The detection is convenient, the sitting posture is comfortable, and it is convenient for the patient to detect for a long time. The touch screen 3 is set on the top surface of the backrest of the chair 1 which is easy to operate, and the operation is convenient.

[0022] As an improved specific implementation, the head-mounted detector 2 is also provided with a bracket 22, on which a rotating ball 25 is rotatably connected, and the rotating ball 25 is provided with a first threaded hole 251. The electrode rod 21 is also provided with a threaded shaft 213, and the threaded shaft 213 is engaged with the first threaded hole 251.

[0023] Through the above scheme, the rotating ball 25 is rotatably connected to the bracket 22, and the electrode rod 21 can rotate with the rotating ball 25. When wearing, the electrode rod 21 is adjusted to the best position by rotating the electrode rod 21, so that the top surface of the electrode rod 21 in contact with the patient's head is as close to the head as possible, avoiding the problem that the fixed electrode rod 21 is difficult to fully contact the patient's head. The threaded shaft 213 is engaged with the first threaded hole 251, so that the distance that the electrode rod 21 extends into the head-mounted detector 2 can be adjusted, which is convenient for adjusting the tightness of the contact between the electrode rod 21 and the patient's head.

[0024] As an improved specific implementation, a mounting seat 121 and a telescopic rod 122 are provided on the backrest of the seat 1, a telescopic cavity 123 is provided on the mounting seat 121, the telescopic rod 122 is slidingly connected to the telescopic cavity 123, and the telescopic rod 122 is rotatably connected to the head-mounted detector 2.

[0025] Through the above solution, the telescopic rod 122 is retractable relative to the mounting seat 121, and the telescopic rod 122 is rotatably connected to the head-mounted detector 2, which is convenient for adjusting the position of the head-mounted detector 2, and the head-mounted detector 2 is firmly and appropriately worn on the patient's head.

One end of the spring 214 is connected to the bottom surface of the output hole 211, and the other end of the spring 214 is connected to the opening and closing plug 213. A moving block 216 is provided on the opening and closing plug 213. The moving block 216 is slidably connected to the second slot hole 215 and extends out of the second slot hole 215. When the moving block 216 is slid to the upper end of the second slot hole 215, the opening and closing plug 213 opens the connecting hole 212; after the moving block 216 is released, the spring 214 pushes the opening and closing plug 213 to slide the moving block 216 to the lower end of the second slot hole 215, and the opening and closing plug 213 closes the connecting hole 212.

[0031] According to the above scheme, the moving block 216 is moved by hand, and the moving block 216 is slid to the upper end of the second slot 215, and the opening and closing plug 213 moves accordingly, and the plug body of the opening and closing plug 213 leaves the opening of the connecting hole 212, so that the connecting hole 212 is opened and communicated with the output hole 211, and the coupling agent adheres to the head through the output hole 211; after the moving block 216 is released, the spring 214 pushes the opening and closing plug 213, and the moving block 216 slides to the lower end of the second slot 215 with the opening and closing plug 213, and the opening and closing plug 213 closes the connecting hole 212, and the coupling agent is no longer delivered. The opening and closing plug 213 is used as a safety valve to prevent the electrode rod 21 from adhering to the head when the coupling agent is not used.
