ISO 17664-1:2021(E)
Introduction

This document applies to manufacturers of those medical devices that are intended to be cleaned,

disinfected and/or sterilized by the processor to be made ready for use. This includes:

— Medical devices that are intended for reuse and require processing to take them from their state

after clinical use to the state of being ready for their next use. This may include one or more of

cleaning, disinfection and sterilization.

— Single-use medical devices that require processing before use and are intended to be used in a clean

and/or disinfected and/or sterile state.

Significant advances in technology and knowledge have resulted in the development of complex medical

devices to support the delivery of health care to patients. These advances have led to medical devices

being designed that are potentially more difficult to clean, disinfect and/or sterilize.

Cleaning, disinfecting and sterilizing technologies have also undergone significant change in the past

decade, resulting in new systems and approaches that can be applied in the processing of medical

devices. This has led to a greater appreciation of the need for validation of processing, including

cleaning, disinfection and/or sterilization in order to ensure that medical devices are effectively

processed. These developments have led to the need to ensure that manufacturers of medical devices

provide adequate instructions that support end users to undertake safe and effective processing of

medical devices, utilizing the available equipment and processes.

A medical device requiring processing is supplied with detailed processing instructions in order to

ensure that, when followed correctly, the risks of transmission of infectious agents are minimized. In

addition, effective processing minimizes the risk of other adverse effects on medical devices.

Cleaning is an important step in rendering a used medical device safe for subsequent use. Failure to

remove contaminants (e.g. blood, tissues, microorganisms, cleaning agents and lubricants) from the

surfaces of a medical device could compromise the correct functioning of the medical device, its safe

use and (if required) any subsequent disinfection process, sterilization process or both. Single-use

medical devices provided by the medical device manufacturer for processing prior to use can also

require cleaning prior to further processing.

After cleaning, other factors can affect the safe and effective use of a medical device. For example,

procedures for inspection and functional testing can be necessary to ensure that a medical device

does not pose a safety risk when used. Manufacturers of medical devices can assist users by providing

instructions on how this inspection and testing should be performed.

Manufacturers of medical devices that are to be processed have a responsibility to ensure that the

design of the medical devices facilitates achievement of effective processing. This includes consideration

of commonly available validated processes; examples are shown in Annex A, which can be used as a

guide to validate procedures.

ISO 17664-1:2021(F)
Introduction

Le présent document s’applique aux fabricants de dispositifs médicaux prévus pour être soumis à un

procédé de nettoyage, de désinfection et/ou de stérilisation par l’opérateur de procédé, afin de les

rendre « prêts à l’emploi ». Sont inclus:

— les dispositifs médicaux destinés à être réutilisés et requérant un traitement pour les faire passer

de leur état « après une utilisation clinique » à l’état « prêt à être réutilisé ». Cela peut inclure une ou

plusieurs opérations de nettoyage, désinfection et stérilisation;

— les dispositifs médicaux à usage unique requérant un traitement avant utilisation et destinés à être

utilisés dans un état « nettoyé et/ou désinfecté et/ou stérile ».

Les importants progrès réalisés à la fois sur le plan des technologies et des connaissances ont permis

de développer des dispositifs médicaux complexes qui contribuent aux soins de santé des patients. Ces

avancées ont conduit à la conception de dispositifs médicaux potentiellement plus difficiles à nettoyer,

désinfecter et/ou stériliser.

Les technologies de nettoyage, de désinfection et de stérilisation ont également considérablement

évolué au cours des dix dernières années, aboutissant à de nouveaux systèmes et de nouvelles approches

applicables au traitement des dispositifs médicaux. Ces changements ont permis une meilleure prise en

compte du besoin de validation des procédés, notamment du nettoyage, de la désinfection, et/ou de la

stérilisation, afin d’assurer que les dispositifs médicaux sont traités efficacement. Ils ont également créé

le besoin de s’assurer que les fabricants de dispositifs médicaux fournissent des instructions adéquates,

aidant les utilisateurs finaux à traiter efficacement et en toute sécurité les dispositifs médicaux, en

utilisant les équipements et procédés disponibles.

Un dispositif médical requérant un traitement est fourni avec des instructions de traitement détaillées

afin d’assurer que, si celles-ci sont suivies correctement, les risques de transmission d’agents infectieux

sont réduits au minimum. En outre, un traitement efficace réduit au minimum le risque d’autres effets

négatifs sur les dispositifs médicaux.

Le nettoyage est une étape importante pour permettre la réutilisation en toute sécurité d’un dispositif

médical utilisé. Les contaminants (par exemple, sang, tissus, micro-organismes, agents de nettoyage

et lubrifiants) qui ne sont pas éliminés des surfaces du dispositif médical sont susceptibles de

compromettre le fonctionnement correct du dispositif médical, son utilisation en toute sécurité et (le

cas échéant) tout procédé de désinfection ou de stérilisation, ou les deux. Les dispositifs médicaux à

usage unique fournis par le fabricant de dispositifs médicaux de sorte qu’ils soient traités avant leur

utilisation peuvent également exiger un nettoyage avant toute poursuite du traitement.

Après le nettoyage, d’autres facteurs peuvent affecter l’utilisation sûre et efficace d’un dispositif médical.

Par exemple, des procédures de contrôle et des essais de fonctionnement peuvent s’avérer nécessaires

pour assurer qu’un dispositif médical ne présente pas de risque pour la sécurité à l’utilisation. Les

fabricants de dispositifs médicaux peuvent aider les utilisateurs en leur fournissant des instructions

sur la manière dont il convient d’effectuer ces contrôles et essais.

Il est de la responsabilité des fabricants de dispositifs médicaux requérant un traitement d’assurer que

leur conception facilite l’obtention dudit traitement avec efficacité. Cela inclut la prise en compte des

procédés validés communément disponibles; des exemples sont fournis dans l’Annexe A, qui peut être

utilisée comme guide pour valider des modes opératoires.

Introduction

This document applies to manufacturers of those medical devices that are intended to be cleaned,

disinfected, sterilized or a combination of all three by the processor to be made ready for use. This

includes:

— Medical devices that are intended for reuse and require processing to take them from their state

after clinical use to the state of being ready for their next use. This may include one or more of

cleaning, disinfection and sterilization.

— Single-use medical devices that require processing before use and are intended to be used in a clean,

disinfected or sterile state, or a combination of all three.

Significant advances in technology and knowledge have resulted in the development of complex medical

devices to support the delivery of health care to patients. These advances have led to medical devices

being designed that are potentially more difficult to clean, disinfect or sterilize.

Cleaning, disinfecting and sterilizing technologies have also undergone significant change in the past

decade, resulting in new systems and approaches that can be applied in the processing of medical

devices. This has led to a greater appreciation of the need for validation of processing, including

cleaning, disinfection, sterilization or a combination of all three in order to ensure that medical devices

are effectively processed. These developments have led to the need to ensure that manufacturers of

medical devices provide adequate instructions that support end users to undertake safe and effective

processing of medical devices, utilizing the available equipment and processes.

A medical device requiring processing is supplied with detailed processing instructions in order to

ensure that, when followed correctly, the risks of transmission of infectious agents are minimized. In

addition, effective processing minimizes the risk of other adverse effects on medical devices.

Cleaning is an important step in rendering a used medical device safe for subsequent use. Failure to

remove contaminants (e.g. blood, tissues, microorganisms, cleaning agents and lubricants) from the

surfaces of a medical device could compromise the correct functioning of the medical device, its safe

use and (if required) any subsequent disinfection process, sterilization process or both. Single-use

medical devices provided by the medical device manufacturer for processing prior to use can also

require cleaning prior to further processing.

After cleaning, other factors can affect the safe and effective use of a medical device. For example,

procedures for inspection and functional testing can be necessary to ensure that a medical device

does not pose a safety risk when used. Manufacturers of medical devices can assist users by providing

instructions on how this inspection and testing should be performed.

Manufacturers of medical devices that are to be processed have a responsibility to ensure that the

design of the medical devices facilitates achievement of effective processing. This includes consideration

of commonly available validated processes; examples are shown in Annex A, which can be used as a

guide to validate procedures.
