Respirox 7F-5B Oxygen Concentrator Analysis Report

Product Overview

The device shown in the visuals is an oxygen concentrator used for medical purposes. The primary function of the device is to produce concentrated oxygen using ambient air and deliver it to patients requiring respiratory support. The brand and model of the product have been clearly identified. Along with the device, a water humidifier reservoir and some small accessories are located in its top-lidded compartment.

Brand and Model

Upon inspection of the device’s front surface, its brand is clearly read as Respirox and its model as 7F-5B. The logo and model designation support the device’s unique appearance.

Quantity and Content Information

The products in the visual are as follows:

• 1 unit Respirox 7F-5B Oxygen Concentrator
• 1 unit water humidifier reservoir (attached to the device)
• Inside the top compartment, there are some items visible in a sealed bag, likely parts such as a nasal cannula or tubing, along with some papers presumed to be a user manual.

Overall Condition

The general condition of the device is assessed as used. Its white plastic casing shows occasional yellowing, small stains, and scratches. This suggests that the device has been used for some time or has been affected by the conditions of its storage environment. However, its overall condition indicates no major damage that would impede its operation.

Physical Deformity Inspection

Upon examination of the product’s physical condition, the following details were observed:

• Casing: A general yellowing and discoloration are noticeable on the device’s white plastic casing. Minor scratches and dirt are present on the top cover section and side surfaces. No serious cracks, fractures, or dents are present.
• Humidifier Reservoir Section: The transparent plastic lid is clean and intact. The humidifier reservoir inside also appears physically sound.

Mechanical and Electronic Components

The mechanical and electronic components of the device are visually as follows:

• Flow Meter: Located on the right side, there is a manual adjustment knob and indicator used to set oxygen flow between 0 and 5 liters per minute (L/min). The indicator glass is intact.
• Control Panel: On the top part of the device, there is a digital screen, one POWER button, and (+) and (-) buttons used to set the timer. No breaks or missing parts are visible on the buttons.
• Display: The digital display shows the phrases COUNTS (hours) and TIMING (minutes). This indicates that the device records total operating hours and can be timed for a specific duration. However, since the screen is off, no error codes or operational information can be seen.
• Output Port: On the front surface, there is an oxygen output port marked as OXYGEN OUTLET.
• Top Storage Compartment: On the top part of the device, there is a lidded compartment where accessories can be placed. The hinges and lid of this compartment appear sturdy.

Label and Certification Information

Labels containing technical details such as serial number, production year, and REF code, located on the back or bottom of the device, are not visible in the visuals. Only descriptive texts such as brand, model, and “OXYGEN CONCENTRATOR” are present on the front.

Accessories

The accessories included with the device are partially visible in the visual:

• Humidifier Reservoir: The transparent reservoir and black lid, which humidify oxygen before delivery to the patient, are present.
• Other Accessories: Inside the top storage compartment, there is an unopened bag containing a medical item such as tubing or a cannula, and one small black-colored piece. Additionally, some printed documents (likely a user manual) are also in this compartment.

Potential Malfunction Risk and Evaluation

No obvious malfunction (such as cracks, fractures, burn marks, error codes on the screen, etc.) belonging to the device is visible in the visuals. The discoloration and small scratches on the casing are purely cosmetic defects and may not directly affect the device’s operation. However, due to the device being used and the total operating hours being unknown, a clear comment cannot be made regarding the performance of its electronic or mechanical components. Based on its visible physical condition, the device’s condition is good, and no impediment to its operation has been detected.
