RespiroX SZ-5AW Oxygen Concentrator Analysis Report

Device Description, Brand and Model Identification

The device in the examined images is an oxygen concentrator used for medical purposes. Based on the “RespiroX” logo on the product’s front panel and the “SZ-5AW” designation immediately below it, the device’s brand has been identified with 100% certainty as RespiroX, and its model as SZ-5AW. Additionally, the inscription “OXYGEN CONCENTRATOR” on the panel confirms the device’s function.

General Condition and Cosmetic Examination

Visually, the device is in “used” condition and exhibits noticeable signs of wear. Color changes or light-induced reflections are observed on the white outer casing, which have occurred over time, but the overall integrity is preserved. Noteworthy cosmetic details include:

• Screen Surface: The protective film or screen glass over the control screen on the top panel appears worn, blistered, and deformed in places. Distinct scratches are present in this area.
• Casing Cleanliness: Accumulations of dust and dirt layers are visible at the “Oxygen outlet” and the junction of the front panel. It is clear that the device requires detailed cleaning maintenance.
• Adhesive Residue: Transparent tape residue or adhesive marks are present on the front cover and side parts, suggesting that the device may have undergone previous transport or securing.
• Door Mechanism: A transparent water tank cover is present on the front of the device and opens from its hinges, fulfilling its function. Usage-related dullness may be observed on the plastic material of the cover.

Technical Components and Interface Features

During the technical examination conducted via the images, the following components were identified on the device’s front face and control panel:

• Flowmeter: On the right side, there is a vertical tube scaled from 0 to 5 L/min (Liters per Minute). The flow adjustment knob (regulator) is positioned immediately above the tube.
• Output Ports: On the left side, there are two metal outlets. The upper one is labeled “Oxygen outlet,” and the lower one is labeled “Nebulizing interface.”
• Control Panel: At the very top, there is a digital LCD screen. To the right of the screen are “+” and “-” adjustment buttons, and to the left are buttons thought to be related to menu or timing (with an I/O symbol). Additionally, a mechanical “POWER” switch is present.

Electronic and Mechanical Operating Status

The images show that the device is electrically connected and has been activated:

• Screen Status: When the device is plugged in and the power button is switched on, the LCD screen’s blue backlight illuminates. The active screen indicates that the device’s electronic board is receiving power.
• LED Indicators: The green LED light next to the power switch is illuminated, indicating that the power supply is functioning without issues.
• Flow Indicator: While the device is operating, the black ball inside the flowmeter is observed to rise. This condition proves that the compressor is generating air and there is airflow in the system.

Accessories and Battery Status

No integrated or external battery system could be visually identified on the device; the product operates with standard mains electricity (wired). Accessories identified in the images include:

• Power Cable: A black electrical cable extends from the bottom left of the device and is plugged into an outlet.
• Humidifier Water Tank: Behind the transparent cover, there is a clear water container (humidifier bottle) with a black lid. A quantity of liquid (likely water) is present inside the container.
• Connection Hoses: Connection hoses run from the lid of the water tank towards the device’s internal mechanism. Additionally, a transparent cannula or hose extension is partially visible at the device’s outlet.

Potential Malfunction Risk and Deficiencies

Although the device appears to be in working condition (screen light on, airflow present), its physical condition is categorized as “heavily used.” Particularly, the dirt in the air inlet-outlet ports and between the panels suggests that the filters or internal components may also be similarly dusty. The nebulizer outlet cap is in place, but there are signs of oxidation or contamination on the surrounding metal parts. The readability of the screen is difficult due to the film deformation on its surface, despite the brightness of the backlight.

In summary; this product, confirmed to be the RespiroX SZ-5AW model, is a second-hand medical device that is in working condition, has all its essential components (water tank, buttons, cover) present, but requires detailed cleaning and hygienic maintenance.
