Galena Oxygen Concentrator Analysis Report

Device Identification

The product examined in the visuals is an oxygen concentrator, a medical device that filters ambient air to produce high-purity oxygen for patients requiring respiratory support. The device is a wheeled, vertical model suitable for home use.

Brand and Model

As a result of detailed visual analysis, the GALENA logo, clearly legible in red, was identified on the front lower panel of the device. The general design features of the device (casing structure, control panel layout) are consistent with standard 5-liter capacity oxygen concentrators; however, there is no specific model number (e.g., SY-10 or OC-5) on the front face that complements the brand. Therefore, the product has been identified by the brand GALENA.

General Condition and Physical State

The device is in “used” condition. Noticeable dirt, yellowing, and ingrained stains are observed on the white upper casing and around the control panel of the product. Specifically, there are blackish friction marks and layers of dirt around the power on-off button on the right side of the screen and on the upper plastic surfaces. The grey middle body section shows friction-related marks and cosmetic wear. The overall impression is that the device’s exterior has not been cleaned and it has been neglected for some time.

Originality

The Galena logo on the product, the device’s general casing structure, warning labels, and screen fonts indicate that this product is an original Galena brand oxygen concentrator (or a standard medical product imported by the Galena brand). There is no visual evidence to suggest it is an aftermarket or copy product.

Technical Analysis and Screen Data

The device was observed in operational status. The data on the LCD screen shows the current operating status:

• O.P. MPa (Operating Pressure): Operating pressure values of 0.098 MPa and 0.113 MPa (varying between visuals) are readable on the screen.
• O.C. V/V (Oxygen Concentration): The value %00.0 is displayed on the screen. It can be assumed that the device is still in the warming-up phase or not taking a measurement at that moment.
• O.Time (Instantaneous Operating Time): The device has been operating for 9 seconds (0000:09) since its last power-on.
• Acc.Time (Total Accumulated Operating Hours): It is clearly understood from the “0001005” display on the screen that the device has been used for a total of 1005 hours throughout its lifespan.

Control Panel and Warning Lights

There are 6 LED indicators and their explanations on the panel:

• L.O2 / H.O2: Low and High Oxygen warning.
• H.T.: High Temperature.
• L.P. / H.P.: Low and High Pressure.
• P.F.: Power Failure.
• P.O.: Power On – In the visual, the green light is actively illuminated under this indicator.

Mechanical Components and Accessories

The following components were identified during the visual inspection:

• Water Reservoir (Humidifier): A transparent humidifier bottle with a blue cap is present, placed in the slot in the middle section of the device. The bottle appears empty.
• Flow Meter (Flowmeter): On the right side, there is a manually adjustable, ball-type flow meter. From the scale on it, it is understood that the device likely has a capacity of 0-5 Liters/Minute.
• Control Buttons: Below the screen, “Timing +” and “Timing -” buttons are present for timer adjustment.
• Power Switch: A black mechanical “POWER” switch (I/O) is located at the top right.

Label and Warning Information

The English warning text (Caution) on the front panel specifies the following important technical details:

• The user manual must be read before use.
• The air inlet filter must be cleaned every 100 hours of operation.
• The secondary filter must be cleaned every 300 hours of operation.
• Oxygen purity is %93 ± %3 at the nominal flow rate.
• Smoking is prohibited, and do not approach with fire.
• Do not use oil or grease.

Potential Fault Risk

There is no definitive evidence of a fault preventing operation, such as “broken” or “error message,” in the visuals. However, the heavy soiling on the device’s casing suggests the possibility that its maintenance (filter cleaning, etc.) might have been neglected. The total operating hours are 1005 hours; this duration indicates that the device’s periodic maintenance (filter replacement) time may have arrived or passed. Clogged filters can affect oxygen quality and the device’s motor performance. Since the device’s oxygen concentration (O.C.) appears as %00.0 on the screen, sensor calibration or warm-up time should be checked.

Areas of Use

This product is used to provide long-term oxygen therapy (LTOT) at home for chronic lung diseases such as COPD, asthma, pulmonary fibrosis, or in cases where blood oxygen saturation drops. It is suitable for use only with medical necessity and doctor’s recommendation.

Quantity Information

The visuals show a single set, consisting of 1 main device and 1 humidifier water container attached to it.
