Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 7376 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment,
Subcommittee SC 2, Tracheal tubes and other equipment.
This first edition of ISO 7376 cancels and replaces ISO 7376-1:1994, ISO 7376-2:1997 and ISO 7376-3:1996,
which have been technically revised.

Introduction
This International Standard gives requirements for laryngoscopes for tracheal intubation, hereinafter referred
to as laryngoscopes, during anaesthesia, intensive care, emergency care and similar procedures.
Laryngoscopes are manufactured in several forms, including single-piece handle and blade construction, and
detachable blade and handle. In the latter case, the light source to illuminate the larynx during use is either a
lamp attached to a blade or a lamp in the handle with a light guide in the blade.
The forms and dimensions of blades for laryngoscopes are selected by the operator on the basis of clinical
judgement and are not covered by this International Standard. Annex A describes a test method for security of
lamp contact. A conventional marking system for indicating the size and form of blades is given in Annex B.
Annex C of this International Standard gives rationales for some of the clauses which are identified by the
inclusion of an asterisk (*) after the clause number.

1 Scope
This International Standard specifies general requirements for laryngoscopes and critical dimensions for the
handle and lamp of hook-on type laryngoscopes.
It is applicable only to instruments with an electrical power source for illuminating the larynx, since electrical
safety requirements may be more stringent for instruments connected to mains or external power packs.
This International Standard is not applicable to surgical instruments known by the same generic name.
This International Standard does not apply to:
a) the blade form or handle design, except for general requirements and the interchangeability aspects of
the connection between the blade and the handle;
b) the measurement and specification of the lamp illumination intensity;
c) flexible laryngoscopes, or laryngoscopes designed for surgery;
d) laryngoscopes powered from mains electricity supply;
e) laryngoscopes connected by light-transmitting cables to external light sources.
NOTE Instruments connected by light guides to an external light source may be subject to other International
Standards for endoscopes.
