39、or 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 emitted heat at the skin surface of the FACE. Such ME EQUIPMENT can be useful at ports-of-entry or ports-of

Care can be needed when evaluating individuals under changing environmental conditions, but the inner canthus of the eye has b

41、een 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 during the SARS (severe acute respiratory syndrome) epidemic (April 2003). 73 The US Center for Disease Contro

42、l 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 assessment of how many people were checked by infrared temperature measurements in China during the SARS epide

43、mic. 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 with elevated temperature were detected and 38 were suspected of being SARS carriers. SARS was diagnosed in 2

44、1 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 temperature accurately by infrared measurement of SKIN TEMPERATURE, it is a potential method for screening for ele

45、vated 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 essential performance, hereinafter referred to as the General Standard (see 1.4). The requirements are follow

46、ed 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 annex AA. It is considered that knowledge of the reasons for these requirements will not only facilitate the

47、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 does not form part of the requirements of this standard. 1)Figures in square brackets refer to the Bibliogr
