Medical Oxygen Cylinder and Regulator Set Analysis Report

Device Identification

The product shown in the visuals is a portable type oxygen cylinder used for medical purposes, with a pressure-reducing regulator (manometer) set mounted on it. The product is designed to store pressurized oxygen gas and regulate it for patient use.

Brand and Model

During the detailed examination of the product, the following brand and manufacturer information was identified:

• Cylinder Manufacturer Brand: The embossed markings on the metal neck of the cylinder show the inscription MES. This inscription indicates that the manufacturer of the aluminum cylinder is “MES Aluminum”.
• Label Brand/Supplier: The label affixed to the cylinder body bears the inscription BİLİR O2. This is the branding of the supplier company that fills or sells the product.
• Standard/Model Information: Codes 17E and AA6061 are present on the cylinder neck; these codes indicate the aluminum alloy type and production standard.

Areas of Use

This product is designed for individuals suffering from respiratory failure, COPD patients, or those requiring oxygen supplementation in emergency situations. Thanks to its 2-liter lightweight and portable structure:

• It is suitable for use in home care services,
• During patient transfer procedures,
• In ambulances and first aid kits,
• During inter-departmental patient transfers within hospitals.

Quantity Information

The visuals show 1 unit of aluminum oxygen cylinder and 1 unit of regulator with manometer integrated into this cylinder.

Dimensions and Volume Information

The technical data engraved on the metal body of the cylinder is clearly visible in the image:

• Water Volume: 2L (2 Liters). This indicates the internal volume of the cylinder.
• Empty Weight: 2.64KG. (Refers to the weight excluding gas and valve).
• Material Thickness: 4.6MM (Wall thickness).

Manufacturing Year and Test Dates

The manufacturing date information has been identified from the stamps on the cylinder neck:

• Manufacturing Date: 2018/01 (January 2018).

The periodic test period (hydrostatic test) for aluminum medical cylinders is generally 5 years. This cylinder might have needed to be tested in 2023. No additional stamp or label indicating a new test date (e.g., 2023 or later) is visible in the image.

Physical Deformation and General Condition

The external condition of the device is “good/used”. Notable details are as follows:

• Cylinder Body: The brushed aluminum body appears clean. No dents, deep scratches, or dings were detected.
• Paint and Surface: On the white paint of the cylinder neck, especially in the areas where the stamps are located, there are superficial paint chips due to friction. However, this condition is not of a magnitude to affect the cylinder’s functionality.
• Corrosion: As it is made of aluminum alloy (AA6061) material, there are no signs of rusting.

Mechanical and Hardware Components (Valve and Regulator)

The product has a regulator installed on a standard “pin index” or screw-type valve system:

• Regulator Body: The yellow brass/anodized body is clean.
• Inlets/Outlets: No breaks or bends are visible on the hose outlet tip (nipple).
• Valve/On-Off: The chrome butterfly valve with a blue cap on the valve top appears intact. The threaded parts are clean.
• Gauge (Manometer): The pressure gauge (manometer) glass on the regulator is intact, with no breaks or cracks.

Gauge Analysis and Fill Level

The manometer needle (as seen in detail in the 4th visual) is located at the far left of the red area, i.e., at the “0” point. This indicates that the cylinder is currently completely empty and contains no pressurized oxygen.

Technical Label and Warning Information

The breakdown of technical data found on the product’s engravings and labels is as follows:

• 17E TR 7 MES: Manufacturer and model coding.
• PW200: Working Pressure 200 Bar.
• PH300: Hydrostatic Test Pressure 300 Bar.
• EN1975: Manufacturing standard (Standard for seamless aluminum alloy gas cylinders).
• TT0036: Approved body or batch number.
• OXYGEN USE NO OIL: This inscription on the manometer is a critical safety warning indicating that it should absolutely not be touched with oily hands or oily substances (The combination of oil and pure oxygen creates a risk of combustion/explosion).

Potential Malfunction Risk and Evaluation

During the visual inspection, no breaks, cracks, or structural integrity deterioration were detected in the product. However, the following points should be noted:

• Since the manufacturing date of the cylinder is 2018, it should be confirmed by physical document control whether the 5-year periodic maintenance/test period has expired. There is no indication of the last test in the visuals.
• As the manometer shows “0”, the product is not currently ready for use; oxygen refilling is required.
• Since no oxidation or significant wear is observed in the socket and connection points, the regulator is evaluated to be mechanically sound.

Accessories

One metal regulator is available with the cylinder. Additional accessories such as an oxygen mask, nasal cannula (nasal tubing), or carrying bag are not present in the visuals.

Originality

The fact that the embossed stamps on the cylinder (MES, AA6061, Date, Pressure values) are of standard depth and font confirms that the product is an original industrial/medical product manufactured in accordance with standards. These detailed technical engravings are usually not found on low-quality counterfeit products.
