Factors governing the de

24、sign of these connectors include robustness, simplicity, ease of sterilization and ease of engagement and disengagement by hand. They should also be compatible with connectors meeting the requirements specified in ISO 5356-1 and should, if possible, eliminate the likelihood of inadvertent misconnect

25、ion, although it has to remain the responsibility of the user to check that any system in which they are used is correctly assembled before use.Screw-threaded weight-bearing connectors specified in this part of ISO 5356 can be used for attachments within the breathing system and at the common gas ou

Such connectors are intended for mounting heavy accessor

27、ies.This part of ISO 5356 specifies requirements for the following screw-threaded, weight-bearing conical connectors: 22 mm connectors; 22 mm/15 mm coaxial connectors.Requirements for the application of screw-threaded, weight-bearing conical connectors are not included in this part of ISO 5356, but

28、are or will be given in the relevant International Standards for specific medical devices and accessories.NOTE Requirements on cones and sockets are specified in ISO 5356-1.2 Normative referencesThe following referenced documents are indispensable for the application of this document.
