Respirox 7F-5B Oxygen Concentrator Analysis Report

Overview and Device Description

The product shown in the images is the Respirox 7F-5B Oxygen Concentrator, a medical device that produces purified oxygen using ambient air. The device is designed for patients who require respiratory support. This report includes a detailed examination of the device based on the images and relies solely on visual evidence.

• Product Type: Oxygen Concentrator
• Quantity Information: The images show a total of three parts: 1 oxygen concentrator, 1 humidifier water bottle, and 1 power cable.
• Intended Use: The device separates nitrogen from ambient air to provide concentrated oxygen. Thanks to its flow meter, it delivers oxygen output in a quantity adjustable in liters per minute.

Brand and Model Information

The logo and text on the front surface of the device clearly confirm the product’s brand and model.

• Brand: Respirox
• Model: 7F-5B

Physical Condition and Deformation Analysis

The product is a used device, and its general condition has been evaluated through the images. There are no visible serious cracks or fractures on its casing or plastic components. However, some cosmetic defects resulting from prolonged use are present.

• Overall Condition: The general condition of the device is assessed as used.
• Color and Casing: A noticeable yellowing is observed on the device’s plastic casing, originally in cream or white tones, particularly on the upper parts and front panel. This condition typically occurs over time or due to exposure to sunlight.
• Scratches and Stains: On the left front surface of the device, there is a circular sticker mark below the “OXYGEN OUTLET” text. Small scratches and darkening due to light friction are present on the lower corners and edges of the casing. Generally, dust and dirt residues can be seen on the device’s surface.

Technical and Mechanical Assessment

The technical components and mechanical parts of the device have been visually inspected, and no significant malfunction has been detected.

• Control Panel: A digital screen and control buttons are located on the top part of the device. The screen is off, and no cracks or damage are visible on it. The panel includes “COUNTS (hours)” and “TIMING (minutes)” indicators, “+” and “-” buttons for time adjustment, a “POWER” button, and status indicator lights. The buttons appear to be physically in place.
• Flow Meter: The flow meter located on the front right side of the device allows for adjustment between 0 and 5 L/min (Liters/minute). Its glass tube and the ball inside appear intact. The adjustment knob is also in place.
• Oxygen Outlet: No deformation has been observed on the metal oxygen outlet port, labeled “OXYGEN OUTLET”.
• Electronic Components: No comment can be made about the electronic components from the visual evidence, apart from the attached power cable. However, there are no visible issues like burns or melting in the observable parts.

Accessories and Complementary Parts

The accessories visible with the device are listed below. It could not be determined whether any part is missing, as the original box contents are unknown.

• Humidifier Bottle: A transparent plastic humidifier water bottle with a black lid is attached to the front part of the device. There are no visible cracks or fractures on the bottle, but the writings inside are not fully legible.
• Power Cable: A black power cable is connected to the device. No crushing, cuts, or stripping are observed on the cable’s outer insulation.

Potential Risk Assessment

Based on visual inspection, no obvious damage (such as a broken casing, burn marks, crushed cable, etc.) posing an immediate malfunction risk has been detected on the device. Cosmetic defects such as yellowing of the product’s casing and small scratches may not pose a functional risk. However, it should be noted that components like internal filters, the compressor, and sensors of such medical devices require regular maintenance and replacement. Since the device’s operating hours information cannot be read from the screen, it is recommended that it be checked by an authorized technical service before safe use.
