5 Liter Oxygen Concentrator Detailed Analysis Report

Device Identification

The product in the image is an oxygen concentrator, a medical device that filters ambient air to produce high-purity oxygen for patients experiencing respiratory difficulties. It is an electrically powered, stationary type (home-use), and wheeled model.

Brand and Model

The device’s front panel, control buttons, and overall design have been thoroughly examined. In the lower right corner of the device, there is a logo consisting of a blue sphere and a green leaf figure, surrounded by the phrase “OXYGEN CONCENTRATOR”. However, the brand name in the logo is not clear and 100% readable. Therefore, to avoid misleading information, a specific brand name (e.g., Philips, Respirox, Yuwell, etc.) has not been stated. The design in the image generally exhibits the characteristics of Asian-origin devices that produce “generic” (OEM) products (cream-colored plastic casing, flowmeter on the left, humidifier slot in the middle). Since the scaling on the flow meter (debimetre) goes up to 5 liters, it has been definitively determined that the device is a 5 Liter capacity model.

Originality

The device features a typical Far Eastern medical device design. The warning labels and screen prints on it appear to comply with standards. The casing structure and the assembly of parts indicate that it is an industrially mass-produced device. Rather than being a replica of a specific brand, it is believed to be a standard contract manufactured model.

Areas of Use

This device is designed for patients with COPD, lung diseases, or respiratory failure to receive long-term oxygen therapy (LTOT) in a home environment. It takes in ambient air, separates nitrogen, and delivers oxygen with over 90% purity to the patient. The product is not an accessory but the main device for treatment.

Quantity Information

The focal point of the image is 1 unit of oxygen concentrator. (Although similar devices are visible in the background, the analysis focuses only on the device in the foreground).

General Condition

It is observed that the device is second-hand and has been used extensively. Its external condition is “moderate”. The aesthetic appearance of the product has deteriorated due to storage conditions or usage duration.

Physical Deformation

• Color Change (Yellowing): The plastic outer casing of the device has yellowed significantly compared to its original color. This is the most prominent sign that the device has been exposed to sunlight (UV) for a long time or that the plastic has aged.
• Stains and Scratches: Numerous black scuff marks, stains, and dirt are present on the front panel, especially towards the lower parts.
• Surface Cleanliness: Dusting and usage dirt are present on the general surface of the device.

Mechanical Components

Although the integrity of the casing appears to be preserved, the on-off switch (rocker switch) on the upper right control panel is intact. The rubber tension strap that should hold the humidifier bottle is present but appears loose. The wheels at the bottom are in place, and the front wheels show wear due to use.

Electronic Components

The device’s upper panel features an LCD information display and status LEDs (pressure and power status indicators such as PO, PF, LP, HP). Since the device is off in the image, it could not be determined whether the screen is working or if there are any pixel errors.

Accessories and Missing Parts

• Missing Part (Water Container): The humidifier bottle, which should be placed in the recessed area to the immediate right of the flowmeter on the front of the device, is missing. Without this part, dry air comes from the device, which can dry out the patient’s mucous membranes.
• Socket Inputs: A metal oxygen outlet nipple is present on the upper part.
• Cable: The power cable is not clearly visible from the visual angle (likely at the back).

Battery Status

This type of stationary oxygen concentrator typically does not have an internal battery; they operate directly with mains electricity (220V). There is no evidence in the image that it is a portable/battery-powered unit.

Label Information and Warnings

On the front right side of the device, there is a label titled “CAUTION”. The readable items are as follows:

• Read the user manual before operation.
• Non-professionals are prohibited from opening the machine’s casing.
• Clean the air inlet filter every 100 hours of use.
• Clean the secondary filter every 300 hours of use.
• Oxygen purity: 93% ± 3% (At nominal flow rate).
• No smoking and keep away from open flames.
• Do not use oil or grease.

Size and Compatibility

The device is a standard home-use concentrator size suitable for adult patients (approximately knee-height). It has a flow meter adjustable from 0-5 Liters/minute, indicating its suitability for most standard oxygen therapy prescriptions.

Potential Malfunction Risk and Recommendations

The yellowing and heavy dirt in the image suggest that the device might be an old production or a product that has been stored in a warehouse environment for a long time. In such devices, if the specified 100 and 300-hour filter maintenances are not performed, the efficiency of the internal compressor and zeolite tanks may decrease. Although the device appears mechanically sound, before being put back into use, replacing its filters, measuring the oxygen purity level, and performing internal cleaning are critically important for performance and hygiene.
