Respirox SZ-5AW Oxygen Concentrator Analysis Report

Device Identification

The analyzed visuals belong to a medical respiratory support device. Based on the components on the device’s front panel and the markings on it, this product has been identified as an Oxygen Concentrator that produces oxygen from ambient air and delivers it to the patient. The device features an integrated humidifier reservoir, a flowmeter, and an electronic control panel.

Brand and Model

Based on the clear visual data on the front of the device, both on the lower part of the body and on the label, the brand and model of the product are as follows:

• Brand: Respirox
• Model: SZ-5AW
• Device Type: Oxygen Concentrator

The model name “SZ-5AW” is clearly written in capital letters on the device’s front panel, directly below the logo.

Originality

Upon examining the brand logos, model designation, typographic print quality, and information labels on the device’s casing, it is assessed that the product is an original item, manufactured to industrial standards and possessing brand-specific characteristics. The casing joints and panel placement are consistent with original factory production.

Areas of Use

This device is designed for patients experiencing respiratory insufficiency or requiring supplementary oxygen support. It operates electrically, drawing ambient air, separating nitrogen, and producing oxygen with over 90% purity. Furthermore, thanks to the “Nebulizing interface” output located on the front panel, the device can also be used for medication vaporization (nebulizer) applications.

Quantity Information

The visuals show a total of 1 unit of the main device (Respirox SZ-5AW Oxygen Concentrator). Additionally, various consumables and accessories are visible in the device’s upper storage compartment.

General Condition and Usage Duration

The data on the device’s LCD screen provides the clearest information regarding its usage status:

• Total Usage Hours (Cumulative time): 08947 hrs.
• Single Run Time: 000 min.

The cumulative usage period of 8947 hours indicates that the device is a heavily used (second-hand) product. This duration proves that the device has been operated for an extended period during an active patient treatment process. However, visually, the device appears well-maintained and clean.

Physical Deformations and Cosmetic Condition

The device’s white plastic casing generally appears clean. On the lower front panel where the “Respirox” logo is located, some hairline surface scratches or minor scuff marks are visible due to light reflection, but no deep cracks, breaks, or severe impact marks have been observed. No significant yellowing of the plastic components has been detected.

Mechanical and Hardware Components

The mechanical examination based on the visuals is as follows:

• Flowmeter: The mechanical flow tube and adjustment knob located on the right side of the device appear intact. The scale ranges from 0-5 L/min.
• Wheels/Feet: Although the base of the device is not fully visible, its standing position is stable.
• Humidifier Slot: A humidifier water container is installed in the transparent-covered/recessed area in the middle of the front panel.
• Lids and Hinges: The lid of the accessory storage compartment on the top of the device is open, and the hinge mechanism appears sound.

Electronic Components and Screen Analysis

The device appears to be connected to electricity, and its screen is active:

• Screen: The blue-backlit LCD screen is operational. There are no missing pixels or readability issues. A green light is illuminated next to the “I/O” indicator on the screen, indicating that the device is receiving power or is turned on.
• Control Panel: To the right of the screen, there are “+” and “-” adjustment buttons and the main power switch. No excessive wear or fading has been observed on the buttons.
• Connection Ports: The “Oxygen outlet” (metal output tip) and “Nebulizing interface” (nebulizer output) ports are sound and clean; no signs of oxidation or rust are visible.

Accessories and Contents

Aside from the device itself, the following accessories are visible in the storage compartment under the top lid:

• Oxygen Cannula: 1 unit of a tube-form cannula or extension tube, removed from its transparent pouch.
• Filter: 1 unit of a black, spongy spare filter (likely an air intake filter) inside a sealed bag.
• User Manual/Document: A piece of paper or booklet with text is present on the compartment floor (text is not readable).
• Power Cable: A black electrical cable is visible emerging from the bottom of the device.
• Humidifier Bottle: Attached to the front body of the device.

Battery Status

This type of home-use/stationary oxygen concentrator typically operates solely on mains electricity. The visuals do not indicate an external battery pack or internal battery usage. The device is designed for wired operation.

Current Faults and Potential Risks

No error codes or warning symbols (Alarm triangle or Service icon) are active on the device’s screen; the system appears to be in normal operating (standby or running) mode. However, considering the high usage life of 8947 hours, it is technically highly probable that the zeolite tanks (molecular sieves) or the compressor inside the device are due for maintenance. Visually, there is no risk of obvious broken or detached parts requiring immediate intervention.
