Intended Use

The Interacoustics EP15 ABR Stand Alone Unit is a diagnostic tool for computer-based testing. Data is collected in a Windows 95,98 database format that allows for easy inspection of results. The EP15 Stand Alone Unit produces a sound stimulus for use in evoked response measurements or electroencephalogram activation.

Device Story

The Interacoustics EP15 ABR is a diagnostic system for evoked response auditory measurements; it functions as a computer-based stimulator and data collector. The device generates sound stimuli (clicks, tone bursts, various envelope shapes) delivered via transducers (e.g., insert phones) to the patient. It records electroencephalogram (EEG) signals through a 2-channel amplifier system. The system operates on a Windows 95/98 platform, allowing clinicians to inspect, store, and manage waveform data in a database. It features programmable stimulus parameters (frequency, intensity, rate) and signal processing filters (FIR filters). The device is used in clinical settings by healthcare professionals to assess auditory function. The output, presented on an industrial TFT display, assists clinicians in diagnosing auditory conditions by analyzing evoked potential waveforms. The system includes safety features like optical isolation and a built-in isolation transformer.

Clinical Evidence

No clinical data provided; bench testing only. The device's safety and effectiveness were established through compliance with performance and safety standards including VDE750, EN 60601-1 (General Safety), EN 60601-1-1 (Safety of Systems), EN 60601-1-2 (EMC), EN 60601-2-26 (Electroencephalographs), and EN 60645-3 (Auditory test signals).

Technological Characteristics
