Plusmed Oxygen Concentrator Detailed Analysis Report

Device Identification, Brand and Model Information

As a result of a detailed visual inspection, the analyzed device has been identified as an Oxygen Concentrator used for medical purposes. Based on the logo and font characteristic located in the lower right corner of the device’s front surface, the brand has been determined with 100% certainty to be Plusmed.

The technical information label on the product’s front panel states “Oxygen Flow: 0-5 L/min”. Additionally, the flow meter indicator is graduated between 0 and 5. In light of this data, it has been confirmed that the device is a 5 Liter capacity model. Although a specific model number code (e.g., PM-L5 etc.) is not present on the front surface of the visual, the brand and capacity information can be clearly read from the visual.

Physical Condition and Cosmetic Examination

The device’s outer casing is generally robust, but signs of wear due to use and time are observed:

• Color Change: There are localized yellowing and color tone inconsistencies on the device’s white/cream plastic outer casing. This indicates that the device has been used for a certain period and exposed to sunlight or environmental conditions.
• Surface Stains: On the front panel, particularly around the warning text areas and in the lower sections, various small stains, black spots, and dirt accumulations are visible.
• Deformation: No deep cracks, fractures, or breakages have been detected on the casing. There are friction-induced marks and dust accumulation on the gray base strip at the bottom.

Mechanical Components and Accessories

The product in the visual consists of the main unit and its integrated components. The total parts and accessories status is as follows:

• Humidifier Bottle (Water Reservoir): One humidifier bottle is installed in the slot on the left side of the device. The transparent plastic part of the bottle has become slightly matte and cloudy due to use. The black rubber/strap mechanism securing the bottle is in place. The black cap and hose outlet nipples on the top of the bottle appear intact.
• Flow Meter: A vertical, ball-type mechanical flow meter is located on the left side of the front panel. The display glass is transparent, and the numbers from 0 to 5 on it are legible. Although the flow adjustment knob is not directly visible in this image, the flow tube is intact.
• Handle: An integrated handle for easy carrying is located on the top of the device. No damage is observed in the handle structure.

Label Information, Warnings, and Technical Data

On the front surface of the device, there are warning texts in both Turkish and English informing the user, as well as a technical data label at the top. The data readable from the visual are as follows:

Top Label (Technical Specifications):

• Oxygen Concentration: 93% ± 3% (Oxygen Concentration)
• Oxygen Flow: 0-5 L/min (Oxygen Flow)

Front Panel Warning Text (DIKKAT / CAUTION):

1. Please read the user manual before operating the machine.
2. Do not open the machine’s interior except for professional personnel.
3. It is recommended to clean the dust filter once a month and replace the air inlet filter once a month.
4. Oxygen concentration is 93% ± 3%.
5. DO NOT SMOKE OR HAVE OPEN FLAMES IN THE VICINITY.
6. DO NOT USE OIL OR GREASE.

These warnings contain critical information regarding the device’s maintenance and safe use (especially fire risk and filter maintenance).

Areas of Use and Purpose

This Plusmed branded device is a medical apparatus that takes ambient air, separates it, and provides high-purity (approximately 93%) oxygen to the patient. It is suitable for use in the following areas:

• For home treatment of chronic respiratory diseases such as COPD, Asthma.
• For patients undergoing long-term oxygen therapy.
• For home care of patients discharged from hospitals and requiring oxygen support.

The device operates with electricity and is for stationary use; it is not a portable (battery-powered) mobile model.

Potential Malfunction Risk and General Condition Assessment

The product is in used (second-hand) condition. Physically, it is intact, and its vital parts (water bottle, flowmeter tube) appear complete. However, the following points are noteworthy regarding potential risks:

• Hygiene and Filters: The dirt on the device’s exterior surface and the cloudy appearance of the humidifier bottle suggest that the device has not been cleaned for a long time. Although it cannot be determined from the visual whether the “monthly replacement of the air inlet filter” and “cleaning of the dust filter” procedures mentioned on the warning label have been carried out, maintenance is likely needed.
• Humidifier Bottle: The water reservoir is a consumable item. For hygiene purposes, it is recommended that any new user replace this bottle with a new one.

No malfunction lights or broken parts are visible in the image, and mechanical integrity has been maintained. Although the functionality of the electronic components cannot be tested through the visual, the casing integrity indicates that the device has not sustained a major impact.
