Abstract
The invention discloses a kind of eye electrodes, belong to medical equipment technical field, including contact site and transport part, the contact site includes at least one in circular thin slice, thin slice, which is used to be positioned over, receives eye electric potential signal on the cornea of patient, transport part is the conducting wire being connected to contact site, is sent out eye electric potential signal by conducting wire.The present invention can be placed directly on cornea by the way that receiving part is set as circular, make reception signal stabilization, simultaneously as being flake structure, patient will not be by any stimulation, it can blink during the test and eliminate visual fatigue, the accuracy for improving detection, in addition, due to being flake structure, there is certain intensity in width direction, deform it is small, avoid the problem that the prior art exist winding, improve testing reliability and accuracy.
Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of eye for carrying out visual function test to patient
Electrode.
Background technology
When carrying out visual function test, it usually needs multiple electrodes react the health condition of patient with different paths.In test
Electrode include at least eye electrode.There are two types of existing eye electrode is usual：One is thin-wire electrodes, and one is heavy gauge wires
Electrode, thin-wire electrode generally use and the metallic fiber of hairline size are made, small to Ocular irritation, can be positioned over cornea
On, and a circle can be made, signal stabilization, but since diameter is small, spatial position is uncertain, there are problems that winding；Heavy gauge wire electricity
Generally use thicker conducting wire in pole is made, and since its diameter is thicker, there are higher intensity, will not mutually wind, but diameter compared with
Slightly, it cannot be positioned on cornea, can only be fixed on palpebra inferior, be easy to be interfered by eyelid muscle jitter, signal is not sufficiently stable, together
When, a circle can not be made, signal stabilization is poor.
The above-mentioned equal existing defects of eye electrode, it is necessary to the electrode of the prior art is improved, stable current potential is obtained
Signal, the accuracy to improving detection have larger help.
Invention content
In view of this, the present invention provides a kind of eye electrode for the drawbacks described above of the prior art, it is existing thin to solve
Lead electrode has that winding influences test accuracy.
The purpose of the present invention is what is be achieved through the following technical solutions：
Including mirror holder and temple, including contact site and transport part, the contact site includes at least one in the thin of annular shape
Piece, thin slice, which is used to be positioned over, receives eye electric potential signal on the cornea of patient, transport part is the conducting wire being connected to contact site, is passed through
Conducting wire sends out eye electric potential signal.
Further, the thickness of the thin slice is 0.02-0.12mm.
Further, a diameter of φ 0.02-0.12mm of the conducting wire.
Further, the width of the thin slice is 0.2-1mm.
Further, the internal diameter of the formed annulus of the thin slice is 3mm-8mm.
Further, there is the arc being adapted with human cornea on the width of thin slice.
Further, the contact site further includes the supporting course being arranged in thin slice upper surface.
Further, the thin slice is the coat of metal being plated on supporting course.
The beneficial effects of the invention are as follows：
The present invention can be placed directly on cornea by the way that receiving part is set as circular, make reception signal stabilization, together
When, due to being flake structure, patient will not be by any stimulation, and can blink elimination visual fatigue during the test, improve detection
Accuracy there is certain intensity in width direction, deformation is small, and the prior art is avoided to exist in addition, due to being flake structure
The problem of winding, improves testing reliability and accuracy.
Other advantages, target and the feature of the present invention will be illustrated in the following description to a certain extent, and
And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke
To be instructed from the practice of the present invention.The target and other advantages of the present invention can by following specification realizing and
It obtains.
Description of the drawings
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
The detailed description of one step, wherein：
Fig. 1 is the schematic three dimensional views of the present invention；
Fig. 2 is the front view of first embodiment of the invention；
Fig. 3 be Fig. 2 along A-A to cutaway view Amplified image；
Fig. 4 is cutaway view Amplified image of the second embodiment of the invention at contact site.
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 3, a kind of eye electrode provided by the invention, including contact site 1 and transport part 2, contact site be
One in circular thin slice 3, thin slice is made of metal material, and eye current potential letter is received for being positioned on the cornea of patient
Number, transport part is the conducting wire being connected to contact site, is sent out eye electric potential signal by conducting wire.To improve the adaptation of eye
Property, the thickness of the present embodiment thin slice is set as 0.02-0.12mm, and the diameter of conducting wire is set as φ 0.02-0.12mm, meanwhile, it will
The width of thin slice is set as 0.2-1mm, in actual use, can be selected as needed.Thickness is set as 0.02-0.12mm,
The diameter of conducting wire is set as φ 0.02-0.12mm, can improve the comfort of patient as far as possible, and the width of thin slice is set as 0.2-
Smaller width can be used to microphthalmus patient in 1mm, and larger width can be used in macrophthalmia patient, so can both improve patient and relax
Adaptive can improve signal stabilization again.
The present embodiment can be placed directly on cornea by the way that receiving part is set as circular, make reception signal stabilization, together
When, due to being flake structure, patient will not be by any stimulation, and can blink elimination visual fatigue during the test, improve detection
