No
The document describes a standard admittance meter with programmable functions for middle ear evaluation and acoustic reflex testing. There is no mention of AI, ML, or any related technologies in the intended use, device description, or performance studies. The focus is on traditional audiological measurements.
No
The device is described as an "Admittance Meter" used to evaluate middle ear functions and perform acoustic reflex tests. These functions are diagnostic in nature, aimed at identifying conditions rather than treating them.
Yes
The device evaluates various middle ear functions and performs acoustic reflex tests to identify conditions like otitis media, glue ear, and eardrum scar tissues, which falls under the definition of diagnostic purposes.
No
The device description explicitly states "ADMITTANCE METERS" and describes functions like performing tympanometry and acoustic reflex tests, which are inherently hardware-based measurements requiring physical interaction with the ear. The predicate device is also an "Admittance Meter," further indicating a hardware component.
Based on the provided information, the Amplaid A724 and A728 are not In Vitro Diagnostic (IVD) devices.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for diagnostic purposes.
- Device Function: The Amplaid A724 and A728 are described as "Programmable Admittance Meters" that evaluate middle ear functions and perform acoustic reflex tests. They do this by measuring acoustic impedance within the ear canal and middle ear.
- Method of Use: The device is used directly on the patient's ear (in vivo) to measure physical properties (acoustic impedance and reflexes). It does not involve the collection or analysis of specimens taken from the body.
Therefore, the Amplaid A724 and A728 fall under the category of medical devices but not specifically In Vitro Diagnostic devices. They are used for diagnostic purposes, but the diagnostic information is obtained through direct measurement of physiological responses and physical properties within the body, not through the analysis of biological samples.

§ 874.1090 Auditory impedance tester.
(a)
Identification. An auditory impedance tester is a device that is intended to change the air pressure in the external auditory canal and measure and graph the mobility characteristics of the tympanic membrane to evaluate the functional condition of the middle ear. The device is used to determine abnormalities in the mobility of the tympanic membrane due to stiffness, flaccidity, or the presence of fluid in the middle ear cavity. The device is also used to measure the acoustic reflex threshold from contractions of the stapedial muscle, to monitor healing of tympanic membrane grafts or stapedectomies, or to monitor followup treatment for inflammation of the middle ear.(b)
Classification. Class II (special controls). The device, when it is a tympanometer or auditory impedance tester that complies with FDA-recognized consensus standard ANSI S3.39, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 874.9.
