Ukusetshenziswa kwe-Film Capacitor
ku-Cardiac Defibrillator
Ukuqeda i-defibrillation kuyindlela ephumelelayo yokwelapha ukufa kwenhliziyo okuzumayo
I-cardiac defibrillator okwamanje isetshenziswa kabanzi imishini yokutakula emtholampilo. Isebenzisa i-pulsed current ukusebenza enhliziyweni, ukusebenzisa ukwelashwa ngogesi, ukuqeda i-arrhythmia, nokubuyisela inhliziyo esigqini se-sinus..
Isimiso sayo sokusebenza sisebenzisa kakhulu indlela yokukhipha i-RLC damping, njengoba kuboniswe esithombeni:
| Idatha evamile | |
| Amandla | 100~500J |
| I-voltage | 2000~5000VDC |
| Umthamo | 32~200UF |
| Umthwalo wokukhipha ishaja | 20Ω/50Ω/100Ω |
| Ubuningi bokushaya kwenhliziyo | 100~1kA |
Qala ngokushaja i-capacitor yokugcina amandla C ukuze i-capacitor ithole inani elithile lamandla. Ngesikhathi sokwelashwa kwe-defibrillation, i-C, i-inductance L kanye nomzimba womuntu (umthwalo) kuxhunywe ngokulandelana ukuze kwenziwe ukwelashwa kokushaqeka kukagesi 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
Ngokusetshenziswa ku-defibrillator, i-CRE film capacitor inomklamo okhethekile owenziwe ngokwezifiso, onezinzuzo zokusebenza okuphezulu:
Uma kuqhathaniswa nokuphila kwenkonzo okuphindwe izikhathi eziyi-10,000 emakethe, ukwakheka kwesakhiwo sefilimu ekhethekile kwenza izikhathi zokuphila zokushaja nokukhipha zingaphezu kwezikhathi ezingama-30,000
Uma kucatshangelwa ukusetshenziswa kwendawo engaqinisekile neyinzima njengangaphandle, isebenzisa umklamo okhethekile wokulwa nomswakama kanye nokumelana nokushisa okuphezulu, onokwethenjelwa okuphezulu
Ikakhulukazi ngomklamo omncane we-external automatic defibrillator (AED) (njengezidingo eziphathwa ngesandla), kusetshenziswa izinto ezisebenzisa amandla amaningi, umthamo kanye nesisindo kuncane ngo-50% kunomklamo ojwayelekile.

Thatha imikhiqizo yethu kanye nabakhiqizi ababili abavamile emakethe ukuze wenze ukuqhathanisa okufanayo kokuhlola. Ngaphansi kwezimo zokusetshenziswa zokushisa okuphezulu kanye nomswakama, imikhiqizo yethu inokuphila isikhathi eside.
Izimo zokuhlolwa:
1. Izimo zokuhlola ezimile: umthamo werekhodi, ukulahleka, ukumelana okulingana nochungechunge. Amapharamitha amile aqoshwa njalo izikhathi eziyi-10,000 zokushaja nokukhipha. Ukuze kuqinisekiswe ukunemba kokuqoshwa kwedatha, izinga lokushisa le-capacitor kufanele lisondele ngangokunokwenzeka ekushiseni okuzungezile lapho kuqoqwa. Ukuhlolwa kwenziwa ngomehluko wokushisa ongu-≤5 ℃.
