GB/T 45665.1-2025 Anaesthetic and respiratory equipment—Conical connectors—Part 1:Cones and sockets
Abstract
This document specifies the dimensions and measurement requirements for cone heads and cone sleeves used to connect anesthesia and respiratory equipment (such as respiratory systems, anesthetic gas purification systems, and evaporators). Therefore, cone heads and cone sleeves themselves are not considered equipment.
This document applies to cone heads and cone sleeves with sizes of 8.5 mm and 11.5 mm for neonatal and pediatric respiratory systems; cone heads and cone sleeves with sizes of 15 mm and 22 mm commonly used in respiratory systems; 22 mm locking cone sleeves (including performance requirements); 23 mm cone heads and cone sleeves for evaporators (this size is not applicable to respiratory systems); and 30 mm cone heads and cone sleeves used to connect respiratory systems and anesthetic gas purification systems.
This document does not specify the cone heads and cone sleeves required to be provided on medical devices and accessories.
This document does not include application requirements for cone heads and cone sleeves, as these requirements have already been or will be specified in relevant standards for specific medical devices and accessories.
