Plusmed PURO Oxygen Concentrator Analysis Report

Device Identification and Brand/Model Analysis

The device, examined in detail in the visuals, is an oxygen concentrator used for medical purposes, which separates oxygen from ambient air and delivers it to the patient. A detailed examination of the product has definitively identified the following brand and model information:

• Brand: Plusmed (The text “plusMED” and the red-blue circle logo with a plus sign are clearly visible from the logo on the panel.)
• Model: PURO (The text “PURO” is prominently displayed in large letters on the front panel.)
• Manufacturer Information: The text “Manufactured by EMGTECH” is located below the control panel.

Areas of Use and Purpose

This device is designed for patients suffering from COPD (Chronic Obstructive Pulmonary Disease), asthma, or respiratory failure to receive long-term oxygen therapy at home or in a clinical setting. The device takes ambient air, filters out nitrogen, and provides high-concentration oxygen to the user.

Quantity Information

The visuals show a total of 1 unit of the Plusmed PURO oxygen concentrator main device. It includes 1 integrated humidifier water bottle and 1 electrical power cord wrapped at the back of the device.

Physical Characteristics and Capacity

The technical capacity and physical characteristics of the device have been analyzed based on visual data as follows:

• Oxygen Flow Capacity: The “Flowmeter” tube on the device’s front right side has a grading from 0 to 5. The phrase “LPM O2” (Litre Per Minute) is located at the bottom. This indicates that the device is a model capable of producing a maximum of 5 liters of oxygen per minute.
• Humidifier Reservoir: A transparent humidifier water bottle is placed in a recessed area on the device’s front body. This bottle is used to prevent the oxygen from being delivered dry to the patient and irritating the respiratory tract.
• Design: The device features a wheeled structure for easy portability and a sturdy integrated carrying handle on the top.

Control Panel and Electronic Components

The upper control panel features important indicators that provide information about the device’s status:

• ON/OFF Switch: A black, presumably illuminated, mechanical power switch is present.
• Warning Lights: LED indicator points are located next to “Service Required” and “Power” labels, indicating status.
• Counter (Hour Display): A digital counter on the LCD screen displays the device’s total operating hours.

Usage Time and Screen Analysis

One of the most critical analysis points is the device’s service life. The number “14505” is visible on the digital screen in the visual. Below it, the text “Hours” is located. This indicates that the device has been used for approximately 14,505 hours. For oxygen concentrators, this is a considerably high usage time, proving that the device has been actively in service for a long period.

Label and Warning Information

Various informational labels have been identified on the upper part and handle section of the device:

• Operating Instructions: On the handle, the following steps are listed in English: “Read the patient manual”, “Attach accessories”, “Turn on the power switch”, “Adjust the flowmeter”, “Change the air inlet filter as needed”.
• Service Label (Red): A red, Turkish service label, which appears to have been affixed later, is present on the device’s handle. The label displays “TRIMPEKS MERKEZ TEKNİK SERVİS” and the phone number “0212 319 50 00”. Additionally, warning texts regarding maintenance periods (filter replacement, etc.) and “If the oxygen concentrator is used continuously, rest it for 15 minutes every 3 hours” are included. This label confirms that the device is supported or sold by an authorized service network in Turkey.

Overall Condition and Cosmetic State

The overall appearance of the device is in “used” condition. The body plastic is intact, but there are certain signs of use:

• Casing: The gray plastic casing is entirely intact; no major cracks or fractures are visible. However, light scuff marks (abrasion/friction) and dust are present on the darker gray plastic parts (above the wheels) in the lower sections of the device due to rubbing.
• Panel: The control panel label is clean, and the text is legible. However, there might be very slight lifting at the edges of the label that can occur over time.
• Accessories: The humidifier bottle’s hose connection is attached. The condition of the black cap appears sturdy.

Accessories and Cables

Upon examining the rear of the device in visual 2, the black electrical power cable is seen neatly wrapped in its cable storage slot at the back of the device. An oxygen mask or nasal cannula (the hose leading to the patient) is not present in the visuals; only the device and its main components are visible.

Potential Malfunction Risk and Evaluation

The visual inspection does not reveal any mechanical breakage or apparent electronic damage on the device (it is not clear in the visual if the “Service Required” light is on). However, the most important point to consider is the following:

High Operating Hours Risk: The device being at 14,505 hours may indicate that internal components such as the compressor and zeolite sieve beds could be approaching the end of their lifespan. Oxygen concentrators typically require extensive heavy maintenance or part replacements at specific hour intervals (usually around 5,000 – 10,000 hours). The Turkish service label on the device also mentions maintenance periods. Therefore, the device should be evaluated under the category of “Operational but potentially in need of heavy maintenance.” It is important for the buyer to have the filters and oxygen purity checked.
