Oxygen Concentrator Visual Analysis Report

Device Detection and Identification

The product in the visual is an Oxygen Concentrator designed to provide medical respiratory support. The device is a fixed, upright model designed with wheels (as understood from the base structure) and suitable for home use. The primary function of the unit is to take in ambient air, separate nitrogen, and deliver high-concentration oxygen to the patient.

Brand and Model Information

On the front of the device, at the bottom, there is the inscription OXYGEN CONCENTRATOR in capital letters, and immediately above it, a blue-green toned logo resembling a globe. However, a specific brand name belonging to the manufacturer (such as Philips, Devilbiss, etc.) or a distinguishing model number (like JAY-5, 7F-5) is not visually legible on the device casing. Therefore, the product has been identified by the generic name Oxygen Concentrator as it appears in the visual.

Areas of Use

This device is used for patients experiencing respiratory failure such as COPD, asthma, pulmonary fibrosis, or those with low blood oxygen saturation (hypoxemia), to receive long-term oxygen therapy (LTOT) in a home environment. It is one of the essential life support units in home care processes for patients discharged from hospitals.

Quantity Information

The visuals show 1 unit of oxygen concentrator device. No spare parts, masks, or additional accessories are present in the visual.

General Condition and Physical State

The outer casing of the device is made of cream (beige) and gray hard plastic. Its overall physical integrity appears to be preserved. No large visible cracks or breaks have been detected on the casing. However, a slight discoloration (tendency to yellow) is observed on the plastic surface, which may indicate that the device has been used for a certain period or exposed to sunlight. Although the device’s general appearance is clean, signs of use are present.

Condition of Mechanical Parts and Accessories

As a result of the visual analysis, the following details regarding mechanical components and accessories have been identified:

• Humidifier Bottle Missing: In the gray body section in the middle of the device, there is a designated slot and a fixing strap for the water container (humidifier bottle) that moisturizes the oxygen. However, this bottle is absent in the visual. This part needs to be acquired for use.
• Flowmeter: On the right front panel, there is a mechanical flowmeter tube and a black adjustment knob for setting the oxygen flow rate (Liters/Minute). The tube appears intact.
• Air Filter Cover: The rear or side filter covers of the device cannot be clearly assessed from this angle.

Electronic Components and Screen Analysis

The device’s top control panel houses electronic components:

• LCD Screen: In the upper left corner, there is an LCD information screen, presumed to be blue-backlit. Since the device is off, information such as operating hours or error codes cannot be read on the screen.
• Control Buttons: Below the screen, buttons for “Timing +” (Increase Timing), “Timing -” (Decrease Timing), and “Back Light” functions are visible. The surface of the buttons is intact.
• Power Switch: On the right side, there is a black “POWER” labeled on/off (rocker) switch.
• Status LEDs: On the panel, there are warning lights labeled with abbreviations such as L.O., H.O., H.T. (likely meaning Low Oxygen, High Oxygen, High Temperature), indicating the device’s operating status.

Label and Warning Information

On the top panel of the device, there is an information text titled “CAUTION” containing warnings that the user should heed. As far as can be read from the visual, the following technical information and warnings are present:

• Oxygen Purity: The text states that the oxygen purity is 93% ± 3%. This indicates that the device aims for medical standard oxygen production.
• Filter Maintenance: It is stated that the inlet air filter should be cleaned every 100 hours.
• Safety: Warnings against smoking (NO SMOKING) and approaching with open flames are included.
• Oil Warning: It is explicitly stated that no oil or grease should be used (NO OIL OR GREASE) (as oil reacts with oxygen and poses a combustion risk).

Existing Faults and Risk Assessment

There is no concrete evidence in the visual indicating that the device is “faulty” (e.g., service light on, broken screen, etc.). However:

• The absence of the humidifier bottle (water container) prevents the device from being connected to a patient and used as is. This part must be completed before use.
• Since the device is not shown plugged in and operational, no comments can be made based on the visual regarding the condition of the oxygen sensor, compressor performance, and the lifespan of the molecular sieves (zeolite).
• Based on its external appearance, it gives the impression of a second-hand product in clean condition.
