Embodiment
Above-mentioned nondestructive test device is applied to the test of an artificial cochlear implant by the present embodiment, and the artificial cochlea plants
The electrod-array for entering body includes 22 accurate electrode contacts, is the critical component of artificial cochlear implant.To implant electrical property
The measurement of energy must connect 22 electrode contacts, i.e. main electrode 5 includes 22 electrode retaining collars 3, and conventional connection type all can be to electricity
Pole array causes irreversible damage, and the utility model can realize non-destructive testing.
In the present embodiment, main electrode 5 includes 22 electrode retaining collars 3, electrode ring width 0.3mm, and the insulation between electrode retaining collar applies
Slice width degree 0.6mm.256 turmeric conductive gates 1, grid width have been printed in the region of the positive 38.3mm of gate control circuit board 12
0.05mm, the width 0.1mm at grid interval 2,12 back side of gate control circuit board are the gate control circuit 9 for handling 256 grid, control electricity
Road 9 includes control switch, and gate control circuit output 13 controls 256 road grid channels and is connected with load resistance 7, and load resistance reconnects
To snail External Reference electrode 6, final circuit to decoder chip 10.90% physiological saline is filled out in the region of 38.3mm wide, is made
Conductive gate and electrode retaining collar come into full contact with, and the conductive gate under insulating coating is connected also by 90% physiological saline with electrode retaining collar.
Based on each width numerical value above, theoretically, there are two types of the ways of contact between electrode retaining collar and conductive gate, such as Fig. 2-Fig. 4
It is shown.Fig. 2 and Fig. 3 is the way of contact one, when having 2 conductive gates under electrode retaining collar, has 4 conductive gates under insulating coating.Fig. 4 is to connect
Touching mode two when having 3 conductive gates under electric electrode retaining collar, has 3 conductive gates, the conductive gate of the two sides under electrode retaining collar under insulating coating
It does not come into full contact with, 2 conductive gates come into full contact with.
In the way of contact once because the distance of conductive gate and electrode retaining collar under insulating coating is greater than the conduction under electrode retaining collar
The distance of grid and electrode retaining collar, it is assumed that the resistance of conductive gate and electrode retaining collar under insulating coating is Rx, the conductive gate under electrode retaining collar with
The resistance of electrode retaining collar is Ry, and Rx is greater than Ry, and Rx and electrode retaining collar are bigger at a distance of more remote then resistance value.
Assuming that give No. 1 electrode discharge (opening the grid channel of front 6, close other grid channels), Rx, Ry totally 6 can be calculated
A voltage value, voltage value is trapezoidal slope, as shown in figure 5, upper end two level conduction gate voltage Vx1, Vx2 are under electrode retaining collar
Gate voltage, 4, slope Vy1~Vy4 are the gate voltage under insulating coating.It is possible thereby to record the conductive gate of No. 1 electrode.It gives again
No. 2 electrode discharges (opening the road (7-12) grid channel, other closings), can calculate Rx, Ry totally 6 voltage values, at this time 3-12 again
A voltage value Vy1~Vy4, Vx3, Vx4, Vy5~Vy8 should be at trapezoidal profile (upper two or so each four), as shown in fig. 6, trapezoidal
Upper end be grid channel voltage under No. 2 electrode retaining collars, trapezoidal the right and left is the grid channel voltage under insulating coating.No. 2 electricity
There is insulating coating on pole both sides, there is 4 conductive gates under each insulating coating, and corresponding No. 1 electrode of its left side insulating layer is the right
Conductive gate, for No. 1 electrode, the conductive gate under insulating layer is remoter from electrode from the right, and the distance of intermediate physiological saline is got over
Far, physiological saline bring resistance is bigger, but for No. 2 electrodes, the distance closer to No. 2 electrode physiological saline is got over
It is small, the resistance value of physiological saline is smaller and No. 1 electrode on the Ry resistance value size that calculates it is opposite.Based on electrode retaining collar and insulating coating
Difference can derive which conductive gate is below electrode by calculating, which conductive gate is below insulating coating, thus
Turn off the grid channel under insulating coating by gate control circuit, the grid channel only retained under electrode retaining collar is connected with load resistance.According to
It is secondary to analogize, calculate the corresponding grid channel of remaining 22 electrode retaining collars.
Under the way of contact two, for second conductive gate and most short, the 2nd~6 distance of electrode retaining collar distance under electrode retaining collar 1
It is primary to elongate.Assuming that give No. 1 electrode discharge (opening the grid channel of front 6, close other grid channels), Rx, Ry totally 6 can be calculated
A voltage value, as shown in fig. 7, voltage sequence figure is 1,2 to go up a slope, 2-6 descending, 1~3 is the gate voltage under electrode retaining collar, 4~6
For the gate voltage under insulating coating.It is possible thereby to record the conductive gate of No. 1 electrode.And so on, calculate remaining 22
The corresponding grid channel of electrode retaining collar.
It can be seen that may determine that the position sum number of conductive gate under electrode retaining collar according to test result under identical discharge scenario
Mesh calculates the conductive gate difference under electrode retaining collar and insulating coating, so that the grid channel under turning off insulating coating, only retains electrode
Grid channel under ring is connected with load resistance.Specifically, if voltage value is Trapezium oblique wave, the way of contact is Fig. 2 or Fig. 3；If
Voltage value is descending after first going up a slope, then the way of contact is Fig. 4.Main electrode is made of 22 electrodes, and 22 electrodes are mutually by insulating
Coating isolation, 22 electrodes need extraneous load circuit to be discharged and be independent, if contacting electrode with metal needle, can damage
Bad electrode changes by contact with normal saline electrode, and physiological saline cannot be distinguished 22 electrodes, place conductive gate under the electrodes, pass through
Gate control device calculates the conductive gate position under 22 electrodes, to distinguish 22 electrodes.
After the corresponding grid channel of 22 electrode retaining collars has been calculated, gate control circuit can save data, complete self-test.Test
When, it needs to test some electrode, the grid channel of other electrode retaining collars can be closed, only retain the grid channel that need to be tested.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
