Overview

EN ISO 7376:2020 - Anaesthetic and respiratory equipment: Laryngoscopes for tracheal intubation specifies safety, design and performance requirements for non‑flexible laryngoscopes that use internal battery‑operated light sources to illuminate the larynx during intubation. Adopted by CEN as EN ISO 7376:2020, this third edition updates the 2009 version and aligns with modern LED luminaires and current electrical safety practice.

The standard is device‑specific and covers critical dimensions for handles and blades with interchangeable hook‑on fittings, illumination minimums, structural strength and rigidity, and manufacturer information (marking, cleaning, disinfection, sterilization and instructions for use). It does not apply to flexible laryngoscopes, surgical laryngoscopes, mains‑powered devices, fibre‑optic/light‑guide systems connected to external light sources, or video laryngoscopes with integrated/attached video systems.

Key Topics

• Scope and exclusions: battery‑powered, non‑flexible blade laryngoscopes only; explicit list of non‑applicable device types.
• Design requirements: materials, ergonomic and dimensional requirements for handles and blades (sizes are designated for intended patient demographics).
• Electrical safety and performance: internal battery safeguards (including measures to prevent current surges from batteries > 3.6 V), electrical contacts, optical output (minimum illumination), and conformance tests.
• Mechanical tests: rigidity and strength tests for blades and handles; test methods for illumination, rigidity and strength appear in Annex B.
• Cleaning and sterilization: requirements and instructions manufacturers must provide to ensure reprocessing safety and device longevity.
• Documentation and marking: required labeling, size designation and instructions for intended patient groups and safe use.

Applications

EN ISO 7376:2020 is used by:

• Medical device manufacturers designing, testing and certifying battery‑powered laryngoscopes.
• Clinical engineers and procurement teams verifying product compliance and interoperability (blade/handle fittings and dimensions).
• Regulatory and conformity assessment bodies evaluating electrical and mechanical safety claims.
• Anesthesia providers and hospital sterilization units relying on manufacturer instructions for cleaning, disinfection and selection of appropriately sized blades for patient demographics.

Adoption improves device safety, interoperability and consistency in clinical performance for tracheal intubation instruments.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Agreement).
This third edition cancels and replaces the second edition (ISO 7376:2009), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— the layout has changed to align with ISO 18190:2016;
— removal of the requirements for filament luminaires, which are now almost entirely replaced by LED
luminaires;
— additional requirement to prevent current surges from batteries with a rated voltage exceeding 3,6 V;
— test methods have been rationalized;
— each requirement is now followed by a conformance requirement;
— the strength requirement has been extended to handles;
— environmental conditions during transport, storage and normal use are now referenced to
IEC 60601-1-12.

ISO 7376:2020(E)
Introduction
Laryngoscopes are manufactured in several forms. There are, for example, single-piece laryngoscopes,
non-user-detachable hinged laryngoscope blades, or detachable hinged laryngoscope blades and handles.
In the latter case, the light source for illuminating the larynx during use is either a luminaire fixed in
the laryngoscope blade or a luminaire in the handle with a light guide in the laryngoscope blade. The
minimum light output from the laryngoscope is specified.
Laryngoscope blades are defined and marked by size designation (see Table 2), suitable for the patient
demographic for which they are designed and ranges from small, premature infants to extra-large
adults. Because there are so many variations, the length of laryngoscope blade is disclosed on the
packaging to allow an informed decision by the operator to select the most appropriate instrument for
intubation. Annex B describes test methods for illumination, rigidity and strength.
Throughout this document the following print types are used:
— Requirements and definitions: roman type;
— Conformance tests: italic type;
— Informative material appearing outside of tables, such as notes, examples and references: smaller
type. The Normative text of tables is also in smaller type;
— Terms defined in Clause 3: italics.
An asterisk (*) as the first character of a title or at the beginning of a paragraph or table title indicates
that there is guidance or rationale related to that item in Annex A.
