OXYTEK Oxygen Concentrator Detailed Product Analysis Report

Device Description and Brand Information

The device shown in the image is a medical device used to provide respiratory support, an oxygen concentrator. The brand logo and text on the product’s front panel have been clearly examined, and the device’s brand has been identified as OXYTEK. The panel also features the phrase “Oxygen Concentrator,” indicating the device’s function. No specific alphanumeric designation indicating the full model code of the device (e.g., OC-5 etc.) was found on the front, therefore only the brand identification has been definitively made.

Areas of Use and Functionality

This device takes ambient air, separates nitrogen with the help of internal filters, and provides high-purity oxygen to the user. It is typically designed for home or clinical use for patients with COPD, respiratory failure, or those requiring supplemental oxygen support.

Physical Characteristics and General Condition

The device’s outer casing is made of white hard plastic. Upon examining its general cosmetic condition:

• Casing Integrity: No visible cracks, breaks, or deep scratches were detected on the plastic casing. The device’s exterior appears clean and intact.
• Color Condition: No significant yellowing or discoloration is noticeable on the white plastic surface, suggesting that the device is not very old or has been well-preserved.
• Portability: An integrated carrying handle is located on the top, and black wheels are on the bottom. The front two wheels are clearly visible in the image, indicating that the device has a mobile (movable) structure.

Mechanical and Electronic Component Analysis

The controls and components located on the device’s front panel are as follows:

• Power Switch: In the upper left corner, there is a black “On/Off” (I/0) switch used to power the device on and off.
• Flowmeter: On the right side, vertically positioned, there is an analog gauge used to adjust and monitor the oxygen flow rate. The black ball inside indicates the flow setting. Although the scale cannot be fully read from the image, it is estimated to be in the standard 0-5 or 0-10 liters/minute range typical for such devices, but an exact value cannot be read due to the clarity in the image.
• Adjustment Knob: Directly above the flowmeter, there is a black rotary knob (regulator) used for manually adjusting the oxygen level.
• LCD Screen: An LCD information screen is present on the upper right side of the device. Due to the device’s operating status or the screen’s brightness at the time of the photograph, the text on the screen is unreadable.
• Warning Lights: Above the screen, there is an LED indicator panel displaying the device’s status (believed to have functions such as Power, Normal Oxygen, Low Oxygen, Service, etc.).

Accessories and Connections

The product in the image includes accessories suggesting it is ready for use:

• Humidifier Water Bottle: A transparent humidifier bottle is attached in the central slot of the device. The bottle has a black cap, and water is clearly visible inside. This indicates that the device is in active use or has been used recently.
• Oxygen Cannula: A transparent tubing nasal cannula, connected to the humidifier bottle’s outlet, is hanging on the device. There are no visible kinks or breaks in the tubing.
• Power Cable: On the left side of the image, a black power cable, understood to belong to the device, is on the floor.

Year of Manufacture and Label Information

Since the front view of the device is visible in the image, technical label information such as the year of manufacture, serial number (SN), reference number (REF), or lot number, which are usually located on the back or side panel, cannot be seen from this angle.

Current Fault and Risk Assessment

Based on visual inspections:

• Visible Faults: No broken parts, missing buttons, or physical damage are present on the device.
• Potential Risks: Due to the presence of water in the humidifier bottle, this water must be emptied before transporting the device; otherwise, there is a risk of water leaking into the electronic components. Furthermore, for hygiene purposes, it is recommended that filters, the humidifier bottle, and the cannula be replaced before use by a new user. Apart from these, no mechanical or electrical risks were detected from the image.
