Introduction
In the 1990s, concern grew regarding the proliferation of medical devices fitted with Luer connectors
[1]
as specified in the ISO 594 series and the reports of patient death or injury arising from unintended
connections that resulted in the inappropriate delivery of fluids and gases via incorrect routes. In addition to
clinical and workplace protocols and warnings, attention was turned to engineering solutions to reduce the
probability of wrong route administration of liquids and gases.
Concerns regarding the use of Luer connectors with enteral feeding tubes and gas sampling and gas delivery
systems were raised with CEN Bureau Technique (CEN/BT) and the European Commission. In November
1997, the newly created CEN Healthcare Forum (CHeF) steering group set up a Forum Task Group (FTG) to
consider the problem.
[9]
The FTG produced CEN Report, CEN/CR 13825, in which they concluded that there is a problem arising
from the use of a single connector design to several different applications. In a coronary care unit, there could
be as many as 40 Luer connectors on the medical devices used with a single patient until the use of connectors
defined in the ISO and IEC 80369 documents started to be established. Therefore, it is not surprising that
unintended connections were made.
Medical devices have, for many years, followed the established principle of “safety under single fault
conditions.” Simply stated, this means that a single fault should not result in an unacceptable risk. This
[6]
principle is embodied in the requirements of numerous medical device standards. Extending this principle
to the use of Luer connectors (i.e. that an unintended connection should not result in an unacceptable risk to
a patient) the FTG recommended that the Luer connector should be restricted to medical devices intended
to be connected to the vascular system or a hypodermic syringe. In addition, the FTG recommended that
new designs of small-bore connectors should be developed for other applications, and these should be non-
interconnectable with Luer connectors and each other.
[10]
International medical device regulators forum (IMDRF), GRRP N47:2024, Essential Principle 5.1.3,
addresses this type of problem:
Risk control measures adopted by manufacturers for the design and manufacture of the medical device
and IVD medical device should conform to safety principles, taking account of the generally acknowledged
state of the art. When risk reduction is required, manufacturers should control risks so that the residual
risk associated with each hazard as well as the overall re

that resulted in the inappropriate delivery of fluids and gases via incorrect routes. In addition to clinical and

Concerns regarding the use of Luer connectors with enteral feeding tubes and gas sampling and gas delivery

Medical devices have, for many years, followed the established principle of “safety under single fault

connected to the vascular system or a hypodermic syringe. In addition, the FTG recommended that new
designs of small-bore connectors should be developed for other applications, and these should be non-
interconnectable with Luer connectors and each other.
[10]]
International medical device regulators forum (IMDRF), GRRP N47:2024, Essential Principle 5.1.3,
addresses this type of problem:
Risk control measures adopted by manufacturers for the design and manufacture of the medical device
and IVD medical device should conform to safety principles, taking account of the generally
acknowledged state of the art. When risk reduction is required, manufacturers should control risks so
that the residual risk associated with each hazard as well as the overall residual risk is judged
acceptable. In selecting the most appropriate solutions, manufacturers should, in the following order of
priority:
a) eliminate or appropriately reduce risks through safe design and manufacture;
b) where appropriate, take adequate protection measures, including alarms if necessary, in relation to
risks that cannot be eliminated;
c) provide information for safety (warnings/precautions/contra-indications) and, where appropriate,
training to users.
It is understood that small-bore connector systems cannot be designed to overcome all chances of unintended
connections with the potential for wrong route administration or to eliminate deliberate misuse. With these
application-specific connectors now available, the risk of unintended connections and wrong route
administration is greatly reduced thereby improving patient safety. Introduction of medical devices and
accessories utilizing these small-bore connectors is progressing albeit slowly.
The risks associated with unintended connections and subsequent wrong route administration of liquids and
gases cannot be fully assessed until these small-bore connectors are part of a medical device or accessory.
Therefore, the intended applications specified are recommendations. It is expected that particular medical
vi
device standards will reference the connectors from the relevant parts of the ISO and IEC 80369 series if
considered appropriate.
This document contains the general requirements to reduce connections between small-bore connectors used
in different applications as well as specifying those applications.
It specifies the general requirements and test methods for assessing the non-interconnectable characteristics
of small-bore connectors within the ISO and IEC 80369 series.
The Luer connector as originally defined in the withdrawn ISO 594 series has been widely used on many
medical devices and accessories and in a wide range of clinical applications for many years. The clinical
applications that present the highest risk to a patient from wrong route administration of liquids and gases
have been identified and are those included in the application parts of the ISO and IEC 80369 series.
ISO 80369-7, which replaces the ISO 594 series (i.e. the Luer connector), is intended for use with intravascular
or hypodermic applications.
However, there are currently medical devices and accessories which incorporate a Luer connector, but do not
fall into any of the applications specified by the ISO and IEC 80369 series. There are also some medical devices
and accessories within the app

Introduction
Dans les années 1990, la multiplication des dispositifs médicaux équipés de raccords Luer, tels que spécifiés
dans la série ISO 594, et les rapports faisant état de décès ou de dommages corporels aux patients dus à des
raccordements non intentionnels ayant entraîné l'administration inappropriée de liquides et de gaz par des
voies inappropriées ont suscité des inquiétudes croissantes. Outre les protocoles cliniques, et les protocoles
et avertissements applicables sur le lieu de travail, l'attention a été portée sur les solutions d'ingénierie
visant à réduire la probabilité d'une administration de liquides et de gaz par une voie inappropriée.
Le CEN/BT et la Commission européenne ont exprimé leur inquiétude concernant l'utilisation de
raccords Luer pour les sondes d'alimentation entérale et les systèmes de prélèvement et de distribution de
gaz. En novembre 1997, le groupe pilote CHeF, nouvellement créé, a fondé un groupe d'étude du forum (FTG)
pour se pencher sur le problème.
[7]
Le FTG a rédigé le rapport CEN CR 13825 , qui conclut à l'existence d'un problème lié à l'utilisation d'un
même modèle de raccord pour plusieurs applications différentes. Dans une unité de soins intensifs de
cardiologie, il pouvait y avoir jusqu'à 40 raccords Luer sur les dispositifs médicaux utilisés pour un seul
patient, avant que l'utilisation des raccords définie dans les normes ISO et IEC 80369 ne commence à
s'imposer. Dans ces conditions, il n'est pas étonnant qu'il y ait eu des raccordements non intentionnels.
Depuis de nombreuses années, les dispositifs médicaux fonctionnent selon le principe établi de la « sécurité
en conditions de premier défaut ». En clair, cela signifie qu'il convient qu'une seule erreur n'entraîne pas de
risque inacceptable. Ce principe sous-tend les exigences de nombreuses normes relatives aux dispositifs
[5]
médicaux . En étendant à l'utilisation de raccords Luer ce principe (selon lequel il convient qu'un
raccordement non intentionnel n'entraîne pas de risque inacceptable pour un patient), le FTG a recommandé
que l'usage du raccord Luer soit limité aux dispositifs médicaux destinés à être raccordés au système
vasculaire ou à une seringue hypodermique. En outre, il a été recommandé par le FTG que de nouveaux
modèles de raccords de petite taille soient développés pour d'autres applications, et que ces nouveaux
modèles soient non raccordables aux raccords Luer et non raccordables entre eux.
L'ISO 16142-1:2016 traite de ce type de problème dans son Principe essentiel 2 du Tableau B.1.
Il convient que les solutions adoptées par le fabricant pour la conception et la fabrication du
dispositif médical soient conformes aux principes de sécurité, compte tenu de l'état de la
technique généralement reconnu. Lorsque la réduction des risques se révèle nécessaire, il
convient que le fabricant maîtrise les risques de manière que le risque résiduel lié à chaque
phénomène dangereux soit jugé acceptable. Il convient que le fabricant applique les principes
suivants dans l'ordre de priorité indiqué :
a) identifier les phénomènes dangereux connus ou prévisibles et estimer les risques associés,
aussi bien dans le cadre de l'emploi prévu que dans celui d'un mésusage prévisible ;
b) éliminer autant que possible les risques grâce à la sécurité inhérente à la conception et à la
fabrication ;
c) réduire autant que possible les risques restants en prenant des mesures de protection
adéquates, y compris par le biais d'alarmes, ou en utilisant les informations relatives à la
sécurité ;
d) informer les utilisateurs des éventuels risques résiduels.

Il est admis qu'il n'est pas possible de concevoir des systèmes de raccords de petite taille permettant d'éviter
tout risque de raccordements non intentionnels et d'administration par voie inappropriée, ni d'empêcher des
mésusages délibérés. Maintenant qu'il existe des raccords spécifiques à différentes applications,
l'environnement est beaucoup plus sûr pour les patients et la probabilité de raccordements non intentionnels
est réduite, ce qui diminue le risque d'administration par voie inappropriée et améliore, en conséquence, la
sécurité des patients. Bien que lent, le déploiement de dispositifs médicaux et d'accessoires utilisant ces
raccords de petite taille progresse.
Les risques associés aux raccordements non intentionnels et à l'administration qui s'ensuit de liquides et de
gaz par voie inappropriée ne peuvent être entièrement évalués, tant que ces raccords de petite taille ne sont
pas installés sur un dispositif médical ou un accessoire. C'est pourquoi les spécifications relatives aux
applications prévues sont des recommandatio
