Intended Use
The AE-918P EEG Neuro Unit is an 8 channel EEG measuring unit that connects to a Nihon Kohden patient monitor and is intended to monitor brain function. The unit amplifies and analyzes EEG and displays the EEG waveform and the result of analysis on the patient monitor. The AE-918P EEG Neuro Unit includes the calculation of a set of quantitative measures intended to monitor and analyze the EEG waveform. These include quantitative EEG functions such as SEF, MDF, PPF, TP, CSA, DSA, %Theta, %Alpha, %Beta, %Gamma, Abs Delta, Abs Alpha, Abs Beta, and Abs Gamma. These quantitative EEG measures should always be interpreted in conjunction with review of the original EEG waveform. The aEEG functionality included in the AE-918P EEG Neuro Unit is intended to monitor the state of the brain. The device is intended for use by medical personnel in any location within a medical facility, physician's office, laboratory, clinic or nursing home under direct supervision of a medical professional.
Device Description
The AE-918P is an 8 channel digital Electroencephalography (EEG) that connects to a Nihon Kohden patient monitor. It receives EEG data from patients and digitizes the signals, the waveforms and analysis are displayed on a Nihon Kohden Patient Monitor. The AE-918P is contained in a small enclosure that contains the EEG amplifier and digital circuitry. This enclosure is mounted to the bottom of the patient monitor and connects to the patient monitor through the multilink cable.
More Information

No
The summary describes standard quantitative EEG analysis methods and does not mention AI, ML, or related concepts.

No
The device is described as an 8-channel EEG measuring unit intended to monitor brain function by amplifying and analyzing EEG waveforms and displaying the results. Its purpose is diagnostic or monitoring, not therapeutic.

Yes

The device amplifies and analyzes EEG, displays waveforms and analysis results, and calculates quantitative measures (SEF, MDF, etc.) intended to monitor and analyze brain function and the state of the brain. These functions are used for diagnostic purposes by medical personnel.

No

The device description explicitly states that the AE-918P is contained in a small enclosure that contains the EEG amplifier and digital circuitry, indicating it includes hardware components beyond just software.

Based on the provided information, the AE-918P EEG Neuro Unit is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the examination of specimens derived from the human body (such as blood, urine, or tissue) to provide information for diagnostic, monitoring, or compatibility purposes.
  • AE-918P Function: The AE-918P directly measures electrical activity from the brain (EEG) through electrodes placed on the patient's scalp. It amplifies, analyzes, and displays this physiological signal. It does not analyze specimens taken from the body.
  • Intended Use: The intended use clearly states it is for "monitoring brain function" and analyzing the "EEG waveform." This is a direct measurement of a physiological process, not an analysis of a biological specimen.

Therefore, the AE-918P EEG Neuro Unit falls under the category of a medical device that performs physiological monitoring, but it is not an IVD.

Device Description

Electroencephalography (EEG) is the recording of electrical activity along the scalp. EEG measures voltage fluctuations resulting from ionic current flows within the neurons of the brain. In clinical contexts, EEG refers to the recording of the brain's spontaneous electrical activity over a period of time, as recorded from multiple electrodes placed on the scalp.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The AE-918P was subjected to safety and performance testing procedures. The AE-918P has undergone validation and verification testing to ensure conformance to all design requirements. Additionally, the system has undergone comparison testing to ensure the substantial equivalence of the calculation and display of EEG trends. These tests verified that the device performed within specifications. No Clinical testing was required. Testing of the Nihon Kohden AE-918P Neuro Unit was performed in compliance with Nihon Kohden Corporation design control process. Testing to standards IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-26 was done. Electrodes used are the same as the predicate device and have been tested for biocompatibility according to ISO 10993-1.

Performance Testing

The AE-918P was subjected to safety and performance testing procedures. The AE-918P has undergone validation and verification testing to ensure conformance to all design requirements. Additionally, the system has undergone comparison testing to ensure the substantial equivalence of the calculation and display of EEG trends. These tests verified that the device performed within specifications.

No Clinical testing was required

Testing of the Nihon Kohden AE-918P Neuro Unit was performed in compliance with Nihon Kohden Corporation design control process. Testing to the following standards was done. (See Table 3):

Table 3 Medical Electrical Equipment

IEC 60601-2-26 Part 2-26: Particular Requirements for the safety of electroencephalograph 2002-11

Electrodes used as accessories with the device are the same as those of the predicate device and have previously been testing for biocompatibility for a surface contacting device of prolonged duration according to ISO 10993-1 Biological Evaluation of Medical Devices Part 1: Evaluation and Testing.

Conclusion:

Based on the comparison information in the technical comparison chart above and confirmed by verification/validation testing in compliance with the Design Control requirements, the AE-918P was shown to be equivalent in safety and effectiveness to the main predicate device EEG-1200A.

The intended use of AE-918P Neuro unit is different from the predicate (EEG-1200A, K080546) because it is a simplified version of the EEG-1200A. thus with a subset of the intended use. The AE-918 has only 8 channels of EEG and used mainly for monitoring brain activity on a patient monitor. The EEG-1200 has up to 256 channels of EEG and can also be used for monitoring brain activity but has additional intended uses such as sleep studies. The technology and materials of the AE-918 are the same as used in the EEG-1200A. The other differences are covered by other predicates as shown in Table 1.
