A system of differential delivery pressures and hose diameters for use in hospital medical gas installations.
Medical gases can be identified simply if they are supplied at different pipeline pressures. Routine maintenance errors, accidental pipeline cross-connections, or gas failures, can be automatically detected by incorporating a pneumatic unit with pressure-sensitive valves into the anaesthetic machine. A fail-safe method of ensuring the delivery of the correct gases to the patient is described.
