Analysis Report of Oxygen Cylinder Set with Pulse+Med Regulator and Kasweld Valve

Device Identification

The product examined in the visuals is a medical oxygen set used for medical purposes. The set is a complete unit consisting of a high-pressure steel oxygen cylinder, a regulator (pressure gauge) that reduces and adjusts pressure, a flowmeter, and a humidification jar.

Brand and Model Information

As the product is a combination rather than a single piece, brand information has been identified on a component basis:

• Regulator/Pressure Gauge Brand: The Pulse+Med logo is clearly visible on the pressure gauge dial of the product.
• Valve Brand: The Kasweld brand is embossed on the brass valve located on the neck of the cylinder.
• Cylinder Manufacturer: Standard industrial stamps are present on the cylinder body, but instead of a specific consumer brand (logo label, etc.), ISO standard codes are available.

Technical Specifications and Label Information

Prominent technical codes and safety warnings have been identified on the product, especially on the shoulder of the cylinder and on the regulator:

• Capacity: The inscription “5L” is embossed on the cylinder, indicating a water capacity of 5 liters.
• Weight: The inscription “8.01 KG” is readable on the cylinder shoulder (likely the weight of the empty cylinder).
• Standard Code: The “ISO9809” stamp is visible on the cylinder. This indicates the international quality standard for seamless steel gas cylinders.
• Warning Labels: The warning “USE NO OIL UNDER” is located at the regulator connection point. Additionally, pressure values of “14700 kpa / 150 Kg/cm2” are present.
• Humidifier Jar Inscriptions: The bottle features “UPPER LEVEL”, “LOWER LEVEL”, and “DISTILLED WATER PREFERRED” inscriptions, along with the “CE” mark.
• Pressure Gauge Information: The display panel includes the “CE 1639” certification number and colored pressure zones (red, green).

Areas of Use

This product is designed for patients suffering from respiratory failure or requiring supplemental oxygen support. It is used in hospitals, ambulances, infirmaries, and especially in home care services for the treatment of respiratory diseases such as COPD and asthma, or to provide oxygen to patients in emergency situations. Its manually adjustable design allows it to be used by healthcare professionals or trained patient relatives.

Authenticity Status

The logos of the brands (Pulse+Med and Kasweld), typefaces, ISO standard stamps, and the quality of brass casting indicate that the product is an original industrial/medical product manufactured in compliance with standards. There is no indication of a counterfeit or replica product.

General Condition and Physical State

The general cosmetic condition of the device is very good. It appears to be in “new” or “very lightly used” condition.

• Cylinder Body: The blue paint is generally vibrant and shiny. In the first visual, small white spots or scuff marks are visible on the paint on the right-middle part of the cylinder body, but this is not deep corrosion or damage.
• Metal Parts: The chrome plating of the regulator is shiny, and the brass valve part is clean. There are no signs of rust or oxidation.
• Humidification Jar: The plastic water reservoir is transparent and clear, with no calcification or yellowing, which suggests the product has been used very little or not at all.

Quantity Information

The visual shows 1 unit of a 5-liter oxygen cylinder and 1 mounted regulator/humidifier set.

Mechanical and Accessory Analysis

• Valve and Flow Adjustment Knob: The blue main on-off valve (on top of the Kasweld valve) and the flow adjustment knob (O2 Flow adjustment) on the regulator appear sturdy. No deformation is observed in the threads or connection points.
• Pressure Gauge Screen: The glass is clean, without breaks or cracks. The needle is at the zero position.
• Flowmeter Tube: The transparent scale tube is sound, with no cracks. The ball inside is visible.

Electronic Components

This device operates entirely on mechanical principles (pressure physics). It does not contain any digital display, battery compartment, cables, or electronic components.

Battery Status

The device has a manual mechanical structure; it does not require or contain an internal or external battery power source.

Current Faults and Potential Risks

No broken, cracked, or missing parts that would prevent the device from operating have been identified in the visuals. The product appears ready for use. However, as the product is a high-pressure oxygen cylinder, the following points are important:

• As explicitly stated on the product (USE NO OIL), oil, grease, or petroleum-derived substances must absolutely not come into contact with the connection points; this poses a risk of combustion/explosion under high pressure.
• The manufacturing date and hydrostatic test dates on the cylinder are not entirely clearly legible from the angle in the visual, but the ISO standard is present. Periodic testing of cylinders is required.

Documents

No invoice, warranty certificate, or user manual was found in the visuals. The product was shown in bare condition.
