Description

A kind of medical earplug of 3D printing personalization anti-gas-leak

Technical field

The utility model relates to earplug technical fields, and in particular, to a kind of medical earplug of 3D printing personalization anti-gas-leak.

Background technique

The statistical communique issued according to World Health Organization: the whole world about 3.6 hundred million people suffer from disabling hearing loss at present, account for The 5% of population in the world total amount.Investigating to summarize to discuss with otopathy in national dysaudia would indicate that, China has 15.84% people to suffer from There is dysaudia, wherein not including recoverable otological disease.In daily otology outpatient service, often need to carry out the trouble of hearing test Person is more and more, just becomes more and more important for improving testing efficiency in checking.During conventional hearing test, selection is closed Suitable earplug is the prerequisite for improving test speed and result accuracy rate, and the airtightness of earplug is smooth in test process The most important thing of test is completed, therefore, suitable, good leak tightness earplug is selected to be particularly important in testing.Routine is listened The earplug of power inspection apparatus only has fixed several models, is not appropriate for all external ear road shapes for checking groups, for it is too big, Too small or lopsided external auditory canal, can not find therewith can be with relatively closed earplug.Further, since children have a lively disposition it is active, It is easy to cause earplug to fall off, influences the speed and accuracy of test；In out-patient, part aged, due to external auditory canal Fat is less, often has earplug to be not easy closed and leak air in test process, and since earplug is not enough bonded out with external auditory canal Existing discomfort；In addition to this, many patient's external auditory canals have fungal infection, if after such patient tests, to existing ear The disinfection of plug is not thorough, then is easy to generate cross-infection；In addition, existing earplug after patient checks, needs ability after disinfection It can be used to next bit patient, then, frequent and essential disinfection is easy to accelerate the aging of earplug and must stop making With one new earplug of replacement.With the continuous improvement of national healthcare level and living standards of the people, east that people use itself West requires higher and higher, more and more private, personalization, so that the application of the medical earplug of 3D printing personalization anti-gas-leak becomes It is more urgent.

Utility model content

A kind of in order to overcome the deficiencies of the prior art, the utility model provides medical ear of 3D printing personalization anti-gas-leak Plug, by modern 3D printing technique, customization meets personal external auditory canal and hearing test instrument is spoken soft earplug that hole matches. The earplug is consistent with external ear road shape using soft material preparation, can be closely bonded with external auditory canal and be easy to fixed, no It is easy gas leakage, slides, the time of suitable earplug is worn in selection when reducing mechanical stimulus and test；Since this earplug is personalized fixed System, so the case where preventing tester's mutual cross-infection, also reduces the time for needing to sterilize when test；The earplug is borrowed Help 3D printing technique to print according to ear canal shapes and hearing test instrument hole shape of speaking, can precision-matched external auditory canal, increase Add comfort.

The technical solution of the utility model is as follows: a kind of medical earplug of 3D printing personalization anti-gas-leak, including soft shell, The soft shell is printed according to patient's ear canal shapes and size using 3D technology, is and the matched ear canal shape of ear canal；It is described The front end of soft shell is towards in ear, and rear end is internally provided with the vent cap of perforation front-end and back-end towards outside ear, described Open inner of the vent cap in the front end and the rear end is equipped with the cylindricality plug through front and back end ports；The cylindricality plug The interior post holes for being equipped with perforation, the opening of the post holes match with the duct of speaking of hearing test instrument.

Preferably, being coated with antimicrobial nano stratum granulosum on the soft housing exterior walls.

The utility model has the following beneficial effects: the medical earplug of 3D printing personalization anti-gas-leak, meets human body difference ear Road shape, precision are close to external auditory canal without generating mechanical stimulus, prevent from falling off, and can be suitable for any hearing test crowd, solution The normal gas leakage of conventional earplugs of having determined and improper group；Soft material prevents damage external auditory canal close in test process without influencing The problem of closing property；It also solves the problems, such as earplug accelerated ageing and expensive due to frequent sterilization simultaneously, and increases earplug Service life；And it effectively solves the problems, such as to lead to cross-infection external auditory canal because disinfection is not in place.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the medical earplug of 3D printing personalization anti-gas-leak described in the utility model.

Specific embodiment

In order to make the purpose of utility model of the utility model, technical solution and technical effect are more clearly understood, tie below Specific embodiment is closed to be described further the utility model.It should be understood that specific embodiment described herein, be only used for It explains the utility model, is not used to limit the utility model.

Referring to Fig.1, a kind of medical earplug of 3D printing personalization anti-gas-leak, including soft shell 2, soft 2 foundation of shell Patient's ear canal shapes and size are printed using 3D technology, are and the matched ear canal shape of ear canal.The front end of the soft shell 2 1 is towards in ear, and rear end 3 is internally provided with the vent cap 4 of perforation front-end and back-end, the vent cap 4 exists towards outside ear The cylindricality plug 6 through front and back end opening is equipped in the opening 5 of the front end 1 and the rear end 3；In the cylindricality plug 6 Post holes 7 equipped with perforation, the opening 8 of the 7 cylindricality plug of post holes and the duct of speaking of hearing test instrument match, and having prevents The effect of gas leakage.

The 3D printing personalization anti-gas-leak earplug only includes a soft shell and one is spoken with hearing test instrument The cylindricality plug for the 3D printing that hole matches, prevents gas leakage, is easy to be tested.Since this earplug needs to customize, 3D printing is utilized The personalized equipment of technology customization, avoids the risk of tester's cross-infection.

It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field For personnel, without departing from the concept of the premise utility, architectural form cans be flexible and changeable, and can be produced with subseries Product.Several simple deduction or replace are only made, it is true by the claims submitted all to shall be regarded as belonging to the utility model Fixed scope of patent protection.
