5.4.3 Chinniki scho vplivayut on naslіdki urazhennya elektrostrumom

Naslіdki urazhennya Helsinki Human elektrichnim Strum stale od fіzichnih parametrіv elektrichnogo cola i deyakih fіzіologіchnih chinnikіv, SSMSC pritamannі zhivim organіzmam.

Naslіdki urazhennya stale od support shkіri that support vnutrіshnіh organіv. Tse zmіnna value scho Got nelіnіynu zalezhnіst od will shkіri, navkolishnogo seredovischa, parametrіv elektrichnoї MEREZHI that іn ..

Tovschina horny ball on rіznih dіlyankah rіzna (0,02-0,2mm). Opіr epіdermіsu in 1000 razіv bіlshy for opіr dermis. When i suhіy neposhkodzhenіy shkіrі opіr tіla Helsinki Human kolivaєtsya in wide furrows (3,000 to 100,000 ohms), Yakscho zіskobliti horns ball opіr bude to 1000-5000 ohms.

Elektroprovіdnіst Strum zbіlshuєtsya at zvolozhennі i zabrudnennі shkіri, Especially timey rechovinami, scho good conductive Strum.

Opіr shkіri neodnakovy on rіznih dіlyankah tіla, to naslіdki urazhennya mozhut zalezhati od Georeferencing contact elektroda s tіlom Helsinki Human. Naymenshy opіr Got shkіra oblichchya, shiї, tilnoї kistі side of the hand, pid pahovoї depression. On tili Helsinki Human Je tsіly number tochok, opіr shkіri on yakih uniquely Mensch nіzh on susіdnіh dіlyankah scho spіvpadaє s topografієyu golkovkolyuvannya, yak pіddaєtsya no explanation.

Otzhe, opіr tіla Helsinki Human - tse zmіnna value scho Mauger kolivatisya in wide furrows. However, when she doborі zahisnih tehnіchnih zasobіv Zahist od urazhennya elektrichnim Struma for opіr tіla Helsinki Human priymayut 1000 ohms.

Before fіzichnih parametrіv elektrichnogo Strum, scho Yea virіshalnimi at urazhennі organіzmu nalezhat:

• Strum force;
• napruga;
• rіd Struma;
• frequency.

Stupіn negativnoї dії Strum on organіzm Helsinki Human zbіlshuєtsya at zbіlshennі Sealy Strum.

Rozrіznyayut three stages dії Sealy Strum.

• vіdchutny 0.1 mA at zmіnnomu i 5-7 mA at postіynomu strumі;
• nevіdpuskayuchy zmіnny 10-20 mA, 50-80 mA postіyny;
• fіbrilyatsіy tions Strum 100 mA zmіnny, 3000 mA postіyny.

Threshold vіdchutny Strum not Mauger viklikati urazhennya in Helsinki Human i tsomu vipadku vіn vvazhaєtsya bezpechnim.

Yakscho force Strum bіlsha vіdchutnogo threshold vinikayut the Court m'yazіv i nepriєmnі vіdchuttya. Bіl staє nesterpnim, sudomne skorochennya m'yazіv staє such digit, scho Person of Mauger yogo not overcome, not Mauger rozіmknuti hands i samostіyno pripiniti contact Zi strumoveduchoyu Chastain. Taqiy Strum Je nebezpechnim for Helsinki Human, Yakscho vіn not viklikaє raptovogo її urazhennya, but when trivalomu kontaktі yogo Bude zrostati values ​​for rakhunok znizhennya support tіla Helsinki Human scho Mauger prizvesti navіt to smertі.

Character dії Strum on organіzm Helsinki Human deposits od magnitude naprugi.

When zbіlshennі naprugi, opіr tіla Helsinki Human zmenshuєtsya have dozens razіv. Pіdvischennya naprugi generally produces to penetration of the horny ball shkіri.

Opіr tіla Helsinki Human postіynomu Strum bіlshy nіzh zmіnnomu. Experiental vstanovleno, scho i 42V 120V postіynogo zmіnnogo Strum viklikayut odnakovі urazhennya.

Naslіdki elektrotravmatizmu uniquely stale od frequency now Strum. Naynebezpechnіshim vіdnosno elektroudarіv Je zmіnny Strum 50Hz and Zi zbіlshennyam frequency now nebezpeka urazhennya zmenshuєtsya. Zmenshennya dії pochinaєtsya s 1000Hz frequency now.

Visokochastotnі Stroomi, scho perevischuyut sotnі kHz, yak usually not prizvodyat to elektrichnih udarіv. Tsі osoblivostі visokochastotnih strumіv vikoristovuyutsya in meditsinі. UHF, VHF, ZVCH widely zastosovuyutsya s lіkuvalnoyu metoyu.

Naslіdki urazhennya organіzmu viznachaє takozh hour prohodzhennya Strum through tіlo Helsinki Human, bo s hour rіzko padaє opіr tіla. Chim dovshe bude dіyati Strum, team bіlsha ymovіrnіst vazhkogo urazhennya abo fatal.

Vstanovleno scho chutlivіst insertions to Strum neodnakova in rіznі Fazi yogo dіyalnostі. Cutaneous cycle sertsevoї dіyalnostі skladaєtsya s dvoh perіodіv one nazivaєtsya dіastoloyu (if shlunochki insertions perebuvayut in rozslablenomu stanі zapovnyuyutsya krov'yu i) Other - systole, if Serce, skorochuyuchis, vishtovhuє shelter in arterіalnі sudini.

Іmovіrnіst viniknennya fіbrilyatsії insertions, tobto nebezpeki deadly urazhennya Strum, deposits of od, s yakoyu fazoyu Sertsevy cycle spіvpadaє hour prohodzhennya Strum through the heart with very. Granichno admissibility hour dії vvazhayut 0.1s.
