36、TRODUCTION The minimum safety requirements specified in this particular standard are considered to provide for a practical degree of safety in the operation of ME EQUIPMENT for human febrile temperature screening. This document describes ME EQUIPMENT that uses infrared technology to detect naturally
37、 emitted heat at the skin surface of the FACE. Such ME EQUIPMENT can be useful at ports-of-entry or ports-of-exit and the entrances to buildings under indoor environmental conditions to separate febrile from afebrile individuals to help prevent the spread of communicable diseases. Care can be needed
38、 when evaluating individuals under changing environmental conditions, but the inner canthus of the eye has been demonstrated to be a robust measurement site and is supplied by the internal carotid artery. 401)A body core temperature of 38 C or above was used as the criterion to restrict traveling du
39、ring the SARS (severe acute respiratory syndrome) epidemic (April 2003). 73 The US Center for Disease Control advises that SARS typically begins with a temperature above 38 C, which is 1 C higher than normal human body core temperature which averages around 37 C. 29 It is hard to give an accurate as
40、sessment of how many people were checked by infrared temperature measurements in China during the SARS epidemic. There is official Chinese government data indicating that during a two-month period in the spring of 2003, 30 million travelers were screened in China. From this cohort, 9 292 travelers w
41、ith elevated temperature were detected and 38 were suspected of being SARS carriers. SARS was diagnosed in 21 of these cases. All elevated temperatures were confirmed using traditional clinical temperature measurements of body temperature. Although it is hard to determine the human bodys core temper
42、ature accurately by infrared measurement of SKIN TEMPERATURE, it is a potential method for screening for elevated temperature values. 36 73 75 This particular standard amends and supplements IEC 60601-1 (third edition, 2005): Medical electrical equipment Part 1: General requirements for safety and e
43、ssential performance, hereinafter referred to as the General Standard (see 1.4). The requirements are followed by specifications for the relevant tests. A “General guidance and rationale“ section giving some explanatory notes, where appropriate, about the more important requirements is included in a
44、nnex AA. It is considered that knowledge of the reasons for these requirements will not only facilitate the proper application of the standard 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
45、 does not form part of the requirements of this standard. 1)Figures in square brackets refer to the Bibliography.

An elevated SKIN TEMPERATURE needs to be followed up by a subsequent temperature measurement using a clinical thermometer (see IEC 80601-2-56).
