Detailed Analysis Report of Oxygen Concentrator

Device Identification

The device in the examined images is an Oxygen Concentrator used for medical purposes, which separates oxygen from ambient air and provides high-purity oxygen to the patient. The device is a vertical, wheeled (understood from the body structure), home-use, stationary medical device.

Brand and Model Information

Detailed examinations of the images revealed no writing directly indicating a specific globally recognized manufacturer brand (such as Philips, ResMed, Devilbiss, etc.) on the device’s front face or panel. The phrase “OXYGEN CONCENTRATOR” is located on the circular logo in the lower right corner of the device and around the logo. This phrase is a general description of the product rather than a brand. The product, due to its physical casing structure (beige top and bottom covers, gray middle body), has a design known in the market by model codes “7F-3” or “7F-5”; however, since the model number label is not clearly visible on the device, a definitive model name has not been specified.

Originality Status

The device, by its general design and label structure, appears to be a standard imported oxygen concentrator (generally of Far Eastern origin) commonly found in the market. The font and alignment of the English warning texts on the front panel are consistent with the standard format for such devices. There is no distinct finding suggesting the device is fake or a replica; it gives the impression of a product manufactured to industrial standards.

Areas of Use

This device is designed for patients suffering from respiratory failure such as COPD, asthma, and pulmonary fibrosis to receive long-term oxygen therapy (LTOT) at home. It is used in healthcare facilities or at home to provide a continuous flow of oxygen to the patient via a nasal cannula or mask. The product in the images is a medical main unit.

Quantity Information

The images show 1 unit of the Oxygen Concentrator main unit and 1 water bottle (humidifier) mounted on the device.

General Condition and Cosmetic State

The device is in a used condition. Color changes on the device’s outer casing, occurring over time and due to use, are noticeable. Particularly, the original beige/cream tone of the device’s upper plastic panel and lower cover is observed to have yellowed due to UV light or environmental factors.

Physical Deformation

• Front Lower Panel: Prominent black scuff marks and scratches are present on the beige plastic panel at the bottom of the device.
• Button Surroundings: Dirt accumulations and signs of use are visible around the control panel buttons (Timing+, Timing-).
• Body Joints: Dust and dirt residues are present at the joints of the plastic components.
• Break/Crack: No major break or crack affecting functionality has been detected on the device’s casing in the images.

Mechanical Components and Flow Meter

On the front face of the device, on the right side, there is a mechanical flow meter. This component is a ball-type (rotameter) that allows adjustment between 0 and 5 Liters/Minute. The scaling on the tube is graded up to a capacity of 5 L/min (5 liters per minute). The humidifier water bottle is in its slot and secured by a mechanical fastening (rubber/velcro).

Electronic Components and Screen Analysis

The images show that the device is operational (Power ON) and its electronic system is active. The blue LCD screen backlight is active, and the “P.O.” (Power On) LED indicator is illuminated in green.

LCD Screen Data:

• S. Times: 0001981 (This might be the number of times the device has been switched on and off in total).
• O.P. MPa: 0.164 / 0.109 (Operating Pressure. The observation of 0.164 in one image and 0.109 in another indicates that the device’s pressure cycle – PSA – is actively changing and the compressor is working).
• O. Time: 0000 02 (Operating time in the current session, in minutes).
• Acc. Time: 0004149 (Total accumulated operating hours. The device has been used for a total of 4149 hours).

LED Warning Lights:

The panel features LEDs for L.O2 (Low Oxygen), H.O2 (High Oxygen), H.T (High Temperature), L.P (Low Pressure), H.P (High Pressure), P.F (Power Failure), P.O (Power On). In the image, only the green light for P.O (Power On) is illuminated, indicating that the device is not currently showing any fault alarms.

Accessories

In the front-middle part of the device, there is a transparent humidifier water jar with a black lid. The lid’s connection part on the jar is red. The water jar currently appears empty. The power cable is attached to the device, but its end is not visible.

Label and Warning Information

In the upper right corner of the front panel, there are 6 points of usage warnings under the heading “CAUTION”:

1. Read the manual before use.
2. Non-professionals are prohibited from opening the device.
3. Clean the air inlet filter every 100 hours.
4. Clean the secondary filter every 300 hours.
5. Oxygen purity is 93%±3 at nominal flow.
6. SMOKING AND OPEN FLAMES ARE PROHIBITED (Emphasized in capital letters).

Additionally, the warning “USE NO OIL OR GREASE” is specifically mentioned due to the risk of combustion in contact with oxygen.

Usage Duration Assessment

The “Acc.Time: 0004149” displayed on the screen indicates that the device has operated for a total of 4149 hours. Oxygen concentrators generally have an expected lifespan of 10,000 to 30,000 hours (depending on brand quality standards). 4149 hours of use indicates that the device falls into the “second-hand” category but has not yet completed its economic life, suggesting a moderate level of operational life.

Current Fault and Potential Risk Analysis

In the images, the device’s “Power On” light is illuminated, and screen data (pressure values) are changing. No error code or red fault light is visible on the screen or LED panel. This indicates that the device is currently operating electronically and pneumatically.

As a potential risk; the yellowing and wear on the device’s exterior cosmetics suggest that the device might have been in an environment exposed to sunlight for a long time. This could lead to embrittlement of the plastic components. Furthermore, 4149 hours of use indicates that the device’s filter maintenance (inlet filter, HEPA filter) should be performed.

Conclusion

The examined oxygen concentrator, according to visual data, is an electrically operating device with a 5-liter capacity, cosmetically moderately worn (yellowing and scratches present) but with its mechanical integrity preserved. With a usage history of 4149 hours, it is in a condition to continue providing service if its maintenance is performed.
