本文件在ASTM持有TC 121的美国标签时获得批准并发布，但现在已成为AAMI标准。原始格式已被保留，因此与典型的AAMI样式有一些不同。ISO 5366的本部分给出了塑料和/或橡胶制成的儿科气管造口管的要求 内径从2.0毫米到6.0毫米。儿科气管造口管接头和接头的要求 还给出了适配器。

This document was approved and published when the U.S. TAG for TC 121 was held by ASTM, but it is now an AAMI standard. The original formatting has been maintained, so there are some variations from the typical AAMI style.This part of ISO 5366 gives requirements for paediatric tracheostomy tubes made of plastics materials and/or rubber having inside diameters from 2.0 mm to 6.0 mm. Requirements for paediatric tracheostomy tube connectors and adaptors are also given.
