NIHON KOHDEN Cardiofax ECG Device Analysis Report

Device Identification, Brand and Model Information

The examined image displays a medical diagnostic device. Based on its physical structure, including the thermal printer compartment, electrode connection port icons, and screen layout, this is an ECG (Electrocardiography) device.

Based on the clear data obtained from the image, the device’s identification details are as follows:

• Brand: The NIHON KOHDEN logo and text, embossed onto the plastic casing in the upper left corner of the device, are clearly legible.
• Model: The designation Cardiofax is clearly visible on the left side of the device’s control panel, next to the logo and symbols. The device belongs to Nihon Kohden’s Cardiofax series. The specific numerical model code for the series (e.g., ECG-xxxx) is not legible due to the viewing angle in the image or a possible label covering, therefore only the series name is stated.

Areas of Use

This device is designed for use in medical units such as hospital cardiology outpatient clinics, emergency rooms, operating theaters, and primary healthcare centers. Its primary function is to detect the patient’s heart activity (electrical signals) via electrodes attached to the skin, then graphically print them on paper or display them on a screen. It is used in the diagnosis of heart rhythm disorders and heart diseases.

Authenticity Status

The quality of the brand embossing on the device’s plastic injection mold, the craftsmanship of the control panel “overlay” (keypad cover), color tones, and button arrangement precisely match Nihon Kohden’s design language. The details in the image indicate that the product is original.

Quantity Information

The image shows 1 unit of the main device (ECG machine). No external accessories (ECG cable, bulb, clips, etc.) or power cables are within the image frame.

Overall Condition and Cosmetic Inspection

The device is in used (second-hand) condition. Details regarding its condition are as follows:

• Casing Color and Deformation: The device’s plastic casing, likely originally light gray or white, exhibits noticeable yellowing, which can occur over time and due to UV light exposure. While the casing integrity appears preserved, dust accumulation is observed in the upper left ventilation grilles. No breaks, cracks, or dents have been detected.
• Cleanliness: Dirt and dust residues are present on the recessed surfaces of the device (especially in the upper grilles and around the edges of the printer cover). It requires detailed external cleaning.
• Information Concealment: On the device’s control panel, diagonally to the upper right of the brand logo, there is a white, rectangular digital censorship or a physical label covering. This area likely conceals an institution’s name or inventory number.

Screen and Control Panel Analysis

The device features an LCD screen for data monitoring. The control panel is built on a blue strip bearing the “Cardiofax” inscription.

• Screen: The screen is currently in the off position. No deep scratches, breaks, or cracks are visible on the screen glass or panel. The surface reflection is clean, but its operational status (whether there are pixel errors) cannot be determined from this image.
• Keypad: A membrane-type keypad is used. The keys include:
  • F1, F2, F3 function keys.
  • Gender selection buttons (Female/Male icons).
  • Start/Stop button (Distinct green color with a graphic symbol).
  • Power button and status LEDs (AC power and Battery indicators).
  • Paper feed and control buttons.
• The prints on the keys are not erased and are legible. No tears or punctures are visible.

Mechanical and Electronic Components

Technical observations based on image data:

• Printer Section: A thermal printer compartment is located on the left side of the device. The compartment cover is closed, but a pink/red checkered ECG thermal paper, irregularly torn and appearing somewhat old, hangs out of the paper exit slot. The presence of paper suggests that the printer mechanism was active during the device’s last use.
• Electronic Indicators: To the left of the “Cardiofax” inscription, there are symbols indicating the device’s electrical connection and battery charge status, along with LED slots. The lights are not illuminated as the device is currently off.

Potential Failure Risk

The cosmetic condition of the device indicates its age. Although there are no visible breaks or severe damage, the yellowing of the plastic casing suggests that the device has been exposed to sunlight or extensive use for a long time. In older medical devices, internal batteries (if not replaced) may lose performance over time. However, the device’s casing is sturdy, and its external physical condition does not pose a risk that would prevent its reuse.
