RespiroX 7F-5B Oxygen Concentrator Analysis Report

Overview and Device Description

The device shown in the visuals is one RespiroX brand, 7F-5B model oxygen concentrator. This device is a respiratory apparatus used to produce concentrated oxygen suitable for medical use by separating nitrogen from ambient air. The device is generally observed to be upright, wheeled, and portable. A transparent humidifier water container is included with the device.

• Brand: RespiroX
• Model: 7F-5B
• Product Type: Oxygen Concentrator
• Quantity in Visual: 1 Oxygen Concentrator, 1 Humidifier Container

Application Area and Purpose

Oxygen concentrators are designed for patients suffering from respiratory failure or requiring supplemental oxygen support. The device continuously produces oxygen with 93% (±3) purity using ambient air, supporting the patient’s respiration. The “FLOW METER” section in the visual indicates that the oxygen flow rate can be adjusted between 0 and 5 liters per minute. This feature indicates that the device can be used for patients with different needs.

General Condition and State

The general condition of the device is assessed as “used”. No significant cracks, fractures, or major discoloration have been observed on its white plastic casing. However, there are significant peeling, air bubbles, and wear, especially on the screen protector film of the control panel. This situation is a clear indication that the device has been used previously. Apart from this, the device’s casing generally appears clean and well-maintained.

Physical and Mechanical Components Analysis

The physical and mechanical components of the device have been carefully examined. No significant deformation indicating a functional defect has been detected.

• Casing: The outer casing of the device is made of white plastic. There are no major cracks, dents, or stains on it. It is observed to be standing on a wooden floor, and it is understood that there are wheels or feet at its base to facilitate transport.
• Control Panel: The upper part of the device features a digital screen and control buttons. The largely peeled and deformed protective film on the panel constitutes an aesthetic flaw. The panel includes a “POWER” on/off button, “+” and “-” buttons for timer settings, an alarm, and an “I/O” button.
• Flow Meter: On the right side, there is a rotary knob for adjusting oxygen flow in liters per minute (L/min) and a transparent measurement tube. The ball inside the tube is at the lowest level (0), indicating that the device is not operating.
• Humidifier Reservoir: In the front-center part of the device, behind a transparent protective cover, there is a humidifier water container. The cover is in place and appears physically intact.
• Oxygen Outlet: To the left of the humidifier reservoir, there is an outlet port where the cannula used to deliver oxygen to the patient would be attached.

Screen and Electronic Components

The device’s digital screen and electronic components have been analyzed to the extent permitted by the visuals. Due to the severe deformation of the protective film on the screen, not all information on the screen can be read clearly. However, indicators such as “COUNTS (hours)” (total operating hours) and “TIMING (minutes)” (timer) are discernible. This indicates that the total usage time of the device is recorded, but this duration cannot be determined with the current image quality. No error codes or warning lights are active in the visual.

Accessories and Cables

The basic accessories and connections of the device are visible in the visual.

• Humidifier Container: There is one transparent humidifier container attached to the device and empty.
• Power Cable: A white power cable extends from the back of the device. No visible crushing or damage has been detected in the physical condition of the cable.
• Missing Accessories: Accessories necessary for patient use, such as an oxygen cannula (nasal tubing) or a mask, are not present in the visuals.

Label and Text Analysis

All legible texts and labels on the device are listed below. Detailed technical labels such as serial number, lot number, or REF code are not present in the visuals.

• Brand/Model: RespiroX, 7F-5B
• Device Type: OXYGEN CONCENTRATOR
• Panel Texts: POWER, OXYGEN OUTLET, FLOW METER, COUNTS (hours), TIMING (minutes)

Potential Malfunction Risk Assessment

There is no direct evidence in the visuals indicating an existing or functional malfunction. The device’s outer casing and mechanical parts are in good condition. However, the excessively worn screen protector on the control panel may suggest that the device has been heavily used. While this situation might suggest a potential future need for maintenance of electronic components or internal parts such as the compressor, this is merely an observation-based comment and does not signify an existing malfunction. Generally, the device does not have any obvious physical damage that would impede its operation, and its condition can be considered normal for a used device.
