Appareils électromédicaux - Partie 2-71: Exigences particulières pour la sécurité de base et les performances essentielles des appareils d’imagerie spectroscopique proche infrarouge (NIRS)

IEC 80601-2-71:2015 s'applique à la sécurité de base et aux performances essentielles des appareils NIRS fonctionnelle destinés à être utilisés seuls, ou en tant que partie d'un système EM, pour produire des caractéristiques de sortie d'appareils NIRS fonctionnelle, à des fins de diagnostic d'appoint. Ces appareils sont désignés ci-après appareils EM.

Medicinska električna oprema - 2-71. del: Posebne zahteve za osnovno varnost in bistvene lastnosti funkcionalne opreme spektrometra v bližnjem infrardečem spektru (IEC 80601-2-71:2015)

Standard EN-IEC 80601-2-71 se uporablja za OSNOVNO VARNOST in BISTVENE LASTNOSTI FUNKCIONALNE OPREME SPEKTOMETRA V BLIŽNJEM INFRARDEČEM SPEKTRU (NIRS), namenjene za samostojno uporabo ali kot del SISTEMA ME, za proizvodnjo izpisa FUNKCIONALNE OPREME NIRS za dodatne diagnostične namene, v nadaljevanju imenovane OPREMA ME. Področje uporabe tega zadevnega standarda ne vključuje: a) dela OPREME ME, ki meri nasičenost hemoglobina s kisikom v mikro-žilah (kapilarah, arteriolah in venulah), če je prisotna; b) opreme tkivnega oksimetra v bližnjem infrardečem spektru (NIRS), ki ni namenjena za pridobivanje izpisa FUNKCIONALNE OPREME NIRS; c) opreme pulznega oksimetra, ki ni namenjena za pridobivanje izpisa FUNKCIONALNE OPREME NIRS. Zahteve za opremo pulznega oksimetra so določene v standardu ISO 80601-2-61; d) frekvenčne in časovne opreme za funkcionalno spektroskopijo v bližnjem infrardečem spektru, ki lahko zahtevajo drugačne preskusne postopke, kot so opredeljeni tukaj; e) FUNKCIONALNE OPREME SPEKTOMETRA V BLIŽNJEM INFRARDEČEM SPEKTRU, ki meri spremembe v koncentraciji drugih kromoforov, ki niso oksi- in deoksihemoglobin, ki lahko zahtevajo drugačne preskusne postopke, kot so opredeljeni tukaj.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
