Intended Use

The Otoport Pro device is indicated for use when there is a requirement to screen for hearing disorders by objective and non-invasive means. ABR, TEOAE and DPOAE screening test results are automatically interpreted and a clear 'Pass' or 'Refer' result is presented to the user. Use of the device is indicated when the patient is unable to give reliable voluntary responses to sound, especially with infants. Use of the device facilitates the early detection of hearing loss and its characterization. Where the individual to be screened is healthy with no medical conditions related to the ear, as in the case of well-baby hearing screening, the user can be a trained screener. In all other cases the user should be an audiologist or medical professional. The TEOAE and DPOAE analytical functions of the device are indicated when objective non-invasive clinical investigations require the characterization and monitoring of the functional status of the peripheral auditory function. For this purpose, the device is intended to be used by audiologists or other professionals skilled in audiology. These TEOAE and DPOAE tests are applicable to populations of any age to obtain objective evidence of peripheral auditory function.

Device Story

Handheld device for objective hearing screening and diagnostic testing; records Otoacoustic Emissions (TEOAE, DPOAE) and Auditory Brainstem Responses (ABR). Inputs: acoustic stimuli via earphone probe; physiological signals via surface electrodes. Transforms inputs using signal processing (noise rejection, response enhancement) and statistical analysis to determine presence/absence of normal responses. Outputs: 'Pass'/'Refer' screening results or detailed graphical/numerical data for clinical review. Used in clinics/hospitals by audiologists, medical professionals, or trained screeners. Facilitates early detection of hearing loss; provides objective evidence of peripheral auditory function. Replaces previous modular design with integrated ABR/OAE functionality in a single handheld unit.

Clinical Evidence

Clinical comparison trial on adult volunteers (n=14-17 per modality) comparing Otoport Pro to predicate. Endpoints: Pass/Refer consistency and mean response level differences. TEOAE/DPOAE/AABR results showed high agreement; mean differences in TEOAE/DPOAE levels were <1dB and AABR amplitude differences were not statistically significant. Bench testing confirmed acoustic stimulus differences <0.4dB and response measurement differences <2dB.

Technological Characteristics

Handheld audiometer; Polylac PA-765 ABS enclosure. Stimulates via transient/tonal sounds (probe) and records via surface electrodes. Connectivity: USB-C (data/charging), Bluetooth 5.0. Power: 1000mAh Li-ion battery. Standards: ANSI/AAMI/IEC ES60601-1, IEC 60601-1-2 (EMC), IEC 62304 (software). Non-sterile. Integrated signal processing for noise rejection and statistical analysis.

Indications for Use

Indicated for hearing disorder screening and peripheral auditory function characterization in patients of any age (infants to adults). Used when voluntary response is unreliable. Contraindications: none stated.

Regulatory Classification

Identification

An audiometer or automated audiometer is an electroacoustic device that produces controlled levels of test tones and signals intended for use in conducting diagnostic hearing evaluations and assisting in the diagnosis of possible otologic disorders.

This predicate has not been the subject of any design-related recalls. ## DEVICE DESCRIPTION The Otodynamics Ltd ("Otodynamics") Otoport Pro device is a compact handheld device capable of high quality OAE measurements for clinical purposes and also automated ABR and OAE testing for fast infant screening. Responses to sound are recorded via an applied earphone and or adhesive surface electrode pad. Specifically, the device can record Otoacoustic Emissions (type DPOAEs or TEOAEs) and auditory brainstem responses (ABRs) to sound. These responses are especially useful in the hearing of infants for deafness. The more detailed analysis of DPOAE and TEOAE responses is additionally useful as a component of the audiological diagnostic test battery. The Otoport Pro is simple to use with customizable automation to make testing easy and the results clear. It has user access controls, graphical display panel, and extensive test database features. The Otoport Pro when configured for clinical use has advanced test features including extensive raw data capture for offline review and analysis if required. Otoport Pro device is a hardware/ software revision of the currently marketed Otoport OAE+ABR, having the same performance and intended uses as the Otoport OAE+ABR device. The previous version of the Otoport product (Otoport OAE+ABR) required an adaptor 'shell' to be fitted over the base unit if AABR functionality was required (Figure 1 below) In the Otoport Pro design (Figure 2 below) all test modalities are included inside the base unit. {4}------------------------------------------------ Image /page/4/Picture/0 description: The image shows a handheld Otodynamics device being held by two hands. The device has a screen at the top, followed by a series of buttons and a keypad. The keypad has numbers 1-9 and 0, along with other symbols. The device is white and has the brand name "Otodynamics" printed on it. Image /page/4/Figure/1 description: The image shows a handheld device with a screen displaying a graph labeled "DPZ TEST". The graph shows a red line fluctuating between -10 and 20 dBSPL across a frequency range of 2 to 8 kHz. Below the screen, there are several buttons, including a numeric keypad from 1 to 9, a 0 button, and other function buttons labeled "CANCEL", "MANUAL", and "END".
