GALENA CTB01-A00E Oxygen Concentrator Analysis Report

Device Identification

The examined images belong to an oxygen concentrator, which is a medical respiratory support device. The device is designed to take ambient air, separate nitrogen, and deliver high-concentration oxygen to the patient. The device has a vertical, wheeled, fixed structure suitable for home use.

Brand and Model Information

Based on the information on the device’s front panel and technical label in the images, the brand and model identification is as follows:

• Brand: GALENA
• Model: CTB01-A00E (The marked model box on the label is next to this model)
• Product Type: 5 LPM Oxygen Concentrator
• Manufacturer: EMG TECHNOLOGY CO., LTD. (Taiwanese origin)
• Importer: Galena Sağlık ve Gıda Ürünleri Tic. Ltd. Şti.

Originality and Place of Manufacture

The detailed company information on the technical labels on the back of the product, the CE (0434) certification logo, the barcode structure (starting with 8698726, a company code of Turkish origin – referring to the importer), and the serial number format indicate that the device is an original GALENA product (manufactured by EMG Technology). The manufacturer’s address is stated as “Taiwan, R.O.C.”, which indicates that the product is manufactured in Taiwan.

Areas of Use

This device is designed for patients who require supplemental oxygen support due to COPD, asthma, lung failure, or other respiratory conditions. It is suitable for use in home environments, nursing homes, and clinical services in hospitals. The humidifier bottle in the image ensures that the dry oxygen coming from the device is humidified to prevent it from drying out the patient’s airways.

Quantity Information

The images show a total of 1 unit of the oxygen concentrator main unit and 1 unit of the humidifier water bottle attached to the device.

General Condition and Cosmetic Examination

The device appears to be in a used condition overall. The following details have been observed on its casing and exterior surface:

• Casing Condition: No significant cracks or major fractures are visible on the plastic outer casing. The blue and gray colored body maintains its integrity. However, superficial dirt resulting from use is present.
• Physical Deformations: Slight openings or alignment defects may be visible at the joints of the left side panel (around the mold lines), but this is generally common in such plastic molded products and is not a major damage. Wear marks are present on the wheels and lower parts of the device.
• Mechanical Components: The oxygen flow adjustment knob (flowmeter knob) and the on/off (I/0) switch on the front panel appear to be intact. The wheels are in place. The device’s carrying handle (on the top) appears sturdy.

Technical Data and Label Analysis

The technical data and device identification information read from the label (REF 5) on the back of the device are as follows:

• Serial Number (SN): CT11D00998
• Date Code / Production: While no clear date is printed on the label, the “11” indication in the serial number and the general structure of the model might suggest a 2011 production year, but this is not conclusive data.
• Power Specifications: 230 VAC, 50 Hz, 1.9 Amp.
• Maximum Power Consumption: 420 Watt
• Operating Principle: Single Phase
• Maximum Flow Rate: 5 LPM (5 Liters Per Minute)
• Oxygen Purity: According to the label, it provides purity in the range of %93 ± %3. It is stated that purity can reach %95.5 at low flows and drop to %87 at maximum 5LPM flow.
• Noise Level: Not specified in the visual.
• Warnings: Under the heading “IMPORTANT NOTE” on the device, it is clearly stated that a regulator (voltage stabilizer) should be used against voltage irregularities and that a spare oxygen cylinder should be kept for power outages.

Front Panel and Screen Analysis

The control panel (Interface) on the front of the device includes the following features:

• Warning Lights (LED Indicators): From left to right, there are “Service Required” (likely Red), “Low O2” (likely Yellow), “Normal O2” (likely Green), and “Power” lights. The status of the lights could not be analyzed as the device was off in the image.
• Flow Indicator (Flowmeter): A black ball is present inside a transparent tube. It has a scale from 1 to 5, which confirms that the device provides a maximum of 5 liters of oxygen per minute.
• LCD Screen: A small digital clock/counter screen (likely an hour meter) is present at the very top, but the value on it cannot be read as it is off.

Accessories and Battery Status

• Humidifier Bottle: A water container is attached to the front compartment of the device. The condition of the container appears slightly cloudy/limescale-laden in the image; it may need to be replaced or thoroughly cleaned for hygiene reasons. A hose connection fitting is visible inside.
• Power Cable: A black power cable with an European-type grounded plug is present at the back of the device. No visual crushing or breakage was detected on the cable; it is gathered with a hook-and-loop strap.
• Filter: A black, spongy cabin air inlet filter is visible on the rear panel. Its black color could be due to the filter material itself or from dust accumulation. Its cleanliness needs to be checked.
• Battery: This type of home-use stationary device typically does not have an internal battery and operates solely on mains electricity. There is no indication on the device that it operates with a battery.

Potential Malfunction Risk and Evaluation

The outer casing of the device is robust and integrated; in this respect, its condition is good. However:

• Hygiene Risk: The humidifier water bottle is a personal and replaceable part; it is highly recommended to replace it for second-hand use.
• Filter Condition: The black filter at the back is critical for the motor’s air intake. If it is dusty, it could cause the motor to overheat.
• Service Life: If the serial number indicates 2011 (SN: CT11…), the lifespan of the “zeolite” tanks (the substance that separates oxygen) inside the device may have decreased. Measuring oxygen purity with an analyzer device is important to confirm the device’s performance.
• Electrical Warning: The “Use with a regulator” warning on the label indicates that the device is sensitive to voltage fluctuations. Adhering to this warning will prevent potential circuit board failures.
