Nihon Kohden Cardiolife TEC-5521K Defibrillator Analysis Report
Overview and Product Description
The device shown in the images is a Nihon Kohden Cardiolife brand TEC-5521K model defibrillator/monitor. The product is designed to deliver electric shocks to terminate abnormal heart rhythms (such as ventricular fibrillation and ventricular tachycardia) in medical emergencies. The device also functions as a monitor.
The quality of the logos, labels, and overall workmanship on the product indicates that the device is original. The images show one main unit and a pair of external shock paddles attached to the device, making a total of one device and its accessory.
Physical Condition and Deformations
The general condition of the device has been evaluated as used. Some signs of wear and cosmetic defects due to use have been observed. These defects include:
- On the device’s front panel, prominent cracks and yellowing are present on the white surface of the rotary knob used to adjust the shock energy level.
- On the blue section of the front panel, near the bottom left corner, there is a black stain or scuff mark.
- A general yellowing and soiling are observed in the color of the coiled cables connected to the defibrillator paddles.
- Various small scratches and stains, formed due to use, are present on the overall casing of the device.
Mechanical and Electronic Evaluation
In the mechanical components of the device, cracks in the energy selection knob are particularly noticeable. Other buttons and the paddle receptacles appear visually sound. The electronic components of the device are in working order; the images clearly show the screen is on and displaying data. No pixel errors or abnormal images have been detected on the screen.
Screen Analysis:
The device’s screen is active, and the following information can be read on it:
- Brand: NIHON KOHDEN
- Monitored Rhythm: VF/VT
- Shock Status: 0 J (Zero Joules, indicates uncharged state)
- Alarm Status: Alarm off (Alarm off)
- Time: 16:45
- A battery indicator is present on the screen.
Accessories and Technical Details
An integrated pair of defibrillator paddles is observed with the device. These paddles are connected to the main unit via coiled cables. No power cable, ECG electrodes, or other external accessories are present in the images. The only technical information visible on the device’s label is the model code.
- Model Code: TEC-5521K
Other label information such as serial number, lot number, or REF code are not readable in the images.
Malfunction Detection and Potential Risks
In the images, no malfunction message or broken part (excluding the knob crack) that would directly impede the device’s operation has been observed. The fact that the screen is working suggests that the basic electronic functions are active.
However, the most prominent potential malfunction risk in the device is the cracks in the energy selection knob. This knob is critically important for adjusting the shock level to be delivered to the patient. The cracks in the knob may grow over time, leading to the knob losing its function or breaking. This situation could pose a serious risk, such as the device being unusable during an emergency intervention. Apart from this defect, the overall condition of the device is at a level that can be considered normal for a used product.
