5. d personnel working in controlled conditions must perform disassembly assembly and testing of regulators and flowmeters gt Only BPR Medical approved spare parts should be used to maintain the regulator gt Do not submerge the device in any fluid Ensure that no fluid is allowed to enter the inlet valve or the vent holes gt The threaded bull nose cylinder connection for medical oxygen and medical air may be the same Ensure that you have the correct cylinder for the application UK only gt The holes in the side of the body of the device are for venting gas in the event that the over pressure valve is activated Do not obstruct these holes or interfere with the over pressure valve in any way gt These regulators are designed for use for cylinder pressures up to 20 000 kPa 3 000 psi 200 bar do not attempt to connect BPR Medical regulators to cylinders having fill pressures in excess of this value 2 2 Cautions gt The performance of the device may be affected if it is stored or transported in temperature outside of the range 20 C to 60 C 3 Functional Description The BPR Medical range of regulators provide a safe and convenient way of connecting high pressure gas cylinders to flowmeters ventilators and other equipment required to run from a low pressure gas source A regulator is connected to the gas cylinder via one of a number of different designs of inlet connector that are the result of differing gas bottl
6. e connection standards across the world The lower outlet pressure of the regulator is achieved by balancing the force applied by the gas on a piston head with a spring of known characteristics A valve seat limits the flow of gas restricting the force that can be applied on the piston head until such time as a state of equilibrium can be reached in the system i e the outlet pressure The specific characteristics of the valve seat piston and spring combine to determine the outlet pressure As gas is drawn from the regulator the outlet pressure drops and the valve opens in an attempt to maintain the equilibrium under the new gas flow conditions An over pressure valve OPV protects the user from any high gas pressures by venting excess pressure to ambient The OPV is a spring loaded valve with a pre set operating pressure Particulate filtering in the form of a 40 micron inlet filter is incorporated to prevent the ingress of debris which may alter the performance of the device and increase the risk of a fire Outlet pressure is available at the outlet connector to enable the end user to fit the intended delivery device e g flowmeter 4 Operating Instructions Check that the cylinder type and regulator inlet connector are compatible Check the presence and condition of the input connector seal Note For pin index regulators this is a washer type seal yoke seal and an O ring for bull nose regulators Check that a suitable device
7. e g flowmeter is correctly connected to the output of the regulator Fit the regulator to the cylinder ensuring that it is properly mated and the connectors are done up hand tight Open the cylinder valve with a suitable cylinder key Check the regulator cylinder contents gauge to verify that there is sufficient gas available Continue to check the regulator contents gauge Upon completion of the therapy close the cylinder valve and disconnect any outlet hoses that might be connected to the patient To remove the regulator from the cylinder first ensure the cylinder valve is closed Bleed off any residual gas pressure in the regulator by turning on the connected ancillary device Remove the regulator from the cylinder and store it carefully where it will be protected from contamination 5 Maintenance 5 1 User Maintenance and Inspection All regulators should be inspected and tested on an annual basis to ensure correct performance Wipe down the outside of the device with an alcohol wipe Do not allow the ingress of water or other solution into the device Check the exterior condition of the device Notes e Pay particular attention to the input connector seal and cylinder contents gauge e Check that the holes in the side of the body of the device for venting gas in the event of relief valve activation are not obstructed or have otherwise been tampered with 5 2 Service Repair Regulators must be serviced on or before the Service
