CAN/CSA-Z7376:12:2012 Edition

Preface

This is the second edition of CAN/CSA-Z7376, Anaesthetic and respiratory equipment – Laryngoscopes for tracheal intubation, which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 7376 (second edition, 2009-08-15). It supersedes the previous edition published in 2007 as CAN/CSA-Z7376 (adopted ISO 376:2003).

Scope

This International Standard 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
• video laryngoscopes designed to work with an external video system

Note: Instruments connected by light guides to an external light source could be subject to other International Standards.
