DIN EN ISO 18777:2009-07 EN ISO 18777:2009 (E) 4Introduction 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
34、to provide additional insight into the committees 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 St
35、andard 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 an
36、d 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
37、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 Collate
38、ral 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 Stan
39、dard, 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 compl
40、etely 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
41、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 st
42、arting 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
43、type; description of type of document change and test methods: italic type; terms defined in the General Standard IEC 60601-1:1988, Clause 2, or in this Particular Standard: bold type. Throughout this International Standard, text for which a rationale is provided in Annex AA is indicated by an aster
44、isk (*). DIN EN ISO 18777:2009-07 EN ISO 18777:2009 (E) 51 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 use
45、d 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 devi
46、ces 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 Amendment
47、s 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
48、BB. Additional aspects of environmental impact are addressed in ISO 14971. 2 Normative references The following referenced documents are indispensable for the application of this document.
