[0002] The electroencephalogram detector is a medical research instrument used in the fields of biology, electronics and communication technology, and computer science and technology.

[0003] The existing electroencephalogram detector is not provided with a wire harness device, and the detector may become entangled when in use, which may affect the normal use of the detector.

[0004] The existing patent (Announcement No.: CN219501018U) is an electrode positioning device for an electroencephalogram detector. A frame-type head cover with positioning holes arranged according to electrode sites is used in conjunction with an elastic column for clamping electrodes. The electrodes are pressed tightly against the scalp by adjusting the pressure of the elastic column on the patient's head, thereby preventing the electrodes from shifting or falling off. The elastic column is inserted into the frame-type head cover through the positioning hole, which is convenient for disassembly and replacement. The limit table on the elastic column guide sleeve enables the frame-type head cover to press the elastic column toward the patient's head. The elastic pressure of the spring on the electrode mounting seat is adjusted by changing the position of the adjusting rod, so that the electrodes clamped in the electrode mounting seat can be better pressed against the patient's scalp. The inspection and installation efficiency is high, and the electrodes are not easy to shift. The head cover has good positioning effect, high wearing comfort and good heat dissipation; the structure of the frame-type head cover is simple, reasonable, reliable and light, and it is convenient to accurately set the hole position of the positioning hole according to the electrode site; the rear strap is provided with a rear strap adjuster, which is convenient for wearing and adjusting according to the patient's head circumference; the head cover is provided with an elastic adjustment belt as a chin strap, which can better fix the head cover, and the head cover will not shift and fall off even if the patient shakes his head; the head cover body is made of medical polyethylene material to form a neutral hardness frame-type head cover, which has excellent mechanical strength and biocompatibility, good chemical stability, radiation resistance, good insulation, and is conducive to extending the overall service life; each strap of the head cover is wrapped with sweat-absorbent cotton, which is easy to disassemble and clean; positioning hole.

[0005] The technical problem existing in the technical solution of the utility model is that, since the detector has multiple groups of lead wires and the connected lead wires are of different lengths, these lead wires are easily entangled and twisted together during operation. Since the detector is not provided with a wire splitting device, more time is needed to sort out the lead wires during operation, separate the entangled and twisted lead wires, and then perform the lead connection operation of the EEG detector. In batch EEG examination work, this affects the operator's work efficiency during examination and increases the labor intensity of medical staff. Utility Model Content
