Oxygen Concentrator Analysis Report

Overview and Device Identification

The product shown in the images is an oxygen concentrator device that separates gases from ambient air to produce pure oxygen, which it then delivers to patients in need of respiratory support. The device has a compact design suitable for home use. It is understood to operate on electricity and generate oxygen by processing air.

Usage Areas and Quantity Information

This device is used to provide continuous and reliable oxygen to patients in conditions such as respiratory failure. The images show 1 unit of oxygen concentrator. No additional accessories (such as an oxygen mask, nasal cannula, extension tube, etc.) are visible on the device, other than the integrated humidifier reservoir.

General Condition and Assessment

The device generally has a clean and well-maintained appearance and has been assessed as “lightly used”. The most important evidence for this assessment is the usage information of 0139 hours, visible on the device’s digital display in the “TOTAL TIME” section, which indicates the total operating time. This low operating time suggests that the device has been used very little.

Physical and Mechanical Condition

No significant deformation such as serious impact, crack, dent, or discoloration has been detected on the device’s white and black casing. However, there is a fine scratch or a superficial crack on the protective film over the digital display. This condition does not appear to affect the readability or functionality of the screen.

• Casing: Generally clean and undamaged.
• Mechanical Parts: The flow meter and adjustment knob, used for setting the oxygen flow rate and bearing the inscription “LPM” (Litre Per Minute), are physically in sound condition.
• Humidifier Reservoir: The water reservoir located at the front of the device, illuminated by a blue LED light inside, is intact. The reservoir has a “Highest Water Level” mark indicating the maximum level for water filling.

Electronic Components and Display Analysis

It is understood that the device is plugged in and operational, indicated by its illuminated digital display and the light in the humidifier reservoir. No visible malfunctions are present in the device’s electronic components.

• Digital Display: The LED display provides clear information about the device’s current status. The “FAN” indicator denotes that the internal cooling fan is active. The screen is also designed to show settings such as oxygen level and timer.
• Usage Duration: The most critical data on the screen is the phrase “TOTAL TIME 0139 hrs”, indicating the device’s total operating life. This confirms that the device has only operated for 139 hours since leaving the factory.
• Ports and Connections: A single metal oxygen outlet, labeled “Oxygen Outlet”, is present on the device’s front panel. No other connection ports are visible.

Label Information and Accessories

During the inspection of the device, no label containing technical information such as serial number, lot number, reference code, or year of manufacture was detected. A yellow warning label (“Tips”) containing usage recommendations in English is located on the device’s bottom right corner. No documents or additional accessories belonging to the device, such as a power cable, user manual, or invoice, are present in the images.

Potential Risk Assessment

During the examination of the device in the images, no negative conditions such as rust, cable damage, excessive wear on the casing, or burn marks that could indicate a serious malfunction risk were encountered. The device having a very low usage time of 139 hours indicates its high condition and that its mechanical components are practically new. The scratch on the screen protector is merely a cosmetic flaw and does not impede the device’s operation.
