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 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 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.
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.
Here's a breakdown of the acceptance criteria and study information for the Otoport Pro device, based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
The document describes the performance of the Otoport Pro in comparison to its predicate device (Otoport OAE+ABR, K143395) rather than setting distinct acceptance criteria with specific threshold values. The primary acceptance criterion appears to be demonstrating substantial equivalence in performance to the predicate device.
| Test Modality & Metric | Acceptance Criteria (Implied: Substantial Equivalence to Predicate) | Reported Device Performance (Otoport Pro vs. Predicate) |
|---|---|---|
| Acoustic Stimulus Differences | Differences in amplitude and waveform of acoustic stimulus (TEOAE, DPOAE, AABR) when using the same probe. | TEOAE: |
§ 874.1050 Audiometer.
(a)
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.(b)
Classification. Class II. Except for the otoacoustic emission device, the device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter, if it is in compliance with American National Standard Institute S3.6-1996, “Specification for Audiometers,” and subject to the limitations in § 874.9.
