Nibihe bice bine byimashini ya EKG?

EKG, cyangwa Electrocardiogram, ni imashini ikoreshwa mugukurikirana no gusuzuma ibibazo byumutima bishobora kuba kumurwayi wubuvuzi.Electrode ntoya ishyirwa mugituza, impande, cyangwa ikibuno.Ibikorwa byamashanyarazi yumutima bizandikwa kumpapuro zidasanzwe zishushanyije kubisubizo byanyuma.Hano hari ibintu bine byibanze kumashini ya EKG.

Amashanyarazi

Electrode igizwe nubwoko bubiri, bipolar na unipolar.Bipolar electrode irashobora gushirwa kumaboko yombi no kumaguru kugirango bapime itandukaniro rya voltage hagati yombi.Electrode ishyirwa kumaguru yibumoso hamwe nintoki zombi.Ku rundi ruhande, electrode ya Unipolar, ipima itandukaniro rya voltage cyangwa ikimenyetso cyamashanyarazi hagati ya electrode idasanzwe hamwe nubuso bwumubiri nyirizina mugihe ushyizwe kumaboko yombi namaguru.Ikoreshwa rya electrode ni electrode isanzwe yumutima umutima abaganga bakoresha kugirango bagereranye ibipimo.Birashobora kandi kwizirika ku gituza no kureba uko umutima uhinduka.

Amplifiers

Amplifier asoma ibimenyetso byamashanyarazi mumubiri akabitegura kubikoresho bisohoka.Iyo ikimenyetso cya electrode kigeze kuri amplifier cyoherejwe bwa mbere muri buffer, igice cya mbere cya amplifier.Iyo igeze kuri buffer, ibimenyetso birahagarara hanyuma bigahindurwa.Nyuma yibi, amplifier itandukanye ishimangira ibimenyetso 100 kugirango usome neza ibipimo byibimenyetso byamashanyarazi.

Guhuza insinga

Intsinga ihuza ni igice cyoroshye cya EKG gifite uruhare rugaragara mumikorere ya mashini.Intsinga ihuza itanga ibimenyetso byasomwe muri electrode hanyuma ikohereza kuri amplifier.Izi nsinga zihuza na electrode;ikimenyetso cyoherejwe binyuze muri bo kandi gihujwe na amplifier.

Ibisohoka

Ibisohoka nigikoresho kuri EKG aho ibikorwa byamashanyarazi byumubiri bitunganyirizwa hanyuma bikandikwa kumpapuro.Imashini nyinshi za EKG zikoresha icyo bita impapuro zandika.Nyuma yo gusohoka yandika igikoresho, umuganga yakira-kopi yibipimo.Imashini zimwe za EKG zanditse ibipimo kuri mudasobwa aho kuba impapuro zandika.Ubundi bwoko bwamajwi ni oscilloscopes, hamwe na magnetiki kaseti.Ibipimo bizabanza kwandikwa mubigereranyo hanyuma bihindurwe mubisomwa.
