Description
Technical field
This utility model belongs to clinical audition to be learned and rehabilitation audiology technical field, is specifically related to a kind of portable examination type of pocket sonometer of deafness patient being listened force estimation, diagnosis or Tingmin sensitivity test.
Background technology
The sonometer of present clinical use and audition examination equipment existing questions are: 1, volume is big, can only be placed in the fixed position and test, can not be when the doctor makes the rounds of the wards, go round visiting patients or use when seeing outpatient service; 2, existing sonometer local test signal has only the pure tone signal, does not have the speech test signal, and clinical adaptability is not strong, and testing efficiency is not high; 3, must in the audiometry sound booth, test,, influence precision of test result to avoid the interference of outside noise to the experimenter; 4, after existing sonometer test is finished, can not calculate test results such as average audition threshold value automatically.
The utility model content
It is a kind of easy to carry that the purpose of this utility model is to provide, and clinical adaptability is strong, and the testing efficiency height can calculate the portable examination type of the pocket sonometer of test result automatically.
For achieving the above object, the technical solution adopted in the utility model is: the portable examination type of a kind of pocket sonometer, comprise environmental noise automatic detection device, testing source, amplifier, audio frequency attenuator and output transducer, described environmental noise automatic detection device all is connected amplifier with testing source, and described amplifier, audio frequency attenuator and output transducer connect successively.
The beneficial effects of the utility model:
This device provides a great convenience for the user of audition screening, and 1, the user of service can place in the pocket, at any time the patient is tested, and do not need to select a quiet room as testing location.The test frequency is fixed when 2, carrying out pure tone test, clicks and selects; Also can select the speech test, built-in speech material is clicked to sound, and the sound intensity can pass through by key adjusting up and down, simple operation; 3, when test, can search for background noise automatically, and, draw result more accurately according to the automatic output intensity of revising various pure tones and speech test signal of the intensity of background noise; 4, also can select manual mode during test, revise test signal, guarantee that test result is accurately and reliably; 5, test result is preserved with the form of figure and form, also can directly connect computer by data wire, is convenient to the post-processed of data; 6, operator can average the calculating of audition threshold value as required, or calculate by other computing formula of setting; 7, can connect the direct printed report of printer.
Description of drawings
Fig. 1 is a theory diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model discloses the portable examination type of a kind of pocket sonometer.Comprise environmental noise automatic detection device, testing source, amplifier, audio frequency attenuator and output transducer, described environmental noise automatic detection device all is connected amplifier with testing source, and described amplifier, audio frequency attenuator and output transducer connect successively.Also comprise in addition above-mentioned each parts are started to control the embedded software of making usefulness, embedded software comprises:
A. user interface easily;
B. equipment room communications protocol and communication link;
C. patient information management;
D. hearing test algorithm;
E. automatic average threshold of audibility scheduling algorithm;
F. environmental noise autobalance algorithm;
G. speech audiometry source of sound and broadcast management;
H. detecting information data base.
Groundwork process of the present utility model is:
1. set kind, frequency, intensity and the transducer kind of current test signal by embedded software.
2. these being provided as parameter delivers to testing source and sends specification signal.
3. the environmental noise parameter that detects of specification signal that testing source is sent and environmental noise automatic detection device is calculated, and corrects the influence of environmental noise to test.
4. will deliver to low noise, low-power consumption, wide dynamic range amplifier through gauged test signal and amplify, and make signal amplitude arrive the requirement of software set.
5. the signal after will amplifying is sent into the high accuracy audio frequency attenuator, is superimposed with the correction zero level of specifying transducer.
6. the signal after will proofreading and correct is delivered to transducer and is sent test tone.
7. Ce Shi result is preserved by the test database of embedded software.
This device volume is gently little, both can carry out pure tone test, also can carry out speech audiometry, its method of testing and function meet GB/T16403 and GB/T17696 standard-required, test signal is provided with four frequencies such as 500Hz, 1000Hz, 2000Hz, 4000Hz, 6000Hz, and strength range 20---80dB is adjustable.Can compensate the output test signal according to the test environment noise sound, guarantee the test threshold result near the test result under the desired permission maximum noise of the GB/T16403-1996 environment, range of error can be controlled in the 10dBHL.The test environment noise compensation is provided with three gears, and the tester can regulate the compensation driving switch according to residing environment, when different gear is set, and the selected automatically output of test signal intensity compensation value.Adopt Color Liquid Crystal Display or LED screen apparent, frequency adopts right and left key to regulate, and intensity adopts key adjusting up and down.Test signal type: twiter sound and 6 speech sound.The configuration USB interface can be calibrated, the test signal type upgrades, and adopts ear inserting type earphone output test sound, adopts rechargeable type 1000mA lithium battery.Adopt miniature sound card and digital filter, digital equalizer etc. to set test frequency and intensity compensation.Can be used for carrying out the audition examination under the various environment such as audiometric room is interior, outpatient service, ward, sonifer center, school, factory.
This device provides a great convenience for the user of audition screening, and 1, the user of service can place in the pocket, at any time the patient is tested, and do not need to select a quiet room as testing location.The test frequency is fixed when 2, carrying out pure tone test, clicks and selects; Also can select the speech test, built-in speech material is clicked to sound, and the sound intensity can pass through by key adjusting up and down, simple operation; 3, when test, can search for background noise automatically, and, draw result more accurately according to the automatic output intensity of revising various pure tones and speech test signal of the intensity of background noise; 4, also can select manual mode during test, revise test signal, guarantee that test result is accurately and reliably; 5, test result is preserved with the form of figure and form, also can directly connect computer by data wire, is convenient to the post-processed of data; 6, operator can average the calculating of audition threshold value as required, or calculate by other computing formula of setting; 7, can connect the direct printed report of printer.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from this utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
