Description
This utility model relates to a kind of electrode that is used for mapping heart and brain current potential.
At present, conventional epicardial potential mapping adopts bipolar control checking method, promptly adopts two electrodes (bipolar) to measure its potential difference to any mapping of heart table.This method is ignored the space between adjacent two counter electrode, if depolarization or conduction take place for zonule between two electrode pairs, then may adjacent two counter electrode all surveys less than, the i.e. comprehensive and degree of accuracy that influence is surveyed.And, this mapping electrode, its electrode points quantity must be abundant, and its electrode outlet line is exactly for a lot, and volume is bigger, causes confusion easily and fractures, and gives and uses the band trouble.In addition, the kind electrode price is also relatively more expensive.
The purpose of this utility model is to propose a kind of simple in structure, easy to use, precision height, the heart and brain current potential mapping electrode that cost is low.
The heart and brain current potential mapping electrode of this utility model design is made up of flexible printed circuit sheet, some electrode points and respective electrode lead and protective film; wherein; the convex shape of electrode points for exposing; and evenly be arranged in the flexible circuit sheet with m * n array way; 4≤m; n≤20, m is the line number of electrod-array, n is the number of every column electrode point.Each electrode draw that lead is also integrated to be arranged in the strip flexible circuit sheet.Protective film is covered on the printed circuit sheet.Electrod-array and electrode cable form integral structure by flexible printed circuit sheet, as shown in Figure 1 and Figure 2.Electrode outlet line can be connected with corresponding connector.
Electrod-array on the above-mentioned printed circuit sheet can adopt following two kinds of reasonable arrangement modes:
A kind of mode is the electrode points perpendicular alignmnet up and down of adjacent two row of electrod-array, becomes the ranks form, and line-spacing is all identical with the row distance, as shown in Figure 3.The electrod-array of this arrangement mode, it is square of 4 equidistant adjacent electrode points formations up and down.Therefore, claim that this arrangement mode is the square array form.
Another kind of mode is that the electrode points of adjacent two row of electrod-array becomes 60 degree angles to stagger up and down, and adjacent two electrode points of the lastrow electrode points corresponding with next line constitutes equilateral triangle, as shown in Figure 4.The electrod-array of this arrangement mode, the electrode points at position, intermediate portion (non-edge) 6 equidistant adjacent electrode points are arranged up and down, constitute a regular hexagon, be similar to cellular.Therefore, claim that this arrangement mode is the honeycomb array format.
Above-mentioned electrod-array can obtain m * n the one pole signal of telecommunication, promptly obtains the one pole mapping signal at each electrode points place.In addition, also can form bipolar lead to adjacent two electrode points in the array, obtain the differential electric signal in middle site between adjacent two electrode points, we are referred to as bipolar signal.For the square array form, its bipolar signal quantity is k=m (n-1)+(m-1) n=2mn-m-n.For the honeycomb array format, its bipolar signal quantity be k=m (n-1) n+ (m-1) (2n-1)=3mn-2 (m+n)+1.Like this, multiplexing by counter electrode improved the utilization rate to the electricity level greatly.Thereby can make more a spot of electrode obtain abundant detection signal.For example, when m=n=8, press the square array form, its unipolar signal has 8 * 8=64, and bipolar signal has 2 * 8 * 8-8-8=112, always has 176 signals.Press the honeycomb array format, its unipolar signal is 64, and bipolar signal is 3 * 8 * 8-8-8+11=161, always has 225 signals.And, only can obtain 32 bipolar signals if adopt conventional bipolar mapping.
Electrode points and lead can adopt photoetching process to be made on the flexible printed circuit sheet in this utility model.Each electrode points dimpling, it highly is 0.1～0.3mm, so that it contacts well with tested tissue.The diameter of electrode points is selected for use in 0.5～2mm, and the centre distance of adjacent two electrodes is 2.0～8.0mm, can adapt to the mapping needs of different accuracy.Electrode surface can gold-plated or platinum plating.The drawing lead and can do very carefully of electrode, for example, its width is 0.08～0.15mm.Like this, its electrod-array can be done very for a short time, and for example 8 * 8 electrod-array can be produced on the square flexible circuit sheet of 5 * 5cm (band edge frame), and the drawing lead and can be produced on the rectangular flexible circuit sheet of 2.2cm width of electrode, and become integrated structure.
The electrode of this utility model design is mainly used in the mapping of the current potential of heart and brain.Its pole piece can adapt to the measurement situation needs of the heart (brain) electricity under the situation of above-mentioned array arrangement, be made into corresponding shape.
When using this utility model, each electrode outlet line is connected with amplifier,, with relevant analytical tool connection, obtains the mapping result then to amplify detectable signal.
The mapping electrode of this utility model design is compared with traditional electrode has following superiority:
1. owing to the array structure of electrode points, make arbitrary measurement point and adjacent spots constitute a plurality of measurements and lead, improved the utilization rate of electrode greatly.Under the situation that satisfies identical mapping signaling point, can reduce electrode points quantity, simplified structure dwindles the volume of electrode, reduces the cost of electrode, and the cost of this electrode only is 1/tens of a conventional electrodes cost, can be used as the disposable medical devices and uses.
2. electrod-array and draw lead and become integrated structure by flexible printed circuit sheet, and can utilize photoetching process to make, make the electrode microminiaturization, and size is accurate, lead-out wire can not fracture, sealing-off, connects to stablize, and profile is very thin, easy to use, good reliability, mapping precision height.
3. because electrode points is equidistantly arranged, each is measured passage and is equal on the amplitude information that obtains depolarization ripple (Depolarazationwave).And the orientation difference of adjacent two electrodes (for example is level, vertical, or+60 °,-60 ° of orientations) can find out the depolarization ripple that transmits from different directions, and can elicite in electrode module overlay area all depolarizations and involve direction and the amplitude that wavelet is transmitted, can obtain omnibearing information.This research and focus location to for example atrial fibrillation or epilepsy journalist is very useful.
