The medical gases commonly used for anesthesia and critical care are oxygen, nitrous oxide, and medical air as the carrier for liquefied halothane. These gases are typically delivered from a central supply source, at a pressure of 50 to 55 PSIG (3.5 to 4 BAR), through a pipeline system to wall outlets for the anesthesia gas machine. Medical pressure regulators are used to reduce high-pressure cylinder sources to a lower pressure suitable for use with medical equipment or for the delivery of gas directly to a patient.
CONCOA medical regulators provide safe and convenient delivery of anesthesia gases supplied under high pressure, either in cylinders or via pipeline with cylinders on anesthesia machines for emergency backup. To accommodate full E-size cylinders, regulators for oxygen and medical air have a maximum inlet pressure of 3000 PSIG (210 BAR), while medical nitrous oxide regulators have a maximum inlet pressure of 2000 PSIG (135 BAR). A typical anesthesia machine requires a constant gas pressure of 45 to 85 PSIG (3 to 6 BAR) to ensure proper machine functionality and provide optimal gas delivery to the patient. CONCOA standard preset medical regulators have a set delivery pressure of 50 PSIG (4 BAR) that does not change with the cylinder pressure or the flow rate. Preset medical regulators are simple, reliable, and easy to use, as they do not require any adjustment by the user. They are suitable for anesthesia applications that do not need precise control of the flow rate. Adjustable medical regulators are used to regulate the flow from high pressure cylinders to a variable and precise level for patients or equipment. CONCOA adjustable medical regulators allow the user to adjust the delivery pressure from 0 to 100 PSIG (0 to 7 BAR). Once the delivery pressure is selected, it remains stable regardless of the filling level of the cylinder and how much gas flow is demanded. Adjustable medical regulators are suitable for anesthesia applications that need accurate control of the flow rate. They also help to optimize gas consumption and reduce the waste of gas.
CONCOA medical regulators are outfitted with Diameter-index Safety System (DISS) outlet connections specific to each medical gas. A variety of inlet connections based on cylinder size, pressure, and type of gas offer a level of safety by preventing improper connection of a gas source and device. Appropriate DISS non-interchangeable outlet connections ensure the connection with compatible medical hoses and attachments to avoid the delivery of incorrect gas. For countries following United States standards on medical regulators, CONCOA color-codes all medical devices according to their specific intended gas use, following United States Food and Drug Administration (US FDA) standardized medical color-coding guidelines. Color-coded medical regulators have matching colored gauges, knobs, and product labels, which help safeguard against erroneous misconnections of gas supplies or the administration of a hypoxic gas mixture.
CONCOA’s premier line of high-purity medical gas products include NFPA 99-compliant electronic switchover systems, medical manifolds, alarm systems, quality regulators, and medical gas pipeline systems specifically designed for use with anesthesia gases. Based upon the same engineering and manufacturing practices as CONCOA’s premier line of high-purity specialty gas regulators, CONCOA's medical regulators for anesthesia gases are meticulously cleanroom assembled and tested to the highest quality standards. For extended reliability and safety, CONCOA's medical regulators contain an encapsulated seat assembly for long life and ease of maintenance. Please note that CONCOA medical regulators are FDA-listed for therapeutic use. CONCOA regulators may not conform to local requirements for medical gas use outside of the United States, and no CONCOA regulator is CE-listed for medical applications in Europe.
