Oxygen Regulator Set

WhatsApp Order

An Oxygen Regulator Set is a critical pressure control device that attaches to a medical oxygen cylinder, reducing its extremely high internal pressure to a safe, usable level and providing precise control over the flow rate delivered to the patient. Consisting of a pin-indexed yoke, high-pressure gauge, adjustable flowmeter, and safety outlet, it is the essential interface for safe oxygen delivery from cylinders in emergencies, during transport, and in home care. Its safe operation hinges on absolute adherence to oil-free handling procedures, correct connection techniques, and regular inspection for leaks or damage to prevent catastrophic oxygen-fuelled fires or equipment failure.

Oxygen Regulator Set

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Pressure Reduction & Flow Control for Oxygen Cylinders

Primary Use: Attaches to a high-pressure medical oxygen cylinder to reduce the cylinder’s high internal pressure to a safe, usable working pressure and provides precise control over the flow rate delivered to the patient.
How it helps: For the respiratory therapist, nurse, or home care provider, the regulator transforms a dangerously pressurized cylinder into a controlled, therapeutic tool—taking thousands of pounds of pressure and delivering it as a gentle, metered flow. For the patient receiving oxygen, the regulator ensures they receive exactly the flow their doctor prescribed—no more, no less—protecting them from both undertreatment and the dangers of excessive, unregulated oxygen delivery.

2. Emergency & Backup Oxygen Administration

Primary Use: A critical component of emergency oxygen kits, crash carts, ambulance systems, and hospital backup systems where piped wall oxygen is unavailable or fails.
How it helps: For the code team and emergency responders, a regulator-equipped cylinder means oxygen is immediately available anywhere—in the parking lot, the radiology suite, or during a power outage when wall oxygen fails. For the patient in respiratory distress, whether in a hospital corridor or at a disaster scene, the regulator on the portable cylinder ensures they receive controlled, therapeutic oxygen even when the usual systems are unavailable.

3. Patient Transport

Primary Use: Used whenever a patient on supplemental oxygen is moved within a facility or during ambulance transport, regulating flow from the portable cylinder.
How it helps: For the transport team moving a patient to CT, MRI, or between facilities, the regulator provides continuous, controlled oxygen delivery throughout the journey. For the oxygen-dependent patient being moved, the regulator ensures their oxygen flow remains consistent during elevator rides, hallway transfers, and ambulance transport—no interruption in the support they depend on.

4. Home Oxygen Therapy (Cylinder Systems)

Primary Use: For patients who use oxygen cylinders as their primary or backup oxygen source at home, the regulator is the interface that allows them to safely control their prescribed flow.
How it helps: For the home care provider and respiratory therapist training patients, the regulator gives patients independent control over their oxygen therapy—a simple, understandable interface for a life-sustaining treatment. For the patient managing COPD, pulmonary fibrosis, or other chronic lung conditions at home, turning the dial on their regulator to the prescribed setting means they can breathe comfortably, move freely, and maintain their quality of life.

SECONDARY & SUPPORTIVE USES

1. Oxygen-Powered Nebulizer Drive: For the respiratory therapist, certain regulator sets include a nebulizer outlet that provides continuous, unregulated high-pressure oxygen specifically to power a jet nebulizer for aerosolized medication delivery. For the patient requiring both oxygen and nebulized medications, this integrated function means they can receive bronchodilators and other inhaled drugs while maintaining their oxygen therapy, all from a single source.

2. Calibration & Testing: For the clinical engineer and biomedical technician, regulators are essential tools for testing and calibrating other oxygen delivery devices throughout the hospital. For every patient who receives oxygen therapy in that facility, these calibration activities ensure that every regulator, every flowmeter, and every delivery device performs exactly as intended, maintaining the safety and accuracy of oxygen delivery across the entire institution.

KEY PRODUCT FEATURES

1. BASIC IDENTIFICATION ATTRIBUTES

Device Type: Pressure-Reducing and Flow-Control Valve Assembly.
Core Components: A complete set typically includes:
1. Pressure Regulator Body: Houses the pressure reduction mechanism.
2. Cylinder Valve Connection (Yoke or Pin-Index): A BSL (Bodok Seal) yoke with pin-index system for medical gas cylinders to ensure connection only to an oxygen outlet (preventing gas mix-ups).
3. High-Pressure Gauge: Shows the pressure (in psi or bar) inside the oxygen cylinder, indicating how much gas remains.
4. Flowmeter/Flow Control Valve: A thorpe tube with a floating ball or bobbin and a calibrated scale (in LPM). The user adjusts a knob to set the desired flow rate.
5. Outlet Port: A DISSi (Diameter Index Safety System) outlet or threaded outlet to connect oxygen tubing or a mask.
Cylinder Compatibility: Must match the cylinder type (e.g., yoke for small cylinders like D/E, threaded for large H-size tanks).

2. TECHNICAL & PERFORMANCE PROPERTIES

Inlet Pressure Rating: Must withstand the full cylinder pressure (typically up to 2000-2200 psi).
Outlet/Working Pressure: Reduces pressure to a safe, low level (often around 50 psi for the flowmeter circuit).
Flow Range: Typically adjustable from 0 to 15 LPM or 0 to 25 LPM, covering all clinical needs from low-flow nasal cannula to high-flow non-rebreather masks.
Accuracy: The flowmeter must provide an accurate reading, typically within ±10% of the set flow rate.
Safety Features:
- Pin-Index Safety System (PISS): Prevents attachment to the wrong type of gas cylinder (e.g., nitrous oxide, air).
- Pressure Relief Device: A built-in safety valve that vents gas if the regulator's internal pressure becomes dangerously high.
- Crackling/Burst Disc: A one-time safety device on the cylinder valve itself that ruptures to prevent cylinder explosion in a fire.

3. PHYSICAL & OPERATIONAL PROPERTIES

Construction: Made of brass, chrome-plated brass, or stainless steel for durability and safety with high-pressure gases.
Gauges: Protected by a sturdy housing. The flowmeter tube is often made of durable plastic.

4. SAFETY & COMPLIANCE ATTRIBUTES

Regulatory Standards: Must be manufactured and tested to stringent standards for pressure vessels and medical devices. Key standards include ISO 10524 (Pressure regulators for medical gases) and general pressure equipment directives.
Gas-Specific: Permanently labeled and configured for OXYGEN USE ONLY. Using a regulator for any other gas can cause catastrophic failure (e.g., oil contamination from an air regulator causing an oxygen fire).

5. STORAGE & HANDLING ATTRIBUTES

Storage: Store in a clean, dry environment. Protect from dust, dirt, and physical impact. Keep the outlet port and yoke clean and capped when not in use.
Handling – OIL-FREE PRECAUTION (CRITICAL): Oxygen under pressure supports violent combustion. The number one rule is: NEVER allow any oil, grease, or hydrocarbon-based lubricant to contact any part of an oxygen regulator, cylinder valve, or connection. Handle only with clean, dry hands or gloves.
Cylinder Connection Procedure:
1. "Crack" the cylinder valve for an instant to blow out any dust.
2. Inspect the regulator yoke and Bodok seal for damage.
3. Connect the yoke to the cylinder valve, ensuring pins align.
4. Hand-tighten the T-screw securely.
5. Slowly open the cylinder valve fully to pressurize the regulator, watching the high-pressure gauge.
6. Set the desired flow rate.

6. LABORATORY & CLINICAL APPLICATIONS

Primary Application: The indispensable interface that makes a high-pressure oxygen cylinder a safe and functional source for patient therapy in any setting outside of piped gas systems.

SAFETY HANDLING PRECAUTIONS

1. SAFETY PRECAUTIONS

Oxygen Compatibility (Most Critical): Use only oxygen-compatible materials. No oil, grease, dirt, or adhesives. Never use a regulator that has been used for any other gas.
Cylinder Security: Ensure the oxygen cylinder is securely chained or placed in a stand to prevent it from falling over, which could shear off the valve.
Leak Check: After connecting, listen and feel for leaks at the connections. A common method is to use a leak detection solution (soapy water) – never use oil-based solutions.
Opening the Valve: Always open the cylinder valve slowly to avoid a sudden pressure surge that could damage the regulator or cause adiabatic heating (which can ignite contaminants).
No Modifications: Never attempt to repair or modify a regulator. Service must be performed by qualified personnel.

2. FIRST AID MEASURES

Regulator/Cylinder Fire: If a fire occurs at the regulator or cylinder valve (indicated by a roaring sound, heat, or flame), if it is safe to do so, immediately close the cylinder valve to cut off the fuel source. Evacuate the area and call the fire department. Do not attempt to move a burning cylinder.
Cylinder Fall/Valve Shear: If a cylinder falls and the valve is sheared off, the cylinder can become a deadly projectile. Evacuate the area immediately.

3. FIRE FIGHTING MEASURES

Extreme Hazard: A fire involving high-pressure oxygen will be intense and rapid. The primary goal is to shut off the oxygen supply by closing the cylinder valve if safe.
Firefighter Instructions: Alert firefighters to the presence of high-pressure oxygen cylinders. They will use appropriate tactics for a pressurized gas fire and may apply water from a safe distance to cool adjacent cylinders and prevent BLEVE (Boiling Liquid Expanding Vapor Explosion).
