GB/T 45811-2025Anaesthetic vaporizers - Agent-specific filling systems (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is modified to adopt ISO 5360:2016 "Specialized filling systems for anesthetic vaporizers".

The technical differences between this document and ISO 5360:2016 and their reasons are as follows.

--- ISO 1101 was replaced by the normative reference GB/T 1182 to adapt to my country's technical conditions (see Figure 1).

The following editorial changes were made to this document.

--- Added examples of Chinese color system (see Table 2);

--- Change the term dedicated anesthetic filling system to injection (see 3.2).

1 Scope

This document specifies the requirements, including dimensions, for filling systems for anesthetic agent-specific vaporizers used with anesthetic agent-specific vaporizers.

This document applies to dedicated filling systems for anesthetic agents.

Materials of construction are not specified in this document.

Note 1.For material recommendations, see Appendix A.

Due to the unique properties of desflurane, this document does not specify the dimensions of a dedicated filling system for this anesthetic agent.

Note 2.It is encouraged to design a connection system between a dedicated anesthetic bottle connector and an anesthetic bottle with a neck ring.
