Oxy-Life Oxygen Concentrator Analysis Report

Device Description and Area of Use

The device shown in the visuals is an oxygen concentrator. Such devices separate nitrogen from ambient air to produce enriched oxygen and are used to provide a continuous flow of oxygen to patients requiring respiratory support. The flowmeter on the device allows for adjusting oxygen flow between 0 and 5 liters per minute.

Brand and Model Identification

On the front of the device, in the circular logo at the bottom, the phrases “OXYGEN CONCENTRATOR” and “OXY-LIFE” are present. Based on this information, the device’s brand is understood to be Oxy-Life. No other text or label indicating model information could be identified in the visuals.

General Condition and Assessment

The general condition of the device is assessed as used. There is noticeable yellowing in the body color and widespread scratches and scuff marks throughout. This indicates that the device has been used extensively and for a long period. The wheeled structure of the device suggests it is a portable model.

• Quantity Information: 1 oxygen concentrator is present in the visuals.
• Accessories: No accessories belonging to the device (power cord, oxygen cannula, humidifier cup, etc.) are present in the visuals.

Physical Examination

Upon detailed examination of the device’s outer casing, various deformations resulting from heavy use have been observed. Specifically, numerous scratches, stains, and discoloration are present on the light-colored body. Deep scratches and peeling are also noticeable on the device’s dark-colored bottom base and side surfaces. No broken or cracked parts have been identified.

Mechanical and Electronic Components

The mechanical and electronic components of the device have been visually examined:

• Wheels: There are four wheels underneath the device. The wheels appear functional, but dirt and wear are present on them.
• Control Panel: A digital screen and three control buttons are located on the top of the device. Since the screen is off, it is not possible to determine if it is working or displaying any error codes. No physical damage is observed on the buttons.
• Flowmeter: The flowmeter glass, which indicates oxygen flow, is intact and legible. The adjustment knob is in place.
• Oxygen Outlet: The oxygen outlet port is in place, and no significant damage is observed.

Label and Warning Information

On the front of the device, there is a warning label (CAUTION) containing important information. The instructions on this label are as follows:

• Read the owner’s manual before use.
• Non-professionals are prohibited from opening the machine casing.
• Clean the air inlet filter every 100 hours of operation.
• Clean the secondary filter every 300 hours of operation.
• Oxygen purity is 93%±3% at the specified flow rate.
• Smoking or approaching with open flames is prohibited.
• Do not use oil or grease.

No other label containing a serial number, lot number, or REF code could be identified on the device.

Potential Risk Assessment

The heavy wear, yellowing, and numerous scratches on the device’s outer casing constitute a negative aesthetic condition. This degree of external wear suggests that the device has been used extensively and for a long period. Although no broken parts or signs of malfunction are visible, it is recommended that the device undergo a detailed technical inspection to ensure flawless operation. It is especially important to check critical information such as the condition of its filters and its operating hours.
