Artromot K4 CPM Device Analysis Report

Product Overview

The product shown in the visuals is an Artromot brand K4 model CPM (Continuous Passive Motion) device. This device is typically used in the rehabilitation process after knee and hip joint surgeries to prevent joint stiffness and restore range of motion. The product in the visual consists of one main unit and one hand control.

Brand and Model Identification

The inscription “ARTROMOT-K4” is clearly visible on the blue labels located on the device. The “ARTROMOT” brand logo is also present on the hand control. This information definitively confirms that the product’s brand is Artromot and its model is K4.

General Condition and State

The general condition of the device is assessed as used. There is noticeable yellowing on the plastic main body, thought to be due to age or exposure to sunlight. However, no cracks, fractures, or severe impact marks are observed on the main body. The metal components are generally in good condition. The blue pads providing foot and leg support appear to have been heavily used.

Physical and Mechanical Deformation

• Plastic Components: The beige plastic casing of the device shows visible yellowing. This is an aesthetic flaw and not a deformation that would affect the device’s operation.
• Pads and Textile Components: The blue pads where the patient places their leg show wear, small holes, and discoloration. In some areas, white tape has been used, likely to prevent further wear. These pads may need to be replaced for hygiene and comfort.
• Mechanical Components: Visual inspection of the device’s moving metal arms, adjustment screws, and slide system revealed no rust or fractures. The mechanical parts appear functional.

Electronic Components and Screen Analysis

The device is controlled by a wired hand control. In one of the visuals, the hand control’s screen is seen to be operational, displaying values such as “-6°”. This indicates that the device’s electrical components are active and performing their basic functions. The “MENU”, “START”, “STOP” buttons and directional keys on the hand control are also physically in place. The control cable has a coiled structure, and no crushing or breakage has been observed.

Accessories and Label Information

The main accessory of the device, the hand control, is present and connected to the device. The power cable is also visible in the visuals. The white label on the front of the device contains the following information:

• Model: ARTROMOT K4
• Barcode and Code: The label includes a barcode and the number “11843” beneath it. This number is believed to be a serial number or an inventory code.

Potential Risk Assessment

Based on visual evidence, the most significant risk associated with the device is the worn textile pads. The deterioration of these pads may reduce comfort during use and could be unhygienic. As it is seen to be electronically functional, the risk of immediate malfunction is assessed as low. However, the yellowing in the plastic components might indicate that the material has become brittle over time, although there are no cracks or fractures related to this in the current visuals. The mechanical components of the device appear to be in good condition and generally have the potential to serve after proper maintenance.
