Background technology
High speed development along with science and technology, artificial cochlea's (electronic ear) development also obtains tremendous development. and the artificial cochlea is a kind of electronic installation, it is converted to the electric signal of certain coding form by external speech processor with sound, recovers, improves and rebuild deaf person's auditory function by the direct excited auditory nerve of the electrode system that implants.Nearly two during the last ten years, along with high-tech development, the artificial cochlea makes much progress, and enters clinical practice from experimental study, the whole world is deaf to complete deafness conventional method as treatment severe the artificial cochlea now, and the artificial cochlea uses the most successful bio-medical engineering equipment at present.The application of implanting along with the artificial cochlea more and more widely, the detection problem of device outside is even more important during the postoperative start, with regard to known case, because device outside (speech processor) is operate as normal or abnormal work not, testing impedance is unusual before causing starting shooting, even in the machine of the accent process human body is caused life harm.Have these problems for prior art, develop a special detection artificial cochlea transmitting coil whether the device of operate as normal be necessary.
Prior art adopts the actual implant that uses as the RF testing apparatus that transmits, the problem that exists is: it is aging easily that implant is of long duration, can produce impedance after the surface of contact oxidations such as solder joint and cause error, so the radiofrequency signal test error of speech processor is bigger, and the signal measurement of test point is that manually point is surveyed, angle difference between the oscilloprobe also can have influence on the precision of measurement, and the difference of each probe engaged test point position also can have influence on measuring accuracy.Especially different implants has certain electric property difference, after the implant for the production of test usefulness damages, change can make behind other implants before a collection of and back a collection of speech processor radiofrequency signal amplitude certain difference be arranged, influence the accuracy of testing.
The utility model content
The purpose of this utility model is a kind of RF signal-testing apparatus for artificial cochlea's transmitting coil that provides at the deficiencies in the prior art, adopt the test chip circuit signal that receives to be shown the parameter of direct read test by oscillograph, judge directly perceived, easy to use, the measuring accuracy height, and simple in structure, improved normal accent machine and the work efficiency of artificial cochlear implant greatly.
The concrete technical scheme that realizes the utility model purpose is: a kind of RF signal-testing apparatus, be characterized in that this pick-up unit is made up of the phase magnet that is arranged on upper plate, two calibrating terminals, fixed terminal, signal receiving area and the receiving coil and the test circuit that are arranged on lower plate, described receiving coil be arranged on test circuit the top and with test circuit for electrically connecting; Described signal receiving area is arranged on the upper plate corresponding with receiving coil; Described fixed terminal is to be arranged on the adjustable geometrical clamp of upper plate underclearance; Described two calibrating terminals are arranged on the top of fixed terminal and are electric connection with test circuit; Described phase magnet is arranged on the central authorities of signal receiving area and fixedlys connected with upper plate; Described upper plate is provided with the waist hole with the fixed terminal adjustable gaps, upper plate by screw be fixed on lower plate on.
Described fixed terminal is made up of right angle trigonometry piece and two straight flange bars, and right angle trigonometry piece and two straight flange bars are fixed on the upper plate by bolt and waist hole.
The utility model shows the directly parameter of read test by oscillograph, compared with prior art has judgement fast, intuitively, the measuring accuracy height, simple in structure, easy to use, improved normal accent machine and the work efficiency of artificial cochlear implant greatly, further improve the reliability of implant.

Embodiment
Consult accompanying drawing 1 ~ Fig. 2, the utility model is made up of the phase magnet 3 that is arranged on upper plate 1, two calibrating terminals 6, fixed terminal 7, signal receiving area 10 and the receiving coil 4 and the test circuit 5 that are arranged on lower plate 2, described receiving coil 4 be arranged on test circuit 5 the top and with test circuit 5 for electrically connecting; Described signal receiving area 10 is arranged on the upper plate 1 corresponding with receiving coil 4; Described fixed terminal 7 is for to be arranged on the adjustable geometrical clamp of upper plate 1 underclearance, and fixed terminal 7 is made up of right angle trigonometry piece 8 and two straight flange bars 9, and right angle trigonometry piece 8 and two straight flange bars 9 are fixed on the upper plate 1 by bolt 16 and waist hole 11; Described two calibrating terminals 6 are arranged on the top of fixed terminal 7 and are electric connection with test circuit 5; Described phase magnet 3 is arranged on the central authorities of signal receiving area 10 and fixedlys connected with upper plate 1; Described upper plate 1 is provided with the waist hole 11 with fixed terminal 7 adjustable gaps, upper plate 1 by screw 15 be fixed on lower plate 2 on.
Consult accompanying drawing 3, described upper plate 1 is provided with the waist hole 11 with fixed terminal 7 adjustable gaps, waist hole 11 can make things convenient for the adjusting of two straight flange bars 9 and right angle trigonometry piece 8 distances, each measurement with the oscillograph test probe of guaranteeing the different size model can both contact reliable and position and fixed angle with calibrating terminal 6, the test error that the human factor of avoiding produces.
Consult accompanying drawing 4, the utility model is to use like this: two test probes 13 are connected with two calibrating terminals 6 respectively and are fixedly clamped by fixed terminal 7, two straight flange bars 9 are adjustable with the distance of right angle trigonometry piece 8, the oscillograph test probe of applicable different size model, make the test point of two test probes 13 after fixing be 90 ° of angles, can avoid the test error that causes owing to the difference that takes measurement of an angle like this, to need the transmitting coil 14 of test signal to be placed on the signal receiving area 10 and the enabling signal emission then, the direct parameter of read test of oscillograph 12 this moment, convenient test, intuitively.The phase magnet 3 of signal receiving area 10 central authorities and 17 of the magnet of transmitting coil 14 play fixing spacing effect, it all is same position in the time of can guaranteeing to place at every turn, and 10 surfaces, signal receiving area are level altitude with receiving coil 4, can avoid owing to placing the error that distance causes, measuring accuracy height.
