Lifetime OX 5B Oxygen Concentrator Analysis Report

Device Identification

The device shown in the visuals is an electrically operated oxygen concentrator (oxygen generator) used for medical purposes. The device is medical equipment that takes ambient air, separates nitrogen, and provides high-concentration oxygen to the user. Its wheeled structure indicates it is portable (within a room).

Brand and Model

Upon examining the detailed label on the product’s rear panel and the identifiers on the device, the following definitive information has been obtained:

• Brand/Model: LIFETIME OX 5B
• Product Description: Oxygen Concentrator
• Manufacturer Technology Company: Oxytek Medical Technology
• Importer Company: Elmaslar Inc.
• Origin: Made in PRC (People’s Republic of China)

This information is clearly written on the metallized label on the rear of the device and has been 100% confirmed from the visuals.

Originality

The print quality, placement, and detailed technical information (importer company address, contact information, serial number format, CE mark, and warning texts) on the device’s label comply with industrial standards. It is understood that the product is a legal and registered medical device imported by Elmaslar Medikal. Visual details indicate that the product is original.

Areas of Use

This device is used to provide continuous or intermittent oxygen support to patients in conditions such as COPD (Chronic Obstructive Pulmonary Disease), asthma, lung infections, or respiratory failure. The device is designed for home use. The “Nebulization” button and its functions on the front panel indicate that the device can also be used for medication administration (nebulizer).

Quantity Information

The visuals show a total of 1 unit of the main oxygen concentrator unit and its associated components (water bottle, connecting hose).

General Condition

The device is in used condition. Its outer plastic casing predominantly exhibits a beige/yellowish color tone; this might be due to natural yellowing of the plastic over time due to sunlight or environmental factors, or it could be its original color. However, in terms of overall appearance, the device maintains its integrity and appears to be in clean condition.

Physical Deformations

No deep cracks, breaks, or dents have been detected on the device’s outer casing in the visuals.

• The front panel’s keypad and screen appear intact.
• There are no broken parts on the rear ventilation grilles (louver section).
• The wheels are in place.
• Slight superficial marks due to use are possible on the plastic surfaces, but no significant damage is visible in the photographs.

Mechanical Components

When mechanical parts are examined:

• Flow Meter: The transparent tube (flow meter) on the device’s front right side is intact. The adjustment ball inside is visible. The adjustment knob is in place.
• Wheels: The black wheels under the device are present and ensure the device stands stably.
• Humidifier Bottle Holder: The rubber/strap mechanism that holds the water bottle is present.

Electronic Components

The LCD screen on the front of the device is active, but the displayed “888888” usually indicates that the device is testing all segments upon initial power-on or is in standby mode. The symbols on the buttons (Time setting, Nebulization, Function) are legible. No broken cables or protruding circuit elements are visible.

Accessories

The following accessories have been identified on the device:

• Power Cable: A black, European-type (Schuko) grounded plug-ended electrical cable, integrated with or attached to the device, is present. No visible crushing or breakage is observed on the cable.
• Humidifier Water Bottle: A transparent reservoir, black-capped water bottle connected to the oxygen outlet is present. The connecting fittings on the cap appear intact.
• Intermediate Connection Hose: A short, transparent silicone hose, leading from the device’s main oxygen outlet to the humidifier bottle, is attached, and no bending/breaking is observed.

Label Information

Critical information on the label on the device’s rear side is as follows:

• Serial Number (SN): 5B201806010076
• Production Date: 06/2018
• Ref/Model: LIFETIME OX 5B
• Electrical Ratings: 230 VAC – 300 W ± 10% – 50 Hz
• Protection Class: IP X1 (Protected against vertically dripping water)
• Standards: CE 2460

Additionally, the label contains Turkish warnings such as “Should be used with doctor’s advice,” “Clean the filter at least every 30 days,” and “Keep away from fire.”

Dimensions and Compatibility

Referring to the visuals, the device appears to be close to standard nightstand dimensions and has a wheeled structure. It is a standard home-use device for adult use. No special pediatric (baby) equipment is present in the visual.

Year of Manufacture

According to the date information on the device’s label, the year and month of manufacture are June 2018 (06/2018).

Potential Malfunction Risk

Visual inspection does not reveal any critical damage (broken casing, severed cable, burn marks, etc.) that would prevent the device from operating. Although the product’s condition reflects its age (manufactured in 2018), it can be rated as “good.” However, the humidifier bottle and hoses are consumables; the user may need to replace these parts for hygiene purposes.
