Biocompatibility evaluation of breathing gas pathways in healthcare applications - Part 2: Tests for emissions of particulate matter (ISO 18562-2:2024)
This document specifies tests for the emissions of particulate matter from the gas pathways of a medical device, its parts or accessories, which are intended to provide respiratory care or supply substances via the respiratory tract to a patient in all environments. The tests of this document are intended to quantify particles from 0,25 µm diameter to 10 µm diameter that are emitted by the medical device, its parts or accessories into the respirable gas stream. This document establishes acceptance criteria for these tests.
This document does not address nanoparticles. Insufficient data exist to establish exposure limits for particles less than 0,25 µm diameter.
This document does not address particles larger than 10 µm diameter. These particles are deposited in the nasal cavity. Additional information can be needed for medical devices or accessories that bypass the nose. This is outside the scope of this document but can be required by some authorities having jurisdiction.
This document therefore adopts the same approach as the US Environmental Protection Agency (EPA) in setting limits based solely on particle size and not their chemistry.
This document addresses potential contamination of the gas stream arising from the gas pathways, which is then conducted to the patient.
This document applies over the expected lifetime of the medical device in normal use and takes into account the effects of any intended processing.
This document does not address biological evaluation of the particles that are deliberately released by a nebulizer (i.e. the therapeutic agent).
This document does not address biological evaluation of the surfaces of gas pathways that have direct contact with the patient. The requirements for direct contact surfaces are found in the ISO 10993 series.
Medical devices, parts or accessories, containing gas pathways that are addressed by this document, include, but are not limited to, ventilators, anaesthesia workstations (including gas mixers), breathing systems, oxygen conserving devices, oxygen concentrators, nebulizers, low-pressure hose assemblies, humidifiers, heat and moisture exchangers, respiratory gas monitors, respiration monitors, masks, medical respiratory personal protective equipment, mouth pieces, resuscitators, breathing tubes, breathing systems filters, Y-pieces, and any breathing accessories intended to be used with such devices. The enclosed chamber of an incubator, including the mattress, and the inner surface of an oxygen hood are considered to be gas pathways and are also addressed by this document.
This document does not address contamination already present in the gas supplied from the gas sources while medical devices are in normal use.
EXAMPLE Contamination arriving at the medical device from gas sources such as medical gas pipeline systems (including the non-return valves in the pipeline outlets), outlets of pressure regulators connected or integral to a medical gas cylinder or room air taken into the medical device is not addressed by ISO 18562 (all parts).
Beurteilung der Biokompatibilität der Atemgaswege bei medizinischen Anwendungen - Teil 2: Prüfungen für Emissionen von Partikeln (ISO 18562-2:2024)
ANMERKUNG Abschnitt A.2 enthält eine Anleitung oder Begründung zu diesem Abschnitt.
Dieses Dokument legt Prüfungen für die Emissionen von Partikeln aus den Gaswegen eines Medizinprodukts sowie von dessen Teilen oder Zubehör fest, die für die Beatmung oder die Zufuhr von Stoffen über die Atemwege zum Patienten in allen Umgebungen vorgesehen sind. Die Prüfungen in diesem Dokument dienen dazu, Partikel mit einem Durchmesser von 0,25 µm bis 10 µm, die von einem Medizinprodukt, dessen Teilen oder Zubehör in den atembaren Gasstrom abgegeben werden, zu quantifizieren. Dieses Dokument erstellt Akzeptanzkriterien für diese Prüfungen.
Dieses Dokument behandelt keine Nanopartikel. Für die Festlegung der Expositionsgrenzwerte für Partikel mit einem Durchmesser von weniger als 0,25 µm stehen keine ausreichenden Daten zur Verfügung.
In diesem Dokument werden keine Partikel abgedeckt, deren Durchmesser mehr als 10 µm beträgt. Diese Partikel werden in der Nasenhöhle abgesetzt. Zusätzliche Informationen können erforderlich werden für ein Medizinprodukt oder Zubehör, das die Nase umgeht. Dies liegt außerhalb des Anwendungsbereichs dieses Dokuments, kann aber von einigen zuständigen Behörden angefordert werden.
Dieses Dokument wendet daher denselben Ansatz wie die US Environmental Protection Agency (EPA) an, die Grenzwerte, ausschließlich auf Basis der Partikelgröße und nicht ihrer chemischen Zusammensetzung festlegt.
Dieses Dokument behandelt die potenzielle Verunreinigung des Gasstroms aus den Gaswegen, die anschließend dem Patienten zugeführt wird.
Dieses Dokument ist anwendbar für die zu erwartete Lebensdauer des Medizinprodukts bei bestimmungsgemäßem Gebrauch und berücksichtigt die Auswirkungen jeder beabsichtigten Aufbereitung.
Dieses Dokument behandelt nicht die biologische Beurteilung der Partikel, die absichtlich von einem Vernebler freigesetzt werden (d. h. das Therapeutikum).
Dieses Dokument behandelt nicht die biologische Beurteilung der Oberflächen von Gaswegen in direktem Kontakt mit dem Patienten. Die Anforderungen an Oberflächen in direktem Kontakt sind in der Normenreihe ISO 10993 enthalten.
Medizinprodukte, Teile oder Zubehör, die Gaswege enthalten, die in diesem Dokument behandelt werden, umfassen unter anderem Beatmungsgeräte, Anästhesie-Arbeitsplätze (einschließlich Gasmischern), Atemsysteme, Sauerstoff-Dosiersysteme, Sauerstoff-Konzentratoren, Vernebler, Niederdruck-Schlauchsysteme, Anfeuchter, Wärme- und Feuchtigkeitsaustauscher, Atemgas-Überwachungsgeräte, Atmungsüberwachungsgeräte, Masken, medizinische persönliche Atemschutzausrüstung, Mundstücke, Wiederbelebungsgeräte, Atemschläuche, Atemsystemfilter, Y-Stücke und jedes für den Einsatz mit Geräten vorgesehene Atemzubehör. Die umschlossene Kammer eines Inkubators einschließlich der Matratze und der inneren Oberfläche einer Sauerstoffhaube gelten als Gaswege und werden ebenfalls in diesem Dokument behandelt.
Dieses Dokument behandelt nicht die bereits in dem aus der Gasquelle zugeführten Gas vorhandene Verunreinigung während des bestimmungsgemäßen Gebrauchs von Medizinprodukten.
BEISPIEL In das Medizinprodukt eintretende Verunreinigungen aus den Gasquellen wie etwa Rohrleitungssystemen für medizinische Gase (einschließlich Rückschlagventilen an den Leitungsauslässen), Ausgänge von Druckminderern, die mit Flaschen für medizinische Gase verbunden oder in diese integriert sind, oder in das Medizinprodukt eintretende Raumluft werden nicht in ISO 18562 (alle Teile) behandelt.
Évaluation de la biocompatibilité des chemins de gaz respiratoire utilisés dans le domaine de la santé - Partie 2: Essais concernant les émissions de matières particulaires (ISO 18562-2:2024)
Le présent document spécifie les essais concernant les émissions des matières particulaires provenant des chemins de gaz utilisés dans un dispositif médical, ses parties ou ses accessoires, qui sont destinés à dispenser des soins respiratoires ou à fournir des substances par les voies respiratoires à un patient dans tous les types d’environnements. Les essais contenus dans le présent document sont destinés quantifier les particules dont le diamètre est compris entre 0,25 µm et 10 µm et qui sont émises par le dispositif médical, ses parties ou ses accessoires dans le flux de gaz respirable. Le présent document établit les critères d’acceptation de ces essais.
Le présent document ne traite pas des nanoparticules. Il n’existe pas de données suffisantes afin d’établir des limites d’exposition pour les particules d’un diamètre inférieur à 0,25 µm.
Le présent document ne traite pas des particules d’un diamètre supérieur à 10 µm. Ces particules se déposent dans la cavité nasale. Des informations supplémentaires peuvent se révéler nécessaires pour les dispositifs médicaux ou les accessoires qui ne passent pas par le nez. Ce point est en dehors du domaine d’application du présent document, mais il peut être requis par certaines autorités compétentes.
Le présent document adopte donc la même approche que l’US Environmental Protection Agency (EPA) (Agence américaine de protection de l’environnement) en établissant des limites fondées uniquement sur la taille des particules et non pas sur leurs propriétés chimiques.
Le présent document traite de la contamination potentielle du flux gazeux qui provient des chemins de gaz et qui est ensuite acheminé jusqu’au patient.
Le présent document s’applique tout au long de la durée de vie prévue du dispositif médical en utilisation normale et prend en compte les effets associés à tout traitement prévu.
Le présent document n’aborde pas l’évaluation biologique des particules qui sont intentionnellement libérées par un nébuliseur (c’est-à-dire l’agent thérapeutique).
Le présent document ne traite pas de l’évaluation biologique des surfaces des chemins de gaz qui sont en contact direct avec le patient. Les exigences relatives aux surfaces en contact direct sont indiquées dans la série de normes ISO 10993.
Les dispositifs médicaux, leurs parties ou accessoires, contenant des chemins de gaz et faisant l’objet du présent document, comprennent, mais sans s’y limiter, les ventilateurs, les systèmes d’anesthésie (y compris les mélangeurs de gaz), les systèmes respiratoires, les économiseurs d’oxygène, les concentrateurs d’oxygène, les nébuliseurs, les flexibles de raccordement à basse pression, les humidificateurs, les échangeurs de chaleur et d’humidité, les moniteurs de gaz respiratoires, les moniteurs de respiration, les masques, les équipements médicaux de protection respiratoire individuelle, les embouts buccaux, les appareils de réanimation, les tubes respiratoires, les filtres des systèmes respiratoires, les raccords en Y ainsi que tous les accessoires respiratoires destinés à être utilisés avec ces dispositifs. La chambre fermée d’un incubateur, y compris le matelas et la surface intérieure d’une cloche de Hood, est considérée comme un chemin de gaz et est également couverte par le présent document.
Le présent document ne traite pas de la contamination déjà présente dans le gaz provenant des sources de gaz lors d’une utilisation normale des dispositifs médicaux.

Introduction
This document is intended to protect patients connected to medical devices from excessive amounts of
particulate matter that arises from within gas pathways of medical devices.
This document is intended to cover the biological evaluation of gas pathways of medical devices within
a risk management process, as part of the overall medical device evaluation and development. This
approach combines the review and evaluation of existing data from all sources with, where necessary,
the selection and application of additional tests.
[2]
In general, the ISO 10993 series is intended to cover the biological evaluation of medical devices.
However, the ISO 10993 series does not appropriately address the biological evaluation of the gas
pathways of medical devices. For example, the ISO 10993 tests do not evaluate inspired particulate
matter.
It is not within the scope of this document to address contamination arising from the source of the
breathing gases entering such medical devices, but rather to address only the potential contamination
generated from within the medical device itself. This contamination might be from the original
manufacturing process or be generated by the medical device itself during use.
This document is concerned with particulate matter that could be conveyed to the patient by the
breathing gases. The smaller the particle, the deeper into the lungs it can penetrate and the longer it
takes the body to eliminate it. Originally, the main health concerns with regard to particulate matter
were focused on respiratory health, but now there is emerging evidence of effects on the cardiovascular
system as well.
The tests for the presence of particulate matter generated by respiratory medical devices are based on
standard laboratory practice and require no advanced techniques or equipment.
The acceptable levels of contamination are based on worldwide published health data for particulates.
It is accepted that there is no point in setting a level that is lower than that found in air that people
might breathe every day of their lives.
