Detailed Description

The utility model is further described with reference to the following figures and detailed description.

For convenience of description, the circular headgear straps 11, the transverse headgear straps 12, and the longitudinal headgear straps 13 are collectively referred to as a headgear strap.

As shown in fig. 1 to 4: the electroencephalogram headgear comprises a headgear main body 1 and an electrode holder 2; the head cover main body 1 is of a hemispherical net structure, the head cover main body 1 comprises a circular head cover belt 11, three transverse head cover belts 12 and three longitudinal head cover belts 13, each head cover belt has elasticity, and an electrode fixer 2 is arranged at the intersection of the head cover belts; the electrode fixer 2 comprises a fixed seat 21 and a pressing sleeve 22, the fixed seat 21 comprises a bottom plate 211, an inner sleeve 212 and an outer sleeve 213, the inner sleeve 212 is connected to the bottom plate 211, the inner sleeve 212 is provided with an electrode mounting structure 214, a through cavity 215 is formed between the inner sleeve 212 and the outer sleeve 213, the periphery of the outer sleeve 213 is provided with four through holes 216, the pressing sleeve 22 is sleeved on the inner sleeve 212 and is in threaded connection with the inner sleeve 212, and the pressing sleeve 22 is inserted into the through cavity 215; the transverse headgear straps 12 and the longitudinal headgear straps 13 intersect, the transverse headgear straps 12 pass through the through cavity 215 and the two opposite through holes 216, the longitudinal headgear straps 13 pass through the through cavity 215 and the other two through holes 216, and the pressing sleeve 22 presses the transverse headgear straps 12 and the longitudinal headgear straps 13; the transverse headgear straps 12 and the circular headgear straps 11 are crossed, the circular headgear straps 11 pass through the passing cavity 215 and two opposite passing holes 216, the transverse headgear straps 12 are connected with the outer sleeve 213, and the pressing sleeve 22 presses the circular headgear straps 11; the longitudinal headgear straps 13 and the circular headgear straps 11 intersect, the circular headgear straps 11 pass through the passage cavity 215 and the two opposite passage holes 216, the longitudinal headgear straps 13 are connected with the outer sleeve 213, and the pressing sleeve 22 presses the circular headgear straps 11.

In use of the present invention, the electroencephalogram electrodes are connected to the electrode holder 2, and in particular to the electrode mounting structure 214. The electrode mounting structure 214 may be matched to an existing electrode, and the electrode mounting structure 214 is typically an electrode mounting hole.

The electrode holder 2 can move along the circular headgear straps 11, the lateral headgear straps 12, or the longitudinal headgear straps 13, so that the electrode holder 2 is adjustable in position. If the position of part of the electrodes is not satisfactory, the position of the electrode holder 2 is adjusted.

The electrode holder 2 cannot easily move along the respective headgear, otherwise the electrode holder 2 is unstable in position and easily moves. The electrode holder 2 is also not suitable for directly pressing the head strap and is not adjustable, which may cause difficulty in moving the electrode holder 2; when the electroencephalogram headgear is worn on the head of a detected person, the headgear straps are lengthened and reduced in diameter, so that the electrode holder 2 cannot be pressed down, the electrode holder 2 is easy to move, and the position of the electrode holder 2 is unstable.

For the reasons described above, the electrode holder 2 of the present invention compresses the headband by means of the compression sleeve 22. When the position of the electrode fixer 2 needs to be adjusted, the pressing sleeve 22 is loosened, the head sleeve belt is not pressed by the pressing sleeve 22, and the electrode fixer 2 is easy to move and convenient to adjust.

Further, the electrode holder 2 of the present invention preferably includes a pressing pad 23, the pressing pad 23 is located in the through cavity 215, and the pressing sleeve 22 presses the pressing pad 23 so that the pressing pad 23 presses the headgear strap. If the pressing sleeve 22 is a direct pressing headgear strap, the pressing sleeve 22 is rotated during the pressing operation, which tends to pull the headgear strap. Set up and compress tightly pad 23, then compress tightly sleeve 22 and push up and tightly compress tightly pad 23, compress tightly sleeve 22 and compress tightly pad 23 relatively rotatable, compress tightly the rotation of sleeve 22 and be difficult for causing the influence to the headgear area.

In order to more reliably wear the electroencephalogram headgear on the head of the subject, it is preferable that the electroencephalogram headgear include a securing strap 3, and both ends of the securing strap 3 are connected to the left and right sides of the headgear main body 1, respectively. The securing straps 3 may be sleeved under the chin of the subject, thereby making the electroencephalogram headset more reliably worn on the head of the subject.
