RespiroX SZ-T Oxygen Concentrator Analysis Report

Device Identification

The device in the examined images is a medical Oxygen Concentrator used for medical purposes. It is an electronic unit that takes in ambient air, separates it, and provides high-purity oxygen to the patient. Furthermore, upon examining the output ports on its front panel, it has been determined that this device possesses a nebulizer feature for medication applications, in addition to standard oxygen support.

Brand and Model

As a result of a detailed examination of the product in the images, its brand and model have been definitively identified. The brand and model information is clearly printed on the front face, at the bottom of the device.

• Brand: RespiroX
• Model: SZ-T

The phrase “OXYGEN CONCENTRATOR” is also present on the product, and its brand logo features a stylized graphic resembling a heartbeat.

Condition and Status Assessment

General Condition: The cosmetic condition of the device is visually very good. No yellowing, significant dirt, or signs of heavy use are observed on its outer casing. It retains its “white goods” shine. It gives the impression of being almost new or very lightly used.

Physical Deformation: No breaks, cracks, deep scratches, or dents have been detected on the plastic outer body (casing). The corners and joints appear solid. The housing for the humidifier reservoir looks clean.

Technical and Mechanical Analysis

Screen Analysis and Usage Time: The LCD screen on the device’s upper control panel is active and operational (blue backlight is on). The screen displays crucial data regarding the device’s history:

• Cumulative time (Total Usage): The phrase “00 129 hrs” is legible on the screen. This indicates that the device has only been used for 129 hours since its manufacture. Considering that oxygen concentrators have lifespans of thousands of hours, it can be said that this device is almost in “new” condition in terms of motor and compressor life.
• Single run time: It is “000 min” for the current operation.
• Indicators: The I/O light on the right side of the screen is green, indicating that the device is connected to power and the system is ready or operational, not in any fault mode.

Mechanical Components: The “Flowmeter” tube on the right side of the front panel is intact, and its internal ball mechanism is visible. The flow adjustment knob (regulator) immediately above it is in place. There is no visual damage to the front cover hinges or the water bottle holder mechanism.

Electronic Components: The device’s screen is operational. The Power Switch and the control buttons (+/-) next to the screen are complete and in place. The system status light is observed to be illuminated among the LED indicators on the panel.

Hardware and Features

The front face of the device includes the following functional inputs and outputs:

• Oxygen outlet: Oxygen output port (with metal tip).
• Nebulizing interface: Nebulization (vapor therapy) output port. This feature enables versatile use of the device.
• Flowmeter: Manual indicator showing oxygen flow in L/min (liters/minute).
• Water Tank (Humidifier): The original humidifier water tank, with a transparent reservoir and brown cap, is attached to the central part of the device. The hose connection point of the tank appears solid.

Areas of Use

This device is suitable for home oxygen therapy for patients suffering from COPD, asthma, or respiratory failure. It operates on electricity and provides continuous oxygen. Thanks to its nebulizer outlet, it is also used for administering liquid medications to the patient by vaporizing them.

Accessories and Quantity Information

The images show 1 unit of the main device. One humidifier bottle is attached to the device. A black power cable is visible on the floor towards the back of the device, but external accessories such as cannulas, masks, or spare filters are not present in the images.

Originality and Current Fault Status

Originality: The labeling, logo print quality, screen fonts, and material quality on the product are consistent with the original production standards of the RespiroX brand.

Current Faults and Risks: Visual analysis shows no signs that the device is faulty (broken parts, screen error codes, warning lights). There are no active warning indications next to the warning triangle or alarm (bell) symbols on the screen. The low usage time of 129 hours indicates that the device’s motor and valve system are not worn, which minimizes potential fault risks. Its condition is very good both technically and physically.
