DeVilbiss 525KS Oxygen Concentrator Analysis Report
Device Detection and Identification
The product shown in the examined visuals is an oxygen concentrator, a medical device that separates oxygen from ambient air to deliver high-concentration oxygen to the patient for respiratory support. The product is a stationary, home-use medical device with a vertically positioned black plastic casing, equipped with wheels for mobility.
Brand and Model Information
As a result of detailed visual analysis of the product and examination of the accompanying warranty certificate, the brand and model information have been definitively determined:
- Brand: DeVilbiss Healthcare
- Model: 525KS
- Model Verification: The “DeVilbiss Healthcare” logo and the inscription “5 LITER OXYGEN CONCENTRATOR” are clearly visible on the device’s front panel. Furthermore, the “525KS” designation is clearly written in the model line of the Warranty Certificate provided with the product. This information aligns with internet data; the 525KS is the brand’s standard 5-liter oxygen concentrator series.
- Manufacturer Information: According to the warranty certificate, the manufacturer is Germany-based “DeVilbiss Healthcare GMBH”.
Originality Assessment
Considering the product’s casing structure, the quality of the silkscreen printing, the conformity of warning icons to standards, branded labels, and the official warranty certificate containing the serial number matching the device, the product has been assessed as an original DeVilbiss product. The “Sapio Life” labeled tape on the top handle also suggests that the device has been processed by an authorized medical gas supplier or distributor.
Documents and Label Information
Among the visuals, the product’s Warranty Certificate is present. The following critical technical data and identification information have been obtained from this document and the labels on the device:
- Serial Number (Seri No): B212250017KS (Identified from the warranty certificate).
- Barcode No: 0885304000976
- Model Description: 5 Liter Oxygen Concentrator (Written on the panel).
- Revision Code: The panel label contains the code “525DD-331 Rev A”, which is likely the front panel label or part revision code.
- Power and Safety Values: Next to the circuit breaker switch, the inscription “3 AMP (Amperes)” is present.
- Warnings: It is stated that the device is sold “Rx Only” (By prescription only/with doctor’s advice).
Areas of Use and Function
This device is medical equipment that separates and concentrates oxygen from ambient air for patients suffering from chronic lung diseases (such as COPD) or respiratory failure, providing a continuous flow to the patient via a nasal cannula. It is suitable for use in home care services.
General Condition and State
The general condition of the device has been assessed as used. Detailed observations regarding its physical condition are as follows:
- Casing Integrity: No noticeable cracks, fractures, or major deformation have been detected on the black plastic outer casing. The casing integrity is preserved.
- Cosmetic Flaws: A white paper tape bearing “Sapio Life” is wrapped around the device’s carrying handle. Although it is unknown whether there is any damage beneath this tape, it generally appears to have been applied for inventory tracking or securing purposes. Slight dust accumulation is present on the device’s ventilation grilles and edges, indicating it has been used.
- Caster Wheels: Four wheels are located under the device, and they appear to be in place and sturdy.
Mechanical and Electronic Component Analysis
Based on the examination of the visuals, the outwardly visible condition of the mechanical and electronic components is as follows:
- Control Panel and Flowmeter: The flowmeter on the front face of the device is transparent and clean. The black ball inside is at the lowest level (0), which indicates that the device was off or no oxygen flow was present when the visual was taken. The gauge is scaled between 0 and 5 LPM (Liters/Minute).
- Switch and Buttons: The On/Off (I/0) switch appears to be intact. Immediately below it, there is a “RESET” labeled circuit breaker button, which is in a pressable state.
- Indicator Lights: The top panel features an LED panel area indicating the device’s operational status (Normal Oxygen, Low Oxygen, Service Required). Since the device was off, the active status of the lights could not be analyzed.
Accessories and Additional Equipment
The accessories attached to the device and identified in the visual are as follows:
- Humidifier Water Bottle: A transparent humidifier bottle with a black cap is present, placed in the special slot on the front of the device. Although the brand of the bottle cannot be fully read from the visual, “KIM…” or “NIM…” letters are discernible, but not 100% clear.
- Oxygen Cannula/Hose: A transparent oxygen hose connected to the humidifier bottle is present.
- Power Cable: A black electrical cable is seen hanging downwards from the side of the device.
- Quantity Information: The visuals show 1 main device with integrated accessories (bottle, hose) and 1 warranty certificate.
Potential Risks and Warnings
As a result of the visual analysis, no significant signs of malfunction requiring immediate intervention, such as breakage, burns, or cable damage, were found on the device. The product appears to be in “good” condition and suitable for use after maintenance. However, as it is a medical device, the fullness of the filter or the condition of the oxygen purity sensor cannot be determined visually, so an authorized service check and oxygen purity measurement are generally recommended and important for safety before use. The area under the tape on the handle can be checked for aesthetic purposes.
Manufacturing and Warranty Status
The warranty period specified in the document is “2 YEARS”. However, since the date fields in the document are covered by a stamp or unreadable in the visual, a definitive conclusion regarding the current warranty status cannot be made. Codes such as “525DD-331 Rev A” indicate that the device belongs to a specific revision series.
