Circle, signal stabilization, but since diameter is small, spatial position is uncertain, there are problems that winding, signal are not sufficiently stable.
In view of the above-mentioned problems, it is necessary to be improved to thin-wire electrode, it is made not wind, stable current potential can be 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, using memory material system
At, there is shape memory function, make that specific shape can be kept in testing, it is indeformable not wind, to solve existing thin wire
Electrode has that winding influences test accuracy.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of eye electrode with shape memory function, including contact site and transport part, the contact site are using shape
Closed-loop made of shape memory material, the closed-loop, which is positioned on patient's cornea, becomes regular circular reception eye current potential letter
Number, transport part is the conducting wire being connect with contact site, is sent out eye electric potential signal by conducting wire.
Further, the shape-memory material is conductive material.
Further, the conductive material is alloy material.
Further, the section of the closed-loop is circle.
Further, the diameter of section of the closed-loop is φ 0.02-0.12mm.
Further, the diameter of the conducting wire and the diameter of closed-loop are identical.
Further, the closed ring at circular a diameter of φ 3-8mm.
The beneficial effects of the invention are as follows:
The present invention has shape memory function, makes the shape that can keep rule in testing, indeformable not wind, and solves
The prior art has that winding influences test accuracy;Shape memory of the present invention is circle, can 360 degree of omnidirections reception letters
Number, make reception signal comprehensively, exhaustive, can further improve the accuracy of detection.
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 structural diagram of the present invention;
Fig. 2 is the schematic diagram when present invention uses.
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, a kind of eye electrode with shape memory function provided by the invention, including contact site 1 and biography
Defeated portion 2, contact site are using closed-loop made of shape-memory material, the phase transition temperature and human body temperature of the shape-memory material
It is adapted, closed-loop is made to be positioned on patient's cornea, shape memory effect can be generated under body temperature effect, by irregular
Shape become regular circular, so as to receive eye electric potential signal in the orientation of 360 degree of cornea, as shown in Fig. 2, transmission
Portion is the conducting wire being connect with contact site, is sent out eye electric potential signal by conducting wire, specifically, the present embodiment shape memory
Material is made of conductive alloy material, such as:Au-Cd、Ag-Cd、Cu-Zn、Cu-Zn-Al、Cu-Zn-Sn、Cu-Zn-Si、Cu-
Sn, Cu-Zn-Ga, In-Ti, Au-Cu-Zn, NiAl, Fe-Pt, Ti-Ni, Ti-Ni-Pd, Ti-Nb, U-Nb and Fe-Mn-Si etc.,
And its phase transition temperature is 36-40 degrees Celsius.
The conducting wire of the present embodiment can be aluminum steel, copper wire etc., the preferred copper wire of the present embodiment, can be by the side that is fastened
Formula is realized with closed-loop and is connected, naturally it is also possible to is integral by being welded and fixed with closed-loop.
The contact site made of the above-mentioned material with shape memory function, and phase transition temperature is set as 36-40 and is taken the photograph
Family name's degree, the shape of rule can be kept by making eye electrode in testing, indeformable not wind, and solve the prior art and there is winding shadow
The problem of ringing test accuracy;Meanwhile shape memory is defined as circle, can 360 degree of omnidirections receive signals, make reception signal
Comprehensively, without loss, it can further improve the accuracy of detection.
As the improvement of the present embodiment, the section of closed-loop is circle, and the periphery of round sealed ring will not be damaged without corner angle
Cornea is conducive to improve safety, while circular configuration is also conducive to the transmission of signal.
Further, a diameter of φ 0.02-0.12mm of conducting wire, close with the diameter of hairline, eye sensibility is weak, stimulation
Small, patient can be blinked in testing to alleviate visual fatigue, be conducive to improve test accuracy and reliability.
As the improvement of the present embodiment, the diameter of closed-loop is identical as the diameter of conducting wire, and signal transmission section is made not occur
Mutation, signal will not be lost, and testing result is more reliable.
As the improvement of the present embodiment, closed ring at round diameter be φ 3-8mm.It is conducive to be formed and human body angle in this way
The signal receiving area that film size matches, to improve the accuracy for receiving signal.
Finally illustrate, the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to compared with
Good embodiment describes the invention in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the present invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of the technical program, should all be covered in the present invention
Right in.
