A medical oxygen gas cylinder regulator and flow meter is a device attached to an oxygen cylinder to control and measure the flow of oxygen delivered to a patient. It’s a crucial component in oxygen therapy, especially in hospitals, clinics, emergency services, and home care settings.
🔹 What It Is:
-
The regulator controls the pressure of oxygen released from the high-pressure cylinder.
-
The flow meter adjusts and shows the rate of oxygen flow (typically in liters per minute, or L/min).
-
Together, they ensure safe, controlled, and accurate delivery of medical-grade oxygen.
🔹 Key Features:
-
Pressure Regulator:
-
Reduces high pressure (up to 2000–3000 psi from the cylinder) to a safe working pressure.
-
Prevents sudden release of gas, which can be dangerous.
-
Includes a pressure gauge to indicate how much oxygen is left in the cylinder.
-
-
Flow Meter:
-
Allows adjustment of oxygen flow from 0 to a specific rate (commonly 0–15 L/min or 0–25 L/min).
-
Types:
-
Rotameter (ball-type): A clear tube with a floating ball to indicate flow.
-
Dial-type: Rotary knob with preset flow markings (less common in medical settings).
-
-
-
Humidifier Bottle Connector (optional):
-
Can be attached to add moisture to the oxygen to prevent dryness in the nose and throat.
-
Especially useful for long-term oxygen therapy.
-
-
Inlet and Outlet Ports:
-
Inlet connects to the cylinder valve.
-
Outlet connects to tubing, nasal cannula, face mask, or other delivery devices.
-
-
Material:
-
Typically made from brass, stainless steel, or chrome-plated alloy for durability and safety.
-
-
Safety Features:
-
Pressure relief valve to prevent over-pressurization.
-
Color-coded knobs or dials (green for oxygen in most countries).
-
Flame-retardant materials (due to oxygen’s high flammability risk).
-
-
Portability:
-
Compact and lightweight regulators are available for home or mobile use.
-
Compatible with both small (portable) and large oxygen cylinders.
-
✅ Benefits:
-
Ensures precise oxygen delivery according to patient needs.
-
Helps monitor cylinder pressure and oxygen supply levels.
-
Improves safety in oxygen therapy by regulating pressure and flow accurately.
