Anaesthetic and respiratory equipment – Conical connectors – Part 1: Cones and sockets (ISO 5356-1:2004)

Abstract

ISO 5356-1:2004 specifies dimensional and gauging requirements for cones and sockets intended for connecting anaesthetic and respiratory equipment, e.g. in breathing systems, anaesthetic-gas scavenging systems and vaporizers.

ISO 5356-1:2004 gives requirements for the following conical connectors:

• 8,5 mm sizes intended for use in paediatric breathing systems;
• 15 mm and 22 mm sizes intended for general use in breathing systems;
• 22 mm latching connectors (including performance requirements);
• 23 mm size intended for use with vaporizers, but not for use in breathing systems;
• 30 mm size intended for the connection of a breathing system to an anaesthetic gas scavenging system.

ISO 5356-1:2004 does not specify the medical devices and accessories on which these connections are to be provided.

Requirements for the application of conical connectors are not included in ISO 5356-1:2004, but are or will be given in the relevant International Standards for specific medical devices and accessories.

NOTE Requirements for screw-threaded weight-bearing conical connectors are specified in ISO 5356-2.

Anaesthetic and respiratory equipment – Conical connectors – Part 2: Screw-threaded weight-bearing connectors (ISO 5356-2:2006)

Abstract

ISO 5356-2:2012 specifies dimensional requirements for screw-threaded weight-bearing conical connectors intended for use with inhalation anaesthesia apparatus and ventilators. Such connectors are intended for mounting heavy accessories.

ISO 5356-2:2012 specifies requirements for the following screw-threaded, weight-bearing conical connectors:

• 22 mm connectors;
• 22/15 mm coaxial connectors.

Anaesthetic vaporizers – Agent-specific filling systems (ISO 5360:2006)

Abstract

ISO 5360:2012 specifies requirements, including dimensions, for agent-specific filling systems for agent-specific anaesthetic vaporizers.

ISO 5360:2012 does not specify construction materials. Because of the unique properties of desflurane, dimensions for this agent have not been specified in ISO 5360:2012.

Anaesthetic and respiratory equipment – Laryngoscopes for tracheal intubation (ISO 7376:2009)

Abstract

ISO 7376:2009 gives general requirements for laryngoscopes used for intubation, and specifies critical dimensions for the handle and lamp of hook-on type laryngoscopes. It also addresses the interchangeability of blades and handles.

It is applicable only to instruments with an internal battery-operated power source for illuminating the larynx, since electrical safety requirements can be more stringent for instruments connected to mains or external power packs.

It is not applicable to surgical instruments known by the same generic name, nor is it applicable to flexible laryngoscopes or laryngoscopes designed for surgery, laryngoscopes powered from mains electricity supply, laryngoscopes connected by light-transmitting cables to external light sources, or video laryngoscopes designed to work with an external video system.
