Plusmed Portable Oxygen Concentrator Analysis Report

Device Identification

The examined visuals show a medical device set used for respiratory support. The main product is a portable oxygen concentrator with a compact, bag-type structure, battery-operated, and suitable for mobile use. The visuals include the device itself, a carrying bag, a charging station, a battery, a power adapter, and a nasal cannula (hose).

Brand and Model Information

The detailed examination of the visuals revealed the following identifying information:

• Brand: The Plusmed logo is clearly visible on the front face and control panel of the product.
• Model: The inscription pM-KN03T is faintly but legibly located just below the digital screen on the device’s control panel. (Note: This code is the technical model information written on the device’s casing).
• Power Adapter Brand/Model: The external power adapter is branded DELTA ELECTRONICS, INC. and its model number MDS-080AAS12 A is legible on the label.

Areas of Use

This device is manufactured to provide continuous oxygen support to patients suffering from COPD (Chronic Obstructive Pulmonary Disease) or other respiratory failure, when they are outside home, traveling, or mobile. This system, which separates oxygen from the air and delivers it to the patient, is used for medical treatment purposes.

Authenticity Status

Upon examination of the font of the logos on the device, label placement, and accessory quality (especially the use of a Delta Electronics brand adapter), the product is assessed to be an original Plusmed branded item. The phrase “Çin Malı” (Made in China) is visible on the adapter, which is standard for such electronic products.

Quantity Information

A total of 6 product items and accessories are visible in the visuals:

• 1 unit Oxygen Concentrator (Main Unit)
• 1 unit Black Carrying Bag (with strap)
• 1 unit Nasal Cannula (Oxygen hose)
• 1 unit Battery Charging Stand (Dock)
• 1 unit External Battery (inserted into the stand)
• 1 unit AC/DC Power Adapter (Adapter brick and cable appear integrated)

Overall Condition and Physical State

The device is second-hand and shows signs of use. Dirt, stains, and light scuff marks are observed in places on the white outer casing.

• Body: Slight darkening and wear are present on the upper corners and edges of the device due to use. However, no deep cracks or breaks have been detected on the casing.
• Control Panel: Slight discoloration or dirt is present on the gray coating of the button pad. Button symbols (Power On/Off, +, -, Volume) are not erased; they are clear.
• Power Socket: The 4-pin power input port on the side of the device (visual 5) appears clean, but there is a slight accumulation of dust around it. No bent pins are visible.

Electronics and Display Analysis

A single-line monochrome LCD information screen is located on the upper part of the device. Since the device is in the off position in the photos, the data on the screen (operating hours, oxygen level, etc.) cannot be read. LED indicator areas showing battery status and warnings are present on the control panel.

Mechanical Components and Accessories

• Carrying Bag: The original black carrying bag with a perforated (mesh/porous) structure to allow the device to breathe is present. The bag’s zippers and stitching generally appear sturdy, but there might be pilling and light dust on the fabric due to use.
• Oxygen Outlet: The metal oxygen output nozzle located on the upper front part of the device appears sturdy. The cannula hose is attached here.
• Battery and Charging Unit: A desktop charging unit (dock) independent of the device is visible. The white battery is inserted into this unit. An arrow indicating direction is embossed on the battery casing; no physical swelling has been observed.

Label and Technical Information (Adapter)

The technical data obtained from the label on the adapter are as follows:

• Manufacturer: DELTA ELECTRONICS, INC.
• Model: MDS-080AAS12 A
• Input: 100-240V ~ 2.0-1.0A 50-60Hz (Universal voltage compatible)
• Output: 12V ⎓ 6.67A (This value confirms the device’s high power requirement).
• Pin Structure: 4-pin round tip (Compatible with the device’s power input).

Existing Faults and Potential Risks

There is no concrete evidence in the visuals indicating that the device is not working or is faulty (e.g., broken screen, detached cable, error message). However, yellowing or hardening of the nasal cannula hose may pose a hygienic risk and might need replacement. The electronic health of the device can only be ascertained when powered on. Since no serious physical damage is observed, its condition, apart from cosmetic flaws, can be assessed as average-to-good.
