Oxygen Concentrator M50 Analysis Report

Product Description and Intended Use

The device shown in the visuals is an Oxygen Concentrator model. The label on the front of the device displays the expression “M50,” which is understood to be the model code. Oxygen concentrators are medical devices that take in ambient air, separate the nitrogen from it, produce high-purity oxygen, and deliver it to patients who require respiratory support. From the visuals, it is understood that this product is designed for use at home or in healthcare facilities.

A total of 1 oxygen concentrator and 1 transparent tube attached to the device, connected to a flow meter, have been observed.

General Condition and Physical Assessment

The general condition of the device is assessed as used. There is general dust and dirt on its blue casing. The device’s condition, while not exhibiting major damage that would prevent its operation, does have cosmetic imperfections. No original box or packaging is visible in the images.

• Scratches and Abrasions: White, superficial scratches and scuff marks are present on the upper part of the device, next to the carrying handle, and on the side surfaces towards the lower sections.
• Color Change: No significant fading or discoloration of the device’s color has been observed.
• Dirt and Dust: The general surface of the product and its recessed parts, such as the wheels, are noticeably dusty.

Mechanical and Electronic Component Examination

The mechanical and electronic components of the device have been visually inspected.

• Mechanical Components: The wheels located at the bottom of the device appear to be intact but dusty. The integrated carrying handle on the top section has a physically robust appearance. The on/off switch (rocker switch) and the flow meter valve used to adjust oxygen flow, located on the front panel, are in place. The transparent tube of the flow meter appears unbroken and intact.
• Electronic Components: A digital screen area is present on the front panel, but since the device is off, it cannot be determined whether the screen is functional or displaying any information. Next to the screen, there are two LED indicator light positions: one for power and one with a book/warning symbol. The on/off switch appears mechanically sound.

Accessories and Equipment

In the visuals, one transparent tube is seen attached to the oxygen outlet of the device. This tube is connected to a cylindrical transparent flow meter with numbers (from 1 to 5) and lines indicating flow levels. Apart from this setup, the device’s power cable, extension tubes, cannulas, or other additional accessories are not present in the visuals.

Label and Warning Information

A large, black warning label is present on the front panel of the device. The information on this label is entirely in English and includes the following warnings:

• Headings: “No Smoking” and “No Fire” symbols are present, along with the “Attention” heading.
• Warning Items:
  • Do not smoke or use fire while the oxygen concentrator is operating.
  • Do not raise the flow meter ball above the red line.
  • Do not use the device in high humidity environments.
  • Do not move the device or cover it while it is operating.
  • Do not extend the power cord.
  • Electrical hazards. Do not disassemble the device without permission.
  • Do not use oil or grease.
• Model Code: A separate black label displaying “M50” is located below the warning label on the front panel.

Information such as the device’s serial number, lot number, REF code, or year of manufacture could not be found in the visuals.

Potential Risk Assessment

No visible serious damage such as breaks, cracks, or dents is present on the device. However, the dust and dirt on the surface may indicate that the device has not been used for a long time or has been stored. This situation carries the potential that the device’s internal filters and mechanism may require maintenance. Superficial scratches, which are cosmetic imperfections, do not appear to affect the device’s functionality. Generally, based on visual evidence, there is no serious indication that the device’s physical condition poses a potential risk of malfunction, but it is recommended that it be checked and maintained by an authorized technician before use.
