Description
Technical field
This utility model relates to a kind of stimulating electrode device, relates more specifically to a kind of stimulating electrode for auditory evoked potential test.
Background technology
Auditory evoked potential is a kind of method of objective evaluation auditory function situation.It is being listened domain measurement, hearing loss to evaluate and is having important value in Auditory Pathway pathological changes diagnosis etc.Auditory brainstem response be Sound stimulat bring out acoustic nerve and brain stem nerve nucleus at different levels electricity reaction.It can react the activity of internal ear function and brain stem maincenter at different levels, and the impact of the not subjective behavior of tested person person, be a kind of objective, reliable detection method.Electricity irritation auditory evoked potential technology is the preoperative residual hearing of assess patient " goldstandard ", is the key technology whether preoperative evaluation deafness patient is applicable to implanting cochlear implant operation.But due to the amplitude usual very little (being generally 0.5-1uv) of evoked brain potential, and be submerged in its high spontaneous brain electricity of Amplitude Ration, therefore the acquisition and display of evoked brain potential is a great problem for a long time always.Although have a lot of research to the technology of electricity irritation auditory evoked potential test abroad, the research about the stimulating electrode of electricity irritation auditory evoked potential test use is but blank substantially.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of safety, Wicresoft, has good capacitive character and histocompatibility, good pliability and stimulating electrode with low cost.
Stimulating electrode for the test of electricity irritation auditory evoked potential described in the utility model, comprising: platinum wire, and it forms for multiply platinum wire is stranded, has the first end for inserting cochlea and the second end being connected copper core electrode wire; It utilizes the good pliability of platinum wire, reduces chance auditory meatus being formed to wound.
Insulating barrier, it is coated on the skin of described platinum wire;
Wherein, described first end is spherical, and is exposed to outside described insulating barrier.Described first end such as utilizes high temperature to be fused into platinum ball through platinum wire.According to auditory nerve in i-coch distribution situation, be set to spherical by the first end of stimulating electrode, ball-shaped end, compared to prior art, has the stimulation face of larger three-dimensional, 360 omnibearing stimulations being formed to auditory nerve, laying the foundation for obtaining test structure accurately.
Preferably, the diameter of described spherical first end is 0.2-0.3mm.Find after deliberation, when the diameter of spherical first end is 0.3mm, its test result is more accurate.
Preferably, described insulating barrier is layer of silica gel.Described layer of silica gel improves the histocompatibility of described stimulating electrode, reduces the injury to patient.
Preferably, the length of described platinum wire is 19-21cm.
During use, the described stimulating electrode for the test of electricity irritation auditory evoked potential coordinates two needle electrodes, and be placed in cochlea by the described first end being used for the stimulating electrode of auditory evoked potential test, the second end connects electrostimulator, and two needle electrodes are placed in subcutaneous.Control electrostimulator by processor and send stimulus signal, stimulating electrode sends stimulation to auditory meatus, completes the test of electricity irritation auditory evoked potential.
Stimulating electrode for auditory evoked potential test described in the utility model, the material of use safety, there is good capacitive character and histocompatibility, good pliability and as much as possible invasive, make stimulating electrode both can undertake the electricity measuring electricity irritation auditory evoked potential, avoid again causing damage to body, can high-temperature sterilization, Reusability, reduces costs.
Accompanying drawing explanation
Fig. 1 for described in one of them embodiment of this utility model for the structural representation of stimulating electrode of auditory evoked potential test.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail, can implements according to this with reference to description word to make those skilled in the art.
As shown in Figure 1, the stimulating electrode for auditory evoked potential test described in the utility model comprises: platinum wire 1, and it forms for multiply platinum wire is stranded, has the first end 11 for inserting cochlea and the second end 12 being connected copper core electrode wire; The length of described platinum wire is 19-21cm.
Insulating barrier 13, it is coated on the skin of described platinum wire; Described insulating barrier 13 is layer of silica gel.Described first end 11 is spherical, and exposes with outside described insulating barrier.Described first end such as utilizes high temperature through platinum wire warm one-tenth platinum ball 11.The diameter of described platinum ball 11 is 0.3mm.
Wherein in an embodiment, described platinum wire 1 becomes one by multiply platinum wire twisting, and length is such as 21cm, external application SOI glue-line 13, first end 11 high-temperature molten with become platinum ball electrode, the spheric electrode of diameter 0.3mm surface naked layer, the second end 12 connects conventional copper core electrode wire 14.
During use, the described stimulating electrode for auditory evoked potential test coordinates two needle electrodes, and be placed in cochlea by the described platinum pommel being used for the stimulating electrode of auditory evoked potential test, the second end 12 connects electrostimulator, and two needle electrodes are placed in subcutaneous.Control electrostimulator by processor and send stimulus signal, stimulating electrode sends stimulation to cochlea, completes the test of electricity irritation auditory evoked potential.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the general concept that claim and equivalency range limit, this utility model is not limited to specific details and illustrates here and the legend described.
