12、l CLINICAL THERMOMETERS, either already available or that will come available in the future. The purpose of a CLINICAL THERMOMETER is to assess the true temperature of a REFERENCE BODY SITE. The temperature of the PATIENTS body is an important vital sign in assessing overall health, typically in com

13、bination with blood pressure and pulse rate. Determining whether a PATIENT is afebrile, febrile or hypothermic is an important purpose of a CLINICAL THERMOMETER, since being febrile suggests that the PATIENT is ill. There are different temperatures at each REFERENCE BODY SITE according to the balanc

14、e between the production, transfer, and loss of heat2. CLINICAL ACCURACY of a CLINICAL THERMOMETER is VERIFIED by comparing its OUTPUT TEMPERATURE with that of a REFERENCE THERMOMETER, which has a specified uncertainty for measuring true temperature. For an equilibrium CLINICAL THERMOMETER, the CLIN

15、ICAL ACCURACY can be sufficiently determined under laboratory conditions that create an equilibrium state between the two thermometers. For a CLINICAL THERMOMETER that operates in the ADJUSTED MODE, laboratory VERIFICATION alone is not sufficient because the adjustment algorithm for deriving the OUT

16、PUT TEMPERATURE includes the characteristics of the PATIENT and the environment3. Therefore, the CLINICAL ACCURACY of a CLINICAL THERMOMETER that operates in the ADJUSTED MODE has to be VALIDATED clinically, using statistical methods of comparing its OUTPUT TEMPERATURE with that of a REFERENCE CLINI

17、CAL THERMOMETER which has a specified CLINICAL ACCURACY in representing a particular REFERENCE BODY SITE temperature. For a CLINICAL THERMOMETER that operates in the ADJUSTED MODE, the LABORATORY ACCURACY is VERIFIED in a DIRECT MODE and the CLINICAL ACCURACY is VALIDATED in the ADJUSTED MODE (OPERA

18、TING MODE) with a sufficiently large group of human subjects. The intention of this document is to specify the requirements and the test PROCEDURES for the VERIFICATION of the LABORATORY ACCURACY for all types of electrical CLINICAL THERMOMETERS as well as for the VALIDATION of the CLINICAL ACCURACY

19、 of a CLINICAL THERMOMETER that operates in the ADJUSTED MODE. This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

29、he BASIC SAFETY and ESSENTIAL PERFORMANCE of a CLINICAL THERMOMETER in combination with its ACCESSORIES, hereafter referred to as ME EQUIPMENT. This document specifies the general and technical requirements for electrical CLINICAL THERMOMETERS. This document applies to all electrical CLINICAL THERMO

30、METERS that are used for measuring the BODY TEMPERATURE of PATIENTS. CLINICAL THERMOMETERS can be equipped with interfaces to accommodate secondary indicators, printing equipment, and other auxiliary equipment to create ME SYSTEMS. This document does not apply to auxiliary equipment. ME EQUIPMENT th

31、at measures a BODY TEMPERATURE is inside the scope of this document. This document does not specify the requirements for screening thermographs intended to be used for the individual noninvasive human febrile temperature screening of groups of individual humans under indoor environmental conditions,

32、 which are given in IEC 806012594. 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 SY

33、STEMS, 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 IEC 606011:2005+A1:2012, 7.2.13 and 8.4.1. NOTE Additional information can be found in IEC 6

34、06011:2005+A1:2012, 4.2. 201.1.2 Object Replacement: The object of this particular document is to establish particular BASIC SAFETY and ESSENTIAL PERFORMANCE requirements for a CLINICAL THERMOMETER, as defined in 201.3.206, and its ACCESSORIES. NOTE ACCESSORIES are included because the combination o

35、f the CLINICAL THERMOMETER and the ACCESSORIES needs to be safe and effective. ACCESSORIES can have a significant impact on the BASIC SAFETY and ESSENTIAL PERFORMANCE of a CLINICAL THERMOMETER.

All other published collateral standards in the IEC 606011 series apply as published. 201.1.4 Particular standards Replacement: In the IEC 60601 series, particular standards may modify, replace or delete requirements containe

38、d in the general standard as appropriate for the particular ME EQUIPMENT under consideration, and may add other BASIC SAFETY and ESSENTIAL PERFORMANCE requirements. A requirement of a document takes priority over IEC 606011 and its collateral standards. For brevity, IEC 606011:2005+A1:2012 is referr

39、ed to in this document as the general standard. Collateral standards are referred to by their document number. The numbering of sections, clauses and subclauses of this document corresponds to that of the general standard with the prefix “201” (e.g. 201.1 in this document addresses the content of Cl

40、ause 1 of the general standard) or applicable collateral standard with the prefix “20x” where x is the final digit(s) of the collateral standard document number (e.g. 202.4 in this document addresses the content of Clause 4 of the 6060112 collateral standard, 203.4 in this document addresses the con

41、tent of Clause 4 of the 6060113 collateral standard, 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 IEC 606011 or applicable collateral standard is replaced completely by the text of this

42、 particular document. “Addition” means that the text of this document is additional to the requirements of the IEC 606011 or applicable collateral standard. “Amendment” means that the clause or subclause of the IEC 606011 or applicable collateral standard is amended as indicated by the text of this

43、document. Subclauses or figures which are additional to those of the general standard are numbered starting from 201.101, Additional annexes are lettered AA, BB, etc., and additional items aa), bb), etc. Subclauses or figures which are additional to those of a collateral standard are numbered starti

44、ng from 20x, where “x” is the number of the collateral standard, e.g. 202 for IEC 6060112, 203 for IEC 6060113, etc. The term “this document” is used to make reference to the IEC 606011:2005+A1:2012, any applicable collateral standards and this document taken together. Where there is no correspondin

45、g section, clause or subclause in this document, the section, clause or subclause of the IEC 606011 or applicable collateral standard, although possibly not relevant, applies without modification; where it is intended that any part of the IEC 606011 or applicable collateral standard, although possib
