Plusmed Brand Portable Oxygen Concentrator Analysis Report

Device Identification

The product shown in the visuals is a medical device used to provide respiratory support. Upon examination of its structure, dimensions, and accompanying accessories (car charger, carrying bag, battery), it has been determined that this device is a Portable Oxygen Concentrator capable of operating independently from mains electricity.

Brand and Model Information

Detailed examination of the device’s front panel and top section revealed the following findings:

• Brand: The Plusmed logo is clearly and legibly displayed in orange font on the top surface of the product.
• Model: A faint model code/text is located on the device’s control panel, directly below the screen. However, due to the resolution of the visuals, this code could not be read with 100% clarity, so an estimated model number has not been provided to avoid misinformation. The device’s form factor is consistent with the brand’s portable oxygen concentrator series.

General Condition and Originality

Visually, the product exhibits original Plusmed design and craftsmanship. The case structure, color tone, and accessory compatibility indicate that the product is an original medical device. The overall condition of the device is very high, and it can be described as “minimally used” or “like new”.

Cosmetic Inspection and Physical Condition

Detailed observations regarding the physical condition of the device are as follows:

• Screen and Panel: It is clearly visible that the factory-issued transparent protective film (label) is still present on the control panel, screen, and keypad area. Air bubbles and wrinkles on the film are not signs of use; rather, they indicate that the underlying panel is protected from scratches and remains clean.
• Casing: No visible yellowing, cracks, breakages, or deep scratches have been detected on the device’s white plastic casing. The case seams are in proper condition.
• Deformation: No visible deformation or physical damage is present on the device’s body.

Accessories and Package Contents

When the product and accessories in the visuals are itemized, the set is observed to consist of the following parts (5 main parts in total):

• 1 Main Unit: Plusmed brand oxygen concentrator.
• 1 Carrying Bag: A black-colored special carrying bag, suitable for the device’s dimensions, featuring ventilation holes and a transparent window.
• 1 Car Charger Adapter: A black-colored power cable with a car cigarette lighter input. This accessory proves the device’s suitability for use during travel.
• 1 Battery: A white-colored external battery module, presumed to attach to the bottom of the main device (visible openly on the ground in the 2nd visual).
• 1 AC Adapter (Estimated): The box-like part wrapped in white foam/protective packaging is assessed to be the device’s mains power adapter.

Technical Details and Component Inspection

Technical inspection notes based on the visuals are as follows:

• Battery Condition: The device’s battery is externally present in the visual. No swelling, casing gaps, or physical damage has been observed on the battery.
• Mechanical Components: The oxygen output port (cannula input) appears robust on the top part of the device. No missing components such as the carrying handle or filter covers are noticeable among the movable parts.
• Screen: As the device is in the off position, no comment can be made regarding the screen’s operational status, but its physical integrity is complete.

Areas of Use

This device is designed to meet the oxygen needs of patients with chronic conditions such as COPD and respiratory failure. Particularly due to its battery-powered nature and car kit, it is suitable for:

• Daily home use,
• Use during travel (car, airplane, etc.),
• Use as a backup device to prevent patients from lacking oxygen during power outages.

Evaluation Result

The examined Plusmed brand device is visually in an extremely clean and well-maintained condition. The fact that even the protective film on the keypad has not been removed indicates that the device has either been used very little or meticulously preserved throughout its lifespan. No mechanical breaks or missing parts (the complete accessory set is an advantage) have been observed. While the operational status of the product could not be tested, its physical appearance is reassuring.
