Yuwell 8F-5A Oxygen Concentrator Analysis Report

Device Identification

The device in the analyzed visuals is an electrical oxygen production device falling into the category of medical products. Upon examining its visual features, structure, and components (humidifier bottle, flow meter, connection tubes), it has been identified that this device is a home-use Oxygen Concentrator.

Brand and Model

As a result of detailed analysis of the device’s front panel and the inscriptions on it, the following identification information has been confirmed:

• Brand: Yuwell
• Model: 8F-5A

This information can be clearly read on the front face of the device, just below the screen and on the lower central part of the body. The font of the brand logo and model number matches the characters in the product’s original catalog images.

Originality

Upon examining the font of the logo, print quality, button layout, screen structure, and overall casing craftsmanship on the product, it is assessed that the product is an original Yuwell production. The characteristic font of the “Yuwell” inscription and its integration into the body reflect original product standards.

Areas of Use

The Yuwell 8F-5A oxygen concentrator is a medical device that takes ambient air, separates nitrogen gas from it, and provides high-purity oxygen to the user. Its primary areas of use are:

• Treatment of Chronic Obstructive Pulmonary Disease (COPD).
• Continuous or intermittent oxygen support for home care patients.
• Treatment of respiratory patients experiencing low oxygen saturation.
• Compatibility: The device has an outlet compatible with standard nasal cannulas or oxygen masks (only an interim connection tube is present in the visual).

Quantity Information

The visuals show a total of 1 unit of the main device and 1 unit of a humidifier water tank integrated/attached to this unit.

General Condition and Physical State

The device is in “used” condition. While the overall casing integrity appears sound, there are cosmetic signs of use. No cracks or breaks have been detected in the body plastics.

Physical Deformations

The following deformations are noticeable during inspections of the product’s outer surface:

• Front Body: On the device’s white front panel, particularly to the left of the “L/min O2” inscription and in the lower parts, there are grey friction marks, stains, and dirt.
• Top Panel: Dust accumulation has been observed around the black control panel and the handle. Additionally, dirt is present in the panel joints and gaps.
• General Cleaning: It is understood that the device requires detailed external cleaning.

Mechanical and Electronic Components

Technical observations based on visual inspection are as follows:

• Flow Meter: The mechanical flow meter tube on the front face and the indicator ball inside appear intact. The scale ranges from 0 to 5 (5 liters of oxygen capacity per minute).
• Flow Adjustment Knob: The black manual adjustment wheel below the “Flowrate” inscription is physically intact and in place.
• Buttons: No wear or fading is observed on the “+”, “-“, and “Power” symbol buttons located on the device’s top panel.
• Screen: The LCD panel on the upper part of the device is physically intact (no breaks), but pixel errors or electronic functionality could not be tested from the visual as the device is in the off position.

Accessories and Connections

The components attached to and accompanying the device in the visuals are:

• Humidifier Bottle: A built-in humidifier bottle (water container) is present in the device’s rear compartment. The bottle is transparent and secured with a grey holder. The cap structure appears sound.
• Connection Tube: A short, transparent silicone connection tube leading from the device’s “OXYGEN OUTLET” to the humidifier bottle is present. No bends or breaks are observed in the tube.
• Missing Items: The long oxygen tube (nasal cannula) or mask, which would deliver oxygen to the patient, is not present in the visual. The user of the device will need to procure these consumables.

Label Information and Interface

The inscriptions and labels on the device provide information about its technical specifications:

• 8F-5A: This is the device’s model code.
• L/min O2: Indicates that the flow meter shows oxygen flow in liters per minute.
• TIMING / COUNTS: Shows that the screen has timer setting and total operating hours counter (COUNTS) features. This is important for tracking how long the device has been used.
• Flowrate +/-: Indicates the direction of the manual wheel used to adjust the flow rate.
• OXYGEN OUTLET: Marks the clean oxygen output port.

Dimensions and Portability

Although there is no reference scale in the visual, the product’s design and handle (Image 1, top part) indicate that it is a portable wheeled (though the wheels are not fully within the frame, they are standard in these models structurally) and floor-standing type model for home use.

Documentation

No invoice, warranty certificate, or user manual is present in the visuals. Whether its warranty is still valid cannot be determined from the visual data.

Potential Failure Risk

There is no serious damage (deep cracks, rust, broken parts) visible on the device. However, dust accumulation on the top panel and near the air intake grilles indicates that the device’s filters should be checked and cleaned. If not maintained, this could lead to a risk of overheating. Its physical integrity has been preserved in terms of condition.
