Nihon Kohden Cardiolife TEC-7621K Defibrillator Analysis Report

Device Identification and Product Description

The device shown in the examined images is a medical emergency response equipment, a defibrillator (electroshock) and patient monitor. The device is designed to be portable, featuring an integrated carrying handle and hard paddles, which are shock application electrodes.

Brand and Model Information

Upon detailed examination of the device’s front face and top panel, the following identification details have been definitively determined:

• Brand: The NIHON KOHDEN logo and text are clearly visible in the upper left corner of the device and above the screen.
• Series/Product Group: The inscription cardiolife, indicating the product family to which the device belongs, is located in the upper right corner of the screen.
• Model: The model number [TEC-7621K] is clearly stated on the label on the control panel on the right side of the device.

Authenticity Assessment

The print quality of the brand logos on the product, the industrial design language (beige casing, purple control panel, orange paddles), the placement of control buttons, and the alignment of labels indicate that the device is an original production of Nihon Kohden. There are no indications of aftermarket or copy production (e.g., incorrect fonts, poor quality plastic molding).

Areas of Use

The Nihon Kohden Cardiolife TEC-7621K is used to treat life-threatening cardiac rhythm disorders (such as ventricular fibrillation) by delivering an electrical shock to the patient to restore the heart to its normal rhythm. Furthermore, thanks to its screen and accessory inputs, it is also suitable for monitoring the patient’s ECG rhythm and heart rate. Emergency rooms, ambulances, intensive care units, hospital wards, and medical centers are its primary areas of use. The adjacent ECG cable accessory is required to utilize the device’s patient monitoring feature.

Quantity Information

In total, the images show:

• 1 unit of Nihon Kohden TEC-7621K Main Unit (with 2 integrated paddles).
• 1 package of external ECG cable (in a transparent bag).

General Condition and Cosmetic State

The device’s outer casing generally appears clean and well-preserved. The beige color of the plastic components has a reasonable appearance for its age, with no noticeable yellowing (due to excessive UV exposure). The device presents as a used medical device but gives a well-maintained impression.

Physical Deformation Examination

Upon a complete examination of the casing, no breaks, deep cracks, dents, or severe damage due to impact were detected on the body. Corners and edges remain solid. Plastic joints (hinge points or casing seams) are not separated and are neat.

Mechanical Component Condition

• Paddles: The orange shock paddles (Apex and Sternum) fit perfectly into their slots. No significant tearing or detachment is observed at the cable connection points (strain relief areas) on the paddles.
• Buttons and Selector Switch: The energy selection rotary switch (Selection Knob) on the right side is robust and in place. The prints on buttons such as “CHARGE/AED” and “SYNC” are not worn off and have not physically collapsed.
• Cable Coils: The coiled cables (spiral cables) leading to the paddles appear to have retained their elasticity, with no excessive sagging or tangling observed. Only slight dirt/dust is present on the cable surfaces.

Electronic Components and Screen Analysis

In the images, the device is in the off position. No deep scratches, cracks, or ink bleeding (indicative of an LCD break) were observed on the screen surface. The matte screen coating is intact. As the device is not connected to power and no visuals of it in operation are available, a definitive comment on the pixel status or electronic functionality (shock delivery capability) cannot be made based on the images.

Accessories

• Hard Paddles: Paddles suitable for adult/pediatric use (may be embedded) are mounted on the top part of the device. The left paddle is labeled “STERNUM”, and the right paddle is labeled “APEX”. Charge and discharge buttons are present on the paddles (Charge, Discharge buttons are visible in the image).
• ECG Cable: Next to the device, in a transparent bag, there is a gray ECG lead cable with multi-colored tips. This cable appears compatible with the “ECG” input socket located on the device’s lower left front face. The cable is clean and bagged, likely new or lightly used.

Battery Status

The device’s battery is embedded (internal) within the casing and is not directly visible from the outside. No leaked fluid, rust, or casing deformation due to battery swelling (especially in the lower parts) is observed on the battery cover or in the battery compartment area.

Labels and Technical Specifications

The labels on the device are legible. The detected technical details are as follows:

• Energy Levels: The energy selection knob shows energy levels ranging from 2 Joules to 360 Joules (2, 3, 5, 7, 10… 360(J)). This indicates that the device operates across a wide energy range (likely high energies suitable for biphasic technology).
• Warning Labels: Under the headings “DANGER” and “WARNING” on the top panel, there are English phrases indicating that it should not be used in environments with flammable anesthetic gases and that it should only be used by trained personnel.
• Usage Steps: Quick usage instructions marked with numbers 1, 2, 3 are present on the panel (1: Select Energy, 2: Charge, 3: Shock).

Potential Failure Risk and Assessment

As a result of the visual analysis, no critical damage (broken screen, detached cable, missing part) was detected on the device. As a potential risk, it is highly probable that the internal battery has reached the end of its life due to the device’s age (it is a consumable item in medical devices). Apart from the cleanliness of the coiled cables, no physical risk factor that would impede usage is present in the photographs. The cosmetic condition of the device can be categorized as “ready-to-use second-hand”.
