Oxygen Concentrator Visual Analysis Report

Device Detection and Identification

The device in the image is a vertically designed oxygen concentrator used for medical purposes, which separates oxygen from ambient air and delivers it to the patient. The general structure of the device, including the humidifier bottle chamber on its front face, the flow meter indicator, and the output ports, indicates that it is a standard home-use respiratory support device. The product has a white hard plastic casing and is entirely wrapped in a transparent protective stretch film in the image.

Areas of Use

This device is used to provide long-term oxygen therapy for patients with chronic lung conditions such as COPD, asthma, pulmonary fibrosis, or those with low blood oxygen saturation. It is designed to deliver oxygen support of the required purity to patients in home care services, hospitals, or clinics. Respiratory support is provided via a cannula or mask attached to the output port on the device.

Quantity Information

The parts identified based on visual analysis are as follows:

• 1 unit Oxygen Concentrator (Main Unit)
• 1 unit Power Cable (Coiled on the device)
• 1 unit Humidifier Bottle (Attached to the front chamber of the device)

General Condition and State

The product, as seen in the image, is tightly wrapped in a completely transparent packaging (stretch film). This wrapping suggests that the product is being prepared for transport or storage, or is intended to be protected from dust. The device casing generally appears clean and its integrity is preserved. No yellowing or significant signs of dirt are noticeable on the product’s white plastic body.

Physical Deformation Inspection

Upon inspection through the transparent protective film, no significant dents, breaks, cracks, or deep scratches were detected on the device’s outer casing. The corner lines appear regular. However, due to the reflections and creases of the protective packaging, the 100% smoothness of the surface cannot be definitively confirmed, but there is no visible major damage.

Mechanical Components

The condition of the mechanical parts located on the front panel of the device is as follows:

• Flow Adjustment Knob (Flowmeter Knob): The circular adjustment knob located in the upper right corner is in place and appears physically sound.
• Humidifier Chamber Lid: The transparent lidded section in the front-middle area is intact, and no breaks are seen in the hinges or securing parts.
• Oxygen Output Port: The metal tip (oxygen outlet) located on the left side is intact and in place.

Electronic Components and Screen Analysis

There is a black control panel or screen area on the top part of the device. However, since the device is turned off and covered with a protective film, it is not possible to obtain information from the visual about the screen’s operational status, whether there are pixel errors, or any warning messages on the screen. Only the physical presence of the screen panel can be stated.

Accessories

The accessories identified on the device have been examined in detail:

• Power Cable: A black power cable, coiled and packaged with the device, is located on the top part of the device. No visual signs of crushing or breakage were noticed on the cable.
• Humidifier Bottle: A transparent water container (humidifier bottle) with a black lid is present, placed in the special chamber on the front face of the device. The installation of the bottle appears complete.

Label and Text Information

The texts readable on the front face of the device are as follows:

• OXYGEN CONCENTRATOR: The main inscription on the lower front body, indicating what the device is.
• Oxygen outlet: The informative text above the metal oxygen output tip on the left side.
• L/min O2 and Flowmeter: Technical inscriptions located next to and below the flow meter tube on the right side.
• Graduated scale lines from 0 to 5 (estimated) are visible on the flow meter tube.

Potential Failure Risk

During the visual inspection, no critical risk factors threatening the device’s condition, such as rust, traces of liquid contact, casing cracks, or cable deformations, were encountered. The fact that the product is wrapped in protective film indicates that it is protected against external factors, which positively affects the device’s reliability. There are no visible serious risk factors.
