DeVilbiss 525KS Oxygen Concentrator Analysis Report

Overview and Device Description

The device shown in the images is a DeVilbiss 525KS model oxygen concentrator. This product is a medical device designed to provide a continuous supply of oxygen to the user by concentrating oxygen from the ambient air. The labels and logo on the device indicate that it is an original DeVilbiss brand product. The images show one oxygen concentrator and one humidifier bottle attached to the device.

Area of Use and Purpose

This device is designed for use in home or clinical settings for patients who require respiratory support. Its primary function is to separate nitrogen from the ambient air to produce oxygen with a purity of 93% (± 3%) and deliver it to the user at an adjustable flow rate (maximum 5 LPM). The humidifier bottle helps to increase patient comfort by reducing the drying effect of the supplied oxygen.

Physical Status and Condition Assessment

The overall condition of the device is assessed as used. No significant cracks, fractures, or major impact marks were observed on its casing. The black plastic casing has slight dust and superficial stains resulting from use. The device’s wheels and the handle on top appear to be solid, and no mechanical issues are noticeable.

• Casing: Generally in good condition, with no major deformations.
• Mechanical Components: The flow adjustment knob, power switch, and reset button on the front panel are physically in place and appear to be intact.
• Filter: The filter cover on the rear panel and the foam filter inside it are present. The cleanliness of the filter cannot be clearly determined from the visual inspection.

Accessories and Parts

The following accessories have been identified with the device in the images:

• Humidifier Bottle: There is one humidifier bottle attached to the front of the device, with the brand name read as “R-med”. Although there is an informational label on the bottle, its content is not fully legible.
• Power Cord: A fixed power cord is attached to the back of the device. There is a barcoded label on the cord.

The device features one metal connector for the oxygen outlet and a power cord inlet. No finding of any missing parts was detected in the images.

Label Information and Technical Details

The following technical information has been obtained from the labels on the device:

• Brand: DeVilbiss Healthcare
• Model (REF Code): 525KS
• GTIN: 00 8 85304 00097 6
• Electrical Ratings: 220 V – 230 V ~, 50 Hz, 1.95 A
• Classification: Class II Type B
• Origin: Assembled in the USA
• Serial Number: There is a serial number barcode on the rear label, but the numbers are not clearly legible.
• Service Label: On the back of the device, there is a service label from the “SAPIO Healthcare” company with the phrase “7/24 ASSISTENZA GUASTI” (24/7 Fault Support).

Potential Risk Assessment

The overall condition of the device appears to be good, and no obvious malfunction that would directly prevent its operation has been identified. However, a slight bend and pressure have been observed at the point where the power cord enters the device. This situation could potentially cause a weakening in the internal structure of the cord in the long term. This observation is a prediction based solely on visual inspection and does not indicate an existing fault or that a fault will definitely occur. It can be said that the device gives a well-maintained impression.
