Yuwell Spirit-3 Portable Oxygen Concentrator Analysis Report

Device Identification

The product examined in the visuals is a medical device designed for patients requiring respiratory support. As a result of the visual analysis, it has been determined that the device is a “Portable Oxygen Concentrator” which filters ambient air and provides concentrated oxygen to the patient, powered by mains electricity or a battery. The compact structure of the device and its carrying bag indicate its suitability for mobile use.

Brand and Model

Following detailed examinations of the product, its carrying bag, and original box, the brand and model information has been definitively determined:

• Brand: Yuwell
• Model: Spirit-3

This information has been verified by the print on the carrying bag on the front of the device, as well as the “Spirit-3 PORTABLE OXYGEN CONCENTRATOR” inscription on the product box shown in the third visual. There is no speculative identification.

Areas of Use

The Yuwell Spirit-3 is used to provide supplemental oxygen support to patients with COPD (Chronic Obstructive Pulmonary Disease), pulmonary fibrosis, or other respiratory insufficiency conditions. Due to its portability, it is designed to meet patients’ oxygen needs while traveling, in a vehicle, or during daily activities outside the home. It is suitable for use on planes, in cars, and outdoors.

General Condition and Usage Time

Upon examining the data on the device’s LCD screen, the phrase “COUNT 00126 h” is visible. This indicates that the device has been used for a total of 126 hours. Considering that oxygen concentrators typically have a lifespan of thousands of hours, 126 hours of use suggests the device is in a “near-new” or “very lightly used” condition.

Physical Deformation and Cosmetic Condition

No significant physical deformation such as deep scratches, breaks, cracks, or discoloration has been detected on the device’s white plastic casing and control panel. Only very slight superficial marks, due to use or ambient dust, may be visible on the top control panel, but these are wipeable. No tears or unraveling are visible in the fabric of the carrying bag; it is in a clean condition.

Mechanical and Electronic Components

According to the examination of the visuals:

• Screen: The LCD screen is bright, with vibrant and colorful pixels. No dead pixels or cracks are visible.
• Buttons: The On/Off, Alarm Mute, and (+ / -) adjustment buttons on the device’s top panel appear solid and in place.
• Body: The ventilation grilles on the sides of the device are open and clean; no blockages are visible.

Screen Analysis and Operating Status

The device is displayed in operating condition. The warnings and icons on the screen are as follows:

• Warning Message: The screen displays the warning “No Breath Detected”. Below it, the instruction “Check cannula” is present. This situation does not indicate that the device is faulty; rather, it shows that its sensors are working correctly and that this warning is normal when the cannula is not attached to a patient or when the device is operating idly.
• Setting Level: The number “3” is visible in large font on the screen. This indicates that the device’s oxygen flow setting is at level 3 (Pulse mode).
• Language: The device interface has been determined to be English.

Battery Status

In the lower-left corner of the screen, a green battery charge icon and the “87%” indication are clearly visible. This proves that the battery holds a charge and actively powers the device. The visuals also show an external white ‘Li-ion’ labeled battery pack in its plastic packaging. Although it cannot be definitively determined from the visual whether the device was operating with a battery installed on it at that moment or by using the battery resting on the ground in the photo, active power is observed in the system.

Accessories and Quantity Information

The list of total parts and accessories present in the visuals is as follows:

• 1 Unit Yuwell Spirit-3 Main Unit
• 1 Unit Grey Original Carrying Bag (with strap)
• 1 Unit Standard AC Adapter (for mains power, brick-type)
• 1 Unit DC Car Charging Adapter (cigarette lighter input)
• 1 Unit Battery Pack (shown in packaging)
• 1 Unit Oxygen Cannula (transparent tube attached to the device)
• 1 Unit Power Cable (connected to the adapter)
• 1 Unit Original Product Box

No missing parts have been detected; the device is a ready-to-use set for both home and car use.

Label and Barcode Information

The following technical codes can be read from the labels on the original box:

• REF / Model: Spirit-3
• Standard Code: CE 0123 (European health standards compliance certificate)
• Barcode Numbers: 30028533 and below it, codes 000010164710/29 are present.

Originality and Documents

Upon examination of the product’s material quality, screen fonts, bag stitching, and box prints, it has been assessed as a 100% original Yuwell product. No warranty certificate or invoice document has been physically observed in the visuals.

Potential Fault Risk

The device’s external appearance is clean, its screen is intact, and its warning systems are active (the ‘No Breath Detected’ warning indicates the sensor is functional). No crushing, peeling, or rusting is visible on the cables or connector ends. Having been used for only 126 hours indicates that the device’s motor life is still in its early stages. Based on the visual data, no physical indication of a fault risk in the near future has been found.
