Artromot K4 CPM Device Analysis Report

Overview and Device Description

The product examined is a Continuous Passive Motion (CPM) device used for the rehabilitation of knee and hip joints. These devices are generally utilized in physiotherapy processes to accelerate the recovery period after orthopedic surgery, prevent joint stiffness, and regain range of motion. The images show one main device and one wired hand remote control connected to the device.

Brand and Model Information

A detailed examination of the images clearly shows the brand and model information on the base of the device and on the hand remote control. The brand of the product is Artromot, and the model is K4. This information has been confirmed in multiple images.

Physical Condition and Deformation Analysis

The general condition of the device is assessed as used, and there are significant signs of wear and tear due to intensive use.

• Plastic Components: There is visible yellowing and discoloration on the beige plastic main body and base of the device. This condition may indicate the age of the device or prolonged exposure to light. There is also general dirtiness and some small scratches on the surface.
• Pads and Fabrics: The most prominent deformation of the device is observed in the blue fabric pads that come into contact with the patient’s leg. There are numerous holes, tears, and unraveling on the surface of the pads. Particularly, the yellow sponge material inside the upper pad has emerged through these tears. The fabric colors have faded and generally appear dirty.
• Straps and Tapes: The white Velcro straps used to secure the leg appear worn, and additional fabric or tapes are wrapped around them. This situation suggests that the original fastening mechanisms may have lost their effectiveness.

Mechanical and Electronic Component Assessment

No breaks or cracks are observed in the adjustment levers, metal slide rails, and movable joints, which are considered mechanical components. Regarding electronic components, an image clearly shows the screen of the hand remote control connected to the device is operational. The screen displays numerical values such as “-1°” and “6°” and arrows indicating the direction of movement. This indicates that the basic electronic circuits and screen of the device are functional. There is no visible crushing or breakage in the spiral and power cables connected to the device.

Label and Code Information

The following information is present on a white label located on the base of the device:

• Model Information: ARTROMOT-K4
• Code/Number: 11843
• Barcode Number: 800015711843

Apart from this label, standard label information such as serial number (SN), REF code, or Lot number could not be identified in the images.

Accessory Status

Apart from one hand remote control and one power cable, which are necessary for the device’s operation and are connected to the device via cables, no other additional accessories (such as a carrying bag, user manual, extra pads, etc.) are visible in the images.

Current and Potential Risk Assessment

The most prominent current issue with the device is the severe wear and tear and tears on the leg support pads. This situation can negatively impact both user comfort and hygiene. The pads and worn fastening straps may need to be replaced. The yellowing of the plastic casing is an aesthetic flaw and does not directly affect the device’s operation. Although the electronic components of the device appear to be working, considering the intensive physical wear, it cannot be guaranteed that all functions are operating flawlessly based solely on the images. However, there is no clear evidence of a major malfunction, and the device appears to be in working condition given its current state.
