An Oxygen Regulator Pin Index (Double Gauge) is a medical device used to control and monitor the flow of oxygen from a gas cylinder to a patient or medical equipment.
What it does
- Reduces the high pressure from the oxygen cylinder to a safe working pressure
- Controls oxygen delivery
- Displays pressure readings using two gauges
Meaning of “Pin Index”
The Pin Index Safety System (PISS) is a safety mechanism that ensures the regulator can only connect to the correct gas cylinder.
For oxygen cylinders, specific pin positions prevent accidental connection to the wrong gas type.
Meaning of “Double Gauge”
A double-gauge regulator has two pressure gauges:
- Cylinder Pressure Gauge
- Shows how much oxygen remains in the cylinder
- Delivery/Flow Pressure Gauge
- Shows the output pressure being delivered
Common uses
These regulators are commonly used in:
- Hospitals
- Ambulances
- Emergency oxygen kits
- Clinics
- Home oxygen therapy
Typical components
- Pin index connector
- Pressure adjustment knob
- Two gauges
- Oxygen outlet for tubing or flowmeter attachment
