Daim Ntawv Thov ntawm Zaj Duab Xis Capacitor
hauv Cardiovascular Defibrillator
Kev siv tshuab defibrillation yog tib txoj kev zoo los kho tus neeg tuag sai sai hauv lub plawv
Lub tshuab defibrillator rau lub plawv tam sim no yog cov khoom siv cawm neeg mob uas siv dav heev. Nws siv cov hluav taws xob pulsed los ua haujlwm rau lub plawv, siv kev kho mob hluav taws xob shock, tshem tawm cov teeb meem arrhythmia, thiab kho lub plawv kom rov qab mus rau qhov sinus rhythm..
Nws txoj cai ua haujlwm feem ntau siv RLC damping discharge method, raws li qhia hauv daim duab:
| Cov ntaub ntawv ib txwm muaj | |
| Lub zog | 100~500J |
| Hluav taws xob | 2000 ~ 5000VDC |
| Muaj peev xwm | 32 ~ 200UF |
| Tso tawm load | 20Ω/50Ω/100Ω |
| Qhov siab tshaj plaws tam sim no | 100~1kA |
Ua ntej, them lub capacitor C kom lub capacitor tau txais qee qhov zog. Thaum lub sijhawm kho defibrillation, C, inductance L thiab tib neeg lub cev (load) txuas ua ke los ua kev kho hluav taws xob rau lub plawv tib neeg.
●Lub zog khaws cia
Lub zog hluav taws xob tau them rau hauv lub cuab yeej khaws cia zog ua ntej lub tshuab defibrillation shock. Kev sib raug zoo ntawm lub zog khaws cia rau hauv lub capacitor thiab qhov hluav taws xob ntawm lub capacitor:
E=½ cub²
Rau daim ntawv thov hauv lub tshuab defibrillator, lub CRE zaj duab xis capacitor muaj kev tsim tshwj xeeb, uas muaj kev ua tau zoo dua:
Piv nrog rau 10,000 zaug kev pabcuam lub neej hauv kev ua lag luam, qhov kev tsim qauv zaj duab xis tshwj xeeb ua rau lub sijhawm them thiab tso tawm lub neej ntau dua 30,000 zaug
Xav txog daim ntawv thov ntawm qhov chaw tsis paub meej thiab hnyav xws li sab nraum zoov, nws siv cov qauv tiv thaiv av noo thiab kub siab, uas muaj kev ntseeg siab dua
Tshwj xeeb tshaj yog rau qhov tsim me me ntawm lub tshuab defibrillator sab nraud (AED) (xws li cov kev xav tau ntawm tes), siv cov khoom siv zog siab, qhov ntim thiab qhov hnyav yog 50% me dua li cov qauv tsim ib txwm muaj.
