Ukusetyenziswa kweFilimu Capacitor
kwi-Cardiac Defibrillator
I-Defibrillation kuphela kwendlela esebenzayo yokunyanga ukufa kwentliziyo ngokukhawuleza
I-defibrillator ye-cardiac ngoku isetyenziswa ngokubanzi izixhobo zokuhlangula zeklinikhi.Isebenzisa i-pulsed current ukuze isebenze entliziyweni, iphumeze unyango lokothuka kombane, ukuphelisa i-arrhythmia, kunye nokubuyisela intliziyo kwisigqi se-sinus..
Umgaqo wayo wokusebenza wamkela indlela yokukhupha i-RLC, njengoko kubonisiwe kumfanekiso:
| Idatha eqhelekileyo | |
| Amandla | 100~500J |
| I-Voltage | 2000~5000VDC |
| Ukubanakho | 32-200UF |
| Ukukhupha umthwalo | 20Ω/50Ω/100Ω |
| Ubuninzi be-pulse yangoku | 100~1kA |
Okokuqala ukuhlawula i-capacitor yokugcina amandla C ukwenza i-capacitor ifumane umlinganiselo othile wamandla.Ngethuba lokunyangwa kwe-defibrillation, i-C, i-inductance L kunye nomzimba womntu (umthwalo) uxhunywe kwichungechunge ukwenza unyango lokutshatyalaliswa kombane entliziyweni yomntu.
●Amandla agciniweyo
Amandla ombane afakwe kwisixhobo sogcino lwamandla phambi komothuko we-defibrillation.Ubudlelwane phakathi kwamandla agcinwe kwi-capacitor kunye nombane we-capacitor:
E=½ cu²
Ukusetyenziswa kwi-defibrillator, i-CRE film capacitor inoyilo olukhethekileyo olulungiselelwe, olunenzuzo ephezulu yokusebenza:
Xa kuthelekiswa ne-10,000 yamaxesha obomi benkonzo kwimarike, uyilo olukhethekileyo lwesakhiwo sefilimu lwenza ukutshaja kunye nokukhupha amaxesha obomi ngaphezu kwamaxesha angama-30,000.
Uthathela ingqalelo usetyenziso lwemekobume engaqinisekanga kunye nerhabaxa efana nangaphandle, ithatha i-anti-humidity ekhethekileyo kunye noyilo lokumelana nobushushu obuphezulu, obunokuthembeka okuphezulu.
Ngokukodwa kwidizayini yomthamo omncinci we-defibrillator yangaphandle (i-AED) (njengeemfuno eziphathwayo), usebenzisa izinto ezixinzelelekileyo zamandla, umthamo kunye nobunzima yi-50% encinci kunoyilo oluqhelekileyo.
