Medwelt 7F-5B Oxygen Concentrator Analysis Report

Device Identification and Product Description

The examined image shows a closed package belonging to an oxygen concentrator, which is a medical device. The image does not show the device itself, but its original packaging and the visual/written information on this packaging. As understood from the visual on the box, the product has a design with wheels, a vertical form, and a digital screen and flow meter on its front panel. Additionally, the phrase “With nebulizing function” is located at the bottom of the box, indicating that the device also has a nebulizer function.

Brand and Model

Upon examination of the logos, model numbers, and labels on the box, the brand and model of the product have been definitively identified.

• Brand: Medwelt
• Model: 7F-5B
• Manufacturer: Jiangsu Yuyue Medical Equipment & Supply Co., Ltd. (Manufacturer indicated on the box).

Authenticity and Box Contents

The product is contained within a professional package with brand-specific prints, conforming to labeling standards. The presence of the Medwelt logo, model number, safety icons, and a barcoded tracking label indicates that the product is original. The drawings and diagrams on the box align with brand standards.

Quantity Information

The image shows a single (1 unit) closed package. It is understood that the box contains 1 unit of the 7F-5B model oxygen concentrator.

Areas of Use

This device is used to separate oxygen from ambient air and provide high-concentration oxygen support to patients. It is generally designed for long-term oxygen therapy at home or in clinical settings for patients suffering from COPD, asthma, lung diseases, or respiratory failure. Furthermore, its “nebulizing function” allows medications to be vaporized and inhaled through the respiratory tract (nebulizer therapy).

General Condition and Physical Deformation

The product should be evaluated as being in closed box (new) status. Upon examination of the package:

• The box integrity is preserved, and it is sealed with packing tape.
• On the cardboard surface, minimal deformations are observed due to shelf life or transport, including a slight dent on the left vertical edge of the cardboard, but these are not severe enough to damage the box contents.
• There are no tears, serious holes, or water damage on the outer packaging.

Technical Data and Label Information

The technical data obtained from the white barcoded label on the side surface of the box and the prints on the box are as follows:

• Product Name: Oxygen Concentrator (Oxygen Concentrator)
• REF Code: 7F-5B
• Serial Number (SN): 2406180696
• LOT Number: JR240418
• Power Supply: 220V~ 50Hz
• Input Power: 400VA

Manufacturing Year and Date Information

According to both the print and label information on the box, the date details are as follows:

• Manufacturing Date (MFG): 23.06.2024 (2024/06/23)
• Expiration/Validity Date (According to the symbol on the box): 22.06.2029

Mechanical and Electronic Components

As the device is in a closed package, the mechanical and electronic components could not be directly observed. However, as it is a “new/unused” product, its wheels, screen, compressor, filters, and outer casing should be assumed to be in factory-new condition. The warning signs on the box (Fragile, Keep dry, Handle upright) confirm that the product contains sensitive electronic and mechanical parts.

Battery Status

This model (7F-5B), as understood from the “220V~ 50Hz” indication on its label, operates with mains electricity. There is no data in the visual or label information indicating the presence of an internal battery.

Potential Malfunction Risk

Upon examination of the outer packaging’s condition, there is no evidence that the device sustained a serious impact during transportation or storage. The box corners and surfaces appear intact. Due to the product’s recent manufacturing date (2024), there is no risk of material fatigue or wear and tear. However, as these are sensitive medical devices, authorized service installation and functional tests are recommended before first use.
