标准摘要
[中文适用范围]： 1.1 本文档规定了用于医疗气体供应系统中作为气体来源的设备的建造和运行要求，这些设备通过将氧气和氮气混合来产生空气。1.2 本文档适用于用于按特定比例混合氧气和氮气以生成合成医用空气和用于驱动手术器械的空气的比例单元。1.3 本文档适用于作为符合ISO 7396-1标准的医用空气供应系统的组成部分的比例单元，该系统用于供应医用气体管道分配系统。1.4 医用空气供应系统中比例单元的数量及其与其他供应源（例如气瓶集管）的组合，以确保供应系统至少包含三个供应源，超出了本文档的范围。医用空气供应系统的要求见ISO 7396-1。 [外文原描述]： 1.1 This document specifies requirements relating to the construction and operation of devices producing air through the blending of oxygen and nitrogen for use as sources of supply in supply systems for medical gases. 1.2 This document is applicable to proportioning units intended to produce synthetic medical air and air for driving surgical tools by mixing in defined proportions oxygen and nitrogen. 1.3 This document is applicable to proportioning units intended to be components of a medical gas supply system for medical air which supplies a medical gas pipeline distribution system complying with ISO 7396-1. 1.4 The number of proportioning units within the medical air supply system and their combination with other sources of supply (e.g. cylinder manifolds) to ensure that the supply system consists of at least three sources of supply is outside the scope of this document. Requirements for the supply systems for medical air are given in ISO 7396-1.
