Medical gas pipeline systems -- Dimensions and allocation of probes for terminal units for compressed medical gases and vacuum
This European Prestandard specifies the dimensions and allocation of probes intended to be connected to terminal units of medical gas pipeline systems specified in EN 737‑3 for use with the following medical gases:
oxygen;
nitrous oxide;
medical air;
carbon dioxide;
oxygen/nitrous oxide mixture (50/50 % V/V);
air for driving surgical tools;
nitrogen for driving surgical tools;
vacuum.
It is intended to ensure that only gas-specific probes are used so as to prevent wrong connection of probes to terminal units for different gases.
This European Prestandard specifies the dimensions of the probe intended to be connected to terminal units of medical gas pipeline systems specified in EN 737‑3 for supply and disposal of air for driving surgical tools.
This European Prestandard specifies the dimensions and allocation of each gas-specific connection point.
This European Prestandard does not specify the dimensions of NIST connectors. These dimensions are given in EN 739.
This European Prestandard does not specify the dimensions of probes intended to be connected to terminal units for anaesthetic gas scavenging systems. These dimensions are given in EN 737‑4.
This European Prestandard does not specify the suitability of material, cleanliness, testing, gas-specificity, identification and information. These are specified in EN 737‑1 which also applies to probes and gas-specific connection points.
