25、e method of connecting medical equipment intended to administer medical gases to patients or power medical devices. Medical gases are stored in cylinders or cryogenic vessels, or can be produced on site; several medical devices (e.g. pressure regulators, hose assemblies, flow-metering devices, lung
26、ventilators, anaesthetic workstations) can be fitted between the source of supply and the medical device. At each interface gas-specific connectors are needed to ensure that the intended medical gas is administered to the patient.While the desirability of achieving agreement on a single Internationa
27、l Standard for screw-threaded connectors has never been in doubt, the present pattern of usage has made such agreement impossible.Nevertheless, fears that proliferation of individual national standards or practices will eventually result in potentially dangerous cross-connection between components f
28、or different gases have led to the choice of several different connector systems, all of which are intended to be incompatible with each other.This International Standard specifies the dimensions and the allocation of non-interchangeable screw threaded (NIST) connectors for use with medical gases.Th
29、is International Standard does not specify the dimensions and the allocation of diameter index safety system (DISS) connectors specified in CGA V-59, sleeve indexed system (SIS) connectors specified in AS 28967, and quick connectors designed for terminal units specified in ISO 9170-15.
