Device Description
The EEG-1200A with JE-120A is a digital EEG based on a minimum of a 32-bit computer with a filing function. The device uses Windows Graphic User Interface, receives physiological signals (up to 256 channels with JE-120 electrode junction box) from patients and digitizes the signals, the application of the software reproduces the waveforms, The EEG-1200A with JE-120A consists of a main unit, electrode junction box (head box), PC Unit, Isolation Unit and System Programs. The electrode junction box, monitor, keyboard and mouse connect to the computer. The computer and control panel connect to the main unit. Components requiring AC power plug into the main unit's isolated power supply. The main unit plugs into a hospital grade AC power source. All components fit onto a portable cart. A stand is also available for the electrode junction box. Patient data is stored to hard drive or other commercially available digital storage media. Inputs for Sp02 and EtC02 are available.

K#050833

No
The summary describes a standard digital EEG system with data acquisition, digitization, and display capabilities. There is no mention of AI, ML, or related concepts in the intended use, device description, or performance studies.

No.
The device is intended for diagnosis and recording of physiological signals, not for treatment.

Yes

The "Intended Use / Indications for Use" section explicitly states that the device provides data that "may be used by the clinician in sleep disorders, epilepsies and other related disorders as an aid in diagnosis."

No

The device description explicitly lists multiple hardware components including a main unit, electrode junction box, PC Unit, and Isolation Unit, in addition to the software.

Based on the provided information, the EEG-1200A series Neurofax is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis. The EEG-1200A records and displays physiological signals directly from the patient's body (cerebral and extracerebral activity) using electrodes. It does not analyze samples taken from the body.
  • The intended use describes recording, measuring, and displaying activity for EEG and Sleep Studies. This is a direct measurement of electrical activity within the body, not an analysis of a biological sample.
  • The device description details the components for signal acquisition and processing from the patient. It doesn't mention any components for handling or analyzing biological specimens.

Therefore, the EEG-1200A series Neurofax falls under the category of a medical device that directly interacts with the patient to acquire physiological data, rather than an IVD device that analyzes samples from the patient.

5.0 Conclusions

The substantial equivalence of the Nihon Kohden EEG-1200A with JE-120A 256 channel amplifier was demonstrated by testing in compliance with the Design Control process. The intended use and technology of the Nihon Kohden EEG-1200A with JE-120A 256 channel amplifier is equivalent to the predicate device Nihon Kohden EEG-1200A cleared with JE-212A 196 channel amplifier. The JE-212 with optional accessories JE-215A, JE-216A, and JE-217A mini electrode junction boxes allow up to 192 channels of amplification in 64 channel increments. The JE-120A with optional accessories JE-225A, JE-227A, and JE-228A mini electrode junction boxes allow up to 256 channels of amplification in 64 channel increments. The JE-225, 226, and 227, Are the same technology as JE-215,216, and 217, the only difference is the input connector is a slightly different configuration. The addition of the JE-228 is what allows the JE-120A to have up to 256 channels. The EEG-1200A with JE-120A also has inputs for SpO2 and EtCo2 which is the same as the technology found in Nihon Kohden's JE-921A. Validation was performed to ensure no new questions of safety or effectiveness are raised.

Dear Mr. Geerdes:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
