Abstract
The utility model relates to a detachable probe of an otoacoustic emission detector. The detachable probe comprises a shell, two miniature earphones, a miniature microphone, a fixing block of the miniature earphones and the miniature microphone, a sound guide pipe and a probe sleeve suitable for all people, wherein the fixing block is arranged in the shell and is used for fixing the two miniature earphones and the miniature microphone; the sound guide pipe is integrally formed by three bending stainless steel pipes and plastic, and can be freely disconnected from and connected with the shell part; a wire is fixed and clamped by a wire fixing sleeve. According to the design, the earphones and the microphone are positioned through a positioning block, so that the process problem of difficulty in packaging of an original integrated probe is solved, replacement of internal elements and after-sales service are facilitated, and the cost is reduced; in addition, by the design of the steel pipe type sound guide pipe, the phenomenon of non-smoothness in inner bending holes of a plastic piece can be reduced, and the transmission smoothness of a sound signal is improved. Moreover, the whole sound guide pipe can be picked through rotation and can be frequently cleaned by a user so as to prevent non-smooth sound transmission caused by blocking of the sound guide pipe.
Description
Technical field
This utility model belongs to armarium technical field, is specifically related to the architecture advances of the detachable probe of a kind of otoacoustic emission instrument.This probe is used for recording otoacoustic emission signal.
Background technology
At present, the detachable probe of otoacoustic emission instrument that we use is all-plastic shell and acoustic conducting pipe, and internal phone and Mike are integrated colloid encapsulation, are not easy to change components and parts.Three sound penetrating holes of acoustic conducting pipe are bent hole, for overall dimensions is dwindled, very little of aperture, due to the limitation of plastic cement technique, hole inwall is understood unavoidably some burr and is difficult to remove, and can have influence on sound translative performance, and probe was used after a period of time in addition, acoustic conducting pipe need to be taken off cleaning, and winning of this structure neither be very convenient.
Summary of the invention
In order to overcome above shortcoming, the object of the present invention is to provide a kind of simple in structurely, probe is detachable, can realize quick cleaning acoustic conducting pipe, install and to change device convenient, and the otoacoustic emission instrument that can reach best sound conducting effect is detachably popped one's head in.
For achieving the above object, the technical solution adopted in the utility model is: this otoacoustic emission instrument is detachably popped one's head in, there is shell, earpieces, miniature Mike, fixed cover, transmitting probe and probe sheath, it is characterized in that: described fixed cover consists of silica gel and fixedly mounts in the enclosure, described earpieces and Mike are fixed in fixed cover, on fixed cover, there is corresponding earpieces and Mike's through hole, described transmitting probe adopts snap fit to be connected with shell, the acoustic conducting pipe of described transmitting probe is connected with through hole, described probe sheath is connected with acoustic conducting pipe assembly.
The acoustic conducting pipe of described transmitting probe adopts gapless stainless steel tube and plastic monoblock molding to form.
Described shell is two halves formula structure, and two halves button merga pass trip bolt is fixed.
Adopt the beneficial effect of technique scheme: the pair of right and left shell of the detachable probe of this otoacoustic emission instrument is fixed on fixed cover in shell, is fixed with earpieces and Mike in fixed cover, has changed the fixed form of original overall sealing.Described transmitting probe adopts snap fit to be connected with shell, the hole that during installation, transmitting probe can alignment housings end face is put into, and be rotated clockwise to and turn motionless, now three holes on transmitting probe are corresponding respectively with the hole of Mike, earphone, this clamps mode can Fast Installation and lay down acoustic conducting pipe assembly, very convenient to managing the cleaning of interior dirt, can effectively prevent the impact of tube hole plug on otoacoustic emission test, meet human engineering.Transmitting probe acoustic conducting pipe adopts gapless stainless steel tube and plastic monoblock molding to form, and steel pipe inner wall is smooth, is conducive to test the conduction of acoustical signal, can improve the stability of test signal.Compared with prior art, simple in structure, transmitting probe and shell are detachable, and easy cleaning is installed and changed device conveniently, and can reach best sound conducting effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, specific embodiments of the invention are described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is detachable probe scheme of installation.
The specific embodiment
As Fig. 1, 2, otoacoustic emission instrument shown in 3 is detachably popped one's head in, there is shell 1, earpieces 6, miniature Mike 2, fixed cover 5, transmitting probe 3 and probe sheath 7, described shell is two halves formula structure, two halves are fixed by trip bolt after fastening, described fixed cover consists of silica gel and fixedly mounts in the enclosure, described earpieces and Mike are fixed in fixed cover, on fixed cover, there is corresponding earpieces and Mike's through hole, described transmitting probe adopts snap fit to be connected with shell, the end that this snap fit structure is shell has the space that transmitting probe can be stretched, opening is provided with the breach that on transmitting probe, fixture block can pass through, the outer wall of transmitting probe has symmetrically arranged fixture block, during use, transmitting probe stretches in the space of shell, clamping rotates to an angle, now the acoustic conducting pipe of transmitting probe is connected with through hole.The acoustic conducting pipe of described transmitting probe adopts gapless stainless steel tube and plastic monoblock molding to form, and described probe sheath is connected with acoustic conducting pipe assembly, and probe sheath is the various models that are applicable to various crowds.In use, hole that can alignment housings end face is put into, and be rotated clockwise to and turn motionless, now three of acoustic conducting pipe holes are corresponding respectively with the hole of microphone/ear-headphone, during test, according to different crowd, install different probe sheath additional at acoustic conducting pipe front end, install rear connection signaling interface and just can test to main frame.
