Medical Oxygen Cylinder and Regulator Analysis Report

Overview and Product Description

The images show a set of equipment used for supplying medical oxygen. This set consists of one small-sized oxygen cylinder, a pressure regulator (manometer) mounted on it, a flowmeter, and a humidifier bottle. Such systems are typically used for short-term or emergency oxygen support due to their portability. In the background, another device, which appears to be a larger oxygen concentrator on wheels, is visible, but the focus of the analysis is on the cylinder and its accessories in the foreground.

The quantity information for the products in the image is as follows:

• Oxygen Cylinder: 1 unit
• Pressure Regulator and Flowmeter: 1 unit
• Humidifier Bottle: 1 unit
• Oxygen Tubing: 1 unit

Brand and Authenticity Assessment

The brand of the products cannot be clearly identified from the images. The regulator’s pressure gauge has the inscription “EN 562 CE”; this is not a brand but a mark indicating the product’s compliance with European standards. Although the word “tuğmed” seems to be legible, albeit inverted and blurry, on the cardboard protector around the oxygen cylinder, this information is not definitive and is only a guess. Considering the overall workmanship of the devices and the compliance mark, there are no obvious signs of counterfeiting, but a definitive comment on authenticity cannot be made as the brand could not be confirmed.

Physical State and Condition

The products appear to be used. Their overall condition is moderate.

• Oxygen Cylinder and Regulator: No significant dents, cracks, or rust are observed on the metal parts. The blue-colored valve and adjustment knobs are in place. The glass of the pressure gauge is intact, and the pressure needle inside is above zero, indicating that there may be gas in the cylinder.
• Cardboard Protector: The cardboard sleeve wrapped around the cylinder is not a standard accessory but likely a worn piece added later for protection during transport.
• Tubing and Humidifier: The humidifier bottle appears to be intact. However, the green oxygen tubing coming from the humidifier shows slight dirt and discoloration.
• Background Device: Slight fading or yellowing is noticeable on the yellow casing of the oxygen concentrator seen in the background.

Technical Details and Accessories

The system consists of basic components connected to an oxygen cylinder. The regulator reduces the high-pressure oxygen in the cylinder to a safe pressure that can be delivered to the patient. The flowmeter on it is used to adjust and monitor the amount of oxygen delivered per minute (LPM). The humidifier bottle is used to reduce the drying effect of the oxygen delivered to the patient. No readable information regarding any label, serial number, lot number, or production date is found in the images.

Potential Risks and Recommendations

Based on the visual inspection, no obvious malfunction that would prevent the product from working has been detected. The fact that the pressure gauge shows a reading indicates that the system as a whole may be functional. However, as it is a used medical device, it is worth noting the following points:

• Hygiene: The dirty appearance of the oxygen tubing suggests it should be replaced for hygiene reasons. It is also important that the humidifier bottle be sterilized before use.
• Regulator Calibration: Medical gas regulators require periodic inspection and calibration to ensure they operate correctly and safely. Since the device’s history is unknown, it is recommended to have it checked by a specialist.

These notes are a preliminary assessment based solely on visual evidence and do not imply a definitive malfunction. The overall condition of the product suggests that it may be suitable for use after the necessary maintenance and cleaning have been performed.
