Abstract
The invention discloses an electrode placing device of an of electrical impedance tomography, which comprises an insulating board, electrodes, electrode probes and an elastic pull-down system, wherein the multiple electrodes are arranged on the insulating board; the probes are arranged at the tail ends of the electrodes; and the elastic pull-down system is arranged at the outer side of the insulating board. The electrode placing device disclosed by the invention can be in better contact with the surface of a detected object and has good electric conduction performance; and because the shape structure is stable, the repeatability is excellent.
Description
Technical field
The present invention relates to a kind of animal brain electrode apparatus for placing, particularly a kind of electrode apparatus for placing that is used to carry out animal brain electrical impedance tomography experimentation.
Prior art
At present, in the electrical impedance tomography technical research, the electrode setting method of laboratory animal brain is attachment of electrodes or screw is fixed one by one; Though contact reliable for effect, fixing maneuver complexity, especially the screw fixation is destroyed greatlyyer to the animal skull, careless slightlyly both may destroy the animal cerebral dura mater, makes the experimental data distortion; And electrical impedance imaging technology counter electrode lay permutation matrix require high, about lay asymmetric, lay the maneuver weight and all can influence experimental data, have significant limitation so maneuver is laid electrode.
Summary of the invention
The objective of the invention is to overcome the shortcoming that existing maneuver is laid electrode, a kind of simple and easy to do animal brain electrical impedance tomography electrode apparatus for placing is provided, improve conventional efficient and repeatability.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
A kind of electrical impedance tomography electrode apparatus for placing comprises pull system under insulation board, electrode, electrode probe and the elasticity; Described insulation board is provided with several electrodes, is provided with probe at electrode end; The flexible pull system down of described insulation board arranged outside.
Described insulation board is disk, square plate, oval plate or diamond pad, and the positive center of insulation board is provided with a through hole as required, and this through hole is circular, square, ellipse or rhombus.
Position relative fixed between the described electrode probe.
Be connected with conductor wire on the described electrode.
Described insulation board is made by electrically non-conductive material, and electrically non-conductive material is seasoned wood or PVC plate.
Animal brain electrical impedance tomography electrode apparatus for placing of the present invention comprises insulation board, outside traction pull system and be arranged on electrode probe on the insulation board down.But this electrode probe free adjustment length makes its convenient and tight laboratory animal calvarium portion that is contacted with; The flexible pull system down of outer setting makes this electrode assembly tightly be pressed on animal calvarium portion, places the electrode slippage.
In the such scheme, described electrode has the characteristics of adjustable length, and the matrix relative position that distributes between the electrode is fixed.
Compared with prior art, advantage of the present invention is easy to operation, and fixed effect is reliable, and electrode contacts closely with the animal calvarium, and relative position is fixed between the electrode, and the experiment repeatability is very high.
Description of drawings
Fig. 1 is the structural representation of electrode assembly of the present invention;
Fig. 2 is the left view of electrode assembly of the present invention;
Wherein: 1 is insulation board; 2 is electrode; 3 is electrode probe; 4 is pull system under the elasticity; 5 is through hole.
The specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of animal brain electrical impedance tomography electrode apparatus for placing, comprise insulation board, outside traction pull system and be arranged on electrode probe on the insulation board down, but this electrode probe free adjustment length makes its convenient and tight laboratory animal calvarium portion that is contacted with; The flexible pull system down of outer setting makes this electrode assembly tightly be pressed on animal calvarium portion, places the electrode slippage.
As shown in Figure 2, during use, earlier electrode assembly is positioned over animal calvarium portion appropriate location, electrode assembly is fixed on the animal headstock with pull system under the elasticity, make its downwards and tissue tight of animal calvarium portion press together; Adjust the length of electrode, every electrode is all combined with tissue tight of calvarium portion.
After electrode assembly fixedly finishes, connect the detection lead in the electrode tail end, carry out electrical impedance and detect, both sides black elastic force rubber band is a pull system under the elasticity, the insulation board central authorities of electrode assembly leave a hole, wait operation so that carry out the injection of Medulla Leporis seu Oryctolagi portion.
Above content is to further describing that the present invention did in conjunction with concrete preferred implementation; can not assert that the specific embodiment of the present invention only limits to this; for the general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; can also make some simple deduction or replace, all should be considered as belonging to the present invention and determine scope of patent protection by claims of being submitted to.
