Description: An oxygen (O₂) regulator with pin-index refers to a specific type of device used to regulate the flow of oxygen from a cylinder or tank to a medical application. Here’s a breakdown of its key components and how it functions:

1. Regulator: The main body of the device that controls the pressure and flow of oxygen from the cylinder.
2. Pin-Index System: This is a safety feature that ensures the correct type of regulator is attached to the oxygen cylinder. It consists of two metal pins on the regulator that fit into corresponding holes on the cylinder valve. This ensures that regulators are not interchanged with those intended for other gases, preventing dangerous mix-ups.
3. Flow Control: Allows the user to adjust the rate at which oxygen flows from the cylinder. This is typically measured in liters per minute (LPM).
4. Pressure Gauge: Indicates the pressure of the oxygen inside the cylinder, providing a visual indication of how much oxygen is left.
5. Safety Features: Oxygen regulators include safety features such as pressure relief valves to prevent over-pressurization of the system.
 

Assembly and Safety

When assembling or using an oxygen regulator with pin-index:

• Ensure Compatibility: Verify that the pins on the regulator match the pin holes on the oxygen cylinder valve.
• Secure Attachment: Properly secure the regulator to the cylinder to prevent leaks.
• Inspect Regularly: Check the regulator and cylinder for damage or wear regularly to ensure safe operation.
• Follow Manufacturer Instructions: Always follow the specific instructions provided by the manufacturer for setup, use, and maintenance of the regulator.
