QSCREEN is intended to be used in subjects of all ages. It is especially indicated for use in testing individuals for whom behavioral results are deemed unreliable.
Device Description
The QScreen is a hand-held and portable audiometric examination device offering test methods for the measurement of Otoacoustic Emissions (OAE) including transitory evoked otoacoustic emissions (TEOAE), distortion product otoacoustic emissions (DPOAE) and Auditory Evoked Responses like Auditory Brainstem Responses (ABR) in patients of all ages. It has a touch screen display and can be used with different accessories, such as its Docking Station, Ear Coupler Cable, Ear probe, Insert earphone, and Electrode cable. QScreen is a battery powered device which is charged by the Docking Station wirelessly and communicates with the Docking Station via Bluetooth. The Docking Station can be connected to a personal computer (PC) via USB cable on which patient and test data can be reviewed and managed with the optional software. Additionally, device and user profile configurations can be conducted with the software. Printing the data is also possible and carried out by a label printer that can be connected to the Docking Station. The QScreen device also contains a camera on the back side to read linear bar codes and QR codes. All materials that come into contact with human skin are selected to be biocompatible. The operating system on the QScreen is a self-contained firmware. The user is guided by the menu on the touch screen through the measurement. The results are evaluated on the base of signal statistics. The device offers an automatically created result, which can have the values "PASS" (Clear Response), "REFER" (No Clear Response) or "INCOMPLETE" (Test aborted).

No
The summary describes automated evaluation based on signal statistics and a simple "PASS", "REFER", or "INCOMPLETE" result, which does not indicate the use of AI/ML. There are no mentions of AI, ML, deep learning, training data, or complex algorithms typically associated with AI/ML.

No
Explanation: The device is described as a "hearing screener" intended for recording and automated evaluation of Otoacoustic Emissions (OAE) and Auditory Brainstem Responses (ABR). It is used for diagnosis and screening, not for treatment or therapy.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states that the QSCREEN device is a "hearing screener intended for recording and automated evaluation of Otoacoustic Emissions (OAE) and Auditory Brainstem Responses (ABR)." These tests are used to "obtain objective evidence of peripheral auditory function" and "peripheral and retro-cochlear auditory function," which are diagnostic purposes to identify potential hearing issues. The device evaluates results and provides "PASS", "REFER", or "INCOMPLETE" outputs, indicating its role in diagnosing or identifying a condition.

No

The device description explicitly states it is a hand-held and portable audiometric examination device with a touch screen display, battery power, and various physical accessories (Docking Station, Ear Coupler Cable, Ear probe, Insert earphone, Electrode cable). It also mentions hardware testing like electrical safety, EMC, mechanical, and acoustic testing. This indicates it is a hardware device containing software, not a software-only medical device.

Based on the provided information, the QSCREEN device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states that the device is for "recording and automated evaluation of Otoacoustic Emissions (OAE) and Auditory Brainstem Responses (ABR)." These are physiological responses measured from the patient.
  • Device Description: The device description details how it measures these responses using probes and electrodes placed in or on the body.
  • Evaluation of Results: The device performs an "automated evaluation" of the collected data, resulting in a "PASS," "REFER," or "INCOMPLETE" outcome. This evaluation is based on the physiological signals measured.

While the device itself is a medical device used to collect physiological data, the evaluation of that data to determine a "PASS" or "REFER" outcome based on the measured OAE and ABR signals falls under the scope of in vitro diagnostics. It's analyzing biological signals to provide information about a patient's health status (in this case, hearing function).

The fact that it doesn't involve analyzing samples like blood or urine doesn't preclude it from being an IVD. The definition of IVD includes devices used to examine specimens derived from the human body, and physiological signals like OAE and ABR can be considered a type of specimen derived from the body's function.

Therefore, the QSCREEN device, with its automated evaluation of physiological responses for diagnostic purposes, fits the definition of an In Vitro Diagnostic device.

Clinical Performance Data:

No clinical performance data was collected for the subject device QScreen. Substantial equivalence was shown through bench testing and compliance to international standards (IEC 60645-6:2009 (OAE) and IEC 60645-7:2009 (ABR)).

SUBSTANTIAL EQUIVALENCE

The QScreen device utilizes the same methods, stimulus parameters and accessories to evoke, record, process and detect ABR and OAE responses as implemented in the predicate Sentiero.

Bench testing was performed for relevant audiological characteristics of the stimulus delivered to the patient as well as interpretation of the recorded potential. These tests included frequency, timing and sound level of the stimulus as well as noise resistance and the lowest response signal detectable by the device. The results show the substantial equivalence of the subject device to the predicate device in terms of non-clinical performance.

Additionally, biocompatibility, electrical safety, and EMC testing was conducted by independent laboratories to demonstrate that the subject device is as safe and as effective as the predicate device.

The QScreen uses the same material and manufacturers for the housing, sockets, plugs, charger, display, PCB and the accessories as the predicate Sentiero device.

OVERALL CONCLUSION

The comparison between QScreen and the predicate Sentiero reveal comparable technical characteristics such as test parameters, recording techniques, and accessories. As the QScreen has a subset of the functionality of the Sentiero device, differences in the scope of testing and indications for use do not raise different question of safety or effectiveness.

The QScreen can be considered substantially equivalent to the predicate Sentiero in terms of technological aspects and indications for use.
