RespiroX SZ-5AW Oxygen Concentrator Analysis Report

Device Identification

The product shown in the visuals is a medical device used for medical purposes. Upon examination, it has been determined that this device is an oxygen concentrator that takes ambient air, separates nitrogen through its molecular sieve system, and provides high-concentration oxygen to the user. The device also features a nebulizer outlet used for vaporizing liquid medications.

Brand and Model

The brand and model information is clearly legible on the front face of the product and in the user manual placed on the device.

Brand: RespiroX

Model: SZ-5AW

An online check has confirmed that the RespiroX brand operates in the field of medical respiratory devices and that the SZ-5AW model is actively available in the market.

Originality

Upon examining the logo prints on the product, the “Oxygen Concentrator” font, the flowmeter design, and the corporate information (Support line numbers, importer company websites, etc.) in the accompanying Turkish user manual/warranty certificate, the product is assessed as original. No signs of aftermarket or counterfeit imitation are observed.

Areas of Use

This device is designed for home use for patients with COPD, respiratory failure, or low blood oxygen saturation. It supports the patient’s respiration by providing high-concentration oxygen. Furthermore, thanks to the “Nebulizing interface” outlet visible on the front panel, it also allows for its use in patients’ medicated vapor therapy (as a nebulizer).

Quantity Information

The visuals show a total of 1 main device and its accompanying accessory sets. The set includes; 1 humidifier bottle attached to the device, spare filters in their packaging, and 1 oxygen cannula, along with documents placed on the device.

Overall Condition and Physical Deformity

Upon examining the external cosmetic condition of the device, its condition appears to be very high. No yellowing, cracks, deep scratches, or impact marks were found on the white plastic casing. The device’s front panel, buttons, and water tank reservoir appear clean. The impression is that the device is “like new” or has been used very little. The condition of the wheels and the cleanliness of the bottom parts of the casing indicate that the device has not been used under harsh conditions.

Mechanical Components

The mechanical parts appear visually sound:

• Flowmeter: The adjustment knob on the right side is in place, and the indicator tube is transparent and unbroken.
• Water Bottle Slot: The transparent lid and hinge system appear sturdy.
• Wheels: Black wheels are present and in place.
• Inputs/Outputs: The metal tips of the oxygen outlet port and nebulizing interface port are intact, with no deformation observed.

Electronic Components and Screen Analysis

The device’s top panel features an LCD screen, control buttons, and an on/off (I/O) switch. Since the device is not shown plugged in or operating, the screen is dark; therefore, no comments can be made regarding dead pixels or screen backlight. However, the physical integrity of the panel is complete, with no fading or wear on the buttons. The power switch appears sturdy.

Battery Status

This type of device (home oxygen concentrators) typically operates with mains electricity (220V) and does not have internal batteries. No external battery unit is visible in the visuals either. The device operates directly with a power cable.

Accessories and Consumables

The condition of the accessories provided with the device is as follows:

• Humidifier Bottle (Water Reservoir): It is attached to the device’s slot, appearing clean and transparent.
• Oxygen Cannula: Under the device’s top cover, in a transparent zip-lock bag, there is one unopened nasal oxygen cannula with a green tip.
• Filters: Within the same bag, compatible black sponge-type spare filters (presumed to be air inlet filters) are present.

Label Information and Technical Details

The technical data and label information obtained from the visuals are as follows:

• Capacity: Numbers from 0 to 5 are present on the flowmeter on the front face, indicating that the device provides oxygen flow up to 5 liters per minute (5L/min).
• Document Date: The date “September 2019” is legible on the user manual. This suggests that the device’s documentation or production period dates to late 2019 and beyond.
• Contact Information: The warranty certificate states “SUPPORT LINE 444 78 96”, and website addresses “www.respirox.com.tr” and “www.ecemedikal.net”.

Dimensions and Compatibility

The device is of standard home oxygen concentrator dimensions. Compared to a radiator, it can be estimated to be approximately knee-high or slightly above. It is suitable for adult use; for pediatric use, the flow rate adjustment should be made under medical supervision.

Documents and Warranty Status

In the visuals, a “RespiroX Oxygen Concentrator SZ-5AW User Manual” and a warranty certificate form are seen on top of the device. The lower part of the document contains clauses related to technical service and warranty terms. However, since it is not legible from the visual whether the document has been filled out or what the sales date is, definitive information regarding whether the warranty is still valid cannot be provided.

Existing Faults and Potential Risks

There are no findings in the visuals indicating that the device is faulty (broken part, error warning, burn marks, rust, etc.). The product is in excellent cosmetic condition.

Potential Risk Note: If the device has been stored for a long time, there is a theoretical possibility that the molecular sieves (sieve bed) inside could be affected by moisture, but this can only be determined by measurement at a technical service center. During the visual inspection, no rust, crushed cables, or filter clogging risks that would concern the user were observed.
