Respirox Oxygen Concentrator Analysis Report

Device Identification

The device shown in the visuals is an Oxygen Concentrator that provides medical respiratory support. The device takes ambient air, separates nitrogen, and provides high-concentration oxygen to the patient. It is a stationary type (home-use) device, designed to be movable on its wheels.

Brand and Model

At the bottom of the device’s front panel, the Respirox brand logo and ® (registered) trademark are clearly visible. The scale on the flowmeter is graded up to 5 L/min, indicating that the device is a 5-liter capacity model. Since a specific alphanumeric code indicating the model name (e.g., SZ-5BW, etc.) is not clearly legible on the device, model information has not been specified.

General Condition and Originality

The device is in used condition. The “Respirox” logo and typography appear consistent with standard Respirox devices known in the Turkish market; no significant visual inconsistency suggesting a lack of originality has been detected.

Usage Areas

This device is used for home-based treatment of patients requiring continuous or intermittent oxygen therapy due to conditions such as COPD (Chronic Obstructive Pulmonary Disease), pulmonary fibrosis, and respiratory failure. It is suitable for use in healthcare facilities or home care settings. It is designed for patients requiring 0-5 Liters/minute oxygen flow.

Physical Deformation and Cosmetic Condition

• Front Panel: There are prominent abrasion marks and scratches on the front surface of the device, especially on the left-central parts and around the screen.
• Screen Surface: Numerous hairline scratches are visible on the screen’s protective plastic, but the text on the screen is still legible.
• Handle: Dirt or minor wear marks due to usage are noticeable around the top handle.
• Body Color: The device has a gray body and a black base. Regional discoloration or dirt is present in the gray tone.

Mechanical and Electronic Component Examination

Mechanical and electronic details based on visual inspection are as follows:

• Flowmeter: The mechanical flowmeter tube located on the front left appears intact. The ball level indicator inside is at the bottom (indicating that the device was not running when the picture was taken or the flow was off).
• Wheels: Movable black wheels are present at the bottom of the device. No breakage has been detected in the visuals.
• Control Panel:
  • 1 On/Off switch (Rocker Switch).
  • 2 round push buttons (likely for time or settings).
  • No physical missing parts or depressions are visible on the buttons.
• Screen: The blue-backlit LCD screen appears to be functional (indicating the device is connected to power).

Screen Analysis and Operating Data

The LCD screen, visible in detail in the second visual, displays the following technical data:

• S.Times : 0000678: (Session Times) This could be a value for the current session or a similar time counter.
• O.P. MPa : 0.078: (Operating Pressure) This indicates an operating pressure of 0.078 MPa. This shows that the device’s compressor is generating pressure.
• O.Time : 0000:05: (Operating Time) This indicates that the current operation has been ongoing for 5 minutes.
• Acc.Time : 0020942: (Accumulated Time) This is the total accumulated operating time. It indicates that the device has been used for a total of 20,942 units (usually hours). This value demonstrates that the device has been in use for an extended period.

Panel Warning Lights

A series of LED indicators are located below the screen:

• P.O. (Power On): The green light is on. This indicates that the device is connected to power and turned on.
• Other lights (P.F., L.P., H.P.(T), L.O2, H.O2) are currently off. This means that no immediate fault warning (low pressure, low oxygen, etc.) is being indicated.

Label and Warning Information

The device’s front panel contains the following vital warnings in both Turkish and English:

• Reading Warning: Please read the user manual before operating the machine.
• Authorization Warning: Do not open the machine’s interior except by professional personnel.
• Maintenance Warning: It is recommended to clean the dust filter monthly and replace the air inlet filter monthly.
• Performance Information: Oxygen concentration is 93% ± 3%.
• Safety (Fire): Do not smoke or have open flames in the vicinity.
• Safety (Oil): Do not use oil or grease. (Flammable when in contact with oxygen).

Accessories and Missing Items

• Humidifier Bottle: There is a niche for a humidifier bottle and a black rubber retaining band on the front of the device. However, the humidifier water bottle is not attached to the device; it is missing.
• Oxygen Cannula/Mask: No hose, cannula, or mask is visible in the visuals.
• Power Cable: Although a black cable is visible in the background, considering the device is operational (screen is on), the power cable is present and connected.

Usage Duration

Considering the Acc.Time: 0020942 display on the screen, the device’s counter shows 20,942 units. In oxygen concentrators, this is usually in “hours”. If it is hours, this is a very high usage duration (approximately 2.4 years of continuous operation). The device’s overall worn cosmetic condition also corroborates this high usage duration.

Potential Failure Risk and Assessment

The device appears to be in operational (Power On) condition and is generating a pressure value on the screen. No red “Service” or “Alarm” light is illuminated. However, the following points should be considered:

• High Operating Hours: A counter value over 20,000 indicates that the compressor and filters (molecular sieves) may have largely completed their lifespan or are in need of maintenance.
• Cosmetic Wear: Extensive scratches on the casing suggest that the device has been subjected to numerous impacts or abrasions during transport or use.

Although the device appears functional at present, due to its heavy usage, it may require detailed technical maintenance and oxygen purity measurement.
