Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of electrode strap for visual function test.
Background technology
Visual evoked potential (VEP) is understood from retina to visual cortex, i.e., entire pathways for vision functional completeness inspection
It surveys.Images of left and right eyes is stimulated to record Evoked ptential P100 in visual cortex respectively by specific gridiron pattern inverted pattern.According to P100
Incubation period and wave amplitude analysis path damage the level before retina, optic chiasma or after optic chiasma, to the extent of damage, therapeutic effect
And objective evaluation is made in prognosis.
When carrying out visual evoked potential test, need multiple electrodes being fastened in head different location by fixed band
To obtain electrical potential information.When single channel, need respectively to place an electrode in the middle part of head forehead and hindbrain, due to being the position of centering
It sets, the relatively good determination in position of electrode, if but when multichannel, such as triple channel needs each side increasing in the middle part of hindbrain
Add an electrode, and needs to ensure that the distance from middle part to both sides is the 10% of head circumference；And when Five-channel, then it needs in hindbrain
The both sides up and down in portion respectively increase an electrode, it is also desirable to ensure that the distance from middle part to upper and lower both sides is the 10% of head circumference.Doctor
In practical operation, need to first pass through fixed band and carry out examination fixation, measure the physical length that fixed band uses, with head circumference length
Degree, then by the length of head circumference divided by 10, the deviation value of electrode is obtained, then electricity is made in the upper and lower and/or left and right sides of fixed band
Pole station location marker is finally completed electrode and is placed at mark, whole process operation is cumbersome, and the time is long, influences testing efficiency, increases doctor
Raw labor intensity.
It is therefore proposed that a kind of fixing device can quickly and accurately obtain electrode fixed position, to improving the work of doctor

Specific implementation mode
Hereinafter reference will be made to the drawings, and the preferred embodiment of the present invention is described in detail.It should be appreciated that preferred embodiment
Only for illustrating the present invention, the protection domain being not intended to be limiting of the invention.
As shown in Figure 1 to Figure 2, a kind of visual function provided by the invention tests electrode strap, including fixed band body 1,
The length scale 2 that can reflect its physical length is provided on fixed band body, the length scale of the present embodiment is to be arranged in fixation
To the unidirectional scale of the other end, unidirectional scale can be continuously arranged in the overall length of fixed band body, can also for one end of band
It is continuously to be arranged in a bit of length of fixed band body, but need to ensure is：It is trapped among on head when band body will be fixed
When, length value of the fixed band body actual participation around that part of head can be read, you can the actual length of head circumference is obtained,
Meanwhile for convenience of specifically illustrating the position of electrode, electrode position scale is set in the central region of fixed band body, when knowing
When the positional value of electrode, you can read the numerical value on electrode position scale, then place an electrode in this position, that is, complete
The positioning of electrode；In addition, according to the difference in channel, the scale that electrode position scale specifically includes is different, when for triple channel
When, electrode position scale is from the center of fixed band body overall length to left side and center to the two-way horizontal scale 3 on right side；When for
When Five-channel, electrode position scale further includes being erected from the center of the overall length of fixed band body to upper end and center to the two-way of lower end
Straight scale 4；When specific measurement, it will first fix in the middle part of the middle part of band and the hindbrain of gauger and be aligned, then will fix the both ends of band
Be adhesively fixed at forehead, when bonding, should by the initiating terminal of length scale upward, end downward, in order to read scale value,
The as length of head circumference, then by the length of head circumference divided by 10, obtain the positional value of electrode, if as shown in fig. 7, head circumference length is L,
Then the positional value of electrode is L/10, i.e. horizontal scale value and vertical scale value should be L/10.
More first selecting, the length scale of the present embodiment is to be arranged fixing with the continuous scale in a bit of length,
And its tag value is identical as the tag value of two-way horizontal scale, such as：The length scale of fixed band from 300mm beginning labels,
Terminate to 400mm, corresponding tag value is 1-10, and scale least unit is 10mm；Left and right two at fixed belt length 250mm
Horizontal scale is arranged in side, and the slave 30mm beginning labels of horizontal scale terminate to 40mm, and corresponding tag value is 1-10, in this way
It can direct read-out electrode positional value, it is not necessary to carry out above-mentioned calculating again, simplify operation sequence, as shown in Fig. 3,4,5,6, work as length
When degree scale value is 6, the positional value of horizontal electrode and vertical electrode is 6.
The program also has a clear advantage：Some useless scales can be weeded out.Because human body head circumference is usually one
It will not be zero in fixed range, therefore, some useless scales can be removed.
But different crowd has different head circumference length, if sharing fixed band, there is fixed with long, use not side
Just the problem of, therefore, experiment of the inventor by deep theoretical research and repeatedly, it is proposed that should be according to fixed strip length scale
