type reason of examinee, the condition of individual electrode contact failure appears. Secondly, the size of the head cover is fixed, and the electroencephalogram caps of various types need to be equipped according to the head circumference of different subjects, so that the detection cost is high.
