Description
This utility model relates to a kind of otoacoustic emission pickup head, and this probe has transmitting tube and pick up, is used for the examination of audition.
At present, the method of detection audition commonly used is to use the microphone device of a standard to give acoustical signal of those who are investigated, judge its audition size by the doctor by artificial observation those who are investigated's reaction then, this method accuracy is relatively poor, almost can't detect baby's audition.Recent medical findings shows, people's ear also has the ability of launching sound wave beyond having the ability of experiencing sound, this ability will become the most basic harmless and objective means of testing hearing clinically, use this achievement to carry out Audiometric key and provide a more satisfactory otoacoustic emission pickup head.
The purpose of this utility model provides a kind of otoacoustic emission pickup head, and the stimulation sound wave of this probe self-test in the future instrument is sent into ear drum membrane, and the otoacoustic emission ripple that cochlea is produced converts the signal of telecommunication to.And can reduce the interference of external noise.
The purpose of this utility model is realized by following technical proposals: a kind of otoacoustic emission pickup head, two test sound wave transmitting tubes and a pick up input pipe are equipped with in the front portion of this probing shell, described transmitting tube and input pipe are the isosceles triangle parallel arranged, its outer suit housing, be provided with a pick up in the described housing, be provided with pickup integrated circuit G in this pick up, this pickup rear portion is provided with integrated circuit external cable and external plug, this pickup front end is provided with pickup hole and sound attenuation hole, and described housing rear portion is provided with rear end cap.When this utility model uses described plug is electrically connected with test instrunment, and the sound wave transmitting tube is communicated with test instrunment, this utility model is put into by side person's external auditory meatus got final product then.
Compared with the prior art this utility model has simple in structurely, and noise level is low, wide dynamic range, the advantage that high frequency performance is good.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is end view of the present utility model (right view of Fig. 1)
Fig. 3 is pick up end view of the present utility model (Figure 1A-A cross section place)
Referring to Fig. 1 to Fig. 3, otoacoustic emission pickup head of the present utility model, the housing 3 that plastics are arranged, two test sound wave transmitting tubes 4 and a pick up input pipe 5 are equipped with in the front portion of described housing, the diameter design of this pipe is in 1 millimeter, described transmitting tube and input pipe are the isosceles triangle parallel arranged, its shooting property of overcoat housing 6, this housing can be a sponge product, also foam plastic product, have the cone profile, fill in during use in the external auditory meatus, the outside noise of can decaying (the shown section of Fig. 2 is a situation of having removed the elasticity housing).A pick up 2 is housed in the described housing, be provided with pickup integrated circuit G in this pick up, the model of the pickup integrated circuit of present embodiment is (GV202 3133), this pickup rear portion is provided with integrated circuit external cable 7 and external plug 9, by this plug this utility model is electrically connected with test instrunment, this pickup front end is provided with pickup hole 10 and sound attenuation hole 11, also be provided with the hole corresponding 12 on the described housing with this hole, after pick up is installed on the housing, hole 11 will connect into a duct that is communicated with hole 12.Described housing rear portion is provided with rear end cap 1, and this end cap is fixed on pick up in the housing.Article two, the test sound wave transmitting tube is fixed by injection molding way and housing, its anterior be the isosceles triangle parallel arranged with input pipe and be in the same place, its afterbody stretches out from lower part of frame, the flexible conduit 8 by rubber is communicated with the sonic generator of test instrunment.This utility model put into just can be carried out by side person's external auditory meatus that audition detects and examination.
