Plusmed Oxygen Concentrator Analysis Report

Device Identification and Applications

The device shown in the images is an oxygen concentrator that produces oxygen from ambient air for patients requiring respiratory support. It is suitable for use in pulmonary diseases, home care processes after intensive care, and general respiratory therapies. The brand of the device has been identified as Plusmed from the logo located in its lower right corner. There is no label or writing indicating the device’s model in the images. According to the flow meter (rotameter) on the device, the product has a capacity of 5 liters/minute.

General Condition and Physical Deformations

The device is in used condition. No structural integrity issues, breaks, or deep cracks have been observed on the white and light blue plastic body. However, on the front surface of the device, especially in the cavity where the humidifier bottle is placed and at the edge joints, there are superficial dirt, stains, and dust accumulation due to use. Normal dirt accumulation due to ground contact is observed on the wheels located at the bottom of the device.

Mechanical and Electronic Components

• Control Panel: The black on/off (I/O) switch and the black plastic cover next to it are physically intact. There is no tearing or fading on the four yellow membrane buttons (for timer, mute, etc. functions) located at the bottom.
• Flow Meter (Rotameter): The transparent tube scaled between 0 and 5 L/min is intact. The black indicator ball inside is at the lowest level (0 position).
• Oxygen Outlet Nozzle: The metal oxygen outlet fitting located at the top of the slot where the humidifier bottle is attached is intact, with slight discoloration/oxidation marks present on it.
• Wheels: The black swivel wheel visible in the image is physically intact and shows no breaks.

Screen Analysis and Usage Time

The colored digital screen on the front panel of the device is active, and the data on it is clearly readable. The data displayed on the screen are as follows:

• 95%: Indicates the instantaneous oxygen purity produced by the device.
• Running time 0006: Refers to the current session duration (on-time) of the device.
• Elapsed time 06493: States that the total usage time of the device since it left the factory is 6493 hours.

Accessories and Missing Parts

Only the main unit of the device is present in the images. The humidifier water bottle, which needs to be integrated into the system for oxygen therapy, is not present on the device. Furthermore, consumables such as nasal cannulas or oxygen masks, which provide oxygen delivery to the patient, are not found in the images.

Potential Malfunction Risk

In the images, there is no physical damage, broken part, or error code displayed on the screen that would prevent the device from operating. The external condition of the device is generally good. The total usage time of 6493 hours read on the screen indicates that the device has been in service for a long time. Although a visual malfunction cannot be detected, for devices with such high operating hours, routine maintenance of internal filters and the compressor system is important for the device’s efficiency. The dirt on the outer casing is merely cosmetic and does not pose a functional risk.
