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 part 1 of GB/T 45665 "Conical connectors for anesthesia and respiratory equipment". GB/T 45665 has been published as follows part.

--- Part 1: Cone head and cone sleeve;

--- Part 2: Threaded load-bearing joints.

This document is equivalent to ISO 5356-1:2015 "Conical connectors for anesthetic and respiratory equipment - Part 1: Cone heads and sleeves".

A new chapter "Terms and Definitions" has been added to this document.

Introduction

GB/T 45665 "Conical connectors for anesthetic and respiratory equipment" is intended to consist of two parts.

--- Part 1: Cone head and cone sleeve. The purpose is to ensure that it is used to connect anesthesia and respiratory equipment (such as breathing systems, anesthetic gas purification System and evaporator) cone head and cone sleeve size and measurement requirements.

--- Part 2: Threaded load-bearing joints. The purpose is to ensure the threaded load-bearing conical joints used in inhalation anesthesia equipment and ventilators Size requirements, these couplings are used to equip heavy-duty accessories.

Clinically, it may be necessary to connect multiple respiratory accessories used in anesthesia and respiratory equipment together to form a suitable respiratory system.

Other medical equipment such as humidifiers or spirometers are often connected to the breathing system, which can also be connected to anesthesia gas these devices are often connected by cone heads and cone sleeves. If these connections lack standardization, different manufacturers this document specifies the requirements for cones and cone sleeves used in anesthesia and respiratory equipment.

and size.

It is important to consider that the cone connection needs to be secure but not prevent the operator from disconnecting it.

To minimize the risk of accidental uncoupling of the 22 mm connector, use Locking cone sleeve.

Appendix A contains illustrations and diagrams of plug and ring gauges used to inspect non-metallic tapers and sleeves. Appendix B, Appendix C, Appendix D

The test method for locking taper sleeves is described in Appendix E. It contains diagrams and charts of plug and ring gauges used for checking metal tapers and sleeves.

Note F gives recommendations for safety testing of locking taper sleeves.

The dimensions and tolerances of the taper head and taper sleeve in Figure 1 are specified in GB/T 15754.

Anesthesia and respiratory equipment conical connectors Part 1: Cone heads and sleeves

1 Scope

This document specifies the specifications for cones and cone sleeves used to connect anesthetic and respiratory equipment (such as breathing systems, anesthetic gas purification systems and vaporizers).

Therefore, the cone head and cone sleeve themselves are not considered as equipment.

This document applies to 8.5mm and 11.5mm cone heads and cone sleeves for neonatal and pediatric respiratory systems, and general use in respiratory systems.

15mm and 22mm cone heads and cone sleeves, 22mm locking cone sleeves (including performance requirements), 23mm cone sleeves for evaporators Head and cone sleeve (this specification is not applicable to breathing system) and 30mm cone for connection of breathing system and anesthesia gas purification system Head and cone sleeve.

This document does not specify the cones and sleeves that need to be provided on medical devices and accessories.

This document does not include the application requirements for cones and sleeves. These requirements are or will be included in the relevant standards for specific medical devices and accessories.

Given.

NOTE. ISO 5356-2 specifies the requirements for threaded load-bearing joints.
