Transportable liquid oxygen systems for medical use - Particular requirements (ISO 18777:2005)
This International Standard specifies requirements for the safety and essential performance of transportable liquid oxygen systems which are used as a supply source for oxygen therapy. These devices usually consist of a portable unit to be carried by or with the patient whilst in use and the vessel used to refill the portable unit. These devices are mostly used in home care applications and in health care facilities/institutions. These devices are often used without professional supervision. Liquid oxygen vessels used as a supply source for oxygen pipeline systems are excluded from this International Standard. The requirements of this International Standard which replace or modify the requirements of IEC 60601-1:1998 and its Amendments 1 (1991) and 2 (1995) are intended to take precedence over the corresponding general requirements.

Änderungen (am Ende von 1.1 ergänzen):
1.1
Diese Internationale Norm legt Anforderungen für die Sicherheit und die wesentlichen Leistungsmerkmale von Flüssigsauerstoffsystemen fest, die als Versorgungsquelle für die Sauerstofftherapie verwendet werden. Diese Geräte bestehen üblicherweise aus einer tragbaren Einheit, die durch den oder mit dem Patienten während des Gebrauchs getragen wird, und dem zur Nachfüllung der tragbaren Einheit dienenden Gefäß. Diese Geräte werden vorwiegend bei der häuslichen Pflege und in Einrichtungen des Gesundheitswesens verwendet. Sie werden oft ohne Überwachung durch Fachpersonal verwendet.
Flüssigsauerstoffbehälter, die als Versorgungsquelle für Rohrleitungssysteme verwendet werden, fallen nicht in den Anwendungsbereich dieser Internationalen Norm.
Die Anforderungen dieser Internationalen Norm, die die Anforderungen von IEC 60601-1:1988 mit ihren Änderungen 1 (1991) und 2 (1995) ersetzen oder ändern, haben Vorrang gegenüber den entsprechenden allgemeinen Anforderungen.

Systèmes transportables d'oxygène liquide à usage médical - Exigences particulières (ISO 18777:2005)
L'ISO 18777:2005 spécifie les prescriptions de sécurité et de performance essentielles applicables aux systèmes transportables d'oxygène liquide utilisés comme source d'alimentation pour l'oxygénothérapie. Ces appareils se composent généralement d'une unité portative transportée par le patient ou avec celui-ci en cours d'utilisation et d'un récipient utilisé pour remplir l'unité portative. Ces appareils sont pour la plupart utilisés dans les applications de soins à domicile et dans les établissements de santé. Ces appareils sont souvent utilisés sans surveillance professionnelle.
Les cuves d'oxygène liquide utilisées comme source d'alimentation pour les systèmes de distribution d'oxygène sont exclues de la présente Norme internationale.

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 18777 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 215, Respiratory and anaesthetic equipment, in collaboration with Technical Committee ISO/TC 121,
Anaesthetic and respiratory equipment, Subcommittee SC 3, Lung ventilators and related equipment, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

Introduction
This International Standard specifies requirements for liquid oxygen systems which are used as a source of
supply for oxygen therapy.
Annex AA contains a rationale for some of the requirements. It is included to provide additional insight into the
committee’s reasoning that led to a requirement and identifying the hazards that the requirement addresses.
Clauses and subclauses marked with * after their number have corresponding rationale contained in
Annex AA.
This International Standard is a Particular Standard based on IEC 60601-1:1988, including Amendments 1
(1991) and 2 (1995), hereafter referred to as the General Standard. The General Standard is the basic
standard for the safety of all medical electrical equipment used by or under the supervision of qualified
personnel in the general medical and patient environment; it also contains certain requirements for reliable
operation to ensure safety.
The General Standard has associated Collateral Standards and Particular Standards. The Collateral
Standards include requirements for specific technologies and/or hazards and apply to all applicable equipment,
such as medical electrical systems, EMC, radiation protection in diagnostic X-ray equipment, software, etc.
The Particular Standards apply to specific equipment types, such as medical electron accelerators, high
frequency surgical equipment, hospital beds, etc.
NOTE Definitions of Collateral Standard and Particular Standard can be found in IEC 60601-1:1988, 1.5 and A.2,
respectively.
To facilitate the use of this International Standard, the following drafting conventions have been applied.
This International Standard uses the same main clause titles and numbering as the General Standard, for
ease of cross-referencing of the requirements. The changes to the text of the General Standard, as
supplemented by the Collateral Standards, are specified by the use of the following words.
“Replacement” means that the indicated clause or subclause of the General Standard is replaced
completely by the text of this International Standard.
“Addition” means that the relevant text of this Particular Standard is a new element (e.g. subclause, list
item, note, table, figure) additional to the General Standard.
“Amendment” means that an existing element of the General Standard is partially modified by deletion
and/or addition as indicated by the text of this Particular Standard.
To avoid confusion with any amendments to the General Standard itself, a particular numbering has been
employed for elements added by this International Standard: subclauses, tables and figures are numbered
starting from 101; additional list items are lettered aa), bb), etc. and additional annexes are lettered AA, BB,
etc.
In this International Standard, the following print types are used:
requirements, compliance with which can be verified, and definitions: roman type;
notes and examples: smaller roman type;
description of type of document change and test methods: italic type;

Particular requirements
1 Scope
IEC 60601-1:1988, Clause 1, applies except as follows:
Amendments (add at end of 1.1):
1.1
This International Standard specifies requirements for the safety and essential performance of transportable
liquid oxygen systems which are used as a supply source for oxygen therapy. These devices usually consist
of a portable unit to be carried by or with the patient whilst in use and the vessel used to refill the portable
unit. These devices are mostly used in home care applications and in health care facilities/institutions. These
devices are often used without professional supervision.
Liquid oxygen vessels used as a supply source for oxygen pipeline systems are excluded from this
International Standard.
The requirements of this International Standard which replace or modify the requirements of
IEC 60601-1:1998 and its Amendments 1 (1991) and 2 (1995) are intended to take precedence over the
corresponding general requirements.
1.4
Addition:
NOTE Planning and design of products complying with this Internatinal Standard can have environmental impact
during the product life cycle. Environmental aspects are addressed in Annex BB. Additional aspects of environmental
impact are addressed in ISO 14971.
