Intended Use

The Fischer-Zoth Audiologic Systems model family "Echo-Screen T" consisting of Echo-screen T, Echo-Screen TA, Echo-Screen TD, Echo-Screen TDA and Echo-Screen TC are based upon Otoacoustic Emissions (OAE) and Auditory Brainstem Response (ABR) technology. The device is intended to screen hearing for newborns through adults, including geriatric patients. The device does not measure hearing per se, but helps to determine whether or not a hearing loss may be present. The "Echo-Screen T" product family consists of handheld, automated OAE and ABR based hearing screening systems which are easy to use. The measurement flow is menu guided and the evaluation is based upon signal statistics. The "Echo-Screen T" devices are intended to be used by trained personnel in a medical or school environment. The "Echo-Screen T" models are not intended for fitting assistive listening devices such as hearing aids or cochlear implants.

Device Description

The Fischer-Zoth Audiologic Systems model family 'Echo-Screen T' consisting of Echoscreen T. Echo-Screen TA. Echo-Screen TD. Echo-Screen TDA. Echo-Screen TC are based upon Otoacoustic Emissions (OAE) and Auditory Brainstem Response (ABR) technology.

AI/ML Overview

This appears to be a 510(k) summary for the Fischer-Zoth Echo-Screen T family of devices, seeking substantial equivalence to predicate devices. It describes the device's intended use and technological characteristics, but it does not contain specific acceptance criteria or study data demonstrating performance against such criteria.

The document states:

  • "The measurement flow is menu guided and the evaluation is based upon signal statistics." (Section 0)
  • "Signal statistical criterion for 'PASS' condition" (Section 1)

However, it does not provide details on:

  • What these "signal statistical criteria" are numerically (e.g., specific sensitivity, specificity, accuracy thresholds).
  • Any studies conducted to demonstrate the device's performance against these or any other clinical acceptance criteria.

Without this information, I cannot complete the requested tables and details about the study. The provided text focuses on the device's safety, electrical standards, and substantial equivalence to predicate devices, rather than a direct performance study to meet specific acceptance criteria.

Device description , intended Use & Effectiveness:

The Fischer-Zoth Audiologic Systems model family 'Echo-Screen T' consisting of Echoscreen T. Echo-Screen TA. Echo-Screen TD. Echo-Screen TDA. Echo-Screen TC are based upon Otoacoustic Emissions (OAE) and Auditory Brainstem Response (ABR) technology. Similar techniques and methods are - among others - used by the Fischer-Zoth model Echo-Screen and SLE Limited model SABRE.

The device is intended to screen hearing for newborns through adults, including geriatric patients. The device does not measure hearing per se, but helps to determine whether or not a hearing loss may be present.

The 'Echo-Screen T' product family are handheld, automated OAE- and ABR based hearing screening systems which are easy to be used. The measurement flow is menu guided and the evaluation is based upon signal statistics. They are intended to be used by trained personnel in a medical or school environment. The Echo-Screen T models are not intended for fitting assistive listening devices such as hearing aids or cochlea implants.

Technological Characterisitics: (also see Appendix B)

Automated stimulus adjustment and online control Signal statistical criterion for 'PASS' condition

Additional hints to measurement quality (stimulus stability and artefact rate) - Safety:

Battery powered, no connection to mains is possible during measurement Sound Pressure level: 70-85 dB SPL maximum

Current through electrodes limited to < 10uA maximum

Safety:

The 'Echo-Screen' Screening System is designed to provide electrical safety to the patient as well as the user. The system is designed to meet the following standards related electrical safety: IEC601-1, UL2601 and VDE750 (German MedGv).

The Echo-Screen T models are stand alone-system. They are battery powered with a 6V battery. During operation there are no connections to the mains.

During measurement there is a conductive connection to the patient via three Electrodes. The current through each single channel during the measurement is actively limited to < SuA.

To prevent excessive tone levels within the ear, the Echo-Screen T models are continuously controlling the level of the output tone or click-burst. The max. output level is controlled via software to 85dB SPL (sound pressure level) and the electronic hardware is build in such a way, that the speakers within the probe are incapable of producing enough decibels to permanently damage the ear.

The system will also be certified according to the following standards:

  • ISO 9001 Quality Management System
  • EN 60601 Safety
  • Class IIa device, disposable are Class I - EN 46001
  • Group 1 (inedical equipment, conducted and radiated emissions) - EN 55011
  • IEC801-3 Radiated Electromagnetic Field Susceptibility
  • CE Mark

Conforms the provisions of European council Directive 93/42EEC concerning medical devices.

Summary of Effectiveness:

The 'Echo-Screen T' models are portable OAE/ABR based screening systems. The aim is to detect and track hearing loss and abnormal middle ear conditions as early as possible in the person's life. Due to the automated test it easy to be used. by trained personal (nurses ... ) in a medical or school environment.
