The purpose is to specify the connection between anesthesia and respiratory equipment (such as breathing systems, anesthetic gas purification The requirements for the dimensions and measurements of the cone head and cone sleeve of the system and evaporator). --- Part 2.Threaded load-bearing joints. The purpose is to specify the threaded load-bearing conical joints used for inhalation anesthesia equipment and ventilators Size requirements, these couplings are used to equip heavy-duty accessories. Although the cone head and cone sleeve specified in GB/T 45665.1-2025 are used for the connection of light breathing accessories, they are not suitable for supporting heavy or Fragile accessories require more robust connectors. Design factors for these connectors include strength, simplicity, ease of sterilization, and ease of manual connection and disconnection. These fittings are compatible with the cone heads and cone sleeves specified in GB/T 45665.1-2025, and although the system is checked for Proper installation is the user's responsibility; these connectors should be designed to minimize the possibility of accidental misconnection. The threaded load-bearing fittings specified in this document can be used for accessories in breathing systems and at common gas outlets. Anesthesia and respiratory equipment conical connectors Part 2.Threaded load-bearing joints1 ScopeThis document specifies the dimensional requirements for threaded load-bearing conical fittings for use in inhalation anesthesia equipment and ventilators. Type accessories. This document applies to 22mm/15mm coaxial, 22mm threaded load-bearing conical connectors. This document does not include requirements for the application of threaded load-bearing conical fittings, which have been or will be addressed in the context of specific medical devices and accessories.

NOTE 1 In practice, the ventilation system usually extends from. a) The gas supply port for the mixed gas (in some cases, particularly in ventilators, this port may be internal to the device and not compatible with other devices installed elsewhere). such as the interface on the ventilator housing), such as the common gas outlet of the anesthesia machine; b) Fresh gas inlet of the circulatory system, such as ventilator, T-tube, etc.; c) Fresh gas inlet for the artificial resuscitator. Note 2.The venting system usually extends from the outlet of the mixed gas from the APL valve, the open end of the T-piece, etc. to the atmosphere or the gas purification system. NOTE 3 Dedicated gas lines connected to the gas purification system are not considered part of the ventilation system. [Source.
