NIHON KOHDEN EEG System and Integrated Workstation Analysis Report

Device Detection and Identification

The examined image displays a comprehensive Electroencephalography (EEG) system, designed for medical diagnosis and neurological monitoring, mounted on a wheeled mobile workstation. The system is an integrated set consisting of a main data processing unit (PC), LCD monitor, amplifier (headbox), photic stimulator lamp, keyboard, mouse, and a dedicated trolley. The system shown is a professional medical device configured to record brain electrical activities in hospital and clinic environments.

Brand and Model Information

Brand and model information identified during a detailed examination of the image is as follows:

• Main System Brand: The NIHON KOHDEN logo and brand are clearly visible on the monitor frame, lower power unit, and interface boxes of the product.
• Computer Brand: The computer tower (Tower PC) located on the system’s shelf belongs to the DELL brand.
• Device Type: Based on the 10-20 electrode placement diagram on the amplifier and the general configuration, it has been confirmed that the device is an EEG (Electroencephalography) system.

Overall Condition and Originality

The product appears in the image to be in an extremely clean, well-maintained, and near-new condition. The printing quality of the NIHON KOHDEN brand logos, along with the color and material consistency of the components, confirms the device’s original manufacturing. No yellowing, wear, or color fading has been observed on the device; this image, appearing as if taken in a studio environment, suggests the device is cosmetically “flawless” or at a “refurbished” level.

Components and Mechanical Assembly Analysis

The mechanical and physical components of the system have been examined in detail:

• Trolley: A special medical trolley, white in color, made of metal and high-quality hard plastic. The shelves appear sturdy. There are a total of four wheels beneath the device, two of which have braking mechanisms, providing maneuverability. No signs of wear are visible on the wheels.
• Photic Stimulator Arm: A photic stimulation lamp (light stimulator) is located at the top of the monitor, attached to an articulated (movable) arm mechanism. The arm mechanism appears stable.
• Amplifier Stand and Arm: On the left side, there is a movable arm mounted on a vertical pole, which is height-adjustable (with a blue screw head) and supports the amplifier.
• Storage Bins: In the lower left section, there are two gray plastic waste or accessory bins. The bins are clean and sturdy.

Electronic Components and Screen Analysis

The visual condition of the electronic units is as follows:

• Monitor and Software: The LCD monitor is active and displaying the device’s software interface. Phrases such as “User: Patient”, “Data Monitor”, “Adult Examination”, “Neonate Respiration”, and menu buttons are visible on the screen. This indicates that the device’s operating system is running and the software is active. No dead pixels or cracks are visible on the screen surface.
• Computer Case (PC): A DELL brand computer in a horizontal case form (SFF or Desktop type) is present. Its front panel features a DVD-RW drive, USB ports, and audio inputs. There are no dents or scratches on the case.
• Power and Isolation Unit: The large white unit located on the trolley’s lowest shelf, featuring the NIHON KOHDEN logo and ventilation grilles, is likely the system’s isolation transformer and power distribution unit. Next to it are two smaller electronic modules/drivers.
• Amplifier (Headbox): The unit hanging on the left arm houses the electrode input sockets. Its front panel features an electrode placement diagram in the shape of a brain map and LED indicators. The buttons and plastic casing on it are sturdy.

Accessories and Connection Details

The accessories on the system are as follows:

• Keyboard and Mouse: A white wired keyboard and a black mouse, compatible with the PC, are present. The keyboard is on a dedicated shelf.
• Cabling: Most visible cables are concealed behind channels, with no dangling or messy cables in sight. The connection cable between the headbox and the main unit is spiral-shaped and robust.
• Missing Parts: The image does not show patient electrodes (leads), paste, caps, or other consumables required for EEG recording. The device represents a “ready-for-setup hardware” set, but the necessary consumable leads for patient application are not present in the image.

Areas of Use

This system is specifically designed for use in Neurology and Clinical Neurophysiology departments. Its primary uses include:

• Diagnosis and monitoring of epilepsy.
• Detection of brain function disorders.
• Investigation of sleep disorders (with Polysomnography support).
• Monitoring and recording of brain waves in adult and neonatal (referencing the “neonate” phrase on the screen) patients.

Potential Fault Risk and Conclusion Assessment

Based on the data obtained from the visuals, no signs of breakage, cracks, oxidation, or liquid contact were found in the physical condition of the device. There is no visible cable deformation or casing damage that would pose a “potential fault risk”. However, as the system is PC-based, the software license and calibration status should be checked before use. Visually, the device is immediately ready for use and in top-tier condition.
