Oxygen Concentrator Analysis Report

Overview and Product Description

The product shown in the images is an oxygen concentrator used for medical purposes. The device is designed to take in ambient air, separate nitrogen, and provide concentrated oxygen. It is observed that the product has a wheeled structure that enhances its mobility, and it includes a humidifier reservoir and a connection hose. The report covers a total of one oxygen concentrator, one humidifier reservoir, and one short connection hose.

Area of Use and Function

This device is used to provide oxygen therapy for patients requiring respiratory support, either at home or in clinical settings. The flowmeter on it is used to adjust the amount of oxygen delivered per minute.

Physical Condition and Deformation

It is understood that the device is a used product in general. Its original white body color shows a yellowish discoloration that may have occurred over time or due to exposure to sunlight. Details regarding its physical condition are listed below:

• Casing: The device’s cream-colored casing has no significant cracks or breaks. However, scratches and friction-related wear have been observed on the dark grey plastic base at the bottom section, especially around the wheels.
• Humidifier Reservoir: White dust or lime scale residues are present inside the transparent humidifier reservoir. This suggests that the reservoir needs to be cleaned or replaced.
• General Cleanliness: Slight traces of dust and dirt are visible throughout the device.

Mechanical and Electronic Components

Visual inspection of the device’s mechanical and electronic components reveals no broken or missing parts. There is an integrated carrying handle on the top section. The front panel features a flowmeter, used to adjust the oxygen flow rate, displaying values between 0 and 5 L/min (liters/minute). On the device’s upper panel, there is a digital screen in an off state and several control buttons. Since the device is not in working condition, no comment can be made regarding the functionality of the screen or electronic components.

Accessories and Missing Parts

The accessories attached to the device in the image are a humidifier water bottle and a short transparent hose connecting the oxygen outlet to this bottle. Other accessories necessary for the device’s operation, such as a power cable or a nasal cannula (nose cannula) for patient use, are not present in the images.

Label and Warning Information

On the front of the device, there is an English warning label (CAUTION). This label contains important information regarding the device’s use and maintenance. The items on the label are as follows:

• The user manual must be read before use.
• Non-professionals are prohibited from opening the device’s casing.
• The air inlet filter should be cleaned every 100 hours, and the secondary filter every 300 hours.
• Oxygen purity is 93%±3 at the specified flow rate.
• Do not approach with cigarettes or open flames.
• Do not use oil or grease.

No other label with distinguishing information such as the device’s serial number, lot number, or REF code is visible in the images.

Potential Malfunction Risk

No obvious malfunction or broken parts have been observed on the device. The discoloration on the casing and scratches on the bottom section are aesthetic flaws of the product and are generally a result of normal use. The residues in the humidifier reservoir indicate the importance of regular maintenance. Based on visual evidence, no serious damage or high potential malfunction risk that would directly impede the device’s operation has been identified. The overall condition of the device appears reasonable for a used product.
