Description

Cochlear implant electrode array coupling test device
Technical field
The utility model relates to the circuit performance proving installation, specifically a kind of cochlear implant electrode array coupling test device.
Background technology
The artificial cochlea is the highest a kind of electronic installation of present bionics scientific and technological content, is mainly used in to help to wear osophone effect bad or absolutely void utmost point severe, anacusia patient.It converts sound wave to faint current signal the artificial cochlea, and this current signal passed in the inner ear (cochlea), the acoustic fibers of electrode stimulating cochlea the inside diverse location, acoustic fibers is subjected to producing nerve impulse after the stimulation of electric current, and nerve impulse passed to brain, in brain, form the sense of hearing.
In whole artificial cochlea system, body is implanted into the part that device is a most critical, and the speech processor has only by it could stimulate acoustic fibers, realizes the recovery of the sense of hearing.Electrode array union among the artificial cochlea is directly to stimulate auditory nerve, and its electric property directly has influence on the effect of artificial cochlea implanting device, therefore in process of production, to the check of electrode array union, just seems very important.Diameter, test point spacing are little, soft is afraid of characteristics such as extruding because electrode array union itself has, so relatively more difficult to the electrode test of pole matrix.And existing electrode array union proving installation, it adopts spring probe that electrode is tested, the face of cylinder contact that probe elastic force is big, end of probe is not suitable for pole matrix, and the test point spacing is bigger, and the apparatus structure complexity is awkward and safeguards, very dangerous, production cost is also high.
Summary of the invention
The purpose of this utility model is a kind of cochlear implant electrode array coupling test device that provides at the deficiencies in the prior art, it adopts the bullet pin to solve the detection difficult point that the test point spacing is little, test block is elongated, soft fearness is pushed, improved the percent of call completed of test contact, and simple to operate, safety, safeguard very convenient.
The concrete technical scheme that realizes the utility model purpose is: a kind of cochlear implant electrode array coupling test device, characteristics are that it comprises that base plate, two plays needle stand, two and plays pin, one plays needle stand for vertically being provided with the rectangular block of several parallel needle trays, and one jiao of rectangular block is provided with the groove that intersects vertically with needle tray; Another plays needle stand is rectangular block, and its end face is provided with chute, the affixed adjustable plate in side, is provided with the slide block of several parallel needle trays in the chute; Two play needle stand is arranged on the base plate by screw retention in twos relatively; Two bullet pins are that several and parallel two rows are arranged in two needle trays one end and base plate welding; Affixed plug socket under the base plate.
A described bullet pin is the elongated copper wire that an end is provided with flanging.
It is the elongated copper wire that two ends are provided with flanging that described another plays pin.
Described adjustable plate is provided with knob, and knob is connected with the adjustable plate rib-loop.
The utility model compared with prior art has simple in structure, the percent of call completed height of test contact, and easy to operate, safety, and can satisfy the test request of multiple function, the advantage that production cost is low.

Embodiment
Consult accompanying drawing 1～3, the utility model comprises base plate 3, plays needle stand 1,7, plays pin 5,6, plays needle stand 1 for vertically being provided with the rectangular block of several parallel needle trays 12, and one jiao of rectangular block is provided with the groove 13 that intersects vertically with needle tray 12; Playing needle stand 7 is a rectangular block, and its end face is provided with chute 16, the affixed adjustable plate 8 in side, is provided with the slide block 10 of several parallel needle trays 14 in the chute 16; Playing needle stand 1,7 is fixedly installed on the base plate 3 by screw 2 in twos relatively; Playing pin 5,6 is that several and parallel two rows are arranged in the needle tray 12,14, one end and base plate 3 welding; 3 times affixed plug sockets 4 of base plate.Slide block 10 is provided with long kidney-shaped hole 15, and is connected in the chute 16 by long kidney-shaped hole 15 by screw, and slide block 10 is slidingly connected 3 times affixed two plug sockets 4 of base plate with bullet needle stand 7 in chute 16. Needle tray 12,14 is darker elongate grooves, playing pin 5 is the elongated copper wire that an end is provided with flanging, play pin 6 and be provided with the elongated copper wire of flanging for two ends, playing pin 5,6 is phosphorus copper wire, and elasticity is bigger, it is stuck in the needle tray 12,14 that plays needle stand 1, slide block 10, its lower end is welded on the base plate 3, so both can make two to play pin 5,6 correct location and keep vertical, can avoid two 5,6 on pins of bullet to be short-circuited again, adjustable plate 8 is provided with knob 9, and knob 9 is connected with adjustable plate 8 rib-loops.
Consult accompanying drawing 4, the utility model is to use like this: artificial cochlea's electrode array union 11 is put into the centre that two rows play pin 5,6, make bullet pin 5,6 distinguish corresponding one by one contact with each contact on the pole matrix 11, adjusting knob 9 makes slide block 10 move to playing needle stand 1 direction, make two bullet pins 5,6 compress pole matrix 11, plug socket 4 connects different test base plates can carry out different electric performance tests to pole matrix 11.During test, each contact on the pole matrix 11 all with play pin 5,6 corresponding one by one contacts, guarantee the connection of test contact, detect each the contact switching line state on the pole matrix 11, whether well contact with judgement.
