DeVilbiss 525KS Oxygen Concentrator Analysis Report

Device Identification and Brand/Model Verification

The device shown in the images is an oxygen concentrator for medical use. The “DeVilbiss 5 LITER OXYGEN CONCENTRATOR” inscription on the front of the device and the information on the rear label clearly confirm that the brand of the product is DeVilbiss and the model is 525KS. On the upper rear part of the device, there is another label with the “SABIO” brand, likely belonging to a distributor or technical service company, but this does not change the original manufacturer of the device. Based on the quality of the logos and labels, the product is assessed to be genuine.

Intended Use and Quantity Information

This device is a respiratory apparatus that separates nitrogen from ambient air to produce concentrated oxygen, providing a continuous oxygen flow to patients in need of respiratory support. The images show 1 DeVilbiss 525KS Oxygen Concentrator and 1 humidifier bottle attached to the device. Other medical consumables visible in the background have been excluded from this analysis.

General State and Condition Assessment

The overall state of the device is assessed as used. Minor scratches and scuff marks, considered normal for its use, have been observed on its plastic casing and wheels. Nevertheless, the overall condition of the device is quite good. There is no significant fading in its color, nor any serious deformation such as cracks or breaks in the casing. It is apparent that the device has been generally cleaned and is well-maintained.

Physical and Mechanical Condition

The physical and mechanical components of the device have been examined in detail:

• Casing: The main black casing has no serious damage. There are only minor scuff marks on the lower parts and corners.
• Wheels: All four wheels are in place and do not show any breaks or deformations that would impede mobility.
• Controls: The power switch and the flowmeter knob for adjusting the flow rate on the front panel are physically in sound condition.
• Humidifier Bottle: The humidifier bottle at the front of the device appears transparent and clean. The “MAXIMUM” and “MINIMUM” water level indicators on it are clear.
• Air Filters and Vents: The ventilation grilles at the rear of the device are clear and clean. No blockages or damage are visible.

Accessories and Connection Ports

The only accessory visible with the device is the humidifier bottle attached to the oxygen outlet. At the lower rear of the device, the power cord and socket for connecting to the mains electricity are located. No crushing or wear has been observed on the outer insulation of the cord. The oxygen outlet port and the humidifier connection points appear to be in good order.

Label Information and Technical Details

The following technical information can be read from the manufacturer’s label located on the rear of the device:

• Brand: DeVilbiss Healthcare

Potential Malfunction Risk

In the examination based on the images, no obvious malfunction or damage that would directly affect the device’s operation has been identified. The minor scratches on the casing are purely cosmetic and do not pose a functional risk. The power cord and connection points appear to be sound. The overall good condition of the device suggests that it may have received regular maintenance. These observations indicate a low risk of mechanical or electronic malfunction. However, this assessment is a forecast based solely on visual evidence and is not a guarantee that the device is fully functional.
