与医疗气体系统一起使用的高压柔性连接

[中文适用范围]： 本国际标准适用于旨在连接到标称充装压力最高为 25 000 kPa（15 °C 时）的气瓶或气瓶组的高压柔性连接件，用于以下医用气体：氧气；氧化亚氮；呼吸用空气；氦气；二氧化碳；氙气；上述气体的混合物；用于驱动手术工具的空气；用于驱动手术工具的氮气；富氧空气。本国际标准适用于旨在将气瓶或气瓶组连接到符合 ISO 7396-1 的医用气体管道系统源中的歧管的高压柔性连接件。本国际标准适用于旨在将气瓶连接到装有符合 ISO 10524-1 的集成压力调节器的医疗设备（例如麻醉工作站或肺呼吸机）的入口端口的高压柔性连接件。本国际标准不适用于旨在用于填充气瓶的高压柔性连接件，也不适用于由 ISO 5359 涵盖的低压柔性软管组件。 [外文原描述]： ISO 21969:2009 applies to high-pressure flexible connections intended to be connected to cylinders or cylinder bundles with nominal filling pressures up to 25 000 kPa at 15 °C for use with the following medical gases: oxygen; nitrous oxide; air for breathing; helium; carbon dioxide; xenon; mixtures of the gases listed above; air for driving surgical tools; nitrogen for driving surgical tools; oxygen-enriched air. ISO 21969:2009 applies to high-pressure flexible connections intended to connect cylinders or cylinder bundles to manifolds within sources of supply of medical gas pipeline systems complying with ISO 7396-1. ISO 21969:2009 applies to high-pressure flexible connections intended to connect a cylinder to an inlet port of medical equipment (e.g. anaesthetic workstation or lung ventilator) fitted with an integral pressure regulator complying with ISO 10524-1.
