No
The summary describes a data acquisition system for EEG/PSG recordings and mentions standard signal processing and software validation, but there is no mention of AI or ML technologies.
No
The device is an electroencephalograph (EEG) intended to acquire, display, store, and archive electroencephalographic signals. This describes a diagnostic or monitoring function, not a therapeutic one which would involve treating or curing a condition.
Yes
The device, an electroencephalograph, is intended to acquire, display, store, and archive electroencephalographic signals for EEG or level 1-2 polysomnographic (PSG) recordings, which are diagnostic procedures.
No
The device description explicitly details hardware components including amplifiers, A/D converters, digital signal processors, storage devices, patient inputs, and connections, indicating it is a hardware device with accompanying software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is an electroencephalograph intended to acquire, display, store, and archive electroencephalographic signals for EEG or PSG recordings. This involves measuring electrical activity from the body (specifically the brain), not analyzing samples taken from the body (like blood, urine, or tissue).
- Device Description: The description details a data acquisition system with patient inputs for electrical signals (referential, DC, differential), pulse oximeter/photic input, and a patient event switch. This aligns with a device that measures physiological signals directly from the patient.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or any of the typical components or processes associated with in vitro diagnostics.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device measures electrical activity of the body.
