Lifetime OX 5B Oxygen Concentrator Analysis Report

Device Identification, Brand and Model Information

As a result of detailed visual analysis, the examined device has been identified as an Oxygen Concentrator used for medical purposes. Based on the original manufacturer label on the rear surface of the product and the front panel design, the brand and model information has been determined with 100% certainty as follows:

• Brand: Lifetime (Manufacturer: Oxytek Medical Technology)
• Model: OX 5B
• Product Type: Oxygen Concentrator
• Origin: MADE IN PRC (People’s Republic of China)
• Importer Company: ELMASLAR A.Ş.

Areas of Use

This device is used to provide high-concentration oxygen support to patients by separating air from the atmosphere. It is designed for patients suffering from respiratory failure such as COPD, asthma, and pulmonary fibrosis, enabling them to receive long-term oxygen therapy at home or in a clinical setting. Furthermore, the “Nebulization” button and outlet port on the device’s control panel indicate that the device can not only deliver oxygen but also be used for medicated vapor therapy (nebulizer function).

General Condition and Status Assessment

The device generally has a used appearance. Typical color changes (shifting to beige/yellowish tones) that can occur over time and due to light exposure are observed on the plastic outer casing. The overall integrity of the device is maintained, and no major damage such as disintegration or fragmentation is visible on its body from the outside.

Physical Deformations and Cosmetic Examination

• Casing: The device’s outer plastic casing may have superficial wear due to use, but no deep cracks or fractures have been detected.
• Labels: The technical information label on the rear panel is in place, although there are slight lifts at its edges and wear on its surface; despite this, the text is legible.
• Dirtiness: There is a high probability of dust accumulation in the device’s rear ventilation grilles and recessed areas due to use. No water residue is observed in the humidifier bottle reservoir; the bottle is empty.

Mechanical and Electronic Component Analysis

• Wheels: Wheels facilitating easy transport are observed at the bottom of the device.
• Buttons and Switches: The “ON/OFF” power switch, “4 AMP” fuse button, and touch membrane keypad on the front panel are physically in place. The power switch is in the “OFF” position in the image.
• Flowmeter: The tube-shaped flow indicator located on the front right side is intact. The ball level inside is at “0”, confirming that the device is not operating. The scaling, as far as can be understood from the image, is in the 0-5 LPM (Liters/Minute) range.
• Input/Output Ports: A metal or hard plastic connector is visible at the oxygen output end, and the hose leading to the humidifier is connected here.

Accessories and Connecting Parts

The total number of parts and accessories identified as a result of the analysis in the images is as follows:

• 1 Unit Oxygen Concentrator Main Unit.
• 1 Unit Humidifier Bottle – Secured to the front surface of the device with a black rubber/cord.
• 1 Unit Interconnecting Hose (between the humidifier and the device outlet).
• 1 Unit Integrated Power Cable (European standard plug type).

Note: The nasal cannula (nosepiece) or mask extending to the patient is not present in the images. These parts are missing and must be acquired separately for use.

Label Information and Technical Data

The precise technical data obtained from the silver-colored label on the back of the device is as follows:

• Serial Number (SN): 5B201806010076
• Manufacturing Date: 06/2018
• Voltage/Power: 230 VAC – 50 Hz, Power consumption 300 W (± 10%)
• CE Certificate: CE 2460 approval code is present.
• Warnings: The phrases “The device should be used under the advice of a specialist doctor.”, “Do not smoke”, “Replace the filter with a new one at least once every 30 days” are in Turkish.

Screen Analysis

The device’s front panel features a digital LED/LCD screen. In the image, traces of segments in the “888888” format are visible on the screen. Since the device is in the OFF position (Power button at 0), this image reflects the screen’s structure, not its active operation. Around the screen, there are indicator areas for status such as “Nebulization”, “Timing”, “Normal”, “Low”, “Alarm”.

Manufacturing Year and Estimated Usage Period

The 06/2018 notation on the device label indicates that the product was manufactured in June 2018. This date reveals that the device has an approximate history of 7-8 years. The operating hours (Total Hours) is data that can be seen on the device’s digital screen, but since the device is turned off, clear hour information (run time) cannot be read from the image.

Potential Failure Risk and Warnings

No cracks, burn marks, or severe impacts were observed on the device during the visual inspection, indicating that the physical condition of the device is at an acceptable level. However:

• Due to the manufacturing year being 2018, the possibility that the internal molecular sieves (sieve bed) may have reached the end of their lifespan or caused performance loss should be considered.
• Considering the warning “Replace the filter at least once every 30 days” stated on the rear label, the inlet filters (behind the grille in Image 3) should be checked. Clogging can lead to performance degradation.
• Before operating the device, screen functions and oxygen purity should be tested. Visually, there are no external indications suggesting “It is faulty”.

Quantity Information

In the images, 1 (one) unit of the device and its integrated accessories (water container, cable) are displayed.
