RespiroX SZ-T Oxygen Concentrator Analysis Report

Device Identification and Product Description

The analyzed images show a vertical-design oxygen concentrator that provides medical respiratory support. The device is an electrical medical equipment that takes ambient air, separates it, and provides high-purity oxygen to the patient. English phrases and functional buttons on the front panel indicate that the device has features for both oxygen support (“Oxygen outlet”) and nebulization (“Nebulizing interface”) for medication administration.

Brand and Model Information

Upon examining the logos and model codes on the product, brand and model information has been clearly identified:

• Brand: RespiroX (The logo is clearly visible on the front chassis.)
• Model: SZ-T (The model code is clearly written right below the logo.)

Technical Specifications and Hardware Analysis

The following data regarding the device’s technical hardware has been collected from the images:

• Oxygen Outlet and Nebulizer: On the left side of the device, there is a standard oxygen outlet port (“Oxygen outlet”) and immediately below it, a nebulizer interface (“Nebulizing interface”) with a metal cover.
• Flowmeter: The analog flowmeter located on the right side has a scale between 0 and 10 L/min (liters per minute). This is visual data indicating that the device can potentially offer flow measurement up to 10 liters per minute.
• Humidifier Reservoir: In the front-center part of the device, protected by a transparent cover, a humidifier water bottle is located. The connecting hoses of the bottle are attached.
• Control Panel: On the upper part of the device, there is a digital LCD screen, a Power On/Off (POWER) switch, and “+” and “-” buttons used for menu navigation or changing settings. Additionally, a green LED light for “I/O” status is actively lit on the panel.

Usage Time and Display Data

The device’s LCD screen provides the most critical data about the product’s usage history. The data on the blue-backlit screen, visible in detail in the second image, is as follows:

• Cumulative time: 00171 hrs. The device has been operated for a total of only 171 hours since its manufacturing date. This is a very low hour count for an oxygen concentrator and proves that the device falls into the “lightly used” category.
• Single run time: 000 min. No operating time has elapsed in the current session yet.
• Timer set: — min. No shutdown timer has been set.

Physical Condition and Cosmetic Examination

Observations made regarding the device’s external casing and physical condition are as follows:

• General Condition: The product appears very clean. No significant yellowing, discoloration, or dirt has been detected on the white plastic casing. It has an unworn appearance, supporting the low usage hours.
• Physical Deformation: No cracks, breaks, deep scratches, or dents have been observed on the front panel, around the screen, or on the transparent cover of the water bottle compartment. The cover hinges appear sturdy.
• Mechanical Components: The flowmeter adjustment knob, power switch, and panel buttons are physically intact and in place. No bending or breakage is visible on the oxygen and nebulizer outlet ports.

Labels and Markings

In addition to the brand, the following labels and inscriptions are present on the front face of the product:

• Service/Dealer Label: On the device’s body, above the model name, a label containing the phrase “Çallı Medikal” and carrying authorized service/dealer information has been affixed. The text on the label is legible and has remained clean without wear.
• Warning Signs: Standard warning icons (exclamation mark in a triangle, bell symbol) are located next to the LEDs on the panel.

Missing Parts and Accessory Check

• Humidifier Bottle: It is on the device; hose connections are made.
• User Manual/Documents: In the upper part of the device (in the 2nd image), some documents are visible inside a transparent file. Although their contents cannot be fully read, they are presumed to be the user manual or technical documents kept with the device.
• Patient Accessories: Consumables that come into contact with the patient, such as cannulas, masks, or extension tubes, are not visible in the images. These parts may need to be supplied separately.

Existing Fault and Risk Assessment

Based on visual analysis, the following conclusions have been reached regarding the device’s condition:

• Operating Status: The device’s “I/O” LED light is green, and the LCD screen is working flawlessly, displaying data. This indicates that the device is receiving power and the electronic panel is active.
• Risk Assessment: There is no visible sign on the casing that would indicate a risk of malfunction, such as cracks, liquid contact traces, or oxidation. The low operating life of 171 hours suggests that the motor and compressor components (though not visible) have likely not experienced mechanical fatigue and are in high condition.
