Electroencephalogram examination fixing device for children

Abstract

The invention discloses an electroencephalogram examination fixing device for children. The device structurally comprises electrode die sleeves, a switch button, an elastic jaw belt, ear clips, controllers, a head frame, side arms and a middle piece, wherein the elastic jaw belt is composed of a clamping base, a flange buckle, a pull belt, a torsion spring, a shaft rod and a rotating shaft. The invention discloses the electroencephalogram examination fixing device for children. The shaft rod movably penetrates through and is embedded in the right side of the bottom end of the head frame alongupper and lower ends of the shaft rod; then the clamping base pulls the flange buckle to be connected to the left side of the head frame to support and stabilize the pull belt, the pull belt is drivenby bending fingers downwards, so that the shaft rod accelerates along the thrust by virtue of the rotating shaft, simultaneously expands the distance of the torsion spring and is released after the head frame is attached to the brain of a child; and the torsion spring drives the shaft rod to shrink the pull belt under the action of no external force, so that the consolidation force of the torsionspring is improved, the head frame is prevented from slipping off and falling off, and the electroencephalogram examination can be continuously carried out.

Description

Technical field [0001] The invention is a fixing device for children's EEG examination, belonging to the technical field of medical EEG examination. Background technique [0002] EEG examination is a graph obtained by magnifying and recording the spontaneous biopotential of the brain from the scalp through an instrument. [0003] The prior art discloses an EEG examination fixing cap with application number CN201620220814.0, which includes a mesh elastic cap, and also includes a first fixing member for fixing the mesh elastic cap on the subject's head and The second fixing member, the first fixing member is an elastic fixing rope, the two ends of the elastic fixing rope are respectively symmetrically connected to the mesh elastic cap, the second fixing member is either a circle set on the edge of the mesh elastic cap Elastic fixing layer; or two hanging straps, one end of the two hanging straps is connected to the edge of the mesh elastic cap at the middle of the two ends of the el...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a fixing device for children's EEG examination, so as to solve the problem that the middle distance between the head frame of the equipment cannot be applied to children with different brain positions, and it is easy to sway as the child's body shakes and tilts under force. Falling off, causing interruption of EEG examination and damage to its equipment
