Description

Multiple tracks pin type electrode in the body cavity
This utility model relates to a kind of Physiological Experiment equipment, the particularly a kind of Electrocardiographic multiple tracks pin of measuring body intracavity type electrode that is used for.
Research and the generation of discussion electrocardio, propagation, heart potential field distribution mechanism common method are to adopt body surface fixed point mapping electrocardiogram; Utilize conduit etc. that people and/or animal are carried out the chambers of the heart and heart table mapping electrocardiogram.China's electrocardiology scholar professor YinBing Sheng etc. adopts the Electrocardiographic new method of body cavity mapping to carry out electrocardio research to animal in recent years, writes down out the electrocardiogram of animal body intracavity (by heart table between the body surface) first, and the electrocardio theoretical research is made substantial progress.But existing commercially available multiple tracks electrode can only be applicable to vitro detection, is not suitable for to measure endoceliac electrocardiogram.Needle electrode in the external similarly myocardial wall, cardiac catheter electrode are very meticulous, and complex manufacturing technology, cost an arm and a leg.
The purpose of this utility model be exactly for provide a kind of capacity of resisting disturbance strong, conduct electricity very well, make multiple tracks pin type electrode in simple, the cheap body cavity.
This utility model is to realize like this.
The whole oblique line shape pin type that adopts of this utility model is arranged or the arrangement of cylindric pin type, its end is an aciculiform, electrode adopts three roads, four roads, five roads, six roads, seven roads or eight roads, an electrode is together, be the insullac interlayer between adjacent two electrodes every, the periphery of electrode is even omnipotent glue-line parcel, its conductiving point of electrode that oblique line shape pin type is arranged is in line on the equidirectional needle-like that is arranged in oblique line directions, the electrodes conduct point that cylindric pin type is arranged on the same cross section of near needle end part, conductiving point place naked enamelled coating and omnipotent glue-line.
Oblique line shape pin type electrode total length and width are decided on number of electrodes, generally long 60~80mm, and width is 2~5mm, high (thick) degree is 1~2mm.Cylindric pin type electrode total length is 60~80mm, and diameter is decided on number of electrodes, is generally 1.5~2.5mm.The electrode body material is the little tinsel of polarization potential, is insulated by the insulation enamelled coating between the electrode, carries out bonding casting with all-purpose adhesive and makes admittedly.
(1) electrode material is immersed in 95% ethanol 1~3 hour, dry on the cleaning electrode surface.
(2) the electrode material needle body partly is immersed in the insullac 1~3 minute, mentions and be inverted fixingly, room temperature left standstill 5~8 hours, made unnecessary insullac flow to needle handle portion automatically and with its removing.
(3) electrode material is put into thermostatic drying chamber with 90 ℃ of bakings 16~20 hours, drying insulated paint.
(4) to can be made into three roads, four roads, five roads, six roads, seven roads, eight roads according to the experiment needs several for this utility model.An electrode is as one, and adjacent two electrodes have only one deck insullac to be separated by, and oblique line shape pin type electrode syringe needle fore-and-aft clearance is that adjacent two needle points distance is 1~3mm; Cylindric pin type electrode syringe needle horizontalization is neat, with line closely ligation become oblique line shape and cylindric arrangement to fix, repeat once (2) and (3) step.
(5) static line that will dry on the electrode is removed, and coats all-purpose adhesive equably, and room temperature leaves standstill air-set in 3 days, can cast oblique line shape pin type electrode and cylindric pin type electrode.
(6) remove the all-purpose adhesive and the insullac of each root electrodes conduct point with operation point of a knife or special steel knife taper, generally the exposure range diameter is 0.05~0.2mm, the equidirectional arrangement that is in line of each conductiving point of oblique line shape pin type electrode, and the conductiving point spacing can be 2~3mm.Cylindric pin type electrodes conduct point is on same cross section, and the conductiving point spacing can be 0.5~1mm.
This utility model is applicable to that mainly rat, Cavia porcellus, rabbit experiment animal carry out Electrocardiographic detection in the body cavity, according to the experimentation purpose, this electrode is inserted in animal cavity, and oblique line shape pin type electrode can be traced simultaneously in same orientation and same distance of heart and/or the different electrocardiogram that leads; Cylindric pin type electrode can be traced same as different azimuth and/or the different electrocardiogram that leads with heart simultaneously.For research with inquire into electrocardiogram generation, propagation, distribution mechanism and obtain the firsthand material.
Hardened this utility model be will cast and multiple tracks electrocardiogram or polygraph will be connected to lead, according to different research purposes, pin type electrode is inserted pre-reconnaissance in the body cavity,, and connect the reference electrode and the ground electrode of preliminary election at body surface as the exploring electrode of electrocardiogram lead.Oblique line shape pin type electrode inserts the endoceliac exploring electrode degree of depth and is close to skin with last root electrodes conduct point and exceeds.Like this since each small electrode (conductiving point) and heart apart from different, thereby in body cavity on the same test orientation, can record synchronously with heart different distance and/or the different electrocardiogram that leads.Cylindric pin type electrode inserts the endoceliac exploring electrode degree of depth to be determined according to experiment purpose, like this owing to conductiving point and the same distance of heart but different azimuth, thereby record respective graphical.
In the experimentation of carrying out body cavity electrocardiogram mapping, select for use five roads and eight road this utility model to trace head chest lead and Wilson lead electrocardiogram, in 33 new zealand rabbit experiments, 35~40 orientation of every rabbit test, first test point on skin is inserted body cavity with this utility model, observe synchronously with the heart different distance and/or with the head chest lead and the Wilson lead electrocardiogram of heart same distance different azimuth, the result is:
(1) on same test orientation, HC leads to lead with Wilson all following performance: the electrode nearest apart from heart record the electrocardiogram maximum, successively decrease successively, away from one electrode of heart (promptly being close to skin) record the electrocardiogram minimum.But various histoorgans are to electrocardio damping capacity difference on the different azimuth, and institute records to such an extent that the electrocardiogram amplitude is variant.
(2) on the identical distance of the same electrode in same test orientation, HC leads and the lead distribution of each wave amplitude and average of Wilson, and is quite similar at left breast, and the average that HC leads is led greater than Wilson; At right breast, both differ greatly.
(3) with a kind of lead and the different azimuth of same distance on ECG pattern significant difference can be arranged, the HC lead electrocardiogram is intends spherical distribution.
The above results shows: for improving further that HC leads and theoretical " intend spherical center of area current potential field wave front and transmit theory ", for research with inquire into aspect the mechanism that electrocardio produces and propagate, this utility model provides good laboratory facilities.
This utility model capacity of resisting disturbance is strong, it is simple, cheap to conduct electricity very well, make.
