Ukusetshenziswa kweFilimu Capacitor
ku-Cardiac Defibrillator
I-Defibrillation yiyona ndlela kuphela ephumelelayo yokwelapha ukufa okuzumayo kwenhliziyo
I-cardiac defibrillator okwamanje isetshenziswa kabanzi imishini yokuhlenga emitholampilo.Isebenzisa i-pulsed current ukuze isebenze enhliziyweni, isebenzise ukwelashwa kokushaqeka ngogesi, iqede i-arrhythmia, futhi ibuyisele inhliziyo kusigqi se-sinus..
Umgomo wayo wokusebenza kakhulu wamukela indlela yokukhipha i-RLC, njengoba kukhonjisiwe emfanekisweni:
| Idatha ejwayelekile | |
| Amandla | 100~500J |
| Amandla kagesi | 2000 ~ 5000VDC |
| Amandla | 32 ~ 200 UF |
| Ukukhulula umthwalo | 20Ω/50Ω/100Ω |
| Ubuningi be-pulse current | 100 ~ 1kA |
Okokuqala shaja i-capacitor yokugcina amandla C ukuze wenze i-capacitor ithole inani elithile lamandla.Ngesikhathi sokwelashwa kwe-defibrillation, i-C, inductance L kanye nomzimba womuntu (umthwalo) kuxhunywe ochungechungeni ukwenza ukwelashwa kokushaqeka ngogesi enhliziyweni yomuntu.
●Amandla agciniwe
Amandla kagesi ashajwa kudivayisi yokugcina amandla ngaphambi kokushaqeka kwe-defibrillation.Ubudlelwano phakathi kwamandla agcinwe ku-capacitor kanye ne-voltage ye-capacitor:
E=½ cu²
Ngohlelo lokusebenza ku-defibrillator, i-CRE film capacitor inomklamo okhethekile owenziwe ngokwezifiso, onezinzuzo eziphezulu zokusebenza:
Uma kuqhathaniswa nempilo yesevisi yezikhathi ezingu-10,000 emakethe, umklamo okhethekile wesakhiwo sefilimu wenza izikhathi zempilo yokushaja nokukhipha izikhathi ezingaphezu kwezingu-30,000.
Ngokucabangela ukusetshenziswa kwemvelo engaqinisekile futhi enokhahlo njengangaphandle, yamukela idizayini ekhethekile yokulwa nomswakama kanye nokumelana nokushisa okuphezulu, enokwethenjelwa okuphezulu.
Ikakhulukazi ukwakhiwa kwevolumu encane ye-othomathikhi ye-othomathikhi yangaphandle (AED) (njengezidingo eziphathwa ngesandla), kusetshenziswa izinto ezisetshenziswa amandla aphezulu, ivolumu nesisindo kuncane ngo-50% kunomklamo ojwayelekile.
