O BSI 8 November 2001 Page 4 EN 60601-2-49:2001 INTRODUCTION This Particular
26、 Standard concerns the safety of multifunction patient monitoring equipment. It amends and supplements IEC 60601-1 (second edition 1988), hereinafter referred to as the General Standard. The requirements of this Particular Standard take priority over those of the General Standard, entitled “Medical
27、electrical equipment - Part I: General requirements for safety”. A “General guidance and rationale” for the requirements of this Particular Standard is included in annex AA. It is considered that knowledge of the reasons for these requirements will not only facilitate the proper application of the s
28、tandard but will, in due course, expedite any revision necessitated by changes in clinical practice or as a result of developments in technology. However, this annex does not form part of the requirements of this Standard. An asterisk (*) by a clause or subclause number indicates that some explanato
29、ry notes are given in Annex A of this Particular Standard. At the time of the publication of this Particular Standard, work was in progress to create a joint ISO/IEC collateral standard addressing “General requirements and guidelines for the application of alarms in medial electrical equipment”. It
30、is intended to harmonize this standard with the above-mentioned collateral standard after its publication.

31、RAL This section of the General Standard applies except as follows: 1 Scope and object *1.1 Scope This Particular Standard applies to the safety requirements of MULTIFUNCTION PATIENT MONITORING EQUIPMENT as defined in subclause 2.2.101. The scope of this standard is restricted to EQUIPMENT having ei
32、ther more than one APPLIED PART or more than one SINGLE FUNCTION, intended for connection to a single PATIENT. This standard does not specify requirements for individual monitoring functions. 1.2 Object The object of this Particular Standard is to specify requirements for the safety of MULTIFUNCTION
33、 PATIENT MONITORING EQUIPMENT. 1.3 Particular Standards Addition: This Particular Standard refers to IEC 60601-1 (1988): Medical electrical equipment - Part 7: General requirements for safety as amended by its amendment 1 (1991) and amendment 2 (1 995). For brevity, Part 1 is referred to in this Par
34、ticular Standard either as the “General Standard” or as the “Gen era I Re q u i re m e n t ( s )” . The numbering of sections, clauses and subclauses of this Particular Standard corresponds to that of the General Standard. Changes to the text of the General Standard are specified by the use of the f
35、ollowing words: “Replacement” means that the clause or subclause of the General Standard is replaced completely by the text of this Particular Standard. “Addition” means that the text of this Particular Standard is additional to the requirements of the General Standard. “Amendment” means that the cl
36、ause or subclause of the General Standard is amended as indicated by the text of this Particular Standard. O BSI 8 November 2001 Page 6 EN 60601-2-49:2001 Subclauses or figures which are additional to those of the General Standard are numbered starting from 101, additional annexes are lettered AA, 6
37、6, etc., and additional items aa), bb), etc. The term “this Standard” is used to make reference to the General Standard and this Particular Standard taken together. Where there is no corresponding section, clause or subclause in this Particular Standard, the section, clause or subclause of the Gener
38、al Standard, although possibly not relevant, applies without modification; where it is intended that any part of the General Standard, although possibly relevant, is not to be applied, a statement to that effect is given in this Particular Standard. The requirements of this Particular Standard take
39、priority over those of the General Standard and Collateral Standard mentioned above. 1.5 Collateral standards Addition: IEC 60601-1-2: 1993, Medical electrical equipment - Patt 1: General requirements for safety - 2.
