INOX Oxygen Concentrator and Direct Nexus Nebulizer Analysis Report

Device Identification

Two main medical product groups have been identified in the visuals. The first of these is a mobile electric oxygen concentrator, whose detailed visuals are shared and which is out of its box. The second is a compressor nebulizer device, which is boxed and stands next to the device in the first visual. An oxygen concentrator is a medical device that filters ambient air and provides concentrated oxygen to the patient.

Brand and Model

As a result of detailed examination in the visuals, the brand and model information of the devices are as follows:

• Oxygen Concentrator Brand: INOX
• Oxygen Concentrator Model: The phrase “INOX OXYGEN CONCENTRATOR” is prominently displayed on the front and top panels of the device in the visuals. Although the product’s technical type label is not clearly legible, the brand and product type are fixed on the visual.
• Nebulizer Brand (Boxed Product): Direct NEXUS
• Nebulizer Model: MD77S8805SND-01 (Confirmed from information on the box).

Areas of Use

INOX Oxygen Concentrator: Used for home oxygen therapy for patients suffering from COPD, lung diseases, and respiratory failure. It aims to increase blood oxygen saturation by providing a continuous flow.

Direct NEXUS Nebulizer: Used to deliver liquid medications in vapor form to the upper and lower respiratory tracts. According to the box information in the visual, it is suitable for use by both adults and children in conditions such as asthma and bronchitis.

Originality and Label Information

The labels and panel writings on the device (especially the Turkish warning labels) indicate that the product is a commercial medical product imported or manufactured for the Turkish market. Its original stickers are intact.

The instruction label on the top of the device contains the following information and warnings:

• “TECHNICAL SERVICE” heading and partially visible contact numbers.
• Maintenance instructions under the “ATTENTION IMPORTANT” warning.
• Information that filters should be washed every 10 days with intensive use, dried, and reinstalled.
• The water tank should never be removed while the device is operating.

On the boxed nebulizer, technical specifications such as “Lower Respiratory Tract”, “Particle Size <3μm", "Adult and Child Mask” are specified.

General Condition and State

Oxygen Concentrator: The device is second-hand and has a clean appearance. No yellowing that might occur over time on the plastic casing is observed; it retains its white and turquoise color tones. No major cracks, fractures, or dents that would hinder use have been detected on the outer casing.

Nebulizer: Only its box is present in the visual, and the box appears closed/new.

Physical Deformation and Cosmetic Condition

The general casing of the oxygen concentrator is intact. There are no openings at the corners or joints. Gelatin or protective sheen is present on the screen panel. The water tank slot and flowmeter section are robust. Wheels providing mobility are present underneath the device and are in place.

Mechanical and Electronic Components

• Display: It has an LCD digital display. Since the device is off in the visuals, the screen is not active, but the location of the digital digits in the “888888” format is clear.
• Flowmeter: A manually adjustable, “ball” type flow indicator is present. The indicator ranges from 0 to 5 liters/minute (LPM). The black adjustment knob is on it.
• Buttons: The front panel features an on/off (I/O) switch, timer, and mode buttons. The buttons appear complete.
• Water Reservoir: The humidifier water tank is attached to the device with its connection apparatus.

Accessories and Quantity Information

In addition to the main device, a rich set of spare parts and accessories can be seen in the visuals:

• 1 unit Main Device (INOX Oxygen Concentrator).
• 1 unit Boxed Nebulizer device.
• 1 unit Humidifier Water Tank attached to the device.
• 3 spare units of unopened Humidifier Water Tanks in transparent pouches (with their lid mechanisms).
• 1 unit gray spare humidifier cap.
• 2 spare units of cassette-type blue Hepa/Felt Filter boxes (in their pouches).
• 1 unit Oxygen Mask/Cannula set (on the device).
• The power cable is wrapped around the back of the device.
• The device is inside its original transport box/carton.

Year of Manufacture and Usage Period

A clear year of manufacture “Year: 20XX” cannot be read on the device’s labels. However, the “Direct NEXUS” box and the overall design of the device conform to current medical standards. Since the screen is off, the total operating hours cannot be read from the visual.

Battery Status

Devices of this type (home oxygen concentrators) typically do not have internal batteries; they operate directly with mains electricity (220V). A fixed electrical plug is visible at the back of the device in the visuals.

Existing Faults and Potential Risks

As a result of visual analysis, no signs of malfunction such as broken parts, disconnected cables, missing buttons, or screen damage are observed on the device. The connection points and filter inlets of the humidifier water tanks appear clean.

Points to be considered:

• There is a risk of the short hose (cannula) connecting the water tank to the device hardening over time, but it appears intact in the visual.
• Depending on use, regular replacement of filters (the blue boxes with spares available in the visual) is required.

Overall, the product appears to be a complete set with its spare parts, ready for use, and in a well-preserved condition.
