In addition, after the electroencephalogram monitoring is completed, the limitation on the second elastic pull rope 408 and the first elastic pull rope 403 of the elastic pull rope can be relieved by pulling the pull plate 504, so that the elastic pull rope can rebound to an initial state conveniently, subsequent wearing and use are facilitated, and the spring contraction rod 503 has an elastic contraction function and can change along with the movement of the extrusion locking block 502.
As an embodiment, the reset mechanism 6 comprises a piston cylinder 601 fixed on the first elastic plate 404 and the second elastic plate 405 respectively, and a piston rod 603 installed in the piston cylinder 601 in a sliding manner, wherein the outer end of the piston rod 603 is fixedly connected with a fixed ring 602, the fixed ring 602 can be respectively connected with a first limit pipe 406 and a second limit pipe 407 on the same side, the reset mechanism 6 further comprises an air bag 604 fixed on the outer surface of the first flexible sleeve 2, and the air outlet end of the piston cylinder 601 penetrates through the first flexible sleeve 2 and is communicated with the air bag 604.
In this embodiment, by setting the piston cylinder 601 and the piston rod 603, the piston rod 603 and the piston cylinder 601 can be compressed in the contraction process of the contraction mechanism 4, so that the gas in the piston cylinder 601 is extruded and transmitted into the air bag 604, and the air bag 604 is inflated, thereby improving the comfort level of the patient when the head is worn.
In addition, after the electroencephalogram monitoring work is finished and the locking of the contraction mechanism 4 is released, the contraction mechanism 4 can reset through the reset effect of the contraction mechanism 4, and gas can be extruded into the piston cylinder 601 again under the effect that the gas is discharged through the gas bag 604 when the contraction mechanism is reset, so that the piston rod 603 and the piston cylinder 601 are pushed to reset, and power is provided for the resetting process of the contraction mechanism 4.
When the head electroencephalogram monitoring is carried out on a patient, the whole device is placed on the head, at the moment, the pull rings 409 pull the second elastic pull ropes 408 and the plurality of elastic pull ropes first elastic pull ropes 403 to move in the side plates 1 simultaneously, and when the head electroencephalogram monitoring is carried out on the patient, the second elastic pull ropes 408 and the elastic pull ropes first elastic pull ropes 403 can be pressed and locked under the action of the pressing and locking blocks 502 and the spring shrinkage rods 503 in the locking mechanism 5, so that the second elastic pull ropes 408 and the elastic pull ropes first elastic pull ropes 403 cannot be reset, the pull rings 409 are continuously pulled until the elastic pull ropes first elastic pull ropes 403 drive the first elastic sleeve rods 402 to slide and shrink in the elastic sleeves 401 and the second elastic pull ropes 408 drive the first elastic plates 404 and the second elastic plates 405 to synchronously shrink, and the first flexible sleeves 2 and the second flexible sleeves 301 can shrink until the head-shaped elastic sleeves are shrunk to the size suitable for the patient.
And the second flexible sleeve 301 can be used for elastically extruding the detection electrode contact 304 through the telescopic spring 305 in the monitoring mechanism 3 when being contracted, so that the detection electrode contact 304 can be tightly contacted with the scalp of a patient when being contracted to a proper size, and the brain electricity monitoring work can be carried out on the patient through the data transmission line 306 and the information processing module 307.
After the electroencephalogram monitoring is completed, only the pulling plate 504 is pulled, the pulling plate 504 pulls the extrusion locking block 502 to retract, so that the locking of the second elastic pull rope 408 and the first elastic pull rope 403 of the elastic pull rope is released, and the quick resetting is performed through the elasticity of the inner parts of the retraction mechanism 4 and the power provided by the resetting mechanism 6.
