FORAS Oxygen Concentrator Visual Analysis Report

Device Identification and Product Description

The product in the visual is an electrical device designed to provide medical respiratory support. Upon examining the device’s general form factor, its front-panel digital display, adjustment knob, flow indicators, and output nozzle, it has been determined that this device is an Oxygen Concentrator, which takes ambient air, separates nitrogen through molecular sieves within, and provides high-concentration oxygen to the patient. The indications “OXY”, “5 L” (capacity), and “L” (Liters/minute flow unit) on the panel confirm this identification.

Brand and Model Information

The lettering within an oval logo on the front surface of the product, on the left side, has been examined in detail. The inscription “For AS”, written in a serif font, is clearly legible in the logo. This logo and the device’s design language point to the well-known medical device manufacturer brand FORAS. Although a distinct alphanumeric code (e.g., OXY-500) for the model name is not visible in the image, it is definitively seen from the markings on the front panel that the device is a 5 Liter capacity model.

Screen and Indicator Analysis

The device’s LCD screen is active and illuminated with a blue backlight. A detailed analysis of the data displayed on the screen is as follows:

• Time Counter (00000 min): On the left side of the screen, a 5-digit value “00000” is visible along with the “min” (minutes) indicator. This indicates that the device’s operating hour counter has either been reset or that the current session duration is still at its beginning.
• Oxygen Status Indicator (O2 Normal): The “O2 Normal” indicator, illuminated in green, is active in the bottom left corner of the screen. This suggests that the device’s oxygen sensors are detecting production values (theoretically) within the normal range.
• Percentage Value (28 %): In the center of the screen, the number “28” is displayed in large font, accompanied by a small “%” symbol. This value typically represents the oxygen purity level. Note: If the device has just started operating (time counter 0), the purity might still be climbing from ambient levels (approximately 21%). However, the appearance of a low value like 28% despite the green “Normal” light being on is a notable data inconsistency.
• Flow Rate (4.8 L): On the right side of the screen, the number “4.8” is visible, accompanied by the letter “L”. This indicates that the device’s current flow output is set to 4.8 liters per minute.
• Power Icon: An lightbulb-like icon is lit in the top right, indicating that the screen and the device are on.

Physical Condition and Mechanical Components

Based on the examination of the visual, the physical and mechanical condition of the device is as follows:

• Casing: The device has a white hard plastic body. Within the lighting conditions and angle of the visual, no significant cracks, breaks, or dents have been detected on the outer casing.
• Control Knob: The circular manual flow adjustment knob (flowmeter knob) located on the right side of the panel is present and in place.
• Output Nozzle: A metallic-looking oxygen output tip (cannula connection point) is visible on the upper left side of the device and appears to be intact.
• Carrying Handle: An integrated carrying handle is located on the top part of the device.

Areas of Use

This device is used for patients suffering from respiratory insufficiency, such as COPD, asthma, or lung infections, to receive long-term oxygen therapy (LTOT) in home or clinical settings. It enriches ambient air and delivers high-concentration oxygen to the patient via a nasal cannula or mask.

General Condition and Originality

The lettering, logos, and screen quality on the device are in line with industrial standards, strengthening the belief that the product is an original FORAS production. The device is operational (screen active), but its general cleanliness could be assessed as “used product” condition due to the dimness of the visual.

Quantity Information

Only 1 unit of oxygen concentrator device is visible in the image.

Accessories and Connections

Apart from the main body of the device, external accessories such as a nasal cannula, humidifier water bottle, or spare filters are not visible in the image. Although it is understood that the power cable is connected to the device due to the screen being operational, the physical condition of the cable cannot be clearly discerned in the visual.

Potential Status Note

Despite the device’s “O2 Normal” green light being on, the “% 28” value on the screen (if it represents oxygen purity) is technically well below medical standards (generally 90% and above). Although the “00000 min” duration indicates that the device has just been turned on, it would be beneficial for the buyer to check the device’s sensor calibration and oxygen production performance. The device is operational, but this data inconsistency may require a technical inspection.
