RespiroX SZ-5AW Oxygen Concentrator Analysis Report

Device Identification

The product in the examined visuals is a medical device, an oxygen concentrator, which separates oxygen from ambient air and provides high-purity oxygen to the user. The device is in a single piece and includes components such as a humidifier water bottle, a control panel, and a flow meter.

Brand and Model

As a result of detailed analysis of the texts on the visuals, the brand and model of the device have been definitively identified:

• Brand: The RespiroX brand, along with its distinctive heart rhythm logotype, is clearly visible at the bottom of the device’s front face.
• Model: On the front panel, directly below the brand logo, the model information is clearly stated as SZ-5AW.
• Device Type: The phrase OXYGEN CONCENTRATOR is displayed in capital letters on the front panel.

Originality

The print quality of the logos on the device, the placement of labels, the casting workmanship of the material, and the industrial design features give the impression that the product is an original RespiroX production. The “stickers” indicating features on the product appear to conform to manufacturer standards.

Areas of Use

The RespiroX SZ-5AW oxygen concentrator is used for individuals suffering from respiratory failure, COPD, or similar lung diseases to receive oxygen therapy at home or in clinics. The “Nebulizing interface” outlet shown in the visuals indicates that the device can also be used for medicated vapor (nebulization) therapy. This feature offers a combined use, allowing patients to both receive oxygen and inhale liquid medications in vaporized form.

Quantity Information

The visuals show 1 unit of the main oxygen concentrator device and 1 unit of a humidifier water bottle attached to the device.

General Condition

The device is in a used condition. The product, observed to be in second-hand condition, has signs of use on its exterior surfaces that have developed over time. The overall structure of the device maintains its integrity; it does not present a fragmented or disassembled appearance.

Physical Deformations

No deep cracks or large fractures were detected in the product’s white plastic casing in the visuals. However:

• Accumulated dust and dirt are present within the recessed compartment where the water bottle is located, and on the general exterior surface of the device.
• Superficial stains and dullness from use are visible on the plastic surface.
• No significant rusting has been observed on the metal components (nebulization outlet), but its surface is dull.

Mechanical Components

The condition of the device’s externally visible mechanical parts is as follows:

• Flow Meter: The transparent tube on the left side appears intact. The adjustment ball inside is at the lowest level (as the device is off). The adjustment knob on it is in place.
• Humidifier Reservoir Slot: The reservoir is seated correctly; no mechanical misalignment is visible.
• Covers and Mounting Screws: The screws on the upper part appear unrusted and in place.

Electronic Components and Screen Analysis

A digital LCD screen panel is located on the upper part of the device. In the visual, the screen is dark because the device is off, thus no comment can be made regarding pixel errors or screen functionality. Next to the screen are (+/-) buttons, presumed to be used for “Timer” settings, and an I/0 (On/Off) switch. The switch appears intact.

Accessories

The accessories identified in the visual are:

• Humidifier Water Bottle: It is attached to the central compartment of the device. It has a transparent plastic body and a brown cap. A green connector is attached to the upper hose connection point. It is not entirely clear from the outside whether there is scaling or sediment inside the bottle.
• Power Cable: The end or the entirety of the device’s power cable is not clearly visible in the visuals; although there are indistinct cables in the background, it is not certain if they are connected to the device.
• Missing Items: The nasal cannula (nosepiece) or mask for patient use is not present in the visual. The nebulizer set hose is not in the visual.

Battery Status

This type of home oxygen concentrator (such as SZ-5AW) typically operates on mains electricity (220V) and does not have internal batteries. The visuals also do not show an external battery pack or any indication of portability.

Label Information and Technical Details

The following features are highlighted on the information labels on the front face of the device:

• Superior Quality: Gold-colored quality emphasis.
• Continuous Operation: Blue clock icon.
• 93% ±3 Purity Oxygen Production: States that the device provides high-purity oxygen according to medical standards.
• Instant O2 Level Measurement: Indicates that the device monitors the purity level through its sensors.
• Eco-Friendly: Environmental sensitivity icon.
• Left Side Scale: Numbers from 1 to 5 are visible on the L/min O2 scale, confirming that the device can provide oxygen flow up to 5 liters per minute.

The warning label on the rear/side panel of the device (in Turkish and English) states the following:

• The manual must be read before use.
• Warning not to approach with fire (Oxygen accelerates combustion).
• Oil or petroleum products should not come into contact with the device.
• Risk of electric shock.
• Information that the yellow light on the front panel will illuminate if the oxygen level drops below 82% (This is an important technical detail).

Size and Compatibility

The product is of standard home concentrator dimensions (vertical form similar to a wheeled suitcase type structure). It is designed for adult use, but with appropriate flow settings and pediatric accessories, it may be suitable for use by different age groups under doctor’s supervision.

Existing Faults and Potential Risks

No broken parts, disconnected cables, or “Error” messages are visible in the visuals (as the screen is off). However, the device requires mechanical cleaning. Dust accumulation may indicate clogged filters, which could lead to the device overheating or operating noisily. Furthermore, the “Nebulizing interface” outlet lacks a cap, and dust entering it could pose a hygienic risk.

Evaluation Result

The examined RespiroX SZ-5AW oxygen concentrator is a used medical device that physically maintains its integrity, has missing accessories (mask/cannula) but includes its main component (humidifier bottle). Its external cosmetic condition is “usable,” but it is observed to require detailed cleaning and filter maintenance. From its labels, it is understood to have technical specifications suitable for standard treatment protocols, with a promised 93% purity and 5-liter capacity.
