Plusmed pM-KN01 Oxygen Concentrator Analysis Report

Overview and Device Identification

The product shown in the images is an oxygen concentrator used for providing respiratory support. The brand of the device is Plusmed, and based on an examination of the control panel and general design features, the model is estimated to be pM-KN01. This report has been prepared based solely on the evidence presented in the images and does not include a test of the device’s operational status.

Intended Use and Quantity

This device separates nitrogen from ambient air to produce high-concentration oxygen and is used in home or clinical settings to provide supplemental oxygen to patients with respiratory difficulties. The images show one Plusmed oxygen concentrator and one water humidifier bottle attached to the device. Other accessories required for the device’s use, such as a nasal cannula, are not present in the images.

General Status and Physical Condition

The overall condition of the device is assessed as used. Significant yellowing has occurred on its plastic casing over time. This suggests that the device has been used for an extended period or has been exposed to sunlight. Scratches, scuff marks, and minor stains from use are observed on various parts of the casing, particularly on the side and top sections. The protective film on the device’s digital screen is seen peeling at the edges with air bubbles underneath. These details indicate a history of heavy use.

Mechanical and Electronic Components

The device’s casters are in place and appear to be capable of providing mobility. The flowmeter, located on the front panel and used to adjust the oxygen flow rate, is physically intact. The power button and other control buttons are located on the top of the device; there are no obvious cracks or damage to these buttons. The attached water bottle and its connecting tube appear to be intact. The device’s power cord is not present in the images.

Label Information and Screen Analysis

There is a warning label on the side of the device prepared in Turkish and English. The information on this label is as follows:

• Dikkat (Turkish): It states that the user manual should be read, the device should not be opened by non-professionals, filters require periodic cleaning and replacement, the oxygen concentration is 93%±3, it should be kept away from cigarettes and flames, and oil should not be used.
• Caution (English): The same warnings are provided in English.

There is no label in the images containing specific manufacturing information such as the device’s serial number, lot number, REF code, or year of manufacture. The device’s screen is off. Below the screen, there are icons for alarms and status indicators such as “P.F.”, “L.P.”, “H.P.”, “O2”, “H/L.P”, and “H.O.”. The presence of these icons indicates that the device has alarm systems for conditions such as low/high pressure, low oxygen purity, and power failure.

Potential Fault Risk

The heavy yellowing and general wear on the device’s outer casing indicate long-term use. In oxygen concentrators, the components that separate oxygen from the air, known as molecular sieves (sieve beds), have a limited operational lifespan. Depending on the age and intensity of use of the device, the efficiency of these components may decrease over time. This situation carries the potential to cause a decrease in the purity of the produced oxygen. However, this is merely a prediction based on the visual condition and does not mean there is an existing fault. No obvious cracks, fractures, or rust indicating an imminent risk of failure have been observed on the device’s mechanical components or external structure.
