Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in more detail.
The multi-electrode proving installation that the embodiment of the present invention provides, measuring principle circuit connection diagram as shown in Figure 1, comprises pcb board 11, is arranged on slotted line, multiselect one electronic switch 12, tester 13, power supply 14 on pcb board.Described slotted line is provided with a plurality of, described pcb board 11 is connected with multiselect one electronic switch 12, described slotted line is connected between described tester and described multiselect one electronic switch in parallel, and described multiselect one electronic switch 12 is for controlling the disconnection and closure between described slotted line and described tester 13; Described power supply 14 is connected in series in circuit, and when multiselect one electronic switch 12 closures make a slotted line and circuit turn-on, described power supply 14 provides electric energy to whole circuit.Electrode to be measured one side of the present embodiment contacts with described tester 13, opposite side contacts with described pcb board 11, by multiselect one electronic switch 12, make an electrode in a slotted line, multiselect one electronic switch 12, power supply 14, tester 13 and the described electrode group in described slotted line form the circuit being communicated with, it is path, by tester, measure the now situation of circuit, just can draw the electric property of the electrode that path is therewith corresponding.
Fig. 2 has shown the schematic diagram that multiselect one electronic switch 12 is connected with slotted line.Multiselect one electronic switch 12 comprises a plurality of passages 121, and each slotted line 111 connects and only connect a passage, when the some passages 121 of plug-in strip 122 conducting of switch, and the also circuit part conducting with plug-in strip 122 1 sides by this channel attached slotted line 111.
Fig. 3 is slotted line and the electrode connection diagram of the embodiment of the present invention.Described slotted line 111 is with very little spacing parallel arrangement, and this spacing is not less than 1/2nd of the effective width value of electrode in slotted line vertical direction.Concrete, described electrode effective width is about 0.4-0.6mm, and therefore, the spacing between two adjacent described slotted lines 111 is no more than 0.3mm, further, is no more than 0.1mm.Preferably, described slotted line 111 is arranged in described pcb board equal intervals, and the distance between adjacent two described slotted lines 111 is about 0.1mm.
When measuring the electric property of artificial cochlea electrode, artificial cochlea's electrod-array both sides are contacted with the slotted line of tester and pcb board respectively, and make electrode connecting line substantially vertical with described slotted line direction.By described multiselect one electronic switch, by the conducting one by one of described slotted line, because the spacing between adjacent described slotted line is less than 1/2nd of the effective width value of electrode in slotted line vertical direction, so each electrode at least contacts with a slotted line.When the slotted line that certain electrode contacts passes through multiselect one electronic switch conducting, this electrode, in a path, now passes through described tester, the switching situation of test circuit, just can know the conduction status of electrode, and can test other electric property of electrode.
Optionally, the way of described multiselect one electronic switch is that port number is identical with the number of described slotted line; Be that described multiselect one electronic switch is that N selects a switch, N is identical with the number of described slotted line.
Further, the invention provides a kind of multi-electrode method of testing, the method adopts the multi-electrode proving installation described in embodiment before the present invention to measure, and the electric properties such as the conducting of electrode, contact are tested.
As an embodiment, multi-electrode method of testing flow process provided by the invention as shown in Figure 4, comprises the steps:
Step 1: electrode is contacted with slotted line.In this step, artificial cochlea electrode array and slotted line are to the placement of 45 °-90° angle, electrod-array both sides are contacted with slotted line with tester respectively.
Step 2: the 1st slotted line of conducting: by the 1st the corresponding electronic switch of the slotted line road conducting on pcb board.Multiselect one electronic switch that the present embodiment adopts, comprises a plurality of passages, by switching the plug-in strip of multiselect one electronic switch, and can the different passage of conducting.Because each electrode at least contacts with a slotted line, when slotted line conducting with certain electrode contact, the electrode of slotted line contact is in path.
Step 3: adopt tester to measure the electric current in current path, thereby obtain corresponding current value.
Step 4: judge whether current value surpasses the electrode conduction range of current of setting.In this step, according to the electric current that step 3 is measured, circuit turn-on situation is measured, if prove the not conducting of current circuit when electric current is greater than 2mA, entered step 41; If electric current proves and enters step 42 by electrode conduction when to be 0.5-2mA above.
Step 41: record current value exceeds number of times the judgement of described scope; If conducting number of times does not surpass the maximum slotted line numerical value in predefined interval continuously, judge the not conducting of the corresponding electrode of slotted line; If the number of times of conducting does not surpass the maximum slotted line numerical value in predefined interval continuously, enter step 5.The maximum slotted line numerical value in described interval, the meaning is in the present embodiment, owing to there being interval between electrode, therefore after artificial cochlea's electrode contacts with pcb board, some slotted lines may just in time fall into electrode interval and not with electrode contact, may fall into the maximal value of the slotted line number of electrode gap, i.e. the maximum slotted line numerical value in above-mentioned interval.For example, between adjacent electrode, be spaced apart 0.2mm, between slotted line, be spaced apart 0.1mm, the maximum slotted line numerical value in Zhong，Ji interval, interval that has at most two slotted lines to fall into adjacent electrode is 2.
Step 42: by tester, electrode is carried out the electrical performance testings such as impedance measurement, enter step 5.If current circuit turn-on is measured and is detected required other electric property of electrode by tester in step 42.
Step 5: whether judgement also exists the slotted line not connected in this measuring process, if so, by multiselect one switch successively order by next slotted line conducting and return to step 3, otherwise enter step 6.
Step 6: test finishes.
As can be seen from above, multi-electrode proving installation provided by the present invention, adopt little spacing to divide other slotted line, guarantee that each electrode at least contacts with a slotted line, can be applicable to the test of the electric properties such as conducting of artificial cochlea electrode array, also can be applied to that test target is little, test target interval is little and test target interval may irregular other occasion.
Those of ordinary skill in the field are to be understood that: the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
