32、CT BLOOD PRESSURE MONITORING EQUIPMENT. Hence, changes need to be made to include these unique requirements. This particular standard takes into account Collateral Standard 60601-1-2:(1993) Electromagnetic compatibility and Collateral Standard 60601-1-4:(1996) Medical electrical equipment incorporat

33、ing programmable electrical systems. A section on ALARMS has been included because ALARMS are necessary for MONITORING EQUIPMENT.

34、ure monitoring equipment SECTION ONE GENERAL The clauses and subclauses of this section of the General Standard apply except as follows: 1 Scope and object This clause of the General Standard applies except as follows: *1.1 Scope Addition: This Particular Standard applies to INVASIVE BLOOD PRESSURE

35、MONITORING and measuring EQUIPMENT as defined in 2.101, hereinafter referred to as EQUIPMENT. This Particular Standard does not apply to catheter tubing, catheter needles, Luer locks, taps and tap tables. This Particular Standard also does not apply to NON-INVASIVE BLOOD PRESSURE MONITORING EQUIPMEN

36、T. 1.2 Object Replacement: The object of this Particular Standard is to establish particular requirements for the safety, including the essential performance of EQUIPMENT, as defined in 2.101. 1.3 Particular Standards Addition: This Particular Standard refers to IEC 60601-1:1988, Medical electrical

37、equipment Part 1: General requirements for safety as amended by its amendment 1 (1991) and its amendment 2 (1995). The General Standard takes into account IEC 60601-1-2:1993, Medical electrical equipment Part 1: General requirements for safety 2. Collateral Standard: Electromagnetic compatibility Re

38、quirements and tests and IEC 60601-1-4:1996, Medical electrical equipment Part 1: Collateral Standard: Programmable electrical medical systems. For brevity, IEC 60601 is referred to in this Particular Standard either as the “General Standard” or as the “General Requirement(s)”. Page6 EN60601234:2000

39、 BSI 04-2001 The numbering of sections, clauses or subclauses of this Particular Standard corresponds to that of the General Standard. The changes to the text of the General Standard are specified by the use of the following words: “Replacement” means that the clause or subclause of the General Stan

40、dard is replaced completely by the text of this Particular Standard. “Addition” means that the clause or subclause of this Particular Standard is additional to the requirements of the General Standard. “Amendment” means that the clause or subclause of the General Standard is amended as indicated by

41、the text of this Particular Standard. Subclauses or figures which are additional to those of the General Standard are numbered starting from 101, additional annexes are lettered AA, BB, etc, and additional items aa), bb), etc. The term “this Standard” is used to make reference to the General Standar

42、d and this Particular Standard taken together. An asterisk (*) notes clauses for which there is rationale comment in annex AA or annex BB. It is considered that a knowledge of the reasons for these requirements will facilitate the proper application of the standard and be of use in any revision that

43、 may be necessitated by changes in clinical practice or as a result of developments in technology. Where there is no corresponding section, clause or subclause in this Particular Standard, the section, clause or subclause of the General Standard, although possibly not relevant, applies without modif

44、ication; 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 priority over those of the General Standard and of the Collateral

45、Standards mentioned above. 2 Terminology and definitions This clause of the General Standard applies except as follows: 2.1.5 APPLIED PART Replacement: The TRANSDUCER, including any fluid-filled system.
