FUKUDA DENSHI CARDIMAX FX-121 Electrocardiograph Device Analysis Report

Brand, Model, and Device Identification

As a result of the visual analysis, the main device displayed was identified as an electrocardiography (ECG) device. Based on the markings on the device’s front panel and user manual, its brand was confirmed to be FUKUDA DENSHI, its product series CARDIMAX, and its model FX-121. The device was observed to be a portable, compact model with an integrated handle and a built-in printer.

Visual Condition and Physical State

The device casing is a typical medical device beige/cream color. However, there is a noticeable color change (yellowing) on the device’s top cover and plastic surfaces around the keypad, which has occurred over time. A tonal difference is evident between the lower part of the casing and the top cover where the paper tray is located; this indicates that the device has been exposed to light for a certain period or has experienced material aging due to its age of use.

The front panel, keypad, and indicator LEDs are in a clean condition. No wear such as fading or illegibility is observed on the buttons. Mechanically, the paper tray cover or roll was viewed in an open/empty position. No prominent deep scratches, cracks, or breaks were detected on the outer casing.

Technical Details and Front Panel Analysis

A detailed examination of the device’s front control panel revealed the following technical function buttons and indicators:

• Lead Indicators (LED): LED lights marked STD, I, II, III, aVR, aVL, aVF, V1, V2, V3, V4, V5, V6 are present, indicating that the device can perform standard 12-lead ECGs.
• Sensitivity Adjustment: Indicators with 1/2, 1, 2 options and an adjustment button are present.
• Speed and Filter Buttons: Buttons with symbols for paper feed speed or filtering are visible.
• Calibration and Control: A “1mV” button is present for providing a calibration signal. Additionally, there are buttons for paper feed (indicated by an arrow), centering (reset), and Start/Stop (green button).

Accessories and Ancillary Products

Numerous accessories are provided with the device in the visuals. These accessories include:

• Patient Cable: A thick gray main cable connected to the main unit and a patient connection set with multiple leads at its end are present. The model number “CP-10J” and the “FUKUDA” logo are clearly visible on the splitter part of the cable.
• Limb (Clip) Electrodes: Green, clip-type electrodes are visible in the visuals. In one visual, these items are shown as 2 units in a foam slot, and in another, next to a green box (with TE-38 and Japanese characters, translated as “TE-38 Clip Electrodes” according to the visual’s English text).
• Chest (Suction) Electrodes: Among the cable harness, vacuum-type (suction type) metal electrodes with green rubber bulbs are present. A separate small green box contains the inscription “SUCTION TYPE CHEST ELECTRODE”.
• Power Cable: A gray power cable, used for the device’s mains connection, with a standard European type (Schuko-like) plug at its end, is present.
• Grounding Cable: Inside the accessory box, a yellow-green external grounding (equipotential) cable with a clamp at one end is found.
• Thermal Paper: At least 3 rolls of thermal printer paper (with a perforated core), packaged or in transparent wrapping, are visible.

Documents and Label Information

The set includes printed materials, understood to be original, related to the device’s use:

• Operation Manual: A yellow-covered English booklet titled “ELECTROCARDIOGRAPH CARDIMAX FX-121 OPERATION MANUAL” is present. The inscription “FUKUDA DENSHI CO., LTD.” is located on the manual.
• Accessory Boxes: Original cardboard boxes for some of the accessories are present (the box coded TE-38 and the Chest electrode box).

Originality and General Assessment

The compatibility of the device and its accompanying accessories (user manual, logos on the cable, electrode boxes) indicates that the product is an original FUKUDA DENSHI set. The device visually maintains its integrity. Although a clear label date for the manufacturing year is not legible, considering the device’s design, accessory codes such as “CP-10J,” and plastic yellowing, it is understood to be an older production. No active screen display or output indicating the device is operational is found in the visuals; therefore, no comment can be made about its electronic functionality, but physically it appears to be a complete set (device + all cables + electrodes + manual + paper).
