Medwelt Oxygen Concentrator Analysis Report

Overview and Device Description

The product shown in the images is a Medwelt brand oxygen concentrator that produces enriched oxygen from ambient air for users requiring respiratory support. The device features a vertical, wheeled design suitable for home use. Its primary function is to separate nitrogen from the air, providing continuous and high-purity oxygen to the user.

Brand and Model Information

A clear red Medwelt brand logo is visible on the front of the device. Based on this information, the product’s brand is definitively Medwelt. However, examination of the images did not reveal the specific model number or name of the device.

General Status and Condition

The overall condition of the device is assessed as used. The 10404.2 hours of usage displayed on the digital screen of the front panel indicate that the device has been actively used. Despite this, the device’s casing appears quite clean and well-maintained. No significant physical deformation has been observed. Its general condition is good relative to its hours of use.

Physical and Mechanical Evaluation

• Casing and Exterior Surface: No cracks, breaks, or significant discoloration have been detected on the device’s white plastic casing. Surfaces are generally clean, but upon detailed inspection, minimal, insignificant scratches due to use may be present.
• Control Panel and Buttons: The power button, timer setting buttons, and digital display on the front panel are physically in sound condition.
• Mechanical Parts: Mechanical parts such as the flowmeter for adjusting oxygen flow and the humidifier water tank slot show no visible damage or functional issues.

Screen and Electronic Components Analysis

The device’s electronic components are in working order. The images show the device plugged in and the front panel screen active. Screen analysis reveals the following details:

• Operating Hours (Counts – hours): The counter showing the device’s total operating time reads 10404.2 hours.
• Timer (Timing – minutes): There is a timer function that allows the device to operate for a set period and then automatically shut off. This duration can be adjusted using the plus (+) and minus (-) buttons. The “1-99min” indication on the panel shows that the timer can be set between 1 and 99 minutes.
• Power Button: A button labeled “POWER” with an on/off function is present.

Accessories and Connection Ports

The following accessories and parts have been identified with the device in the images:

• Power Cable: A standard power cable is connected to the device and plugged into an outlet. There is no visible crushing, wear, or damage on the cable.
• Humidifier Reservoir: A humidifier water bottle is installed in the transparent compartment on the front of the device.
• Oxygen Outlet Port: An output port labeled “OXYGEN OUTLET” on the front panel, where the oxygen cannula is attached, is present.

Accessories such as an oxygen mask or nasal cannula, which are necessary for the device’s operation, are not present in the images.

Label and Technical Information

Labels containing warnings in Turkish and English are located on the top of the device. These labels specify safety precautions to be observed during device use (e.g., keeping away from fire, intervention only by authorized service, use of original parts, etc.). However, detailed technical information such as serial number, REF code, lot number, or year of manufacture cannot be obtained from the images.

Potential Risk Assessment

Although the device’s physical condition is generally good, the usage time exceeding 10,000 hours highlights the importance of periodic maintenance and filter checks. Visually, no signs of malfunction or significant wear (such as crushed cables, cracked casing, rust, etc.) that would pose a potential risk have been observed on the device. The product’s current condition indicates that it should operate correctly.
