Otoacoustic emission hearing screening instrument for children

1. It has both TEOAE and DPOAE test functions

Stimulation level: (DPOAE) 50-65 dB SPL

Stimulation type: Click (nonlinear) (TEOAE) 60~80dB SPL

Frequency range: (DPOAE) 2kHz, 3kHz, 4kHz, 5kHz

                             (TEOAE) 1.5KHz, 2KHz, 2.5KHz, 3KHz, 3.5KHz, 4KHz

Signal-to-noise ratio: (DPOAE) 6dB

                                  (TEOAE) 4 db 

Test passed 3 or more of 4 frequencies: (DPOAE)

                                                                (TEOAE) 3 or more of the 6 frequencies

Display: test process, environmental noise, test frequency, signal to noise ratio intensity 

The results were as follows: PASS/REFER

Test mode: routine mode and rapid screening mode. 

2. Display: ≥2.4 inch TFT color display, clear and intuitive color liquid crystal display, directly display the test results

3. User input: key operation, simple and easy to operate (up, down, left, right, confirm)

4. Built-in storage: ≥50 subjects, ≥200 test results

5. Built-in battery: continuous use for 8 hours (based on the standard use, actual use or affect the battery service time), using 4200mA large capacity lithium polymer battery 

6. Optional: data communication with the medical system, three docking modes are optional, supporting HL7 protocol docking, XML file docking, database docking, easy to connect with the medical system information, upload test reports. Patient data can be obtained directly for test data selection of subjects. 

7. Data transmission: charging and data transmission share, more convenient operation. The USB2.0 interface is used to connect the PC to read and temporarily store the report. The test report can be matched to the subject at any time and can be viewed and printed. The special communication data line is used. 

8. After connecting to the host, the test information in the cache device can be saved to the PC, and the subject information can be matched, and the report can be printed or uploaded. The report can display the noise, SNR, and judgment results. The chart can be displayed as a bar chart or a line chart. 

9. Printer: Bluetooth printer is used to achieve fast printing without matching. 

10. Language: Chinese operation interface, English optional.

11. Strong anti-interference ability, in the outpatient, office and ward can also be hearing test, obtain reliable data 

12 probe: ergonomic is not easy to fall off, easy to disinfect and clean. Adopt high precision acoustic microphone and high sensitivity acoustic and electric sensor. adapter

13. Earplugs: Silicone earplugs of various sizes 

14. Built-in calibration cavity, easy to calibrate at any time.
