1. INTRODUCTION

1.1 Equinox® II DEMAND VALVE

Pressure Regulators

O-Two Medical Technologies Equinox® II Demand Valve provides trained individuals with a safe and effective means of providing analgesia (pain relief) by inhalation.

Simply wipe down regulator parts after use with a commercial disinfectant/antimicrobial agent. Do not immerse regulator in fluid or subject to autoclaving. If further sterilization is required due to infectious disease, a cold Ethylene Oxide gas sterilizing cycle may be used. Oil, grease or hydrocarbon-based sealants must be used on this equipment.

O-Two Medical Equinox® II Demand Valves are lightweight, portable, and extremely durable. Designed for the demands of the pre-hospital and in-hospital environment, they can be operated anywhere 50% Nitrous Oxide/50% Oxygen mixture cylinders are available. Note: Only those individuals trained in the administration of Nitrous Oxide/Oxygen mixtures should use this equipment. Thoroughly review the instruction manual before use.

1.2 WARRANTY

WARRANTY O-Two equipment is manufactured from the finest quality materials. Each individual part is subject to strict quality control tests to ensure exceptionally high standards. The manufacturer warrants to the purchaser of DEMAND VALVE (RESUSCITATOR) that its component parts are free from defects in material and workmanship for a period of two years from the date of purchase. The manufacturer will replace and /or repair all parts of the resuscitator at its option for two years from the date of purchase at no cost to the purchaser, upon the notification of the defects, in writing by the purchaser. All shipping costs shall be borne by the purchaser. The manufacturer shall be liable under this warranty only if the resuscitator and its parts have not been used and serviced in the normal manner described in the instruction manual. There are no other expressed or implied warranties. This warranty gives no specific legal rights. You may also have other rights which may vary according to local regulations.

4.3 TO REPLACE A DEPLETED CYLINDER

Ensure that the cylinder to be changed is turned Off (clockwise), and any remaining gas bled out of the regulator. 2. Loosen the T-bar on the regulator yoke by turning counter-clockwise. 3. Lift the regulator off the cylinder post valve. 4. Remove the used washer located in the yoke adapter and replace with a new one (usually supplied with each freshly filled cylinder). 5. Ensure that the new cylinder is labeled 50% Nitrous Oxide/50% Oxygen (Entonox). 6. “Crack” the new cylinder by quickly turning the cylinder on and then off. This ensures that the post valve is clean of any foreign material. 7. Place the regulator on the full cylinder’s post valve, ensuring that the guiding pin and inlet port on the regulator, line up with the corresponding holes on the cylinder post and that the cylinder washer is in place. NOTE: Small medical gas cylinders are protected from inadvertent interchange by a Pin Index Safety System. Guiding pins will only allow Entonox regulators to be used on Entonox cylinders. Should your regulator not fit a cylinder which supposedly contains Entonox, do not lubricate, force or remove the guiding pin to make it fit. Instead, return the cylinder to the supplier immediately. 8. Tighten the T-bar until very snug. 9. Slowly turn the cylinder ON (counter-clockwise at least one full turn). If a leak around the cylinder post is noted, first further tighten the yoke T-bar. If this does not correct the leak, washer replacement may be required. DO NOT PLACE ANY REGULATOR INTO SERVICE WITH A SIGNIFICANT LEAK, AS THIS MAY SEVERELY DETRACT FROM ITS FUNCTION. RETURN THE UNIT IMMEDIATELY TO THE MANUFACTURER OR AN AUTHORIZED O-TWO MEDICAL DEALER. 10. Confirm that the regulator gauge reads FULL. 11. Check for proper function of all components. 12. Ensure that the cylinder is turned OFF after each use, bleed off the residual gas in the system using the Equinox® II Demand Valve Bleed Pin and return equipment to storage neatly.

The O-Two Medical Equinox® II Demand Valve is intended for use by suitably trained and qualified personnel.

4.2 MAINTENANCE Pressure regulators and their auxiliary components should be checked at least every six months, and more frequently in high use applications. OTwo Medical equipment is not designed for field disassembly and service. Even pressure gauges on some regulator models are specifically matched to each individual regulator’s functional characteristics, and thus cannot simply be replaced. NOTE: Outlet fittings and components must be moved from one regulator port to another. The full 2000 psi pressure of the gas cylinder may be transmitted directly to inappropriate equipment with disastrous consequences. Any units requiring modifications, or determined as malfunctioning, should be returned to the manufacturer or an authorized O-Two Medical Dealer. Unauthorized repairs will nullify the product warranty. 4 9

3.2

CLEANING THE Equinox® II DEMAND VALVE

Routine cleaning of the O-Two Medical Equinox® II Demand Valve should be undertaken to maintain the equipment in a clean condition. Sterilize face mask, patient valve and diaphragm which are used for equipment coming into contact with partients using most common disinfecting solutions such as CIDEX or 10% bleach solution. Rinse thoroughly with water after sterilization. All other components should be cleaned with a mild soap solution. WARNING: Do not attempt to clean and sterilize any components that are designated as disposable as immersion of these items into a sterilizing solution can cause degeneration of the materials. CLEANING PROCEDURE The Equinox® II Demand Valve must be thoroughly cleaned after each patient use. 1. 2.

3. 4. 5. 6. 7.

Ensure that the cylinder is turned off (completely clockwise) and any remaining gas bled out of the regulator. Remove the facemask from the Equinox® II Demand Valve, and then disconnect the demand valve from the regulator. This is accomplished by counter-clockwise turning of the connection nut at the regulator end of the hose. A wrench may be required. Unscrew patient valve from the unit body being careful to ensure that the diaphragm is retained. Wash all components thoroughly in a mild soap solution and disinfect as required. The handpiece can be wiped over with a soft cloth and mild soap solution. Dry all components thoroughly. Re-assemble and check performance.

2. OPERATING PROCEDURE 2.1 DEMAND BREATHING The O-Two Medical Equinox® II Demand Valve is a device powered by the 50 psi output gas from the pressure regulator. Its function is to provide gas to the patient at a safe delivery pressure and adequate flow rate upon demand. An inspiratory effort by the patient will open the demand valve and oxygen/nitrous oxide will flow to the patient at a rate and volume in line with their inspiratory effort.

2.2 OPERATING INSTRUCTIONS 1. Ensure that the Equinox® II Demand Valve/Regulator connection is snug. 2. Turn the cylinder handwheel counter clockwise to the ON position (at least one full turn). 3. Ensure that the regulator contents gauge reads greater than 500 psi. If not, replace with a full cylinder. 4. Attach the Universal facemask to the Equinox® II Demand Valve outlet. 5. Instruct the patient in its operation. Most protocols insist that the gas be self-administered by the patient to prevent inadvertent excessive administration by an attendant. 6. To trigger the demand valve and obtain an adequate flow of gas, it is necessary to make a good mask to face seal. Simply place the mask on the patient’s face, covering both the nose and mouth. Instruct the patient to hold the mask on his/her face with a light pressure and breath normally. The sound of gas flowing should be heard with each inspiration. If not, adjust the patient’s hold on the mask for a better seal and ask the patient to breath more deeply. 7. Continue administration as per local management protocol.
