Product Analysis Report of Nihon Kohden Neurofax EEG Device

Basic Product Identification

• Device Identification: These images show the main unit and related accessories of an electroencephalography (EEG) system. The system consists of a monitor, keyboard, mouse, main computer unit, EEG sensors, and cables.
• Brand and Model:
  • Main Device: NIHON KOHDEN Neurofax
  • Accessory Device: NIHON KOHDEN LS-120 (labeled Flash Energy 1.25J)
  • Computer: HP Compaq (model information is not clearly readable)
  • EEG Electrodes: CNSAC EEG Cup Electrodes (REF CE-071c)
• Originality: The logos and labels on the product have a professional appearance. The overall workmanship quality seems high. Based on this, the products are considered original.
• Areas of Use: This system is designed for EEG, a medical device used to record brain electrical activity. It is used in fields such as neurology, sleep studies, and cardiology. The LS-120 accessory is likely a type of stimulator or calibration device. CNSAC EEG Cup Electrodes are disposable or reusable electrodes used in EEG measurements.
• Quantity Information:
  • EEG System (monitor, keyboard, mouse, main computer unit, EEG main module): 1 unit
  • NIHON KOHDEN LS-120 device: 1 unit
  • CNSAC EEG Cup Electrodes box: 2 units

Condition Assessment

The device is generally in good condition and appears to be a used product. There is superficial dust that requires cleaning. However, no serious physical deformation, crack, or breakage is observed. No damage or scratches are visible on the monitor screen. The keyboard and mouse are clean and usable. All cables are neatly coiled, and there is no visible damage to them.

• Physical Deformation: There are no significant scratches, dents, or cracks on the casing or other parts of the product. No discoloration has been observed.
• Mechanical Components: The wheels, shelving system, and overall structure of the device appear solid. Visually, no problems have been identified with the mechanical components.
• Accessories: The system includes a monitor, keyboard, mouse, numerous cables, and two boxes of EEG electrodes.
  • The electrode boxes are labeled REF: CE-071c, WIRE LENGTH: 150 cm (59″), QUANTITY: 10 PCS. The expiration date is stated as 2025-05. This date is likely the expiration date, and the products are still within their usable period.
  • The device has numerous socket inputs. These include external connection points such as “X1, X2, X3, X4, X5 RESP F, X6 RESP C, X7 RESP A” and numbered inputs for EEG electrodes (FP1, FP2, F7, F3, FZ, F4, F8, T3, C3, CZ, C4, T4, T5, P3, PZ, P4, T6, O1, O2, A1, A2). Additionally, “SpO2/CO2 DC1/DC2” sockets are present.
• Battery Status: No indicator or physical damage providing information about the internal or external battery status is detected in the images. It is not possible to comment on whether the computer unit is working or its battery life from the visuals.

Technical Information and Label Analysis

The labels on the device and screen visuals provide some important technical information.

• Label Information:
  • NIHON KOHDEN Neurofax module: Features function keys such as “SELECTOR(kΩ) 2 5 10 20 50” and “IMPEDANCE CHECK”. It also has numbered EEG inputs for “L” and “R” channels in different colors (green and blue) (FP1, FP2, F7, F3, FZ, F4, F8, T3, C3, CZ, C4, T4, T5, P3, PZ, P4, T6, O1, O2, A1, A2). On the upper part, “X1, X2, X3, X4, X5, X6, X7” external inputs are listed. The module also contains warning and information labels.
  • NIHON KOHDEN LS-120: Features the inscription “FLASH ENERGY 1.25J” and “SINGLE” and “POWER” buttons. This is likely a flash stimulator.
  • CNSAC EEG Cup Electrodes: Information such as REF CE-071c, WIRE LENGTH: 150 cm (59″), QUANTITY: 10 PCS, LOT number, manufacturing, and expiration dates are present on the boxes. The expiration date is stated as 2025-05.
• Screen Analysis: The monitor screen is off. No error messages, menus, or warnings are visible on the screen.

User and Warranty Information

• Size and Compatibility: The general dimensions of the device can be inferred from the visuals, but precise measurements or compatibility information for a specific user group (infant/child/adult) is not available. The size of the EEG electrodes and cable length are indicated on the boxes.
• Year of Manufacture: No label or document regarding the general manufacturing year of the device is found in the images. However, the 2025-05 date indicated on the electrode boxes suggests that these electrodes are relatively new or were manufactured recently.
• Documents: No documents such as invoices or warranty certificates are found in the images. Therefore, no information can be provided regarding whether the warranty is still valid.
• Usage Time: No information regarding the total usage hours or duration of the device is available on the screen or labels.

Malfunction and Risk Assessment

There is no clear evidence of the device being faulty (e.g., broken parts, error messages) in the images. The overall condition of the device appears good visually. No potential malfunction risks such as severe wear, rust, or crushed cables have been observed. The device gives the impression of being well-maintained and regularly used. Based on visual inspection, there are no apparent issues that would hinder the use of the product. It is important to note that potential risks are merely a foresight based on visual inspection and do not necessarily mean that a malfunction will definitively occur.
