Oxygen Concentrator Analysis Report

General Assessment and Device Description

The product shown in the images is an oxygen concentrator used for medical purposes. The device is designed to meet the user’s respiratory needs by separating oxygen from ambient air. It comes with a humidifier water bottle and a flowmeter. The brand or model of the device could not be clearly identified from the inspection of the images. Therefore, brand and model information is not included in the report.

• Product Type: Oxygen Concentrator
• Quantity: 1 oxygen concentrator, 1 humidifier bottle, and 1 flowmeter.
• Area of Use: Used to provide medical oxygen for patients requiring respiratory support.
• Originality: While the general structure, labels, and screen of the device resemble a standard medical device, a definitive comment on its originality cannot be made due to the lack of brand information.

Usage Status and Physical Condition

The overall condition of the device is assessed as used. Yellowing, scratches, and stains on the body indicate that the product has been actively used before. Particularly, there is a noticeable discoloration (yellowing) on the beige plastic parts of the device’s top and front panels. Scratches caused by friction and some stains are observed on the lower and side parts of the body. No cracks or fractures were detected on the device.

• Overall Condition: Used.
• Discoloration: Noticeable yellowing is present on the plastic components of the device.
• Scratches and Stains: Scratches, friction marks, and dirt stains are present at various points on the device.
• Mechanical Components: The power button, timing adjustment buttons, and flowmeter valve appear physically intact. The humidifier reservoir on the front of the device is in place.

Screen Analysis and Usage Data

The blue-lit digital screen on the front panel of the device is operational and displays various usage data. This data provides important information about the device’s usage history. No pixel errors or damage have been observed on the screen.

• Screen Status: Operational and readable.
• Accumulated Time (Acc.Time): The screen displays that the device has been used for a total of 4149 hours.
• Start Times (S.Times): It is observed that the device has been turned on and off 1981 times.
• Operating Pressure (O.P. MPa): The screen indicates an instantaneous operating pressure of 0.164 MPa.
• Current Session Time (O.Time): It is read that the device has been operating for 2 minutes in the current session.

Technical Details and Accessories

The device features various technical components and accessories. The front panel includes the power button, control buttons for timing and backlight, status indicator lights, a flowmeter, and a humidifier bottle. No warranty certificate or invoice was found in the images.

• Indicator Lights: The green “P.O.” (Power) light, indicating the device is operating, is illuminated. Other warning lights (LO, HO2, HT, LP, HP, P.F.) are off.
• Accessories: A transparent humidifier water bottle and a flowmeter for adjusting the flow rate are present. No external cable or additional accessories are visible in the image.
• Label Information: An English “CAUTION” label is located on the right side of the screen. This label contains safety warnings such as reading the manual before use, changing the filter at regular intervals, having the device opened by professionals, and avoiding approaching with cigarettes or fire. No label containing a serial number or REF code was found on the device.
• Battery: There is no evidence of an external or internal battery in the image. It is understood that the device operates on mains electricity.

Fault Status and Potential Risks

There is no error code or illuminated fault warning light on the device’s screen. This indicates that the device is electronically performing its basic functions. No obvious physical fault (e.g., broken parts) has been observed.

The device’s total usage time of 4149 hours suggests that internal components (compressor, molecular sieves, etc.) may have a certain degree of wear and tear. Although there are no current signs of malfunction, it is recommended that such medical devices undergo periodic maintenance and have their filters replaced to maintain performance after high usage hours. The current condition of the device generally indicates that it is in working order.
