Introduction of YY 9706.230-2023

Medical electrical equipment -Part 2-30: Particular requirements for the basic safety and essential performance of automated non-invasive sphygmomanometers 201.1 Scope, object and related standards Clause 1 of GB 9706.1-2020 applies, except as follows: 201.1.1 Scope Replacement: This document specifies requirements for the basic safety and essential performance for automated non-invasive sphygmomanometer and its accessories, including the requirements for the accuracy of a determination. This document applies to the automated non-invasive sphygmomanometers, hereafter referred to as ME equipment, which, by means of an inflatable cuff, are used for non-continuous indirect estimation of the blood pressure without arterial puncture. Note 1: Equipment that performs indirect determination of the blood pressure without arterial puncture does not directly measure the blood pressure. It only estimates the blood pressure. Note 2: This document covers automatic electrically-powered ME equipment used for the intermittent, indirect estimation of the blood pressure without arterial puncture, including blood pressure monitors for the home healthcare environment. This document does not apply to equipment for determination of the blood pressure with an electrically-powered pressure transducer and/or displays used in conjunction with a stethoscope or other manual methods (non-automated non-invasive sphygmomanometers). Requirements for such equipment are specified in document ISO 81060-1. Note 3: If a clause or subclause is specifically intended to be applicable to ME equipment only, or to ME systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME equipment and to ME systems, as relevant.   Hazards inherent in the intended physiological function of ME equipment or ME systems within the scope of this document are not covered by specific requirements in this document except in 201.11 and 201.105.3.3, as well as 7.2.13 and 8.4.1 of GB 9706.1-2020. 201.1.2 Object Replacement: The object of this particular standard is to establish particular basic safety and essential performance requirements for an automated non-invasive sphygmomanometer as defined in 201.3.201. 201.1.3 Collateral standards Addition: This particular standard refers to those applicable collateral standards that are listed in Clause 2 of the general standard and 201.2 of this particular standard. YY 9706.102, YY/T 9706.106, YY/T 9706.110, YY 9706.111 and YY 9706.112 apply as modified in Clauses 202, 206, 210, 211 and 212 respectively. GB 9706.103-2020 does not apply. All other published collateral standards in the 9706 series apply as published. 201.1.4 Particular standards Replacement: In the 9706 series, particular standards may modify, replace or delete requirements contained in the general standard and collateral standards as appropriate for the particular ME equipment under consideration, and may add other basic safety and essential performance requirements. A requirement of a particular standard takes priority over the general standard. For brevity, GB 9706.1-2020 is referred to in this particular standard as the general standard. Collateral standards are referred to by their document number.   The numbering of clauses and subclauses of this particular standard corresponds to that of the general standard with the prefix "201" (e.g. 201.1 in this document addresses the content of Clause 1 of the general standard) or applicable collateral standard with the prefix "20×", where × is the final digit(s) of the collateral standard document number (e.g. 202.4 in this particular standard addresses the content of Clause 4 of the international standard IEC 60601-1-2 corresponding to the collateral standard YY 9706.102, 203.4 in this particular standard addresses the content of Clause 4 of the international standard IEC 60601-1-3 corresponding to the collateral standard GB 9706.103, etc.). 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 standard or applicable collateral 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 or applicable collateral standard. "Amendment" means that the clause or subclause of the general standard or applicable collateral standard is amended as indicated by the text of this particular standard. Subclauses, figures or tables which are additional to those of the general standard are numbered starting from 201.101. However, due to the fact that definitions in the general standard are numbered 3.1 through 3.147, additional definitions in this document are numbered beginning from 201.3.201. Additional annexes are lettered AA, BB, etc., and additional items aa), bb), etc. Subclauses, figures or tables which are additional to those of a collateral standard are numbered starting from "20×", where "×" is the final digit(s) of the collateral standard document number, e.g. 202 for the international standard IEC 60601-1-2 corresponding to YY 9706.102, 203 for the international standard IEC 60601-1-3 corresponding to GB 9706.103, etc. The term "this document" is used to make reference to the general standard, any applicable collateral standards and this particular standard taken together. Where there is no corresponding clause or subclause in this particular standard, the clause or subclause of the general standard or applicable collateral standard, although possibly not relevant, applies without modification; where it is intended that any part of the general standard or applicable collateral standard, although possibly relevant, is not to be applied, a statement to that effect is given in this particular standard.
