RespiroX Oxygen Concentrator Analysis Report

Overview and Product Description

The device shown in the images is a RespiroX brand oxygen concentrator. It is a medical device designed to separate oxygen from ambient air and deliver high-concentration oxygen to the user’s respiratory system. Its front panel features a digital screen, a power button, time adjustment keys, a flow meter, and a humidifier reservoir. The overall structure of the device and its labels give the impression of an original product.

• Device Type: Oxygen Concentrator
• Brand: RespiroX
• Quantity: 1 main unit and 1 humidifier bottle

Condition and Assessment

The device is a used product. While no significant deformations such as serious cracks, fractures, or dents are observed on its casing, there are noticeable dirt and stains, especially on and around the top panel. This indicates that the device has been in use for some time and requires thorough cleaning. Mechanical components such as the power button, adjustment keys, and flow meter knob appear physically intact. The front cover is also in place, and no functional issue can be inferred from the visual inspection.

Technical Review and Details

Visual-based analyses of the device’s electronic and mechanical components are detailed below.

• Screen Analysis: The device’s digital screen is operational. On the screen, the value 08626 is displayed under the heading “COUNTS (hours)”. This indicates that the device has been used for a total of 8626 hours. In the “TIMING (minutes)” section, the “–” expression is present, indicating that no time setting has been made. Additionally, a green “I/O” light, indicating that the device is running, is active.
• Accessories: A transparent humidifier bottle with a black cap is visible inside the device in the images. Other accessories such as a power cable or nasal cannula for oxygen delivery are not present. An oxygen outlet port labeled “OXYGEN OUTLET” is located on the front left side of the device.
• Controls: The device’s front panel includes an on/off (POWER) button, “+” and “-” keys for time adjustment, operation/warning lights, and a flow meter adjustable between 1 and 5 L/min.

Potential Risk Assessment

No obvious malfunction or broken parts were detected on the device in the images; the device is operational. However, the high usage time of 8626 hours indicates that the performance of internal components such as filters or molecular sieve (sieve bed), which require periodic maintenance, may have decreased over time. This situation could affect the purity of the oxygen produced by the device. The overall condition of the device appears to be improvable with careful maintenance and cleaning. No significant physical damage risk has been observed.
