Detailed Analysis Report of Portable Oxygen Concentrator and Accessories

Device Identification and Intended Use

The main product in the visuals is a portable oxygen concentrator designed for patients requiring respiratory support. The device is used to take ambient air, separate nitrogen, and provide high-concentration oxygen to the user. The set also includes a wheeled transport stand (trolley) to facilitate device portability, a protective carrying bag, and various power adapters. The product has a compact structure suitable for both home use and travel.

Brand and Model Information

A detailed examination of the visuals revealed no manufacturer brand (Logo, name, etc.) or distinct model code on the device’s casing or screen. The device’s design (gold-colored front panel, white side covers, top carrying handle) resembles that of imported portable oxygen devices typically sold under various OEM brands. However, since no brand name or label could be 100% confirmed in the visuals, no assumptions were made, and the device’s brand and model are not specified.

Components and Quantity Information in the Visuals

A total of 8 main components and accessories have been identified in the visuals:

• 1 Unit Portable Oxygen Concentrator (Main unit).
• 1 Unit Black, specially designed carrying bag/backpack with a transparent window for the device.
• 1 Unit Foldable, telescopic-handle transport trolley.
• 1 Unit AC/DC Power Adapter (In the form of a black box).
• 1 Unit Mains power cable (for the adapter).
• 1 Unit Car cigarette lighter power cable.
• 1 Unit Pink external power converter/inverter (with a universal power outlet).
• 1 Unit Packaged nasal oxygen cannula.

Condition and Status Assessment

The overall appearance of the product indicates it is second-hand, in a clean and well-maintained condition. Upon close inspection, slight superficial hairline scratches and loss of shine due to light use are visible on the “Gold” (golden yellow) front panel of the main unit, especially on the carrying handle (Visual 3). However, no cracks, fissures, or deep impact marks were found on the device casing or the white plastic side covers. The screen surface is clean. The transport trolley and bag appear sturdy, with the bag’s zippers and stitching intact.

Technical Specifications and Component Examination

The controls and indicators on the device’s front panel are as follows:

• Digital Display: An LCD information display is located on the upper part of the device. The screen has areas for a timer, total operating hours, and active function symbols. Since the screen is off in the visual, instantaneous values cannot be read.
• Control Panel: Immediately below the screen, there are physical buttons controlling “O2 on/off,” “Time set -,” “Time set +,” and “Anion” (Negative ion) functions.
• Flowmeter: A manually adjustable ball-type flowmeter is located on the lower right side of the device. Although the scale on it cannot be clearly read from the visual, it has the stepped adjustment structure typically seen in portable devices.
• Output Port: The oxygen outlet tip is metal and located on the front face of the device. Additionally, the slot where a humidification unit can be attached appears empty (An external humidification bottle is not attached to the device in the visual, but a blue-capped bottle-like part is visible in the bag’s pocket in visual 1).

Electronic Components and Battery Status

While it is not definitively clear from the visual whether the device has an internal battery, the accompanying pink box (an inverter-like unit) and car charging cable indicate that the product can operate with mobile power sources. No cable crimping or stripping is observed on the black adapter unit. The pink power unit has a universal power outlet, ventilation holes, and an on/off switch; this component might be used to make the device compatible with car electricity or different power sources.

Compatibility and Usage Areas

Due to its compact dimensions, the device is more suitable for traveling patients or individuals who require oxygen support outdoors, rather than solely for in-home use. The transparent front of the black carrying bag allows the screen to be seen and buttons to be accessed without removing the device from the bag. The telescopic transport trolley at the back enables the device to be pulled like a wheeled suitcase instead of being carried on the back.

Potential Malfunction Risk

During the physical examination of the visuals, no concrete signs of malfunction (broken parts, severed cables, burn marks, etc.) that would prevent the device from operating were identified. The product is in “good” cosmetic condition. The oxygen cannula is in its sterile packaging and appears unused. There might only be standard signs of use on mechanical components (wheels, zippers), but no significant risk is observed.
