Technical field

The present invention relates to field of medical device, in particular to a kind of newborn hearing screening instrument.

Background technique

Audiometer is currently used medical instrument, has important role during detecting to human auditory, Especially newborn.Newborn hearing screening is to find the preferred means of congenital deafness, 24~36 generally after baby due Hour carries out, and is tentatively examined in the state of newborn's natural sleep or peace and quiet to its hearing by universal newborn hearing screening technical staff It looks into.

But usually neonatal external auditory canal with amniotic fluid, fat, tire saprolite the impurity such as is detained, earwaxes, and is leading to The entrance stimulating sound that can make otoacoustic emission and output-response signal dyingout are crossed in universal newborn hearing screening, causes percent of pass lower.It is existing Some disease screening instruments are checked after needing some months mostly again to confirm, this makes its parent on tenterhooks.

In order to more objective Precise Diagnosis hearing loss, it is necessary to it removes external auditory canal and earwaxes, and existing anti-clogging is set The standby suction that will be earwaxed by the way of drawing, but the preventing clogging up device drawn has large effect to neonatal ear-drum.

Summary of the invention

The technical problems to be solved by the present invention are: a kind of newborn hearing screening instrument is provided, when screening is unacceptable It waits, ear function is washed in automatic starting, and discharge is earwaxed and the impurity such as fat, improves the accuracy of screening.

The present invention solves the above problems used technical solution are as follows: a kind of newborn hearing screening instrument, including casing, institute It states casing to be fixed on a head-shield outside, the casing is equipped with left and right ear check mechanism, washes ear fluid storage box, exhausted bath box and control Device processed, the controller connect one or so ears and control motor, and the left and right ear control motor is connect with left and right ear testing agency, institute It states and washes ear fluid storage box and exhausted bath box is removably fixed on casing.

Preferably, described to wash the built-in urea peroxide solution of ear fluid storage box.

Preferably, the casing is equipped with indicator light, and the indicator light is connect with controller.In this way, indicator light can be used In the various states of display screening.

Preferably, a connecting band for fixing head is additionally provided on the head-shield.In this way, facilitating fixing head.

Preferably, left and right ear check mechanism includes that shell, cleaning cotton, the first conduit and cable, the shell include Top and bottom end, the cleaning cotton are coated on top, are equipped with gas cell in the shell, the cable is connected to by bottom end to be filled Air bag, the gas cell are connected to cleaning cotton by inflated hose, and first tube at one end, which is connected to, washes ear fluid storage box, separately One end is connected to inflated hose.In this way, will wash ear fluid by inflated hose is sprayed onto cleaning cotton, and it is easy to operate, convenient for cleaning.

Preferably, left and right ear check mechanism further includes the second conduit, and a suction air and an air-breathing are additionally provided in shell Hose, the cable are also connect with suction air, and the suction air is connected to cleaning cotton, second conduit one by inhaling hose End is connected to exhausted bath box, and the other end is connected to inhaling hose.In this way, the various impurity after cleaning are sucked out by inhaling hose, Neonatal ear will not be impacted, directly be excluded, it is easy to operate.

Preferably, a limited block is additionally provided on the shell.In this way, preventing from being excessively entering into neonatal ear, to new Raw youngster impacts.

Preferably, a sealing ring is additionally provided between cleaning cotton and the top.In this way, cleaning cotton can closely connect with top It connects, will not fall off.

Compared with the prior art, the advantages of the present invention are as follows: by setting left and right ear check mechanism checked when It waits, timely neonatal ear can be cleaned, screening state is being analyzed by indicator light, it is quasi- to improve screening Exactness；Gas cell suction air is set, timely waste liquid can be handled after cleaning.
