DeVilbiss 5 Liter Oxygen Concentrator Analysis Report

Device Identification and Basic Information

The product shown in the visuals is an electric oxygen concentrator used to provide respiratory support. The device’s brand and model information has been identified from the inscriptions on the front panel.

• Brand: DeVilbiss Healthcare
• Device Type: 5 Liter Oxygen Concentrator
• Quantity Information: 1 main unit and 1 humidifier water bottle

Applications

This device is designed to separate oxygen from ambient air and provide high-purity oxygen to the patient. It is suitable for use at home or in clinical settings for respiratory failure, COPD, or other medical conditions requiring supplemental oxygen support.

Physical Condition and State

The device is in used condition. No breaks, cracks, or deep scratches have been observed on its black outer plastic casing. There is noticeable dust accumulation and white residue deposits on the upper parts of the device, especially at the base of the slot where the humidifier bottle is placed. The carrying handle and the four wheels at the bottom appear to be intact.

Mechanical and Electronic Components

On the front right side of the device, there is a mechanical flow meter (rotameter) capable of measuring between 0 and 5 LPM (Liters/Minute) and an adjustment knob. Immediately to the left of the flow meter, there is a black main on/off (I/O) switch, and below it, a fuse (reset) button. There is no physical damage to the buttons.

The electronic indicators on the front panel are operational. The visual shows a green LED lamp with a checkmark and “O2” illuminated. This indicates that the device was operating and producing oxygen at a normal level at the time the photo was taken. The service (wrench) and low oxygen (down arrow O2) warning lights are not illuminated.

Screen Analysis and Usage Time

The device’s front panel features a digital LCD screen. To the right of the screen, there is an hourglass icon. The value 2846.3 is displayed on the screen. This value represents the device’s total operating hours.

Labels and Warnings

Various informational and warning labels are present on the device’s front panel and body.

• Technical Code: The code 525DD-331 Rev B b is written in small print on the bottom right corner of the front panel.
• Medical Symbols: The panel features the inscriptions MD (Medical Device) and Rx ONLY (Prescription Only) within a square.
• Safety Warnings: There are four circular pictograms indicating “No Smoking,” “Keep Away from Open Flame,” “Do Not Use Oil/Grease,” and “Read User Manual.”
• Service Label: An additional communication label has been affixed to the top of the device, displaying www.sapiolife.com.tr, 7/24 SUPPORT LINE, and (0212) 452 57 37.

Accessories

A humidifier water bottle with a brown cap and transparent body is attached to the front slot of the device. Traces of water or limescale are visible inside the bottle. A black power cable is seen emerging from the bottom left side of the device, with no visible crimping on the cable.

Potential Malfunction Risk

There are no breaks in the device’s outer casing or parts, and the green operating light is illuminated, indicating that the device is performing its basic functions. However, there is significant dust and residue accumulation on the device, particularly in the humidifier slot. This dustiness may indicate that the device’s filters are clogged. If not cleaned, risks such as obstructed airflow or overheating of internal components may arise.
