Yuwell 8F-5A Oxygen Concentrator Analysis Report

Device Identification and Description

As a result of a detailed examination of the visuals, the analyzed device has been identified as a medically used, electric-powered oxygen concentrator. The device is a wheeled and portable type of medical equipment designed to produce high-purity oxygen by taking ambient air and separating nitrogen.

Brand and Model Information

Based on the prominent logos and inscriptions on the front face, rear label, and top panel of the device, the brand and model information is unequivocally as follows:

• Brand: Yuwell
• Model: 8F-5A
• Device Type: Oxygen Concentrator (Oksijen Konsantratörü)

On the product label, it is clearly stated that the manufacturer is “Jiangsu Yuyue Medical Equipment & Supply Co., Ltd.” and the Turkish importer is “Respitek Sağlık Ürünleri”.

Originality Assessment

The print quality of the labels on the device, the logo placement, the complete presence of CE certification marks (CE0123), and authorized distributor information indicate that the product is an original Yuwell production. Variable data such as the serial number and manufacturing date on the label are subsequently processed, which is typical of a factory label structure.

Areas of Use

This device is designed for patients with COPD, respiratory failure, or those who require continuous oxygen therapy. This model, suitable for home use, filters ambient air and provides high-concentration oxygen to the patient via a cannula mask. It offers oxygen support at a flow rate of 1 to 5 liters/minute.

General Condition and Physical State

The outer casing of the device is made of white hard plastic, and the upper control panel is made of black material. Upon examining its general condition:

• Casing: No visible cracks, deep scratches, or breaks have been detected on the white plastic body. The integrity of the body is maintained.
• Cleanliness: There is significant dust accumulation on the device, particularly on the black upper control panel, in its crevices and protrusions. Dusting/lint is also observed on the rear filter cover grilles and at the wheel connection points. It appears that the device has generally been stored in a dusty environment.
• Panel: The flow meter (flow rate indicator) and screen glass on the front face are intact.

Quantity Information

The visuals show 1 (one) main oxygen concentrator unit and 1 (one) package of transparently packaged accessory set placed in front of the device.

Mechanical and Electronic Component Examination

The technical analysis based on the visible components of the device is as follows:

• Flow Control: On the front panel, there is a manual flow adjustment knob (Flowrate) and a ball-type indicator tube directly above it. The indicator shows values between 0 and 5 L/min. The mechanism appears visually intact.
• Screen and Buttons: On the top panel, there is an LCD screen and buttons for “Timing”, “Counts”, on/off, and menu. Although it’s unknown whether there are pixel errors since the screen is off, there are no physical breaks in the screen glass.
• Wheels: At the bottom of the device, there are black wheels, understood to have swivel heads. The wheel visible in the visuals is intact and in place.
• Filter Access: The cover on the rear, bearing the inscription “Pull out to replace the filter” (Filtreyi değiştirmek için çekin), is intact.

Accessories

Next to the device, there is an accessory set in a transparent zip-lock bag, which appears to be unopened. Inside the bag:

• A transparent silicone oxygen hose/cannula is visible.
• A user manual or informational paper is included in the package.
• Since the package is unopened, the product appears to maintain its sterility or cleanliness.

Note: The device’s power cable might be wrapped at the rear bottom part or integrated into the body in the visual, but its end and plug connection are not clearly displayed openly in the visuals. A cable outlet slot is present at the rear.

Label Information and Technical Data

The data read from the technical label on the rear of the device are as follows:

• Power Supply: AC220V ±10%, 50Hz
• Input Power: 400VA
• Serial Number (SN): 23110800017
• Manufacturing Date: 30/11/2023 (The device appears to have been manufactured at the end of November 2023, making it a relatively new device.)
• Oxygen Purity: Provides oxygen purity of 95.5% ~ 87% at a flow rate of 1-5L/min.

Additionally, there is a Turkish warning label on the rear cover. This label includes safety warnings such as “Fire Risk,” the necessity of not smoking, and keeping it away from textile products (bedding, etc.).

Battery Status

This type (8F-5A) of oxygen concentrator operates with mains electricity (AC 220V). There is no indication of an internal battery or a battery compartment in the visuals or on the label information. It operates connected to an external power source.

Potential Malfunction Risk and Assessment

The visuals show no breaks, severed cables, dents, or signs of oxidation/rusting that would impede the device’s operation. The only noticeable aspect is the dust accumulation on the device’s surface; this may necessitate checking the filters. The device’s manufacturing date being late 2023 suggests that it is at the beginning of its service life, implying minimal mechanical fatigue. Its physical condition is good.
